Method for determining shape of shift roll for rolling mill

Abstract

A method for determining a shape of a shift roll for a rolling mill, includes the steps of determining a necessary control amount distribution αi for a plate crown with respect to plate widths, based on a distribution of the number of plates rolled by a target rolling mill with respect to plate widths, and providing a maximum radius difference yA0 of the shift roll. The method further includes the steps of preliminarily determining a line yi of a roll radius distribution with respect to plate widths, based on the necessary control amount distribution αi and the maximum radius difference yA0, shifting the line yi of the roll radius distribution by a maximum roll shift to obtain a distribution ΔyBi of a roll gap change amount with respect to plate widths under the maximum roll shift, and smoothing sharp local changing part of the distribution ΔyBi of the roll gap change amount.
