A special report from Heat Treat Today publisher, Doug Glenn.
Chad Spore, materials engineering supervisor for John Deere, addressed the assembled guests of the International ThermProcess Summit, in Buckhead, Georgia, on the first day of the event, Tuesday, July 31, 2018. The presentation, which included encouragements to other manufacturers with in-house heat treating as well as industry suppliers to continue to innovate, was received with great interest by the nearly 100 attendees at this 2nd biennial event.
The attendees also enjoyed an excellent presentation from Omar Nashashibi. Mr. Nashashibi, as a-politically as possible, presented an excellent perspective on the first years of the Trump Administration. Whether you like Trump or not, Mr. Nashashibi made it clear that Trump was doing something that no other president has done in quite some time — he’s fulfilling all of his campaign promises to one degree or another. It was a balanced presentation with many positives and negatives.
The two-day event concludes today with keynote speaker and event emcee, Dr. Amber Selking of the Selking Performance Group, giving a presentation on “Driving Consistent Performance Excellence.”
A leading global iron ore and HBI producer and supplier, as well as a producer of high-quality steel, recently launched heat treatment systems with advanced technology for a Russian steelmaking and metal rolling company.
Metalloinvest, based in Moscow, installed the Roller Hearth Heat Treatment Furnace #1 and Rolling Quenching Machine #1 at Ural Steel. Mosgipromez provided the design and engineering work for the new facility, while Tenova LOI Thermprocess was responsible for equipment delivery.
The installation of Roller Hearth Heat Treatment Furnace #1 and Rolling Quenching Machine #1 at Sheet Rolling Facility #1 enables Ural Steel to increase the production capacity of the heat treatment furnace from 28.6 to 30.7 tonnes per hour. Over the next 10 years, between 2019-2028, Ural Steel will be able to increase the production of heat-treated heavy plate by three times, and the output of steel for bridge construction by 39%. Production volumes will increase due to the introduction of a new product variety, which will be developed at the heat treatment facility.
Roller Hearth Heat Treatment Furnace #1 and Rolling Quenching Machine #1 will also help to improve the characteristics of the heavy plate, ensuring the physical uniformity of the rolled steel products following heat treatment, by improving heating and cooling conditions.
“The project has been completed as part of Metalloinvest’s comprehensive investment programme to reorganize production processes at Ural Steel, which will boost the operational and management efficiency of the enterprise,” said Andrey Varichev, CEO, Management Company Metalloinvest. “This new high-tech facility will strengthen the Company’s position in the market for heat-treated rolled products.”
“Metalloinvest is a special client for Tenova, to whom we supply our full range of products and technological solutions,” said Andrea Lovato, CEO, Tenova. “Taking part in the reorganization and modernization of Ural Steel’s production processes is a great opportunity for us, and we are confident that our partnership with Metalloinvest will help the enterprise to progress its development even further.”
This project follows Metalloinvest’s recent agreement to build a heat treatment facility for hot-rolled steel at the OEMK’s finishing plant #2, which will include the construction of a building for the heat-treatment facility and two thermal furnaces, and the creation of heavy-lifting and transmission equipment, as well as associated infrastructure. The first furnace is planned to be launched in 2019, and the second will begin operations in 2020.
The new facility will enable OEMK to carry out various kinds of heat treatment from 750-1800°F (400-980°C), a wide range of temperatures, in order to produce high-quality rolled steel products with a specific microstructure. Heat treatment is required in the production of various kinds of steel for springs, ball and roller bearings and construction, as well as for high-strength metal.
Varichev said: “We are seeing a high level of demand among customers for high-quality bars, which require heat treatment. Creating this new production facility will enable Metalloinvest to increase sales volume of this premium product and reinforce its position on the SBQ market.”
Heat treating thermocouples are thermal processing sensors that allow equipment operators to accurately measure and maintain the right temperatures for softening, hardening, and material modification. A faulty thermocouple can result in inaccurate measurements, so it’s critical for quality management personnel to determine when and why thermocouple failure has occurred. GeoCorp, Inc., has provided a series of short articles that walk operators through assessment and troubleshooting of thermocouples that go bad.
Sometimes the smallest issues can lead to big problems. When your business relies on crucial temperature readings from your thermocouples, it can pay to pay identify individual factors that may have cause part failure. ~ James LaFollette, GeoCorp, Inc.
