Lucifer Furnaces, Inc. recently shipped two dual chamber atmosphere muffle ovens to a customer for the purpose of heat treating superconducting wire used in medical, pharmaceutical and industrial applications. The superconducting wire will be processed inside the muffle under a positive flow of protective nitrogen atmosphere. Each furnace has two 12” x 12” x 18” chambers capable of temperatures to 760°C with a uniformity of +/- 5°C.
Unique door mounted fans circulate the heated atmosphere inside the work chamber, providing uniform temperature throughout. A Honeywell cascade programmer coupled with an SCR power supply provides precise temperature control inside the muffle around the workload. The furnace is designed with lightweight insulating firebrick, a silicon carbide hearth plate, and heavy gauge coil wound heating elements located on both sides as well as under the muffle.
A double pivot horizontal swing door with alloy cladding and a high temperature gasket seals against the muffle to minimize heat loss while providing easy access to the work chamber and safety for the operator.
