Litaba

Litene tse phahameng tsa aluminium bakeng sa libopi tse phatlohang li entsoe ka bauxite ea boemo bo phahameng e le thepa e ka sehloohong e tala, e kopantsoeng, e hatelitsoeng, e omisitsoeng le ho chesoa ka mocheso o phahameng.Ke lihlahisoa tse refractory tse sebelisetsoang ho etsa lesela la libono tsa mollo.

2. Litene tse phahameng tsa alumina tse sebelisoang liboping tsa mollo li hokae?

Litene tse phahameng tsa aluminium li hahoa holim'a sebōpi sa sebōpi sa mollo oa sebōpi.Sebōpi sa sebōpi se karolong e ka holimo ea sebōpi sa ho phatloha.Bophara ba eona butle-butle bo atoloha ho tloha holimo ho ea tlase ho ikamahanya le ho atolosoa ha mocheso oa tefiso le ho fokotsa ho ferekana ha lerako la sebōpi ka tefiso.'Mele oa sebōpi o lula seboping sa mollo.50% -60% ea bophahamo bo sebetsang.Sebakeng sena, lesela la sebōpi le hloka ho finyella litlhoko tse joalo, 'me litšoaneleho tsa litene tse phahameng tsa alumina ke ho hanyetsa ho phahameng, mocheso o phahameng o nolofatsang tlas'a mojaro, ho hanyetsa acid, ho hanyetsa alkali, ho hanyetsa ka matla ho khoholeho ea slag, le ho hanyetsa ho apara hantle.E ka khotsofatsoa, kahoo e loketse haholo hore 'mele oa sebōpi sa ho phatloha ho kenngoe ka litene tse phahameng tsa alumina.

Lintlha tse ka holimo ke kenyelletso ea litene tse phahameng tsa alumina bakeng sa libopi tse phatlohang.Tikoloho ea lesela la sebōpi sa ho phatloha ho rarahane 'me ho na le mefuta e mengata ea thepa ea refractory e sebelisoang.Litene tse phahameng tsa alumina ke e 'ngoe ea tsona.Ho na le lintlha tse 3-5 tsa litene tse phahameng tsa alumina tse sebelisitsoeng.Litene tsa Robert tse phahameng tsa alumina li ka sebelisoa lioping tse fapaneng.Haeba ho hlokahala, ka kopo ikopanye le rona.
