Method for crystallizer electromagnetic stirring and corresponding crystallizer.

摘要

Method of electromagnetic stirring for crystallisers, of the type including plates or based thereon, employed in the continuous casting of billets, blooms, rectangular slabs, round pieces, using the method means for generating a magnetic field which interacts with the metal cast inside the crystalliser, the method being characterized in that it includes the circulation of electric currents (13) directly in and along the sidewalls of the crystalliser (10), the main component of flows (13) a direction parallel the axis (12) casting the crystallizer (10) and having a direction and a desired intensity, generating currents (13) of the electromagnetic forces with a direction perpendicular to the axis (12) cast with the function of obtaining a separation of the metal skin with respect to the sidewall of the crystalliser solidifies and a consequent reduction in l friction between the skin and the sidewall.
