Functions and advantages

The graphite electrodes include: regular power, highpower,ultra high power and square electrode. The range of diameters covers from 300mmto 800mm. Our products own the following characteristics: low electric resistivity, goodelectric and thermal conductivity, high oxidation resistance, greater resistance to thermaland mechanical shock, high mechanical strength, high machining accuracy.

Main uses

Graphite electrode is made from the domestic first petroleum coke and high quality needlecoke and widely used in the electric arc furnaces for production of alloy steels, metal andother nonmetallic materials,etc.
