Kejia series of vacuum furnace is widely used for heat treatment of
metal materials in high vacuum,recursive,protective atmosphere,also
can be used for heat treatment of special materials such as carbonization
fiber with excellent thermal insulation.Vacuum Reservoir with water cooling
system.The vacuum can reach 7x10^-3 Pa with diffusion pump or molecular pump.
Features of vacuum hardening furnace:
1.Double layer steel casting with air cooling fans to keep case temperature lower;
2.High purity fiber alumina board chamber for the best energy saving;
3.The temperature is controlled by precision SCR(Silicon Controlled Rectifier) with accuracy +/-1 C and 30 segments programmable control;
4.The fast rate of temperature increasing and decreasing.
5.The furnace chamber is ceramic fiber brick with excellent thermal insulation,vacuum reservoir with water cooling system;
6.The furnace is equipped with the function of power off automatically when door furnace opening,function of over temperature alarm,etc.

Advantages of vacuum hardening furnace :
1) is completely eliminated during heating of the workpiece surface oxidation, decarburization can beobtained without deterioration of the surface of the cleaning layer.
2) high pure material ,no environmental pollution .
3) modern and advanced vacuum furnace heating chamber using insulated walls and barriers made of high-quality insulation materials, electric energy can be highly concentrated in the heating chamber, the energy saving effect is remarkable.
