    Abstract: The invention relates to a process and an apparatus for the precise and continuous injection of a halogenated derivative, which is liquid at ambient temperature, into a liquid metal such as aluminum and aluminum-based alloys. The process involves withdrawing the halogenated substance from a tank, introducing it by means of a metering pump into a vaporizer which has been brought to a temperature at least equal to the vaporization temperature of the substance under the injection pressure, and entraining it in the vapor state by an inert gas stream towards an injection means opening into the center of the liquid metal.

    Abstract: The invention concerns an apparatus for active filtration and treatment of liquid metals and alloys and particularly to the purification of aluminum, magnesium, or alloys based on aluminum or magnesium, prior to molding. It comprises a detachable cartridge, closed at at least one end by a porous block based on grains of fritted flux and filled with grains of flux, solid at the temperature of the metal to be filtered. The cartridge may include a means for injecting an active or inert gas into the grains; it may be arranged in a heated, heat insulated ladle.
