ABSTRACT:
A porous layer consisting of sintered material containing metal powder or ceramics powder is provided as the inner surface of a mold for use in continuous metal casting, and a shielding plate is provided on the outside of this porous layer. A gas is supplied in a gap portion formed between the porous layer and the shielding plate and the gas is spouted out from the porous portions in the porous layer into the inside of the mold, thereby forming a gas film between the inner surface of the mold and the molten metal. Electromagnetic coils are interposed between a stiffening plate and sandwiching frames around the mold and hanger frames supporting them. An annular cylindrical partition wall surrounding a nozzle is provided between the mold and a tundish, and a water-cooled reflecting plate having an annular downward reflecting surface is also provided therebetween.
