| Abstract: | The technology of separately spraying magnesium powder to desulphurize molten iron that can improve the conditions of the original smelting material in rolling furnaces is introduced, and the desulfurization mechanism is briefly described. The sulfur content of the hot metal after pre-desulfurization with the new devel-oped passivated magnesium powder decreased to lower than 0.010% (mass fraction), and the lowest sulfur con-tent is 0.003%. It meet the requirement of hot metal. |
