Lucifer Furnaces, Warrington, Pa., has designed a multi-unit modular pot furnace system for a major aerospace manufacturer in the U.S., who will use these furnaces to increase heat treat capacity.
Each of the four Model 2057 Pot Furnaces is connected to a single freestanding NEMA 1 control panel. Each furnace is heated electrically with 18 KW of power to heavy-duty coiled elements in removable holders on all four sidewalls. Roof and side cover bolted to the frame of each furnace can be removed for easy service access. The units are insulated with 5-in. of multilayer insulation consisting of dry-fit hot face lightweight firebrick backed by cold face mineral wool.
The vestibule at the top of each furnace reduces heat loss between the pot wall and the firing chamber. The 10-in. ID x 10-in. deep pots are constructed of RA300 alloy with 3/8” thick walls designed with a flange for sealing against the roof plate to minimize heat loss.
