The graphite electrode is mainly made of petroleum coke and needle coke, and the coal bitumen is used as a binder. It is made by calcination, compounding, kneading, forming, baking, graphitization and machining.
According to its quality indicators, graphite electrodes can be divided into RP graphite electrodes, HP graphite electrodes and UHP graphite electrodes.
Regular Power (RP) :Current density <17A/cm2, which are mainly used in ordinary power electric furnaces such as steel making, silicon refining, and yellowing phosphorus.
High Power (HP): current density of 18 to 25 A/cm2 , and are mainly used in high-power electric arc furnaces for steel making.
Ultra High Power (UHP): current density > 25 A/cm2 , mainly for ultra high power arc furnaces.
