Calcined petroleum coke (CPC) yog cov khoom siv roj carbon ntau tau los ntawm cov roj av coke, ib qho khoom siv los ntawm kev ua kom cov roj crude. Cov txheej txheem ntawm calcining muaj xws li cua sov roj av coke nyob rau hauv ib tug rotary kiln ntawm kub ntawm 1200-1400 degree (kwv yees 2200-2550 degree F), uas tshem tawm cov volatile tshuaj thiab tsav tawm impurities, uas ua rau cov khoom uas muaj cov pa roj carbon ntau dua thiab tsawg impurities.
CPC feem ntau yog siv rau hauv kev tsim cov txhuas, hlau, thiab titanium dioxide, vim nws ua haujlwm tseem ceeb hauv kev tsim cov anodes rau txhuas smelting. Lub siab purity thiab ntom carbon qauv ua calcined petroleum coke ib qho khoom siv zoo tagnrho rau lub hom phiaj no, vim nws muaj cov hluav taws xob zoo heev thiab tuaj yeem tiv taus qhov kub thiab txias ib puag ncig hauv cov txheej txheem electrolytic txo.
Tsis tas li ntawd, CPC tuaj yeem siv rau hauv kev tsim cov khoom siv hluav taws xob rau hluav taws xob arc rauv hauv kev lag luam steel, thiab hauv kev tsim khoom ntawm lwm cov khoom lag luam uas xav tau cov ntsiab lus siab carbon. Qhov zoo ntawm CPC nyob ntawm seb hom roj av coke siv thiab cov txheej txheem calcining nws tus kheej.
