I-ejenti yokucwenga i-aluminium, eyaziwa nangokuthi ashintsha, iyingxenye ebalulekile yenqubo yokucwenga i-aluminium.Idlala indima ebalulekile ekuhlanzeni i-aluminium encibilikisiwe nokukhipha ukungcola ukuze kuthuthukiswe ikhwalithi yomkhiqizo wokugcina.
Inhloso eyinhloko ye-ejenti yokucwenga i-aluminium ukusiza ukukhishwa kokungcola okuhlukahlukene okukhona ku-aluminium, njenge-magnesium, i-silicon, nokunye ukungcola kwensimbi.Lokhu kungcola kungaba nomthelela omubi kuzakhiwo zemishini, ukubukeka, nokusebenza kukonke kwe-aluminium.
Ama-agent okucwenga i-aluminium ngokuvamile akhiwa ingxube kasawoti nezinhlanganisela ze-fluoride.Ukukhethwa kwezinhlanganisela ezithile kuncike ekungcoleni okukhona kanye nomphumela oyifunayo wenqubo yokucwenga.Izinhlanganisela ezivame ukusetshenziswa zihlanganisa i-cryolite (Na3AlF6), i-fluorspar (CaF2), i-alumina (Al2O3), nosawoti abahlukahlukene.
Lapho i-agent yokucwenga i-aluminium yethulwa ku-aluminium encibilikisiwe, yenza ungqimba lwe-slag phezulu.I-slag isebenza njengesithiyo esivikelayo phakathi kwensimbi encibilikisiwe nomkhathi ozungezile.Lesi sithiyo sisebenza ngezinhloso eziningi.Okokuqala, ivimbela i-aluminium ukuthi ingahlangani nomoya-mpilo, ngaleyo ndlela inciphise amathuba okuba ne-oxidation.Ukwengeza, ungqimba lwe-slag lukhuthaza ukuhlukaniswa kokungcola kusuka ku-aluminium encibilikisiwe, okuvumela ukuba kukhishwe kalula.
Inqubo yokucwenga ibandakanya ukulawula ngokucophelela izinga lokushisa nokwakheka kwe-aluminium encibilikisiwe ukuze kuthuthukiswe ukusebenza kahle kwe-ejenti yokucwenga i-aluminium.Njengoba ukungcola kusabela ngokuguquguquka, kwakha inhlanganisela enamaphuzu ancibilikayo aphezulu kunalawo ancibilikisiwe.i-aluminium.Ngenxa yalokho, lezi zinhlanganisela zishona phansi ku-crucible noma zintante phezulu njengamanzi, okwenza kube lula ukuzihlukanisa ne-aluminium ehlanzekile.
Inani le-ejenti yokucwenga i-aluminium edingekayo lincike ezintweni ezihlukahlukene, njengokwakheka nenani lokungcola, izinga elifiswayo lokuhlanzeka, kanye nendlela ethile yokucwenga esetshenzisiwe.Kubalulekile ukulinganisa phakathi kokusebenzisa inani elanele lokuguquguquka ukuze uzuze ukuhlanzwa okusebenzayo kuyilapho unciphisa izindleko.
Ukusetshenziswa ngempumelelo kwe-ejenti yokucwenga i-aluminium kubangela i-aluminiyamu ehlanzekile enezakhiwo ezithuthukisiwe zemishini, isiphetho esithuthukisiwe sendawo, kanye nokunciphisa amathuba okuba sengozini yokuba sengozini.I-aluminium ecolisisiwe ingasetshenziswa ezimbonini eziningi, ezihlanganisa ezezimoto, i-aerospace, ezokwakha, zokupakisha, nezikagesi.
Kafushane, i-ejenti yokucwenga i-aluminium iyingxenye ebaluleke kakhulu enqubweni yokucwenga i-aluminium.Ivumela ukukhishwa kokungcola, ithuthukise ikhwalithi yomkhiqizo wokugcina, futhi iqinisekisa ukuthi i-aluminium ihlangabezana nezindinganiso ezidingekayo zezinhlelo zayo ezihlosiwe.
