Abstract

Un procédé de fabrication de granules à partir d'un métal en fusion consiste à produire un jet de métal en fusion qui est soumis, au niveau de sa sortie, à l'influence d'un champ électromagnétique alternatif qui varie dans le temps selon une certaine régularité et dont la direction du vecteur E(Boolean not)xH(Boolean not) coïncide avec la direction de la vitesse du jet, où E(Boolean not) est le vecteur de l'intensité du champ électromagnétique et H(Boolean not) est le vecteur de l'intensité du champ magnétique, de manière à générer à l'intérieur du métal en fusion des forces tridimensionnelle variant proportionnellement à la régularité des fluctuations du champ électromagnétique et initiant une désintégration forcée du jet en gouttelettes séparées. Le métal en fusion, au niveau de sa sortie, est soumis à une série d'influences impulsionnelles des forces tridimensionnelles, le cycle de répétition de la série étant égal au cycle d'auto-désintégration du jet, et le nombre de gouttelettes obtenues pendant ce cycle étant déterminé par le nombre d'impulsions dans la série, la dimension des gouttelettes étant proportionnelle aux intervalles de temps entre les impulsions dans la série. Le dispositif comporte un réservoir (1) destiné au métal en fusion et un manchon (2) relié par ses extrémités au réservoir (1) et formant un canal annulaire entourant un inducteur (3) relié électriquement à une première source de courant (4). Le manchon (2) possède une partie avec au moins une ouverture (5) située dans l'entrefer d'un electro-aimant (6) relié à une seconde source de courant (7), les deux sources de courant étant reliées l'une à l'autre. Les première et deuxième sources de courant sont conçues avec des paramètres programmables et sont directement reliés l'une à l'autre.
