Optimization of Flow Characteristics of Blast Furnace Slag

Abstract

A study of the flow characteristics of blast furnace slag is important to record the softening and melting phenomena in blast furnace which greatly influence the extent and location of the cohesive zone having a direct say on the blast furnace operation, quality of hot metal and the coke consumption. In the present work, a noble technique (heating microscope) is adopted to determine the flow characteristics of blast furnace slags obtained from different blast furnaces. It is seen that the results so obtained agree very closely with the values obtained from adopting conventional methods of determining the same using the slag atlas. It is also seen that the characteristics temperature are altered with the alteration of C/S ratio and also the MgO content of the blast furnace slag.
