Graphite electrode is a kind of high temperature resistant graphite conductive produced by a series of processes such as kneading, molding, roasting, impregnation, graphitization, and mechanical processing by using petroleum coke and needle coke as aggregates and coal pitch as binder. Material.

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. 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. Utilizing the excellent and special physical and chemical properties of graphite electrodes, it also has a wide range of uses in other industrial sectors.

The raw materials for the production of graphite electrodes are petroleum coke, needle coke and coal tar pitch.

Petroleum coke is a combustible solid product obtained by coking petroleum residue and petroleum pitch. The color is black and porous, the main element is carbon, and the ash content is very low, generally below 0.5%. Petroleum coke belongs to the category of easily graphitized carbon. Petroleum coke is widely used in chemical, metallurgical and other industries. It is the main raw material for the production of artificial graphite products and carbon products for electrolytic aluminum.
