Abstract:Strip shape is an important quality indicator of precision cold-rolled strip. Its control technology is the key, core and difficult technology in strip rolling process. Aiming at ABB pressure magnetic shape meter which is widely used in the domestic cold-rolled strip steel, the work principle, installation requirements and shape control means were clarified. Furthermore, it analyzes the effects combined with field application in the 1750mm tandem cold rolling production line. The primary and secondary control ability was strong, while the shape control of higher order needs to be verified. In recent years, domestic research on shape control theory and equipments have made considerable progress, and have achieved industrial applications.
