Abstract

PURPOSE:To prevent a slab from buckling during a push-in rolling by fixing plural guide rollers to rigid frames each, setting those frames to a rolling mill stand and enabling those frames to move up and down. CONSTITUTION:A push-in rolling mill provided with a guide device 13 consists of a stationary stand 10 and a moving stand 11 movable in the passing direction of a slab. The stand 11 is joined to the stand 10 by plural connecting bars 12 during rolling. In rolling, the slab 5 to be rolled is subjected to a compressive force between the stands 10 and 11 and tends to buckle in up and down directions, but is held to avoid buckling by a couple of rigid upper and lower frames 14a and 14b constituting the device 13 and plural rollers 15a and 15b set on the frames 14a and 14b to be freely rotatable. The position of those rollers 15a and 15b is able to be set at an optimum position in accordance with a plate thickness or the height of a passing plate.
