Kev xaiv ntawmRefractor CibRau cov kua qaub huv ob sab phlu yog ncaj qha cuam tshuam nrog Kiln Kev Ua Haujlwm, kev nyab xeeb ntau thiab txij nkawm raug nqi. Nyob rau hauv cov txheej txheem ntawm ib tug txheej txheem ntawm ib nkawm niam txiv hauv kev tshawb fawb, nws yog ib qho tsim nyog los tshawb xyuas cov khoom siv ua ke ntawm cov qauv txheej txheem ntawm lub cev ua ke, cov txheej txheem tsis thiab cov khoom siv. Cov kev ntsuas hauv qab no yog nqa tawm los ntawm peb qhov ntev: Chaw Xaiv Pes Xaiv, Khoom siv kev ua tau zoo thiab kev tswj xyuas cov txheej txheem.
1. Kev xaiv thaj chaw tseem ceeb
Lub txiv qaub lub txiv qaub tuaj yeem muab faib ua plaub ntu loj: thaj chaw hloov chaw, tua thaj tsam thiab thaj chaw txias raws li qhov ntsuas kub. Muaj ntau qhov sib txawv hauv kev ua tau zoo ntawm cov ntaub ntawv ntawm refractory hauv txhua qhov chaw.
Qhov kub nyob rau hauv tshooj preheating yog 1000-} 1050 degree, thiab kev cuam tshuam ntawm cov khoom siv thiab thermal kev ntxhov siab hloov. Nws raug nquahu kom siv cov av nplaum av nplaum refractory lossis high-lub zog dai cov cib, thiab nrum lawv raws li ib tug tag nrho nrogsiv fiber ntau txhawb cov zaub mov
Qhov kev hloov pauv hloov pauv ntawm cov chaw hloov chaw yog 1200 {}}}} B-HM Mullite Bricks yog thawj qhov kev xaiv ntawm thaj chaw no vim tias lawv cov khoom lag luam uas nthuav tawm tsawg dua 50 zaug.
Qhov ntsuas hluav taws kub uas kub siab li 1400 {-}}}}}℃thiab alkaline corrosion tsis xav tau coj mus rau hauv tus account. Magnesium {{3} Richin Rabel Cais Daim Ntawv Qhia Txog Kev Siv Micro-expansion ntawm kev kub siab ntawm 1500℃tawm tsam Cao yaig.
Qhov chaw txias txias yog 1300 - 1400 degree, thiab thermal conductivity thiab thermal rwb thaiv tsev ua tau yuav tsum muaj sib npaug. Lub thermal conductivity ntawm ke-70 siab-alumina refractory breaks mus txog ntawm cov qauv sib xyaw ua ke los tsim kom muaj kev sib xyaw ua ke los ntawm 25% thiab txo cov hluav taws kub ua kom sov.
2. Cov ntsiab lus tseem ceeb ntawm cov khoom ua haujlwm txuam
Cov kev ua tau zoo hauv qab no yuav tsum tau txiav txim siab nyob rau hauv kev xaiv: Refractoriness: Chaw Kho Mob, xws li Magnesium {{1} Aluminium spinel cib. Thermal poob siab: Thaj chaw hloov chaw cov khoom yuav tsum tau ntsib ΔT ntau dua lossis sib npaug nrog 300℃thermal poob siab. Alkali Kuj: Cao yo yaig erosion ntawm cov khoom hlawv cov khoom yuav tsum tsawg dua lossis sib npaug rau 0.5 hli / xyoo. Mechanical zog: chav sov kub compressive zog ntawm cov khoom preheating yuav tsum muaj ntau dua los yog sib npaug rau 80mpa.
3.. Cov ntsiab lus tseem ceeb ntawm kev tswj cov txheej txheem kev tsim kho.
Masonry Txujci: Thaj tsam kub tau txais hluav taws kub ntsuag}}} dawb qhuav masoring thev naus laus zis + steel phaj thauj tog rau hluav taws xob matering converration. Kev nthuav dav sib koom ua ke tsim: 3 {{- 5 hli kev nthuav dav tau teeb tsa rau txhua lub ntsuas ntawm cov ntaub paj rwb, muaj cov paj rwb muaj zog. Kev Soj Ntsuam Zoo: Ib Laser Rareferinder yog siv los tshawb xyuas cov refractory sib koom ua ke yuam kev thiab tswj nws hauv ± 1mm. Los ntawm kev tsim kom muaj peb {{{8} seem} qhov chaw xaiv ntawm lub voj voog Kiln ntawm cov hmoov av ib zaug ntawm cov ntoo tshauv tuaj yeem txo los ntawm 15%.
