Izitini Zomlilo Ezine-Alumina Ephakeme: Isixazululo Esiphezulu Sokujikijela Kwezicelo Zokushisa Okuphezulu Kwezimboni

Ukusebenza kwezitofu zezimboni kuncike kakhulu ezintweni zokwakha eziqinile nezimelana nokushisa. Phakathi kwayo yonke imikhiqizo ephikisayo,izitini zomlilo ze-alumina ephezuluzibhekwa njengenye yezinketho ezithembeke kakhulu zokukhiqiza zanamuhla. Zisetshenziswa kabanzi ekusetshenzisweni kwensimbi, ekukhiqizweni kwesimende, ubunjiniyela bamakhemikhali kanye nasekucutshungulweni kwe-ceramic, izitini eziqinile ze-alumina zigcina ukuzinza okuhle kakhulu kokushisa kanye namandla omshini ngaphansi kwezimo zokushisa eziphakeme kakhulu. Ngokuthuthuka okuqhubekayo kwezindinganiso zokukhiqiza zezimboni, izitini zomlilo ze-alumina eziphakeme ezifanelekile ziye zaba ezibalulekile ekwandiseni impilo yesevisi yesithando somlilo kanye nokunciphisa izindleko zokusebenza kwefektri.

Inzuzo eyinhloko yezitini zomlilo ze-alumina ephezulu ilele ekuquketheni kwazo okuphezulu kwe-alumina oxide, kusukela ku-48% kuya ku-80%. Okuqukethwe okuphezulu kwe-alumina kuthuthukisa kakhulu ukujiya, okuvumela izitini ukuthi zimelane namazinga okushisa asebenzayo aqhubekayo phakathi kuka-1400℃ no-1790℃. Uma kuqhathaniswa nezitini zomlilo zobumba ezijwayelekile, izitini zomlilo ze-alumina eziphezulu kakhulu zinikeza ukumelana nokugqwala okuphezulu, ukumelana nokuguguleka kwe-slag okunamandla kanye nokuqina okumangalisayo kokushaqeka kokushisa. Zimelana nokuqhekeka kanye nokuguquguquka ngaphansi kokushintshashintsha kwezinga lokushisa okuvamile, zivimbela ngempumelelo ukulimala kwendwangu yesithando futhi zinciphise ukulungiswa okungahleliwe kanye nesikhathi sokungasebenzi kokukhiqiza.

Izitini zethu zomlilo ze-alumina eziphakeme zikhiqizwa ngezinto zokusetshenziswa ze-bauxite ezicwengisisiwe ngokushisa okuphezulu kanye nokuhlolwa kwekhwalithi okuqinile, okuhambisana ngokugcwele nezindinganiso zomhlaba wonke zokungaguquki kwezimboni. Sinikeza uhla oluphelele lwezitini zokungaguquki ezijwayelekile nezinobukhulu obufanele ama-rotary oil, ama-blast oven, ama-heating oven kanye nemishini ehlukahlukene yokushisa yezimboni. Iqembu ngalinye lokukhiqiza lihlolwa ukuminyana, amandla okucindezela, ukungaguquki kanye nezinye izinkomba ezibalulekile ukuqinisekisa ikhwalithi ezinzile nethembekile kubathengi bezimboni zomhlaba wonke.

Ukusebenza kahle kwezindleko kuyisizathu esiyinhloko sokuthi izitini zomlilo ze-alumina eziphakeme zamukelwe kabanzi emhlabeni jikelele. Uma kuqhathaniswa nezinto zokwakha ezihlanganisiwe ezisezingeni eliphezulu, izitini ze-alumina eziphakeme zilinganisela ukusebenza okuphezulu kanye namanani okuncintisana. Isikhathi sazo senkonzo esandisiwe sinciphisa imvamisa yokufakwa esikhundleni kwezinto, izindleko zabasebenzi kanye nokulahlekelwa komkhiqizo, okwenza zibe yisisombululo sokushisa esizinzile nesingabizi kakhulu kanye nesisombululo sokungaguquguquki samabhizinisi amancane, aphakathi namakhulu okukhiqiza.

Njengoba ukukhiqizwa kwezimboni emhlabeni wonke kuqhubekela phambili ekusebenzeni kahle okuphezulu kanye nokusetshenziswa kwamandla okuphansi, isidingo semakethe sezinto eziqinile eziqinile siyaqhubeka nokukhula. Abakhiqizi bezitini eziqinile eziqinile ezisebenzisa i-aluminium bayaqhubeka nokwenza ngcono amasu okukhiqiza ukuze bathuthukise ukusebenza kokushisa nokuqina komkhiqizo. Kubakhiqizi bezimboni abafuna izinto eziqinile eziqinile ezisebenzisa i-furnace, izitini eziqinile eziqinile ezivivinywe kahle, ezihambisana ngokugcwele futhi ezenziwe ngezifiso zihlala ziyisinqumo esingcono kakhulu sokukhulisa ukusebenza kahle kokukhiqiza kanye nokutshalwa kwezimali okuphansi kwesikhathi eside.

Imishini yesithando somlilo ehlukene kanye nezimo zokusebenza zidinga okuqukethwe kwe-alumina okwenzelwe wena, ubukhulu, ukumelana nokucindezelwa kanye nemingcele yokumelana nokushisa. Uma uhlela ukulungiswa kwesithando somlilo, ukuthengwa kwezinto eziphikisayo noma ukushintshwa kokulungiswa kwemishini, zizwe ukhululekile ukuxhumana nathi nganoma yisiphi isikhathi. Sisekelwa izinhlelo zokukhiqiza ezivuthiwe kanye namaqembu ochwepheshe ochwepheshe, singafanisa amamodeli ezitini zomlilo ze-alumina eziphakeme kakhulu ngokwezimo zakho zokusebenza ezihlukile kanye nemingcele yesithando somlilo, sinikeze izixazululo zamahhala ezenzelwe wena, izingcaphuno ezinembile kanye nezinsizakalo zokuthenga ezitholakala endaweni eyodwa ukusiza amafektri ukulawula izindleko nokuthuthukisa ukuzinza kokusebenza kwesithando somlilo.
