Abstract
No-cement alumina-magnesia (Al₂O₃-MgO NC) and low-cement alumina-spinel (Al2O3-MgAl2O4 LC) castables are high-performance refractories widely used in the steel industry, where resistance to steel slag corrosion is essential. In this study, spinel-forming NCCs and spinel-containing LCCs were investigated by dynamic corrosion testing in an induction furnace at 1600–1660°C. The effects of magnesia fume, microsilica, and preformed spinel contents were examined. Corrosion mechanism was analyzed using SEM-EDS, XRD, heating microscope thermal analysis, and thermodynamic calculations (FactSage 8.4). NC in-situ spinel-forming castables with 5 wt% MgO addition exhibit significantly higher resistance to basic slag attack compared with LC castables containing 9–22 wt% synthetic spinel, and this resistance is further improved by eliminating microsilica. The resistance results from the formation of dense secondary spinel protective layer, (Mg,Fe,Mn)(Al,Fe,Mn,Cr)₂O₄, along with CaAl₄O₇ and CaAl₁₂O₁₉, facilitated by the formation of a transient CMA-type phase. As a result, the material densifies at the slag interface, improving corrosion resistance.
