ABSTRACT:
An apparatus for adding a metallic additive to a molten metal having a temperature higher than the boiling point of the metallic additive comprises a double-walled ladle structure having an adiabatic space formed between inner and outer containers which constitute the ladle structure, and a lid. The lid is adapted to close the top opening of the ladle structure so that a substantially hermetically sealed working chamber can be formed therein and above the surface level of the molten metal within the inner container. The working chamber is, when the lid is in position to close the ladle opening, held in communication with the adiabatic space through a plurality of vent passages.
