本文探讨了攀钢转炉炼钢工艺的系统优化。从车间生产实际出发,应用系统工程的方法,分析各项生产指标与工艺参数之间的逻辑关系与函数关系,从而建立起多目标系统优化的数学模型。通过数据处理,求出了炼钢中造渣料最小用量的控制参数—造渣系数α,以及各项计算公式。由此达到提高转炉炉龄、提高脱硫效率、降低造渣材料消耗、增加废钢加入量等项目的。两年多的生产实践证明,通过建立在数学优化基础上的科学管理与优化操作,车间生产取得了明显的技术与经济效益。
This article discusses the Panzhihua Iron and Steel converter steelmaking process system optimization. Starting from the actual production in the workshop, applying the method of system engineering, the relationship between logic and function of each production index and process parameters is analyzed, and the mathematical model of multi-objective system optimization is established. Through data processing, the control parameter of the minimum amount of slagging material in steel making - the slagging coefficient α, and the formulas are calculated. So as to improve the furnace furnace age, improve desulfurization efficiency, reduce the consumption of slagging materials, increase the amount of scrap steel and other projects. More than two years of production practice has proved that through the establishment of mathematical optimization based on scientific management and optimization of operations, workshop production has made obvious technical and economic benefits.
