Raw Materials Needed To Produce Graphite Electrodes

The main raw materials for the production of various carbon graphite products are petroleum coke, pitch coke, metallurgical coke, anthracite, coal tar pitch, coal tar, anthracene oil, natural graphite, and other auxiliary materials such as coke powder and quartz sand. Graphite electrode is a kind of high temperature resistant graphite conductive material produced by a series of processes such as kneading, molding, roasting, impregnation, graphitization, mechanical processing, etc., using petroleum coke and needle coke as aggregates, and coal pitch as binder. . Graphite electrode is an important high-temperature conductive material for electric furnace steelmaking. Electric energy is input to the electric furnace through the graphite electrode, and the high temperature generated by the arc between the electrode end and the charge is used as the heat source to melt the charge for steelmaking. Some other submerged arc furnaces for smelting yellow phosphorus, industrial silicon, abrasives and other materials also use graphite electrodes as conductive materials. Graphite electrodes are also widely used in other industrial sectors because of their excellent and special physical and chemical properties. The raw materials for the production of graphite electrodes are petroleum coke, needle coke and coal pitch.
