Box furnace from Lucifer Furnaces designed for precision metal stampings

Lucifer Furnaces has delivered a general-purpose box furnace to a manufacturer of precision metal stampings. The model HL7-M24 has chamber dimensions of 12 by 18 by 24 in. and heats to 2,300 degrees F. Powered at 15 kW, it supplies heat through coil-wired, heavy-duty heating elements in V-grooved radiant panels on the sides, back, and door of the furnace.

Insulation includes 5 in. of hot-faced insulating firebrick with cold-faced mineral wool block behind. The roof is lined with ceramic fiberboard to eliminate cracking potential. A 1-in.-thick cast hearth plate protects floor insulation and provides a flat work surface.
