WIDTH PRESS METHOD IN HOT ROLLING, AND METHOD OF MANUFACTURING HOT-ROLLED METAL PLATE BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To perform the consistent operation of a hot rolling line 100 by solving a problem that a material 8 to be rolled cannot be moved in the conveying direction A because a hold roll 98 is non-rotatable while the material 8 is restricted when performing the width press of the material 8 by the hot rolling. SOLUTION: When any slip is detected during the operation of performing the width press or the conveyance of the material 8, the pressing of the hold roll 98 against the material 8 is temporarily opened while performing the conveyance immediately after the operation of performing the next width press.
