Cov cib av nplaum rwb thaiv tsev yog cov khoom siv rwb thaiv tsev uas ua los ntawm cov av nplaum ua cov khoom siv tseem ceeb. Nws cov ntsiab lus Al2O3 yog 30% -48%.
Cov txheej txheem tsim khoom dav dav ntawmav nplaum rwb thaiv tsev cibyog txoj kev ntxiv hlawv nrog cov hlaws dai ntab, lossis cov txheej txheem ua npuas ncauj.
Cov cib av nplaum rwb thaiv tsev siv dav hauv cov khoom siv thermal thiab cov cub tawg kev lag luam, thiab tuaj yeem siv rau hauv thaj chaw uas tsis muaj kev yaig ntawm cov khoom siv kub siab. Qee qhov chaw uas kov ncaj qha rau cov nplaim taws yog coated nrog refractory txheej kom txo qhov yaig los ntawm slag thiab cov hmoov av roj cua sov, txo kev puas tsuaj. Qhov kub ua haujlwm ntawm cov cib yuav tsum tsis pub tshaj qhov kub sim ntawm kev hloov pauv mus tas li thaum rov ua kom sov. Cov cib av nplaum rwb thaiv tsev yog ib hom khoom siv rwb thaiv tsev sib dua nrog ntau lub qhov hws. Cov khoom siv no muaj porosity ntawm 30% txog 50%.
