Lucifer Furnaces sold a dual-chamber furnace to LMC Industries, a full-service metal stamping and molding company base in Arnold, Mo.  The furnace will be used for processing tool steels in LMC’s tooling facility, which supports both its stamping and molding divisions. The Model HL82-H24 was chosen because it provides the versatility of heat treating a wide variety of tool steels, including powder metals such as CPM.  Built with 5 inches of multilayered firebrick and mineral-wool block insulation, the 9-inch x 12-inch x 24-inch upper chamber heats to 2300°F.                

Easy-to-replace heating elements are mounted on the side walls and door in removable panels with V grooves open to coils, providing maximum radiation and faster heat response. A lower tempering chamber with the same dimensions, built with 4.5 inches of insulating firebrick and mineral-wool block, heats to 1200°F. Both chambers are controlled by Honeywell UDC 2500 microprocessor-based digital time-proportioning temperature controllers with a separate high-limit controller on the upper chamber.
