1. Incazelo yomkhiqizo:

I-semi-graphitized petroleum coke iwumkhiqizo we-coke ye-petroleum e-calcined njengento eluhlaza, efakwa esithandweni se-graphitizing, emva kokushisa okuphezulu kwe-graphitization, ukusabela ngokomzimba namakhemikhali nokususwa kwesibabule nomlotha nokunye ukungcola.Kwesinye isikhathi ibizwa nge-artificial graphite, esetshenziswa kwi-ejenti ye-carburizing, evame ukwaziwa njenge-ultra low sulfur/low carburizing agent.

Umkhiqizo we-petroleum oqinile onamafutha noma ongalufifi oqinile onokucwebezela kwensimbi kanye ne-porosity, ehlanganisa amakristalu e-graphite amancane akha imizimba ye-carbon granular, columnar, noma efana nenaliti.I-petroleum coke iyi-hydrocarbon, equkethe i-carbon engaphezu kuka-99%, kodwa futhi iqukethe i-nitrogen, i-chlorine, isulfure kanye nezinhlanganisela zensimbi ezisindayo.

2. Imvelo nokusetshenziswa:

I-semi-graphitized petroleum coke isetshenziswa kabanzi embonini.Isetshenziselwa i-metallurgy, casting kanye nokukhipha okunembayo njenge-ejenti yokungcwaba.Isetshenziselwa ukwenza ukushisa okuphezulu kwe-crucible yokuncibilikisa, okokugcoba embonini yemishini, ukwenza i-electrode kanye nepencil lead;Isetshenziswa kabanzi ezintweni eziphikisayo ezisezingeni eliphezulu kanye nezingubo embonini ye-metallurgical, i-stabilizer yezinto zomlilo zezimboni zamasosha, ipensela ehola embonini yokukhanya, ibhulashi le-carbon embonini kagesi, i-electrode embonini yebhethri, i-catalyst embonini kamanyolo wamakhemikhali, njll. I-Graphitized petroleum coke isetshenziswa embonini ye-graphite, smelting kanye namakhemikhali ngokwekhwalithi yayo.Isibabule esiphansi, i-coke ephekwe esezingeni eliphezulu njenge-coke yenaliti, esetshenziswa ikakhulukazi ekwenzeni ama-electrode e-graphite anamandla aphezulu kanye neminye imikhiqizo yekhabhoni ekhethekile;I-needle coke iyinto ebalulekile ekuthuthukiseni ubuchwepheshe obusha bokwenza insimbi yesithando somlilo kagesi embonini yokwenza insimbi.Isibabule esimaphakathi, i-coke ejwayelekile ephekiwe, esetshenziswa ekuncibilikiseni i-aluminium.Isibabule esiphezulu, i-coke evamile, isetshenziselwa ukukhiqizwa kwamakhemikhali, njengokwenziwa kwe-calcium carbide, i-silicon carbide, njll., kodwa futhi njengophethiloli wensimbi.Iningi le-petroleum coke ekhiqizwa eShayina i-low-sulfur coke, esetshenziselwa ukwenza i-aluminium ne-graphite.

I-electrode ye-graphite yenziwe kakhulu ngekhwalithi ephezulu ye-petroleum coke, inaliti ye-coke njengempahla eluhlaza, i-asphalt yamalahle njenge-binder, ngokubala, ukuxubha, ukuxova, ukucindezela, ukugazinga, ukuxubha, ukwenza imishini nokwenza, ku-arc esithandweni somlilo ngendlela yamandla kagesi. ukukhulula amandla kagesi esithandweni somlilo sokushisa nokuncibilika komqhubi, ngokusho kwenkomba yayo yekhwalithi, ingahlukaniswa ibe amandla avamile, amandla aphezulu kanye namandla aphezulu aphezulu.
