Description and Application
Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials, coal tar pitch is used as a binder, and are made by calcining, batching, kneading, pressing, roasting, graphitization, and machining. It releases electric energy in the form of electric arc in an electric arc furnace. The conductors used for heating and melting the charge can be divided into ordinary power graphite electrodes, high power graphite electrodes and ultra-high power graphite electrodes according to their quality indicators.
