Coke ya petroleum yokhala ndi graphitized yoyera kwambiri imapangidwa kuchokera ku coke ya petroleum yapamwamba kwambiri pa kutentha kwa 2,500-3,500°C. Monga chinthu cha carbon choyera kwambiri, ili ndi mawonekedwe a carbon yokhazikika kwambiri, sulfure yochepa, phulusa lochepa, porosity yochepa ndi zina zotero. Ingagwiritsidwe ntchito ngati chokweza carbon (Recarburizer) kuti ipange chitsulo chapamwamba kwambiri, chitsulo chopangidwa ndi alloy ndi alloy. Ingagwiritsidwenso ntchito mu pulasitiki ndi rabara ngati chowonjezera.
Semi Coke imapangidwa kuchokera ku malasha apamwamba a anthracite, omwe amapangidwa ndi kutentha kwambiri (1300℃), omwe amagwiritsidwa ntchito kwambiri popanga calcium carbide, kupanga ma ferroalloys kapena kusungunula zitsulo zopanda ferrous, kupanga kapena mafakitale ena okhudzana ndi zitsulo, chifukwa cha mawonekedwe ake apadera a thupi ndi mankhwala: kuchuluka kwa kaboni kokhazikika, sulfure yochepa komanso kuchuluka kwa phosphorous kochepa.
Poyerekeza ndi zinthu ziwirizi, sulfure yomwe ili mu Semi GPC ndi 0.1-0.3%, sulfure yomwe ili mu GPC ndi 0.03-0.05%, N yomwe ili mu Semi GPc ndi 500ppm, ndipo GPC N ndi 300ppm, koma zonsezi zingagwiritsidwe ntchito popanga zitsulo ngati recarburizer ndipo mtengo wa Semi GPC ndi wotsika kwambiri. Ngati mukufuna kudziwa zambiri za zinthu ziwirizi, chonde onani adilesi yolumikizirana pansipa:
