This study presents a comparison between the measured and calculated results of the slag-steel equilibrium in the ASEA-SKF ladle furnace. The new software LiMeS available with the Thermo-Calc software package was applied in order to calculate the slag-steel equilibrium after the argon degassing process. The input data used in the calculations were those achieved by instrumental analysis of the slag-steel samples that were taken before starting the argon degassing process. The results were compared with the measured values. The calculated Al, Mn and Si contents in the molten steel, and the amounts of Al2O3 and SiO2 in the slag, were in good agreement with the measurements. The calculated and the measured O, S and Mg contents in the molten steel, and the S, CaO and MgO contents of the slag, were not in good agreement. It was concluded that LiMeS is a useful tool for slag-steel equilibrium calculations.
