Graphite Petroleum Coke Yopangira Iron Iron Casting Foundry

Coke ya petroleum yokhala ndi graphite yoyera kwambiri imapangidwa kuchokera ku coke ya petroleum yapamwamba kwambiri pa kutentha kwa 2500-3500 ℃. Ndi chinthu cha carbon choyera kwambiri, chokhala ndi carbon yokhazikika kwambiri, sulfure yochepa, phulusa lochepa, porosity yochepa ndi zina. Ingagwiritsidwe ntchito ngati carburizer (yowonjezera carbon) kuti ipange chitsulo chapamwamba, chitsulo chopangidwa ndi chitsulo ndi alloys. Ingagwiritsidwenso ntchito ngati chowonjezera mu pulasitiki ndi rabala.
