Refractory brick type electric resistance trolley type heat treatment furnace for pipes

1. Furnace application

The electric resistance trolley type furnace is mainly used for boronizing the steel pipes.

The bogie hearth furnace is mainly comprised of furnace shell, lining, furnace door, furnace door lifting mechanism and door compression mechanism, bogie, bogie traction mechanism, sealing between furnace body and bogie, heating element and fixed device, and temperature control system.
