ABSTRACT:
A phase-separating member of annular form supplies a liquid phase, which converges towards a molten stream of metal. The liquid phase is distributed in the form of at least two layers, the upper layer meeting the metal stream at a distance h which is not greater than 300 mm from the bottom of the upper supply container, each layer forming an angle .gamma. greater than 30.degree. with the said stream and being intended to protect a proportion of the vertical extent of the stream h not greater than 600 mm. The invention is applicable to protecting casting streams of large diameter and considerable height, in particular between the ladle and the tundish in the continuous casting of slabs.
