Calcined Petroleum Needle Coke
Calcined petroleum needle coke is a premium grade of calcined coke with a distinctive needle-like crystalline structure, produced from specific feedstocks and calcination processes. It is primarily used in the manufacture of graphite electrodes for electric arc furnaces in steelmaking. Despite its specialized morphology, it remains a calcined petroleum coke residue and is classified under tariff item 2713.12.00.
