Abstract：The application of three different desulphurization technologies in Shougang and the working principle were introduced. For the three kinds of desulfurization processes, the desulfurization time, desulfurization cycle, desulfurization rate, iron loss, processing temperature drop, converter resulfurization and cost were compared. And the advantages and disadvantages of the three kinds of desulfurization processes were analyzed, the suggestions and opinions of different desulfurization process applied in the different sizes of steel enterprises were given. Taking an example of the initial sulfur mass fraction of 0.035% in iron and the end goal of sulfur mass fraction of 0.003% after the desulfurization, the cost of the single spray particle magnesium desulfurization method and compound injection desulfurization method was increased by 12 and 10 yuan /t, respectively, when compared with that of the KR mechanical stirring desulfurization method. Considering the long- term benefits and safety, KR method was used for the desulfurization in large and medium- sized steel enterprises.
