The graphite electrode is mainly made of petroleum coke and needle coke, and the coal bitumen is used as a binder. Graphite Electrodes has good electrical properties and chemical resistance, which has high mechanical strength at high temperature and good seismic performance.

It is good conductor of heat and electricity, widely used in electric arc furnace steelmaking, refining furnace, ferroalloy production, industrial silicon, phosphorus corundum and other submerged arc furnace with an electric arc furnace smelting and other high temperature furnace.
