AbstractThe local corrosion of magnesia-chrome refractories containing MgO-Al2O3 spinel has been investigated near the slag-metal interface by immersion tests. The local corrosion extent near the slag-metal interface was found to decrease with the increase of FeO, MgO, and Al2O3 contents in the slag. The local corrosion depths in the diagonal direction on the cross sections of the square prism specimens were always root2 times those in the normal direction of the lateral faces, and the cross sections maintained their initial square shape during whole the corrosion duration. The local corrosion is reckoned to be driven by the Marangori convection, which accelerated the mass transfer of the components dissolved from the refractories.
