<p><P>PROBLEM TO BE SOLVED: To provide a method and device of rolling in hot finish rolling for appropriately controlling a next rolling material to enter into a finish rolling machine by correctly and quickly determining presence of plate breaking of a tail end of a rolling material. <P>SOLUTION: A shape of the tail end of the rolling material is detected in a side of the finish rolling machine, and presence of the plate breaking is determined based on the detected shape of the tail end. When presence of the plate breaking is determined, the next rolling material is prohibited from entering into the finish rolling machine, while resumption of the rolling is not performed until no plate breaking residue is confirmed, and when absence of the plate breaking is determined, the next rolling material is allowed to enter into the finish rolling machine, and the rolling is continued. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
