Graphite electrode are manufactured with high quality raw materials including petroleum cokes, needle cokes and coal tar pitch through the production processes of calcining, crushing, screening, dosing, kneading, extruding, baking, impregnation, graphitization, machining. Our products products are characterized by superior compact structure, good electrical and thermal conductivity, high mechanical strength and high resistance to oxidation and corrosion in high tempertature. The graphite electrode are widely used in electric arc furnace and ladle refining furnaces foe steel making and used in ore smelting furnace for producing industrial silicocn, yellow phosphorus, corundum, nonmetals and so on, it is one essential part of the raw material industry.
