Lucifer Furnaces received an order from Century Die Company LLC for a single-chamber furnace. The unit has a working chamber size of 9 inches high x 12 inches long x 21 inches deep and heats to 2200°F. Energy-efficient lightweight firebrick lines the chamber with mineral-wool backup insulation, and easy-to-replace heating elements are situated along both side walls for uniform radiation. The furnace comes standard with a horizontal swing door and safety microswitch as well as a ceramic hearth plate to support the workload and protect the floor brick insulation. Century Die, a blow mold specialist based in Fremont, Ohio, is adding to its in-house heat-treat capabilities because many of its customers run a 24/7 operation and cannot allow excessive downtime.
