Abstract

PURPOSE:To restrain an excessive sheet thickness, to improve a yield of product and to eliminate a sheet-thickness change in a longitudinal direction, by using the correcting quantity of sheet crown, obtained by adding a rolling order, a sheet width, a sheet thickness and a deformation resistance to a correcting factor of sheet crown, to set an aimed thickness at every rolling stock. CONSTITUTION:Meters 52 of sheet thickness and temperature are provided to the outlet side of a roughing mill 20, and their outputs are inputted to a controlling computer 50. A sheet-thickness meter 56 is also provided to the outlet side of a finishing mill 30, and its output is also fetched by the computer 50. The computer 50 computes an optimum finished sheet-thickness (aimed thickness) based on these detected values and a separately inputted information such as a kind of steel, a rolling order, a sheet width and a deformation resistance, and performs a finishing mill setting computation by using the aimed thickness, to perform the setting of each stand through a finishing mill setting device 54.
