The one of the crucial property which affects the blast furnace operation is viscosity, which is directly affected by the composition of the slag, viscosity of the slag should be low for the operation purpose at the operating temperature for making an easily free flowing slag. Such a slag boosts reaction rate of slag metal and influence the efficiency of the blast furnace operation. The present project aims at measuring the viscosity of blast furnace slag procured from Adhunik Metallics Limited, Industrial slag which is different from synthetic slag by various means. Both theoretical models and experimental apparatus will be used to predict the viscosity of blast furnace slag at different temperature. The activation energy of different slag will also be estimated from viscosity Vs temperature plots. The effects of chemical composition mainly C/S ratio, MgO content & Al2O3 content will be analyzed in the present study and their effect on the production and energy consumption. In this way an attempt is made to comment on the structure of the slag based on estimated values of Activation Energy of viscous flow and proper conditions and burden material used in the blast furnace to improve the production rate and quality of the product
