[Object] To provide a rolling apparatus that enables an operator to recognize the rolling status such as the behavior of the steel sheet entering the rolling stand and enables a stable rolling process. [Solution] A rolling apparatus 10 includes a plurality of rolling stands 11 each including a pair of rolling mills 12, and an imaging unit 15 provided between adjacent rolling stands 11A and 11B, the imaging unit 15 being configured to image a steel sheet 1 entering a pair of rolling mills 12B of the rolling stand 11B from an upstream side of the rolling stand 11 A located on a downstream side in a rolling direction. The imaging unit 15 is disposed so as to satisfy the following equation (1), on the upstream side in the rolling direction Z of the rolling stand 11B, in a central portion in the width direction of the steel sheet in an area P in which the steel sheet 1 is able to be conveyed: 2 × L × tan ± / 2 > W max
wherein L represents a distance in the rolling direction between the rolling stand 11B located on the downstream side in the rolling direction and the imaging unit 15, ± represents a horizontal viewing angle of the imaging unit, and W max represents a maximum width of the steel sheet 1. |
