Pit furnace

Pit type vacuum gas carburizing furnace is new type and energy-saving batch type furnace,working temperature is 950℃,mainly used for rod and long axis steel mechanical parts for gas carburizing,the workpiece is vertically loaded in furnace tank,not easy to deformation. 


Pit type vacuum gas carburizing furnace is mainly composed of furnace shell, furnace lining, heating device, muffle tank, loading frame, the furnace cover, and furnace cover lifting mechanism, etc. Furnace body is cylindrical deep well, workpiece is vetically loaded in furnace tank for heating,Pit type furnace is usually placed under the ground plane in the workshop, also is placed above the ground plane, or ground level fluctuation in each half. 


pit type vacuum gas carburizing furnace can also be used for machine parts for quenching, tempering, annealing, normalizing, carburizing and carbonitriding heat treatment.etc.
