Method to shear slabs arriving from a continuous casting plant and relative device

Abstract

Method and device to shear slabs arriving from a continuous casting plant, where the slabs (13) leaving the continuous casting plant are sent to be sheared to size so as to obtain sections which are speeded up and sent for rolling, there being included, immediately upstream of the shearing assembly, a pinch roll assembly comprising at least two opposite rolls (14a, 14b), the shearing assembly comprising shearing elements (11, 12) coordinated and arranged on opposite sides with respect to the feeding plane of the slabs (13) during the shearing step, the shearing elements (11, 12) acting on the leading end (13a) of the slab (13) in such a way as to cause the leading end (13a) to rise up in a controlled manner by means of lifting the lower shearing element (12) to a height which is at least more than the feeding plane of the slab (13), the opposite rolls (14a, 14b) of the pinch roll assembly arranged immediately upstream of the shearing assembly (10) being maintained closed in contact with the slabs (13) during the shearing so as to function as a contrast and abutment element.
