Abstract

Abstract Translated from French Le dispositif met en oeuvre un champ électromagnétique produit par une bobine qui entoure le jet de métal liquide à confiner. The device implements an electromagnetic field produced by a coil which surrounds the jet of liquid metal to be confined. Le dispositif comporte une bobine 2a qui entoure le jet 6a et des moyens pour faire parcourir la bobine par un courant alternatif dont la fréquence est inférieure à l'inverse du produit de la perméabilité magnétique du métal liquide par la conductivité électrique de ce métal et par le carré du rayon du jet de ce métal après confinement, en unités cohérentes. The device comprises a coil 2a which surrounds the jet 6a and means for traversing the coil by an alternating current whose frequency is less than the inverse of the product of the magnetic permeability of the liquid metal by the electrical conductivity of this metal and by the square of the radius of the jet of this metal after confinement, in coherent units. Application notamment à la coulée de l'acier, de l'aluminium et du cuivre liquide ou de leurs alliages. Application in particular to the casting of steel, aluminum and liquid copper or their alloys.
