    摘要： To eliminate a vertically asymmetrical deflection, a rolling mill comprises a device for measuring horizontal deflections of upper and lower work rolls 2, 3 during rolling, a device for comparing values measured on the upper and lower sides and calculating the difference therebetween, and a horizontal deflection controller for determining whether the difference exceeds a predetermined range or not and imparting a horizontal bending to at least one of the work rolls. To eliminate a transversely asymmetrical deflection, a rolling mill comprises a device for measuring horizontal deflections of at least one of the work rolls at axially spaced positions during rolling, a device for comparing values measured on at the axially spaced positions and calculating the difference therebetween, and a horizontal deflection controller for determining whether the difference exceeds a predetermined range or not and imparting a horizontal bending to the one work roll at at least one of the axially spaced positions. This prevents an adverse effect by the work rolls being horizontally deflected in a vertically or transversely asymmetrical way, reduces the diameter of the work rolls, and increases the allowable rolling load. Stable rolling of high-quality strips with good shape or flatness is thus achieved.

    摘要： A rolling mill has a work roll (1), a back-up roll (2) for supporting the work roll (1) vertically and driving it. A plurality of horizontal support rollers (4,6) contact the work roll at barrel diameter outside the rolling region and at both horizontal sides of the work roll and act to fix the position of the work roll in both horizontal directions during rolling and to oppose horizontal rolling forces. In order to reduce the bending of the work roll during rolling, there are provided means for applying horizontal counterbending forces to the work roll comprising members (5,7) e.g. rollers, contacting the work roll at locations axially further from the rolling region than the support rollers (4,6) and actuator means (14) for urging the members (5,7) against the work roll. The counterbending forces being in the same direction as the net horizontal force applied to said work roll by said back-up roll and the material being rolled. Preferably at least one condition of said work roll is sensed during rolling, and there are control means acting during rolling to control the counterbending forces in dependence on the sensed condition.

    摘要： A widthwise-compressing machine for applying a compression force through press tools to a material (1) to reduce a width of the material while applying vibrations to said material (1) to forcibly vibrate said material has a compression unit (3) for producing a compression force forming a working force, and a vibration-applying unit (4) for applying the vibration to said material (1). The vibration-applying unit (4) is provided independently of the compression unit (3). In the widthwise-compressing machine, when the material (1) is plastically worked, the material can be vibrated at an extremely high frequency to make it possible to resonate the material, thereby allowing the plastic-deformation thereof to be promoted.

    摘要： An object of the invention is to provide a cold rolling mill and a cold rolling method which are able to effectively carry out rolling lubrication and cooling and roll at a high speed and under high rolling pressure while maintaining a high surface quality.
    Rolling lubrication oil (12) is supplied from spray headers (10) for lubrication at an inlet side of a rolling material (1), cooling water (13) is supplied onto the surfaces of work rolls (2) at an exit side of the rolling material (1), and the cooling water (13) is prevented by partition plates (11a) or jackets (17) from being scattered and adhered to the rolling material (1). Further, the rolling lubrication oil (12) and cooling water (13) are collected by a pan (3), separated by a separation tank (4) and recirculated to be used again.
