product details

Introduction: graphite electrode, mainly petroleum coke, needle coke as raw material, coal pitch as binder, calcination, ingredients, kneading, molding, baking and graphitization, machining and made, which is released in electric arc furnace in the form of arc conductor of electricity to heat melting furnace charge, graphite electrode with low resistivity,graphite electrode good conductivity, graphite electrode low ash, graphite electrode uniform and graphite electrode compact structure, good oxidation resistance, high mechanical strength, etc.
