2 Large Scale Furnaces for Automotive and Marine Propulsion

Two intensive furnace projects are poised to bring heat treating to the automotive brake rotor and marine propulsion systems industries. An FNC furnace has been completed which will process approximately 600,000 brake rotors per year for the automotive industry. An additional pit nitriding furnace has a capacity of 40,000 lbs and will be utilized for the production of large marine gears.

“In August our Team received Final Acceptance on two of the most difficult projects in Nitrex history…Our most sophisticated brake rotor semi-continuous FNC furnace is installed at a subsidiary of a major auto maker in Europe. Again, our team worked tirelessly to meet customer demands. I am so proud of our team and what they accomplished,” remarked Mark Hemsath, president of Nitrex/UPC Marathon.

The scale of the brake rotor furnace highlights its uniqueness. The furnace processes approximately 600,000 rotors per year, or about 1.6 metric tons per hour. If run continuously, output could approach nearly a million rotors annually.

The brake rotor furnace integrates a post-oxidation (ONC®) process, allowing control over both the color and oxide layer. This feature sets it apart from furnaces currently in use for brake rotors.

The standard load size of the brake rotor furnace is: 1200 mm x 1200 mm x 1800 mm, with a gross load capacity of up to 4 metric tons. Nitrex was able to offer an extended charge size to 2400 mm deep, which could raise throughput to about 2 metric tons per hour.

The pit furnace represented another leap forward with a capacity of 40,000 lbs. — double the weight of Nitrex’s standard largest pit furnace. Engineering efforts centered on maximizing productivity while maintaining the precision nitrided layers expected from smaller systems.

This furnace presented significant logistical challenges due to its sheer size and complexity in transport and installation.

Mark Hemsath remarked: “I am so proud of the effort our entire team exerted to meet schedules, quality demands and design improvements. Our largest ever precision Nitrider (4.5 meter diameter!) for deep-case nitriding of large gears was built on-site with no prior testing.”

The pit furnace is built to handle extremely large gears, typically for marine propulsion systems in very large ships where double-helix gears are standard. These gears, which can weigh 20,000 lbs, require 12 days to nitride, not including heating or cooling — a stark contrast to the two-hour cycle time of the semi-continuous rotor furnace, which is for high volumes in automotive settings.

The furnace stands at 4.5 meters (177 inches / 14.75 feet) in diameter and 3.5 meters deep (11.48 feet), marking one of the largest precision nitriding capacities ever built with a retort lining.

Project Highlights

These projects were collaborative, drawing expertise from across the organization.

In Canada, Janusz Szymborski came out of retirement to contribute design enhancements. Lead Designer Kamil Szczudlo and Chief Engineer Marcin Doroszko from Nitrex’s Poland facility drove the design, automation, and gas flow systems, while plant manager Robert Sokolinski coordinated production and logistics. Karl Michael Winter, vice president of Engineering in Germany, worked on advanced brake rotor layer formation.

Fringe Friday: New Green Steel Technology Transforms Domestic Iron Ore

We’re celebrating getting to the “fringe” of the weekend with a Heat Treat Fringe Friday installment: a project that revolutionizes domestic steel making. Learn more about this green steel tech that plans to turn into a 500,000-tonne per year production micro-mill!

While not exactly heat treat, “Fringe Friday” deals with interesting developments in one of our key markets: aerospace, automotive, medical, energy, or general manufacturing.


Hertha Metals has founded a technology with the potential to transform domestic steelmaking. The company’s proprietary technology is powered by natural gas, hydrogen, and electricity, enabling steel production from any grade of iron ore or waste oxide, in any format, including fines and lumps. Hertha’s process has been demonstrated at a continuous 1 tonne-per-day scale at their Conroe, TX facility, with plans to scale up to 9,000-tonnes, before launching a 500,000-tonne per year micro-mill.

This semi-continuous, single-step process delivers tunable iron and steelmaking. With Flex-HERS™, the proprietary technology, Hertha Metals can tap into domestic iron ore resources and produce low-emission steel using abundant natural gas. As clean hydrogen becomes more available and affordable, they plan to switch fuels — without changing the furnace, to remove the loss of stranded assets, and future-proof a path for steel production.

“After three short years of heads-down building, Hertha Metals is ready to show the world what we have achieved. After more than 300 years of coal-based primary steelmaking, Hertha Metals is introducing a process that is more energy efficient, more cost competitive, and more flexible with feedstock quality.

“The team at Hertha has been hard at work, developing and scaling our single-step ore-to-steelmaking technology. We have demonstrated our technology with various ore qualities and format (including fines) at a scale of 1 tonne per day of continuous clean steel production. This is the largest novel steelmaking pilot plant demonstration in the US and I am so proud of the speed at which we got here,” said CEO and founder,
Laureen Meroueh.

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…

Gas-Fired Car Bottom Furnace for Heat Treatment

A heat treater in the U.S. Midwest anticipates greater heat treat abilities of ingots with a new gas-fired car bottom furnace. The furnace will be capable of handling both steel and aluminum ingots, with loads up to 150,000lb per cycle.

Vice President, Metal Furnaces
NUTEC Bickley

NUTEC Bickley designed the furnace to operate across a wide temperature range. The high levels of temperature uniformity to be delivered by the combustion system mean that this furnace will be qualified to undertake AMS2750 compliant surveys.

Arturo Arechavaleta, NUTEC Bickley’s vice president of Metal Furnaces, said: “Our customer for this important project has been serving the industry with a dedicated heat treat facility for many decades, and is a widely recognized and trusted name in steel and aluminum circles.”

The working dimensions of the furnace are 12ft w. by 35ft l. by 14ft 6in h. Normal operational temperatures range between 300°F (150°C) and 1650°F (900°C), with a maximum of 2000°F (1095°C). With burners firing above and below the load, there are 11 automatic control zones (five top, six bottom). The optimum approach to heat treat these heavy loads is pulse firing with variable excess air.

The furnace uses high-velocity nozzle-mix burners in a staggered configuration to fire above and below the load, maximizing heat transfer and providing optimum temperature uniformity. One of the IMPS® (Integrated Multizone Pulsing System) modes is Excess Air Firing. Among other things, it allows control over very low temperature while high turbulence is maintained to achieve temperature distribution.

In the Ratio Firing mode, the air and gas valves pulse in a synchronized pattern, from low to high fire in stoichiometric ratio, to ensure optimal fuel efficiency. This is made possible by using the kinetic energy generated by the flame speed and the rapid transition from low to high fire which increases entrainment and turbulence, thus promoting a better temperature distribution without the need for a high level of excess air.
