Graphite electrode is one of the most important metallurgical products, mainly used as conductive material in electric arc furnace for metallurgy production. UHP graphite electrodes are mainly used for steelmaking high-power and ultra-high power electric furnaces.


Raw Material
The main raw materials of ultra-high-power graphite electrodes are needle coke, high-quality calcined petroleum coke, high-temperature modified pitch ( as binders), and special impregnating pitch (as impregnating agents). The auxiliary materials are metallurgical coke, quartz sand, etc.


Production Process
Graphite electrode is produced through a series of process such as calcination of raw materials, pressing, baking, impregnation, graphitization, and machining. The electrode body adopts a one-dip and two-baked production process, and the electrode nipple adopts a two-dip and three-baked process.
