提高1450热轧卷板头尾宽度精度的措施

The Measures to Improve the Accuracy of Head and Tail Width of 1450 Hot-rolled Coil

介绍唐山国丰热轧薄板厂在生产实践中提高卷板头尾宽度精度的经验,主要是在一级基础自动化中优化立辊位置控制器的参数和立辊短行程动作参数,让立辊短行程时的实际侧压行程及时达到设定值;在此基础上,充分发挥二级过程自动化的立辊短行程控制参数对板坯头尾的宽度控制功能。

The experiences of improving the accuracy of head and tail width of rolled coil in Tangshan Guofeng hot-rolledsheet plant are introduced. The edger position controller parameters and edger short stroke action parameters are optimized inprimary basic automation. The actual lateral pressure stroke edger reaches the set value timely. On this basis, edger shortstroke control parameters on the width of the slab head and tail control functions of second process automation is fully lever-aged.
