Lucifer Furnaces designed a large heat-treating box furnace for a manufacturer in the aerospace industry. The 20-inch-high x 20-inch-wide x 40-inch-long unit will be used in the production of engine parts. This three-zone furnace with tight uniformity meets the AMS 2750 specification required by Nadcap. The new furnace, which heats to 2000°F, will complement an existing one already in operation. The company chose this equipment with the goal of shortening heat-treating cycles.
With a three-zone master/slave temperature control system and over-temperature safety controls linked to a computer interface, reduced cooling time is achieved through a fresh-air damper system. Fifty-four kW of power is generated through heavy-gauge wire heating elements in removable radiant panels located in the door as well as side walls and rear wall of the furnace. The horizontal swing door is secured with two cam locks and a safety micro switch to automatically shut power when the door is opened.
