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.
Guaranteed temperature uniformity of ±10°F at setpoints of 870°F, 920°F and 985°F was documented with a 12-point profile test in an empty oven chamber under static operating conditions and was performed in accordance with BAC 5621F specifications. This system achieved a quench time of 7 seconds from the time the oven door starts to open until the load is fully submerged.
