Umkhiqizi we-Graphitized petroleum coke (GPC)

I-graphite petroleum coke isetshenziswa kabanzi njengesithuthukisi sekhabhoni embonini yokwenza insimbi kanye nokuphotha ngokunemba, njengomfuyi embonini ye-foundry, njenge-ejenti yokunciphisa embonini ye-metallurgical kanye nezinto eziphikisayo. I-graphite petroleum coke ingakhuthaza i-nucleation ye-graphite esixazululweni sensimbi, yandise inani le-ductile iron futhi ithuthukise ukuhlelwa kanye nezinga le-grey cast iron. Ngokubuka isakhiwo esincane, i-graphite petroleum coke inezici ezilandelayo: Okokuqala, okuqukethwe kwe-ferrite kwe-ductile iron kungandiswa kakhulu ngaphandle kokusebenzisa iziqinisi ze-pearlite; Okwesibili, isilinganiso se-graphite enobunjwa obungu-V kanye no-VI-shape singandiswa ngesikhathi sokusetshenziswa; Okwesithathu, uma kuqhathaniswa nokuthuthukisa ukuma kwe-nodular ink, ukwanda okukhulu kwenani le-nodular ink kunganciphisa ukusetshenziswa kwe-nucleating agents ezibizayo ekulungiseni kahle kamuva, okuholela ekongeni okukhulu kwezindleko.
