<p>PURPOSE:To make the profile of sheet on the outlet side of the final stand hit the target value with high accuracy without generating defects in shape of a strip by providing a roll profile meter on a rolling stand. CONSTITUTION:In the installation arrangement of a hot strip finishing mill which is constituted by successively providing a 1st stand F1 to a 7th stand F7, a sheet profile meter 20A is mounted between the 4th stand F4 and the 5th stand F5, a sheet profile meter 20B between the 5th stand F5 and the 6th stand F6 and the roll profile meter 22 on the 5th stand F5. At the time of executing feedback control to each stand on the upstream side and feedforward control to the stands F5-F7 on the downstream side based on a measuerement result with the sheet profile meter 20A, control accuracy is improved by using the value measured with the roll profile meter 22.</p> |
