Wisconsin Oven designed and built a horizontal spray-quench furnace for C/A Design, a supplier to the defense industry based in Dover, N.H. The furnace will be used for the solution treatment of aluminum. It is designed to soak the product load at temperature in the furnace before a pusher mechanism rapidly moves the load into the spray quench, which offers reduced distortion in comparison to submersion quenching. The maximum temperature for this system is 1150°F (621°C), and it has sufficient capacity to heat a 200-pound aluminum load plus the work grid and product fixture.
Sheffield Forgemasters placed an order with Andritz for the supply of seven industrial furnaces for the company’s proposed 13,000-metric-ton forging line. Austria-based Andritz will design, build and deliver four heat-treatment furnaces and three forging furnaces. The furnaces, with up to 1,000 metric tons of capacity, will feature rail-mounted car bottoms that can roll in and out for the loading of ultra-large components. They will also include dual-fuel burners that can switch to hydrogen if the technology to move away from natural gas becomes viable. The largest furnace will measure 60.5 feet long x 31 feet wide x 26.5 feet tall.
Andritz received an order from Shandong Nanshan Aluminum Co. for the supply of two continuous heat-treatment lines and one continuous process-treatment line to produce aluminum and aluminum alloy sheets for the automotive and aerospace industries at its mill in Longkou, Shandong. Andritz’s scope of supply includes engineering, equipment, supervision of erection and commissioning of the complete lines (including electrical and automation equipment). Start-up will take place in 2025.
Industrial process heating systems supply necessary heat to produce goods used by consumers and industries. The heat is supplied mainly from fuels, steam and electricity used in various types of heating equipment, such as furnaces, ovens, heaters and kilns.
Assan Alüminyum, a flat-rolled aluminum manufacturer based in Turkey, ordered four aluminum coil-annealing furnaces equipped with the Vortex 2.0 system from SECO/WARWICK. The furnaces are equipped with an improved nozzle system that produces increased heat-transfer efficiency. According to SECO/WARWICK, Vortex guarantees a lack of local overheating on the coil surface, which significantly affects the final quality of the heat-treated material, and provides a significant reduction in the total process time compared to traditional systems. The system operates with a temperature uniformity +/-3°C.
The faster the refractory installation, maintenance or repair, the more efficient and, by extension, profitable the company as savings fall to the bottom line.
Between May and December 2023, Nutec Bickley will manufacture and install five completely new furnaces for a U.S. manufacturer of high-quality alloy-steel and carbon-steel closed-die forgings. On-site work will be completed by Nutec Bickley one furnace at a time so that no more than one furnace will be out of operation in any given month to help the forging company keep its production schedules on track. The contract involves five lift-up furnaces: two for tempering and three for austenitizing. Each furnace will be fitted with a comprehensively modernized combustion system, control systems, complete fiber flues, and an exhaust and pressure control system. Operational temperature ranges will be 900-1950°F (480-1065°C) for the austenitizing furnaces and 840-1600°F (450-1065°C) for the tempering furnaces.
Delta H manufactured and supplied twin convection furnace systems to Winston Heat Treating of Dayton, Ohio. The SCAHT-HD series furnaces replaced older tempering systems that were extremely difficult to qualify to Class 5 (+/-25°F). The furnaces had to be heavy duty for rugged daily use in a commercial heat-treating facility. Another challenging design aspect was the ability to heat rapidly but cool just as fast without damage to interior metal. A load heat treated at 1000°F (538°C) could be quickly followed by the next at 300°F (149°C). The result is that the Delta H furnaces can heat and cool in a fraction of the time of the previous systems.
Nutec Group announced effective Feb. 1, 2023, Genaro F. Cueva will step down from the position of CEO, remaining in his position as Chairman of the Board. He will be replaced as CEO by Daniel Llaguno, currently president, Nutec Fibers Division. This transition had been announced internally back in September 2022.
