MANUFACTURING HEAT TREAT

Heat Treat Radio #87: Advances in Work Flow Planning Software with Jeffrey Halonen

While this Heat Treat Radio episode about the advances in work flow planning software will be more interesting to our commercial heat treating friends, we think this topic is a fascinating one that speaks to Industry 4.0 and IIoT questions. The question: How are data and human machine interfacing technologies advancing to make the heat treat experience more efficient?

Watch, listen, or read about it in this Heat Treat Radio conversation between host and Heat Treat Today publisher, Doug Glenn, and Jeffrey Halonen, CEO of Steelhead Technologies.

Doug Glenn:  We’re looking forward to talking to you today about what is a growing interest, I think, to a lot of people in this industry, primarily because of the growing of technology and data and things of that sort. I know your company is heavily invested in job shop, plant-wide, organization-wide operating systems. That’s basically what we’re going to talk about today.

The first question I wanted to ask you is, what do you think are, for job shop-type businesses, the two or three main reasons that makes them less profitable than they might otherwise be?

Jeff Halonen
Co-founder & CEO
Steelhead Technologies

Jeff Halonen:  Great question. A job shop is a unique business. They don’t have the luxury of centralized planning, or planning in advance and architecting a plant, like they might do if they are making Chevy Tahoes where an immense amount of engineering goes into build a highly efficient operation so it’s highly predictable.

A job shop, on the other hand, is the opposite of predictability. Down to what parts, what hour, what time of day, how many customers, by week, by month. . . everything changes constantly. That buys a lot of inefficiency, not because what they do is overly complicated; it’s the complexity that grows both with a high quantity of customers and a high quantity of specifications they need to build to. Then, obviously, being at the end of the end-customer’s production cycle, the lead-times are often very high pressure because you have to make up time for all of previous mistakes and missed deadlines. You’re the last step before it gets on a plane or a train or goes straight to the customer.

We’ve seen room to improve these operations from a profitability and a data standpoint. Data is not something you’re going to be able to sell out in the market. In your plant itself, it is not very valuable, but it’s the decisions you can make with that data. Specifically, this is the case when it comes to profitability. For example, if you have five to twenty different processes or lines, which one is more profitable than the other? That should be something that you understand. This is what your business does: different types of business, even different part numbers, different customers, different lead times that you offer for customers, what’s your cost versus return on that.

The other opportunity, aside from analyzing the commercial side of all of your work, is your production. If you’re a job shop, generally you are parts in and parts out, go, go, go. It’s more of a service business than a slow moving, very technical manufacture.

So, basically, every time a job comes through your shop, you should be studying — what does it take to make that job go? Anything from the quote, to closing the sale, to receiving the order, to the physical paperwork, to notifying the floor, to building a schedule, to scheduling capacity, to executing production, providing instruction information, how you collect that data, even something as simple as how do you notify customers. Are you notifying customers on the phone or an email? You do twenty to thirty orders a day, 100 orders a day — it adds up quickly.

Invoicing — how do you generate your reports? Aggregate data — that’s the other thing that we see in job shops very frequently. The actual cost of executing an order on a marginal basis can be extremely high if you have many systems; or it’s paper-based; or it’s not streamlined.

Doug Glenn:  Not just the processing of the part, in the sense of thermally processing the part, but you’re talking all the way from preparing the quote all the way through to shipping and anything at the end.

Jeff Halonen:  Absolutely, Doug. In our experience, the job shop manufacturers are pros at what they do — the actual process. They’ve been doing it for years or sometimes decades. They have it absolutely dialed. In the physical processing of the part, sometimes there is room for improvement; but a lot of times that is a fine-tuned machine. Generally, it’s the business systems that surround it.

One thing that we like to point to is the very heavy investments that the industry makes in physical, tangible goods: natural gas, land, equipment, people, automation systems  (physical automation systems). Where we see a huge opportunity is all the things you can’t actually touch and feel. It’s the digital operating system that your plant runs on, all the systems and processes that makes your business tick.

Doug Glenn: You’re talking about data in, from the very beginning of the process, all the way through. I don’t know too many companies, especially job shops, that are actually gathering that type of data. Is it possible? What are the costs involved, let’s say, of starting to gather that data from that point all the way through? It seems like that would be expensive and difficult to do.

Jeff Halonen:  Absolutely, Doug. It feels like an asymptotic target. You can try really hard, and you can make progress; but that rate at which you make progress drops off really quickly. It’s what we see as a balance of cost of data and value of the data.

It’s not that manufacturers don’t value the data; they often do make an investments to get the data. They realize quickly that, with help with the proper tools, cost ramps up really quick. They essentially hit that floor or that asymptote, if you will, really quickly. They say, “OK, we are clearly extending more effort than it’s worth; so we’re going to dial it back. We’re going to go right here. That’s where we’re setting the knob, and we’re going to run our plant.”

Unfortunately, with the tools available, that setting or their status quo tends to be paper, Excel, systems like that. If you have no system at all, not even paper, it’s very obvious that we need something. We write on paper, we highlight, we put it here, we do this, we do that, we have a whiteboard for scheduling, and you see a lot of yield from essentially those data systems.

They are rudimentary data systems, and the cost is very low. You spend a week or two, and you deploy it. You make it, run it, and get the value. Then you say, “Now, I want to track what part was in what oven at what exact time and exactly what went through. Now I want to see all the parts that went through this or that type of process. We’ve run that part number forty times — I want to see its performance every single time from a commercial standpoint. All of a sudden, the cost of obtaining that data — now you just have a wish list. You look out and say, “That’s going to be impossible. That’s way too much time to get that data.”

That’s really where deploying a centralized platform that  takes in everything from the business — anything from inventory, to quoting, to operator instructions, to timing each process, to part numbers, to shippers, to invoicing — it all really is intertwined. When you can track every single movement of every single part going through the entire process, the cost of that data drops precipitously. Especially if you have reporting integrated. Now you can generate reports that will passively collect data as your operations go on. Whatever you look at on a daily, weekly, monthly basis to essentially run your plant.

We like to say, “Digitize, automate, optimize.” To us, these are  three core steps to reducing the cost of data. First, digital. If you have no system, or you have paper, it’s very difficult to obtain actual data and actual insights from your plant. Even if you do digitize successfully, but you just have a mass of huge databases, that’s very low usability because now you need to be essentially a data scientist to go in and make it useful.

Next is automation. We need to automatically tailor the data to present profit margin. We need to automatically tailor the data to track reworks. That’s the next step because that gets us to actionable data information.

Then, the last is optimization. The optimization itself often actually happens at the plant level where the management team is now in, what I would say is, a luxurious position of having a lot of their systems digitized then automated as well.

They have the data. They have the time to address it. Now they’re in the position of optimizing their facility. That could mean focusing on marketing; that could mean pursuing a new industry — developing a new process, training your operators. It could mean anything in the world — getting a new permit from the city, for example. These are things that optimize your plant to provide as much value as possible to the world. You have the ability to do that because you’ve done your homework to get your plant into a position to action that data and have the time available as well.

Doug Glenn:  Right. You’re collecting the data that you need to make those types of decisions. I find it interesting some of the scope of the types of decisions you just mentioned, that job shops could make based on the data. That’s pretty interesting.

Let me ask you this, Jeff:  do you have any examples in the heat treat world? Or where, for example, in the heat treat world do you envision there being some real business efficiencies here? Let me preface this one other way, too:  a lot of the people that listen to this podcast are not necessarily job shops; they are what we call “captive heat treaters” who run high volume/low variability. But there are some who actually run high variability — a lot of different parts,  maybe not exceptionally high volumes, or at least smaller volumes than our captive heat treaters. I guess, addressing those guys, or even the guys that run low variability - what are the business efficiencies we could see?

Jeff Halonen: It’s going to be different from plant to plant as far as the value you’re going to have because everyone has different proficiencies and profiles like you just mentioned. If you’re in a situation where you have a very high degree of mix, one of the huge inefficiencies that we’ve seen is they want to keep a really tight lead time; but they don’t have the ability to quickly and easily schedule efficiently. They keep all of their equipment at maximum capacity, so they keep as much throughput in the plant as possible. The inefficiency essentially shows itself in the quantity of ovens - they just simply invested in more equipment and just keep more ovens hot. They essentially overcapacitize which is both acap efficiency and an opex efficiency because you have to heat, maintain and run that much more equipment. That’s an environment where you have a lot of complexity, and the scheduling required or the inability to schedule efficiently is leading to capital inefficiency.

