Calcined Bauxite

Calcined bauxite yog ib qho ntawm cov ntsiab lus tseem ceeb ntawm txhuas. Cov khoom siv refractory no muaj hydrous aluminium oxides thiab aluminium hydroxides, tsim los ntawm tom qab ntawm cov pob zeb aluminous nyob rau hauv cov cheeb tsam sov thiab subtropical .Nws tau txais los ntawm calcining (cua sov) qib siab tshaj bauxite ntawm qhov kub siab (ntawm 85OC txog 1600C). cov ntsiab lus alumina. piv rau alumina cov ntsiab lus ntawm li 57% mus rau 58% nyob rau hauv raw bauxite, refractory calcine bauxite muaj cov ntsiab lus alumina ntawm 84% mus rau 90%.

Cov khoom siv tseem ceeb rau Calcined Bauxite yog bauxite ore, feem ntau yog tsim los ntawm txhuas oxides, suav nrog gibbsite, boehmite, thiab diaspore, nrog rau ntau qhov sib txawv ntawm impurities. Cov ore tau dhau los ua cov txheej txheem calcination, feem ntau ntawm qhov kub siab tshaj 1300 degree, hloov nws mus rau hauv bauxiite, tsom rau nws cov ntsiab lus txhuas oxide.

Cov txheej txheem calcination suav nrog cua sov bauxite ore mus rau qhov kub siab hauv cov teb kilns lossis ncej kilns, ua rau tshem tawm cov dej noo thiab hloov pauv ntawm hydrated aluminium oxides rau hauv cov tsis-hydrated, high-alumina qauv yam ntxwv ntawm Calcined Bauxite. Cov thev naus laus zis no ua kom ntseeg tau cov tshuaj lom neeg xav tau thiab cov khoom tseem ceeb rau nws cov kev siv sib txawv.

High Aluminium Oxide Cov ntsiab lus: Calcined Bauxite muaj cov ntsiab lus siab ntawm aluminium oxide (feem ntau siab dua 80%), ua rau nws yog ib qho khoom siv zoo tshaj plaws rau cov ntawv thov refractory xav tau cov ntsiab lus alumina siab.
High Temperature Resistance: Nws cov ntsiab lus alumina siab muab qhov tshwj xeeb ntawm kev tiv thaiv tshav kub, ua rau nws siv nyob rau hauv ntau qhov chaw kub kub yam tsis muaj kev cuam tshuam cov qauv kev ncaj ncees.
Hardness thiab Abrasion Resistance: nws nthuav tawm hardness thiab abrasion tsis kam, ua rau nws haum rau siv nyob rau hauv abrasive daim ntaub ntawv, xws li nyob rau hauv zus tau tej cov abrasives xws li cov xuab zeb thiab sib tsoo log.
Tsawg Thermal Expansion: Nws cov yam ntxwv tsis tshua muaj thermal expansion ua rau nws ruaj khov nyob rau hauv qhov hloov pauv kub.
Cov txheej txheem tsim khoom:
Cov txheej txheem ntau lawm suav nrog kev tsuas thiab kho cov bauxite ore kom tshem tawm cov impurities, tom qab ntawd calcination ntawm qhov kub thiab txias. Cov khoom siv calcined ces crushed, graded, thiab ntim raws li cov kev cai tshwj xeeb rau kev siv sib txawv.
