Graphite electrode is a kind of high temperature resistant graphite conductive material made from petroleum coke and asphalt coke as aggregate and coal asphalt as binder through raw material calcination, crushing and grinding, batching, kneading, forming, roasting, impregnation, graphitization and machining. It is mainly used for steelmaking and smelting yellow phosphorus, industrial silicon and abrasive. It is a conductor that releases electric energy in an electric furnace to heat and melt the furnace charge.
The production process of graphite electrode can be divided into three kinds: pressure vibration method, NC automatic forming method and machining method. The main method used in domestic mold production is machining method.
According to national standards, graphite electrode can be divided into ordinary power graphite electrode, high power graphite electrode and ultra-high power graphite electrode. There is also a folk model in China, quasi ultra-high power graphite electrode (SHP), which is a product between high power and ultra-high power graphite electrode. This model is not available in the actual product classification. The performance is close to that of ultra-high power graphite electrode, but the price is lower than that of ultra-high power graphite electrode.
