Ultrahigh graphite electrode
Graphite electrode: mainly using petroleum coke and needle coke as raw materials, coal tar pitch as binder, calcined, proportioned, kneaded, pressed and molded;
It is made by roasting, graphitization and machining. It is a conductive material that releases electric energy in the form of electric arc to heat and melt the burden in the electric arc furnace According to its quality index, it can be divided into ordinary power, high power and ultra-high power. The graphite electrode mainly consists of ordinary work
There are four types of graphite electrodes, i.e. high power graphite electrode, oxidation resistant coating graphite electrode, high power graphite electrode and ultra-high power graphite electrode
It is mainly used for steelmaking in steel works. Silicon plant, foundry, metallurgical smelting.
