| Abstract: | A thermo-mechanical coupling mathematical model of hot rolling process for aluminum strip was established. On the basis of SRINIVAS adaptive genetic algorithm and considering the impact of the evolution algebra, it made adaptive improvement in the crossover and mutation probabilities, built reasonable nonlinear constrained penalty functions and took the power, load distribution and shape as optimization targets to optimize the hot finishing rolling schedule for aluminum strip. Effectiveness of the algorithm was validated through a comparison with the actual production data. |
