Jörn can you please tell us a little bit about yourself? For instance; your background, how you first got involved in the heat treating industry and how you came to become the President of Rohde Gmbh?
“I have been working with my father in the company since I was a child. My tasks have grown over the years. It started as a child with sweeping the yard, cleaning machines, helper work and with the start of my apprenticeship as an industrial mechanic (in another company) I could already work independently on furnaces in production and go on assemblies during my vacation. During my studies I was able to enter the design department and later, with my degree as a Diplom Ingenieur (graduate engineer in mechanical engineering), I was able to take over the management of this department. Later I became the managing director of the company. I can say that I have been building furnaces for 35 years and that I am now in my mid-forties.”
I know Rohde GmbH has grown quite a bit over the years. Can you share with us the size of the company, how many employees you have, and annual sales?
“We are a classic medium-sized family business. We employ 25 people and have an annual turnover of approx. 4 million euros. Our ambition is not to grow at any price and employ more people, but to keep improving our equipment and to offer our customers the best solutions worldwide with our long-established team of employees. We want to remain a family business and hope our two sons will follow the tradition and continue the company.”
What products do you have to offer and if you don’t mind me asking what product is your number one seller?
“We supply retort furnaces in various designs. Shaft furnaces, chamber furnaces, bell furnaces and our favorite, special designs. We love the challenge and new customized developments are definitely one of our strengths. Our best seller, however, is our SRU (Salt Recovery Units). These were designed by my father, a design which we continue to upgrade and we have these systems installed around the world.“
I know you have been quite successful with your line of vacuum nitriding systems, please share some details with our readers.
“We are an absolute premium manufacturer in the field. This applies to all important areas of furnace technology: lowest temperature differences, best gas distribution in the work zone, low wear due to best components also for purchased parts. We are also the market leader in energy savings. In Germany, we can undercut our market competitors in terms of price after only three years of use. After less than 15 years, the investment is recouped through the energy savings. Germany is certainly a special case due to the high energy costs, but anyone who values sustainability cannot ignore us. Direct comparisons to other market companions from Germany show that our furnaces are the most energy efficient in the market. We also have strong partners in the field of process development, such as the Leibnitz Institute in Bremen, with whom we always develop state of the technology through various research projects.”
I’m sure you have built a lot of highly specialized furnaces over the years. What’s the most interesting furnace project you’ve worked on?
“Due to the custom designed furnaces we manufacture, it is really not an easy question, as many of the furnaces were special. There is a smaller system that had to fit into a freight elevator in China including all aggregates, because we could not enter the country due to the entry regulations. Or for example plants like our Bell hardening center which hardens fully automatically and quenches in oil or salt. At the moment, special systems for catalysts for hydrogen production are a new task for us, because the product in the furnace has other properties as known. As a graduate engineer, I look for the technical challenge. The higher the demand of the customer, the more fun we have solving the challenge.”
“Yes, no one else wanted to or could build this furnace and we took on the challenge. This project was very exciting. No one had ever built a retort with a diameter of 5.5 meters (16.5’) before. As far as I know, such large furnaces were always built without a retort. We love the challenge! (Editors note; This furnace is located at commercial heat treater “Reese” in Germany and is very impressive).”
There’s a rumor floating around that you are partnering up with McLaughlin Furnace Group to provide Salt Recovery Units (SRU’s) in North America. Can you tell us a little more about the partnership and about Salt Recovery Units (SRU’s) in general?
“We have a good product and Jeff has a great company and can respond quickly in North America. I think in terms of product, quality and service, we have the same high standards. It is easy to find a salesman in any country, but in my opinion you need more. The SRU business in North America is doing well, but by building in North America we will be able to save on the transportation costs and long delivery times. Together we can simply achieve more. In the same way, we will support the McLaughlin Furnace Group in Europe. We can both benefit from sharing our existing resources and I look forward to working with McLaughlin.”
“The more salt a customer buys, the more sense an SRU makes, regardless of the furnace type.
