Abstract:Most of the former study for metallurgical molten slags (MS) was on the assumption that MS is newtonian fluid, and show lots of limitation. For the reasons such as the existence of gas-liquid phase points, MS shows a property of non-newtonian fluid. For this reason, the advances in some areas are conducted, including the measurement method, the factors influencing the MS and the viscosity computed models, which is prepared for the further research of the physical-chemical properties of blast furnace slag bearing titania.
