High Power Graphite Electrodes For Arc Furnaces Of Steel Making

 

Graphite electrode is made from the domestic first class 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 800mm. Our products own the following characteristics: low electric resistivity, good electrical and thermal conductivity, high oxidation resistance, greater resistance to thermal and mechanical shock, high mechanical strength, high machining accuracy.
CNBM and its partner have 4 production bases and the annual production capacity of graphite electrodes is 60,000 MT.
