Muaj ntau hom castables uas muaj peev xwm muab faib ua cov castables uas tsis hnyav, nyob ntawm seb lawv muaj pes tsawg thiab cov yam ntxwv tshwj xeeb. Qee cov piv txwv feem ntau suav nrog:
1. Cov castables insulatingCov castables no yog tsim los rau lawv cov khoom zoo heev. Lawv muaj qhov ceev tsawg thiab porosity siab, ua tiav los ntawm kev sib xyaw cov khoom sib xyaw ua ke xws li expanded perlite, vermiculite, lossis cov fibers refractory lightweight.
2. Cov castables uas tsis muaj zogCov castables no tau tsim los kom muaj qhov ceev tsawg thaum tseem muab lub zog kho tshuab tsim nyog. Lawv feem ntau muaj cov khoom sib xyaw ua ke zoo li cov cenosphere, cov chamotte sib dua, lossis cov mullite sib dua. Kev sib xyaw ua ke ntawm cov ntaub ntawv sib dua no thiab cov neeg sawv cev sib txuas ua rau cov castables nrog qhov hnyav txo qis.
3. Cov khoom ua npuas ncaujCov khoom ua npuas ncauj yog ua los ntawm kev sib xyaw cov khoom ua npuas ncauj rau hauv cov khoom sib xyaw ua npuas ncauj, uas tsim cov qauv cellular thaum ziab thiab hlawv. Cov qauv cellular no pab txhawb rau qhov ceev qis thiab txhim kho cov khoom rwb thaiv tsev. Cov khoom ua npuas ncauj feem ntau muaj cov khoom sib xyaw ua ke thiab cov neeg ua npuas ncauj.
4. Cov khoom siv vermiculite castablesVermiculite yog ib yam khoom siv ntuj uas nthuav dav thaum raug cua sov. Vermiculite castables muaj cov vermiculite aggregates uas nthuav dav, uas ua rau muaj qhov ceev tsawg thiab cov khoom rwb thaiv tsev zoo. Cov castables no tsim nyog rau kev siv qhov kub nruab nrab.
5. Cov khoom siv alumina npuas: Cov alumina npuas yog cov khoom sib xyaw ua ke uas tsis hnyav, muaj qhov porous uas tsim los ntawm kev ua kom sov ib qib tshwj xeeb ntawm alumina rau qhov kub siab, ua rau muaj cov pa roj npuas hauv cov khoom siv. Cov castables alumina npuas yog cov khoom sib xyaw ua ke uas tsis hnyav thiab muaj cov khoom rwb thaiv tsev zoo, ua rau lawv haum rau kev siv kub siab.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov khoom sib xyaw thiab kev faib tawm ntawm cov castables sib dua tuaj yeem sib txawv ntawm cov chaw tsim khoom thiab tej zaum yuav raug tsim rau cov ntawv thov tshwj xeeb. Yog li ntawd, nws ib txwm pom zoo kom sab laj nrog cov neeg muag khoom refractory lossis cov chaw tsim khoom kom txiav txim siab qhov castable sib dua tsim nyog tshaj plaws rau ib qho project lossis siv rooj plaub tshwj xeeb.
