If combustion and its related efficiencies were not challenging for us, we and others would not dedicate so many new resources to the topic. This article will point out some of these available resources, including the pages of Industrial Heating.
Can-Eng Furnaces International Ltd. was contracted to engineer and commission two large-capacity heat-treatment furnaces for a global producer of highly engineered metal earth-moving, construction and mining equipment. As part of this turnkey contract, Can-Eng designed and commissioned individual tempering and stress-relieving furnaces. Both systems were assembled and tested at Can-Eng’s Niagara Falls facility prior to shipment and commissioning. They are part of a major expansion by the company to satisfy increased demand for large steel castings and weldments used as part of their equipment designs.
Nonconventional machining consists of material removal by thermal or chemical methods. The most common processes that use rapid melting of material are electrical-discharge machining (EDM) and laser-beam machining (LBM).
Nucor Corp. awarded SMS group a follow-up order for the supply of reheat and heat-treatment facilities for its plate mill being built in Brandenburg, Ky. Nucor previously ordered a slab-casting machine for the new mill from SMS group in 2019. The follow-up contract is for all of the plate mill’s slab and ingot reheat equipment, a heat-treatment line for heavy plate up to 14 inches (356 mm) thick and a continuous heat-treatment line for plate between 0.19 and 14 inches (4.8 and 102 mm) thick and up to 168 inches (4,267 mm) wide.
This article is a Q & A with Rune Strand regarding ExpaniteHard-Ti. Strand is project manager and material scientist at Expanite A/S, and he holds an MSc in material science and manufacturing. He has spent most of his career in the field of surface hardening and heat treatment of stainless steel.
Andritz received an order from Slovenia’s SIJ Metal Ravne for the supply of a complete heat-treatment plant, including two double-chamber furnaces, a charging machine, high-volume quenching tanks and an automation system. Commissioning is scheduled for the second quarter of 2021. Each double-chamber furnace consists of a high-temperature furnace (1202-2228°F) with recuperative burners and a low-temperature furnace (392-1526°F) with forced circulation. Both furnace types meet the qualifications for AMS 2750E. The charging machine is designed as a portal-type unit for handling charging material up to 25 tons.
