Abstract
PURPOSE:To obtain a roll deflection correcting device excelling in correcting effect by roll bending, by applying a bending force to work roll and intermediate roll by means of a hydraulic cylinder, in a multi-stage rolling mill having an intermediate roll provided between work roll and backup roll. CONSTITUTION:An intermediate roll 14 consisting a pair with upper and lower halves is disposed between a work roll 12, which also consists a pair with upper and lower halves, and a backup roll 13, and a rolling material 11 is processed while it is passed between the pair of work roll 12. The width L1 of this intermediate roll is formed within 60 to 80% of the width L2 of the backup roll 13. At both ends of work roll 12 and intermediate roll 14, respectively, are provided inside bearing and outside bearing being spaced at a specified distance from each other, and a hydraulic cylinder is provided between these bearings. Due to the operation of this hydraulic cylinder, a bending force is applied to the rolls, so that the thickness form in the plate breadthwise direction may be corrected.
