Kev taw qhia txog kev ua haujlwm thiab kev siv Magnesia alumina cib

Magnesia alumina cib yog tsim los ntawm calcined magnesia (MgO> 90%, CaO <2.2%) nrog cov ntsiab lus calcium tsawg raws li cov ntaub ntawv raw, ntxiv txog 8% muaj alumina hmoov, thiab siv sulfite pulp pov tseg kua ua tus neeg sawv cev. Cov khoom raug rho tawm ntawm qhov kub thiab txias.

Cov ntxhia theem muaj pes tsawg leeg ntawm magnesia alumina bricks yog raws li periclase raws li lub ntsiab siv lead ua thiab magnesia alumina spinel (MgO.Al2O3) raws li matrix. Lub tom kawg hloov lub forsterite nyob rau hauv lub magnesia cib thiab ua tus khi ntawm periclase.

Magnesia-aluminium cib muaj cov khoom zoo tshaj plaws uas tau hais tseg saum toj no, yog li lawv tau siv dav los ua cov ntaub ntawv masonry rau lub ru tsev ntawm cov kub kub smelting furnaces xws li steel-ua qhib-hearth furnaces thiab tooj liab-smelting reverberatory furnaces, thiab tau ua tiav cov cov nyhuv ntawm ncua lub neej ntawm lub cub tawg. Qhov loj qhib hearth tuaj yeem ncav cuag li 300 qhov cub, thiab qhov nruab nrab thiab me me qhib hearth muaj ntau tshaj 1000 furnaces.
