A comparative study on environmental impact analysis of synthetic and ESR flux used for refining of steel

as to improve the mechanical property and performance of steel during critical applications. Similarly, Electro Slag Remelting (ESR) fluxes are
used during the remelting of steel ingots in the ESR process for refining purpose. These fluxes have been manufactured by mixing the various
slag components or fusing them at a high temperature. Both of these manufacturing methods have pros and cons during refining of steel. This
investigation focuses on the life cycle assessment of different manufacturing processes of fluxes for steel refining. The major objective of this
investigation is to perform an analysis of environmental impact assessment of the processes. A detailed comparison of the environmental
impact has been carried out and discussed relative to the contribution of different unit steps involved in the manufacturing stage for the cradle to-
gate analysis. The results indicate that energy consumption as well as environmental impact is significant for the mixer and furnace heating
step during production of refining fluxes for the steel industry.