If you’re in a position where you’re on the other end of that spectrum, as you mentioned, Doug, where you have lower variability by part number higher volume; some of the inefficiencies there can definitely be more on the data systems — the data processes. Again, scheduling — if it’s a very simple schedule, you can schedule it very quickly and easily and very efficiently because you don’t have a lot of change. It is tracking that information — where are all the parts, for example.

A lot of times it’s the administrative time. People are walking out, still trying to find where the parts are. Simple things like order status or we ran this part with this lot number or purchase order or shipper number or whatever identifier you have — we ran this six months ago, what happened to that part? Often times, something as simple as that can turn into a 20, 30, 40-minute exercise instead of just quickly finding that information.

Doug Glenn:  How about equipment inefficiencies? How can a system like yours that’s gathering all the data - how can it help us increase efficiency, just of the equipment that we have?

Jeff Halonen:  The first step, as they say, to addressing an issue is knowing you have a problem. The first step is measuring what actually happens in the real world. You can walk out into any shop and just open your eyes and things are happening, right? But your knowledge of what’s happening is almost just instantaneous. As soon as you go to the ball game later, you’ve forgotten all about that pile of parts or that empty oven that you saw. If you have a situation where at the end of the day, week, month, quarter, you have the raw numbers - we know it can do X amount of parts or racks or  pounds or whatever the metric is - and it did Y and that’s X percentage below that number, the numbers speak for themselves.

As far as what the team can do to address the problem, that could be any number of things from a plant management standpoint. That’s where it really gets into the optimization side. Although one thing might be scheduling efficiency. If we find that turnovers or essentially thermal profiles or run speeds or whatever it may be, if we have an opportunity to batch production,  increase density which might be a scheduling exercise, we might explore that.

That could also come back into business strategy — it’s all very related. For example, you might offer to expedite fees — fast turnaround at a higher price — but then lower price for long turnaround time because that now gives you the privilege of organizing your work in a more efficient way and providing the same value at a lower price. If that end customer has the time in their schedule, they can say — hey, I want to save money and have my job done in a week or so instead of 24 hours where I’m ready to pay a huge premium. That cost multiple can be dramatic and for good reason.

Doug Glenn:  I have two more questions for you. One is a little bit hypothetical. I want you to kind of take a guess  about the rate at which software and digitization, of the sort that you’re talking about, is coming into job shops. That’s the first thing. The second and last thing I want to ask  is for you to just kind of take us on a walk through, to the best that you know, a heat treat business. How might a system like yours look?

A lot of people say, “Listen, I’ve got my system in hand, I’m okay the way I am.” First, is it coming? Do you think people are going to have to get to this digitalization sooner or later?

Jeff Halonen:  I believe so, yes.  I understand you can definitely run a shop on paper. You can run it on Excel. As far as macrotrends out in the world, consider first the technology available. The team at Steelhead is obviously very competent with a lot of really great software engineers, but the tools available have progressed dramatically over the last couple of years. We’ve run into heat treating shops that are using a system they may have installed in the ‘90s. It does functionally work, but we do see a lot of symptoms, essentially adverse symptoms, to the business by choosing to use a less effective system. That usually comes in less actionable data. It does facilitate the physical paperwork needed to run your plant, but it’s not a competitive advantage. It just is kind of there, and it’s just kind of barely acceptable. The employee morale is not great - people don’t love using systems where they have to reenter data. They can’t work from home. There are so many different currents that are coming in there.

The other one is the end customers often like more and more visibility and more and more traceability into plants. Transparency, visibility, traceability. I don’t think it’s a situation where it’s going to become unviable to run a shop without really advanced technology. I do think, over time, it will be a situation where the competitive profile is one where there are clear advantages to the shops that embrace the wholistic business advantages that come with that.

Think about your customers — they’re buyers just like anyone else. Everyone loves shopping on Amazon or their favorite website. They get the notifications; they can track everything. You order a pizza at Dominos, and you can see them rolling out the dough and putting on the sauce. The predictability and the visibility is something that is really important.

I think, over time, it is certainly something that the end manufacturer is really going to continue to drive (even automotive, traceability and everything like that). As the requirements of data go up, and the competitive landscape starts to adopt more and more of this technology, it’s going to be more and more of a disadvantage in the competitive landscape to be not at the cutting edge of that technology.

Doug Glenn:  Pretty soon it’s not going to be cutting edge, is my thinking. As more and more people are adopting it, it’s going to become easier to adopt. I’m assuming it’s going to be easier to install, easier to launch into any business.

Take us through that, as a job shop. Any of either our captive heat treaters that have a high variability of products or a lot of our commercial heat treat shops which have high variability of products — how would it look? Start us as early as you can in the process and walk us through it.

Jeff Halonen:  Starting at the beginning of the process, if you say, “I’m interested. I need a system. I can just feel it. I can see it. I know there is opportunity to improve our business.” Or, “We feel like we really optimized everything about our business, but we still feel like we have restrictions on growth.” This could be — it takes a lot of energy from the management team, the ownership team that are involved. One question I like to ask is: if the business going through your business or business unit doubles, do your headaches double? Do the amount of hours you work double? To me, that’s symptomatic of room for system improvement.

Early on in the process it starts with some level of interest, some level of intrigue. I think this is something we can improve on; our plant manager is complaining that they can’t work from home. Whatever all these issues are that manifest themselves; or you’re losing jobs in quoting, and you’re not sure if you’re a high price or a low price or margins might be unclear; you’re not satisfied with the level of data. Basically, that’s generally where we start our conversations with plants.

We really take an approach of both informing about what’s possible on the tool and what’s impossible on a modern platform.  Then we also do a value assessment. How do you do this? How do you do that? That kind of third party provides a great, almost, sounding board to say, “Okay, here’s an itemized list of room for improvement.”

Honestly, that’s what really makes it compelling. When we can sit down with a potential partner and identify how we can actually improve the business in very real and definitive terms, not just insights that you can use to drive your business. Also here’s how much time you spent here, how much time you spent there. It’s a combination of calculating hard costs and hard opportunities and then the upside with the actionable insights from the system.

From there are the deployments at Steelhead. [blocktext align="center"]We do direct-to-direct service, so no third parties. A Steelhead team member will essentially go through a lot of meetings and plant walks, in some cases, and essentially reverse engineer your plant.[/blocktext] Where do parts come in the building, and then what? Then they go here? Do they always go there? Sometimes. Can they be run together? We will ask a million questions to essentially reverse engineer the flow of your plant, and then we design the system to reflect your current operations. Not - here’s a software, now bend your plant over backwards to match the software. Whether it’s quoting, workflow automation, or reporting or any of the other parts of the system, we’re going to want to ask as many questions as possible to configure the system to match your plant.

Doug, you mentioned the cost is going to go down, over time, of technology. Absolutely. Because one thing we can do very quickly since our platform is essentially kind of like a build-your-own; it’s almost like Excel except it’s Excel that is highly, highly engineered to work for this specific industry. One thing  we can do is we can prove it out really quickly. So, in just a few hours or a couple of days, we can essentially build your plant, or a part of your plant, and then run your work through your plant and say, “Okay, pick up a quote and let’s write this quote. Here’s a purchase order, let’s do the purchase order. Let’s take this tablet and go out to your plant and step it through your exact operator interfaces. Let’s collect that data. Let’s track it; let’s sit down in the conference room. Let’s pull up the reports, the inventory.

That’s one thing that we really like to do early on — whether it’s in the late sale cycle or evaluation or sale cycle or early on in deployments — is prove it works. Because one of the things we’ve seen time and time again are the horror stories with plant operating software:  we’ve tried for 18 months and we put in tens or hundreds of thousands of dollars, and we pulled the plug. We went back to whatever we were using before. So, proof of concept really quick.

