Abstract
PURPOSE:To make maintenance easy, make possible stepless pass line adjustment inexpensively and prevent the decrease in working efficiency by building starcase type locker plates and adjusting liners to the roll changing truck provided to the underside of rolling rolls. CONSTITUTION:A changing truck 6 for exchanging of a backup roll 3 is disposed between the backup roll 3 and screw-down cylinder 4. Liner adjustment type locker plates 7 and staircase type locker plates 8 are disposed on the top surface side of the truck 6. The locker plates 8 lift the roll 3 by jacks 10 and are movable to arbitrary positions by cylinders 9. The pass line adjustment of the work roll of higher changing frequdncies is accomplished through stepless and rapid adjustment of the staircase type locker plates 8 with the screw-down cylinders 4. The pass line adjustment at the changing of the backup roll of changing frequencies 2 to 3 times a month is accomplished by the locker plates 7, whereby the rolling downtime is reduced.