When troubleshooting thermocouple failure, the authors, James LaFollette and John Ochenas, recommend reviewing three key issues: system wiring, probes, and wire and junction. In addition, the following could cause misreadings:
A Cincinnati-based heat treat technology solutions provider recently completed a controls and software upgrade for the bearings brand of an engineering and manufacturing group at the latter’s facility in Dahlonega, Georgia, including instrumentation and software for hardening furnaces, quench, washer/rinse, and temper equipment.
Super Systems Inc. and JTEKT Corporation’s Koyo Bearings brand announced that the scope of the upgrade includes all engineering, installation, controls, and software for Koyo’s gas-fired hardening furnace line. The new automation included a turnkey retrofit of new control cabinets as well as software necessary for furnace control and historical process data review. The controls and software provide JTEKT with the confidence to heat treat parts to meet the highest standards with complete traceability for its Koyo brand bearings.
“We have been fortunate to work with JTEKT on a number of automation projects over the years and we are looking forward to participating in more innovative heat treating opportunities in the Dahlonega facility,” says Bob Fincken, Super Systems National Sales Manager.
“SSi’s ability to understand our needs and provide customized solutions has been a tremendous benefit to us,” says Michael Rebula, Heat Treat Supervisor at JTEKT.
When steel needs to be softened to alter ductility, toughness, or properties, or to produce a specific microstructure, a heat treater can turn to any one or combination of processes to suit the material or the application.
Metlab Heat Treat’s primer series includes a short explanation of the options available, whether it is
annealing, which “removes the internal stresses, which build up as a result of cold working and other fabrication processes;”
protective atmosphere normalizing, which “refines the grain size and enhances the uniformity of the microstructure;” or
spheroidize annealing, which “is generally done on parts which have been work hardened, to allow them to be further worked, either rolled in the case of coils, or drawn for wire.”
A California-based, full-service brazing and heat treating company recently installed several pieces of equipment, including an indirect temper furnace as well as a generator that has clocked less downtime than the previous unit.
ThermoFusion’s investment of the 2200 Tru-Mix Generator and indirect temper furnace, both McLaughlin Services products, are part of the company’s commitment to support customers in the automotive, aerospace, medical, and energy industries, as well as for multiple other application.
The Tru-Mix 220 is supporting two of ThermoFusion’s internal quench furnaces and a high-temperature tool furnace, almost twice as much equipment as the generator it replaced. According to Glen Ottinger, president of ThermoFusion, the results were better than he had anticipated when researching the 2200 Tru-Mix and other gas generators.
The McLaughlin Indirect Temper Furnace was fully functional and ready for operations only two days after arrival, according to Nick Schreiber, quality manager at ThermoFusion, and has been surveyed at +/- 10F or less, between 300ºF and 1400ºF.

Transcript: John Vanas on SX Oil Lifters
The following transcript has been edited for your reading enjoyment.
If you’re a manufacturer and you use parts washers to remove oil residue from metal parts as part of your manufacturing process, or if you’re a commercial heat treater who washes parts, today’s Heat Treat Radio episode should be especially interesting to you. Why? If you thought there was nothing new in the parts washing arena, you’ll be shocked at what you’ll learn today. Let me whet your appetite. What if I told you there is a parts washing additive out there where you only had to add .3 ounces — that’s right, .3 ounces — to every gallon of wash water? And what if I told you that you could run that solution for 3 to 4 months without adding any chemicals? And what would you say if I told you that the oil skimmed off of your wash bath would have a lower water content than anything that you’re currently using? And what would you say if I told you your maintenance team would never have to check the concentrations of your wash water again? Not enough? Okay, let me give you one more. What if I told you that when you were done with the bath, you could just dump it down the drain? Sounds too good to be true, right? Well, buckle up, because Heat Treat Today is going to take you where no heat treat washing system has ever gone before.
For today’s episode of Heat Treat Radio, your host, that’s me, Doug Glenn (I’m also the publisher of Heat Treat Today, which you can find on the web at www.heattreattoday.com), took a road trip to Euclid, Ohio, to visit with a current user of the wonder wash additive I just described to you. It was a rainy day, so any raindrop noises you hear are, in fact, raindrops.
John Vanas (JV): This is our rotary retort building.
Doug Glenn (DG): Ok, great.
JV: And this is Euclid Heat Treating Company. I am John Vanas. It was established in 1946 by my father. So we have been around for 72 years.
DG: 72?
JV: 72 years. I have been here 46 years.
DG: And it is a family business, right?
JV: Yes, a family business. I have got three kids working here and we are probably the most diverse commercial heat treater in this area. We do a lot of different things: induction, rotary retort, batch, pit, nitriding, ferritic nitrocarburizing, and intensive quenching. We have got quite a bit of different processes that we do.
