Kwicandelo lemizi-mveliso eshushu kakhulu, ukusebenza kwezinto kumisela ngokuthe ngqo uzinzo kunye nokusebenza kakuhle kwemveliso.Izitena ze-alumina eziphezulu ezirhabaxa, njengoko izixhobo ezinganyangekiyo ezikumgangatho ophezulu ezenziwe nge-bauxite ephezulu ye-alumina, ziye zaba lukhetho olufanelekileyo kumashishini amaninzi ashushu kakhulu ngenxa yokusebenza kwawo okugqwesileyo, okukhusela uphuhliso lwe-metallurgy yehlabathi, izixhobo zokwakha, iikhemikhali kunye nezinye izimboni.
Iingenelo eziphambili zezitena ezichasayo ze-alumina ephezulu zivela kulwakhiwo lwazo olulodwa kunye nenkqubo yokwenziwa. Ezi zitena zenziwe nge-clinker ye-alumina ephezulu ye-alumina enomxholo we-alumina ongaphantsi kwama-48% njenge-aggregate, zidityaniswe nezibopheleli ngobuninzi obahlukeneyo, emva koko zenziwe, zomiswe, kwaye zitshiswe kubushushu obuphezulu. Izitena ezichasayo ze-alumina ephezulu zichasayo kakhulu, ziyakwazi ukumelana nobushushu obuphezulu ukusuka kwi-1770°C ukuya kwi-1790°C. Nokuba zikwiindawo ezinobushushu obuphezulu kakhulu, zinokugcina ulungelelwaniso lwesakhiwo, zixhathise ngempumelelo ukukhukuliseka kobushushu obuphezulu kwizixhobo. Ubushushu bazo obuhle bokuthambisa umthwalo buqinisekisa ukuba aziguquguquki kwaye zidilike phantsi koxinzelelo oluthile kunye nobushushu obuphezulu, zibonelela ngeziqinisekiso ezithembekileyo zokusebenza okuzinzileyo kwezixhobo ezinobushushu obuphezulu. Ukongeza, izitena ezichasayo ze-alumina ephezulu zichasayo kakhulu kubushushu, ezivumela ukuba zigcine ukusebenza okuzinzileyo ngexesha lotshintsho oluqhelekileyo lobushushu, ukunciphisa ukuqhekeka kunye nokuqhekeka okubangelwa kuxinzelelo lobushushu kwaye kwandise ubomi bazo benkonzo. Zikwachasayo kakhulu kwizinto ezahlukeneyo zeekhemikhali. Nokuba yi-slag kwinkqubo ye-metallurgical okanye iigesi ezirhabaxa kwimveliso yeekhemikhali, kunzima ukubangela umonakalo omkhulu kuzo.
Izitena ezirhabaxa ze-alumina ephezulu zineendlela ezahlukeneyo zokusetyenziswa. Kwishishini lesinyithi, zizinto ezibalulekileyo kwiilinki zezitofu zokwenza intsimbi, izitofu zokwenza intsimbi, kunye nezitofu zokufudumeza kwakhona. Zingamelana ngempumelelo nokukhukuliseka kwentsimbi enyibilikisiweyo kunye ne-slag enobushushu obuphezulu, ukuqinisekisa inkqubela egudileyo yenkqubo yokunyibilikisa kunye nokuphucula ubomi benkonzo yezixhobo kunye nokusebenza kakuhle kwemveliso. Kwishishini lezixhobo zokwakha, izitena ezirhabaxa ze-alumina ephezulu zisetyenziswa rhoqo kwizixhobo ezifana nee-kilns ezijikelezayo zesamente kunye nezitofu zokunyibilikisa iglasi. Kwiindawo ezinobushushu obuphezulu, ukukhuhla komoya ngesantya esiphezulu, kunye nokukrala kwezinto, zisenokugcina ukusebenza okuhle, zixhasa ukusebenza okuzinzileyo kwemveliso yezinto zokwakha. Kwishishini leekhemikhali, izitena ezirhabaxa ze-alumina ephezulu zidlala indima ebalulekileyo kwizitofu ezisabelayo ezinobushushu obuphezulu kunye neegesi. Ngokumelana kwazo okugqwesileyo kokubola kweekhemikhali, ziqinisekisa ukhuseleko kunye nokusebenza kakuhle kwenkqubo yemveliso yeekhemikhali.
Sixhotyiswe ngezixhobo zemveliso eziphambili kunye nenkqubo yokulawula umgangatho engqongqo. Yonke ikhonkco, ukusuka ekuthengweni kwezinto eziluhlaza ukuya ekuhanjisweni kwemveliso egqityiweyo, ijongwa ngononophelo. Ngokwamkela iinkqubo zemveliso eziphambili kwihlabathi liphela, siqinisekisa ukuba umgangatho wezitena ezichasene ne-alumina ephezulu uhlangabezana nemigangatho yamazwe ngamazwe. Kwangaxeshanye, sikwabonelela ngenkxaso yobuchwephesha yobungcali kunye neenkonzo ezipheleleyo emva kokuthengisa. Ngokweemfuno ezahlukeneyo zabathengi, sinikezela ngezisombululo ezenzelwe wena ukuqinisekisa ukuba izitena ezichasene ne-alumina ephezulu zisebenza kakuhle kwizicelo ezisebenzayo.
Ukukhetha izitena zethu ezirhabaxa ze-alumina ephezulu kuthetha ukukhetha umgangatho kunye nokuthembeka. Nokuba ufuna ukuthengwa okukhulu okanye izisombululo zezinto ezirhabaxa zobungcali, singahlangabezana neemfuno zakho. Siyabamkela ngokufudumeleyo abathengi abavela kwihlabathi liphela ukuba banxibelelane nathi kwaye basebenzisane ukudala ikamva eliqaqambileyo kwishishini elishushu kakhulu!
