Reagents for Desulphurization of Hot Metal – IspatGuru

19/08/2018  19/08/2018  Sodium carbonate can promote separation of hot metal from slag and iron losses in slag are lower. However, presently sodium carbonate alone is no longer being used as desulphurization reagent. This is because it gives a violent gas evolution. The decomposition of the carbonate in contact with the hot metal produces pungent sodium oxide fumes which are harmful to