John and I are on a walking tour of his six-building commercial heat treat complex just northeast of Cleveland, Ohio. As he mentioned, Euclid Heat Treat Company is no fly-by-night establishment. John’s dad started the business and has passed it down to John who is well on his way to passing it on to his kids. Before we jump into the specifics of the “wonder wash” additive, which by the way, is not the name of the product — it is called SX Oil Lifter — but before we jump into the specifics of that additive, here is a bit more about the family business.
DG: So you got it from your dad?
JV: Yes.
DG: Roughly, when?
JV: Actually he passed in 1991. I have been running it since 1974. We had a general manager who ran the plant and he passed away, so they threw it to me. I was here for two years and my dad said, “It’s your baby. I am going to Florida.” So, that’s alright.
DG: And you have three kids?
JV: Three kids.
DG: Which are Deidre, John ….
JV: ….. and Claudine. They work here. John runs production, Deidre is going to be the General Manager, pretty much, and Claudine does the finance work. And I just try to keep everybody in line.
The Plant Floor: Where the Magic Happens
John and I were standing at the entrance of his rotary retort building, as I mentioned, one of the six buildings, located just off of 222nd Street in Euclid. As we were working our way to washer end of one of his rotary retort furnace lines, John explained the markets he serves with these furnaces.
JV: Two rotaries we’ve got an AGF 139 and an 1814, so this is a large retort that quenches into polymer and this one quenches into oil and goes right through the wash and out the other end to the finished product. Not too many people do rotary work anymore. There are a few of us around, but the beauty of this is the parts tumble and they get even case all over where with a belt furnace they mask each other by laying on each other, so it’s a good technology. Kind of a niche market for us.
DG: So it’s primarily fasteners?
JV: Fasteners, little stampings, just a little bit of everything. You can see here these are actually plugs for automobile and truck oil pans. We do a ton of these things. There’s a little stamping here that we’re running. You name it, if you have to have even case hardness we can do it in these two furnaces.
We then moved our way to the discharge shoot at the back end of the first rotary retort furnace where parts fell into an oil quench and then on into a spray washer. John wanted me to see that the oil being pulled out of the washing solution was almost 100% pure oil; very little, if any water. Here’s how John tells it:
JV: So we load through the retort into the oil quench then into a wash. This is a spray washer. Then we’ve got one of these hula hoop type tooth skimmers that skim the oil off into this drum. If you can see that; that’s almost pure oil. This is the XS Oil Lifter in here. But that’s almost pure oil. There is no water in there.
We spent a few more minutes discussing John’s rotary retort lines and the washers associated with it, including a disc skimmer and another bucket of, as John describes it, “pure oil — there’s no water in there.” The point being, there is a cost savings when you send this oil out to be processed since there is very little water in the oil.
We next walked by Euclid’s intensive quench system which is essentially an IQ furnace sitting on top of an 11,000-gallon quench tank. Euclid’s intensive quench capabilities is another unique offering for the company.
From Skepticism to New Product Line
After leaving the intensive quench and rotary retort building, we got into the meat of our conversation as we walked in the rain between buildings. The wonder-wash additive which I mentioned, called SX Oil Lifter, I asked John to tell me a bit more about that product.
DG: So John, one of the reasons I came over is we want to talk about this SX Oil Lifter.
JV: Yes, this is a new product that was introduced to me, and I tried it just on a whim because I didn’t think it was going to work in a small wash that we’re going to see over here in one of our other buildings. And it worked so well, I’ve got it now in six washers.
DG: Maybe before we go back into the noise of the building, it was introduced to you by whom?
JV: Actually by a friend of Bill Lohn, he’s my partner. So we decided to give it a try. I put it in a washer and it worked so well that we put it in other washers. It lasts 3 to 4 months and then you change it. You never have to add anything to it, which is the beauty of it. And it just does a great job. So after 3 to 4 months, usually you get oil in the washer and up on the walls of the washer. It just gets kind of scummy. We’ve had some people use it and not change it for 6 months. It just depends on what you’re washing and how often you’re washing.
DG: Now, Bill found out about from who?
JV: He found out about it from a friend of his that was using it for another type of washing and they had initially had developed through industrial but no one was using it for that, so we negotiated with the company to get the license to do it by industrial type of washing. So now we’re the partners and we’re really the company for the industrial side. We’re trying to introduce it to the heat treating industry because once you try it, you’re going to like it.
