| Abstract: | Adopting thermodynamic calculation method, the influence of raw material with different compositions on blast furnace slag was analyzed, and the impact of the variable MgO content on the slag properties was explored. With CaO-SiO2-Al2O3-MgO-FeO taken for study, the influence of MgO in the blast furnace slag on liquidus temperature and viscosity of the slag was theoretically analyzed by using thermodynamic software FactSage. Finally, a proper content of MgO for blast furnace slag with variable compositions has been determined. |
