Brown Fused Alumina

Brown Fused Alumina(Al₂O₃Ntau dua lossis sib npaug li 95%) yog ua los ntawm cov khoom zoo siab - zoo bauxite thiab ua kom zoo nyob rau hauv hluav taws xob arc rauv ntawm qhov kub ntawm ntau tshaj 2000 C. Cov khoom siv raw yog lub teeb kub kub alumina bauxite thiab carbon, me ntsis Fe ntxiv. Tom qab raug rho tawm haujlwm hauv hluav taws xob rau qhov kub ntawm 2000 degree, impurities zoo li SiO₂thiab Fe₂O₃raug tshem tawm.

Xim ntawm xim av fused alumina yog xim av, Al₂O₃Cov ntsiab lus feem ntau yog 94.5% -97%, lub ntsiab impurities suav nrog SiO₂, Fe₂O₃, TSI₂, Na₂O , K₂O, MgO thiab lwm yam.

Vim nws cov purity siab, zoo crystallization, muaj zog fluidity, tsis tshua muaj linear expansion coefficient thiab corrosion kuj, thiab tus nqi qis dua piv rau dawb fused corundum thiab tabular corundum, xim av corundum yog dav siv los ua aggregates ntawm corundum castable. Tab sis vim cov nqi hluav taws xob ntau dua thiab siab dua, xim av fused corundum tsis raug nqi -kev ua tau zoo thaum piv rau tabular corundum, yog li feem ntau nws tau siv los ua cov khoom siv abrasive tam sim no.

Muaj particle loj xws li: 0-1mm; 1-3 hli; 3-5 hli; 5-8 hli; Hmoov los yog raws li tus neeg yuav tsum tau muaj.

Brown corundum los yog xim av fused alumina yog tsuas yog siv rau abrasion thiab kub resistant, inoxidizable aggregate thiab filling ntawm zoo li tus thiab monolithic refractory nyob rau hauv steel metallurgy, ntau yam muaj qhov cub, hluav taws xob rauv thiab lwm yam

Cov ntaub ntawv refractory xa mus rau inorganic non{0}}cov ntaub ntawv hlau nrog refractoriness tshaj 1580℃.

Refractory raw khoom yog cov khoom siv raw siv los tsim cov cib refractory thiab monolithic refractories.

Hom: Muaj cov khoom sib xyaw ua ke, cov khoom sib txuas, cov khoom ntxiv, cov tshuaj tiv thaiv -oxidants thiab lwm yam.

Rau cov kev siv sib txawv, muaj cov ntaub ntawv nyoos thiab cov khoom siv hluav taws xob hnyav

Ntev Keter muab cov khoom siv dav dav, suav nrog alumina bauxite siab, Kaolin flint av nplaum, tabular alumina, alumina hmoov, xim av fused alumina, dawb fused alumina, magnesia spinel, mullite thiab lwm yam.
