Graphite Electrodes
Graphite electrode, mainly from the domestic petroleum coke and imported needle coke, is widely used in electric arc furnace,ladle furnace, submerged arc electric furnace for theproduction of alloy steel, metal and nonmetallic materials.
* High density, high temperature resistance, high mechanical strength and strong chemical stability.
* The surface can be treated with anti-oxidation.
* Corrosion resistance, strong acid and alkali resistance.
* Excellent thermal shock resistance, electrical conductivity and thermal conductivity.
* Strong wear resistance and lubricating performance.
* Long service life.
