Cov Khoom Siv Refractories Rau Cov Khib Nyhiab Phom Sij Hauv Rotary Kiln

Cov khoom siv refractory siv rau hauv cov khib nyiab phom sij incinerator rotary kiln yog calcined nrog cov khoom sib xyaw thiab tsis ruaj khov. Lub hom phiaj ntawm calcination yog incinerate cov khib nyiab phom sij rau hauv slag thiab txo cov seem cua sov txo qis kom tsawg dua 5%. thaum tsis muaj crust hauv lub kiln, txoj kev xaiv refractory ntawm cov khib nyiab phom sij incinerator rotary kiln yog daim ntawv sib txawv kiag li ntawm rotary kiln.

Rau cov ntaub ntawv refractory siv hauv rotary kiln rau kev kho cov khib nyiab phom sij, cov tshuaj lom neeg ntawm cov khib nyiab phom sij yog qhov nyuaj vim nws ntau hom, yog li nws tau txiav txim siab tias cov tshuaj lom neeg ntawm cov khib nyiab phom sij raug hlawv ntawm 700-1000 kub hauv rotary kilns, thiab cov khoom tseem ceeb ntawm cov roj tso tawm tom qab calcination ntawm cov khib nyiab phom sij yog me ntsis acidic.

Hauv cov khoom siv refractory, refractory castable rau acidic roj muaj kev ruaj khov zoo, AL2O3 SiO2 pov tseg rotary kiln yog qhov zoo tiv thaiv corrosion thiab castable refractory, thaum xaiv cov khoom siv refractory, tsis xaiv cov khoom refractory, Fe2O3 cov ntsiab lus ntau li ntau tau vim Fe2O3 FeCL3 reacts nrog chlorine roj, cov roj theem, volatile thiab overbalance lub refractory cib, lub cement rotary kiln feem ntau siv rau hauv kev tiv thaiv corrosion ntawm cov khoom tiv thaiv ib puag ncig Magnesia hlau spinel cib, hauv cov khib nyiab txaus ntshai rotary kiln refractory xaiv cov khoom tsis tsim nyog, hauv cov khib nyiab txaus ntshai rotary kiln pub thiab qhov hluav taws xob castable, kuj yuav tsum tau xaiv qis cement castable, vim tias cov cement CaO thiab chlorine reaction, kev tsim cov kua theem CaC1 yuav txo qhov kub tsis kam thiab kub siab ruaj khov ntawm castable.

Thaum xaiv cov khoom siv refractory, cov khib nyiab phom sij rotary kiln yuav tsum siv cov khoom siv refractory uas muaj kev tiv thaiv zoo, thermal shock stability thiab corrosion resistance. Cov txheej txheem ntau lawm ntawm cov khib nyiab phom sij rotary kiln feem ntau siv cov txheej txheem incineration downstream. Cov roj cua thawj zaug nkag los ntawm ib qho kev taw qhia thiab qhov ntev ntawm lub kiln luv luv (qhov ntev-txoj kab uas hla feem ntau tsuas yog 3-5m). Cov tshuaj tiv thaiv hauv lub kiln yooj yim, uas yog, cov tshuaj tiv thaiv combustion. Ntawm cov khoom lag luam tam sim no, mullite sic cib yog cov khoom tsim nyog dua, thiab cov khoom siv castable tuaj yeem xaiv mullite.
