A new mathematical model has been developed to predict the rate of added fluxes, such as lime and dolomite. Furthermore, the dissolution model is part of an overall kinetic model of a top-blown oxygen steelmaking process. The calculations were carried out by coupling existing thermodynamic and kinetic models. A dynamic coupling is suggested to evaluate the saturation level of CaO content in slags using Thermo-Calc. The calculated amount of undissolved lime and slag generated in the process is validated using the industrial data reported in literature and also compared with alternative approaches such as FactSage and Slag Atlas. In addition to CaO saturation levels, the effects of slag composition and temperature, particle size of flux additions, diffusivity of CaO and MgO are included for the calculations of flux dissolution. The aim is to achieve a high degree of accuracy and flexibility in modelling of oxygen steelmaking to optimize flux additions.
