Feem ntau, cov cua sov siv los ntawm lub cev cub tawg yog li ntawm 22% - 43% ntawm cov roj thiab hluav taws xob siv. Cov ntaub ntawv loj no muaj feem cuam tshuam ncaj qha rau tus nqi ntawm cov khoom tsim tawm. Txhawm rau kom txo cov nqi, tiv thaiv ib puag ncig thiab txuag cov peev txheej, cov cib hluav taws xob rwb thaiv tsev tau dhau los ua cov khoom nyiam hauv kev lag luam cub tawg kub.
Lubcib hluav taws xob rwb thaiv tsevyog cov khoom siv rwb thaiv tsev uas muaj qhov porosity siab, qhov ceev me me thiab cov thermal conductivity tsawg. Lub cib refractory lub teeb muaj cov qauv porous (porosity feem ntau yog 40% - 85%) thiab kev ua haujlwm rwb thaiv tsev thermal siab.
Kev siv cov cib hluav taws kub uas tsis hnyav thiab tsis hnyav ua rau lub cub tawg siv roj ntau, txo lub sijhawm ua kom sov thiab txias ntawm lub cub tawg, thiab txhim kho kev ua haujlwm ntawm lub cub tawg. Vim yog qhov hnyav ntawm cov cib hluav taws kub uas tsis hnyav, lub tsev cub tawg txuag sijhawm thiab txuag zog, thiab qhov hnyav ntawm lub cev cub tawg raug txo qis heev. Txawm li cas los xij, vim yog qhov porosity loj ntawm cov cib hluav taws kub uas tsis hnyav, nws lub koom haum sab hauv yog xoob heev, thiab feem ntau ntawm cov cib hluav taws kub uas tsis hnyav tsis tuaj yeem kov cov hlau yaj thiab nplaim taws ncaj qha.
Cov cib hluav taws kub uas tsis hnyav feem ntau yog siv ua txheej rwb thaiv tsev thiab txheej hauv lub qhov cub. Kev siv cov cib hluav taws kub uas tsis hnyav tau txhim kho qhov ua tau zoo ntawm cov qhov cub kub siab hauv kev lag luam.
