China Manufacturer RP HP UHP Grade Graphite Electrode For EAF & LF Furnace
Production Description:
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 the 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,ensure the electrode application is perfect. Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes.
Artificial graphite electrode is made of high-quality low ash materials, such as petroleum coke, needle coke and coal pitch.after calcining,burdening,kneading,forming,baking and pressure impregnation, graphitization and then precision machined with professional CNC machining.such of the products own characteristics with low resistivity, good electrical conductivity ,low ash, compact structure,good anti oxidation and high mechanical strength, so it is the best conductive material for electric arc furnace and smelting furnace.
