RX3 series box-type resistance furnace, furnace shell is welded angle iron and steel plate, lining is built into the ultra-light saving refractory bricks, using a ceramic fiber insulation materials and swelling powder is a typical energy-lining between the shell and lining structure. The heating element is Raozhi high resistance alloy wire made of, mounted on the two walls and the bottom of the furnace brick shelf, the workpiece is heated in heat-resistant steel of the furnace bottom plate, the lift door by hand sprocket to carry out, in the upper part of the door there is a disconnect device, when the door opened, electric power that is cut off to ensure the safety of the operator, not one thermocouple hole on the roof, when using thermocouples inserted into the furnace, the temperature control cabinet to control the furnace temperature and over-temperature protection.