Basically, in continuous furnaces with small parts and high surface area, the salt discharge from the quench tank is the highest. Thus, continuous flow furnaces with salt quenching are ideal for using an SRU.
The function is simple: We continuously remove water from the wash tank. In the SRU, the wash water is evaporated, the salt is separated from the carbonates and impurities, and the pure, liquid salt is added back to the quench tank either directly or solidified into salt blocks. Depending on the carbonate content of the salt, these must be removed from the unit. Initially, this is done relatively often in the salt bath until the salt returns to its original quality. But the loss of salt is significantly reduced and the quality of the product increases! The product is good for the environment, but even better for the wallet.”
We all know how much heat treaters hate ongoing maintenance when it comes to their furnaces, what’s the maintenance like for an SRU?
“Our customers need to clean the plate pack in which the contaminants settle. Turn off the unit, wait until it is cold enough to work safely, remove the plate pack and remove contaminants, then reinsert the affected plates and turn it on! That’s it. Changing gaskets, thermocouples or heating elements happens every few years. So maintenance is kept within limits.”
This is an unfair question because there are a lot of variables involved. What would be a standard ROI for an SRU unit? With the price of salt these days I can imagine the ROI has improved a lot!
“It is true that many variables play a role here, but above all it the amount of salt which the end user is replacing every year. So it is a very simple calculation for any heat treater to determine their individual ROI. 99% of the salt which ends up in the wash system is recovered and this is salt which does not need to be replaced. The only thing that contrasts with this is the cost of electricity used by the SRU and it is relatively modest. So if the system makes sense in Germany which has some of the highest electricity costs in the world it is fantastic for the American market.”
Jörn I very much appreciate the time today and look forward to seeing you at the HK22 Heat Treatment exhibition in Cologne, Germany in October of this year. Jordan Montgomery

From our friends at furnace builder SECO/WARWICK we have this press release about an order the firm received from a European knife manufacturer for a 10 bar quenching vacuum furnace.
“A renowned Czech manufacturer of machining tools, industrial knives, mulching knives, and chippers has placed an order with SECO/WARWICK for a Vector® vacuum furnace with 10 bar high-pressure gas quenching. This is one of the Group’s flagship products, and it will be used for tool steel hardening and tempering processes. The design has been customized to enable the processing of long and straight items.
“The furnace on order, based on a proven and reliable design — Vector — has been adapted to match the customer’s specific needs. SECO/WARWICK engineers have designed a unique working space with the dimensions of 600x600x1800 mm. The device modification was implemented to fit the characteristic shape of the workpieces. Apart from the non-standard dimensions of the chamber, the unit was fitted with a directional cooling option to effectively cool down long and thin knives that, due to their shape, are prone to distortion during the hardening process. With directional cooling, the goal is to reduce this undesirable phenomenon.
The furnace was customized to synchronize its operation to the dedicated thermal process for knives and chippers. The application for the device required an inverter that enables complete control over temperature at every stage of the hardening process to reduce distortion. Together with the additional option of directional cooling and the convection system, the system design helps to reduce the undesirable distortion significantly.
“The common goal was to reach an optimum matching of the furnace performance with the items processed by the customer. At SECO/WARWICK, we always build relationships and dialogue, making it possible to adjust our equipment to the customer’s particular needs. Employing outstanding and experienced engineers and having vast production expertise and a long-standing experience with furnaces intended for metal heat treatment, no solution would be impossible for us. Thus, we are renowned for customized designs of furnaces, perfectly matching the needs of our customers through technology originating from standard solutions,” — commented Maciej Korecki, VP, Vacuum Business Segment, SECO/WARWICK Group.”

On March 9, 2022 “The Monty Heat Treat News” had a mention about the astonishing rise in the price of spot nickel which we predicted would lead to a massive jump in the price of new alloy components and fixtures for the heat treatment industry. Two days later we were reporting that alloy items such as fixtures, radiant tubes and cast belts had indeed jumped by 30%-where do we stand today?
