Production Introduction:
Using Coal tar pitch as binder, the Graphite Electrode is mainly made of petroleum coke and Needle Coke through the process of calcination, compounding, kneading, pressing, baking, impregnation, graphitization and maching. It’s a conductor that release electric energy to heat and melt the charge in the EAF or LF. Graphite Electrode possess the characteristics of low electric resistivity, good electrical conductivity, low ash content, uniform structure, good oxidation resistance and high strength.

Applications:
RP Graphite Electrode is mainly used in LF furnaces or submerged arc furnaces to produce steel, ferroalloy, silicon metal, yellow phosphorus and aluminium oxide etc. Rongxing Carbon can supply different diameter of RP Graphite Electrode. So far, our RP Graphite Electrode are exported to Middle East, Spain, Russia, Brazil, Mexico, Argentina and so on.
