Hot metal pretreatment for improving desulfurizing efficiency

摘要

The invention and Torpedo Caro chulseon the blast furnace hot metal pre-treatment of hot metal desulfurization process prior to loading the converter relates to a method , and its purpose is to provide a hot metal pretreatment method for improving the desulfurization efficiency by lowering the hot metal desulfurization process before its viscosity charter Sligo Sligo Sligo converter him and at the same time increasing the basicity by putting him his charter Sligo . ; In order to achieve the above objects , the present invention , there is provided a method of pre- treatment with Torpedo Caro chulseon a blast of hot metal , the Torpedo Car of the charter Sligo Sligo him accordingly converter 1.0 ~ 2.0kg per ton of hot metal comprising: input , and in that the desulfurizing agent to molten iron by introducing the pre-treated according to the method of desulfurizing molten iron for improved efficiency comprising the steps of desulfurization in the technical aspect .
