Taw qhia
Alumina hollow qhov muag teev cib / Alumina npuas cib yog ua los ntawm alumina hollow pob ua cov khoom siv tseem ceeb, corundum ultrafine hmoov raws li additive, organic khoom raws li binder, tom qab tsim thiab ziab txheej txheem, thiab thaum kawg raug rho tawm haujlwm hauv 1750 ℃ kub kub kiln.Nws belongs rau qeb ntawm lub teeb corundum rwb thaiv tsev cib, cov khoom no muaj ob qho tib si thermal conductivity ntawm rwb thaiv tsev cib, thiab siab compressive zog, Nws yog ib lub teeb thermal rwb thaiv tsev cib uas yuav siv tau ib txwm ntawm 1700 ℃.Alumina hollow pob cib / Alumina npuas cib muaj qhov ua tau zoo ntawm qhov kub thiab txias ua haujlwm, tuaj yeem siv ncaj qha raws li kev ua haujlwm ntawm lub qhov cub kub, kom txo qhov hnyav ntawm lub cub tawg, hloov kho cov qauv, txuag cov ntaub ntawv, txuag lub zog, yuav ua tiav cov txiaj ntsig pom tseeb.
Txheej txheem
Cov txheej txheem ntau lawm ntawm alumina hollow pob yog roughly raws li nram no: Ua ntej ntawm tag nrho cov, cov khoom raw ntawm alumina yog ntxiv rau hauv cov dumping hom arc rauv kom yaj mus rau hauv cov kua, thiab tom qab ntawd lub cub tawg yog dumped ntawm ib lub kaum ntse ntse, kom cov kua molten. ntws tawm ntawm lub tank pouring ntawm ib tug ceev ceev, thiab cov kua ntws los ntawm lub tiaj nozzle ntawm 60 ° ~ 90 nrog lub siab ntawm 0.6 ~ 0.8mpa siab ceev airflow yuav tshuab tawm cov kua ntws, uas yog, alumina hollow pob.Cov pob alumina hollow feem ntau yog muab faib ua tsib qhov ntau thiab tsawg tom qab kuaj xyuas thiab cov khoom tawg tau raug tshem tawm los ntawm kev sib cais ua kua.
Qhov zoo
1. Kub kub: siab softening kub nyob rau hauv load.Reburning hlau hloov tus nqi me me, siv ntev dua.
2. Ua kom zoo rau cov qauv, txo qhov hnyav ntawm lub cub tawg: Tam sim no lub hauv ob sab phlu siv cov ntaub ntawv kub resistant yog hnyav cib, ntim ntom ntawm 2.3-3.0g / cm, thiab alumina hollow pob cib tsuas yog 1.3-1.5g / cm, lub tib lub cubic meter ntim, siv alumina hollow pob cib tuaj yeem txo 1.1-1.9 tons ntawm qhov hnyav.
3. Txuag cov ntaub ntawv: Yuav kom ua tau raws li kev siv kub, xws li kev siv cov khoom hnyav corundum cib nqi thiab alumina hollow pob cib nqi zoo ib yam, tab sis kuj xav tau cov khoom siv rwb thaiv tsev ntau heev.Yog tias siv alumina hollow pob cib, ib lub cubic meter tuaj yeem txuag tau 1.1-1.9 tons ntawm hnyav corundum cib siv, ntau dua tuaj yeem txuag tau 80% ntawm cov khoom siv hluav taws xob.
4. Kev txuag hluav taws xob: Alumina hollow pob muaj cov yam ntxwv thermal rwb thaiv tsev, tsis tshua muaj thermal conductivity, tuaj yeem ua kom zoo thermal rwb thaiv tsev nyhuv, txo cov cua sov emission, txhim kho thermal efficiency, thiaj li txuag zog.Kev txuag hluav taws xob tuaj yeem ncav cuag ntau dua 30%.
