RP Graphite Electrode 

Advantages of Graphite Electrodes

Graphite electrode mainly uses petroleum coke and needle coke as raw materials, coal pitch as binder, and is made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. It releases electric energy in the form of electric arc in electric arc furnace The conductor that heats and melts the charge can be divided into ordinary power graphite electrode, high power graphite electrode and ultra-high power graphite electrode according to its quality index.

The main raw material for the production of graphite electrodes is petroleum coke. A small amount of asphalt coke can be added to ordinary power graphite electrodes. The sulfur content of petroleum coke and asphalt coke cannot exceed 0.5%. Needle coke is also needed when producing high-power or ultra-high-power graphite electrodes. The main raw material for the production of aluminum anodes is petroleum coke, and the sulfur content should be controlled not more than 1.5% to 2%. Petroleum coke and asphalt coke should meet the relevant national quality standards.
