摘要

"METHOD AND APPARATUS FOR ADDING LIQUID ALLOYING INGREDIENT TO MOLTEN STEEL" A descending stream of molten metal is directed from a ladle into a bath of molten metal in a tundish. Molten alloying ingredient is added to the molten metal, either directly to the descending stream within a shroud, or it is injected into the bath, through a sidewall of the tundish, at a region of turbulence. The molten alloying ingredient is protected from the atmosphere outside the tundish.
