An investment castings manufacturer's heat treat department received a large floor-standing box furnace from a North American specialty furnace company. The furnace will be used as support in the client's tool and die production along with tempering of finished castings.
The L&L model XLE3436 box furnace from L&L Special Furnace has an effective work zone of 34” wide by 22” high by 32” deep. It is equipped with a direct-lift vertical door with a floor switch to activate. The cantilevered vertical door eliminates the need for the upright structure to reduce the overall height of the equipment.
Tom Schulz, sales manager at L&L, highlights the key role this will play for the heat treat department, saying that this type of furnace is the company's “workhorse when it comes to thermal processing.”
The inert blanketing gas enables the part to be heat-treated with minimal surface de-carb. A stack light indicates the furnace status via an audible and visual indicator light mounted on top of the control.
Additionally, the furnace is equipped with a pyrometry package that has reference control thermocouple ports along with corner locations to record the high and low points within the unit as indicated by the latest temperature uniformity survey.

Skuld LLC announced that they had purchased the site belonging to the former Champion Foundry in Piqua, Ohio, a gray and iron foundry that had closed in March 2017. The company will continue to be focused on innovation in the metals industry, serving their clients through a number of innovations related to novel materials and manufacturing technologies.
The four buildings with nearly 32,000 square feet of space are being refurbished to be capable of casting a wide range of ferrous metals (gray, ductile iron, steels) and nonferrous metals (aluminum, brass, bronze, copper, nickel alloys). The plant will initially have 3,000 tons of capacity but plans are in place to expand to ten times that capacity in the next few years.
Skuld will be installing machining, foam blowing, a printer farm, and heat treating, adding to their current 5 small heat treat furnaces and adding to their operations, which primarily consist of lost foam casting. The new installations will aid the company as they serve the defense, tooling, and heavy equipment industries. They are also beginning to target production of heat treat fixtures and baskets.
Sarah Jordan, CEO, Skuld LLC
Production at the new site is scheduled to begin in April 2024. Sarah Jordan, CEO of Skuld LLC, commented, "Skuld is looking forward to getting our induction melting furnaces installed so that we can produce higher temperature iron, steel, and nickel alloy castings." She continued, "many [heat treaters] have custom furnace components and fixtures that require high temperature metals. These parts can have extremely long lead times, sometimes over a year, which is a problem if they are stocked out." By using their new tooling free processes, Jordan says that they can help clients drive lead times down to less than a month, if not a day for emergency spares.
Skuld is a company founded by two metallurgical engineers, Mark DeBruin and Sarah Jordan, with ties to the heat treat industry. DeBruin is the former CTO of Thermal Process Holdings. Jordan formerly worked in heat treating at Timken and Commercial Metals and was a staff engineer for Nadcap heat treat.

Bringing forward plans by two years, Wallwork Group have signed for a second hot isostatic press. Following hot on the heels of opening their £10 million Wallwork HIP Centre, Wallwork Group is installing this HIP to meet and serve increasing demand from various manufacturers.
David Loughlin Business Manager Wallwork HIP Centre
This second HIP from Quintus Technologies, a high pressure manufacturer with North American locations, has been contracted following Quintus completing the commissioning of the first HIP in the third quarter of 2023.
“We expected strong demand from UK castings, 3D printing, powder fabrication, and near-net-shape manufacturers. Especially, as the UK is currently under-served with hot isostatic pressing capacity,” says Wallwork HIP Centre, business manager, David Loughlin.
Adds Simeon Collins, group director of Wallwork, “Demand from customers for processing components in our first hot isostatic press has been astonishing. It is prudent to bring forward planned investment for the next HIP, knowing it will take most of 2024 to build and install. We hope to have it up and running by early 2025. Deciding to prepare pits for expansion during the first installation has proved right.”
The second HIP will be identical to the first, operating at pressures from 40 to 207 MPa (5,800 to 30,000 psi) and temperatures up to 2282°F (1250°C). It will also have the latest rapid cooling technology, as well as the capability to offer increased cycle pressures at elevated temperatures, complements engineering advances in metal 3D printing and more.

