1.Graphite Electrode is made of high quality calcined petroleum coke, imported needle coke, and modified coal asphalt, the trade are RP,HD(impregnation) HP and UHP graphite electrode, the specification is dia 150-600mm.
2.Graphite Electrode produced by our company has the advantage of low resistivity, high electrical conductivity and thermal conductivity, good oxidation resistance, good thermal shock resistance, high mechanical strength, each to machine etc.
3.Graphite Electride is widely used to smelt the steel, alloy steel and other metal or nonmetal material in electric arc furnace.
