Thermodynamic database of P2O5-containing oxide system for De-P process in steelmaking

The CaO-FeO-Fe2O3-SiO2-MgO-Al2O3-Na2O-P2O5 oxide system is a basic oxide system for the Basic Oxygen Furnace (BOF) process as well as the hot metal de-phosphorization process. Numerous experimental investigations on this oxide system are being carried out to find out the advanced process route for P removal from molten iron. In spite of their industrial importance, however, the phase equilibria of the oxide systems containing P2O5 have not been well investigated due to the complexity of their chemistry. No systematic thermodynamic modeling of these systems has been conducted to date, either. In order to meet the strong demands of steelmaking and other industries, new systematic thermodynamic modeling of the P2O5 containing oxide systems (CaO-FeO-Fe2O3-SiO2-MgO-Al2O3-Na2O-P2O5) and key phase diagram experiments have been carried out over the past several years. In the present study, the results of the thermodynamic modeling of unary, binary and ternary P2O5 containing systems and the applications of thermodynamic database to the de-P by multi-component slag in BOF process will be presented in comparison with experimental data. All thermodynamic calculations were performed using FactSage thermodynamic software.
