Application of the generalised central atom model to sulphur containing oxide slags
Through a collaborative research project between CSIRO and ArcelorMittal, the capability of the Generalised Central Atom (GCA) model in describing complex oxide slags has been assessed. A slag model database for the Na2O-K2O-CaO-MgO-MnO-FeOx-Al2O3-P2O5-SiO2 and its sub-systems has been developed. Recently the applicability of the GCA model has been further assessed for sulphur containing oxide slags. The published experimental data on sulphur behaviour in various metallurgical systems has been critically reviewed and analysed. Systematic approach was taken to first model sulphur solubility and sulphide capacity in the binary oxide systems. The sulphide capacity in ternary and high order systems was then predicted by the model using binary parameters. The results of the application of the GCA model to sulphide containing metallurgical slag systems of the CaO-MgO-MnO-Al2O3-SiO2 and its sub-systems will be discussed in the present paper.
