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.

A coil heating element is a heating element that uses current to generate resistance and heat through a coil, converting electrical energy into thermal energy. It is usually made of high resistance materials, such as nickel chromium alloy or iron chromium aluminum alloy. The shape of the coil can be linear, circular, or spiral, and the appropriate shape can be selected according to different application requirements.
