Abstract
Apparatus for the late introduction of a particulate alloy when casting liquid metal, disposed between a casting ladle or an apparatus for the automatic feed of said metal and a series of moulds to be filled, characterised in that it comprises a jet of liquid metal of sufficient thickness, which is confined and in motion in a mixing chamber, for example a vortex, and a non-immersed introduction means (8) for the introduction of particles of alloy, imparting to said particles a speed and an energy sufficient for them to penetrate deeply into the interior of the liquid metal in the zone (4) of sufficient thickness, said zone being disposed in the vicinity of a casting orifice (5).
