High precision recognition and adjustment of complicated shape details in fine cold rolling process of ultra-thin wide strip
With development of the ultra-thin wide strip, more complicated shape problems begin to happen in the high-speed rolling process. A new shape method with high precision has to be proposed for recognition and adjustment of local composite shape defects, which is not only difficult to be detected exactly, but also easily affected by the various inevitable process factors in the practical rolling process. So, it is necessary to comprehensively take advantage of the deformation mechanism and the intelligent algorithm according to massive practical effective shape signals via focusing on the accurate shape signals and the exact local shape pattern as well as the co-regulation features. Just counting on combining the shape evolution mechanism and the intelligent property, more complicated local shape details can be revealed and controlled. Finally, many practical cases were calculated by the new model to verify the fine control effect of various shape defects, which is pretty helpful in recognition and adjustment of the ultra-thin wide strip.
