METHOD OF OPERATING ROLLING DEVICE, CONTROL DEVICE FOR ROLLING DEVICE, AND ROLLING EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2021/005777
Kind Code:
A1
Abstract:
This method of operating a rolling device including a pair of rolling rolls provided to sandwich a metal plate comprises: a detection step for detecting a plate end position of the metal plate in a plate width direction at an output-side position of the pair of rolling rolls while rolling the metal plate by the pair of rolling rolls in a state in which an output-side tensile force applied to the metal plate is zero; a first leveling step for draft-leveling-controlling the pair of rolling rolls such that an outflow direction of the metal plate from the rolling rolls is along a transport direction of the metal plate in the rolling device when the detection result of the width end position of the metal plate in the detection step deviates from a reference position to one side in the plate width direction; and a second leveling step for, after the first leveling step, draft-leveling-controlling the pair of rolling rolls such that the outflow direction of the metal plate returns to the transport direction after the outflow direction of the metal plate from the rolling rolls is shifted to the outer side in the plate width direction with respect to the transport direction.
