摘要
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 degrees C maintains a high proportion of 82.68% and the melting temperature is below 1200 degrees 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.
