Av nplaum rwb thaiv tsev bricks yog refractory rwb thaiv tsev cov ntaub ntawv uas ua los ntawm refractory av nplaum raws li lub ntsiab raw khoom. Nws cov ntsiab lus Al2O3 yog 30% -48%.
Cov txheej txheem ntau lawm ntawmav nplaum rwb thaiv tsev cibyog cov txheej txheem hlawv ntxiv nrog cov hlaws ntab, lossis cov txheej txheem ua npuas dej.
Av nplaum rwb thaiv tsev bricks yog dav siv nyob rau hauv thermal khoom thiab industrial kilns, thiab yuav siv tau nyob rau hauv qhov chaw uas tsis muaj zog yaig ntawm high-temperature molten cov ntaub ntawv. Qee qhov chaw uas tuaj rau hauv kev sib cuag ncaj qha nrog cov nplaim hluav taws yog coated nrog cov txheej txheem refractory kom txo qhov kev yaig los ntawm cov slag thiab cov pa roj av, txo kev puas tsuaj. Kev ua haujlwm kub ntawm lub cib yuav tsum tsis txhob tshaj qhov ntsuas kub ntawm kev hloov pauv mus tas li ntawm kev rov ua kom sov. Av nplaum rwb thaiv tsev cib yog ib yam khoom siv rwb thaiv tsev uas muaj ntau qhov pores. Cov khoom no muaj porosity ntawm 30% mus rau 50%.
