Nta:
1. Refractoriness
Lub refractoriness ntawm nws siab tshaj cov av nplaum cib thiab semi-silica cib, ncav cuag 1750 ~ 1790 degree, uas belongs rau cov ntaub ntawv refractory.
2. Load softening kub
Vim tias Al2O3 siab nyob rau hauv cov khoom siv alumina siab, tsawg impurities thiab tsawg fusible iav lub cev, lub softening kub nyob rau hauv load yog siab tshaj li cov av nplaum cib, tab sis vim mullite crystals tsis tsim ib tug network qauv, softening kub nyob rau hauv load yog tseem qis dua. tshaj li ntawm silica bricks.
3. Slag tsis kam
Muaj ntau Al2O3 nyob rau hauv siab alumina cib, uas yog nyob ze rau nruab nrab cov ntaub ntawv refractory, thiab muaj peev xwm tiv taus qhov yaig ntawm acidic slag thiab alkaline slag. ,
Daim ntawv thov:
High alumina cib feem ntau yog siv rau hauv ob sab phlu ntawm lub qhov cub tawg, kub moj tej tawg qhov cub, hluav taws xob rauv lub ru tsev, blast furnaces, reverberatory furnaces thiab teb kilns. Tsis tas li ntawd, lub siab alumina cib kuj tau dav siv los ua qhib hearth regenerative checker cib, plugs rau pouring systems, nozzle bricks, thiab lwm yam. Txawm li cas los xij, tus nqi ntawm high-alumina cib yog siab dua li cov av nplaum cib, yog li nws tsis tsim nyog. siv high-alumina cib qhov twg av nplaum cib tuaj yeem ua tau raws li qhov yuav tsum tau ua.
