Cov khoom siv refractory siv nyob rau hauv cov khib nyiab khib nyiab khib nyiab teb kiln yog calcined nrog complex thiab tsis ruaj tsis khov Cheebtsam.Lub hom phiaj ntawm calcination yog incinerate txaus ntshai pov tseg rau hauv slag thiab txo cov residue qhov kub txo tus nqi kom tsawg tshaj li 5% thaum tsis muaj crust nyob rau hauv lub kiln. , txoj kev xaiv refractory ntawm cov khib nyiab khib nyiab khib nyiab teb kiln yog txawv kiag li daim ntawv ntawm teb kiln.
Rau cov ntaub ntawv refractory siv nyob rau hauv rotary kiln rau kev puas tsuaj pov tseg, cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov khib nyiab pov tseg yog complex vim nws ntau hom, yog li nws tau txiav txim siab tias cov tshuaj muaj pes tsawg leeg ntawm cov khib nyiab pov tseg yog incinerated ntawm 700-1000 kub nyob rau hauv rotary kilns, thiab Cov ntsiab lus tseem ceeb ntawm cov roj tso tawm tom qab calcination ntawm cov khib nyiab pov tseg yog me ntsis acidic.
Nyob rau hauv refractory, refractory castable rau acidic gas muaj kev ruaj ntseg zoo, AL2O3 SiO2 khib nyiab teb kiln yog ib tug zoo corrosion kuj thiab castable refractory, thaum xaiv cov khoom refractory, tsis xaiv cov khoom refractory, Fe2O3 cov ntsiab lus ntau npaum li sai tau vim Fe2O3 FeCL3 reacts nrog. chlorine gas, theem roj, volatile thiab overbalance lub refractory cib, cov cement rotary kiln yog feem ntau siv nyob rau hauv corrosion kuj ntawm ib puag ncig tiv thaiv cov khoom Magnesia hlau spinel cib, nyob rau hauv cov khoom siv phom sij rau cov khib nyiab refractory refractory xaiv yog tsis tsim nyog, nyob rau hauv qhov kev phom sij. khib nyiab rotary kiln pub thiab qhov hluav taws xob castable, kuj yuav tsum tau xaiv cov cement castable tsawg, vim cov cement CaO thiab cov tshuaj chlorine cov tshuaj tiv thaiv, tsim cov kua theem CaC1 yuav txo tau qhov kub thiab txias stability ntawm lub castable.
Hauv kev xaiv cov khoom siv refractory, cov khib nyiab pov tseg yuav tsum siv cov ntaub ntawv refractory nrog zoo hnav tsis kam, thermal shock stability thiab corrosion kuj. Cov txheej txheem tsim khoom ntawm cov khib nyiab pov tseg rotary kiln feem ntau siv cov txheej txheem qis qis qis. Cov roj tseem ceeb cua khib nyiab nkag los ntawm ib qho kev taw qhia thiab qhov ntev ntawm qhov cub yog luv luv (qhov ntev-inch feem ntau tsuas yog 3-5m). Cov tshuaj tiv thaiv hauv qhov cub yog qhov yooj yim, uas yog, cov tshuaj tiv thaiv oxidation combustion. Ntawm cov khoom tseem ceeb tam sim no, mullite sic cib yog ib yam khoom tsim nyog, thiab cov khoom siv castable tuaj yeem xaiv mullite.
