Graphite electrode mainly petroleum coke, needle coke as raw material, coal asphalt binder, calcination, ingredients, kneading, molding, baking and graphitization, machining and made, which is released in electric arc furnace in the form of arc conductor of electricity to heat melting furnace charge, according to its quality index, can be divided into ordinary power graphite electrode, high power graphite electrode and ultra high power graphite electrode.

The main raw material for petroleum coke, graphite electrode production ordinary power graphite electrode can add a small amount of pitch coke, sulphur content in petroleum coke and pitch coke can't exceed 0.5%. Production of high power or high power graphite electrode and needle coke is needed. The main raw material for petroleum coke in the aluminium anode production, and control the sulfur content is not more than 1.5% ~ 2%, petroleum coke and pitch coke should comply with the relevant national quality standards.
