Qhov sib txawv ntawm lub khob cij yuav tsum tau siv ntau hom refractory cib vim lawv ntsib qhov sib txawv ntawm qhov kub thiab txias ib puag ncig. Nov yog qee yam ntawm cov hluav taws kub refractory feem ntau siv hauv iav kilns:
Melting seem: Nyob rau hauv lub molten seem ntawm lub khob rauv, qhov twg kub yog heev, high-alumina refractory cib (feem ntau muaj high-alumina alumina) los yog fused magnesia bricks feem ntau yog siv. Cov cib refractory no muaj qhov kub thiab txias tsis kam thiab corrosion kuj thiab tuaj yeem tiv taus qhov kub kub melting ntawm iav.
Sintered zone: Hauv thaj tsam sintered, aluminium silicate refractory cib feem ntau yog siv vim lawv tuaj yeem tiv taus qhov kub thiab txias dua thiab muaj kev tiv thaiv corrosion zoo dua rau alkali hlau.
Rwb thaiv tsev: Rwb thaiv tsev feem ntau siv lub teeb yuag refractory cib los yog cov ntaub ntawv insulating kom txo tau cov cua sov thiab ua kom muaj zog.
Lub qhov cub thiab qhov hluav taws xob tso tawm: qhov hluav taws xob thiab cov kav dej yuav tsum tau siv cov khoom siv hluav taws xob uas muaj qhov kub thiab txias los tiv thaiv cov pa taws los ntawm eroding lub cib. Aluminosilicate refractory cib feem ntau siv rau hauv cov cheeb tsam no.
Rwb thaiv tsev cib: rwb thaiv tsev cib los yog thermal rwb thaiv tsev cib tuaj yeem siv rau ntawm phab ntsa sab nrauv ntawm lub qhov cub kom txo tau qhov cuam tshuam ntawm qhov kub thiab txias ntawm ib puag ncig.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias hom tiag tiag ntawm refractory cib siv yuav txawv nyob ntawm tus qauv tsim, txheej txheem thiab kev ua haujlwm ntawm iav kiln. Yog li ntawd, thaum xaiv refractory hluav taws cib, nws raug nquahu kom sab laj nrog ib tus kws tshaj lij cov khoom siv hluav taws xob lossis cov chaw tsim khoom siv iav kom paub meej tias cov khoom siv refractory tsim nyog raug xaiv rau daim ntawv thov tshwj xeeb. Tsis tas li ntawd, kev xaiv cov cib refractory yuav tsum xav txog yam xws li tus nqi, durability thiab kev tiv thaiv ib puag ncig.
