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.

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.
