PURPOSE:To provide a titled rolling mill which can wind and mount an annular work around both rolls by the insertion and removal of an intermediate work roll and tension roll and can remove the product by constituting both the rolls in such a manner that the rolls can be inserted and removed in the axial direc tion of the rolls. CONSTITUTION:A mounting means 41 for a work 43 is inserted into a bearing hole 24 between holders 20 while the tension roll 22 is held by a roll rest 40. The roll 22 is inserted into the bearing hole 24 in the state of pinching the tension roll 22 by means of a pair of right and left pushers 38, 39. As a result, the annular work 43 is mounted to the roll 22. The holders 20 are returned to a horizontal position in this state and a forming tool 27 is slid leftward to press the work 43 by a forming part 29, by which the work is formed to the long elliptical shape shown by a chain line. A tensioning cylinder 17 is thereafter extended to insert the work 43 grasped by the roll 22 and the forming part 29 onto the extension line of the axial center of the intermediate work roll 12 existing in the standby position. The roll 12 is skewered in this state onto the work 43 so that the work 43 is wound and mounted around the two rolls 12, 22. The work 43 is rolled by pressing of a rolling-down roll 7. |
