    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 lubricant is supplied from headers (38) of lubricant supply units (5) onto surfaces of back-up rolls (3) at locations spaced from contact positions between a pair of work rolls (2) and a pair of back-up rolls (3). The headers (38) each include a lubricant spray nozzle (41) for spraying the lubricant under a pressure not lower than 3 kg/cm², a header cover (42) for confining the lubricant sprayed from the lubricant spray nozzle (41), an oil return line (44) for returning the surplus lubricant, and seal members (43) made of flexible material such as rubber. The work rolls (2) are provided with water wiping plates (6), and the back-up rolls (3) are also provided with water wiping plates (7). In a work rolls crossing type mill thus arranged, water films of cooling water deposited on the roll surfaces are removed to prevent the cooling water from mixing into the lubricant. Even if the water films are not totally removed, it is possible to surely plate out the lubricant for reliably lubricating between the work rolls (2) and the back-up rolls (3). Raw lubricant oil of the lubricant meets the following requirements; (a) the coefficient of friction between said work rolls (2) and said back-up rolls (3) is in the range of 0.04 to 0.1, (b) the viscosity is not larger than 80 Cst. at 40 °C, (c) mineral oil and synthetic ester not less than 5 % are contained as base oil, (d) a fatty acid in the range of 0.03 to 0.5 % is contained as an oiliness enhancer, (e) an extreme pressure additive not less than 0.1 % is contained, and preferably, (f) a surface active agent not larger than 0.5 % is contained as emulsifier.

    摘要： A five-high rolling mill includes upper and lower work rolls (1,2) of substantially the same diameter; upper and lower backup rolls (3,4) supporting the upper and lower work rolls (1,2) and having a larger diameter than that of the work rolls; an intermediate roll (5) located between one of the upper and lower work rolls and the associated backup roll and having a diameter larger than that of the work roll and smaller than that of the backup roll and a drum length larger than the maximum sheet width of a rolled material (6); work roll bending devices (10,11,12) provided on the respective roll ends of the upper and lower work rolls (1,2); and intermediate roll bending devices (13) provided on the roll ends of the intermediate roll (5). A skinpass rolling mill includes upper and lower work rolls (1,2) of substantially the same and large diameter; upper and lower backup rolls (3,4) supporting the work rolls (1,2), respectively; an intermediate roll (5) located between the upper work roll (1) and the upper backup roll (3) and having a diameter within a range between the diameters of the upper rolls; roll bending devices respectively provided on the roll ends of the intermediate roll (5); and roll bending devices respectively provided on the roll ends of the upper and lower work rolls (1,2), wherein the intermediate roll (5) has a larger drum length than the maximum sheet width of a rolled material (6) and smaller than the drum length of the work roll, and the roll bending devices for the lower work roll (2) are at least provided with a decrease bender mechanism. A multi-high rolling mill includes upper and lower work rolls (1,2) of substantially the same diameter and also a certain number of supporting rolls and a different number of supporting rolls for respectively supporting the work rolls (1,2) so that sections of the rolling mill above and below a rolled material (6) have sets of the rolls in different numbers; roll bending devices (13) installed on the supporting roll (5) directly supporting the work roll (1) in one of the roll sets having the larger number of the rolls; and roll bending devices (10,11) installed on the respective work rolls (1,2) of the upper and lower roll sets, wherein the supporting roll (5) in the one roll set having the larger number of the rolls, the work roll (1) in the roll set, and the work roll (2) in the other roll set having the smaller number of the rolls are controlled with control degrees of values gradually increasing in this order. A rolling method in a multi-high rolling mill is applied to a multi-high rolling mill including upper and lower work rolls of substantially the same diameter, upper and lower backup rolls supporting the work rolls, respectively, and an intermediate roll located between one of the upper and lower work rolls and the associated backup roll, wherein roll bending devices installed on the intermediate roll and roll bending devices installed on the work roll in the roll set where the intermediate roll is disposed are all actuated to control a composite sheet of a rolled material over its entire width, and roll bending devices installed on the work roll which is directly supported by the backup roll are actuated to control the sheet crown of the rolled material at its side end portions, thereby performing both the composite shape control of the rolled material and the control of the widths of the side end portions of the rolled material which are not to be rolled.
