Title:
ROLLING APPARATUS AND METHOD OF CONTROLLING SHAPE OF ROLLED SHEET
Document Type and Number:
WIPO Patent Application WO/2008/065893
Kind Code:
A1
Abstract:
A rolling apparatus and method of controlling the shape of rolled sheet that even
in extremely thin sheet rolling, can attain excellent shape control. The rolling
apparatus comprises a rolling unit for performing rolling between vertically
arranged work rolls (12) to thereby obtain rolled sheet (P); a shape measuring
unit for measuring the shape of rolled sheet (P) obtained by rolling by means of
the rolling unit in the width direction thereof; and multiple injection nozzles
(32) arranged along the longitudinal direction of the work rolls (12), and further
comprises spray unit (30) for spouting work roll cooling oil (C) to the work rolls
(12); and a shape control unit for regulating the rate of work roll cooling oil
(C) spouted from the spray unit (30) and/or the temperature thereof in accordance
with the measurement information from the shape measuring unit to thereby control
the shape of the rolled sheet (P). The shape control unit has two control modes
conflicting to each other in the relationship of the rate of work roll cooling
oil (C) spouted from the spray unit (30) and/or the temperature thereof to the
measurement information from the shape measuring unit and switches the two control
modes in accordance with the thickness of the rolled sheet (P).
