Experiments were carried out using thermally equilibrating and quenching method on the solubility of CaS in the molten CaO-Al2O3-CaS slags for the fundamental reference to the shape control of inclusions in steel. On the basis of the results, the activity diagram for this ternary system was determined by thermodynamic considerations. The equilibrium relationships were also estimated among the solute elements in molten steel in accordance with the slag compositions.
