Abstract

PURPOSE: To withdraw the upper and lower rolls while their journals are suspended in an overhang condition by the journal holder and the spacer, and to carry out safely and rapidly the replacement of rolls, by moving a frame provided with the strip made journal holders for holding upper and lower roll journals toward the rolling mill side, and by inserting the spacer for holding the upper roll chock.
CONSTITUTION: The roll benders 37, 40, 45, 48 of the rolling mill are operated in order to make a gap h1 between the rolls 35, 43 and a gap between the rolls 35, 47 and between the rolls 38, 50. Then, the rods 22, 23 of the roll replacing apparatus 4 are withdrawn, a spacer 30 is attached to the tip of the rod, and the apparatus 4 is moved to the operating side of the rolling mill. The spacer 30 is inserted into a prescribed position between the roll chocks 36 and 39. Then, the roll bender 37 is operated so as to bring down the roll 35, and to make the spacer 30 hold the roll chock 36. The journal holders 14, 16 are brought down for holding the rolls 35, 43, 38 in an overhang condition with the journal holders 14, 16 and the spacer 30; hereby, the rolls 35, 43, 38 are withdrawn upon the truck 2 on the operating side and are replaced with new rolls.