The other thing is the actual deployment going fast. We like to go hot and heavy, kind of rip the Band-aid off, not drag it out over months. We like to go 2-4 weeks, training the team, iterate, iterate, iterate, test, test, test, test, test, because everyone says how it should work. We build it, and we test it and then there are always a couple of tweaks.

From there, we have a customer success team, as well. Whether it’s a phone call, email, zoom call, or training, we like to have someone available to answer the phone. Our philosophy is that your digital infrastructure isn’t something that should be optimized for low cost because we feel that the service that comes along with it — including a team of experts — is critical. Like a wiring harness for your automobile, it runs your entire plant. When your plant changes and you have changing requirements, to have “pros on your bench” to make adaptations real time in your plant is highly valuable.

Our approach is full service. We kind of own the functionality of the system in your plant — anything from the deployment to ongoing support. We’re always one degree away from engineering, as well. Occasionally when there is a bog or something is not working properly, our engineers are right there on calls with customers to make sure everything is working properly.

Doug Glenn:  They can jump into the system and reprogram, as necessary.

Jeff Halonen:  Absolutely.

Doug Glenn:  Run us through this one then, if you would: Let’s say there’s a company — and you’re going to have to take a very generic-type job shop — that has your system already. It’s fully integrated and everything is working well. What does it look like? The reason I ask this is question, is I think a lot of people have trouble envisioning what it would look like and how it would be different than what I’m doing now.

So, a company that has your system, they go to do a quote for a job, and they receive an inquiry. Is the process they follow any different than what they would have done before your system was there? Let’s just take that first step, process and RFQ: how is that going to change from if they didn’t have your system?

Jeff Halonen:  Something like quoting can be a fairly dramatic change, depending on what the current system is. Current systems can be Microsoft Word and Microsoft Outlook and maybe an Excel sheet to track the quotes. A lot of time to administer them and then there is pretty limited visibility. The transaction that we’d see there with Steelhead is that you can actually build a fully automated quote so you can define the algorithm: all of your flow charts, your Excel sheets, square root functions, looking at the mass of the part, specific gravity, material, etc. We can even reference the current price of natural gas. So, you can build models to reflect how your business runs and reference the past performance of that job.

What that looks like for quoting is that you’re able to build the quote all in one system. You might have multiple people involved in the quote: one person is working with the customer to verify requirements, verify inputs, ask questions, gather more data, and then it lands in someone else’s inbox. Now, a streamlined workflow allows the owner or the plant manager or sales manager can now approve that quote and then sending it to the customer instead of sending it through email and downloading and moving things around, we can send it right out of the platform, attach a file. We can track and see when the end customer is opening the quote. Also, your sales team has a lot of tools. They can say, “Hey, what quotes have never been opened? Hey, we should probably make a phone call. We put a lot of effort into those quotes, why don’t we call them and see what’s going on?” There are a lot more analytics but also just speed.

Another thing we’ve heard a lot is that a customer calls, they send a purchase order that references a quote to go, and find that quote can be a challenge because it’s in someone’s inbox, unread. Instead, they can have one platform to grab the quote, convert it to an order, and now you’re running production! It’s all the same data, it’s your plant. You’re not going to start quoting using different laws of physics. It’s about streamlining what you do today and replicating what you do today, but improving the customer experience, improving your team’s experience, and quoting faster, which leads to more jobs.

Everyone wants the thing quickly. If you can go from two days to two hours or from five hours to five minutes, that can have a dramatic impact on winning deals. For example, I’m in Chicago on vacation, and a customer calls, asking, “Where are my parts?” or “What happened to these parts?” Option A is you’re making phone calls back to homebase, someone is rummaging around looking for the information, and it’s not very enjoyable for you, your team, or your customer. But, it could be you put that customer even on speakerphone or mute, look for 30 seconds, and just text them the file right off your phone in real time! It’s the speed of accessing data, customer service, and actual insights, but a lot of it is workplace satisfaction.

We’ve literally been in shops where people are threatening to quit saying, “Our system is so bad” right in front of the president of the company. . . “I’ve been saying for years, we need a new system. I’m at my wit’s end because what I have to do is so painful and repetitive every day just to make the plant go.” It can manifest in a lot of different ways.

Doug Glenn:  Give me a quick history on Steelhead.

Jeff Halonen:  Steelhead Technologies was founded early in 2021 by a team of software engineers, mechanical engineers and manufacturing engineers. We started with the need of a single customer who talked about their pain. This particular customer was running on paper; whether it was contacting customers, instructing operators, tracking information, finding information, even something as simple as a customer calling with a phone call asking for information on a job, all were huge disruptions in their day. It took half an hour and they had to physically go find people and paper. Everything was in a huge storage room at the end. What the Steelhead team heard was a high degree of pain and essentially a plea for a solution. So, we founded Steelhead Technologies to address that need.

Source: Steelhead Technologies

The team has grown really quickly, and we’ve raised 2.5 million dollars in investment capital here in 2022. The team went from an original team of about 6 to up to 16 now. As I mentioned, everything is kind of the direct service model. Whether it’s sales, deployments or customer success, it’s all team Steelhead across the board. Everyone is an expert in the platform, and everyone is one degree backed up by our team of engineers. We have six engineers that work fulltime on Steelhead making it the best that we can.

Our customers are amazing. Everything that we work on is driven by a customer request, someone out in the field, using the tool and saying, “Hey, what if. . . ?” or “Hey, this could be better” or “This extra effort. . .” or “We would really like to know this. We are trying to achieve this business objective, but we need that.” That’s really where the Steelhead team excels is taking essentially what we view as requirements and building a platform to meet those requirements.

It's really exciting. What we found is that [we can really help] the job shop industry, specifically, and also the high throughput — or even the high-mixed captive shops as you mentioned — where there is no build materials, no engineering team, no design release, and no supply chain. It’s go, go, go. The assumptions change by the day, hour, or minute, and everything is fast paced. We’ve seen a huge lack of automation and data in the space. With high quality, purpose-built technology for this fast-paced, almost, service type of manufacturing, with specifically built tools, we’re able to achieve minimal effort to achieve each job. To minimize all of the administrative effort, but also aggregate extremely detailed data down to operators, part numbers, and equipment, without driving up costs or sacrificing ease of use. That’s our core strategy.

Our customers are incredible, and a lot of our recent success has been just keeping up with our customers since they’re always pitching for a new tool or feature. We roll out a couple thousand lines of code to address this and they’re like, “This is good, but it needs that.” That’s the other thing — software is a service, so we’ve long accepted that we are never going to build the software and just ship it: it’s a continual living beast, whether it’s cybersecurity, speed, everything. So much of it is service because this type of software [requires] pros to extract the maximum value from it.

Doug Glenn:  All right, last question. This is your challenge question for the session here. You, personally: What do you find most interesting and exciting about it? When you look into the future, what are you excited about?

Jeff Halonen:  What excites me the most is the transition that shops can see by adopting technology and systems whether it’s impact to the bottom line — which we’ve seen in some shops, where it’s really stunning — or something else. A marginal labor cost where one customer’s job takes three minutes and another takes nine minutes. . . The manufacturer can now address that 3X marginal labor cost with the data where, before, they were just eating it. “This customer is not profitable; we’re not doing that; we are no longer accepting batch sizes below X, because we’re armed with the data.”

What really excites me personally is the journey that each of these plants are able to go on. I also get really passionate about when I’m able to see a difference between the way things are and the way they could be. That’s what every single interaction with our partners is: we see the way that they are and we work really hard to build the best one possible. So, it’s like, hey, look at this difference? Look what we can do? It’s that sense of accomplishment on a customer basis to really get as much as is possible out of their time, resources, people and their entire enterprise.

Doug Glenn:  It’s kind of nice seeing the smile on your customer’s face, I think, right? When things go well, to be able to say, “Man, that was good!”

Well, Jeff, thanks. I really appreciate it. It’s very exciting. It sounds like you guys have got a lot of interesting things going on and, hopefully, some of our readers/listeners/viewers will be able to give you a call but thanks for joining us.

Jeff Halonen:  Thank you, Doug. Thank you very much.

