Development and Applications of Optimized Coal Blending System for Coal Injection of Blast Furnace
The optimized coal blending system for coal injection is independently developed based on considering the physicochemical characteristics,safety performance and processing property of coal injection aiming at the problems in process of optimizing coal blending for coal injection of blast furnace. The coal blending scheme with cost optimization satis-fied the constraint conditions of production demands is calculated by adopting the hybrid programming technology of VB+EXCELVBA,invoking such algorithms as plan solution and multiple linear regression as well as taking ACCESS as back-ground database. The production applications show that the system model plays an important role in reducing costs and sta-bilizing quality for coal injection of blast furnace.
