Useage in Aluminum Smlter：Calcinated coke is the main raw material for the production of pre-baked anode, accounting for about 85%. Pre-baked anode is a kind of anode consumption material for smelting aluminum, which bears the functions of electric, thermal and magnetic conductivity in the production process of electrolytic aluminum, and is consumed by participating in electrochemical reaction.

Characters ：The quality of petroleum coke will have a great impact on the quality of the anode, should have high purity, high vibration density, high oxidation resistance, low resistivity, low ash content and low microelement content. Major trace elements that need to be controlled in actual production elements are Si,Fe,Ti, Pb,Ni,V,Na,Ca,S,P, etc.
