PROBLEM TO BE SOLVED: To provide a continuous casting method and a continuous casting apparatus, wherein metallic elements of low melting points or low boiling points are mixed with high yield and uniformly distributed in a slab. SOLUTION: (1) The method and the apparatus are a continuous casting method and apparatus for molten metal, wherein a partition wall to partition the molten metal is provided in a tundish, and metal vapors and/or metal particles are blown into the molten metal, which flows through a passage hole, with an inert gas from an opening made in the passage hole for the molten metal, which is formed in the partition wall. (2) The method and the apparatus are a continuous casting method and apparatus for molten metal, wherein metal vapors and/or metal particles are blown into the molten metal, which flows through a discharge hole, with an inert gas from an opening made in the discharge hole of an immersion nozzle. In the cases of (1) and (2), the flow rates of the molten metal flowing through the passage hole and the discharge hole are preferably≥1 m/s. COPYRIGHT: (C)2004,JPO&NCIPI
