good price fg uhp graphite electrode rp700mm hp 500 graphite electrode with nipples
400mm regular impregnated graphite electrode for arc furnaces
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, our products get the characteristics that low resistivity, good electrical conductivity, low ash, compact structure, good anti oxidation and high mechanical strength.
Graphite Electrode is the best conductive material for electric arc furnace and smelting furnace. High quality needle coke in HP&UHP graphite electrode ensure the electrode application is perfect. It is presently the only available product that has the high levels of electrical conductivity and the capability of sustaining the extremely high levels of heat generated in the demanding environment.
