Abstract
PURPOSE: To make the deflection of the work roll maximum for cold-rolling a convex thin sheet, and to improve the productivity, by arranging a six high rolling mill behind the finishing mill, and by optimizing the shifting position of the intermediate roll and the roll bending force.
CONSTITUTION: A six high rolling mill, whose upper and lower intermediates roll 2 are movable in the direction of roll drum, whose upper and lower work rolls 1 have ≤600mm diameter, and which is equipped with a roll bender capable of making the work roll diflect into a convex and concave shape, is arranged in each of at least four or more of latter stands of a hot finishing mill. Then, the upper and lower intermediate rolls 2 are shifted in the direction of longitude of th roll drum in order to make the effect of deflection of the work roll 1 possible to be displayed to the maximum limit, and a convex thin sheet, having a thickness difference between the middle part and both side edges, is rolled.
