Application of heating treatment hardening vacuum furnace

Protech series Vacuum annealing 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 7×10^-3 Pa with diffusion pump or molecular pump.

Main feature of heating treatment hardening vacuum furnace

1.Double layer steel casting 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.
