Thermochemical Calculation of the Quaternary CaO–SiO₂–Al₂O₃–MgO System at 1600°C for Predicting the MgO‐Saturation and MgO–MgO · Al₂O₃ Equilibrium of Secondary Metallurgical Slag

Different quaternary CaO–SiO 2 –Al 2 O 3 –MgO systems were calculated with thermochemical‐calculations at various temperatures by using FactSage6.2. The calculated systems provide enhanced knowledge of secondary metallurgical ladle slag conditions at process temperatures. These systems can also be used for predicting the MgO‐saturation and the MgO–MgO · Al 2 O 3 equilibrium at various temperatures for commonly used ladle slag compositions.
