The furnace structure is composed of a box and a bracket, both made of welded steel and steel plates. For the convenience of operators in repairing or organizing the furnace, the furnace is planned as a split structure with upper and lower parts, and the upper furnace cover can be removed. The mesh belt quenching furnace adopts full fiber composite structure, with good heat preservation function. Aluminium silicate fiber felt is selected on both sides of the furnace and on the top of the furnace. The mesh belt quenching furnace can be disassembled along with the furnace cover, with good heat preservation function, saving more than 40% energy than the brick lining.

 

Heating element of mesh belt quenching furnace: The heating element is wound with resistance wire, horizontally inserted into the furnace from one side of the furnace body, and placed above and below the furnace tube. This type of heating element is reliable in use and easy to maintain, and can be replaced without stopping the furnace when needed.

 

The characteristics of the mesh belt quenching furnace are as follows:

 

A. The muffle jar data is purely imported from Sweden;

 

B. The network tape data is selected from Nippon Steel Co., Ltd. of Japan;

 

C. The furnace body is divided into upper and lower layers, and the furnace cover composite plate and hanging rib plate are all made of SUS321 stainless steel plate;

 

D. The insulation materials are selected from ceramic fiber folding blocks produced in Shandong Luyang;

 

E. The cooling heat exchanger can be disassembled and cleaned, and can be completed in half an hour.
