Lucifer Furnaces recently announced it has delivered a model HS84GT-R24 dual-chamber heat treating furnace for use with inert atmosphere to Standard Alloys, Port Arthur, Texas. The unit will reportedly be used daily in the foundry and machine shop department, which repairs pumps, compressors, and other equipment for the refining and chemical industries. Materials to be heat treated include (but are not limited to) stainless steels and high nickel alloy castings. The HSGT upper hardening chamber is designed for a positive flow of inert atmosphere, with continuous welds and gasketed door, roof plate and element terminals.
Seven inches of dry-fit multilayered lightweight insulating firebrick and mineral wool block insulation reportedly provide energy-efficient operation and low outside shell temperature. Silicon carbide elements mounted across the roof and below the silicon carbide hearth plate produce heat to 2450°F.
An SCR power supply automatically adjusts voltage to the heating elements as resistance increases, reportedly providing a steady, low amperage and voltage supply for longer element life. An SCR power supply can eliminate the manual adjustment of tap switches and power transformer.
