What is graphite electrode
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. Graphite electrode production of the main raw material for petroleum coke, ordinary power graphite electrode can add a small amount of asphalt coke, petroleum coke and asphalt coke sulfur content can not exceed 0.5%. Needle coke is also needed to produce high - or ultra-high - power graphite electrodes. The main raw material for aluminum anode production is petroleum coke, and control sulfur content is not more than 1.5% ~ 2%, petroleum coke and asphalt coke should meet the relevant national quality standards.
