Lub hom phiaj tseem ceeb ntawm kev siv cov roj refractory cib ua lub puab sab hauv ntawm lub kiln yog ua kom qhov kiln ua tau zoo dua yam tsis muaj kev ncua ntau lawm vim kev puas tsuaj los ntawm cov kab ua haujlwm siab rau lub sijhawm ua haujlwm. Yog li ntawd, Refractory Cib ntsa refractory cib siv hauv qhov cub yuav tsum ua kom ntev thiab muaj txiaj ntsig. Xaiv lub cib kom zoo ntxiv rau pib. Dab tsi yog cov kev xav tau yooj yim uas refractory cib rau qhov cub yuav tsum tau ntsib: Yuav kom ua tau raws li qhov yuav tsum tau ua haujlwm ntawm kev ua haujlwm siab, Refractory Cib lawv yuav tsum muaj cov khoom ntawm tsis muag lossis yaj ntawm qhov kub txaus. Nws tuaj yeem tiv taus lub nra ntawm qhov kiln thiab kev ntxhov siab nyob rau hauv cov txheej txheem kev ua haujlwm, Refractory Cib thiab yuav tsis poob cov txheej txheem lub zog, Refractory Cib mos mos ua kom deformation thiab vau ntawm qhov kub siab, Refractory Cib feem ntau qhia los ntawm lub load softening kub.
Qhov ntim tau ruaj khov nyob rau qhov kub siab, Refractory Cib thiab lub cub masonry los yog nchuav lub cev yuav tsis vau vim yog nthuav ntau ntawm cov khoom lag luam, lossis tawg vim muaj kev ua ntau dhau heev lawm, Refractory Cib txo kev pab lub neej. Nws feem ntau ntsuas los ntawm linear expansion coefficient thiab reheating shrinkage (lossis nthuav dav). Refractory cib muaj kev cuam tshuam zoo heev los ntawm kev ua haujlwm ntawm lub ncu. Kev hloov pauv ntawm qhov kub thiab tsis sib xws ua kom sov ua rau cov cua sov yooj yim. Yog li no, Refractory Cib nws yuav tsum muaj qee qhov qib ntawm qhov kub tsis kam poob siab. Refractory cib feem ntau raug rau tshuaj lom neeg ntawm kev daws teeb meem ua kua, gaseous lossis cov khoom ua tau zoo thaum siv, Refractory Cib ua rau cov khoom xeb thiab puas. Yog li ntawd, Refractory Cib khoom yuav tsum muaj qee yam tsis kam rau yaig.
Hauv kev siv, lub pob zeb refractory feem ntau yuav muaj kev kub ceev cov nplaim hluav taws thiab pa taws, Refractory Cib tawg thiab ua rau cov kua hlau thiab molten slag, thiab cuam tshuam thiab puas ntawm cov hlau thiab lwm yam khoom siv. Yog li no, Refractory Cib Nws yuav tsum muaj lub zog txaus thiab hnav tsis kam. Qhov zoo ntawm refractory cib nyob ntawm lawv lub zog, Refractory Cib uas yog tus qauv rau kev ntsuas cov khoom. Cov kev xaiv tsim nyog ntawm cov ntoo thim rov qab kuj tseem nyob ntawm lawv lub zog.
