Advances of measurement and calculation model of slag viscosity

As a physical property concerned by metallurgical workers, it is very important for controlling the metallurgical processes that how to obtain the viscosity of different slag systems. The relationship between slag viscosity and chemical composition, structure and temperature were expounded in present work from the points of view of viscosity effect factors. The commonly used test methods and their developments were summarized, and the advantages and disadvantages of them were discussed. Considering that viscosity measurement is a very time-consuming work, the development of viscosity models is of great significance to improve the efficiency of metallurgical processes. The classical viscosity models were classified based on their modeling principles, the applicability and limitations of each model and the future trends in modeling and calculation methods were discussed.
