- Abstract
This study provided a fundamental analysis of the viscous behavior and structure of Ti-bearing blast furnace slags modified by different BO additions with a basicity (CaO/SiO) range of 0.5-0.9. The viscosity of slag melts was measured by rotating cylinder method, and the results showed that both slag viscosity and apparent activation energy for viscous flow remarkably decreased with BO addition. To connect the viscosity variation of slags to the melt structure, Fourier transformation infrared spectroscopy analysis was performed. The results indicated that BO acted as a typical network forming oxide, which was introduced into the network and existed dominantly as a two-dimensional structure, BO triangular. With the increase of BO content, the stretching vibration of BO triangular gradually became more pronounced, which resulted in a simpler and less complex structure and caused the decrease of slag viscosity.
