Step Back from the Fire, Caveman, and Think
Heat treatment is a hands-on science and it can be easy to forget about continuing education. In today’s edition of Combustion Corner, Jim Roberts, president of U.S. Ignition, encourages readers to continue cultivating their own heat treat learning and offers specific and practical educational resources to do just that.
This informative piece was first released in Heat Treat Today’s June 2025 Buyers Guide print edition.
So, a furnace guy walks into a heat treating facility and says, “What’s that?”
The Flame and Man
Since the invention of fire, we as upright, walking, opposing-thumb-equipped critters have been learning to control it. We have learned at the elemental level that we can change the properties of just about anything on the planet simply by exposing that item or material to the flames. Certainly, we hold fire as one of our most fascinating benefits of our existence.
Yet, in the grand scheme of things, we are just now really learning to control at levels that our Neanderthal cousins would never have conceived, and they didn’t! Conceive the possibilities, that is. I mean, for the first 400,000 years of our human existence, (that’s a mindblower, isn’t it?), fire had four basic purposes: warmth, light to see in the dark, protection from predators/enemies, and to cook our food. Later, we discovered that by heating up the tip of certain sticks, you could make the stick useful over a longer time. It didn’t wear out as fast. And from there we figured out ways to change other materials at our behest by using the flame. Weapons and tools followed.
In the bigger picture, we only have figured out the really cool uses in the last 5,000 years — and the really, really cool stuff in the last 300 years. So, the learning curve for us has been relatively late when it comes to the heat and the flame and the ability to understand it — to really control it.
Furthering the Science of Heat
How did we get to this stage of significant control over temperatures and systems that would melt a Cro-Magnon’s noodle right there in his big ol’ skull? We used our ever-developing brains. We used intelligence to advance the art of using the flame. Others before us thought their way into our present-day future. Shouldn’t we keep the ball rolling? Isn’t this ever-evolving commitment to responsible use of the flame what we need to do? We accept the gift of those before us and strive to improve on it for the upcoming iterations of humankind. Idealistic? I think not.
The premise of temperature is basically fixed. We can put it in a furnace, we can put it in a vacuum, we can melt the very rocks our planet is made from. So, let’s use the very latest available knowledge to further the science of heat. Let’s improve the situation, both at work and personally, by using our brains and by learning about what is going on with the furnaces, the parts, the fuels, and all the methods of heating. Let’s keep learning about the latest technologies. Let’s actually control this wondrous element.
To do that, we must embrace the knowledge, we have to know what we are looking at. We need to know the history and have a vision for the future. We need to teach and be taught.
Learning the Industry
If you or your reports need to get up to speed with our industry, indeed our very science — GO TO SCHOOL! The fact you are even reading this publication shows that you are open to learning. Let’s ace the test!
Heat Treat Today runs a drink-from-the-firehose learning experience called Heat Treat Boot Camp. You can learn the latest and greatest technologies and new technologies on the horizon in heat treating. Send yourself, send your people.
The Metal Treating Institute (MTI) runs an online certification school that teaches the ins and outs of the heat treating industry. The Industrial Heating Equipment Association (IHEA) runs an annual Combustion Seminar. Almost all the major furnace and equipment suppliers offer seminars on their specialty niche.
Educational Opportunities Include:
- Ipsen Global has “Ipsen U”
- Surface Combustion offers Virtual Learning Applications
- SECO/WARWICK produces a Global Training Seminar on continuous improvement and heat treating
- Can-Eng offers analysis of specific inquiries
- Ajax Tocco will come to your facility to conduct the latest schooling on your equipment
All you must do is decide that you are going to continue to learn more. How can you not with these kinds of services around you?
Don’t forget Safety. National Fire Protection Agency (NFPA) seminars are available from NFPA themselves. Industry experts who have certified trainers, like Rockford Combustion, also offer multi-day seminars on equipment safety.
I can attest to the effectiveness of these kinds of learning commitments. I have been both a student and a teacher at some of the aforementioned seminars. The scope of learning can be broad or focused. It’s up to us to keep mentally expanding, so that the lessons learned don’t get lost, and the future technologies get a fair review.
I have been watching with interest how over the last 25 or so years precise control over combustion has been evolving. The major controls and process monitoring companies have been striving to gain precise control and safety on furnace equipment for years. I might add, they have been successful in varying degrees, and safety and maintenance have improved greatly.
I just spoke recently with a company in Erie, Pennsylvania. They have developed a program that monitors each individual burner. Not only does it tell if the burner is running, but if there has been a component failure, if the burner is out of tune, it can self-correct, and if there is a failure, they shut it off. Oh, and they do that for you, from THEIR office. The technology just grows and grows, doesn’t it?
So, I know some of you were wondering where I was going with the Caveman intro, and some of you probably would have preferred that I kept going up to the point where we were cooking mammoth steaks on sizzling rocks with our Cro-Magnon buddy. But we are better than him, and we need to keep proving that. Don’t you think?
Besides, this is the final month before school is out for the summer. Let’s give education a nod here.
I am sorry if I did not mention your company, no slight intended. If so, contact your customer base to alert them to any learning experiences that may be available.
Keep learning. Until next time…
