Large Chamber Steel annealing electric furnace argon inert gas furnace
Vacuum Steel Annaling Electric furnace
Introduction of vacum annealing furnace
Kejia series vacuum furnace is widely used for heating treatment of metal materials in low vacuum, recursive, protective atmosphere, also can be used for heating treatment of special materials, such as carbonization process of carbon products. The furnace chamber is ceramic fiber with excellent thermal insulation; Vacuum Reservoir with water cooling system.
Features of vacuum annealing 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.