Nano-Invasive Technology
DG: So just to be clear on it, it’s not a washer, it’s a chemical, but it’s not a chemical-chemical. It’s very biodegradable….
JV: It’s biodegradable. You can probably drink it. When you’re done with it, you can just put it down the drain. If you have oil that you haven’t skimmed off, you can let it settle out and drain it off that way, but most people just dump it right down the drain. There is nothing biologically harmful about it. There is nothing to harm the sewer. Our people test our sewers once a month here and they have found nothing. So that’s how we dispose of it, we just dump it down the drain.
DG: You were also mentioning about the quantity that you have to put in.
JV: Yes, it’s 3/10ths of a percent per gallon.
DG: So for a typical quench tank, what do you put in?
JV: Well this quench tank here has 750 gallons and I think we’re putting 80 ounces in there.
DG: And that 80 ounces will last you for 3 to 4 months, and maybe longer.
JV: Yes, then when you’re done, you dump it down the drain, clean it out and redo it.
DG: Ok, one other thing I wanted to ask. You said they call it “nano-invasive technology”?
JV: Yes, nano-invasive technology. What we found out is it does not actually dissolve in the water like your Tide or some other detergent or Simple Green. So, it’s in there and it’s lifting the oil, but it’s not dissolved in there, so when you’re dumping the fluid, you’re not dumping a dissolved chemical. And the fact that it is not dissolved, you don’t pull off that chemical you don’t have to add. You add water through your float valve, but you won’t add more product. The water evaporates, the product does not.
Seeing the Wonder Wash in Action
From there we went into the big batch building where three Super Allcases (a product of Surface Combustion) were located along with an older Lindberg IQ and a number of temper furnaces.
John showed me a batch wash that had just had the fluid changed the weekend prior, after 3 to 4 months of use. According to John, they probably could have gone longer, but that is the interval his maintenance team established to clean and change out the washing fluid. All the maintenance team did was wash down the inside of the washer and remove all the oil residue, skim off the oil from the top of the bath, and then dump the wash fluid down the drain. That’s it.
From the big batch building, we moved on to induction building.
JV: We have different stations and different power sources. We probably have about a dozen power sources and probably 40 different stations for doing different things. We’ve got a bolt machine there that he’s working on. We have a rotating machine there for different gears. We do a little bit of everything in here. We’ve got it crammed into the building pretty good. We just had this mezzanine put in and put the power sources up on top.
John’s father started the induction division. It was one of his special interests. John indicated that Euclid does a lot of work with local induction genius, as John describes him, Bill Stuehr of Induction Tooling out of North Royalton, Ohio, not far from Euclid.
The last building we entered was the vacuum and pit building.
JV: Here we have our vacuum equipment, our pit furnace, and our little batch furnace.
This building had about a dozen different vacuum and pit furnaces. After hitting this last building, we went back to talking a bit more about SX Oil Lifter and especially on the cost savings.
Pouring Savings into the Tank Instead of Down the Drain
DG: I assume there are cost savings here, right?
JV: Yes, it’s going to be about a third of what most people are using, from what we can determine. At least from what we used to use. We used to use a product from one of our oil suppliers and it would kinda make a funny-looking emulsion on the surface. And when we skimmed it off, we’d have to put it in the tank, let it settle out, drain it off until we got down to the oil and take the oil out. But we found out that we were getting a pretty good percentage of water in the oil when we sent it to the recycler. So he would charge us for getting the water out.
DG: So when you changed over the oil lifter, you didn’t have any problem with your current equipment that you used to separate the oil out I assume, right? There was no adverse effect?
JV: No, it was the same skimmer we always used, but it was just much more efficient.
DG: And you’re getting much better purity?
JV: Yes, we’re pretty much getting all oil in the tanks from the skimmers instead of an all water mixture.
When we walked back outside and headed back to John’s office, I asked him to repeat the cost savings information.
JV: It looks like from what we’ve seen from what our products we used to use, it’s going to be about a third.
DG: So you’re saving two-thirds?
JV: Yes. Plus, again, the beauty is, you don’t have to add all the time. You don’t have to have somebody coming in titrating. You can’t titrate this stuff. You can’t figure out what the percentage is because it’s such a small percentage, it doesn’t show up. We’ve tried several different methods to try to determine if we’ve got the right mix still in the tank, but we’ve come to the conclusion that you can’t. So, you put it in, you use it for 4 months or 3 months. When it starts to get to the point where perhaps it’s not cleaning the oil off well enough, you dump it and refill it.
