Using a thermodynamic database and FactSage to optimise
ratio around 1.9 aids desulphurisation and is especially important for hydrogen sensitive steels. In this case deoxidation of the slag also improves desulphurisation and increases the slag volume by addition of a synthetic slag of the same basicity. The Steel Authority of India Ltd (SAIL) is the largest state-owned steel making company in India.
