| Abstract: | On the basis of systematic mass and heat balance calculation mode, combining linear program, taking lowest cost of blast furnace burden as aim and taking meeting the burden, heat and chemical restraint as condition the optimization model of blast furnace burden is established. The data of practical production in Laiwu Steel is optimized in the model. Compared with exiting burden structure, the coke rate optimized structure decreased by 0.59 kg/t and 10 kg/t slag amount and cost reduced 43.5 Yuan/t. Through the analysis of the model, the performance-price ratio of acid burden was sorted scientifically. |
