Manufacturer of RP500 Graphite Electrodes for Metal Smelting Application
Manufacturer of RP500 Graphite Electrodes for Metal Smelting Application
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. Our plant offers various dimensions and grades to meet customers’ requirements for the specific applications.
The graphite electrode for arc furnaces and ladle refining furnaces for steel industries/steel plant in steel making.
