Wisconsin Oven Corp. shipped a natural-gas-fired, dual-chamber furnace to the automotive industry. The furnace, which will be used for preheating dies, has a maximum operating temperature of 1250°F and work-chamber dimensions of 6 feet wide x 4 feet long x 6 feet high. It has sufficient capability to heat 4,000 pounds of steel from 70-1100°F within four hours when loaded into a preheated furnace.
Each chamber features a carbon-steel die support structural frame to accommodate two dies, one above the other. Each support structural frame is designed to support a 2,000-pound load. Guaranteed temperature uniformity of ±15° F at 800°F and 1100°F was verified through a nine-point profile test conducted in an empty furnace chamber under static operating conditions.
