Abstract
The viscosity and flow behavior of the industrial heterogeneous highly basic BOF slags with 2 and 8 mass% MgO and 0 to 25 mass% V2O5 were measured by using rotating bob method and hot stage microscope. An increase in the content of V2O5 in slags with 2 mass% MgO led to a slight increase and then a decrease in viscosity. While, in the case of 8 mass% MgO-containing slags, their viscosity decreased with increasing V2O5 content in liquid determined region. Thereby, the behavior of flow point temperature and crystallization temperatures corresponds with the behavior of critical temperature on the viscosity curves for both groups of slags. The NBO/T results revealed a polymerization with the increasing of V2O5 in both slags groups with 2 and 8 mass% of MgO. Moreover, the formation of solid particles at break point in quenched slags were investigated.
