Graphite Electrodes

Graphite electrode is mainly made of petroleum coke and needle coke as raw materials, and coal asphalt as binder. It is made by calcination, batching, mixing, pressing, roasting, graphitization and machining. It is a conductor for heating and melting the charge in the form of electric arc in the electric arc furnace. It can be divided into ordinary power graphite electrode, high power graphite electrode and ultra-high power graphite electrode. (1) For arc steelmaking furnace Electric furnace steelmaking is a major user of graphite electrodes. The output of eAF steel in China accounts for about 18% of the output of crude steel, and the graphite electrode used in steelmaking accounts for 70% ~ 80% of the total amount of graphite electrode. Electric furnace steelmaking is the use of graphite electrode into the furnace current, the use of electric extremes and charge between the arc generated by the high temperature heat source to smelting.
