| Abstract: | A experimental desulphurizing treatment was carried out in a 150kg medium frequency induction furnace by injecting lime-based and calcium carbide-based desulphurizers.Research was made on how the changing pattern of the elements in hot metal influence the percentage of hits on desulphurization.Relative kinetic parameters were also calculated,so it was verified that under the condition of <0.04%,it is the mass transfer of sulphur in the hot metal that control the desulphurization reaction speed. |

| Keywords: | pre-desulphuzation of hotmetal mass transfer reaction speed |
