I-Graphitized petroleum coke (GPC) Umkhiqizi
I-graphite petroleum coke isetshenziswa kakhulu njengesithuthukisi sekhabhoni embonini yokwenza insimbi kanye nokunemba kokuphonswa kwensimbi, njengomfuyi embonini yokusungula, njenge-ejenti yokunciphisa embonini ye-metallurgical nanjengento ephikisayo. I-graphite petroleum coke ingakhuthaza i-nucleation ye-graphite kusixazululo sensimbi, yandise inani le-ductile iron futhi ithuthukise inhlangano kanye nebanga le-grey cast iron. Ngokubhekwa kwesakhiwo esincane, i-graphite petroleum coke inezici ezilandelayo: Okokuqala, okuqukethwe kwe-ferrite yensimbi ye-ductile kungandiswa kakhulu ngaphandle kokusetshenziswa kwe-pearlite stabilizers; Okwesibili, ingxenye ye-graphite emise okwe-V kanye ne-VI ingandiswa ngesikhathi sokusetshenziswa; Okwesithathu, uma kuqhathaniswa nokuthuthukisa umumo kayinki we-nodular, ukwanda okukhulu kwenani likayinki we-nodular kunganciphisa ukusetshenziswa kwama-nucleating agents abizayo ekulungiseni kahle kamuva, okuholela ekongeni kwezindleko ezinkulu.
