Title:

ROLLING APPARATUS AND ROLLING MONITORING METHOD

Document Type and Number:

WIPO Patent Application WO/2013/161780

Kind Code:

A1

Abstract:

Provided is a rolling apparatus that is capable of recognizing the state of rolling, such as the behavior of a steel plate caught by a rolling stand, and stably performing a rolling operation. A rolling apparatus (10) comprises: a plurality of rolling stands (11) that include a pair of rolling rolls (12), and imaging means (15) that is placed between adjacent rolling stands (11A and 11B) and images a steel plate (1) caught by the pair of rolling rolls (12B) of the rolling stand (11B) from an upstream side of the rolling stand (11A) which is disposed at the rolling direction downstream side; and the imaging means (15) disposed in a plate width direction central portion of a passable area (P) of the steel plate (1) at the upstream side in a rolling direction (Z) of the rolling stand (11B) in such a manner as to satisfy the relationship of the following formula 1: 2×L×tan(α/2)>Wmax…(1). Herein, L is the rolling direction distance between the rolling stand (11B) placed on the rolling direction downstream side and the imaging means (15), α is the horizontal viewing angle of the imaging means, and Wmax is the maximum width of the steel plate (1).
