Abstract

PURPOSE:To adjust easily the deflection of a work roll by installing a backup roll chock housing and an intermediate roll chock housing held by the former chock housing and installing also a bending device for pressing vertically and pinch-holding the intermediate roll chock housing. CONSTITUTION:An upper backup roll-chock housing 14 and an intermediate roll- chock 16 are arranged in a state of holding the roll chock housing 16 between cylinders 17, 18 provided to the roll chock housing 14. An intermediate roll 12 has an outer chock and an inner chock, to which the cylinders 17, 18 are connected respectively. The cylinders 17, 18 are actuated during rolling to provide a bending to the roll 12 in order to conrol the shape of a rolled product. A large bending load can be applied to the chock 16 of intermediate roll 12 because of its double construction, and then the deflection of a work roll is easily adjusted. Furter, the positional adjustment between the rolls is easily performed because of its simple construction, and a product is inexpensively manufactured.
