Kev ua tau zoo ntawm cov khoom:Nws muaj zog ruaj khov kub thiab txias, zoo heev thermal shock tsis kam, hnav tsis kam, tshuaj lom neeg corrosion tsis kam thiab lwm yam ntxwv.
Cov kev siv tseem ceeb:Feem ntau siv rau hauv thaj chaw hloov pauv ntawm cov cement rotary kilns, decomposition furnaces, tertiary air ducts, thiab lwm yam khoom siv thermal uas xav tau thermal shock resistance.
Cov yam ntxwv ntawm cov khoom:Raws li cov khoom siv tseem ceeb ntawm kev lag luam refractory, cov cib alumina siab muaj cov yam ntxwv ntawm kev refractoriness siab, qhov kub thiab txias siab (kwv yees li 1500 ° C), thiab tiv taus kev yaig zoo. Lawv siv dav hauv cov cub tawg hauv ntau yam kev lag luam. Txawm li cas los xij, vim muaj cov ntsiab lus corundum theem siab ntawm cov cib alumina siab ib txwm muaj, cov corundum theem siv lead ua hauv cov khoom sintered loj dua, thiab kev tawg thiab tev tawm yooj yim tshwm sim thaum ntsib cov xwm txheej txias thiab cua sov sai. Kev ruaj khov thermal shock nyob rau hauv 1100 ° C dej txias tsuas yog tuaj yeem ncav cuag 2-4 zaug. Hauv cov txheej txheem tsim cement, vim muaj kev txwv kub sintering thiab kev ua tau zoo rau cov ntaub ntawv refractory kom lo rau ntawm daim tawv nqaij ntawm lub cub tawg, cov cib alumina siab tsuas yog siv tau hauv thaj chaw hloov pauv ntawm lub cub tawg rotary, tus Tsov tus tw ntawm lub cub tawg thiab lub preheater ntawm lub cub tawg decomposition.
Cov cib alumina siab tiv thaiv kev tawg yog cov cib alumina siab uas muaj cov khoom tiv thaiv kev tawg uas tsim los ntawm cov clinker siab txhuas thiab ntxiv nrog ZrO2 lossis lwm yam khoom siv. Lawv tuaj yeem muab faib ua ob pawg, ib qho yog cov cib alumina siab tiv thaiv kev tawg uas muaj ZrO2, thiab lwm qhov yog Hom thawj yog cov cib alumina siab tiv thaiv kev tawg uas tsis muaj ZrO2.
Cov cib uas tiv thaiv kev tawg uas muaj cov khoom siv alumina siab tuaj yeem tiv taus cov cua sov kub siab, tsis ntsws thiab nthuav dav zoo ib yam, tsis nkag lossis tawg, muaj lub zog kub ib txwm thiab lub zog kub kub, qhov kub mos siab, thiab tiv taus cua sov zoo. Nws tuaj yeem tiv taus qhov cuam tshuam ntawm kev hloov pauv kub sai lossis cua sov tsis sib xws, thiab yuav tsis tawg lossis tev tawm. Qhov sib txawv ntawm cov cib uas tiv thaiv kev tawg uas muaj ZrO2 thiab cov cib uas tiv thaiv kev tawg uas tsis muaj ZrO2 yog nyob rau hauv lawv cov txheej txheem tiv thaiv kev tawg sib txawv. Cov cib uas muaj ZrO2 siv cov khoom siv zircon los siv cov khoom siv tiv thaiv xeb zoo heev. ZrO2 tiv taus kev tawg ntawm sulfur-chlor-alkali. Tib lub sijhawm, thaum kub siab, SiO2 uas muaj nyob hauv zircon yuav dhau los ua qhov hloov pauv ntawm cristobalite mus rau quartz theem, ua rau muaj qee qhov ntim nthuav dav, yog li txo qhov kev pheej hmoo ntawm kev tiv thaiv sulfur-chlor-alkali. Tib lub sijhawm, nws tiv thaiv kev tawg thaum lub sijhawm kub thiab txias; Cov cib alumina siab uas tsis muaj ZrO2 uas tiv thaiv kev tawg yog tsim los ntawm kev ntxiv andalusite rau cov cib alumina siab. Cov andalusite hauv cov khoom no yog siv rau kev ua mullite theem ob hauv lub qhov cub cement. Nws tsim cov nyhuv me me uas tsis rov qab tau kom cov khoom yuav tsis ntsws thaum nws txias, them rau qhov kev ntxhov siab ntsws thiab tiv thaiv kev tev tawv.
Piv nrog cov cib uas tiv thaiv kev tawg uas tsis muaj ZrO2, cov cib uas tiv thaiv kev tawg uas muaj ZrO2 muaj kev tiv thaiv zoo dua rau kev nkag mus thiab kev yaig ntawm cov sulfur, chlorine thiab alkali Cheebtsam, yog li lawv muaj cov khoom tiv thaiv kev tawg zoo dua. Txawm li cas los xij, vim ZrO2 yog cov khoom siv tsis tshua muaj, nws kim, yog li tus nqi thiab tus nqi siab dua.Cov cib uas muaj ZrO2 uas tiv thaiv kev tawg thiab muaj zog tsuas yog siv rau hauv thaj chaw hloov pauv ntawm cov qhov cub ua los ntawm cov cement rotary. Cov cib uas muaj ZrO2 uas tiv thaiv kev tawg thiab tsis muaj ZrO2 feem ntau siv rau hauv cov cub tawg ntawm cov kab ntau lawm cement.
