Abstract
The study of magnesia-chrome refractories corrosion by liquid steel and the liquid calcium-silicate based slag was carried out in the environment in RH degasser. The microstructures of the as-delivered and tested samples were researched by SEM-EDS methods. Our experiment produced the following results: 1. the initial spinel phase, Mg(Cr,Al,Fe)2O4 solid-solution of magnesia-chrome brick was transformed into Fe and Mn-rich spinel phase (Mg,Mn)(Cr,Fe)2O4 solid-solution, 2. the new phase formed in the corroded brick were (Mn,Mg)O and (Ca,Mg,Mn)SiO4 solid solutions.
