Abstract

PURPOSE:To facilitate the assembly and interchanging works for the roll, by installing a supporting member for putting the segmental backup roll on it in the housing, by attaching a push roll to the turning lever fixed to the axis of the backup roll, and by installing a device to turn this turning lever. CONSTITUTION:The titled multistage rolling mill is constituted as follows; an upper work roll 1 and a lower work roll 2 in diameter smaller than that of the upper work roll 1, and upper and lower backup rolls 3, 4, for backing up these work rolls 1, 2, are installed; an intermediate roll 5 in diameter equal to that of the upper work roll 1 is arranged between the lower work roll 2 and the lower backup roll 4; a segmental backup roll 8, built up by axially, successively arranging plural rolls 6 placing an arbitrary interval, is installed; a pusher 9 for giving a horizontal displacement to this segmental backup roll 8 is installed; a push roll 10 for transmitting above-stated horizontal displacement to the lower work roll 2 is interposed between the lower work roll 2 and the segmental backup roll 8. Additionally, a supporting member 14 for supporting the segmental backup roll 8 is installed within the housing 16; the push roll 10 is set to the turning lever 24, and a device 21 for turning the turning lever 24 is installed.
