ABSTRACT:
This invention relates to a method for the treatment of molten metal by introduction of a reactive additive and particularly to the treatment of molten iron by introduction of a nodularizer. The molten metal is introduced into a reaction chamber through one or more slots formed in one or more sides of the chamber thereby producing a cascade of molten metal which flows downwardly into the chamber. The reactive additive is added above the cascade and is rapidly drawn under the molten metal by the flow of the cascade.
