Cov ntaub ntawv refractory tau muab faib ua cov khoom siv refractory stereotyped thiab indeterminate refractory cov ntaub ntawv, castables yog ib qho ntawm cov ntaub ntawv refractory indeterminate. Cov khoom corundum castable, uas feem ntau yog siv los tsim ntau yam cua sov rauv hauv ob sab phlu thiab lwm yam kev sib koom ua ke, kuj tseem siv rau hauv qhov cub smelting.
Cov castables siv ntau hom refractory aggregates los yog cov ntaub ntawv refractory thiab ib los yog ntau hom kev sib txuas tus neeg sawv cev uas muaj cov hmoov sib xyaw.
Raws li cov ntsiab lus porosity muaj zoo refractory castables thiab porosity ntawm tsis tsawg tshaj li 45% ntawm cov tshav kub rwb thaiv tsev hluav taws-resistant txhaj tshuaj ob hom tshuaj ua ke ntawm castables nyob rau hauv chav tsev kub feem ntau los ntawm kev koom tes ntawm hardening neeg sawv cev ua ib tug tshuaj tiv thaiv thiab hardening, thawj hom dej iav, aluminium sulfate, phosphate castables thiab lwm yam.
