摘　　要：基于高炉炼铁过程的物质与能量守恒,采用多目标优化方法,建立了以能耗、成本及CO2排放为目标的高炉生产过程优化数学模型,并将该模型应用到某大型钢铁企业.编制程序得出优化结果,经与实际生产数据比较,验证了模型的正确性.优化结果表明:能耗、成本和CO2排放量均有不同程度降低.同时,利用模型分析了焦比、煤比、烧结矿品位等因素对高炉炼铁生产过程的影响,提出了高炉节能、降耗、减排的方向和措施.Based on the conservation of matter and energy in blast furnace iron-making process and the multi-objective optimization method,a mathematical model was developed with the energy consumption,cost and CO2 emission taken as objectives,and it was applied to the No.1 blast furnace in a certain iron and steel complex.By programming and comparing the optimized results with the real data obtained from production,the model was verified correct.The optimization results showed that all the energy consumption,production cost and CO2 emission decreased to the different degrees.Meanwhile,the effects of such factors as coke ratio,coal ratio and sinter grade on the blast furnace iron-making process were analyzed by the model,and some measures are suggested to take for energy saving,cost decreasing and emission reducing.
