500mm High Power Graphite Electrode
500mm High Power Graphite Electrode with Different Length
Introduction of graphite elctrode
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 (EAF) and ladle furnace (LF).
