Hnav-Resistant Refractory CasabFeem ntau yog siv rau qhov kub thiab txias thiab hnav tsis kam, hauv cov chaw kub, thiab muaj cov kev xav tau siab rau cov muaj zog thiab lub zog compressive.
Cov kev ua tau zoo ntawm cov ris-resistant refractory castables yog nyob ntawm cov sib txawv ntawm cov khoom nyoos. Feem ntau, siab-zog refractory aggregates thiab hmoov thiab cov siab-zog binders ntxiv. Rau qee qhov tseem ceeb, vim muaj kev mob hnyav, corundum zirtum, High-alumina Bauxiium Bauxonite Corundum, High-alumina bibide tau ntxiv kom tau raws li kev yuav tsum tau ua.
Feem ntau, cov xwm txheej ntawm kev siv yog qhov twg ntawm cov khoom siv khi tau ntxiv. Tsuav nws yog hnav-resistant, nws yuav tsis tawm ib qho me me sib xyaw ntawm kev ntim nruj. Rau cov ris-resistant casables, cov hnav tsis kam ntawm chav sov feem ntau yuav tsum tsis pub tshaj 10cm3.
Yog tias cov Castable yog siv rau kev ncig ua si lub txaj boilers hauv cov nroj tsuag fais fab, nws yog ib qho tseem ceeb ntawm kev sib cais ntawm cov sib tw dub carmide. Cov phau ntawv yuav ua kom dawb huv calcium aluminate cement nrog silica hmoov.
Yog tias nws tau siv rau hauv ob sab alumina ncua rauv taws cua sov, silicon carrum lossis fuseded dawb corundum lossis fused sorundum lossis fused corundum lossis fused rorundum yuav tsum tau ntxiv nyob rau hauv ib qho kev faib ua feem.
Yog tias nws yog qhov ntxiv rau hauv lub tank tso roj hlau ntawm cov cua sov rauv, sub-dawb corundum thiab xim av corundum yuav tsum tau ntxiv. Cov hmoov yuav tsum yog xwb-melted corundum hmoov. Lub micro hmoov yog zircon micro hmoov.
Rau cov hnav-resistant siv hauv cov roj refining catalytic cracking chav nyob, smelting sinterum lossis patic-puab corundum yuav tsum tau ntxiv nyob rau hauv ib qho kev faib ua feem.
Yog tias siv nyob rau hauv qhov kub tshaj 1500 degree, ua prefabricated blocks tseem yog qhov kev xaiv zoo. Yog tias qee qhov nyiaj ntawm sic yog ntxiv rau cov khoom ua ntej ua rau cov ntu ntawm cov khaub thuas uas prefabricated tsuas yog, tab sis kuj tau zoo dua qhov kub thiab txias zoo.
Hauv ntej, kev siv cov refractory refractory castables yuav tsum ua raws li kev siv kub tiag thiab txawv ntawm cov cua sov kev yaig. Raws li rau cov khoom tsim ntawm cov brickricated bricks los yog Castable Cib, nws kuj nyob ntawm qhov xwm txheej.
