FIELD: metallurgy.
SUBSTANCE: invention relates to the field of metallurgy. Submerged nozzle (1) comprises inlet portion (1A) located at a first end of the nozzle and comprising inlet orifice (18), elongated portion (1B) defined by an outer peripheral wall along first longitudinal axis (X1) from inlet portion (1A) to outlet portion (1C) comprising the second end of the nozzle. Peripheral wall of portion (1B) and the peripheral wall of portion (1C) are centered relative to longitudinal axis (X1) along the entire length of the nozzle. At the level of first front port (35), channel (50) runs along second longitudinal axis (X2) parallel to first longitudinal axis (X1) and is displaced relative thereto in the direction opposite to first front port (35). Peripheral wall of nozzle, not extending through in the direction opposite to the direction of port (35). In the section plane of outlet portion (1C) of the nozzle, channel centroid (50x) and wall centroid (1x) do not coincide and are separated by distance d≠0, and a segment extending along first transverse axis (Y) from channel centroid (50x) to outer edge (1P) of the wall has length (L1) that is longer than length (L2) of the segment extending from wall centroid (1X) to the point the intersection between first transverse axis (Y) and outer edge (1P) of the wall.
EFFECT: improved control of metal jets and uniform metal flow.
