The blast furnace slag was studied using Fact-sage thermodynamic software to simulate the precipitation temperature,species and contents of the minerals precipitated in the cooling process of molten blast furnace slag.The viscosity curves of blast furnace slag during cooling process were obtained by synthetic test instrument for physical characteristics of melt.Mineral compositions and microstructure of the blast furnace slag at different temperatures were analyzed by X-ray diffraction （XRD） and field emission scanning electron microscope （SEM）.The results indicate that the blast furnace slag begins to separate out crystals at 1 350 ℃ and the main crystal phase is composed of gehlenite（Ca2Al2SiO7） and akermanite （Ca2MgSi2O7）.In addition,the suitable temperature range for fibrosis of molten blast furnace slag is 1 350~1 371 ℃.
