The present study “Characterization and Reuse avenues of BOF Slag as a flux material in sinter” is focused on waste utilization for a sustainable growth and development. In an integrated steel plant, approximately 2-4 tonnes of wastes (including solid, liquid and gas) are generated for every tonne of steel produced. Among all the wastes, slag generated at iron making and steel making units are the key area of concern. With increasing capacities, the mechanism for disposal of large quantities of slag that get generated have gained traction as the environmental issues that it could evoke could become critical for steelmakers. Over the last few years, with better understanding process there is the significant reduction in the volume of slag generated. However, slag generation remains inevitable and emphasis on its recycling remains one of the most serious concerns that need to be solved. Blast furnace granulated slag is a glassy aggregate and used as raw material for pozzolanic cement. But BOF granulated slag is crystalline and less glassy phase compared to BF slag, so 100 % utilization as pozzolanic cement manufacture is limited. Hence, alternate reuse avenues are under study at research or implementation level. The present topic is selected to study the reuse avenues of BOF Slag as a flux material in sinter.
