PURPOSE:To shorten the working time for rearranging a rolling stand, and to automate this rearranging work for the rolling stand, by putting a prepared stand on one side of a turntable approaching to a foundation of the mill, by transferring a used stand onto another side of the turntable, and by 180 deg. turning the turntable. CONSTITUTION:A new stand is prepared by insetting a new rolling roll and by connecting a cable bearer 38; this new stand is put on the rails 33, 34 installed on one side of a turntable 3. A used stand 1 is released from the fixed state and is moved to the right along the rails 22, 23, by a stand driver 13; hereby, the used stadn 1 is transferred from the foundation 2 onto the rails 31, 32 installed on the table 3 and is stopped therein. The table 3 is then 180 deg. turned in the arrowed direction by a table driver 4, and is stopped when the rails 33, 34 are aligned with the rails 22, 23 installed upon the foundation 2. The new stand is then moved to the left, is transferred onto the rails 22, 23, and is stopped and fixed therein. |
