  • Desulfurization of steel [SubsTech]

     · Desulfurization of steel by injection of active agents. Sulfur in steel. Sulfur S may dissolve in liquid Fe at any concentration. However solubility of sulfur in solid is limited: 0.002% in α- at room temperature and 0.013% in γ- at 1832°F 1000°C. When a liquid steel cools down and solidifiesthe solubility of sulfur drops and it is liberated from the solution in form of sulfide FeS forming an eutecticwith the surrounding
