Abstract

A ladle adapted for treatment of molten iron with a reactant comprises a main chamber having sealed top and bottom ends. A teapot spout communicates with the bottom end of the ladle, and a dividing wall extends upwardly inside the main chamber from the bottom end of the ladle and forms a compartment within the main chamber. The compartment is adapted to contain the reactant. An opening in the top end of the main chamber allows placement of the reactant in the ladle compartment, and an airtight cover is mounted on the top end of the main chamber to cover the opening.