Delve into Data and Digitization in the Heat Treat Realm

OC

In preparation for Heat Treat Radio episode #87 (looking at ways to increase productivity especially with data management) coming tomorrow, take a look at these three articles from the Heat Treat Today files to get you warmed up. No matter where you are in the digitization process, you'll find something to help here. 

Taking the step from a paper and whiteboard system to a computerized system is a big jump. Maybe that's been done, maybe that's still being considered. Already digital? Then there are always efficiency and organization improvements to run an even more productive shop. Lastly, what does the future hold? How best to stay on the cutting edge of data management?

Read this original content article for guidance and encouragement in the use of digital systems for the heat treat shop.


1. Heat Treat Control Panel: Best Practices in Digital Data Collection, Storage, Validation

Heat Treat Today asked six heat treat industry experts a controls-related question, "As a heat treat industry control expert, what do you see as some of the best practices when it comes to digital data collection and storage and/or validation of instrumentation precision?" This article gives reasons for why you collect and store data and some helpful ideas for making sure those records are preserved.

Contact us with your Reader Feedback!

One expert had this to say: "electronic data must be validated for precision; checked; and calibrated periodically as defined by internal procedures or customer standards. Data must be protected from alteration, and have specific accuracy and precision."

Tony Busch, sales application engineer at Control Concepts, Inc., takes a look at digital maintenance systems. These systems play a part in recording and monitoring data, and they contribute to the overall productivity of the heat treat shop. This article makes a strong case for intelligent controllers.

"Digital power controllers can calculate resistance and provide precise power control. Predictive maintenance is achieved by knowing when an element has reached its useful life. Intelligent power control includes embedded algorithms with teach function to calculate data and predict what is likely to happen next in the life of a heating element," emphasizes Busch.

3. DUAL PERSPECTIVES: The Heat Treat Shop of 2050

Global ideas emerge in this article, as two men from very different locations, give some thoughts about digitization in the next 20 years or so. Hear from each expert - one representing the European market; one representing the North American market - as they discuss the role of technology, the human element, and heat treating of the future.

Thomas Schneidewind says, "digitization must always remain only a tool, not an end in itself." He reminds readers that importance always must be placed on the human element. Doug Glenn counters with, "For commercial heat treat shops where variability is high and volumes are relatively low, much of the same will be true with less and less human interaction needed."

The Role of Heat Treat in Binder Jetting AM for Metals

OC

Additive manufacturing (AM) at a commercial scale began about 30 years ago and has expanded well beyond its original scope. As AM becomes increasingly prominent across different industries, heat treaters need to know how to handle AM parts in their shops. Learn about the history of binder jetting AM, the alloys used in this technology that require heat treatment, and what heat treaters should expect for the future.

Read why Animesh Bose of Desktop Metal thinks that binder jetting AM is only going to be used more and more in several heat treating sectors.

This article first appeared in Heat Treat Today’s December 2022 Annual Medical and Energy print edition.


Binder Jetting of Metals: Origins

Additive manufacturing (AM) at a commercial scale began about 30 years ago and has expanded well beyond its original scope. At the beginning, rapid prototyping (RP) was the name for the burgeoning technology; it emerged in the 1990s to bridge the gap between the need for quickly produced prototypes for manufacturers, not just plastic replicas. Rapid tooling (RT) of metal tooling parts joined RP R&D at this time as the research frontier for materials engineers. The current name for these technologies stands at “additive manufacturing,” or AM, though the popular terminology is simply “3D printing.”

Polymers

Developments in polymer AM also advanced rapidly with both extrusion-based technology as well as through advancements in Digital Light Processing of photopolymers. Stratasys Ltd., an American-Israeli manufacturer of 3D printers, software, and materials for polymer additive manufacturing as well as 3D-printed parts on-demand, began using a material extrusion-based process with their FFF (fused filament fabrication) technology to print parts, patented in 1989. This worked by feeding coils of polymeric materials though a printer, which would extrude the material through a small, heated chamber where the material would pass through a small orifice to extrude – or print – in a three dimensional design. This method allowed for very fine, hair-like material to print in a precise X ,Y, and Z motion, building layer by layer. Vat polymerization was another polymer AM technology that gained traction and involved photopolymer processing. Both technologies are currently used for polymeric materials. Interestingly, both processes have been adapted and are being used for metal 3D printing.

Metal AM

In 1993, an MIT engineering professor named Emanuel “Ely” M. Sachs – a man who could be considered the father of metal binder jetting technique – along with his colleagues from MIT patented the process of laying fluent, porous materials in layers between 50- to 100-micron thickness to form 3D parts. They were able to do this by spraying an organic binder on each layer of material where they wanted to increase the height of the part to produce a bonded layer in the selected area. This layering is repeated several times before the unbonded powder is removed immediately or after further processing.

One of the biggest advancements in metal AM happened in 2014 when GE Aviation combined multiple parts into one huge, complex design using a laser-based additive manufacturing method called direct metal laser melting. The end result was an airplane fuel nozzle made of 20 parts for the LEAP™ engine. All of AM came into the limelight, and direct metal laser melting – a melt-based technology – just took off.

But there were limitations to this laser process, the main one being cost and special powder requirements to layer and melt to form the part. The process was also technologically intensive and not fast enough for high volume production (as would be necessary for automotive or consumer good-type application).

Binder Jetting Technology

Binder jetting that had been developing in the early 2000s started to gain traction as a non-melt-based process for high volume mass production. Instead of melting the powder material, a binder is used to adhere the powder metal layers where needed. This method of printing results in a more uniform final part microstructure compared to the melt-based processes. ExOne, a binder jet 3D printing company, pursued the binder jetting technology using a license from MIT. In 2015, Desktop Metal was formed, and they focused on high volume mass production by binder jet using their Single Pass Jetting (SPJ™) technology. As binder jet gained traction, other companies entered the market (HP, GE, and Digital Metal). Desktop Metal recently acquired ExOne and efforts at developing standards for the technology are in full swing.

Heat Treating of AM Metals

Stainless Steels

There are two popular types of stainless steel for AM. The first is 17-4 PH, a precipitation-hardened stainless steel, which I like to call an “all purpose” stainless steel. When heat treated, one can achieve varying levels of strength, hardness, and elongation; and since it’s stainless steel it has a reasonable corrosion resistance. The aging treatments are already well-established – for example, H900, H1100, etc. The other popular grade is 316L, a non-heat treatable grade used in the food industry among others. Now, most stainless steels have chromium and nickel in decent amounts, so companies have developed a grade which is called “nickel-free stainless steel” for applications where people might be allergic to nickel. This class of alloy is also heat treatable. There are many more stainless steel grades that are being developed by the binder jet process.

Low Alloy Steels

Many low alloy steels are used in AM. For example, 4140 and 4340 have various, small amounts of alloying elements. These low alloy steels also need to be heat treated.

Tool Steels

Again, most tool steels are heat treatable. One of the most popular grades is H13; it is a tool steel that is heat treatable and can achieve fairly high hardness. It’s used for dies and other types of tooling.

Then, there is a category of tool steels known as A2 and D2; those are steels in which the strength can be changed through heat treatment.

Metal Alloys with Binder Jetting

There are also non-steel alloys that are used in binder jetting and require heat treatment. One example is nickel-based alloys, which fall in the broad category of super alloys. With some of these alloys, a heat treater would solutionize the part by taking it to a high temperature (950-1000°C), hold it for 60 minutes, and then quench in water, high pressure gas, or (in some instances) in air. The part then undergoes an aging treatment for several hours, depending on part thickness.

Additionally, there is a class of copper alloys with small amounts of zirconium and chromium that is heat treatable. These alloys have lower thermal and electrical conductivity compared to pure copper but have an advantage of higher strength and hardness over pure copper, which is very soft and malleable. For example, in applications that require additional strength and hardness compared to copper, the copper zirconium-chromium-based alloys may be appropriate since their strength and hardness can be increased by heat treatment.

This is just an introduction to the many alloys that have been used in binder jetting that need heat treatment.

