Document Type and Number:
Japanese Patent JP2587171
Kind Code:
B2
Abstract:
PURPOSE: To make the profile of sheet on the outlet side of the final stand to hit the target value with high accuracy without generating defects in shape of a strip.
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 12A is mounted between the 4th stand F4 and the 5th stand F5 and the thickness of the strip S which is passed between those stands is made into 2 to 4mm. Control signal which is calculated with an arithmetic device 14 for controlling the profile of sheet based on measurement with the sheet profile meter 12A is outputted to sheet profile controllers 10A-10D, feedback control is executed to the stands F1-F4 on the upstream side, also control signal is outputted to sheet profile controllers 10E-10G and feedforward control is executed to the stands F5-F7 on the downstream side.
