High Power Graphite Electrode

High Power Graphite Electrode
Raw materials are mixed and then molded. Heat treatment is then applied in the baking and graphitization process to form the finished product.


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 theproduction 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.
