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。
According to the specific conditions of Hangzhou Iron and Steel Plant, the factors influencing the comprehensive energy consumption of ironmaking system and their interrelationships are analyzed from the point of view of system energy conservation, and the optimization model of energy consumption for ironmaking system is established. The model consists of the general model of the ironmaking system and the sintering process submodel, both of which are nonlinear programming models. The model and optimization method were applied to study the optimization of the ingredients of sinter raw materials, the reasonable proportion of sinter ore and pellets and the influence of the production parameters on the comprehensive energy consumption of the iron smelting system.
