ROLLING SITUATION OBSERVATION DEVICE, ROLLING SITUATION OBSERVATION METHOD, ROLLING DEVICE, AND ROLLING METHOD

WIPO Patent Application WO/2023/182277

A1

Provided are: a rolling observation technology that tracks moment-to-moment changes in the rolling situation at one specific point (a material point) on a sheet material that passes through a roll bite from before rolling until after rolling and makes it possible to easily observe the changes in situ; and a rolling technology that is based on observation results from the rolling observation technology. According to the present invention, a rolling situation observation device that observes a rolling situation during the rolling of a workpiece by passage of the workpiece through a roll gap provided between a pair of rolls that rotate in opposite directions comprises a rolling unit that rolls the workpiece by passing the workpiece through the roll gap while moving the axial centers of the pair of rolls at a prescribed speed toward the upstream side of the workpiece but keeping one point on the workpiece at a fixed position and a rolling situation observation unit that observes the rolling situation of the workpiece at a roll bite from the outside in the axial direction of the pair of rolls toward the workpiece.
