Graphite Electrode
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 antioxidation and high mechanical strength, so it is the best conductive material for EAF and smelting furnace.
