The simulation model for hot metal dephosphorization process by multi-phase slag was developed by the ISIJ research group of "Process Simulation for Dephosphorization of Pig Iron by Multi-Phases". The model employed a multi-scale model, which was an integration of macro- and meso-scale models. In the macro-scale model, the reactions between the liquid slag and the metal were described by a coupled reaction model. In the meso-scale model, the fraction of solid phase was calculated from the numerated phase diagram data, and the distribution of P2O5 between solid and liquid slag phases was evaluated by thermodynamic data. The dissolution of flux was also considered in the model. The program runs on a normal Windows personal computer (PC) with Microsoft C++ 2010. The pull-down menu is available for selecting jobs. The input and output data files are written in CSV style, which can be handled easily by a spreadsheet processor such as Microsoft Excel. One calculation requires less than a second when a typical PC is used. This program was applied the various experiments carried out by five steelmaking companies in Japan and the reasonable results were obtained. The use of the program is sufficiently easy and enables the user to apply it to processes control as well as process simulation.
