Dinkar, V C (2014) Viscous properties of synthetic high alumina
blast furnace slag.
MTech thesis.



The viscosity of the blast furnace slag, which is greatly influenced by its composition, has to be low at the operating temperature in order to make the slag easy flowing. Such a slag encourages an acceleration of the rate of slag metal reactions/exchanges, thus influencing the efficiency of the blast furnace process. The present project aims at measuring the viscosity of synthetic high alumina Indian blast furnace slags in agreement with the slag compositions encountered in the industries using inner-cylinder-rotating type viscometer (VIS 403). It is observed that the viscosity is greatly influenced by the CaO/SiO2 (C/S) ratio, MgO and TiO2 contents. The measured and the calculated values of viscosity using different models show that the Iida model yields values most close to the measured value. An attempt is made to comment on the structure of the slag based on estimated values of Activation Energy of viscous flow.
