摘　　要：在保证生铁产量质量的前提下,为了最大限度降低炼铁成本,以烧结原燃料、高炉炼铁原燃料的配料优化为基础,以吨铁成本最低和渣量最低为目标函数,以烧结矿化学成分、碱度、铁水成分、炉渣、炉料结构、焦比、煤比等为约束条件,以VB调用MATLAB多目标规划为优化方法,构建了烧结高炉炉料结构优化模型。该模型统筹炼铁全过程,从整个系统高度科学分析,找到生铁生产成本低、产量高和产品优的烧结炼铁系统炉料优化方案。A design and optimization system about charging ingredients and structure in ironmaking system was established in order to maximize reducing pig iron cost in ironmaking process, at the same time ensure the output and quality of pig iron, according to the metallurgical theory,. Based on the actual production, testing and material balance theory, the system integrated the modules on the VB and MATLAB used multiple objective linear programming. As the result, the optimum burden composition and structure of sinter and blast furnace that satisfied all constraint conditions can be obtained. Standing in the height of the global ironmaking production, the system can design and optimize not only the sintering burden, but also the blast furnace burden. Compared with the traditional production testing and hand calculation in ironmaking system, the project can greatly reduce the production risk and greatly increase the calculation accuracy. Industrial application shows that the system is especially beneficial to reduce the ironmaking cost and at the same time ensure the output and the quality.
