ABSTRACT:
A tundish is provided with a mixing zone below an entry station where a stream of molten metal from a ladle enters the tundish. The mixing zone utilizes the force from the ladle stream to create sufficient turbulence for mixing alloying elements, particularly alloying elements such as lead having density greater than that of the molten metal with the metal in the tundish. The invention also includes a process for uniformly mixing alloying element with molten metal in the tundish. The process is particularly suited to making lead-bearing free machining steels on a continuous caster.
