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.

When using coil heating elements, it is necessary to pay attention to safety issues, such as preventing the coil from overheating, preventing electric shock, etc. Meanwhile, for different application scenarios, it is necessary to choose appropriate heating elements and control methods to achieve the best heating and energy-saving effects.
