Abstract：Schedule optimization of tandem cold mill is the important guarantee to achieve the best state of the rolling process. Considering for the influence factors to the cold tandem rolling process, a multi-objective optimized model was founded with equal relative power margin and overcome scratches as object function. The rolling schedule was optimized by adaptive chaotic mutation shuffled frog leaping algorithms. The adaptive chaotic mutation is added to the basic frog leaping algorithm for better accuracy and convergence speed optimization. The practice on 1370mm tandem cold rolling mill in a factory proved that the optimized rolling schedule do better in realizing balance of every stand power，and reducing the probability and extent of the scratch, greatly improved product quality and increased economic efficiency.
