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.
