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.

This type of heating element is widely used in various fields, such as industrial production, food processing, medical equipment, etc. It has advantages such as high efficiency, safety, and environmental protection, and is considered a relatively advanced heating method.
