    The viscous behaviors are the important physicochemical properties of slag which can affect the stability and the production cost of the iron-making process. In this study, the effects of MgO/Al2O3 on the viscous behaviors of titanium-bearing slag were investigated by rotating spindle method. The variation of viscosity, the activation energy for viscous flow and break point temperature of slag was analyzed. Besides, in order to connect the viscosity and the slag structure, Fourier transform infrared spectroscopy (FTIR) was performed on as-quenched slags. The results showed that the viscosity of slag was decreased as increasing MgO/Al2O3 content from 0.72 to 1.01. However, the break point temperature was increased, and the activation energy for the viscous flow was initially increased and subsequently decreased. FTIR results revealed that the polymerization degree of complex viscous units in slag decreased with an increase of MgO/Al2O3, which clarify the variation mechanism of viscosity for the different MgO/Al2O3 titanium-bearing slags.
