OPTIMIZING MODEL OF ENERGY UTILIZATION FOR IRONMAKING SYSTEM OF A STEEL WORKS

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.
