China UHP 500 * 2100mm graphite electrode for eaf
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,ultra high power and square electrode. The range of diameters covers from 200mm to 700mm. Our products own the following characteristics:low electric resisitivity, good electric and thermal conductivity,high oxidation resisitance, greater resisitance to thermal and mechanical shock,high mechanical strength, high machining accuracy.
We can produce regular power, high power, and ultra high power graphite electrodes of Φ300-800mm according to customers requirements.
