Product Performance:Nws muaj lub zog siab kub ntim ruaj khov, zoo heev thermal poob siab tsis kam, hnav tsis kam, tshuaj corrosion kuj thiab lwm yam ntxwv.
Main siv:Feem ntau yog siv nyob rau hauv kev hloov chaw ntawm cov cement rotary kilns, decomposition furnaces, tertiary cua ducts, thiab lwm yam khoom siv thermal uas yuav tsum tau thermal shock resistance.
Khoom nta:Raws li cov khoom siv tseem ceeb ntawm kev lag luam refractory, siab alumina cib muaj cov yam ntxwv ntawm siab refractoriness, kuj siab load-softening kub (nyob ib ncig ntawm 1500 ° C), thiab zoo erosion kuj. Lawv yog dav siv nyob rau hauv industrial kilns nyob rau hauv ntau yam lag luam. Txawm li cas los xij, vim tias cov ntsiab lus siab ntawm corundum theem ntawm cov zoo tib yam siab alumina cib, corundum theem crystals nyob rau hauv cov khoom sintered yog loj dua, thiab tawg thiab tev tawm yuav tshwm sim thaum ntsib cua txias thiab cua sov. Lub thermal shock stability nyob rau hauv 1100 ° C dej txias txias tsuas yog ncav cuag 2-4 zaug. Nyob rau hauv lub cement ntau lawm system, vim sintering kub txwv thiab kev ua tau zoo yuav tsum tau rau cov ntaub ntawv refractory kom ua raws li cov tawv nqaij kiln, siab alumina cib tsuas yog siv nyob rau hauv lub hloov chaw ntawm lub teb kiln, lub kiln tail thiab lub preheater ntawm lub decomposition rauv. .
Anti-spalling siab alumina cib yog cov txhuas cib siab uas muaj cov khoom tiv thaiv flaking uas ua los ntawm high-aluminium clinker thiab ntxiv nrog ZrO2 lossis lwm yam ntaub ntawv. Lawv tuaj yeem muab faib ua ob pawg, ib qho yog anti-flaking high-alumina cib uas muaj ZrO2, thiab lwm yam yog thawj hom yog anti-flaking siab alumina cib uas tsis muaj ZrO2.
Anti-spalling high-alumina bricks tuaj yeem tiv taus kub kub loads, tsis txhob poob rau hauv ntim thiab muaj kev nthuav dav, tsis txhob nkag los yog vau, muaj qhov kub thiab txias zog thiab kub thermal zog, siab load softening kub, thiab muaj cua sov zoo. Nws tuaj yeem tiv taus qhov cuam tshuam ntawm qhov kub thiab txias hloov pauv lossis cua sov tsis sib xws, thiab yuav tsis tawg lossis tev tawm. Qhov sib txawv ntawm anti-flaking siab alumina cib uas muaj ZrO2 thiab anti-flaking siab alumina cib tsis muaj ZrO2 lies nyob rau hauv lawv txawv anti-flaking mechanisms. ZrO2-muaj anti-flaking siab alumina cib siv zircon cov ntaub ntawv los ua kev siv zoo heev corrosion kuj. ZrO2 tiv thaiv kev yaig ntawm sulfur-chlor-alkali. Nyob rau tib lub sijhawm, ntawm qhov kub thiab txias, SiO2 muaj nyob rau hauv zircon yuav dhau los ua ib qho kev hloov pauv siv lead ua los 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. Nyob rau tib lub sijhawm, nws tiv thaiv spalling thaum kub thiab txias txheej txheem; anti-flaking siab alumina cib uas tsis muaj ZrO2 yog tsim los ntawm kev ntxiv andalusite rau siab alumina cib. Lub andalusite hauv cov khoom yog siv rau theem nrab mulliteization hauv cov cement kiln. Nws tsim cov nyhuv irreversible micro-expansion kom cov khoom yuav tsis ntsws thaum nws txias, offsetting lub shrinkage kev nyuaj siab thiab tiv thaiv structural tev.
Piv nrog rau anti-spalling high-alumina cib uas tsis muaj ZrO2, anti-spalling high-alumina cib uas muaj ZrO2 muaj kev tiv thaiv zoo dua rau kev nkag mus thiab yaig ntawm sulfur, chlorine thiab alkali Cheebtsam, yog li lawv muaj cov khoom tiv thaiv zoo dua. Txawm li cas los xij, vim tias ZrO2 yog cov khoom siv tsis tshua muaj, nws kim heev, yog li tus nqi thiab tus nqi siab dua.Anti-flaking high-alumina cib uas muaj ZrO2 tsuas yog siv nyob rau hauv kev hloov chaw ntawm cov cement rotary kilns. Anti-flaking high-alumina cib uas tsis muaj ZrO2 feem ntau yog siv rau hauv decomposition furnaces ntawm cement ntau lawm kab.
