Graphite Electrode HP 300 To 450mm
Graphite electrodes are a high temperature resistant graphite conductive refractory material used in the metallurgical industry.
Graphite Electrode is made of petroleum coke, bituminous coke as aggregates, coal tar pitch as binders, after raw material been calcined , rushing and milling,batching,kneading,molding,roasting,impregnation,graphitization and machining, which is also known as artificial graphite electrodes .
