Graphite Electrode

Graphite electrodes are widely used in electric arc furnaces for smelting of steel, alloy steel, various alloys and nonmetals. Graphite electrodes supplied by GES always met the requirements of customers with their excellent qualities. Graphite electrodes are used in electric arc furnace and ladle furnace for steel making. Our factories has owned advanced producing technology, height technical force and perfect testing methods. With different types of nipples, our plant can product male and female electrodes, Most of our electrodes exported to USA, UK, Germany, Belgium, France, Japan, South Korea, India, Middle East and Russia.
