Abstract

A method and its corresponding apparatus for the introduction of a reactive additive into a molten metal, the method of which is to transfer the molten metal from a vessel through a reaction chamber provided with an inlet and an outlet for the molten metal, reaction which is designed to ensure that for a given flow rate of molten metal there is always a predetermined amount of molten metal in the chamber and the latter is provided with an injector device that opens into the reaction chamber through which they can reactive additives are introduced into the chamber below the surface of the molten metal present in said reaction chamber.
