High alumina cib yog tsim nrog xaiv bauxite chamotte ua cov khoom siv tseem ceeb, raug rho tawm haujlwm ntawm 1450-1470 ° C los ntawm cov txheej txheem siab heev nrog kev tswj xyuas nruj. High Alumina Hluav Taws Cib yog tsim nrog alumina lossis lwm yam khoom siv raw uas muaj cov ntsiab lus alumina siab dua los ntawm molding thiab firing. vim nws cov khoom nruab nrab refractory alumina refractory tuaj yeem tiv taus acid slag yaig tsis kam.
High Alumina Cib Txheej Txheem
Tau los ntawm Xaiv thiab sieve chamotte rau deironing ua ntej tawg, uas tuaj yeem txhim kho siab alumina bricks zoo. Vim tias muaj kev faib ua feem ntau ntawm grog hauv cov khoom xyaw uas tuaj yeem ncav cuag 90 ~ 95%. Xaiv thiab tshuaj ntsuam deironing ua ntej lub grog crushed.
Peb Qib ntawm High Alumina Brick
Raws li cov ntsiab lus sib txawv Al2O3, High alumina cib tuaj yeem muab faib ua Peb Qib hauv Suav teb.
Qib I High Alumina Bricks muaj ntau dua 75% Al2O3 cov ntsiab lus.
Qib II High Alumina Bricks muaj 60 ~ 75% Al2O3 cov ntsiab lus.
Qib III High Alumina Bricks muaj 48 ~ 60% Al2O3 cov ntsiab lus.
Nta ntawm High Alumina Brick
High alumina cib muaj cov yam ntxwv zoo xws li kev ua haujlwm kub, zoo corrosion thiab hnav tsis kam, siab bulk ntom, cov ntsiab lus hlau tsawg, thiab lwm yam.