Our best indication is shown in the graph below which indicates the price of spot nickel over the course of the past year. What you can see is a slow but steady increase in the price for a year, followed by an enormous spike just weeks ago followed by a dramatic plunge leaving the price roughly twice where it was just a couple of months ago.
And where do we go from here? Well it is anybody’s guess but it would appear to be a given that for a number of reasons nickel demand will be increasing for the next number of years which will put upward pressure on pricing but by how much pressure is the question-your guess is as good as ours.
“MARCH 14, 2022; Alloy Furnace Components Jump 30% in Cost Almost Overnight; March 9, 2022 “The Monty Heat Treat News” had an item about the astounding jump for spot nickel pricing which we predicted would result in substantial price increases for all alloy items required by the heat treat industry-base trays, fixtures, belts fans and radiant tubes to name a few https://themonty.com/nickel-price-skyrockets-alloy-components-set-for-major-price-increases/
Sure enough literally within 2 days of the increase in spot nickel pricing furnace builders and heat treaters were telling us about substantial price increases from their alloy suppliers-typically in the range of 30%.
Obviously if you need alloy you need alloy and there are extremely limited options as far as alternatives go so the question becomes; buy now or wait and see what happens in the future?”

In 2020 heat treating giant Bodycote announced the opening of a brand new commercial heat treating facility in Elgin, Illinois-a facility which was built to replace the older Melrose Park, IL operation. Due to COVID restrictions the grand opening was delayed until now with an open house being held Thursday April 7 from 11:30 AM to 4:30 PM at 1620 Cambridge Drive, Elgin, IL 60123. These photos show some of the equipment which is now installed and running.
Speaking of “Bodycote Grand Openings” we would have to assume that sometime in the next few months Bodycote will be having an open house at another of their brand new facilities, this one the location in Syracuse, New York. “The Monty Heat Treat News” has already had the privilege of touring the Syracuse plant and we have to say it is a beauty.

In Plainwell, Michigan, USA we see that commercial heat treater Darby is expanding and adding new equipment which we at “The Monty Heat Treat News” always like seeing. This photo shows the expansion progressing.
“FEBRUARY 9 2022; Darby Metal Treating Appoints New Sales Manager. In Plainwell, Michigan, USA we find family owned commercial heat treater Darby Metal Treating, a company which has made “The Monty Heat Treat News” a couple of times over the years. They grace our pages again today because they just hired a new Sales Manager by the name of David Bates.
David is obviously an experienced fellow who spent over 10 years with commercial heat treating giant Bodycote. While at Bodycote he successfully closed the Melrose Park, IL location while retaining 60% of the customers to other company locations. He also oversaw the launch of the new Elgin facility from site selection to start of production, we would imagine he will do a very good job at Darby.
FEBRUARY 2021; We would be remis if we didn’t mention our most recent news item about Darby, this is from February of 2021 when the firm installed a new gas nitrider; “Rubig, a furnace manufacturer based in Wels, Austria is in the process of installing a “duo” gas nitrider which can also nitride stainless steels at a company in Michigan. Darby Metal Treating in Plainwell, Michigan is a family owned business and while they offer a number of heat treat processes they really concentrate on vacuum heat treating.”
Salt Pricing-No April Fools Joke. I believe everybody in the heat treat industry has become rather numb to price increases but this one shocked even us. A very large captive heat treater in the US who has a number of austempering lines-they were recently told that come April 1 2022 salt pricing is increasing an amazing 83%! Yikes.
Colson Casters Opens in House Heat Treat Department. Out in Jonesboro Arizona, USA caster manufacturer and in house heat treater has just moved into their brand new facility and started production, production which includes a captive heat treating department; “Move-in and production has begun at the new Colson Caster factory in Jonesboro’s Craighead Technology Park, according to an update from Jonesboro Unlimited on Wednesday. Colson manufactures standard and custom steel caster and wheel products and conducts stamping, heat treatment, welding and plating to assembly, quality assurance and shipping within its facility. The 147,000- SF factory will replace Colson’s long-time site on Airport Road.”
