Aiming at the problems of the low crown controlling precision of thinner strip on 1580 mm hot strip mill, the obvious problems of the target profile reset were found through the analysis of lots of production data and through the research of the shape model of L2 on the 1580 mm hot strip mill, which affected the crown precision. By contrasting and analyzing lots of the shape data, the reasons for these problems were that the model calculation has the miscarriage of justice for the crown adjustable capabilities of the first three mills for the irrationality of some parameters, such as the flatness factors and thermal expansion factors. The optimized plans such as the optimization of the flatness dead band factor and the thermal expansion parameters for the improvement of the thin strip crown control precision were implemented on this hot strip mill. These optimized plans could resolve the problem of the target crown reset of this line, and the strip crown control precision was increased. Source
