A process is described for treating molten metal with a particulate treating agent. A melt of a metal, e.g. aluminum, is provided in a treatment vessel such as a ladle and a mixing impeller is positioned substantially below the surface of the molten metal. The impeller comprises a plate with a series of spaced blades extending from the surface of the plate. This impeller is adapted to provide high shear mixing with minimum vortex. While rotating the impeller on a substantially vertical axis, particulate treating agent is fed by way of an injection tube below the surface of the molten metal and into the region between the axis and periphery of the impeller. This causes a high shearing action in the region of the blades whereby the treating agent is quickly broken down into finely divided droplets and which are circulated within the molten metal.

L'invention concerne un procédé de traitement de métal fondu au moyen d'un agent de traitement particulaire. Une fonte d'un métal, par ex. d'aluminium, est alimentée dans une cuve de traitement telle qu'une poche de coulée, et une turbine de mélange est disposée essentiellement en dessous de la surface du métal fondu. Ladite turbine comporte un disque présentant une série d'ailettes espacées s'étendant à partir de la surface du disque. Ladite turbine sert à mettre en oeuvre un mélange à cisaillement élevé et tourbillonnement minimal. Lorsque la turbine tourne autour d'un axe essentiellement vertical, un agent de traitement particulaire est alimenté par l'intermédiaire d'un tube d'injection en dessous de la surface du métal fondu, et dans la zone située entre l'axe et la périphérie de la turbine. Ainsi, il est possible de mettre en oeuvre un cisaillement élevé dans la zone des ailettes, et de diviser rapidement l'agent de traitement en fines gouttelettes circulant dans le métal fondu.
