<p>PROBLEM TO BE SOLVED: To execute an approximate pass schedule by controlling the thermal crown of a work roll at the time of rolling according to a prescribed evaluation rule. SOLUTION: When rolling successively plural slabs according to a prescribed pass schedule, the method consists of a process judging if a target plate crown can be secured or not in the range of a prescribed finish rolling load to the thermal profile of the work roll at this point of time, a process determining the number of first slabs to which the target plate crown can be secured under the present thermal profile and the number of second slabs to which the setting of a rolling load is necessary to secure the target plate crown, and a process determining the water quantity distribution of the cooling device of the roll according to the numbers of the first and the second slabs and/or if the water quantity should be changed or should be maintained in a present state according to a previously set evaluation schedule.</p> |
