Kev Loj Siab Loj Hlav Recractory Cibyog cov khoom siv hloov tshiab ua ke uas ua ke lub zog siab, tsis tshua muaj ntom ntom thiab kev ua tau zoo. Nws yog dav siv nyob rau hauv muaj kev muaj rurnaces uas yuav tsum tau ua kom tau raws li cov cai ntawm load-bearing thiab kub ua rau tib lub sijhawm.
Cov yam ntxwv tseem ceeb ntawm High-zog Hnav Hnav Refractory Cib yog raws li hauv qab no:
Lub zog siab: Qhov no yog ib qho ntawm nws cov cim muaj txiaj ntsig tshaj plaws. Piv nrog tsoos tsho rwb thaiv tsev cib (xws li diaomite bricks, nws tau muaj zog ntau chav kub compressive zog thiab kub kub qauv zog. Qhov no tso cai rau nws siv tsis tsuas yog ua ib qho kev ua haujlwm hauv hnab, tab sis kuj yog ib feem ntawm cov qauv ua haujlwm, raug rau qee yam kev ntxhov siab thiab cua sov.
Low bulk density/lightweight: Its bulk density is usually between 0.8 g/cm³ and 1.5 g/cm³ (depending on the material and grade), which is much lower than dense refractory bricks (>2. {0 g \/ cm³). Qhov no zoo heev txo qhov hnyav ntawm lub zog cua sov, txo lub hauv paus thauj khoom, thiab nqa tau cov thermal zoo rwb thaiv tsev kev ua haujlwm.
Kev ncua npe tsis ua haujlwm: nyob ntawm cov khoom (xws li High alumina, Mullite, thiab 1800 degree lossis siab dua, uas tuaj yeem ua tau raws li cov kev xav tau ntawm cov kev siv hluav taws xob siab.
Zoo thermal rwb thaiv tsev kev ua tau zoo: tsawg bulk density txhais tau tias cov khoom siv muaj cua sov, txhim kho cov cua sov kev ua kom sov, txhim kho cov cua sov kev ua haujlwm, txhim kho cov cua sov kev ua haujlwm, thiab txuag lub zog.
Tsawg dua thermal muaj peev xwm: lub teeb ci txhais tau tias tsawg cua sov yuav tsum tau rau cua sov, cov cua sov kom nrawm nrawm, uas txhim kho cov lus teb ceev ntawm cov khoom thiab kev tsim khoom.
Qee lub thermal poob ncua: txawm hais tias feem ntau tsis zoo li ntom nti ua kom kub thiab microstructure (xws li tswj cov Crystal theem).
Tsawg rov qab txoj kab hloov pauv: zoo seem ruaj khov nyob rau hauv cov kub thiab ntev siv, tsis yooj yim rau kev ntsws lossis nthuav dav thiab deform.
