Commercial heat treater Specialty Steel Treating of Fraser, Mich., invested in an AFC-Holcroft UBQ (universal batch quench) furnace and a UBT (universal batch temper) annealing furnace as part of a larger multiyear equipment standardization program intended to replace older equipment provided by another supplier. The UBQ and UBT furnaces are near duplicates to equipment recently provided by AFC-Holcroft as part of the same program. Delivery of the UBT is expected in the second quarter of 2019 to the site on Malyn Road in Fraser, with the UBQ to follow in the third quarter to the Commerce Road plant in Fraser.
Wisconsin Oven Corp. shipped a horizontal solution-treat system with a chiller to a manufacturer in the aerospace industry. The electrically heated system has a maximum oven operating temperature of 1100°F and work-zone dimensions of 12 feet, 3 inches wide x 3 feet, 11 inches long x 4 feet, 6 inches high. It was designed to heat a 2,840-pound gross load consisting of a mixture of aluminum and steel to 1000°F, provide a soak at temperature and then quickly move the load into a quench tank. A hydraulically operated load/unload system lowers and raises the load for quenching.
Every manufacturing (or heat treat) plant has raw materials that come into the receiving dock and finished products that are sent out from the shipping dock. Between the receiving and shipping docks, transformation occurs. Transformation adds value to the materials in a step-by-step process, and energy is required. Evaluating the process transformation steps and energy inputs provides clues about where to look for energy savings.
Lindberg/MPH shipped a 2012°F (1100°C) crucible furnace to a research-and-development laboratory in the nuclear industry. The furnace will be used for laboratory melting applications including annealing, ashing, carbon firing, ceramic firing, hardening, nitriding, normalizing, sintering, solution treating and stress relieving. It is designed for use with a variety of crucibles, including alumina, mullite, quartz and metallic.
Surface Combustion supplied two new Allcase batch integral-quench furnaces to Cambridge Heat Treating of Cambridge, Ontario. Cambridge also purchased two used Allcase furnaces. All four units were installed in the same line along with a previously purchased 30- x 30- x 48-inch Allcase with top cool. All the furnaces are serviced by Surface’s charge car, Uni-DRAW batch tempering furnaces, washers and an RX endothermic-atmosphere gas generator. The 36- x 48- x 36-inch batch heat-treat line greatly expands Cambridge’s capacity for carbonitriding, carburizing, neutral hardening, ferritic nitrocarburizing (FNC) and normalizing.
The Industrial Heating Equipment Association (IHEA) announced that the 2019 Fall Seminars and Fall Business Conference will be held in Cleveland, Ohio, Sept. 24-26. The technical seminar series will be held on Tuesday and Wednesday, followed by the Fall Business Conference on Thursday at the Intercontinental Cleveland. The Combustion Seminar and the Safety Standards and Codes Seminar will take place concurrently over both days. There will also be two separate one-day seminars on infrared heating and induction technology. Attendees of all four seminars will enjoy access to IHEA’s tabletop exhibition and reception on the afternoon of Tuesday, Sept. 24.
SMS group received a contract from Chinese steel and forging company Daye Special Steel Co. Ltd. for the engineering and delivery of a high-speed hydraulic open-die forging press. The press operates with a forging force of up to 50 MN and an upsetting force of 60 MN. The high forging frequency of the press enables sophisticated materials requiring a narrow temperature range to be forged and reduces machining times. Daye Special Steel plans to use the press, which will be installed in its Huangshi plant, to forge a variety of products of high-temperature alloys and special steel. Commissioning is scheduled for May 2020.
