Product Description
Graphite electrode, mainly from the domestic petroleum coke and imported needle coke, is widely used in electric arc furnace, ladle furnace, submerged arc electric furnace for the production of alloy steel, metal and nonmetallic materials. Our graphite electrodes include regular power, high power, super high power and ultra high power. They are characterized by low resistivity, good electric and thermal conductivity, high resistance to oxidation and thermal shock, high mechanical strength, ect. Our plant offers various dimensions and grades to meet customers’ requirements for the specific applications.
