The desulfurization of hot metal using the co-injection of lime and metallic magnesium powders is conventionally practiced after ironmaking to control low sulfur content in the final steels. However, the desulfurization operation using magnesium is rather costly, and cares must be given to its storage and transport due to possible explosion. Sulfide capacities of the Na2O-containing multicomponent slags, recently modeled using the Modified Quasichemical Model in the quadruplet approximation, revealed that the Na2O-based fluxes can be potential alternatives for the traditional desulfurizers. The developed thermodynamic database with optimized parameters is used along with FeLQ database in the FactSage system to compare desulfurization capability of various Na2O-containing fluxes with lime + magnesium mixtures in the hot metal pretreatment.
