Abstract
PURPOSE:To improve a dimensional accuracy of rolled product, by fixing vertical roll chocks to clamping members during the rolling of a vertical roll to eliminate play due to gap. CONSTITUTION:Vertical roll chocks 3' equipped with a vertical roll 2 in its inside is moved to the left by rotating press-down screws 12 through a driving screw 11 rotated by the action of a screw-down motor 10. A pulse generator 14 detects the position of the roll 2 by detecting the rotation of the screw 11 and actuates a braking device 7 to stop the rotation of the screw 11 when the roll 2 reaches a prescribed position where the roll 2 should perform rolling, and simultaneously sends signal to a control panel 17 to move an electromagnetic valve 16 to the left. By these actions, fluid is sent out from a fluid supplying device 15 to actuate a clamping action device 9 so that the vertical chocks 3' is held powerfully to be fixed by clamping members 8.
