The components of an electric furnace include the furnace shell, furnace, electrical control components, and connecting components. The furnace shell is the outer shell of an electric furnace, usually made of metal material, which has the function of protecting and supporting the furnace. The furnace is the core component of an electric furnace, made of refractory materials, used to place workpieces for heating. The electrical control components include a power supply, heating elements, temperature controllers, etc., used to control the heating temperature and time of the electric furnace. The connecting components include power lines, seals between the furnace shell and the furnace, etc., which are used to connect the electric furnace with the power supply and ensure the sealing of the furnace.

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.
