MgO Saturation in Secondary Metallurgical Lime-aluminate and Lime-silicate Slags

MgO Saturation in Secondary Metallurgical Lime-aluminate and Lime-silicate Slags

This paper provides an informative basis on MgO saturation in secondary metallurgical slags by conducting thermo‐chemical calculations in the ternary base system Al2O3‐CaO‐SiO2 at 1600 °C, 1650 °C and 1700 °C using FactSageTM6.0. The results for lime‐aluminate and lime‐silicate slag are displayed in...

Zusammenfassung:This paper provides an informative basis on MgO saturation in secondary metallurgical slags by conducting thermo‐chemical calculations in the ternary base system Al2O3‐CaO‐SiO2 at 1600 °C, 1650 °C and 1700 °C using FactSageTM6.0. The results for lime‐aluminate and lime‐silicate slag are displayed in a straightforward and illustrative manner. In addition, approximate equations describe the temperature dependencies: a temperature rise of 50 °C increases the MgO saturation limit by about 1 wt. %.
