Refractory Calcined Alumina

Hauv qab no yog cov lus qhia ntxaws ntxaws rau daim ntawv thov thiab cov yam ntxwv ntawm alumina hmoov hauv cov ntaub ntawv refractory.

Ib. Kev siv cov calcined alumina hmoov hauv cov ntaub ntawv refractory

1: Hearth bricks, linings thiab refractory thaj ua rau thaj

Calcined alumina hmoov kuj tau siv dav hauv cov ntaub ntawv ceramic, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv refractory. Ceramics ua los ntawm calcined alumina hmoov muaj kev tiv thaiv corrosion zoo thiab kub tsis kam, thiab feem ntau yog siv rau hauv kev tsim cov ntaub ntawv refractory xws li cub cib, rauv hauv ob sab phlu thiab refractory thaj ua rau thaj.

2. Cov khoom siv casting

Calcined alumina hmoov kuj tseem siv rau hauv cov ntaub ntawv casting. Nws tuaj yeem siv los ua cov xuab zeb pwm thiab cov ntawv khi rau cam khwb cia hlau, hlau thiab txhuas alloys, thiab lwm yam, txhawm rau txhim kho qhov zoo thiab txuas ntxiv lub neej kev pabcuam ntawm castings.

3. Cov ntaub ntawv zoo ib puag ncig

Calcined alumina hmoov kuj tuaj yeem siv los ua cov khoom siv ib puag ncig, xws li cov xim hauv ob sab phlu rau cov kav dej tso pa thiab siab - cov tshuaj ntxuav kub. Vim tias nws muaj kuab paug tsawg, tsis yog - tshuaj lom thiab tsis muaj ntxhiab, nws yog thaj chaw tshiab ntawm cov ntaub ntawv zoo ib puag ncig. Nws kuj yog siv dav hauv cov khoom siv hluav taws xob tshem tawm cov plua plav thiab cov ntaub ntawv degradation uas ntes cov pa phem.

Ob: Cov yam ntxwv ntawm calcined alumina hmoov refractory cov ntaub ntawv

1.Qhov kub tsis kam

Lub melting point ntawm calcined alumina hmoov yog siab li 2072 degree, thiab cov ntaub ntawv refractory uas muaj alumina muaj cov ntsiab lus melting siab heev thiab muaj peev xwm tswj tau qhov kev ua tau zoo ntawm qhov kub thiab txias.

2. Corrosion kuj

Calcined alumina hmoov muaj tshuaj lom neeg ruaj khov thiab tuaj yeem tiv taus corrosion los ntawm ntau yam acids, alkalis, ntsev, thiab lwm yam., tshwj xeeb tshaj yog thaum kub kub.

3. High rwb thaiv tsev

Ua los ntawm refined calcined aluminium oxide hmoov, nws muaj cov rwb thaiv tsev siab thiab muaj cov ntawv thov zoo hauv cov khoom siv hluav taws xob.

4. Siab hardness

Calcined alumina hmoov muaj siab hardness, muaj zog tsawg -siab zog thiab zoo hnav tsis kam, yog li nws yog dav siv nyob rau hauv cov ntaub ntawv refractory.

Hauv cov ntsiab lus, calcined alumina hmoov, raws li qib siab - cov khoom ua tau zoo, muaj kev thov dav dav hauv cov khoom siv refractory. Nws zoo siab - kub stability, corrosion kuj, siab rwb thaiv tsev thiab siab hardness ua rau nws indispensable thiab tseem ceeb feem nyob rau hauv lub teb ntawm cov khoom tsim. Peb tau cog lus los muab cov neeg siv khoom nrog cov khoom zoo tshaj plaws refractory, calcined alumina hmoov thiab lwm yam ntaub ntawv refractory. Yog tias tsim nyog, tiv tauj peb hnub no thiab cia peb pab koj nrhiav kev daws teeb meem zoo rau koj cov kev xav tau!
