Abstract
PURPOSE:To make the advantageous cope and the effective edging work possible in case of the different slab thickness and the different draft percentage of the edging work, by forming the caliber between plural pairs of collars installed on the roll drum, and by making at least one of the pair of collars to be movable in the direction of roll shaft. CONSTITUTION:The stationary collar 7 on the downstream side of the pass line is formed in one body with the roll drum 6, and the collar 7' on the upstream side of the pass line is made movable in the direction of roll shaft. The collar 7' is provided with the hollow hole 10, the protuberance 9 at the inner surface, respectively closely fittable to the drum 6 and the key groove 8, and the external flange 11; this collar 7' is also provided with the conical surface 13 to form the tapered caliber 12 by facing to the collar 7. The nut 15 is threaded so as to be engageable with the screw 14 of the drum 6; this nut 15 contacting with the back face of the collar 7' is integrated with the collar 7' by installing a pair of single split holding metals 16 closely contacting with the outer surface of the nut 15, and a pair of the flange stoppers 17 for tight stopping the flange 11 at the bottom of the holding metal 16. This pair of holding metals 16, mutually together with the nut 15, are rigidly set by the welding 18, etc. Hereby, if the nut 15 is rotated, the collar 7' can move together with the nut 15 to the specified position in the direction of roll shaft, and is fixed there to secure the size of the opening of the caliber 12.
