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.Sanneng 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.
till now, we have production capacity 30,000 tons per year, and we exported graphite electrode to Europe and America near 500 tons per month, and export graphite scrap to Europe 300 tons per month
Now we hope to establish business relationship with you and your company, believe it will come true in near future.
