    摘要： The invention provides a method for improving the luster of a metal sheet surface without deteriorating the productivity and also in reducing the difference in glossiness between the upper and lower surfaces of the metal sheet at the time of cold-rolling. By making the velocity, after rolling of the metal sheet, equal to or larger than the rotational circumferential velocity of the work rolls, and by rolling the metal sheet with upper and lower work rolls crossed with each other in such manner that an angle of slip scratches left on the metal sheet surfaces becomes 5 degrees or larger and shear deformation in the widthwise direction can be effectively given to the metal sheet just before rolling, thereby improving the surface luster of the metal sheet. In addition, in the case where luster of the metal sheet surface is improved by changing the cross angle between the upper and lower crossing work rolls, the sheet configuration is corrected by a configuration control actuator, depending upon the sheet configuration of the metal sheet after the cross angle is changed. Furthermore, the difference in glossiness between the upper and lower surfaces of the metal sheet is reduced by selecting the cross angles formed by the upper and lower crossing work rolls with respect to the direction at right angles to the rolling direction and also employing rolls having different surface roughness as the upper and lower work rolls.

    摘要： A rolling method and machine provides for decreasing the rolling load of work rolls of a rolling mill for a given reduction ratio achieved thereby. A pair of pinch rolls upstream of the work rolls have projections that form a large number of recesses in one or both surfaces of a metal workpiece. A lubricating agent is forced into the recesses in the region of contact between the workpiece and the work rolls. As a result, when the workpiece is rolled by the work rolls the lubricating agent is retained in the recesses such that the recesses progressively are flattened, thereby causing the lubricating agent to form a boundary film between the portion of the workpiece being rolled and the work rolls. The recesses are controlled to regulate the dimension of the length of each recess in the direction of rolling of the workpiece, to regulate the inclination of front and rear walls of each recess, and to regulate the total area of the recesses relative to the total surface area of the workpiece.
