Thaum tib neeg xav txogxim av fused alumina, abrasives thiab sib tsoo log feem ntau yog thawj daim ntawv thov uas tuaj rau hauv siab. Txawm li cas los xij, cov khoom siv no tseem ua lub luag haujlwm tseem ceeb hauv kev lag luam refractory, qhov chaw ua haujlwm ntev, tiv thaiv tshav kub, thiab hnav ua haujlwm yog qhov tseem ceeb. Hauv ntau qhov chaw siab - qhov kub thiab txias, xim av aluminium oxide yog ib qho tseem ceeb aggregate thiab muab tub lim uas pab cov khoom refractory tiv taus cov kev ua haujlwm hnyav.
Brown fused alumina yog tsim los ntawm melting siab -zoo bauxite nyob rau hauv ib tug hluav taws xob arc rauv thaum kub heev. Cov khoom uas tau tshwm sim feem ntau yog tsim los ntawm txhuas oxide thiab muaj cov hardness zoo heev, lub siab melting point, muaj zog mechanical zog, thiab zoo thermal stability. Cov khoom no ua rau xim av aluminium oxide yog cov khoom siv zoo tshaj plaws rau cov ntawv thov refractory uas yuav tsum tau ua kom tsis muaj zog, yaig, thiab thermal shock.
Cov ntawv thov hauv Kev Lag Luam Hlau
Kev lag luam steel yog ib qho ntawm cov neeg siv khoom loj tshaj plaws ntawm cov xim av fused alumina. Nws yog feem ntau siv nyob rau hauv ladles, tundishes, cov ntaub ntawv khiav, swb rooj vag, thiab lwm yam refractory Cheebtsam raug molten hlau thiab slag. Cov kev khiav hauj lwm no ua rau muaj kev ntxhov siab loj heev ntawm cov kab hluav taws xob thiab cov qauv refractory.
By incorporating brown aluminum oxide, manufacturers can improve refractory density, enhance wear resistance, and increase service life. Cov khoom siv pab cov khoom siv refractory tswj lawv txoj kev ncaj ncees txawm tias nyob rau hauv kev raug mob mus rau qhov kub thiab txias slag tawm tsam.
Siv hauv Refractory Castables
Nyob rau hauv refractory castables, xim av fused alumina feem ntau yog siv los ua ob qho tib si ntxhib aggregate thiab hmoov zoo. Cov khoom loj dua muab cov qauv kev txhawb nqa, thaum cov qib finer sau cov voids thiab txhim kho qhov ntom ntom.
Qhov kev sib xyaw ua ke no tso cai rau cov xim av xim av oxide-raws li castables kom xa tau lub zog siab thiab ntev - kev ua tau zoo nyob rau hauv qhov cub hauv ob sab phlu, cov phab ntsa rauv, qhov chaw hlawv, qhov chaw tawm, thiab lwm qhov chaw uas muaj qhov hnyav hnyav.
Cov txiaj ntsig zoo rau Cement thiab Tsis yog -Ferrous Industries
Tshaj li steelmaking, xim av fused alumina yog siv dav hauv cov cement kilns, txias tshuab, thiab tsis yog -ferrous hlau smelting furnaces. Cov ntawv thov no feem ntau cuam tshuam nrog kev puas tsuaj los ntawm cov khoom siv raw, clinker, molten hlau, thiab slag.
Qhov zoo tshaj plaws hardness ntawm xim av aluminium oxide pab cov ntaub ntawv refractory tiv thaiv txhua yam hnav, txo cov kev xav tau ntawm kev saib xyuas thiab txuas ntxiv cov cuab yeej ua haujlwm. Qhov no pab txhawb kev txhim kho kev tsim khoom thiab txo tus nqi kho.
Vim li cas cov neeg tsim khoom xaiv Brown Fused Alumina
Ib qho ntawm qhov zoo tshaj plaws ntawm xim av fused alumina yog nws qhov sib npaug ntawm kev ua tau zoo thiab tus nqi. Txawm hais tias cov ntaub ntawv hwm zoo yuav muab cov purity siab dua lossis cov khoom tshwj xeeb, xim av aluminium oxide muab kev hnav zoo heev, siab refractoriness, thiab kev ua tau zoo ntawm tus nqi sib tw.
Thaum xaiv refractory- qib raw cov ntaub ntawv, cov tuam txhab lag luam yuav tsum ntsuas cov ntsiab lus xws li alumina cov ntsiab lus, qib impurity, particle loj tis, thiab cov khoom sib xws. Ib qho khoom ruaj khov ntawm siab - zoo xim av fused alumina pab ua kom muaj kev ua haujlwm zoo ib yam thiab ua haujlwm ntev dua.
Zuag qhia tag nrho, xim av aluminium oxide yog dav siv nyob rau hauv steel, cement, non-ferrous metallurgy, iav, thiab ceramic industries. Nws lub peev xwm los txhim kho lub zog, kev puas tsuaj, kev yaig tsis kam, thiab ua haujlwm ntev ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv niaj hnub refractory formulations. Raws li kev lag luam furnaces tseem xav tau kev ua haujlwm zoo dua thiab ua haujlwm ntev dua, cov khoom siv ntau yam no tseem yog qhov siv tau thiab tus nqi - kev xaiv zoo rau cov tuam txhab refractory thoob ntiaj teb.
