Magnesia bricks muaj ntau dua 90% magnesium oxide cov ntsiab lus thiab txais yuav periclase raws li lub hauv paus ntsiab lus crystalline. Magnesite Bricks tuaj yeem muab faib ua ob pawg ntawm Burnt Magnesia Bricks thiab Chemical Bonded Magnesite Cib. Magnesite bricks muaj kev ua tau zoo ntawm kev ua haujlwm siab tshaj qhov kub thiab txias zog thiab ntim stability. Thiab tuaj yeem ua haujlwm hauv qhov kub ntawm 1750 ℃, Magnesite cib yog cov khoom siv zoo tshaj plaws rau iav rauv daim ntawv thov.
Cov khoom ntawm Magnesia Bricks
- Siab refractorines,
- Alkaline slag kuj,
- Erosion kuj thiab zoo heev los tiv thaiv oxidation,
- High refractoriness nyob rau hauv load,
- High mechanical zog,
- Volume stability ntawm qhov kub thiab txias.
Magnesia Bricks Manufacturing txheej txheem
Magnesia bricks tuaj yeem muab faib ua ob hom: hlawv magnesite cib thiab tshuaj lom neeg magnesite cib. Burnt magnesite bricks yog tsim los ntawm raw khoom ntawm periclase, tom qab raug rho tawm haujlwm nrog 1550 ~ 1600 ℃ kub kub los ntawm crushing, sib tov, melting thiab molding. Cov khoom purity siab muaj tshaj 1750 ℃ kub kub. Unburnt magnesite cib yog tsim los ntawm kev ntxiv cov tshuaj uas tsim nyog los ntawm melting, molding thiab ziab.
Kev faib tawm ntawm Magnesia Bricks
Vim muaj cov tshuaj sib txawv ntawm magnesia bricks, uas tuaj yeem muab faib ua ntau hom, thiab tag nrho cov cib no yog tsim los ntawm sintering. Raws li cov ntaub ntawv sib txawv, magnesia bricks tuaj yeem muab faib ua cov hauv qab no:
Ordinary magnesia cib: sintered magnesite pob zeb.
Direct bond magnesia cib: siab purity sintered magnesite.
Forsterite cib: peridotite
Magnesia calcia cib: sintered magnesite muaj calcium ntau.
Magnesia silica cib: siab silicon sintered magnesite pob zeb.
Magnesia chrome cib: sintered magnesite thiab qee cov chrome ore.
Magnesia alumina cib: sintered magnesite pob zeb thiab Al2O3.
