Wopanga graphitized petroleum coke (GPC).

Graphite petroleum coke chimagwiritsidwa ntchito ngati chowonjezera mpweya m'mafakitale kupanga zitsulo ndi mwatsatanetsatane kuponyera, monga obereketsa mu makampani foundry, monga kuchepetsa wothandizila mu makampani zitsulo ndi monga chuma refractory. Graphite petroleum coke akhoza kulimbikitsa nucleation wa graphite mu chitsulo njira, kuonjezera kuchuluka kwa ductile chitsulo ndi kusintha gulu ndi kalasi ya imvi kuponyedwa chitsulo. Kudzera yaying'ono dongosolo kuonerera, graphite petroleum coke ali makhalidwe awa: Choyamba, ferrite zili ductile chitsulo akhoza kwambiri kuchuluka popanda ntchito pearlite stabilizers; Chachiwiri, gawo la V-woboola pakati ndi VI-woboola pakati graphite akhoza ziwonjezeke pa ntchito; Chachitatu, poyerekeza ndi kuwongolera mawonekedwe a inki ya nodular, kuwonjezeka kwakukulu kwa inki ya nodular kungachepetse kugwiritsa ntchito ma nucleating agents okwera mtengo pakukonza bwino pambuyo pake, zomwe zimapangitsa kuti pakhale ndalama zambiri.
