I-petroleum coke ingumkhiqizo ophuma ekuhlanzeni uwoyela. Ingumkhiqizo oqinile okhiqizwa yiyunithi ye-coking ephuzile enamafutha asele njengezinto zokusetshenziswa. Isetshenziswa kabanzi ku-aluminium ye-electrolytic, ingilazi, insimbi, i-silicon yensimbi kanye neminye imikhakha. Ingumkhiqizo ongasetshenziswa kabusha emikhakheni eminingi. Iyini ukusetshenziswa kwe-petroleum coke enokuqukethwe okuhlukile kwesulfure? Enqubweni yokufaka i-petroleum coke, i-petroleum coke powder enobunono obuhlukile ingakhiqizwa ngokusebenzisai-coke kaphethiloli iRaymond millukuhlangabezana nezidingo ezahlukahlukene zezimboni ezahlukene.

Ikhwalithi yemikhiqizo ye-petroleum coke ithintwa kakhulu yizinhlobonhlobo zamafutha angahluziwe acutshungulwa yifektri. Iningi le-sulfur kanye nokungcola kumafutha angahluziwe kucebile ku-petroleum coke. I-petroleum coke ingahlukaniswa ibe yi-sulfur coke ephansi, i-sulfur coke ephakathi nendawo kanye ne-sulfur coke ephezulu ngokwezinga le-sulfur. Kodwa-ke, iyini ukusetshenziswa kwe-petroleum coke enokuqukethwe kwe-sulfur okuhlukile? Umkhiqizo we-petroleum coke uningi. Iningi le-petroleum coke lingasetshenziswa njengophethiloli wokuncibilikisa insimbi ngemva kokucutshungulwa yiumshini wokugaya i-coke kaphethiloli umshini. I-petroleum coke (i-needle coke) enekhwalithi enhle ingasetshenziswa futhi njengezinto zokusetshenziswa zokugcina amandla ukuze kulungiswe i-graphite yokwenziwa noma i-carbon evuvukele, ngaleyo ndlela kwandiswe inani elengeziwe le-petroleum coke.

I-petroleum coke enokuqukethwe okuphansi kwe-sulfur ingasetshenziswa njengezinto zokusetshenziswa zokwenza ama-electrode kuma-smelters. Isitshalo sekhabhoni sisebenzisa i-petroleum coke, ukusetshenziswa kwayoi-coke kaphethiloli iRaymond millukukhiqiza i-anode paste yesitshalo se-aluminium, futhi kukhiqiza i-graphite electrode yesitshalo sensimbi nesensimbi. Okuqukethwe kwe-sulfur ye-petroleum coke kuthinta ukusetshenziswa kwe-coke kanye nekhwalithi yemikhiqizo yekhabhoni eyenziwe nge-coke. Ikakhulukazi ekwakhiweni kwe-graphite electrode, okuqukethwe kwe-sulfur kuyinkomba ebaluleke kakhulu. Okuqukethwe kwe-sulfur okuphezulu kakhulu kuzothinta ngqo ikhwalithi ye-graphite electrode futhi kuthinte nekhwalithi yokwenza insimbi. Emazingeni okushisa aphezulu ngaphezu kwama-500 ℃, i-sulfur ku-graphite electrode izobola. I-sulfur eningi kakhulu izokwandisa i-electrode crystal, okubangela ukuthi i-electrode inciphe futhi ikhiqize imifantu. Ezimweni ezimbi kakhulu, i-electrode ingasuswa. Ekukhiqizweni kwe-graphite electrode, okuqukethwe kwe-sulfur kwe-petroleum coke kuzothinta ukusetshenziswa kwamandla. Ukusetshenziswa kwamandla kwe-petroleum coke ene-sulfur engu-1.0% cishe kungaphezu kuka-9% kunalokho kwe-petroleum coke ene-sulfur engu-0.5% ngethani. Lapho i-petroleum coke isetshenziswa njengezinto zokusetshenziswa ze-anode paste, okuqukethwe kwayo kwe-sulfur nakho kunomthelela omkhulu ekusetshenzisweni kwamandla.

Uchungechunge lwe-HC i-coke kaphethiloli iRaymond milliyimishini yokugaya enkulu, esebenza kahle kakhulu futhi enobungani nemvelo eyakhiwe ngokuzimela yiGuilin Hongcheng Mining Equipment Manufacturing Co., Ltd. Umshini oyinhloko usebenzisa isakhiwo sesisekelo sokugaya esihlanganisiwe, futhi ungasebenzisa isisekelo sokudambisa. Ngesikhathi esifanayo, kusetshenziswa uhlelo lokushaya uthuli olungaxhunyiwe ku-inthanethi noma uhlelo lokuqoqa uthuli lwe-afterwind, olunomphumela oqinile wokuhlanza uthuli, impilo ende yesevisi yesikhwama sokuhlunga, kanye nokusebenza kahle kokuqoqa uthuli kufika ku-99.9%, okuqinisekisa umphumela wokuvikela imvelo. Ingasetshenziswa njengokucubungula nokukhiqizwa kweuphethiloliumshini wokugaya i-coke, futhi ubuncane bomkhiqizo oqediwe bungafinyelela ku-38-180μm.

Uma ufuna ukwazi okwengeziwe nge-uphethiloliumshini wokugaya i-coke kanye nezinye izinkinga ezihlobene, sicela uxhumane ne-HCM.
