Nyob rau hauv cov cement kilns, refractory bricks feem ntau yog siv los ua cov hauv ob sab phlu kom tiv taus qhov kub thiab txias thiab tshuaj tua kab mob, yog li ua kom muaj kev ruaj ntseg ntev ntawm lub kiln. Thaum xaiv cov refractories bricks haum rau lub cement kiln, ntau yam yuav tsum tau xav txog, nrog rau cov cement kiln cov kev ua haujlwm, qhov kub thiab txias, cua, kev ntxhov siab, thiab lwm yam. Cov kev ua haujlwm sib txawv yuav xav tau ntau hom refractories cib. Cov hauv qab no yog qee yam hom refractory cib uas tuaj yeem xaiv raws li cov kev xav tau tshwj xeeb:
Nyob rau hauv cov nqe lus ntawm cov khoom, refractory hluav taws cib feem ntau yog ua los ntawm cov ntaub ntawv refractory xws li high-alumina alumina, aluminium silicate los yog magnesium silicate. Cov ntaub ntawv no muaj cov yam ntxwv ntawm qhov kub thiab txias.
Los ntawm kev faib cov ntsiab lus ntawm kev pom: Refractory bricks tau muab faib ua cov qib sib txawv, feem ntau yog cais raws li lawv qhov kub thiab txias, corrosion kuj thiab tsis kam mus rau kub thiab txias. Kev faib tawm feem ntau suav nrog siab alumina refractory hluav taws cib, aluminium silicate refractory hluav taws cib, magnesium silicate refractory cib, thiab lwm yam.
Los ntawm cov duab pom: Refractories bricks tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg los hloov mus rau ntau qhov chaw ntawm lub kiln. Cov duab uas muaj xws li squares, semicircles, rings, sectors, etc.
Los ntawm txoj kev xav ntawm kev teeb tsa: Refractory bricks feem ntau yog ntsia siv tshwj xeeb refractory mortar lossis refractory cement. Qhov no pab tswj kom muaj kev sib txuas nruj ntawm cov cib thiab txhim kho qhov hnav tsis kam ntawm cov refractories cib.
Thaum xaiv cov refractories cib haum rau cov cement kiln, ntau yam yuav tsum tau xav txog, nrog rau cov cement kiln cov kev ua haujlwm, qhov kub thiab txias, cua, kev ntxhov siab, thiab lwm yam. Cov kev ua haujlwm sib txawv yuav xav tau ntau hom refractory hluav taws cib. Cov hauv qab no yog qee yam hom refractory cib uas tuaj yeem xaiv raws li cov kev xav tau tshwj xeeb:
High-alumina refractory bricks: Haum rau cov cement kilns nyob rau hauv high-temperature tej yam kev mob vim high-alumina refractory bricks muaj zoo heev kub-resistant. Corrosion resistant, haum rau acidic thiab alkaline ib puag ncig.
Aluminium silicate refractory hluav taws cib: siv nyob rau hauv nruab nrab thiab siab kub tej yam kev mob, haum rau ntau yam cement kiln qhov chaw. Nws muaj zoo hnav tsis kam thiab corrosion kuj.
Aluminium phosphate refractory hluav taws cib: haum rau cov cement kilns nrog kub kub thiab corrosive cua. Nws muaj kev tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog tsim rau ib puag ncig uas muaj cov roj acidic.
Zirconia refractory hluav taws cib: siv nyob rau hauv ultra-siab kub cement kilns thiab muaj kub stability. Resistant rau corrosion thiab haum rau siv nyob rau hauv lub xub ntiag ntawm corrosive tshuaj.
Magnesia-aluminium refractory hluav taws cib: haum rau siv hauv cov cement kiln, qhov chaw uas lawv raug kub thiab txias. Nws muaj kev tiv thaiv zoo rau lub caij txias thiab cua sov.
Silicon carbide refractory cib: haum rau cov cement kilns uas muaj qhov tshwj xeeb, xws li cov tshuaj tiv thaiv kub kub lossis graphite electrode kilns. Nws muaj qhov kub thiab txias tsis kam.
Xaiv qhov tsim nyog refractory bricks yuav tsum xav txog cov kev ua haujlwm tshwj xeeb thiab cov kev cai ntawm cov cement kiln. Feem ntau, siab alumina refractory hluav taws cib thiab aluminium silicate refractory cib yog hom siv ntau tshaj plaws vim lawv muab kev ua tau zoo hauv ntau lub sijhawm. Txawm li cas los xij, nyob rau hauv cov xwm txheej tshwj xeeb, xws li kub siab, corrosive atmospheres, lossis siab kub thiab txias lub voj voog yuav tsum, lwm hom hluav taws kub refractory cib kuj yuav tsim nyog dua.
