Product Introduction
Graphite electrode product 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, according to its quality index, can be divided into ordinary power, high power and high power.
