Controllable atmosphere carburizing

The high strength, hardness and wear resistance of low carbon steel and low carbon alloy steel can be obtained through cementation and corresponding heat treatment process. And controlled atmosphere carburizing can effectively control the depth of carburizing layer, carbon content, hardness, and microstructure, to avoid oxidation and decarburization, greatly improve the quality of heat treatment, reduce the waste of materials, improve the production efficiency, reduce cost, stable product performance and prolong service life.

Therefore, the controllable atmosphere carburizing has been widely used in well – type carburizing furnace, sealed box-type multi-purpose furnace, continuous furnace, net belt furnace and rotary bottom furnace, etc., for the carburizing treatment of different mechanical parts.

Atmosphere control mode is dew point method and the precision of measurement value of infrared method, especially the measurements and changes in furnace gas at the same time, sluggish, basic elimination dew-point meter, infrared detector is used only for auxiliary control, is currently widely used high precision measurement, measurement and furnace gas oxygen probe control changes without delay.
