The effect of Al2O3, CaO/SiO2, and B2O3 on the viscosity of high alumina and medium titania blast furnace slag was analyzed. An increase in CaO/SiO2 ratio from 1.14 to 1.44 resulted in higher slag viscosity and break point temperature. They also increased with increasing Al2O3 content but decreased with adding B2O3 and Al2O3 simultaneously at a fixed CaO/SiO2 ratio of 1.14, which suggested that the effect of B2O3 on viscosity and break point temperature is predominant compared to Al2O3. Apparent activation energies of CaO–SiO2–MgO–Al2O3–TiO2–B2O3 slag were found to be between 74 and 169 kJ/mol.

The effects of B2O3and basicity (CaO/SiO2) on the viscous behavior and structure of medium titanium bearing blast furnace slag (MTBBFS) were investigated. High temperature viscosimeter was applied to measure the viscosities of CaO-SiO2-MgO-TiO2-Al2O3-B2O3slag system and X-ray diffraction (XRD), NBO/T ratio, and structure parameterQwere employed to analyze its network structure. The results showed that the viscosity decreased and break point temperature increased with increasing basicity to 1.20. However B2O3addition gave rise to a decrease in slag viscosity and break point temperature inspite of basicity. The more B2O3content leads to the more pronounced variation, especially for the slag with larger basicity. The conventional NBO/T formula was revised to predict the structure variation of relatively complicated medium Ti bearing slag based on the work of Yanhong Gao and other researchers. The increase of B2O3content in slag made parameterQturn fromQ2toQ1, suggesting that network structure became simpler. It was also noticed that the addition of B2O3could suppress the formation of perovskite.

The single factor variance of viscosity experimental data of blast furnace slag was calculated by Minitab software. The influence of slag basicity and chemical compositions on the slag viscosity was obtained. The results show that there have insignificant effects on the slag viscosity when the slag basicity is over than 1.02, MgO content is less than 11.95% or TiO2 content is less than 12.57%. While the slag basicity can be influenced significantly with the slag basicity less than 1.02, MgO content over than 13.95% and TiO2 content over 13.57%. The Al2O3 content of the slag should be less than 12.75%.

In the current paper, we have determined the desulfurization ability of a CaO–MgO–SiO2–Al2O3 slag system using slag-metal equilibrium technique. The chemical composition of slag samples consists of Al2O3 in the range of 25–30 wt%, CaO/SiO2 ratio (0.8–1.6) and MgO (8–16 wt%). All the experiments are conducted at a temperature of 1773 K. The sulphur content in the slag as well as in metal after desulfurization reaction is analyzed using XRF (X-ray Fluorescence Spectroscopy) for calculating sulphur partition ratio (LS) of the slags. The influence of Al2O3, CaO/SiO2 ratio and MgO content on LS have been studied. It is observed that LS increase with an increase in CaO/SiO2 ratio and MgO content, but it reduces as the Al2O3 content increase in slag. Also, the amount of bridge oxygen ([BO]) represented by (O0) decreases with increase in basicity and MgO content. However, O0 increases with increase in Al2O3. It is witnessed that the experimental values closely fit with the values obtained from corrected optical basicity model.
