Lucifer Furnaces, Inc.
The protective atmosphere elevator quench furnaces combine a pre-heat section, hardening chamber, cooling vestibule, and quench tank in one integrated unit. The furnaces, which are designed to withstand 2100¯F (1149¯C), are available in eight standard sizes, ranging in workload capacity from 15 to 55 pounds. A continuously controlled at-mosphere-from hardening chamber through vestibule to quench tank-maintains workload protection throughout the heat treating operation. An inner, vertical lift door separates the work chamber from the vestibule, and an alloy retort, gasketed to the inner door assembly, segregates atmosphere and workload from the refractory and heating elements.
