Experimental Investigation of the Viscosities of High Titanium Containing Slags with Low Mass Ratio of CaO to SiO₂

Abstract:

This present paper focuses on the viscosities of high titanium containing slags in the process of titanomagnetite smelting by taking the TiO₂-Al₂O₃-CaO-SiO₂ quaternary system as the object. Experimental determinations of the viscosities were carried out in the temperature range from 1573 to 1773K using the rotation cylinder method. The measurements were conducted in the composition range from 23 to 33 mass pct TiO₂, 3 to 9 mass pct Al₂O₃, and 0.3 to 0.7 basicity (mass ratio of CaO to SiO₂). The effects of TiO₂, Al₂O₃, basicity, and temperature on viscosity were studied. The experimental results indicated that the viscosities decreased with increasing TiO₂ content and basicity, and increased with increasing Al₂O₃ content, above the liquidus temperature. Based on the experimental data, the liquidus temperatures of the slags were evaluated using the second derivatives of the activation energies for viscous flow with respect to temperature.
