Abstract：To illustrate the melting mechanism and mineralization mechanism of sintering process. Making clear the influence of MgO and Al2O3 content on sintering liquid phase formation and mineral composition is of vital importance. Liquid phase formation of Fe2O3- SiO2- CaO- Al2O3- MgO system is calculated by Factsage software.As well as the effect of variation MgO and Al2O3 content on liquid phase formation and distribution under different temperatures at oxygen partial pressure of 500Pa. Through the sintering experiment, mineral phase and mineral composition of sinter ore are analyzed. The optimal sintering smelting standard for mass fraction of liquid phase, miner phase and mineral composition is concluded with the software calculation when the content of MgO and Al2O3 is 2.0% and 3.0% in sinter respectively.
