Abstract

Method for producing light metal alloys, in particular aluminum alloys, characterized in that the desired alloying elements are first introduced into a vacuum furnace in which the vacuum is then made, after which light metal melt is introduced into the furnace chamber, by aspiration, in the form of a metal jet, thus subjecting it to a vacuum treatment to reduce the content of impurities such as hydrogen, sodium, oxides and other non-metallic particles contained therein, and by giving the jet of metal such a configuration with respect to the composition and pattern or flow design, such a length and such a speed and direction that the alloying elements dissolve easily and mix in the melt in the vacuum furnace, thereby Desired alloy grade is ready for casting immediately upon completion of vacuum treatment and alloying process.
