<p><P>PROBLEM TO BE SOLVED: To continue rolling by automatic control even when failing biting between rolling rolls. <P>SOLUTION: In a method of manufacturing the rolled stock in which rolling is performed by gradually reducing the gap between the rolling rolls while making a material pass through reciprocatively between the rolling rolls a plurality of times according to a preset pass schedule, when failing in the biting of the material between the rolling rolls, the roll gap in a rolling pass when the direction of rolling is the same as the feeding direction of the material at that time is made into the state where the gap is widened than the roll gap which is set by the original pass schedule and also the pass schedule is corrected so that the roll gap in the rolling pass the direction of which is the opposite direction to the direction of that feeding is set to the roll gap according to the original pass schedule and rolling is performed according to the corrected pass schedule. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
