This kind of heat treatment assembly line adopts Japan foreign furnace technology and is manufactured and inspected according to the standard of resistance furnace industry. Main components adopt imported products and the quality of manufacturing and assembling has reached to the advanced domestic level. 

This kind of heat treatment line is a full automatic production line composed of the techniques such as material loading, pre-washing, material distributing, hardening, cooling, post-washing, tempering and cooling. 

Main furnace's heating adopts low voltage, high current transformer, which lengthens the service life of radiant tube and makes it convenient for maintenance and renewal. 

The wire mesh belt adopts synchronous rotating roller, which makes belt endure the lowest tension during operation in order the lengthen the service life.
