An electric furnace heating plate is an electrical heating device that converts electrical energy into thermal energy to heat materials. The heating plate of an electric furnace is usually composed of resistance wires, insulation materials, thermal conductive materials, etc. Its structure can be divided into two types: disc type and tube type.

In addition, the electric furnace may also include other components such as cooling fans, thermocouples, etc. The cooling fan is used to draw cold air into the interior of the electric furnace, expel heat, and maintain stable temperature of the electric furnace. A thermocouple is a temperature sensor used to measure the temperature inside an electric furnace and transmit the temperature signal to a temperature controller.
