RP graphite electrode is mainly made of low sulfur calcined petroleum coke as raw materials and coal asphalt as binder through calcination, batching, kneading, extruding, baking, graphitization and machining. Graphite Electrode is a conductor that releases electric energy in the electric arc furnace to heat and melt the steel scrap.
