Magnesium-Iron-Aluminium Spinel Cib Rau Cement KilnIt yog tsim los ntawm cov siab-purity magnesia, fused magnesia, thiab fused iron-aluminium spinel li cov ntaub ntawv nyoos, thiab cov ntawv sau ua ntej cov hmoov zoo ntxiv, thiab cov ntawv sib xyaw ua ke yog ntxiv. Qhov sib ntxiv ntawm fused hlau-aluminium spinel yog qhov tseem ceeb vim tias thaum lub sijhawm hluav taws kub ua haujlwm ntawm lub pob zeb refractory, Fe ions nyob rau hauv cov hlau-aluminium spinel tuaj yeem tawg mus rau hauv cov matrix ntawm lub cib, ua rau muaj kev daws teeb meem ntawm periclase-iron-alumina spinel. Nyob rau tib lub sijhawm, Mg ion diffusion thiab aluminium ions hauv cov hlau-aluminium spinel tuaj yeem tsim cov magnesium-aluminium spinel, uas yog cov txiaj ntsig zoo los txhim kho qhov ua tau zoo ntawm daim tawv nqaij thiab kev ua haujlwm yooj yooj yim ntawm cov thim rov qab. Lub hom phiaj ntawm kev ntxiv cov txheej txheem ua ntej-ua kom zoo hmoov yog txhawm rau txhim kho cov thermal poob siab ntawm spinel cib. Hauv cov tshuaj ua ntej ua ntej micronized hmoov, ntxiv cov tshuaj ntxiv A ua rau cov khoom lag luam tsim cov kua theem me, uas tuaj yeem txhim kho qhov tawv nqaij qhov kev ua tau zoo ntawm cov khoom; qhov sib ntxiv ntawm cov B ntxiv tuaj yeem txhim kho qhov yooj yooj yim ntawm cov cib thiab lub ncoo cushion txoj kab kev nyuaj siab, thiab txhim kho kev ua haujlwm ntawm lub cib. Yog li no, magnesium-iron-aluminium composite spinel bricks yog heev haum rau tua thaj tsam ntawm kev teb kiln.
Hauv qhov loj-teev cement teb qhov cub ua kom lub chaw tua hluav taws, qhov chaw nkaum yuav tsum muaj kev tiv thaiv los ntawm cov khaub ncaws tsis sib luag thiab ruaj khov kom paub tseeb tias kev khiav haujlwm ntawm lub kaw lus kiln. Hauv magnesia-hlau cib, hlau thiab aluminium oxides yooj yim hnov mob nrog calcium oxide hauv cement clinker los tsim cov nplaim hluav taws xob qis xws li dicalcium ferrite thiab mayenite. Theem theem ntxhia nrog qee yam viscosity tuaj yeem ua rau refractory Cov nplaim ua haujlwm ntawm cov av maj mam tsim cov khaub ncaws tsis sib thooj thiab ruaj khov tawv nrog lub cev tuab txog 200 hli." Kilnskin" tau muaj nyob rau lub sijhawm ntev, uas txo lub siab kub melting poob thiab hnav ntawm refractory cib, thiaj li ua tiav cov txiaj ntsig zoo.
