ABSTRACT:
Additives in the form of a wire-like object are introduced through a tube into the interior of molten metal bath. The wire in the tube is surrounded by a pressurized gas which prevents metal from entering the tube. Since the tube extends close to the bottom of the bath, the additives melt near that bottom and are distributed in the bath through convective flow.
