Device for the continuous casting of billets, blooms, slabs and round bars, the device being associated with a crystalliser (10) containing the cast metal, the crystalliser (10) having sidewalls (11) which cooperate with cooling channels (16-24) defined by outer walls (15), the device comprising a plurality of devices located outside the sidewalls (11) of the crystalliser, the electromagnetic devices (18a, 18b, 18c) cooperating directly with the sidewalls (11) and being spaced apart longitudinally along the direction of sliding of the cast product, and fed in an independent, separate and differentiated manner from each other, the feeding being a function of the generation of a pulsating electromagnetic field in a direction substantially perpendicular to the axis of the crystalliser (10) and migrating substantially along the whole longitudinal extent of the crystalliser (10), the current pulses achieving a value of up to 100 kA. Method for the continuous casting of billets, blooms, slabs, round bars and other products, the method being associated with the use of a crystalliser (10) as indicated above. <IMAGE> |
