Sulfur is the main harmful element affecting the quality and performance of steel. The sulfur content in molten iron directly determines the processability and applicability of steel. Therefore, desulfurization has become a key step in hot metal pretreatment. This paper analyzed the causes of desulfurization from the perspective of thermodynamics, and pointed out that the suitable conditions for hot metal pretreatment desulfurization are high temperature, low oxygen level and high oxygen anion concentration. Theoretical analysis and performance introduction of the desulfurization mechanism of commonly desulfurizers were carried out, and it is pointed out that the composite desulfurizer couid improve the desulfurization efficiency and reduce the impact on the environment.
