Abstract

Abstract

The weakness of traditional methods for flatness defect pattern decomposition was analyzed and a gaussion decomposition method for strip flatness defect patterns was presented. This method not only improves the regression accuracy of strip flatness curves, but also facilitates flatness control, especially in the control system of subsection cooling and altering convexity of a roller by local pressure.
