RP HP UHP Graphite Electrode
1.Dia:40-600mm
2.Length:1600-2400mm
Graphite electrode is made from the domestic first petroleum coke and high quality needle coke
and widely used in the electric arc furnaces for production of alloy steels, metal and other
nonmetallic materials, etc.
Applications
Used in steel making, as well as in electric smelting furnace for producing industrial silicon, phosphorus, etc.
