Silicon carbide rods, also known as silicon carbide heating element is the use of high-quality green silicon carbide as the main raw material, the processing system also, high-temperature silicification, recrystallization of rod-shaped non-metallic high-temperature heating components. Compared with the metal heating element, silicon carbon rod has the characteristics of high temperature, anti-oxidation, corrosion resistance, long life, small deformation, easy installation and maintenance. Therefore, silicon carbon rods are widely used in magnetic materials, powder metallurgy, ceramics, glass, metallurgical and mechanical industries such as a variety of high-temperature electric furnace and other electric heating equipment. The ED type is the standard SiC heating element. A high-density self-bonded silicon carbide element, ED type is available in a large range of diameters and lengths.
