Product Features:The Graphite electrode is mainly made of petroleum coke and needle coke ,and the coal bitumen is used as a binder. It is made by calcination , compounding ,kneading ,pressing roasting ,graphitization and machining .It is released as an arc in electric arc furnace steelmaking .The electric energy acts as a conductor to heat and melt the charge. According to the quality index of graphite electrode,it can be divided into ordinary power (RP), high power (HP) and ultra high power (UHP).FAQ