Future of Binder Jet and Heat Treat

While heat treaters know about AM in the medical and aerospace industries, AM will likely gain more traction in the automotive industry. Presently, these are relatively small parts, but you will begin to see larger components coming from AM; one of the things to be aware of is that AM can create organic shapes, including all kinds of twisted and complex metal geometries. To ensure that these organic shapes do not distort or droop, larger parts must be well-supported. The development of a software known as Live Sinter™ by Desktop Metal offers the possibility of negatively distorting a complex shaped part (in the green state) so that after sintering, the part shrinks and distorts to eventually provide the desired complex shape at the end. This allows for the possibility of sintering parts either with minimal or without any support structures.

Heat treaters can also anticipate high volume AM production. This is one of the major focuses for binder jet engineers – to reduce costs for most automotive parts – as it will make AM very appealing to this cost-conscious industry.

Finally, optimizing sintering processes and related equipment for AM parts will result in meeting the production demands of the industry, and this will lead to AM parts being seen in heat treat shops more regularly. It would not be a stretch to consider (since there are heat treatments where gas atmosphere quenching at high pressures is possible), that the complete heat treatment cycle may be performed in the same furnace.

Cybersecurity Desk: The DFARS Interim Rule and What It Means for Heat Treaters

op-edAs the next installment in this series on cybersecurity, this third article will give you a better understanding of the Department of Defense’s DFARS interim rule and its requirements.

Today's read is a Cybersecurity Desk feature written by Joe Coleman, cybersecurity officer at Bluestreak Consulting™. This column is in Heat Treat Today's November 2022 Vacuum print edition. Refresh with part 1 and part 2 in earlier editions.

Cybersecurity Officer

DFARS Interim Rule

On September 29, 2020, the Department of Defense (DoD) published the DFARS (Defense Federal Acquisition Regulation Supplement) interim rule 2019-D041, Assessing Contractor Implementation of Cybersecurity Requirements, with an effective date of November 30, 2020. These new clauses are an extension of the original DFARS 252.204-7012 clause that has been required in DoD contracts since 2018.

The interim rule implements the NIST SP 800-171 DoD Assessment Methodology and the CMMC (Cybersecurity Maturity Model Certification) framework. The interim rule requires contracting officers to take specific action prior to awarding contracts, giving task or delivery orders, or extending an optional period of performance on existing contracts on or after November 30, 2020.

DFARS 252.204-7019 Clause: Notice of NIST SP 800-171 DoD Assessment Requirements

All DoD contractors in the Defense Industrial Base (DIB) must complete a self-assessment using the DoD’s NIST 800-171 Assessment Methodology and generate a points-based score. If the self assessment score falls below 110, contractors are required to create a POAM (Plan of Action and Milestones) and indicate by what date the security gaps will be remediated and a score of 110 will be achieved as part of the Supplier Performance Risk System (SPRS). At the time of a DoD contract award containing the new 7019 clause, a DoD contracting officer will verify that a score has been uploaded to the SPRS.

DFARS 252.204-7020 Clause: NIST 800-171 DoD Assessment Requirements

Along with the 252.204-7012 and 7019 clauses, the 7020 clause is approved for use in all DoD contracts. This new clause requires that contractors provide the government with access to its facilities, systems, and personnel when it is necessary for the DoD to conduct or renew a higher-level Assessment. The higher level Assessments are the Medium and High Assessments. The self assessment conducted as part of the 7019 clause is called a Basic Assessment.

A Medium Assessment is conducted by DoD personnel and will include a review of your System Security Plan (SSP) and how each of the requirements are met and to identify any language that may not adequately address the security requirements.

A High Assessment is conducted by DoD personnel onsite at the contractor’s location and will leverage the full NIST SP 800-171A (Assessing Security Requirements for Controlled Unclassified Information) to determine if the implementation meets the requirements by reviewing evidence and/or demonstration such as recent scanning results, system inventories, baseline configurations and demonstration of multi-factor authentication and/or two-factor authentication.

Along with that, this rule also requires that contractors flow down their requirements from 7019 to their subcontractors and suppliers. Just as the DoD may choose not to award a contract due to noncompliance, you may not be able to use a subcontractor or supplier due to their noncompliance.

DFARS 252.204-7021 Clause: Cybersecurity Maturity Model Certification (CMMC) Requirements

Heat treaters willing to move forward with these cybersecurity initiatives by the DoD will have an overwhelming impact on the DoD supply chain and your business. If many heat treaters in the U.S. choose to not embrace the mandatory requirements, the DoD and DoD contractors will award contracts solely to the few heat treaters who do choose to become compliant. Poor cybersecurity practices can result in hacking, loss of company data and critical customer data, and attacks by malware, viruses, and ransomware. All of this can result in major damage to the business and loss of customers, not to mention being liable for all losses and paying significant fines.

Complying with DFARS 7012 and NIST 800-171 is a requirement for all DoD contractors, subcontractors, vendors, and suppliers. The DoD has now begun confirming that contractors and subcontractors are compliant before awarding additional contracts. Navigating NIST 800-171 and DFARS is a complex and challenging — but necessary — step in this process.

This DFARS clause establishes CMMC into the federal regulatory framework. This requires that CMMC is to be included in all contracts, tasks or orders, and solicitations, with very few exceptions. The level of CMMC that is required will be determined by the DoD and added into the Request for Proposal. Contractors must maintain the appropriate CMMC level for the duration of any contract and the requirements must be trickled down to your subcontractors and suppliers. The CMMC certification is required at the time of contract award.

Watch For the Next Cybersecurity Desk Installment

My next article, number four in the series, will be: “General Cybersecurity Best Practices and What You Should and Should Not Do.

Heads or Tails, Philadelphia Mint Wins by Upgrading Heat Treat Furnaces

HTD Size-PR LogoThe Philadelphia Mint recently began a round of upgrades for its heat treat furnaces. Their function in the minting process is to anneal, clean, and dry the coin blanks to soften the metal prior to striking into coins, extending the service life of the striking dies.

SECO/WARWICK Group’s American subsidiary, located in Meadville, PA, recently began upgrades, a refurbishment of all five of the Philadelphia Mint’s heat-treating furnaces, one furnace per year. The heat-treating furnaces were originally installed there by SECO/WARWICK USA from 1994 through 2000.

All five furnaces are 4000 pound per hour rotary retort furnaces outfitted with a quench system, as well as a hopper feeder, a batch burnish barrel, and a batch/continuous drum drier. The furnaces are showing their age after a quarter century, so rather than nickel and dime the maintenance, the mint opted for a comprehensive refurbishment.

“Our Partner has plenty of coin to heat-treat, but they don’t have any to burn," commented Marcus Lord, managing director at SECO/WARWICK USA. "These waste-heat recovery and combustion efficiency upgrades are going to save them a mint while cutting carbon and NOx emissions nearly in half."

The small letter at the nape of Washington’s neck in the coin image above is a mint mark.  The “P” indicates that the coin was struck at the Philadelphia Mint.

To reduce energy consumption, the Mint is replacing insulation, roof panels, and radiant tubes as well as upgrading the loading systems. More energy efficient burners are being installed, along with recuperators to preheat the combustion air, to improve energy efficiency and use less natural gas. Mechanical improvements include replacing drive motors and two-speed gear boxes. The retort can over-heat and warp if the rotary retort unexpectedly stops before the cool-down cycle. As a failsafe, SECO/WARWICK added a pneumatic backup motor that can run the gear box off the Mint’s compressed air reservoir during a power outage.

The mint was established by the Coinage Act of 1792, when Philadelphia was the nation’s capital. It was the first public building constructed under the direction of the recently formed United States government. The machinery was powered by a horse walking circles in the basement.

Heat Treat Radio #86: Looking Ahead to Thermprocess 2023 with Timo Würz

As 2022 comes to an end, we’re taking this episode to look forward to what North American heat treaters can expect in the largest trade show for heat treaters anywhere: THERMPROCESS 2023. Doug Glenn, publisher of Heat Treat Today and Timo Würz, managing director at VDMA Metallurgy and General Secretary of The European Committee of Industrial Furnace, Heating and Metallurgical Equipment Associations (CECOF) talk about what attendees and exhibitors should expect and several of the hot topics in manufacturing that will be guiding this event.

