摘要：

The sulphide capacities of CaO-Al2O3, CaO-Al2O3-MgO and CaO-Al2O3-SiO2 slags were studied at 1 823 to 1 923 K to estimate the sulphur distribution ratio between secondary steelmaking slag and liquid steel. From the obtained results, it was confirmed that substitution of MgO or SiO2 for CaO at a given N(Al2O3) decreased the sulphide capacities in both systems of CaO-Al2O3-MgO and CaO-Al2O3-SiO2. The evaluated maximum values of sulphur distribution ratio for both slags were higher than 1 000 at 1 873 K on the condition of CaO-saturation if the dissolved aluminium content in steel was assumed to be 0.01 mass%.
