Graphitized Petroleum Coke (GPC) yog cov khoom siv tseem ceeb hauv kev lag luam metallurgical, dav siv los ua cov pa roj carbon monoxide (recarburizer) hauv steelmaking thiab casting txheej txheem. Nws yog tsim los ntawm high-temperature graphitization ntawm roj av coke ntawm 2,500-3,500 ° C, tus cwj pwm los ntawm nws cov ntsiab lus siab ruaj khov, tsis muaj leej faj, thiab tsis muaj impurity. GPC paub txog nws qhov kev nqus tau siab, kev ua haujlwm ruaj khov, thiab kev ua haujlwm zoo hauv kev txo cov khoom tsis zoo xws li sulfur thiab nitrogen hauv cov hlau molten. Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev tsim cov hlau zoo, cam khwb cia hlau, thiab alloys.
