Lucifer Furnaces recently announced that LMC Industries, a metal stamping and molding company in Arnold, Mo., has added a Lucifer dual-chamber furnace to its cadre of equipment. The model HL82-H24 will reportedly be used for processing tool steels in LMC’s facility.  According to Max Vogl, Tool Room manager, LMC wanted a furnace for its tooling facility that supports both their stamping and molding divisions “to retain the cost of sending out our heat treat” and “to improve the turnaround time of heat treating in emergency and weekend situations.” 

Vogl said the model HL82-H24 was chosen “because it gives us the versatility of heat treating a wide variety of tool steels, which includes powder metals such as CPM. After searching the web and discussion with companies we researched, Lucifer seemed to be the best fit for our company and came highly recommended from a tool shop and local steel supplier we do business with.” 

Built with 5 in. of multilayered firebrick and mineral wool block insulation for energy efficiency and low outside shell temperature, the 9 x 12 x 24 in. upper chamber heats to 2300°F.  Easy-to-replace heating elements are mounted on side walls and door in removable panels with V grooves open to coils to provide maximum radiation and faster heat response.  The vertical lift counterweighted door is hand crank operated. A lower tempering chamber of the same dimensions, built with 4.5 in. of insulating firebrick and mineral wool block, heats to 1200°F. 

A 16-gauge stainless steel liner forms the work chamber, on board with a 1/6 hp motor recirculating alloy fan to direct the heated air in a horizontal flow pattern while keeping heating elements isolated from the workload.
