Abstract

PURPOSE: To quickly, exactly adjust the height of a pass line, by providing an elevating device in the rolling rolls in order to make them elevatable.
CONSTITUTION: After completing a rolling pass, an upper backup roll 3 is lifted up and a work roll 2 is withdrawn from a mill housing 1; next, by driving a lifting cylinder 12 so as to elevate, an interlocked V-saddle 11 also goes up and touches a drum of a lower back-up roll 4; hereby, a chock of the lower backup roll 4 is lifted up. As a result, a gap is formed between the pressure blocks 5, 8 and the bottom of the chock of the lower backup roll 4; hereby, a horizontal movement of the blocks 5, 8 become free. After setting the height of the blocks 5, 8 by suitably combining diameters of the work roll 2 and the backuprolls 3, 4, a shft cylinder 6, a couple of shift cylinders 7,9, or a shift cylinder 10 is actuated so as to set the work roll 2 in the housing 1; hereby, the pass line is accomplished.
