Abstract

Atomiseur destiné à la production de poudre de métal. Il comporte une chambre 17 d'atomisation délimitée par une enceinte 16 au-dessus d'un bain d'eau 13 de refroidissement et au-dessous d'un bassin de coulée 22. Des buses dirigent deux paires de jets d'eau vers le bas, de manière que les jets d'une première paire se croisent sur la coulée de métal provenant du bassin 22 pour lui donner la forme d'un ruban, et que les jets de la seconde paire se croisent sur ce ruban afin de l'atomiser en particules séparées. Domaine d'application : production de poudre de métal.
