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.
Claims5
A process for the treatment of molten metal by the introduction of a reactive additive into the molten metal which comprises introducing said molten metal into a reaction chamber through at least one entry channel which overlaps with a side of the reaction chamber to provide at least one slot at the end of said entry channel opening into the chamber over at least a substantial portion of the length of the side of the chamber above the bottom thereof, causing the molten metal to flow through said slot thereby producing at least one cascade of molten metal which flows downwardly into said chamber, introducing said reactive additive into said chamber above the cascade whereby said additive is rapidly drawn under the molten metal by the flow of the cascade, and recovering the treated molten metal.
