A cold rolling facility according to an aspect of the present invention heats steel sheets transferred sequentially, by a heating device, and sequentially cold-rolls the steel sheets after being heated, by a tandem mill. The cold rolling facility includes a meandering-movement amount measuring unit, a meandering-movement correction device, a shape measuring unit, a shape controller, and a controller. The meandering-movement amount measuring unit measures a meandering-movement amount of each of the steel sheets before being heated by the heating device. The meandering-movement correction device corrects a meandering movement of the steel sheet before being heated by the heating device. The shape measuring unit measures the shape of the steel sheet after being cold-rolled by a rolling mill located on the uppermost stream side in the tandem mill. The shape controller controls the shape of the steel sheet after being cold-rolled by the rolling mill located on the uppermost stream side. The controller controls the meandering-movement correction device based on the measurement value of the meandering-movement amount to control the meandering movement of the steel sheet before being heated, and controls the shape controller based on the measurement value of the shape of the steel sheet to control the meandering movement attributed to the rolling operation of the steel sheet. |