Below, you can watch the video, listen to the podcast by clicking on the audio play button, or read an edited transcript.


 

Heat Treat Today is cancelling the North American Exhibitor Group. Please disregard the comments in podcast above or transcript below referencing this.

The following transcript has been edited for your reading enjoyment.

Doug Glenn (DG):  Welcome to another episode of Heat Treat Radio.

Contact us with your Reader Feedback!

DG:  Let’s talk about this. I know you are involved, in your capacity, with VDMA and CECOF and things of that sort with the THERMPROCESS event which is coming up in June. For people who might not know what THERMPROCESS is, can you give us a 30,000-foot view of the event?

Timo Würz
Managing Director at VDMA Metallurgy
General Secretary of CECOF
Source: LinkedIn

Timo Würz (TW):  THERMPROCESS is the world-leading tradeshow for the thermal processing industries. And it’s not just one show -- THERMPROCESS is part of a tradeshow quartet. It’s four shows, and they are all about metallurgical equipment, metallurgical processes, thermal processing, foundry equipment, foundry applications. All of these topics are very much connected one to the other, and that makes it a really big show. It’s not just this little part of industrial furnaces and burners, but it’s imbedded in a huge metallurgical environment. That’s the reason they call this exhibition “the bright world of metals.” You’ll find there any kind of thermal applications. If you want to process glass or ceramics, you'll find the respective equipment there. This is the larger context of this show.

It's really huge. The 2019 edition that was more than 73,000 visitors in Düsseldorf, more than 2,300-something exhibitors on all the four tradeshows. For the THERMPROCESS alone I think it was about 340-350 exhibitors and about 6,000 visitors only for the show, not taking into account all the others coming from GIFA show or the METEC show which are the other shows. So, there are a lot of symmetries between these shows, and you see really everything that has something to do with thermal processing -- with equipment, with applications- it’s really a big thing.

DG:  You and I both have probably been to the THERMPROCESS since early on, maybe its beginning. I’m not sure when the first show was, but I know the first one I attended was in 1999. It was quite an event, even then.

I want to give our listeners and viewers a sense of the enormity of it. You’ve been to some of the North American shows. I don’t know if you’ve been to one of the larger shows in Chicago like the IMTS. It’s probably one of the larger metal shows in the United States. My contention is, and I wonder if you’d agree with this -- McCormick Place, where the IMTS is held, the campus on which the quartet of shows, as you say, is being held, is probably four to five times the size of an IMTS show. I don’t know if you’ve got that comparison or not, but it’s much larger than any other North American show I know of.

TW:  I know IMTS quite well because I’ve been there many years ago when I was working for the machine/tool industry. That is really a big show in the United States. I think the FABTECH is about the same size or even a little bit bigger than IMTS. I would say, maybe THERMPROCESS and the other three tradeshows are even a little bigger. I don’t know if your readers know the exhibition crowds in Düsseldorf, but they are quite huge. I think it’s the second or third largest exhibition area in Germany. The four trade shows, they really occupy all halls at the exhibition center. So, 73,000 square meters -- that is about 150,000 cross square meters, so 33,000 is only the net square meters. If you take all of the other areas together, it’s really a huge exhibition area. Still, the comparison is not too bad -- it compares to the big shows in the United States in other industries.

DG:  Yes, I think so. I tell people, when I try to give them a sense of the size of the campus that the Düsseldorf Messe. If you were to start on one end and just walk at a normal rate, it would probably take you 15-20 minutes to walk from one side to the other which, fortunately, we don’t have to do too much.

The dates of the show?

TW:  It’s June 12-16, 2023, in Düsseldorf.

Düsseldorf, Germany

DG:  Which is a great time of year in Düsseldorf. It’s a lovely, lovely place, so I would encourage people to go.

Let’s talk about some of the trends, the international trends in thermal processing. From your perspective, what are some of those international trends, international things that are happening now that people will be able to learn about and hear about if they do come to THERMPROCESS?

TW:  There are a lot of things going on at the moment: there is the whole sustainability greenhouse gas reduction discussion going on. That is certainly going to be reflected at the show. There is digitization which is a very important issue for all industries but also for the metallurgical industries and the thermal processing industries. It gives you some new benefits you can offer to your customers, or you can benefit from in your product development. So, that’s a huge topic.

There is additive manufacturing that gives you completely new opportunities on how to produce certain parts for your equipment or how to replace a traditional technology. Think about replacing a casting by a part that is produced with additive manufacturing. Finally, the part is the same but the production process is completely different. There is a very interesting competition now between different production technologies coming out. That will be shown there and many, many others.

We could go into very specific details like new types of communication between machines and management systems or between different kinds of machines, and really a lot of interesting developments -- artificial intelligence, machine learning -- that all helps to optimize your process and your equipment, so that’s really an amazing development going on.

DG:  I’ve got a question for you:  I know you are kind of on the inside track with the whole Bright World Metals and Messe Düsseldorf, the organization that puts this on. Do you think that some day in the future they will add a fifth show on 3-D printing? There are a lot of metals going on here, right?

TW:  That is a very good question. I don’t know because there are still other exhibitions for 3-D printing and additive manufacturing. Maybe not necessarily a new show, but it is certainly becoming a permanent part of the existing show. One or the other place will really highlight that additive manufacturing maybe without having a fifth show to do it.

DG:  I think it would be interesting! We’d have to figure out instead of being a quartet, it would have to be a quintet, or something.

Let’s talk a little bit about the electrification. Let’s dig a little bit deeper into the electrification. What are you seeing there? I know, right now, you’re sitting in Florida, with tropical storm Nicole in your background. Is that the name?

TW:  It’s Nicole.

DG:  You’re sitting there in Florida, but I know you’re typically out of Germany. What are you seeing, Timo, there in Germany, regarding electrification and the move away from greenhouse gas, let’s say?

Source: Unsplash.com

TW:  That is a good question but difficult to answer question. Electrification is not really new. There are well-established processes which are already electrified. Think about induction heating or melting or electric arc furnace. That is all electrified heating equipment, so that is not really new.

The important question is, how many other processes could be replaced by electrified processes? Now, I mean such processes where you burn fossil fuel, for example, natural gas. That is really the point when it comes to greenhouse gas mitigation -- you want to get rid of greenhouse gases, and usually they are emitted when you burn something. From a physics point of view or an engineering point of view, electrification is great because it has a very high efficiency. Turning electricity into heat has a very high efficiency, much better than burning something and generating heat from burning fossil fuels.

The problem is -- think of a reheating furnace in a steelworks. In terms of energy consumption, which has to be called a monster because a reheating furnace in a steelworks consumes per hour as much energy as a jumbo-jet flying from Europe to the U.S., each hour. And now, try to imagine how to electrify such an application. At the moment it’s hardly conceivable that you can really replace that existing equipment by something that is electrified. You have the same energy density that is needed to get the process done. That is very difficult. You really come to technological limits.

I don’t say you can’t overcome them in the future; but at the moment, it is just not possible. But you have to see which processes are possible, and those which possible should be electrified. And for others, you have to accept maybe you need a hybrid concept -- electrical heating and conventional burner, or you have to accept that you have to burn something. In the future, maybe that will be green hydrogen. So, there are different roots.

Finally, green hydrogen is another form of electrification because you need electricity to produce green hydrogen. When you bring that all down to one point, it’s only a question of -- are you able to generate a sufficient amount of renewable energy? It’s not a question about the thermprocess aspect, it’s more or less a question about the generation of enough renewable energy so that it’s about wind energy, it’s about solar power, etc. If there’s enough renewable energy, I would say everything can be electrified or everything could be supplied with green hydrogen. That is not the main problem. The main problem is the availability of enough renewable energy.

DG:  I think our listeners would be interested in your perspective just on this one little issue: I know one of the drivers in Germany for electrification is the fact that you’re getting your gas supply cut off by friends to the East. I’m curious, how is it there in Germany with the lines being cut? The pipes being cut?

