Pakistan FACTBOX-What are graphite electrodes and needle coke?
Petroleum coke is a black or dark gray solid oil with a metallic luster, porous, is a granular carbon consisting of small crystals of graphite, columnar or needle composition. The component of petroleum coke is hydrocarbons. ， Carbon 90-97%, hydrogen 1.5 -8.%. ， Also contains nitrogen, chlorine, sulfur and heavy metal compounds.
Pakistan The Composition of Graphite Electrodes
Graphite electrodes serve to transfer the electrical energy from the power supply to the steel melt in the EAF bath. They are typically made using premium petroleum needle coke, coal tar pitch, and some additives (Fruehan, 1998 ). Specification of needle coke for the manufacture of large diameter graphite electrodes is shown in Table 12.12.
