Title:
CAMBER CONTROL DEVICE FOR CONTINUOUS ROLLING MILL
Document Type and Number:
WIPO Patent Application WO/2024/057454
Kind Code:
A1
Abstract:
Provided is a camber control device for a continuous rolling mill, capable of reducing a camber in a tip part of a rolling material and suppressing the occurrence of telescoping of a steel strip coil. In this invention, a tip camber measurement unit calculates a tip camber measurement value at a rolling material tip part on the basis of a meandering amount of the rolling material detected by a meandering amount detector. A camber rectification leveling computation unit calculates a camber rectification leveling amount on the basis of the tip camber measurement value. A tip leveling setting unit sets a tip leveling control length and a tip leveling correction amount for reducing the tip camber for a reduction leveling device of each rolling stand. A reduction leveling control unit adjusts the reduction leveling device to a tip-leveling-correction-amount-added position before the rolling material enters the each rolling stand and adjusts the position of the reduction leveling device in such a manner that the tip leveling correction amount gradually decreases after the rolling length at the each rolling stand has reached the tip leveling control length.
