Atmosphere Furnace is used in many industrial and laboratory research applications, where heat treatment is done under inert atmosphere. This inert atmosphere furnace is supplied with vacuum pump, gas flow meter and needle valves for vacuum and gas purge. Usually, Argon (Ar) and Nitrogen (N2) gases are used to create inert atmosphere. For specific applications; where, hydrogen gas is used, we also make such atmosphere furnace with explosion proof safety provisions.
In atmosphere furnace, little vacuum (up to 0.1MPa) is created using a rotary vane oil filled vacuum pump then inert gas (Argon or Nitrogen gas) is purged. In this process, material (typically metals and ceramics) is surrounded by argon or nitrogen gas which prevents oxide formation. These inert atmosphere furnaces are used to carry out processes such as annealing, brazing, and heat treatment of materials that are prone to oxidation.
STERICOX is a leading atmosphere furnace manufacturer in India and makes these furnaces in different working temperature ranges (1100°C, 1300°C and 1600°C) and heating zone sizes. Each inert gas furnace is supplied with a rotary vane vacuum pump and unit is fitted with gas inlet and outlet valves, gas flow meter and dial type pressure gauge.
