Abstract
Procédé de production de tôle d'acier électrique non directionnel dénué de nervures. Le procédé de la présente invention comporte une étape de brassage électromagnétique de l'acier fondu dans une zone où la température de l'acier fondu n'est pas supérieure à la ligne du liquidus et dont l'épaisseur n'est pas inferieure à 50 % de l'épaisseur totale de la coulée de façon qu'une portion non inférieure à 50 % de la région centrale de la plaque correspondant à une région centrale du produit laminé à chaud qui ne recristallise pas pendant le laminage à chaud se transforme en une structure équiaxe. Application à l'amélioration de l'état de surface de tôles d'acier électrique non directionnel.
