英文摘要	This study provided a fundamental analysis of the viscosity and structure of titanium bearing blast furnace slags modified by different levels of P2O5 addition. The viscosity of slag melts was obtained by rotating cylinder method, which is a significant factor for blast furnace process and utilization of slags. The results showed that the slag viscosity was greatly influenced by basicity. Slag viscosity decreased and the calculated apparent activation energy for viscous flow also decreased with increasing basicity, which indicated the breakdown of melt structure. The addition of P2O5 substantially increased the slag viscosity at each basicity, and the increasing trend was most pronounced at basicity 0.5. To connect the viscosity changes of slags to the slag melt structure, Fourier transformation infrared (FTIR) and Raman spectral spectroscopy analysis were performed in this study. FTIR results clearly indicated that the added P2O5 increased the degree of polymerization of slags, corresponding to the increase of slag viscosity. Based on Raman and FTIR curves, it can be concluded that P2O5 acted as a characteristic network former in the melts.; Metallurgy & Metallurgical Engineering; SCI(E); EI; 1; ARTICLE; zuotaizhang@pku.edu.cn; 7; 1491-1497; 54
