silicon carbide 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 made into blank,silicided under high temperature and re-crystallized.Compared with metal electric heating element,this kinkd of element is characterized by high-applied temperature,anti-oxidezation,anti-corrosion,long service life,little deformation,easy installation and maintenance.Therefore,it is widely used in various high temperature electric furnaces and other electric heating devices, such as in the industries of magnet,ceramics,powder metallurgy,glass 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, saving energy, long life, avoiding over-temperature of cold ends to damage the furnace body.
