Silica cib rau iav melting rauv yog hais txog siliceous refractory khoom siv rau lub tsev kub kub qhov chaw ntawm iav kiln (tsis nyob rau hauv kev sib cuag nrog iav kua). Lub pas dej kiln yog ib qho nyuaj thiab loj masonry ua los ntawm ntau yam ntaub ntawv refractory. Nws cov vaults feem ntau yog siv silica cib, phab ntsa ntawm lub mis, thiab cov cub tawg me me tau siv silica cib. Los yog -alumina cov khoom hloov. Silica bricks kuj tseem siv rau hauv regenerator vaults thiab lattice cib ntawm qee cov iav kilns.
Silica cib rau iav kiln yog cov khoom siv siliceous refractory feem ntau yog siv hauv tridymite rau kev tsim cov kub kub ntawm iav kiln. Silica cib rau iav kiln yuav tsum muaj cov yam ntxwv hauv qab no.
① Lub ntim ruaj khov ntawm qhov kub thiab txias, thiab lub cub tawg lub cev yuav tsis hloov vim qhov kub thiab txias. Vim lub siab softening kub thiab tsawg creep tus nqi ntawm silica cib, iav kiln tuaj yeem ua rau lub cub tawg tsis muaj deformation ntawm 1600 degree, thiab cov qauv ruaj khov.
② Tsis muaj kuab paug rau lub khob kua. Lub ntsiab tivthaiv ntawm silica cib yog SiO2, thiab yog hais tias muaj ib tug thaiv los yog nto melting poob thaum siv, nws yuav tsis cuam tshuam qhov zoo ntawm cov iav kua.
③ Resistant rau tshuaj tua kab mob. Lub silica cib ntawm cov qauv sab saud yog eroded los ntawm cov roj uas muaj R2O nyob rau hauv cov iav batch, thiab ib tug du metamorphic txheej yog tsim nyob rau saum npoo, uas txo tus nqi yaig thiab plays lub luag hauj lwm tiv thaiv.
④ Qhov loj me me. Qhov hnyav ntawm lub cub tawg tuaj yeem raug txo.
