According to the actual requirements in the rolling process, a multi-objective function based on influence function method was built. The objective function was aimed specially at thin gauge strip and solved by Tabu search algorithm. Meanwhile, in order to avoid the strip slipping by the reduction of friction coefficient, the tension schedule was corrected according to the rolling length of work roll. The proposed optimization method has been applied successfully to a 1450mm 5-stand tandem cold mill. Application results show that the optimized rolling schedules are more close to the actual requirements and the flatness quality is improved greatly. https://scientiairanica.sharif.edu/article_3975_d2fafe5dc98357349547fba1e649f018.pdf
