Synthetic Slag Compositions For Steel Making And Methods Thereof

Abstract: ABSTRACT “Synthetic Slag Compositions for Steel Making and Methods thereof” The present disclosure provides a synthetic slag composition for steel making. The synthetic slag composition of the present disclosure comprises about 40-80 wt% silica (SiO2) and about 3-20 wt% alkali metal ions. In some embodiments, the synthetic slag composition also 5 comprises alumina, chlorides, CaO, MgO, and Fe2O3. The present disclosure also provides a process for steel making comprising heating a raw material charge to obtain molten charge and adding the synthetic slag composition to the molten charge to obtain a composite slag and molten metal. The composite slag allows easy removal of the slag from the molten metal which in turn results in lower metal loss and lower non-metallic inclusions. The synthetic slag 10 composition of the present disclosure also helps in maintaining the life of the refractory lining of the furnace for a longer duration.
