Amakhono aphezulu okuthenga izitini ze-alumina

1. Umbala wokubukeka nokuthambisa kwendawo

Ukubona i- isitini esiphakeme se-alumina, siqala ukubona ukubukeka kwayo, umbala kanye nokuthambisa okungaphezulu. Lapho izinga lezitini eziphakeme ze-alumina lingalungile, ukugcotshwa kwangaphandle kuzoba mpofu, futhi amandla esitini se-alumina ephakeme azoba mpofu.

Bambalwa abantu abakwazi ukuthenga izitini ze-alumina eziphezulu. Ukufana kokubukeka nombala wezitini eziphezulu ze-alumina refractory kubonisa ukuthi izinto zixubene ngokulinganayo ngesikhathi sokukhiqiza. Ukusabalalisa okungalingani kwezinto kuzoholela ekusabalazweni okungalingani kwamandla ezitini eziphakeme ze-alumina. Bese unciphisa amandla onke kanye nempilo yesevisi yesitini esiphezulu se-alumina;

2, ukungcola kwangaphandle

Ngaphezu kwalokho, kuwukubheka okuqukethwe kokungcola ebusweni bezitini eziphakeme ze-alumina. Ezitini eziphakeme ze-alumina, sivame ukubona amachashaza amnyama phezulu. Lokhu ukungcola ezintweni ezingavuthiwe. Ngokwethiyori, ukungcola okumbalwa, kungcono, ngoba kukhona ukungcola okuningi. Kuyi-iron oxide, emane yehliselwe ekubeni insimbi encibilikisiwe egeleza endaweni yokushisa ephezulu kuhhavini, ibangele ukulimala kwesakhiwo sesitini se-alumina ephezulu, bese ithinta impilo yesevisi yesitini se-alumina ephezulu.

Njengomkhiqizo wezimboni, ikhwalithi yezitini eziphezulu ze-alumina ithinta ngokuqondile ukuphepha kokukhiqiza nezindleko zokukhiqiza zebhizinisi. Izitini ezisezingeni eliphansi ze-alumina ngeke nje zibangele iziteleka ezihlukahlukene zokulungisa ekukhiqizeni, zandise izindleko zokukhiqiza, kodwa futhi zibangele ukwakhiwa Ukwenyuka kwezingozi zokuphepha ezingenakulinganiswa ekukhiqizeni.
