MgO solubility in CaO-Fe(t)O-SiO2 slag equilibrated with atmospheric air

摘要

The MgO solubility of the steelmaking slag systemat 1873K was measured under condition of the atmospheric air.The effect of slag composition on the MgO solubility wasdiscussed and quantified. The basicity and the MnO contentdecrease the MgO solubility. However, The effect of iron oxidecontent is observed to be dependant on the basicity of slag. As theiron oxide content increases, the MgO solubility increases for thebasic slag (baasicity≥1.5) but decreases for acidic slag. Thecontent of Al203 shows little effect on the MgO solubility.
