冷轧连退线张力控制模型优化策略

Optimization on Tension Setpoint Model of Cold Rolling Continuous Annealing Line

针对某钢厂冷轧连退机组生产钢卷规格变化时张力波动问题,提出了张力数学模型及优化算法,将前后带钢张力波动降到最低,保证了生产连续稳定进行。

To the problem of the tension fluctuation while steel grade or dimension changed on cold rolling con tinuous annealing line, the tension mathematical model and optimization algorithm were put forward. Based on it, the tension fluctuation between two coils was reduced to minimum, and the production stability was assured.
