Grate 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. Grate electrode is typically used in EAF (for smelting steel), submerged arc furnace (for producing ferroalloy, pure silicon, sr, matte, calcium carbide, etc. And electric resistance furnace, such as gratization furnace producing grate electrodes, glass-melting furnace, electric furnaces producing carborundum, etc.
