Raw materials required for producing graphite electrodes

The main raw materials for producing various carbon graphite products include petroleum coke, asphalt coke, metallurgical coke, anthracite, coal tar, anthracene oil, natural graphite, and other auxiliary materials include coke powder and quartz sand. Graphite electrode is a high-temperature resistant graphite conductive material produced through a series of processes, including mixing, shaping, calcination, impregnation, graphitization, and mechanical processing, using petroleum coke and needle coke as aggregates and coal tar pitch as binder. Graphite electrodes are important high-temperature conductive materials for electric furnace steelmaking. Electric energy is input into the furnace through graphite electrodes, and the high temperature generated by the arc between the electrode end and the furnace material is used as a heat source to melt the furnace material for steelmaking. Some other smelting furnaces for materials such as yellow phosphorus, industrial silicon, and abrasives also use graphite electrodes as conductive materials. Graphite electrodes have a wide range of applications in other industrial sectors due to their excellent and special physical and chemical properties. The raw materials for producing graphite electrodes include petroleum coke, needle coke, and coal tar pitch.
