易拉罐用铝合金带材宽幅冷轧机板形控制策略的改进

Improvement of Flatness Control Strategy for Wide Width Cold Rolling Mill in producing aluminum strip for cans

本文在阐述铝带宽幅冷轧机板形控制的基础上重点介绍了易拉罐用铝合金带材在冷轧轧制中板形的控制方法。以CVC六辊不可逆冷轧机为例介绍了不同板形控制手段的特点,并给出ABB板形仪用于易拉罐用铝合金带材轧制时控制器参数的优化方法。该方法的使用提高了产品质量,并显著降低了紧边断带率。

Based on the description of flatness control in aluminum wide cold rolling mill,this paper focus on introduces the method of flatness control strategy in aluminum can body strip cold rolling process.Taking CVC 6-Highnon-reversing cold rolling mill as an example,the characteristics of different type of flatness control actuators are introduced,and an parameteroptimization method for ABB Stress-meter flatness control system used in aluminum can body rolling is presented.The use of this method improves the quality of products and reduces the rate of tight edgestrip break.
