Ladle shroud for metal casting system

A method of distributing molten metal to be casted, comprising:

• transferring the molten metal from a ladle to a ladle shroud via an inlet of the ladle shroud, the ladle shroud defining an internal flow passage;
• increasing a velocity of the molten metal through the ladle shroud from the inlet of the ladle shroud to a constriction in the internal flow passage of the ladle shroud located downstream of the inlet, the constriction defining a cross-sectional area that is less than a cross-sectional area of the internal flow passage anywhere upstream of the constriction;
• and
• outputting the molten metal from an outlet of the ladle shroud into a tundish positioned below the ladle, the constriction being substantially aligned with an elevation of a level of the molten metal in the tundish.

A ladle shroud for fluidly connecting a ladle to a tundish of a casting system, the ladle shroud comprising:

• a wall extending circumferentially around a central axis to define an internal flow passage, the wall having an inlet end defining an inlet of the internal flow passage and an outlet end defining an outlet of the internal flow passage, the internal flow passage having:
• a converging section extending from the inlet to a constriction located between the inlet and the outlet, the constriction defining a cross-sectional area that is less than a cross-sectional area of the internal flow passage anywhere upstream of the constriction, the cross-sectional area of the internal flow passage decreasing along the converging section;
• and
• a diverging section extending from the constriction to the outlet, the cross-sectional area of the internal flow passage increasing along the converging section.
