针对杭州钢铁厂的具体情况,用系统节能观点分析了影响炼铁系统综合能耗的因素及其相互关系,建立了炼铁系统用能优化模型。模型由炼铁系统总体模型和烧结过程子模型组成,二者均为非线性规划模型。应用所建立的模型和最优化方法研究了烧结原料配料的优化,烧结矿和球团矿的合理配比以及生产参数变化对炼铁系统综合能耗的影响。
Taking a steel works as an example, the factors which influence overall energy consumption of the ironmaking system and their dependences were discussed with view of comprehensive energy conservation, the optimizing model of ironmaking system for energy utilization was developed. The model consists of two parts, the general model of ironmaking system and submodel of sintering process, both are nonlinear program model. The optimum charge mixture in sintering process and optimum ratio of sinter and pellet were researched by the model and optimization method, the influence of the parameters of processes on the overall energy consumption of ironmaking system was also dealt with.
