Abstract
In view of iron and steel sintering ingredients, a comprehensive optimization method for iron and steel sintering ingredients is proposed. With the lowest cost of sinter as objective function, through upper and lower limits of chemical composition of neutralization powder and sinter, upper and lower limits of basicity of sinter, and proportion range of raw materials as constraint conditions, a comprehensive optimization model for sintering ingredients is established. Besides, the improved particle swarm optimization is used to solve the comprehensive optimization model. Simulation and calculation is conducted to prove the method effective. The method is used in domestic iron and steel enterprises, compared with actual ingredients ratio, which has strong practicality and is of great significance for reducing cost of sintering production. At the same time, the iron and steel sintering batching system is established, which could make sintering ingredients more visually and significantly and could provide effective technical support for actual sintering plant ingredients.
