Analysis for the Computation Method of Crown on Hot Strip Production Line

Abstract

In this paper, the computation method of the strip crown is analyzed using the measured strip thickness data on a hot strip product line. The better quality of the strip is achieved for the smaller crown and the closer of the mean thickness to the nominal thickness. The polynomial approximation method for the transverse thickness distribution of the strip is used, and the different degrees of the polynomial are selected for calculating the strip crown. The calculated results are compared with the output of the measuring system in a rolling factory.
