<P>PROBLEM TO BE SOLVED: To provide a rolling device easy in recombination of a rolling roll and low in manufacturing cost, and to provide the rolling roll. <P>SOLUTION: The rolling device includes the rolling roll 10c in which a plurality of calibers 23, 25 corresponding to a plurality of stands S3, S5 are molded. The common rolling roll 10c can be attached to the plurality of stands S3, S5. The calibers 23, 25 corresponding when the rolling roll 10c is attached are disposed so as to be situated at the same positions as a pass line P. When recombining the rolling roll 10c, the rolling roll 10c needs only be re-attached to other stands S5, S3 and hence working is easy. Since there is no need to reverse the rolling roll 10c and a connection part 14 needs only to be disposed on an end of one roll neck 11, the manufacturing cost is low. <P>COPYRIGHT: (C)2012,JPO&INPIT |
