Summary:Enhancement in steel cleanliness is essential for high-performance steels for their high-end applications in structural, automotive, defence and strategic sectors. The non-metallic inclusions play a decisive role in clean steelmaking. The inclusions have to be necessarily minimized or modified by controlling their morphology, composition and size distribution to reduce the detrimental effect of inclusion on the mechanical properties of steel. The present article discusses the results of a thermodynamic study carried out on the various synthetic slags for inclusion removal. It involves computational thermodynamics determining the products of deoxidation, their physical properties and their implication on the quality of steel.
