Mathematical Model for Blast Furnace Burden Optimization Based on the High-temperature Reactivity

Abstract

On the basis of BF iron-making technical calculation, considering expert knowledge about mutual reactivity of the iron bearing materials at high temperature, the optimization model of blast furnace (BF for short) burden was built according to the linear programming theory and applied to the BF production. The results indicate that the model is reasonable, with the burden structure calculated according to the burden optimization model, the burden cost can be reduced, the metallurgical properties of burden can be improved, and the economic and technical indexes can be increased.
