Khoom piav qhia
High alumina silica cib muaj cov txheej txheem ntau lawm. Los ntawm kev ntxiv cov ntaub ntawv sib txawv hauv lub siab alumina cib tuaj yeem tau txais ntau hom kev ua haujlwm siab hluav taws kub, yog tias ntxiv ib qho piv txwv ntawm phosphoric acid thiab sintering ntawm qhov kub thiab txias, phosphate cib tuaj yeem tsim. Los ntawm kev ntxiv ib qho kev faib ua feem ntawm silicon carbide, high-temperature sintering tuaj yeem tsim silicon molybdenum cib los yog silicon carbide cib.
Kev siv cov aluminium bricks siab yog tsuas yog siv rau phab ntsa ironmaking blast furnace, kub moj tej tawg rauv, cua sov rauv saum toj, moj tej tawg rauv, reverberatory rauv, txhua yam hauv ob sab phlu. Tsis tas li ntawd, high-aluminium bricks kuj yog siv nyob rau hauv style furnace heat storage grid bricks, plug heads for pouring management systems.
