To improve the lime–magnesium desulphurisation process at BOS No. 2 at Corus Strip Products IJmuiden, a process model is derived based on the description for the bubble plume generated by injected carrier gas and reaction kinetics of the desulphurisation agents. The model is suited to simulate variations of gas flow and injection rates of CaO and Mg during the process. A parameter study was done in order to improve the operational practice. To validate the model assumptions and to get more knowledge of the reactions of Mg, hot metal samples have been taken before, during and after desulphurisation. SEM analysis revealed (Mg, Mn)S particles with varying Mn content, often combined with Ti(C, N) accumulated in the hot metal. The morphology of the interface between slag and steel has been studied.
