In this work, the softening and dripping experiments under the blast furnace conditions are designed to explore the influences of CaO-/SiO2-/MgO-/Al2O3 on the softening and melting properties of FeO respectively. The results indicate that additions of CaO or Al2O3 decrease the starting softening temperature and no dripping behaviors are found in comparison with the base case results when only FeO is used. On the contrary, the addition of SiO2 or MgO rises the starting and ending softening temperature, at the same time, both the dripping temperature and the maximum pressure drop of the case with the addition of SiO2 are the lowest among all the cases. According to the phase diagram and XRD analysis results, the initial phase with CaO addition in the primary-slags should be C2F (2CaO·Fe2O3) and that with SiO2, MgO, Al2O3 additions are fayalite (2FeO·SiO2), magnesioferrite(MgO·FeO), hercynite (FeO·2Al2O3), respectively.
