Atmosphere Furnace


Atmosphere Furnaces are HTF speciality with industrial heat treating equipment. Atmospheres are used in heat treating processes to protect the surfaces of work pieces from undesired reactions such as oxidation or decarburization,to promote surface reactions to achieve a desired effect, as in case hardening processes including Carburizing, Ferritic Nitrocarburizing (FNC) or Gas Soft Nitriding (GSN), and Nitriding, or to produce no surface effect as with neutral hardening.

The atmospheres used can be nitrogen, argon, exothermic gas, endothermic gas, nitrogen-methanol, ammonia, dissociated ammonia, steam, or controlled mixtures of more than one gas.

One common atmosphere furnace arrangement is the Bell type, where the heating system is contained in a lifting box- or cylinder-shaped shell which is then sealed to a base holding the work load and containing the atmosphere seal. (Photo on right)

Another atmosphere furnace configuration is the Pit type, where the shell remains stationary and the furnace cover is removed for loading and unloading of the furnace. In either case the mating surfaces of the shell and base or cover must create a leak-tight seal. (Photo below)
