Our 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.
The graphite electrodes include regular power, high power, super high power, ultra high power and square
electrode. The range of diameters covers from 200mm to 700mm.
