The silicon carbide heating element is a kind of non-metal high temperature electric heating element. It is made of selected super quality green silicon carbide as main material, which is characterized by high-applied temperature, anti-oxidization, anti-corrosion, long service life, little deformation, easy installation and maintenance. It is widely used in various high temperature electric furnaces and otherelectric heating devices,such as in the industries of magnet, eramics,powder metallurgy, glass, metallurgy and machinery etc. We adopt new production process of cold ends,so our SIC heating elements have excellent specific rate of heat zone resistance and cold end resistance,to avoid over-temperature of cold ends to damage the furnace body.
