Original Press Release:
Gas-tight Protective Atmosphere Furnaces
A comprehensive line of gas-tight protective atmosphere furnaces is offered by Lucifer Furnaces, Inc. as a low-cost heat treating alternative to retort-equipped furnaces.
The GT models are constructed with a continuously welded heavy gauge sheet steel shell and a gasketed door assembly to provide a positive seal. The furnaces are designed to operate in either an inert or a flammable/combustible atmosphere at temperatures up to 2100 degrees F.
In facilities where heat treating under a protective atmosphere is performed continuously, GT units are particularly cost-effective.
Because GT units provide a clean finish to most tool steels, the time and expense of machining parts is minimized.
In addition to the welded steel shell, other construction features include lightweight firebrick or ceramic fiber insulation lining the chamber; a hearth plate to protect the floor and support the workload, and coilwound heating elements on the side walls.
The only accessories required to heat treat under inert atmosphere are a flowmeter and regulator. Units may operate under flammable atmospheres with the addition of required safety equipment.
Inlet pressure of 5 PSI and a flow rate of approximately 10-15 volume changes per hour are recommended.
GT units are manufactured in 16 bench model sizes and 16 floor stand models. Chamber sizes range from 6" x 6" x 6" to 24" x 24" x 48". Dual chamber models are also available.
All furnaces are standard with digital temperature controls and are completely pre-wired, tested, pressure-checked and shipped ready for connection to customer's power and atmosphere supply.
