Abstract
The sheet profile of a strip on the outlet side of a final stand coincides with a desired value without deforming the shape of the strip, by using a hot strip finish rolling mill having a number of rolling stands disposed sequentially. The rolling mill employs feedback control of upstream stands to reduce the error between a sheet profile measured by a sheet profile meter disposed at the outlet side of a selected stand and a desired sheet profile. The selected stand is the stand where the sheet thickness of the strip is at the percentage sheet crown critical sheet thickness. The sheet profile measured by the sheet profile meter is used to control the downstream stands using feed-forward control to make the sheet profile on the outlet side of the final stand coincide with the desired sheet profile.
