转炉出钢过程“渣洗”脱硫工艺研究

Study on Process of Desulphurization by Slag lnfiltration in LD Tapping

理论计算和工业试验效果表明 ,在南钢现有生产条件下 ,采用转炉出钢过程“渣洗”脱硫工艺具有比较好的脱硫效果。在进一步优化工艺参数后 ,可以成为有效的脱硫手段 ,降低品种钢在冶炼过程的生产成本。

Theoretical calculation and industrial scale experiments demonstrate that under the present production conditions in Nangan better results of desulphurization can only be achieved by adoption of the process of desulphurization by slag infiltration in LD tapping stage.As an effective measure of desulphurization this process can reduce the production cost of high grade steel by way of further optimization of the process parameters.
