Graphite Electrodes 1. Graphite Electrodes, petroleum coke and needle coke as raw materials, then calcined, mixing, extrude/forming, baking, impregnate and machining. graphite electrode is a conductor that heats and melts in an electric arc furnace. According to the quality index, the graphite electrode can be divided into RP,HP,UHP grade.Advantage 1 High purity and high density, strong chemical stability 2 Surface can be treated with anti-oxidation, long service life 3 General power graphite electrode Conductive, thermal and thermal shock
