    摘要: A rolling mill has a work roll and a back-up roll for supporting the work roll vertically and driving it. A plurality of horizontal support rollers contact the work roll at barrel diameter outside the rolling region and at a 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 e.g. rollers, contacting the work roll at locations axially further from the rolling region than the support rollers and actuator means for urging the members 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: 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 four 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 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: To improve the productivity of the cold rolling facility by providing the cold rolling facility with a strip wiper free of dust and foreign matters suitable for high-speed rolling. The wiping ability was greatly improved by floating and supporting the wiper roll by the static pressure bearing of air of two-pocket type, and by variably adjusting the load range of the floating force in response to the plate width. At high-speed rolling exceeding 700 m/min which was incapable with the conventional roll wiper or tube wiper, the productivity of the cold rolling facility and the surface quality of the strip were greatly improved by applying to the cold rolling facility the wiping device whose wiping ability is equal to or better than the tube wiper at low speeds, and its effect is very large.

    摘要: In a tandem mill system, at least one first type rolling mill is arranged in the upstream side and at least one second type rolling mill is arranged in the downstream side. The first type rolling mill is of the so-called work roll crossing mill in which a pair of work rolls are inclined with respect to a pair of back-up rolls supporting the work rolls and simultaneously crossed each other in a horizontal plane to control transverse thickness distribution of a strip. The second type rolling mill is of the so-called HC mill which controls the strip crown and shape by a combination of axial movement of intermediate rolls and work roll bending. Such an arrangement makes it possible to increase a capability of controlling the strip crown and shape, particularly, a capability of correcting the quarter buckle, and eliminate a fear of causing scratches on the strip and roll surfaces, with the result of improved production efficiency. Plural lines of lubricant supply device are also provided to stop supply of a lubricant immediately before biting of the strip into the work roll crossing mill and start the supply again after the biting. A system of lubricating the work roll crossing mill is thereby improved.
