The typical inclusions found in the alloy were MnO-SiO2 based, spherically shaped and homogeneously distributed. With isothermal holding at the solid-liquid equilibrium temperature of steel, formation of a secondary SiO2-rich inclusion phase occurred. The changes in the composition of the inclusions depended on the manganese and silicon contents in the metal.
