Graphite electrode is a kind of high temperature resistant graphite conductive material, which is made of petroleum coke, pitch coke as granular material, coal pitch as binder, through} kneading, molding, roasting, graphitization and machining. Graphite electrode is an important high-temperature conductive material for electric furnace steelmaking. It inputs electric energy to the electric furnace through graphite electrode. It uses the high temperature caused by electric arc between the electrode end and the furnace charge as the heat source to melt the furnace charge for steelmaking.
Other electric smelting or electrolysis equipment often uses graphite electrode as the conductive material. In 2000, the world consumed about 1 million tons of graphite electrode, and China consumed about 250000 tons of graphite electrode in 2000. Using the excellent physical and chemical properties of graphite electrode, it has a wide range of uses in other industrial sectors. Carbon products industry, which mainly produces graphite electrode, has become an important component of the current raw material industry.