DG: And you judge that not by taking any chemical composition of the solution, you just watch the parts, and if you’re seeing oil residue, it’s time to change.
JV: Exactly. And that kinda flies in the face of someone with technical knowledge, but that’s the way it works. You can tell if you’re washing off quench oil, if you start getting a smokey temper load, obviously you’ve got too much oil in there.
Once we got back to John’s office, I pressed him even more on the cost savings.
JV: We know the product we were using before was pretty expensive and I’ve talked to people who have tried and it and they said we’re putting a 55-gallon drum a month into our washer of the product we’re using now. And I said, well you won’t be doing that with SX Oil and I know that stuff is pretty expensive.
We further quantified the savings by talking about the money saved on oil processing because of less or no water in the oil being processed, plus the time savings of not having to test concentration levels of the wash. John had more to say about the time savings.
JV: Just talking to some other people who have tried the product, they said we’re going to save a lot of money because we have a guy who has to titrate it, has to add to it, and we don’t have to do that anymore.
DG: And they’re paying for that, I assume. They’re paying for that service or they’re paying one of their employees.
JV: Usually one of their employees. But it’s time-consuming and it’s a lab situation and titration. And with this, you don’t have to do anything.
I asked him if he had ever run into any problems with the product. He said that one customer called complaining the parts washed in the product were rusting faster than normal. After John and his fellow user discussed it for a while, they concluded that the product was doing such a good job of removing the oil from the surface, that it was more prone to rusting. What was the solution? John is working on adding a rust preventative to the product to help minimize the issue.
If it sounds too good to be true, it’s not. Here’s a brand new product. In fact, a brand new nanotechnology product, that
requires only .3 ounces per gallon of water,
lasts for 3-4 months minimum depending on your workload and oiliness of your products,
results in an almost pure oil skimming which minimizes oil reprocessing fees,
frees up your maintenance team to do other things besides worry about the washer,
and best of all, when you’re done, dump it down the drain.

A new vacuum furnace will be tasked to stress test parts for the LM2500 turbine, which is used by the U.S. Navy to power Spruance and Kidd-class destroyers, Olive Hazard Perry-class frigates, Ticonderoga-class cruisers, and Arleigh Burke-class destroyers.
Fleet Readiness Center Southwest (FRCSW) commissioned the $1.9 million furnace from SECO/Warwick Group, which manufactured the 2,800°F unit to specification for technicians to test the engine’s components after the heat treat process. It will not be used for the heat treating or plating of LM2500 parts.
“The furnace was custom made for our use and took almost a year to manufacture,” said Martha Hoffman, project manager for FRCSW’s Capital Investment Program (CIP), which invests in new technologies and equipment to improve production efficiencies. “The equipment arrived May 15, and the sign off (acceptance) was July 2.”
The new unit replaces a model that was more than 50 years old with a four-year history of sporadic operation. Difficulty in maintenance and increasingly obsolete replacement parts often resulted in a 60-80 percent down time, causing some LM2500 work to be contracted out.
Hoffman said that the new unit will save the command about six months in turn-around time per part vice contracted workload and that 12-15 components will be tested weekly.
FRCSW is scheduled to overhaul about 15 LM2500 engines annually.

It’s no secret to heat treaters that not all methods work well on all parts and specifications. It’s also a hard fact that false readings can result when applying hardness measuring systems, therefore, says Charles D. Schulz of Gear Technology, “critical service parts often require a few ‘sacrificial lambs’ to be processed along with the production parts.”
“I cannot emphasize enough that if you are not cutting up parts or coupons you do not know what is really happening during your thermal processing.” — Charles D. Schulz
A manufacturing company based in Loves Park, Illinois, recently purchased a vacuum furnace with 2 bar gas quenching that will be used at its facility in Ho Chi Minh City, Vietnam.
Zenith Cutter, which manufactures industrial knives, cutter blades and related accessories for multiple applications, is transitioning its shop from atmosphere heat treating to using vacuum equipment for production and commissioned a TITAN® H6 furnace from vacuum furnace maker Ipsen for its Metkraft location.
The TITAN® H6 furnace has a graphite work zone measuring a 36″ x 48″ x 36″ (915 mm x 1,220 mm x 915 mm) with a 3,000-pound (1,360 kg) load capacity and is capable of operating at temperatures of 1,000 °F to 2,400 °F (538 °C to 1,315 °C) with ±10 °F (±6 °C) temperature uniformity.
