Lucifer Furnaces shipped a seventh dual-chamber furnace to a U.S. auto manufacturer. Each chamber measures 24 inches high x 24 inches wide x 36 inches long. The upper hardening chamber heats with 45 kW of power to banks of elements on the sides, door and back. The heating elements are designed with heavy-gauge wire mounted in removable holders. The upper chamber’s cast hearth plates support the workload and can be easily replaced without disturbing the heating elements. The lower tempering oven has 20 kW of power and includes a stainless steel liner that shields heating elements from the workload.
SECO/VACUUM, a SECO/WARWICK Group company, received an order from an international electric-vehicle (EV) automaker for high-pressure gas-quenching (HPGQ) and nitriding furnaces for the heat treatment of large high-pressure casting dies used in the production of aluminum underbody components. SECO/VACUUM will supply two furnaces with work zones that can accommodate loads with dimensions up to 40 x 40 x 96 inches (1,000 x 1,000 x 2,400 mm) and weighing up to 7.5 metric tons.
SECO/WARWICK will supply an electric mesh-belt furnace to bolt manufacturer Solvera Gawel Technology S.A. The line is designed mainly for carbonitriding and hardening processes and for washing and tempering of high-quality screws and other hardware manufactured near Rzeszów, Poland. The process line, which will be delivered in 2022, will be adapted for operating with endothermic atmosphere supplied from an external endothermic generator. It will consist of a loading module equipped with a weighing system, a main furnace, oil bath (for hardening the workpieces), and vibration and reloading tables. After the hardening process, the workpieces are transferred to a drum washer where they are washed, rinsed and dried.
Lucifer Furnaces delivered a high-temperature hardening box furnace to a metal stamping manufacturer based in the southeast United States. The end user is upgrading older heat-treating equipment and will employ the furnace for everyday use. Designed with thick walls of insulation for uniform heating and low outside shell temperature, the bench model has a 9-inch x 12-inch x 24-inch chamber and heats to 2300°F (1260°C). The furnace temperature is controlled with a Honeywell digital time-proportioning controller.
Can-Eng Furnaces International Ltd. has been awarded two contracts from a producer of high-volume specialty automotive fasteners. Can-Eng will supply two mesh-belt heat-treatment systems, which will include: computerized vibratory loading system, rotary phosphate removal washer, mesh-belt hardening furnace, oil-quench system, post-quench wash system, mesh-belt temper furnace and part containerization system. The fully integrated systems feature Can-Eng’s PET (process enhancement technology) system, which provides the client with complete product traceability through the thermal process, process data collection, historical event archiving, process variable trend monitoring and scheduling optimization.
Dongkuk Industries Co. Ltd., the largest manufacturer of cold-rolled medium-carbon and high-carbon steel strip in South Korea, placed an order with Ebner for a hardening and tempering line. According to Dongkuk Industries, it will be the first facility of its kind in East Asia. Ebner’s scope of supply includes an austenitizing furnace, a HICON/H2Q hydrogen quenching system, a FlexFlat martensite cooler with SmartFlat automatic flatness supervision system, a leveling furnace and an atmosphere jet cooler. A combined bainite/pearlite transformation zone will also be supplied. Medium- and high-carbon steel strip will be hardened and tempered in the facility starting in the summer of 2021.
TAV Vacuum Furnaces supplied a vacuum furnace with rapid cooling in inert gas at high pressure to a company in the aviation industry. The furnace, which has useful dimensions of 400 mm (15.7 inches) wide x 400 mm (15.7 inches) high x 600 mm (23.6 inches) long and a maximum operating temperature of 2282°F (1250°C), is suited for hardening and annealing. An inert-gas circulation system combines high flow, high pressure and multidirectional flow distribution to ensure rapid and uniform cooling of the charge. The AMS 2750E-compliant furnace includes a SCADA supervisory system.
L&L Special Furnace Co. Inc. shipped a dual-chamber heat-treating furnace to a southeastern U.S. manufacturer of various items used in the production of heavy equipment and transportation devices. The box furnace will be used to heat treat the tooling used to manufacture these items. Its top chamber, which has an effective work zone of 16 inches wide x 16 inches high x 32 inches deep, is used to harden tool steels. Its bottom chamber, which has an effective work zone of 14 inches wide x 14 inches high x 32 inches deep, is used for tempering, stress relief and preheating.
