1, Khoom piav qhia:
Lub fused cam khwb cia alumina cib yog tsim los ntawm kev siv high-purity alumina raw cov ntaub ntawv, melting thiab casting ntawm kub siab tshaj 2000 degree nyob rau hauv ib tug hluav taws xob arc rauv, fused cam khwb cia - Alumina cib yog ua los ntawm - Al2O3 thiab - Al2O3. Ob lub crystals yog crisscross tsim ib tug heev ntom qauv. Nws yog zoo heev nyob rau hauv muaj zog alkaline tsis kam. Cov khoom muaj yuav luag tsis muaj impurities xws li Fe2O3 thiab TiO2. Lub iav theem yog tsawg heev. Thaum nws nyob rau hauv kev sib cuag nrog cov kua iav, nws tsis tshua muaj cov npuas thiab tsis muaj kuab paug rau lub khob dej kiag li. casting - Alumina cib, nyob rau hauv qhov kub thiab txias hauv qab 1350 degree, muaj zoo tiv thaiv corrosion ntawm molten iav tshaj fused zirconium corundum cib. Yog li ntawd, cov khoom yog tsim nyog rau lub tank phab ntsa, pavement, cov ntaub ntawv txoj kev thiab channel ntawm iav rauv.
Txij li Al2O3 nws tus kheej yog saturated nrog sodium saum toj no 2000 degree, cov khoom yog ruaj khov heev rau alkali chav ntawm kub, thiab tsis hnov mob nrog alkali hlau oxides. Nws thermal shock stability yog qhov zoo tshaj plaws ntawm cov fused cam khwb cia bricks. Txawm li cas los xij, thaum sib cuag nrog SiO2, Na2O nyob rau hauv cov khoom reacts nrog SiO2 los ua loj shrinkage, uas ua rau tawg thiab puas rau lub cib. Yog li ntawd, hluav taws xob melting - Lub alumina cib tsuas yog siv tau rau cov qauv sab saud ntawm lub pas dej ua haujlwm, thiab cov combustion yog buckled rau lub mis phab ntsa thiab cov phab ntsa dai.
Fused cam khwb cia - Alumina cib yog ua los ntawm 90 feem pua ntawm - Al2O3 thiab 4 feem pua -Al2O3, nrog compact qauv thiab zoo heev tshuaj stability. Nws muaj zog corrosion kuj rau ntau yam slag. Nws yog qhov tsim nyog rau qhov cua txias ntawm iav rauv, cov qauv sab saud thiab cov khoom siv hluav taws xob ntawm cov hlau tsis muaj hlau smelting rauv.
