An electric sintering furnace is a device that uses electrical energy to heat materials and cause physical or chemical changes at high temperatures, thereby achieving the purpose of sintering. Electric sintering furnace is an important material processing equipment with a wide range of application fields and significant economic value. During use, it is necessary to pay attention to safe operation and regular maintenance to ensure its normal operation and extend its service life.

The working principle of a sintering furnace mainly revolves around sintering materials in high-temperature environments. It is usually equipped with powerful heating elements such as electric heating wires, silicon carbide rods, or electromagnetic induction heating devices, which can quickly raise the temperature inside the furnace to the desired sintering temperature. During the sintering process, a series of physical and chemical changes occur in the particles inside the material. The atoms on the surface of the particles begin to diffuse, and adjacent particles gradually form necks and bond together. At the same time, the pores inside the material gradually shrink, the density increases, and the crystal structure may also change, thereby significantly improving the performance of the material.
