Analysis of the secondary cooling water distribution system based on differential evolution algorithm

[摘要] In the continuous casting, the secondary cooling water distribution system has a decisive effect on the quality of billets. An intelligent optimization strategy, which is different from the traditional mode, is adopted to establish a new water distribution mode. In order to match the water volume of each segment, the objective function is designed by the metallurgical criterion and constraint conditions, and the optimal solution is obtained by differential evolution algorithm. It has been verified that the overshoot is low, the total water volume is reduced, and the quality of billets is significantly improved.
