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.
