Abstract

PURPOSE: To facilitate the arranging of upper and lower work rolls through retention of the upper backup roll chock to a mill housing in such a manner that the roll opening increases only during the arrangement of the work rolls of four-stage rolling mills.
CONSTITUTION: When a reduction screw is raised, an upper backup roll chock 13 lifts by a thrust of a cylinder 21 equipped with a lower backup roll chock 15 to increase the opening of the upper and lower work rolls 18 and 20. In this manner, getting in contact with a stopper 22, the chock 13 stops. While the chock 13 lifts, the upper work roll chock 17 is received with a chock receiver and goes up held together with the receiver. Then, when a projection 23 of the chock 13 is retained with a metal support 24, the center shaft of rolls 18 and 20 are maintained at a fixed space as well as at a fixed position with respect to a mill housing 11. The end of the roll shaft is positioned between a group of wedges 41 on a roll shaft end catcher 4 on a roll arranging carrier 2.
