Abstract

PURPOSE:To make a mill capable of having a large crown or shape controlling capability by providing an interposing block which moves vertically with a roll chock and making the block vertically movable through a shifting frame. CONSTITUTION:For a rolling material with large sheet thickness, a roll chock 15 of a backup roll 13 is lifted through a lifting arm 18, and an interposing block 19 is also lifted by the chock 15. In this case, because a roll chock 16 of an upper roll 14 is lifted together with the block 19, there causes no special change in the positional relation between the chock 16 and the block 19 which supports the chock 16 through hydraulic cylinders 21. Accordingly, a roll bending work is sufficiently performed without being influenced by the change of the height of work roll 14 even when the roll 14 is largely opened.
