DEVICE AND METHOD FOR LEVELLING STRIP

摘要

Provided is an apparatus for correcting a rolled steel sheet capable of increasing correction efficiency by performing a plastic bending process at appropriate bending curvature depending on the thickness of a rolled steel sheet having the thickness less than that of a heavy material. The apparatus for correcting a rolled steel sheet comprises multiple correction rolls vertically and alternately arranged apart from each other along a process line of the rolled steel plate. The correction rolls include first rolls and a second roll which have different diameters. The two first rolls and the second roll are vertically arranged as a set. Multiple sets are vertically and alternately arranged to face each other along a process line.
