China Continous Post Welding Furnace

Equipment purpose and main characteristics:
It is mainly designed for heat treatment those defected welded castings, its characteristics are as following:
Compact structure, required less installing area, saves investment;
Good temperature uniformity, high qualified products rate;
Equipped with most advanced automatic control system, excluded load and unload procedures, all working process are automatically running.
Perfect self diagnose and self checking function, once any part of the furnace is failure, the failure part will be displayed on touchable screen which enable operator eliminates it immediately.
Reliable and stable running condition, operating boxes are located at loading and unloading position, when commissioning or maintaining of the furnace, operator can use the operating boxes. Emergency buttons are designed on operating boxes, once failure or mis-operation, press emergency button, the furnace will stop running.
Equipped with aural-visual alarm.
