Łukasiewicz – the Institute of Non-Ferrous Metals (Łukasiewicz – IMN) recently expanded its heat treating operations with a VIM furnace for melting metals and metal alloys on a laboratory scale. The new equipment will be used to develop new types of alloys, make individual castings, and conduct research on melting processes.
The vacuum induction melting furnace, ordered from SECO/WARWICK, has a maximum operating temperature of 2000˚C (3,632°F) and a single-chamber VIM furnace. It was designed to produce metal and alloy castings weighing up to 20 kg in vacuum, or under pressure using an inert gas (argon).

This is the second processing solution the furnace supplier has designed for the institute. Łukasiewicz – IMN, a member of the Łukasiewicz Research Network, received a targeted subsidy for the implementation of an investment related to scientific activities for the purchase of research equipment granted by the Ministry of Education and Science (currently the Ministry of Science and Higher Education).
“Scientific institutions are one of the group of recipients for our solutions,” said Sławomir Woźniak, CEO of the SECO/WARWICK Group. “For example, we have supplied solutions to the Karlsruhe Institute of Technology (KIT), which ordered a non-standard, 12-meter vertical rotary retort furnace for the heat treatment of a gyrotron part, as a contribution to the ITER experimental thermonuclear reactor. We have also supplied laboratory furnaces for the Institute of Precision Mechanics. We invest heavily in research and development ourselves. We have our own R&D centers, which allow us to continuously improve the technology we offer.”

Heat treat industry players from across a spectrum of facilities, suppliers, and manufacturing specialties landed in Pittsburgh, Pennsylvania, on Monday, September 24, 2024, to kick off Heat Treat Boot Camp 2024. Attendees networked, gained new practical knowledge, and participated in a tour of a local commercial heat treating facility. It wasn’t all work; an opportunity to get to know one another at a meet-and-greet reception upon arrival and later on a trip up Pittsburgh’s Duquesne Incline allowed boot campers to relax and connect, balancing work with fun.
A day and a half of sessions led by instructors Doug Glenn, publisher and founder of Heat Treat Today, and Thomas Wingens, president/CEO and founder of WINGENS International Industry Consultancy, brought the 39 trainees up-to-speed on “Processes & Materials,” “Heat Treat Players,” “Latest Heat Treat Developments,” and more. Questions and discussion were encouraged during the formal sessions, and heat treaters had plenty of informal, additional learning time through interactions with each other and the instructors.
At the end of the first day of lectures, nearly all of the attendees boarded a school bus to visit the Duquesne Incline on Mount Washington and enjoy the view of Pittsburgh. Following another day packed with training and resources, attendees had the option to visit Solar Atmospheres in Hermitage, Pennsylvania, to tour the in-house vacuum heat treating and brazing facility.

“I’ve enjoyed talking about the different types of heat processes and the types of furnaces — vacuum and atmosphere air systems,” said Ike Okoh, a product engineer with Dry Coolers, Inc, based in Michigan. “The questions I had before the course started were answered during the course, and the most beautiful part of the program was that it’s not always you get to see CEOs and or business owners in the training sessions with you. It’s wonderful to get to meet them and find out more about them and their companies.
“The instructors, Doug and Thomas, were really nice, went through the course and broke down some of the issues, took questions and answered them,” Okoh added. “All in all, it’s been an enlightening experience.”
“Every group that’s been here is different,” said Glenn. “This group has been really fantastic; it’s an engaging group, and overall, we’ve heard positive feedback that the sessions and networking have been helpful. So, thanks to everyone who has come, and we look forward to seeing others next year.”

No matter the craft, disappointment is inevitable when the end result doesn’t turn out as planned. But in heat treatment, distortion is more than just a disappointment, it could contribute to weakness in a component, putting lives at risk. The industry can be credited for its commitment to determining the causes and manners in which parts distort and how to eliminate the risk.
Today’s best of the web article examines the inevitability of distortion in heat treating and demonstrates how to predict changes in size and shape of parts during processing, acknowledging that “maintaining dimensional accuracy is essential, especially for mission-critical and safety-critical components with the tightest tolerances.”
An Excerpt:
“Every part you heat treat will have some degree of ‘ballooning’ and distortion, but there are ways to predict how much your parts will deform. Knowing how your parts will change during heat treatment allows you to account for that change in the design of the part and, in a perfect world, avoid an additional round of machining after heat treatment.”

Like most power systems, power control dates back to vacuum tube technology. Like radios, amplifiers, and other industrial equipment, the furnace market started using transistors as the technology evolved. Vacuum tubes were not generally balanced and contained poisonous elements and were phased out of usage in almost all industries. In this Technical Tuesday installment, guest columnist Stanley Rutkowski III, senior applications engineer at RoMan Manufacturing, Inc., distinguishes the different methods used to regulate power input to furnaces.
This informative piece was first released in Heat Treat Today’s August 2024 Automotive print edition.

