The graphite electrode is made from the raw materials of high quality petroleum coke, needle coke and coal tar pitch and other low ash materials,through the processing of calcining,burden,kneading,forming,baking,impregnation with pressure. graphitization in high temperature of 3000℃and maching. Graphite electrode is wideiy used in EAF and RKEF to smelting alloy steel,yellow phosphorus,industrial silicon,brown fused alumina and other alloy and non-metal material. the are the main parts of the material industry.shida brand graphite electrodes are RP ,HP,UHP,and different size. The 600mm and larger size UHP graphite electrodes are quite popular in domestic and overseas markets.
