Influence of Fe₂O₃ on Molten Slag Properties in Slag Splashing on Nickel Smelting Converter

Abstract:

To predict the effect of Fe₂O₃ on slag splashing properties in the nickel smelting converter, Factsage software was used to calculate the proportion of the liquid phase and the viscosity for MgO-FeO-Fe₂O₃-SiO₂ melts, the melting temperature was measured using slag column deformation, and the microstructure was also observed. The results show that, when the content of Fe₂O₃ is increased from 13.79% to 24.14%, the liquid phase at 1250°C maintains a high proportion of 82.68% and the melting temperature is below 1200°C; The magnetite and hortonolite with high melting points are considerably increased, and the viscosity rises accordingly. The melting and viscous properties for the slag with high content of Fe₂O₃ were improved by adding MgO. Desired slag splashed layer was formed with the saturated Fe₂O₃ and MgO slag.
