WIPO Patent Application WO/2017/111216
Kind Code:
A1
Abstract:
A strip shape correction device of the present invention is provided at an inlet side of a mandrel for winding a hot-rolled strip, so as to correct the shape of the strip, and comprises: a first shape measurement part for measuring the shape of the strip supplied to the inlet side of the mandrel; a shape correction part for correcting the shape of the strip by pressing a pressure roll, which is arranged to press the strip, with set target pressure force so as to allow the shape of the strip, which is measured by the first shape measurement part, to be corrected to a target shape of the strip on the basis of an elongation percentage by the pressure force and tension on the strip; a second shape measurement part for measuring the shape of the strip, the shape being corrected by the shape correction part; and a shape amendment part for amending the target pressure force by controlling the pressure force and tension of the shape correction part for the strip such that the shape of the strip, which is measured by the second shape measurement part, corresponds to the target shape of the strip.
