摘要:

针对凸度反馈控制策略较难选择的问题,结合鞍钢1580HSM精轧机组的配置情况, 从理论上推导出策略选择的方法,得出机架组合参与控制的策略,并推导出凸度偏差分配计算公式。在此基础上,开发了热连轧凸度反馈控制模型,完成了在线编程和调试,并投入了实际应用。生产数据统计表明,凸度反馈控制系统投入使用以后,凸度控制精度得到很大提高。

Abstract:

It is still a problem to choose the strategy of crown feedback. According to the configuration of Angang 1580HSM, a method of choosing strategy was studied, the strategy that all stands took part in control was gained and the formula of crown deviation distribution was established. And then, the control model for crown feedback was built, meanwhile, on-line programming and debugging were proceeded. The statistical data shows that crown control precision is improved with crown feedback control system.
