Ukusebenza kwezitofu zoshishino kuxhomekeke kakhulu kwizixhobo zokwakha ezihlala ixesha elide nezimelana nobushushu. Phakathi kwazo zonke iimveliso ezinganyangekiyo,izitena zomlilo ze-alumina ephezuluzithathwa njengenye yezona ndlela zithembekileyo zokwenziwa kwanamhlanje. Zisetyenziswa kakhulu kwi-metallurgy yentsimbi, ukuvelisa isamente, ubunjineli beekhemikhali kunye nokucubungula i-ceramic, izitena ze-alumina eziphezulu ezinganyangekiyo zigcina uzinzo oluhle kakhulu lobushushu kunye namandla oomatshini phantsi kweemeko zobushushu obuphezulu kakhulu. Ngokuphucuka okuqhubekayo kwemigangatho yemveliso yemizi-mveliso, izitena zomlilo ze-alumina eziphezulu ezifanelekileyo ziye zabaluleka ekwandiseni ubomi benkonzo yesithando somlilo kunye nokunciphisa iindleko zokusebenza kwefektri.
Inzuzo ephambili yezitena zomlilo ze-alumina ephezulu ikumxholo wazo ophezulu we-alumina oxide, ukusuka kwi-48% ukuya kwi-80%. Umxholo ophezulu we-alumina uphucula kakhulu ukunganyangeki, okuvumela izitena ukuba zimelane nobushushu obuqhubekayo phakathi kwe-1400℃ kunye ne-1790℃. Xa kuthelekiswa nezitena zomlilo zodongwe eziqhelekileyo, izitena ze-alumina eziphezulu zokunganyangekiyo zibonelela ngokumelana nokugqwala okuphezulu, ukumelana nokukhukuliseka okunamandla kwe-slag kunye nozinzo olubalaseleyo lobushushu. Zimelana nokuqhekeka kunye nokuguquka phantsi kokutshintsha rhoqo kobushushu, zithintela ngempumelelo umonakalo we-furnace kwaye zinciphise ukugcinwa okungacwangciswanga kunye nexesha lokungasebenzi kwemveliso.
Izitena zethu zomlilo ze-alumina eziphezulu ziveliswa ngezinto eziluhlaza ze-bauxite ezicociweyo ngokucoca okushisa okuphezulu kunye nokuhlolwa komgangatho okungqongqo, okuhambelana ngokupheleleyo nemigangatho yamazwe ngamazwe yokuchasana kwemizi-mveliso. Sinikezela uluhlu olupheleleyo lwezitena ezichasayo ezisemgangathweni nezinobukhulu obufanelekileyo kwii-oven ezijikelezayo, ii-oven eziqhumayo, ii-oven ezifudumezayo kunye nezixhobo ezahlukeneyo zobushushu bemizi-mveliso. Ibhetshi nganye yemveliso ivavanywa uxinano, amandla okucinezelwa, ukuchasana kunye nezinye izalathisi eziphambili ukuqinisekisa umgangatho ozinzileyo nothembekileyo kubathengi bemizi-mveliso yehlabathi.
Ukusebenza kakuhle kweendleko zezona zizathu ziphambili zokuba izitena zomlilo ze-alumina eziphezulu zisetyenziswe kakhulu kwihlabathi liphela. Xa kuthelekiswa nezixhobo zokuchasana ezidityanisiweyo eziphezulu, izitena ze-alumina eziphezulu zilungelelanisa ukusebenza okuphezulu kunye namaxabiso akhuphisanayo. Ubomi bazo obude benkonzo buyanciphisa ukuphindaphindeka kwezinto, iindleko zabasebenzi kunye nelahleko yokuvalwa kwemveliso, nto leyo eyenza ukuba zibe sisisombululo esifanelekileyo sokukhusela ubushushu esizinzileyo nesingabizi kakhulu kunye nesisombululo sokuchasana kumashishini amancinci, aphakathi namakhulu.
Njengoko imveliso yemizi-mveliso yehlabathi isiya ekusebenzeni kakuhle kakhulu kunye nokusetyenziswa kwamandla aphantsi, imfuno yemarike yezinto ezisemgangathweni ophezulu iyaqhubeka ikhula. Abavelisi bezitena zomlilo ze-alumina abangochwephesha baqhubeka bephucula iindlela zemveliso ukuphucula ukusebenza kwe-thermal insulation kunye nokuqina kwemveliso. Kubavelisi bemizi-mveliso abafuna izixhobo ze-furniture ezithembekileyo, izitena ze-alumina ezivavanyiweyo kakuhle, ezihambelana ngokupheleleyo nezinokwenziwa ngokwezifiso zihlala ziyindlela engcono yokuphucula ukusebenza kakuhle kwemveliso kunye notyalo-mali oluphantsi lokusebenza ixesha elide.
Izixhobo ezahlukeneyo zesithando somlilo kunye neemeko zokusebenza zifuna umxholo we-alumina olungiselelwe wena, ubukhulu, ukumelana nokucinezelwa kunye neeparamitha zokumelana nobushushu. Ukuba uceba ukuhlaziya isithando somlilo, ukuthengwa kwezinto ezichaseneyo okanye ukutshintshwa kokugcinwa kwezixhobo, zive ukhululekile ukunxibelelana nathi nangaliphi na ixesha. Sixhaswa ziinkqubo zemveliso ezivuthiweyo kunye namaqela obuchwephesha obuchwephesha, singafanisa iimodeli zezitena zomlilo ze-alumina eziphezulu ezifanelekileyo ngokweemeko zakho zokusebenza ezizodwa kunye neeparamitha zesithando somlilo, sinikezela ngezisombululo ezenziwe ngokwezifiso zasimahla, iikowuteshini ezichanekileyo kunye neenkonzo zokuthenga ezikwindawo enye ukunceda iifektri zilawule iindleko kwaye ziphucule uzinzo lokusebenza kwesithando somlilo.
