Abstract
A method and apparatus are provided for making steel alloys directly in a tundish. Base steel enters the tundish from a ladle. An alloying chamber having a plurality of inlets is positioned above a tundish drain. An alloying material (for example, a wire including one or more alloying ingredients) is fed into the alloying chamber through a feed pipe originating above the liquid level in the tundish. Molten base steel enters the alloying chamber through the inlets and is mixed with the alloying material to make a steel alloy, which exits through the drain. The method and apparatus are especially suitable for making small order quantities of alloy steel of less than one ladle volume.
