Kev rwb thaiv tsevalumina npuas cibKev Muag Khoom, Cov Neeg Siv Khoom Hauv Australia tau xaj 18 Tons
Alumina hollow pob cib yog dav siv nyob rau hauv kub kub thiab ultra-siab kub furnaces xws li petrochemical industrial gasifiers, carbon dub industrial cov tshuaj tiv thaiv rauv, metallurgical industrial induction furnaces, thiab lwm yam., thiab yog zoo txo qhov hnyav ntawm lub cub tawg lub cev, transforming lub qauv, txuag cov ntaub ntawv, thiab txuag zog. Cov txiaj ntsig pom tseeb tau ua tiav.
Alumina npuas cib yog ua los ntawm high-purity alumina hollow npas raws li lub ntsiab raw khoom thiab sintered ntawm kub. Daim ntawv siv lead ua yog a-Al2O3 microcrystals. Nws muaj qhov zoo ntawm cov tsis tshua muaj ntom ntom, siab compressive zog, tsawg thermal conductivity, thiab siab ua haujlwm kub. Nws tuaj yeem siv dav hauv hauv ob sab phlu ntawm cov kub kub xws li hluavtaws ammonia liquefaction furnaces thiab ethylene gasification furnaces. Nws muaj zog tiv thaiv corrosive gases thiab slag, thiab kev khiav hauj lwm kub yog qis dua 1800 degree.
Cov txheej txheem ntawm kev ua alumina hollow pob cib yog ntxiv alumina raw cov ntaub ntawv rau hauv lub qhov cub hluav taws xob kom yaj mus rau hauv cov kua, thiab tom qab ntawd muab pov tseg rau hauv lub qhov cub ntawm ib lub kaum ntse ntse kom cov kua dej ntws tawm ntawm lub qhov dej ntawm qhov sib xws, yog li ntawd. cov kua ntws los ntawm lub tiaj tus nozzle nrog lub kaum sab xis ntawm 60 degree - 90 degree nrog qhov ntws, thiab tshuab nws mus rau hauv alumina hollow npas nrog a high-speed airflow ntawm lub siab ntawm 0. .
Lub cib no muaj qhov kub thiab txias ua haujlwm zoo thiab thermal rwb thaiv tsev, thiab tuaj yeem siv ncaj qha rau kev ua haujlwm hauv ob sab phlu ntawm kub kub kilns. Nws yuav ua tiav cov txiaj ntsig tseem ceeb hauv kev txo qhov hnyav ntawm lub cub tawg, hloov kho cov qauv, txuag cov ntaub ntawv, thiab txuag lub zog. Tam sim no, cov ntaub ntawv kub kub resistant siv nyob rau hauv lub hauv ob sab phlu yog feem ntau hnyav bricks nrog ib tug ntim ceev ntawm 2. 4.5g / cm³. Rau tib lub cubic meter ntim, kev siv hollow alumina pob cib tuaj yeem txo qhov hnyav los ntawm 1.1-1.9 tons. Txhawm rau ua tiav qhov kev siv kub ib yam, yog siv cov corundum bricks hnyav, tus nqi yog piv rau cov hollow alumina pob cib, thiab cov khoom siv hluav taws xob ntau yuav tsum tau ua. Yog tias hollow alumina pob cib siv, 1.1-1.9 tons ntawm hnyav corundum cib tuaj yeem txuag tau ib lub cubic meter, thiab 80% ntawm cov ntaub ntawv rwb thaiv tsev refractory tuaj yeem txuag tau. Alumina hollow npas muaj qhov pom tseeb thermal rwb thaiv tsev thiab thermal conductivity tsawg. Lawv tuaj yeem ua tiav cov txiaj ntsig zoo thermal rwb thaiv tsev, txo cov cua sov dissipation, thiab txhim kho thermal efficiency, yog li ua tiav lub hom phiaj ntawm kev txuag hluav taws xob. Kev txuag hluav taws xob tuaj yeem ncav cuag ntau dua 30%.
Kev sib piv ntawm alumina npuas cib thiab hnyav cib:
Nyob rau hauv cov nqe lus ntawm qhov hnyav, cov ntaub ntawv kub-resistant siv nyob rau hauv lub hauv ob sab phlu ntawm kilns yog feem ntau hnyav bricks nrog ib tug ntim ceev ntawm 2. 1 3-1.5g/cm. Rau tib lub cubic meter ntim, kev siv alumina hollow pob cib tuaj yeem txo qhov hnyav ntawm lub cev kiln los ntawm 1-2 tons. Los ntawm tus nqi saib, tus nqi ntawm cov cib hnyav thiab hollow pob cib zoo ib yam. Tus nqi ntawm alumina hollow pob cib nyob rau hauv tshwj xeeb tej zaum yuav yog me ntsis siab dua li ntawm hnyav bricks, tab sis nyob rau hauv cov nqe lus ntawm qhov hnyav thiab thermal rwb thaiv tsev kev ua tau zoo, alumina hollow pob cib muaj qhov pom tseeb zoo. Feem ntau siv refractory cib xws li siab alumina cib, silicon carbide cib, av nplaum refractory cib, thiab lwm yam, txawm hais tias lawv cov refractoriness siab tshaj 1700 degree, lawv thermal conductivity siab dhau lawm thiab lawv tsis haum rau siv raws li rwb thaiv tsev txheej. Lawv tsuas yog siv los ua cov txheej txheem refractory. Yog tias koj xav ua kom txuag hluav taws xob hauv qhov cub, koj yuav tsum tau ntxiv ntau txheej ntawm cov ntaub ntawv rwb thaiv tsev xws li lub teeb yuag rwb thaiv tsev cib, aluminium silicate rwb thaiv tsev ntaub plaub, thiab lwm yam. Alumina hollow pob cib tuaj yeem siv ncaj qha los ua cov txheej txheem ua haujlwm, thiab tseem siv tau. raws li rwb thaiv tsev txheej nyob rau hauv qhov kub thiab txias.
