Emkhakheni wezimboni ezisezingeni eliphezulu, ukusebenza kwezinto ezibonakalayo kunquma ngokuqondile ukuzinza nokusebenza kahle kokukhiqiza.Izitini eziphezulu ze-alumina refractory, njengoba izinto eziphikisayo zekhwalithi ephezulu kakhulu ezenziwe nge-alumina bauxite ephezulu, seziphenduke inketho ekahle ezimbonini eziningi ezisezingeni eliphezulu ngokusebenza kwazo okuvelele, zivikela ukuthuthukiswa kwe-metallurgy yomhlaba wonke, izinto zokwakha, amakhemikhali nezinye izimboni.
Izinzuzo eziyinhloko zezitini eziphezulu ze-alumina refractory zisukela ekwakhiweni kwazo okuyingqayizivele kanye nenqubo yokukhiqiza. Lezi zitini zenziwe nge-high-alumina bauxite clinker enokuqukethwe kwe-alumina okungengaphansi kwama-48% njengeqoqo, kuhlanganiswe nezibophezelo ngezilinganiso ezihlukene, bese kwakhiwa, zomiswe, futhi zishiswe emazingeni okushisa aphezulu. Izitini eziphezulu ze-alumina refractory zinokuphikisa okuhle kakhulu, ezikwazi ukumelana namazinga okushisa aphezulu asukela ku-1770°C kuya ku-1790°C. Ngisho nasezindaweni eziphakeme kakhulu zokushisa, bangagcina ubuqotho besakhiwo, bamelane ngokuphumelelayo nokuguguleka kwamazinga okushisa aphezulu kumishini. Ukushisa kwabo okuhle kokuthambisa umthwalo kuqinisekisa ukuthi abajwayele ukuguquguquka nokuwa ngaphansi kwengcindezi ethile kanye namazinga okushisa aphezulu, okuhlinzeka ngeziqinisekiso ezithembekile zokusebenza okuzinzile kwemishini yokushisa ephezulu. Ukwengeza, izitini eziphezulu ze-alumina refractory zinokuphikiswa okuhle kakhulu kokushisa okushisayo, okubavumela ukuba balondoloze ukusebenza okuzinzile ngesikhathi sokushintsha kwezinga lokushisa njalo, ukunciphisa ukuqhekeka nokusabalalisa okubangelwa ukucindezeleka okushisayo nokwandisa impilo yabo yesevisi. Futhi banokumelana okuqinile namakhemikhali ahlukahlukene. Kungakhathaliseki ukuthi i-slag enqubweni ye-metallurgical noma amagesi abolayo ekukhiqizeni amakhemikhali, kunzima ukuwenza umonakalo omkhulu kuwo.
Izitini eziphezulu ze-alumina refractory zinezinhlobonhlobo zezicelo. Embonini ye-metallurgical, ziyizinto eziyinhloko zokwenziwa kweziko lokukhanda insimbi, iziko lokwenza insimbi, nezithando zokushisa kabusha. Bangakwazi ukumelana ngokuphumelelayo nokuguguleka kwensimbi encibilikisiwe enezinga eliphezulu lokushisa eliphezulu kanye ne-slag, ukuqinisekisa inqubekelaphambili eshelelayo yenqubo yokuncibilikisa kanye nokwenza ngcono impilo yenkonzo yemishini nokusebenza kahle kokukhiqiza. Embonini yezinto zokwakha, izitini eziphezulu ze-alumina refractory zivame ukusetshenziswa emishinini efana nosimende ojikelezayo weziko kanye neziko lokuncibilikisa ingilazi. Ezindaweni ezinamazinga okushisa aphezulu, ukukhuculula ukugeleza komoya okunesivinini esikhulu, nokuhuzuka kwezinto ezibonakalayo, zisengakwazi ukugcina ukusebenza kahle, zisekela ukusebenza okuzinzile kokukhiqizwa kwezinto zokwakha. Embonini yamakhemikhali, izitini eziphezulu ze-alumina refractory zidlala indima ebalulekile ezithandweni zokusabela ezisezingeni lokushisa eliphezulu kanye namagesi. Ngokumelana nokugqwala kwamakhemikhali okuhle kakhulu, baqinisekisa ukuphepha nokusebenza kahle kwenqubo yokukhiqiza amakhemikhali
Sihlome ngemishini yokukhiqiza esezingeni eliphezulu kanye nohlelo oluqinile lokulawula ikhwalithi. Sonke isixhumanisi, kusukela ekuthengeni impahla eluhlaza kuya ekulethweni komkhiqizo oqediwe, siqashwe ngokucophelela. Ngokwamukela izinqubo zokukhiqiza ezihamba phambili emhlabeni wonke, siqinisekisa ukuthi ikhwalithi yezitini eziphikisayo ze-alumina ephezulu ihlangabezana namazinga omhlaba. Ngesikhathi esifanayo, siphinde sinikeze ukwesekwa kobuchwepheshe obuchwepheshile kanye nezinsizakalo eziphelele zangemuva kokuthengisa. Ngokwezidingo ezihlukene zamakhasimende, sinikeza izixazululo eziqondene nawe ukuze siqinisekise ukuthi izitini eziphezulu ze-alumina refractory zisebenza kahle kakhulu ekusebenzeni okungokoqobo.
Ukukhetha izitini zethu eziphezulu ze-alumina refractory kusho ukukhetha ikhwalithi nokuthembeka. Noma ngabe udinga ukuthenga ngesilinganiso esikhulu noma izixazululo zezinto ezibonakalayo eziphikisayo, singahlangabezana nezidingo zakho. Samukela ngokufudumele amakhasimende avela emhlabeni wonke ukuthi axhumane nathi futhi asebenze ndawonye ukuze sakhe ikusasa eliqhakazile lemboni yezinga lokushisa eliphezulu!
