通过对攀钢铁水硫含量及脱硫炼钢系统的原材料消耗进行全面调查（试验数据采用“样本子集”的数据统计方法进行处理），提出了增加脱硫车间的铁水处理量、优化脱硫工艺，转炉采用活性石灰、少渣炼钢工艺等措施，可大幅度降低炼钢成本。
By comprehensively investigating the sulfur content of hot metal in Panzhihua Iron and Steel (Group) Co., Ltd. and the raw material consumption of the desulphurization and steel-making system (the experimental data are processed by the data statistical method of “Sample Subset”), the amount of hot metal treatment in the desulphurization plant is increased, Converter with active lime, slag less steelmaking and other measures can significantly reduce the cost of steelmaking.
