Dab tsi yog qhov thermal conductivity ntawm firebrick
Lub thermal conductivity ntawm refractory cib muaj kev cuam tshuam zoo rau cov tshuaj muaj pes tsawg leeg, microstructure, ntxhia theem muaj pes tsawg leeg thiab ntom (porosity). Qhov ntau complex cov tshuaj muaj pes tsawg leeg, qhov pom tseeb qhov txo qis ntawm thermal conductivity. Cov khoom siv nrog cov qauv siv lead ua nyuaj muaj cov thermal conductivity tsawg. Lub porosity, zoo li, qhov loj me thiab kev faib tawm ntawm cov cib refractory kuj muaj txiaj ntsig zoo rau cov thermal conductivity.
Cov ntaub ntawv refractory feem ntau muab faib ua ob hom, uas yog, cov khoom siv amorphous refractory thiab cov khoom siv refractory zoo li. Amorphous refractory khoom tseem hu ua castable, yog tsim los ntawm ntau yam aggregates los yog aggregates thiab ib los yog ntau cov nplaum sib xyaw ntawm cov hmoov sib xyaw, yuav tsum tau siv nrog ib lossis ntau cov kua sib tov sib xyaw, muaj zog fluidity. Cov duab refractories feem ntau yog xa mus rau refractory cib, uas nws cov duab muaj cov qauv kev cai, thiab tseem tuaj yeem ua tiav ib ntus thaum txiav raws li xav tau.
