Abstract

PURPOSE:To change rolls quickly by providing a hydraulic cylinder to the upper surface of a roll chock of upper backup roll and disposing a distance block between the hydraulic cylinder and a rolling down screw. CONSTITUTION:A hydraulic cylinder 21 is provided to the upper surface of a roll chock 9 of upper backup roll 8, and a housing case 26 is provided to the lower end of a rolling down screw 16. Further, a distance block 22 is disposed between the upper surface of cylinder 21 and the case 26. In case of changing a mill from four rolls to five ones, the cylinder 21 is first lowered and the block 22 is shifted to the central part of the mill, before raising the upper backup roll 8 and a work roll 6 together. Successively, a small-diam. roll 2 is inserted and the rolling down screw 16 is lowered. Then, the roll exchange is quickly performed because the rolls are rearranged by interposing and extracting the distance block.

The large-diameter upper work roll (6) is raised by a predetermined amount using the balance cylinder α4 via the axle box (7). Therefore, a predetermined gap is formed between the large-diameter upper work roll (6) and the lower work roll (4). Thus, the large diameter upper work roll (6) and the lower work roll (4
), insert the small-diameter work roll (2) assembled into the axle box (3) into the rolling line from the rolling mill working side, and then insert the axle box (3) into the rolling mill housing (
1), and then the large-diameter upper work roll (6) used as an intermediate roll is lowered by a predetermined amount by the balance piston a4, and the hanger (E) is lowered by a predetermined amount.
The upper retainer roll (8) is lowered by a predetermined amount, and the lowering screw (G) is rotated to lower the lowering screw (T) and the storage case (C) until the bottom plate contacts the fluid pressure cylinder Cυ. In this case, the fluid pressure cylinder (2
) is maintained in a state where it is raised by the stroke G.