TW:  It’s really challenging. To be honest, we were used to having a cheap energy supply from Russia, cheap gas from Russia that was the fuel for a lot of parts of our life -- for industry, for private heating, and everything. So, that’s gone now. Now, we have a completely different situation. At the moment, fortunately, all our gas storage is full so we were able to fill them very quickly at very high cost because we had to buy all the gas, wherever we got it, and had to pay really insane prices.

So, maybe that might not really push electrification because, at the moment, a good part of our electrification strategy was based on burning natural gas as a kind of transition technology. Now that’s gone and we have to reactivate all the power plants which are already phased out. Now we reactivate the coal-fired power plants in order to have enough electricity. So, we have a big discussion about nuclear power because we phased out already most of our nuclear power plants. There are only three running. How long they can run to maybe support energy production?

On the other hand, we’ve seen friends that more than 50% of their nuclear power plants, at the moment, are not working either because they have technical problems or because the French rivers don’t have enough water due to the drought. You need the cooling water for the nuclear power plant. At the moment, we have to export electricity to France; usually it’s the other way around.

DG:  That is very interesting. I didn’t realize that. I knew there was quite the drought, but I didn’t realize that that had an impact on their nuclear power production.

TW:  Yes. At least in France, it is very bad. The whole situation is somewhat strange, at the moment. My personal opinion is that it will help us to transform our energy system much faster than we already tried to do. That is really something pushing us in a completely new direction. I think the renewable power generation will really get a boost because we don’t have that many alternatives. We have to rely on I don’t know how many ships from the U.S. bringing LNG or from Qatar or some of these places. It is a challenging situation but I think it will help to transform the whole system much faster.

DG:  We have a saying, and you may have something similar in Germany, but they say, “necessity is the mother of invention,” meaning, if you’ve got to do something, you figure out how to do it, right? You invent something to be able to do it. Such is the case with the power situation there in western Europe, for sure.

Well, we wish you luck on that.

Let’s talk a bit about digitization or the internet of things and things of that sort. Tell me what people will possibly see, if they go to THERMPROCESS in regard to digitization and IIoT.

TW:  I think digitization is not a trend anymore. It’s a reality and it’s a necessity for all companies. You can’t do any business without thinking about how to digitize certain aspects of your business. It helps on different levels. First of all, it is, of course, a great help to optimize processes. Think of using, for example, machine learning or artificial intelligence or whatever you might want to call it. You can generate optimized furnace recipes for heat treating processes, for example, which were then based on the knowledge of people, in the past. And they were quite good, but now you reach new levels of optimization just using these digital solutions or the transformation of data communication. You get a complete new level of transparency of what is going on in your system because every part has an IP address and can tell you what its stage is, what it’s doing, and what is maybe a problem. So, you have a complete new transparency of your processes of your equipment that you can transfer easily to management systems. You can base decisions on such data which then becomes information and that is something that really improves the overall equipment efficiency very much. That is a really big benefit for the customers.

Digitization is also the way towards new business models. So, having all your equipment, all your processes as a part of, let’s say, a digital or data ecosystem, it allows you to offer completely new products. For example, apps that help your customer to do the scheduling of the production or to allow you to have paper production concept or maybe helps you to do predictive maintenance and all those things. I think you will see all of this at the THERMPROCESS and the other three trade shows next year because, I would say, most of the companies, be it small or be it big, they  have such digital solutions now and they will show it in all different aspects and types of application.

DG:  Along that line, shifting gears just a little bit on this, one of the issues that we’re experiencing here in the United States is labor shortages and things of that sort. I don’t know if that’s exactly the same in Germany, but let’s assume that it is. How about automization and the use of robotics? Are you seeing anything along that line there, and do you anticipate that people would see some solutions or some ideas along that line if they were to come to THERMPROCESS?

TW:  Yes, we do have the very same problem. Finding young people, finding skilled people who are able to do their jobs in a highly sophisticated, industrial environment is terribly difficult. We have many, many jobs where we can’t find people for. Not the low wages jobs, but highly qualified jobs that require a lot of training. It’s exactly the same problem you have in the United States. And automization is maybe one aspect of overcoming that problem. Of course, a lot of companies do invest in automization, they do invest in robotics. Maybe not in the thermal processing industry. Robotics there is maybe different from what we maybe think of when we hear robotics like in automotive assembly, when you see maybe 2,000 robots working in a coordinated way, assembling a car structure. But any kind of automization that helps to overcome labor shortages being manipulating heavy pieces.

DG:  I think of fixturing and racking, right? I mean, that’s a heavily labor-intensive process, even if it’s small parts? Taking 100 parts and putting them in a rack so that they can be heat treated -- I think automization.

TW:  Yes. So, if you don’t find the people to do that, you certainly will have automization. You find all the big robotic companies and the automization suppliers on the four trade shows, especially in the foundry environment -- there is a lot of robotics. So, robotics manufacturers like KUKA, ABP and Fanuc, they are all there. They will show their special applications for the metallurgical sector. There is certainly a lot to see at the THERMPROCESS and the other three shows.

DG:  So, you and I both know that at THERMPROCESS and GIFA and METEC and NEWCAST, that it’s not all business. There is a little bit of enjoyment beyond business that goes on there. It’s also a little bit of fun on the show floor, but I would like your personal opinion: What do you enjoy about Düsseldorf? What is there for those people who would want to come over and do more than just work? What is there to see?

TW:  First of all, it’s taking place in summer and usually, at least the last two or three editions, we had really  nice weather. That helps a lot to get people in a good mood. Düsseldorf is a particularly nice city. It has an old part, Düsseldorf Altstadt, where you’ll find these typical restaurants and these typical Düsseldorf pubs where you get this special beer. That is really a place where people just meet and have fun. So, after the show you can go there and just have fun. You can talk business of course, if you like, but you can just have fun, drink a beer, sit at the banks of the Rhine river. The people are nice people. The people from the Rhineland, they are known as nice people. They have a good sense of humor so it is really a good place to come, do business, but also do anything else but business. It is a good place to be in June. There is plenty to do, and it’s a good place to have a lot of fun.

DG:  And it’s easy to get around, I must say. At the Messe or the fairgrounds, where the show is, the trains pull right in. They’re more like trolley trains, not necessarily subway trains, but it’s kind of what we think of in the United States as subway cars- they pull right into the Messe there. It’s easy to get on, it’s easy to get off. It’s 10-15 minutes to downtown. There is some great shopping for any of you ladies, or men if you’re a shopper, that you can easily take a walk down Königsallee which is a beautiful shopping place there and the Altstadt as you mentioned- all pretty much, which I think is nice, depending on where you stay in Düsseldorf . If you’re in the downtown area, it’s all relatively, if you’re in decent shape, in walking distance. You can walk it. I walked from the Bahnhof all the way over to Altstadt. You can do it; it’s not undoable.

TW:  That is all within walking distance, yes. And, if not, you can take the tram or the subway and it takes you 15-20 minutes, and you’re right in the center. Even if you want to go a little further- all the other large cities around are very well connected by this public transportation system. Never use a car in this area -- that is bad. In terms of traffic, if you are in a car, it’s a mess. Use the public transportation, and it’s wonderful because it connects all cities. You can easily go to Cologne, you can go to all the other cities around. It’s very easy.

DG:  In the past, they’ve had a bit of a technical program associated. Are they having that this time?

TW:  Yes, of course.

DG:  If you don’t mind, tell us a  bit about what you know about that technical program.

TW:  At THERMPROCESS, there is going to be the THERMPROCESS forum -- what was the THERMPROCESS symposium, in the past. It’s a kind of 2-day presentation program right in, I think, Exhibition Hall #9, so where the THERMPROCESS really is, where we have a two days with program presentations from exhibiting companies showing their innovations or showing new solutions, new applications.

We’re going to have at the first day, a special program that will try to dive a little bit deeper into the energy transition -- how the energy system will transform in the future. That is more from a scientific point of view, a political point of view, but nevertheless very interesting. Then we have the company presentations, and we are going to have the ‘tech talks.’ On Thursday, we are going to have the ‘tech talks.’ Originally, it was an online forum, but there we transfer it to the exhibition. So, three companies are giving presentations in a frame of a specific topic. They all build thematically on the other presentations so you see a whole picture of one specific topic. That is going to happen.