In today’s furnace market, there are generally three primary types of control systems: VRT, SCR, and IGBT. Each of these control technologies employs different methods to regulate the power input to the furnace, which in turn generates the required heat. These control systems transfer the power from the plant power system to a transformer in line with the load (heating elements). Power is delivered to a plant in a three-phase system from the utility company. The least costly and highest power factor systems have a balanced load across the three phases during the operation of any furnace.
A VRT incorporates a feedback mechanism to either increase or decrease the amount of DC injected into the controlling reactor in the system. This increases or decreases the amount of current in the system to control the heat in the furnace by comparing it to the scheduled setpoint. A VRT system can have the following configurations:
An SCR control system uses a pair of thyristors (gated diodes) to control the amount of power applied to the primary of a transformer. The SCR control delays the start of the waveform, and the control point is reset when the waveform crosses the zero line. An SCR system can have the following configurations:

An IGBT uses a diode bridge, capacitor, and switching transistors to control the amount of power applied to the primary of a transformer. The input frequency to the transformer is controlled by the switching transistors. The diode bridge is connected to the three-phase system allowing single, Scott-T (two zone), or three zone systems all to pull a balanced load across the three phases of the plant power system. A line reactor is incorporated to maximize the power factor in the system, minimizing the total power usage of the furnace. The IGBT system also uses a square wave into the transformer and a rectifier after the transformer to remove inductance out of the power delivery system to reduce costs of cables, breakers, and other components in the total package.

Stanley F. Rutkowski III is the senior applications engineer at RoMan Manufacturing, Inc., working on electrical energy savings in resistance heating applications. Stanley has worked at the company for 33 years with experience in welding, glass and furnace industries from R&D, design, and application standpoints. For more than 15 years, his focus has been on energy savings applications in industrial heating applications.

Heat Treat Today publishes eight print magazines a year, and included in each is a letter from the editor, Bethany Leone. In this letter, Bethany reviews the recent dip in enthusiasm about electric vehicles (EVs) and raises some questions about what this means for the future of the industry. This letter first appeared in the August 2024 Automotive print edition.
Feel free to contact Bethany at bethany@heattreattoday.com if you have a question or comment.
How much do you care about whether or not electric vehicles (EVs) are being manufactured?
I have a family member who loves his Tesla. Honestly, it’s quite epic. The engineering is seamless; the ride is smooth. Out west, the incentives to buy, paired with the warm climate, made it a sensible move. Top it off with an at-home charging station and plenty of access to compatible charging stations in his city, and you’ve got it made.
The constant stream of new information about electric vehicles brings a juxtaposed vision of amazing technological realities alongside stubborn supply chain and infrastructure mishaps.
In Q4 2023, demand reached an all-time high, with 8.1% of all new vehicle purchases being EVs. Yet 2024 has seen turbulent lows (Q4 2024 market share lower than Q1 2020) and Hertz being caught $750 million in debt after a failed EV integration strategy. This has since tapered, though interest in hybrid grows rapidly.
With the narrow adoption of EVs, as well as the uncertain projections of the automotive industry based on Tesla’s movements, the impetus to learn more about heat treating components for this new technology may feel . . . less than imperative.
But there are two realities to consider.

Uncertainties abound with any new technology, especially one that carries the burden of contributing to decreasing carbon emissions. (At the current rate, sales will not allow the market to reach the Biden administration’s 50% EV sales goal by the 2030 target.)
EVs are losing traction in market demand: The excitement from early wave adopters seems to have come to an end. The long-anticipated second wave of users from the middle class may not happen this year. And grumblings about range anxiety, long charge time, high insurance and repair costs, and battery efficiency in cold weather environments continue to keep customers from the lot.
The biggest burden nationwide has been limited access to reliable charger ports, especially for non-Tesla drivers. The WSJ covered this problem in an LA case report, noting that almost half of non-Tesla chargers had one of these top three issues:
In the U.S., nearly half (46%) of current EV owners are likely to switch back to ICE, McKinsey & Company reported in June 2024. The culprits ranked by the full global set of responders indicated the following reasons for their hesitation.

But to be fair, these are growing pain problems. The issue of access to charging stations is set to be alleviated within the next year as major EV automakers adapt to shared charging station technology. Car manufacturers including Audi, BMW, Ford, and GM signed an agreement that will allow their EV models to use the NACS charging stations developed by Tesla.
For dense, old cities where there is no room for a personal garage at the home and parking is first come, first serve — this is coming from someone who lives and drives in Pittsburgh — at-home charging solutions will need to be created, but it’s not impossible.
And the issue of clean electrification infrastructure, cost, and recycling batteries continues to be discussed, to varying degrees of success. So, while the reality is that EV sales are slowing, this is likely the natural lag before further improvements and a second wave adoption.
While going electric in your in-house heat treat operations may have you looking to integrate induction hardening for your gears and valves, the future of EV does not seem to impact the value of significant skills your department needs to learn across automotive heat treat. “When it comes to heat treating,” writes Rob Simmons, metallurgical engineering manager at Paulo, “innovations are rarely exclusive to EVs.” (Read his full article about processes and components here.)
It’s encouraging. We will still brace for change across the automotive industry because of new demands from the EV sector. Despite slowing demand, the increasing attention on hybrid vehicles will certainly keep us busy making vehicles lighter, more durable, and more efficient.
