Graphite electrode is a major conduction material used in the electric smelting industry, which has the properties of superior electric conductivity, thermal conductivity, high mechanical strength, oxidation and corrosion resistance in high temperature. Graphite electrode is typically used in EAF (for smelting steel), submerged-arc furnace (for producing ferroalloy, pure silicon, phosphor, matte, calcium carbide, etc.) and electric resistance furnace, (such as graphitization furnace producing graphite electrodes, glass-melting furnace, electric furnaces producing carborundum, etc.)

Graphite electrodes are classified into RP, HD,HP and UHP.
