UHP Graphite Electrode

Products Description

Graphite electrode is made from the domestic first-class petroleum coke and good 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.
