摘要: The corrosion resistance of alumina-magnesia castable to a basic slag was evaluated find the highly-resistive composition for steel processing. Stable solid phases were CA6, alumina and spinel after firing Al2O3–MgO–CaO–SiO2 system. simulated thermodynamically alumina, castables. solubility each oxide component is expected in order MgAl2O4 > CA6 Al2O3 at 1600°C because formation CA2 on suggesting protection from slag. However, disappear 1800°C changes MgAl2O4. Although by also expected, disappears large amount high temperature. decreases with increasing MgO/CaO ratio owing formation. practical immersion test demonstrated against slag, exhibiting importance
