PROCESS AND FACILITY FOR SHEARING TO LENGTH STEEL BARS COMING FROM A ROLLING MILL

摘要

A process for shearing to length steel bars coming from a rolling mill comprises the steps of: feeding the continuous rolled product to a first collecting chamber, which is a part of a braking/distributing apparatus which brakes and distributes the sheared bars and comprises a plurality of said chambers, which are stepwise mobile in sequence, in phase with the shearing of the bars; shearing to length a first bar and introducing the leading end of a second bar, following the first bar, to a second collection chamber; shearing to length said second bar and, by means of the shifting of said collection chambers, discharging said first, braked bar onto conveyor means. A facility for practicing the above briefly disclosed process comprises the combination of at least one shear (10), for shearing to commercial length the bar exiting the rolling mill and of a braking/distributing apparatus (11) for braking the sheared bars and distributing them onto conveyor means which perform the task of sending said bars sheared to length, while simultaneously cooling them, to devices where bundles or bars are formed, tied and stored. The apparatus (11) can comprise, e.g., a plurality of coaxial drums (13) each provided with circumferential seats, or collection chambers (16) inside which a bar (17) sheared by the shear (10) is received and braked by means of braking means The operation of the shear and the rotation of the drums (13) take place in phase, so that at each operating cycle a bar is discharged from the drums (13) onto the conveyor means.
