Abstract
A cold rolling facility includes: a heating device; a tandem mill including a plurality of rolling mills; a meandering-amount measuring unit; a meandering-movement correction device; a shape measuring unit; a shape controller configured to control a shape of a steel sheet after being cold-rolled by the rolling mill located on the uppermost stream side; and a controller configured to control operations of the meandering-movement correction device based on a measurement value of a meandering-movement amount of the steel sheet by the meandering-amount measuring unit to control a meandering movement of the steel sheet before being heated, and configured to control operations of the shape controller based on a measurement value of a shape of the steel sheet by the shape measuring unit to control the meandering movement of the steel sheet that is attributed to cold rolling of the steel sheet by the tandem mill.
