Emkhakheni wezimboni ezishisa kakhulu, ukusebenza kwezinto zokwakha kunquma ngqo ukuzinza nokusebenza kahle kokukhiqiza.Izitini eziqinile ze-alumina ephezulu, njengoba izinto ezisezingeni eliphezulu eziphikisayo ezenziwe kakhulu nge-bauxite ene-alumina ephezulu, sezibe ukukhetha okuhle kakhulu kwezimboni eziningi ezishisa kakhulu ngokusebenza kwazo okuvelele, okuvikela intuthuko ye-metallurgy yomhlaba wonke, izinto zokwakha, amakhemikhali nezinye izimboni.
Izinzuzo eziyinhloko zezitini eziphikisayo ze-alumina ephezulu zivela ekwakhekeni kwazo okuhlukile kanye nenqubo yokukhiqiza. Lezi zitini zenziwe nge-clinker ye-bauxite ephezulu ye-alumina enokuqukethwe kwe-alumina okungenani ngaphansi kuka-48% njenge-aggregate, kuhlanganiswe nama-binder ngezilinganiso ezahlukene, bese kwakheka, komiswe, bese kushiswa emazingeni okushisa aphezulu. Izitini eziphikisayo ze-alumina ephezulu zinamandla okuphikisa okuhle, zikwazi ukumelana namazinga okushisa aphezulu asukela ku-1770°C kuya ku-1790°C. Ngisho nasezindaweni ezishisa kakhulu, zingagcina ubuqotho besakhiwo, zimelane ngempumelelo nokuguguleka kwamazinga okushisa aphezulu emishinini. Izinga lazo lokushisa elihle lokuthambisa umthwalo liqinisekisa ukuthi aziguquguquki futhi ziwohloke ngaphansi kwengcindezi ethile namazinga okushisa aphezulu, zinikeza iziqinisekiso ezithembekile zokusebenza okuzinzile kwemishini eshisa kakhulu. Ngaphezu kwalokho, izitini eziphikisayo ze-alumina ephezulu zinamandla okuphikisa ukushisa okuhle, okuzivumela ukuthi zigcine ukusebenza okuzinzile ngesikhathi sokushintsha kwezinga lokushisa okuvamile, ukunciphisa ukuqhekeka nokuqhekeka okubangelwa ukucindezeleka kokushisa nokwandisa impilo yazo yokusebenza. Ziphinde zibe nokumelana okuqinile nezinto ezahlukahlukene zamakhemikhali. Kungakhathaliseki ukuthi yi-slag enqubweni ye-metallurgical noma amagesi agqwalisayo ekukhiqizweni kwamakhemikhali, kunzima ukubangela umonakalo omkhulu kuwo.
Izitini ezinamathelayo ze-alumina ephezulu zinezindlela eziningi zokusetshenziswa. Embonini yensimbi, ziyizinto ezibalulekile zezinhlaka zezitofu zokwenza insimbi, izitofu zokwenza insimbi, kanye nezitofu zokufudumeza kabusha. Zingamelana ngempumelelo nokuguguleka kwensimbi encibilikisiwe eshisa kakhulu kanye ne-slag, ziqinisekise inqubekela phambili ebushelelezi yenqubo yokuncibilikisa futhi zithuthukise impilo yesevisi yemishini kanye nokusebenza kahle kokukhiqiza. Embonini yezinto zokwakha, izitini ezinamathelayo ze-alumina ephezulu zivame ukusetshenziswa emishinini efana nama-oven ajikelezayo esimende kanye nezitofu zokuncibilikisa ingilazi. Ezindaweni ezinokushisa okuphezulu, ukukhuhla komoya okusheshayo, kanye nokuguguleka kwezinto, zisengagcina ukusebenza okuhle, zisekele ukusebenza okuzinzile kokukhiqizwa kwezinto zokwakha. Embonini yamakhemikhali, izitini ezinamathelayo ze-alumina ephezulu zidlala indima ebalulekile ezitsheni zokusabela ezishisa kakhulu kanye nama-gasifier. Ngokumelana kwazo okuhle kakhulu nokugqwala kwamakhemikhali, ziqinisekisa ukuphepha kanye nokusebenza kahle kwenqubo yokukhiqiza amakhemikhali.
Sihlonyiswe ngemishini yokukhiqiza ethuthukisiwe kanye nohlelo lokulawula ikhwalithi oluqinile. Zonke izixhumanisi, kusukela ekuthengweni kwezinto zokusetshenziswa kuya ekulethweni komkhiqizo oqediwe, ziqashwa ngokucophelela. Ngokwamukela izinqubo zokukhiqiza ezihamba phambili emhlabeni jikelele, siqinisekisa ukuthi ikhwalithi yezitini eziphikisayo ze-alumina ephezulu ihlangabezana nezindinganiso zomhlaba wonke. Ngesikhathi esifanayo, siphinde sinikeze ukwesekwa kobuchwepheshe obuchwepheshile kanye nezinsizakalo eziphelele ngemuva kokuthengisa. Ngokwezidingo ezahlukene zamakhasimende, sinikeza izixazululo ezenzelwe wena ukuqinisekisa ukuthi izitini eziphikisayo ze-alumina ephezulu zingasebenza kahle kakhulu ezisetshenzisweni ezisebenzayo.
Ukukhetha izitini zethu ezinamathelayo ze-alumina ephezulu kusho ukukhetha ikhwalithi nokuthembeka. Kungakhathaliseki ukuthi udinga ukuthenga okukhulu noma izixazululo zezinto ezinamathelayo zobungcweti, singahlangabezana nezidingo zakho. Samukela ngemfudumalo amakhasimende avela kuwo wonke umhlaba ukuthi asithinte futhi sisebenzisane ukudala ikusasa eliqhakazile embonini eshisa kakhulu!
