Cov cib alumina siab yog tsim los ntawm kev xaiv bauxite chamotte ua cov khoom siv raw tseem ceeb, hlawv ntawm 1450-1470 ° C los ntawm cov txheej txheem siab heev nrog kev tswj hwm zoo nruj. Cov cib hluav taws kub Alumina siab yog tsim los ntawm alumina lossis lwm yam khoom siv raw uas muaj cov ntsiab lus alumina siab dua los ntawm kev molding thiab hlawv. vim nws cov khoom siv refractory nruab nrab alumina refractory tuaj yeem tiv taus acid slag erosion tsis kam.
Cov Txheej Txheem Cib Alumina Siab
Tau txais los ntawm Kev Xaiv thiab lim cov chamotte rau kev tshem tawm ua ntej tawg, uas tuaj yeem txhim kho qhov zoo ntawm cov cib alumina siab. Vim tias muaj feem pua ntawm grog hauv cov khoom xyaw uas tuaj yeem ncav cuag 90 ~ 95%. Xaiv thiab tshuaj xyuas deironing ua ntej grog crushed.
Peb Qib ntawm High Alumina Cib
Raws li cov ntsiab lus Al2O3 sib txawv, Cov cib alumina siab tuaj yeem muab faib ua peb qib hauv Suav teb.
Qib I High Alumina Cib muaj ntau dua 75% Al2O3 cov ntsiab lus.
Qib II High Alumina Cib muaj 60 ~ 75% Al2O3 cov ntsiab lus.
Qib III High Alumina Cib muaj 48 ~ 60% Al2O3 cov ntsiab lus.
Cov yam ntxwv ntawm High Alumina Cib
Cov cib alumina siab muaj cov yam ntxwv zoo xws li kev ua haujlwm kub siab, kev tiv thaiv corrosion thiab hnav tsis kam, qhov loj me me, cov ntsiab lus hlau tsawg, thiab lwm yam.

Daim Ntawv Thov Cib Alumina Siab
Cov cib alumina siab siv tau rau hauv lub cub tawg, lub qhov cub kub, lub cub hluav taws xob. Kuj tseem siv cov cib hluav taws kub alumina siab siv rau hauv cov teb ntawm hlau thiab hlau, nonferrous, iav, cement, ceramics, petrochemical, tshuab, boiler, kev lag luam lub teeb, fais fab, thiab kev lag luam tub rog thiab lwm yam.