A Louisiana-based foundry — a supplier of iron, stainless, and specialty alloy castings for paper/pulp, energy, mining, and petrochemical customers — is getting financial support for infrastructure investments from the state as part of a three-phase effort to expand its 3D printing operation for sand molds.
JB Shoaf President Howell Foundry
Howell Foundry plans to expand its 3D-printing capabilities following a $7.4 million update to its operation in St. Francisville, LA. This expansion is expected to create 26 new jobs and retain 22 current, according to an announcement by the Louisiana Economic Development agency. Work was scheduled to start in December for completion by the end of 2027, LED said.
The state will provide a $400,000 performance-based forgivable loan for infrastructure work, contingent upon Howell Foundry meeting investment and payroll targets. Also, the foundry is expected to participate in the state’s Quality Jobs and Industrial Tax Exemption programs.
The foundry emphasizes its ability to deliver complex parts with quick turnaround, using 3D-scanning to convert parts or patterns into reproducible programs, casting process simulation to plan and set-up production, and 3D-sand printing of molds and cores.
“Howell Foundry combines modern-day 3D innovations with proven craftsmanship in one of the oldest known trades to produce rapid and reliable solutions to its valued customers who are primarily located on the Gulf Coast,” stated company president JB Shoaf said. “We take great pride in being a local business that serves local businesses.”
What is deoxidation and how can it be useful for energy savings? In fact, can the process really save money and improve the quality of iron?
Sometimes our editors find items that are not exactly “heat treat” but do deal with interesting developments in one of our key markets: aerospace, automotive, medical, energy, or general manufacturing. To celebrate getting to the “fringe” of the weekend, Heat Treat Today presents today’s Heat Treat Fringe Friday article that answers these questions. Hint: Deoxidation is helpful, and the article points to how annealing heat treatment may not be necessary in order to meet the ferritic ductile iron elongation specification levels.
An excerpt:
Ductile iron producers typically add copper to the melt to enhance the material’s tensile strength. That becomes unnecessary when base iron is deoxidized prior to magnesium conversion treatment. The deoxidized iron’s strength rises to near 100,000 psi after deoxidation, without copper addition. Deoxidation removes the suspended MgO oxide particles that reduce strength and elongation in ductile iron.

To celebrate getting to the “fringe” of the weekend, Heat Treat Today presents today’s Heat Treat Fringe Friday: the recent acquisition of U.S. Steel by Japan’s Nippon Steel Corporation and some coverage on what may derail the sale.
Nippon Steel Corporation (NSC), Japan’s largest steelmaker and one of the world’s leading steel manufacturers, and United States Steel Corporation (U. S. Steel), a leading steel producer with competitive advantages in low-cost iron ore, mini mill steelmaking, and best-in-class finishing capabilities, announced that they have entered into a definitive agreement pursuant to which NSC will acquire U. S. Steel for a total enterprise value of $14.9 billion. The transaction has been unanimously approved by the Board of Directors of both NSC and U. S. Steel.
NSC’s acquisition of U. S. Steel will enhance its world-leading manufacturing and technology capabilities and enable it to expand the geographic areas in which NSC can better serve all of its stakeholders. The transaction will further diversify NSC’s global footprint by significantly expanding its current production in the United States, adding to its primary geographies of Japan, ASEAN, and India. As a result of NSC’s acquisition of U. S. Steel, its expected total annual crude steel capacity will reach 86 million tonnes – accelerating progress towards NSC’s strategic goal of 100 million tonnes of global crude steel capacity annually.
NSC President Eiji Hashimoto said, “We are excited that this transaction brings together two companies with world-leading technologies and manufacturing capabilities, demonstrating our mission to serve customers worldwide, as well as our commitment to building a more environmentally friendly society through the decarbonization of steel.”
President and Chief Executive Officer of U. S. Steel, David B. Burritt, said, “For our U. S. Steel employees, who I continue to be thankful for, the transaction combines like-minded steel companies with an unwavering focus on safety, shared goals, values, and strategies underpinned by rich histories. For customers, U. S. Steel and NSC create a truly global steel company with combined capabilities and innovation capable of meeting our customers’ evolving needs. [December 18’s] announcement also benefits the United States – ensuring a competitive, domestic steel industry, while strengthening our presence globally. Our shared decarbonization focus is expected to enhance and accelerate our ability to provide customers with innovative steel solutions to meet sustainability goals.”
But this pushback is not at all unexpected from a Japanese perspective. In the perspective of Kyodo News, the regulatory authorities in America and “strict antitrust laws” could continue to prove to be an impediment to the full acquisition.
Sławomir Tomaszewski Vacuum Melting Team Director SECO/WARWICK Source: LinkedIn
One of the world’s largest producers of jet engines has modernized their casting furnace, which was last updated two decades ago.
This company has two casting units supplied two decades ago by RETECH, a North America-based company belonging to the SECO/WARWICK Group. The modernization project was for the VIM EQ furnace - a system for the production of castings in equiaxed crystallization. It will involve replacing almost all the furnace components except the power supply, melting chambers and mold. The platforms will also remain unchanged. The remaining components will be replaced with more modern, ergonomic, and user-friendly parts and assemblies.
Says Sławomir Tomaszewski, vacuum melting team director at SECO/WARWICK, “This order includes the complete elimination of hydraulic components by replacing them with electrical components such as an elevator drive or crucible rotation drive. In addition, two old feeders: one for loading crucibles, the other for removing disposable crucibles, will be replaced with a modern system that can perform both activities."
He added, "An additional advantage of the operation will be the fact that the furnace operator will not have to come into physical contact with hot used crucibles, because they will be removed automatically without human intervention."