And there will be, of course, the foundry related events. There is going to be the ESTA that is the European steel technology application day. That is a very big event with seven hundred sessions over the whole exhibition. That is for the metallurgical people, so for the steel producers.

DG:  Good. That’s great. I thought that was going on but I wasn’t sure and I just wanted to confirm.

Timo, I thank you very much. I appreciate you taking the time to help us understand what might be going on at THERMPROCESS. Thanks very much for joining us.

TW:  It was my pleasure, thank you.

Steel Sustains

OCThe American steel industry is the cleanest of the leading steel industries in the world. Of the major steel-producing countries, the U.S. has the lowest CO2 emissions per ton of steel produced. By contrast, Chinese steel production creates carbon emissions that are nearly twice that of the U.S. per ton of steel produced. The global steel industry contributes 8% of total world greenhouse gas (GHG) emissions, whereas the U.S. steel industry only accounts for 1–2% of total U.S. GHG emissions.

Read why  Kevin Dempsey of American Iron and Steel Institute thinks that America is doing so well with decarbonization.

This article first appeared in Heat Treat Today’s November 2022 Annual Vacuum print edition.

There are several reasons for the American steel industry’s leadership in decarbonization. A key factor is that the American steel industry has adopted electric arc furnace (EAF) technology at a much more accelerated rate than the global industry. Nearly 71% of the steel produced in the U.S. in 2020 was from EAFs, compared to only 26% globally.

In addition, the American steel industry operates blast furnaces that are among the most carbon efficient in the world. Integrated steel mills in the U.S. are almost entirely fed by domestically sourced iron ore pellets compared to CO2 -intensive sintered ore used in China and elsewhere. This results in significantly lower emissions of CO2, as well as lower emissions of NOx, SO2, and particulate matter.

Also, the emissions factors associated with the energy mix used for steelmaking in the United States are lower than in other steel-producing locations in the world, with much more reliance on natural gas and renewable energy. This cleaner energy mix helps produce steel with the lowest CO2 emissions. The American steel industry is continuing to invest in clean energy to provide the electricity needed to run our mills — a number of steel producers in the U.S. have announced several projects that employ renewable energy to supply all or most of specific facilities’ energy requirements.

The steel industry in the U.S. also continues to make other key investments to further decrease its carbon emissions and advance its leadership position on sustainability. For example, American steelmakers have made investments to increase the use of direct reduced iron (DRI) and hot briquetted iron (HBI), which can lower emissions for both integrated blast furnace-basic oxygen furnace steel mills and EAF steel mills. Additionally, new DRI and HBI facilities are being designed and have recently been built to be hydrogen-ready once clean hydrogen is available on an industrial scale and commercially viable.

Steel is a critical component in the continued development of all clean energy technologies to reduce America’s carbon footprint. According to a recent study by McKinsey & Co1, steel is the only material critical to all low-carbon technologies. Wind, solar, and tidal renewable energy systems, zero emission electric vehicles, electric grid transmission, hydrogen production, and carbon capture systems all highly depend on steel. For example, steel comprises over 70% of the weight of a typical wind turbine. Grain oriented electrical steel (GOES) is a critical and irreplaceable material used in the production of power and distribution transformers that will be necessary for the greening and modernization of the domestic electric grid. American non oriented electrical steel (NOES) is used for electric motors, including those that will power the growing electric vehicle market.

The American steel industry and  its construction partners have also proactively and voluntarily published verified Environmental Product Declarations, which report the carbon footprint and other potential environmental impacts for nearly every steel construction product available in the marketplace today. Furthermore, when steel construction products have outlived their current intended use, they can be recycled into new steel to be used for any variety of new products. Today’s steel beam can become tomorrow’s refrigerator, soup can, or car door.

Sustainable steelmaking is the American steel industry’s number one commitment — for our customers and all Americans. Our entire industry is continuing to make key investments and innovations to further decrease carbon emissions and advance our leadership position on sustainability.

About the Author: Kevin Dempsey is the president and chief executive officer of the American Iron and Steel Institute, a leading advocacy group representing electric arc furnace and integrated American steel producers. He previously served as senior vice president of public policy and general counsel to the Institute, during which AISI achieved landmark policy successes on trade, tax, and infrastructure, and successfully showcased the steel industry’s sustainability accomplishments and steel innovations in the automotive and construction markets.

Improving Your Use of Radiant Tubes, Part 2

op-edLast month, we introduced the importance of radiant tubes in the heat treat industry. We explored the “why” of radiant tubes and skimmed the surface, exploring materials, sizing, shapes, longevity, and installation — all topics we’ll deep dive into in future posts. This month, let’s explore what typically occurs inside a radiant tube.

This column is a Combustion Corner feature written by John Clarke, technical director at Helios Electric Corporation, and appeared in Heat Treat Today's December 2022 Medical and Energy print edition.

If you have suggestions for topics you’d like John to explore in future columns, please email Karen@heattreattoday.com.

The radiant tube burner combines fuel and an oxidizer (commonly air) in the presence of a source of ignition. Radiant tube burners differ from burners that are fired into an open furnace. They function to distribute heat as uniformly as possible within the interior of the tube to maximize its temperature and heat transfer uniformity. In some applications, a low rate of heat transfer is acceptable (for example, in the holding zone of a continuous furnace). In that same furnace, a much higher heat transfer rate may be required in the front of the furnace. In all cases, higher heat  transfer rates result in higher internal tube temperatures. In most cases, the higher the temperature, the greater the stress on the material.

Within the radiant tube in the visual flame region, the energy is transferred to the inner surface of the tube by convection and radiation. The rate of convective transfer has much to do with the mixing characteristics of the burner in question. Once combustion is complete, the heated products of combustion — CO2 , O2 , H2O, and N2 — continue to flow through the radiant tube. They impart heat to the interior surface of the radiant tube through convections and — in the case of the CO2 and H2 — radiation. The non-polar gases (O2 and N2) are effectively transparent to radiation: neither absorbing nor radiating heat. This transparency poses a problem for the performance of radiant tubes because the combustion process is ideally complete some distance before the end of the radiant tube.

There are a few ways to make use of the heat stored in the O2 and N2 . One way is to stir the mixtures to ensure these gases meet the inside walls of the tube and can convectively transfer their energy. Another way is to insert a “core buster” or other device into the exit end of the radiant tube. This device must be able to withstand the peak temperature of the products of combustion at this point, so it is typically constructed of some ceramic material or a composite of ceramics. As the heated gases pass over this “core buster,” the resistance forces higher flows around the perimeter of the tube, increasing convective transfer. The “core buster” also is convectively heated and can then radiate heat to the inner surface of the tube and, finally, the “core buster” increases mixing of the gases to ensure all remaining hydrocarbons and carbon monoxide are brought into contact with oxygen to complete the oxidation process.

The transfer of heat to the inner surface is dependent on the effective surface area. A tube with a nominal inside diameter of four inches may have a much greater effective surface area due to roughness, which resemble very small peaks and valleys. Anyone who has attempted to walk around a small Caribbean island can attest — it takes a lot longer than you would think by looking at the map and really scares your shipmates when they cannot find you. Cast and composite radiant tubes can be fabricated to increase this effective internal surface area. Tubing can also be equipped with internal fins.[blocktext align="left"]No matter what the construction, ultimately it does no good to transfer heat to the interior of the radiant tube if the tube cannot transfer the same quantity of heat through the exterior to the furnace and work being heated.[/blocktext]

Which mode of control is better? High/Low, proportional, or pulsed? Any method can achieve a uniform tube heat release given the correct burner radiant tube combination. The important thing is that the vigor of the mixing is matched to the length and roughness of the radiant tube. Burner X may be perfectly suited to a short radiant tube but lead to non-uniform heating as the tube length is extended. On the other hand, Burner Y, with a relatively lazy flame, may work perfectly on long tubes with lower heat transfer demands but be unsuitable for short tubes where high heat transfer rates are desired.

In the coming months, we will examine many of these areas in greater detail, and this author can make use of his experience of many failures to inform the readers of what not to do. Then, by extension, we’ll learn how to get more from the furnaces by thinking systematically about their radiant tubes, burners, and controls.
