Graphite electrodes are used mainly in ladle furnaces, electric-arc furnace steelmaking, Yellow phosphorus furnace, Industrial silicon furnace, or melting copper. They are presently the only products available that have high levels of electrical conductivity and the capability of sustaining the extremely high levels of heat generated in this demanding environment. High-Quality Needle Coke in HP&UHP graphite electrode, ensures the electrode application is perfect. Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes.
