Calcined Bauxite
Tlhahisoleseding ya Sehlahiswa
Bauxite e nang le calcinedke e 'ngoe ea lisebelisoa tse ka sehloohong tsa aluminium. Rotary kiln calcined bauxite e fumanwa ka ho calcining bauxite ya maemo a hodimo ka mocheso o phahameng (ho tloha ho 850ºC ho ya ho 1600ºC) ka seboping sa rotary. Sena se tlosa mongobo ka tsela eo se eketsa dikahare tsa alumina.
Bauxite ea calcined e batla e arotsoe ka bauxite ea boemo bo khethehileng, bauxite ea sehlopha sa pele, bauxite ea sehlopha sa bobeli, le bauxite ea sehlopha sa boraro ho ea ka litaba tsa litšila tse kang Al2O3, Fe2O3, le SiO2, hammoho le bongata bo bongata ba clinker le ho monya metsi. Bakeng sa ho etsa hore theko ea bareki e be bonolo haholoanyane, feme ea rona e sebelisa litaba tsa Al2o3 tsa bauxite joalo ka leibole ho e arola ka 55, 65, 70, 75, 80, 85, 88 le 90.
Ntle le moo, ka calcination, boima ba 'mele le khanyetso ea refractory le tsona li tla ntlafatsoa ho ea ka likhato tse fapaneng. Mokhahlelo oa bauxite o ka eketseha haholo.
Bauxite ea calcined e ka fetoloa lehlabathe la bauxite le phofo ea bauxite ea boholo bo fapaneng ba likaroloana, tseo ka bobeli li ka sebelisoang ka ho toba e le lehlabathe le refractory. E na le boemo bo phahameng haholo tšimong ea thepa ea refractory.

Kopo
1. Aluminium metallurgy.
2. Precision casting/ Investment casting: Litefiso tsa Bauxite grog li ka etsoa hlobo bakeng sa ho lahlela ka nepo.
3. Refractory:
(1) Refractoriness ea boleng bo phahameng ba bauxite e ka fihla 1780 ° C ka botsitso bo botle ba lik'hemik'hale le ts'ebetso ea mochine.
(2) Aluminium silicate refractory fiber: boleng bo phahameng ba bauxite bo ka qhibiliha ka sebōping sa motlakase sa arc, ho hlahisa aluminium silicate refractory fiber, e ka etsoang ka kobo ea ceramic fiber, poleiti, lesela joalo-joalo.
(3) Ho kopanya magnesia le bauxite grog le li-binders ho tšela ladle ea tšepe e qhibilihisitsoeng bakeng sa lesela le letle ka kakaretso.
4. Ho hlahisa samente ea bauxite.
5. Abrasives grade bauxite.
6. Indasteri ea Ceramics.
7. Indasteri ea k'hemistri bakeng sa mefuta eohle ea motsoako oa aluminium.
