冷连轧机带钢切边宽度自动设定研究

Research on trimming width automatic setting of cold tandem mill

宽展是冷连轧机切边剪切边宽度设定的重要考虑因素。影响宽展的因素较多,若考虑各影响因素,建立宽展模型十分困难。为此,在满足生产需求的前提下,通过大量数据分析,拟合出宽展系数计算多项式,进而可计算出满足需求的考虑宽展的切边剪宽度设定值,并通过自动化系统的改造实现了切边剪宽度的自动设定。

The spread is an important factor to be considered in the trimming width setting process.Considering all the influence factors of spread to accurately calculate the spread is very difficult in pickling tandem mills.Through data analysis and data fitting method to construct the spread coefficient calculation polynomial function,the trimming width setting value could be calculated,and the control system to achieve automatic trimmer width setting were carried out.
