Abstract

PURPOSE: To improve rolling efficiency by moving work rolls axially at every rolling of several hot strips thereby eliminating the high spots in said positions, in finish rolling.
CONSTITUTION: The pass line of a rolling material 1 is so set as to come to the center of the width of work rolls Wi, W'i. After one or several rolling materials 1 are rolled, the upper and lower work rolls Wi, W'i of each stand are selectively moved by a distance (a). In that state, the rolling materials are rolled in the same manner as above-mentioned and again the work rolls Wi, W'i of each stand are moved axially. It is equally well to determine a target plate crown together with its high spot permissible limit, measure plate thickness profiles with a profile meter, compare the actual plate thickness profiles and the permissible limit by a computer and decide whether high-spot controlling is necessary or not then to move the work rolls.
