China Graphite Electrode UHP 350

Artificial Graphite Electrode is made of high-quality low-ash materials, such as needle coke, petroleum coke and coal pitch. After the process of calcining, burdening, kneading, forming, baking, high-pressure impregnation, graphitization and then high-precision CNC machining . The finished products are with characteristics of low resistivity, excellent electric conductivity, low ash, fine inner structure, good anti-oxidation and high mechanical strength, it is the very best conductive material for arc furnace and smelting furnace.
