Muaj pes tsawg leeg siab alumina cib

Cov ntxhia muaj pes tsawg leeg ntawm siab alumina cib yog corundum, mullite thiab iav theem. Nws cov ntsiab lus nyob ntawm Al2O3 / SiO2 piv thiab hom thiab ntau ntawm impurities. Qib ntawm refractory cib tuaj yeem raug cais raws li cov ntsiab lus ntawm Al2O3. Cov ntaub ntawv raw yog ntuj ore ntawm siab bauxite thiab sillimanite, nrog rau clinker calcined nrog alumina, sintered alumina thiab hluavtaws mullite nyob rau hauv sib txawv proportions. Nws feem ntau yog tsim los ntawm cov txheej txheem sintering. Tab sis cov khoom tseem ceeb yog fused cam khwb cia bricks, granular bricks, unfired cib, thiab tsis-taw refractory cib. High-alumina refractory bricks yog dav siv nyob rau hauv steel, non-ferrous hlau thiab lwm yam lag luam.
