Abstract

Abstract

A strip profile along its width is correlative with strip flatness control. Conventional strip profile definitions cannot describe the abnormity of cross sections accurately, and affect strip profile quality and control precision. Multi-factor strip profile definitions were presented, which described strip profiles more comprehensive. Taking CVC mill as an example, based on the ANSYS finite element model, a coupling relation of strip profile factors was analyzed. It was proposed that the general control of strip profile factors and coupled control with flatness were difficulty and also the key to high-quality steel rolling.
