    摘要： A rolling mill for rolling metal strip (11) moving in a horizontal rolling direction, has work rolls (1) which engage the strip and are supported vertically by backup rolls (2) through which drive is applied. The work rolls (1) are supported in the horizontal rolling direction by support rollers (4) contacting them at locations confined to intermediate regions between the work regions and bearings (8). The work rolls are shiftable in the horizontal rolling direction. To provide control of the horizontal forces during rolling, there are position control means (5,7) for the support rollers operable to move and locate the support rollers so as to shift the work rolls (1) to a predetermined location at which the vertical axial plane of the work rolls (1) is offset in the horizontal rolling direction from the vertical axial plane of the backup rolls (2). The support rollers (4) maintain the work rolls at the predetermined location during rolling.

    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.

    摘要： Gauge control method and apparatus for a multi-roll type upright rolling mill includes displaceable rolls (4, 5) which are movable not only in a first direction in which a material to be rolled (1) is compressed but also in the axial direction thereof or in a direction in which the axis of the displaceable roll is inclined at a variable angle (9) relative to other rolls (2, 3; 6, 7) as viewed in a horizontal plane, the other rolls (2, 3; 6, 7) being movable in the first direction. Position of (b, 6) the displaceable rolls (4, 5) is detected, and in dependence on the displacement (δ, θ) of the displaceable roll, coefficient of mill stiffness (K) of the whole rolling mill and those (M) among the individual rolls are arithmetically determined. A roll gap (S) defined between the rolls (2, 3) serving for rolling work is arithmetically determined on the basis of the arithmetically determined coefficients of stiffness (K, M), a rolling load (P) and roll bending forces (Q) applied to the individual rolls (2, 3; 4, 5; 6, 7) detected by respective detectors (10, 12, 14). Rolling reduction set by a screw-down device (23) of the rolling mill is controllably regulated in dependence on the roll gap (S). A high precision gauge control is realized by considering variations in the coefficients of mill stiffness (K, M) brought about by the roll shifts and changes in the roll bending forces (Q).
