Abstract
Submerged nozzle (1) through which molten steel can be poured from a tundish into a mould, said nozzle comprising: a substantially tubular body (2), extending from a first end (3) to a second end (4); a passageway (5), extending through the tubular body (2) along a longitudinal axis (A) from the first end (3) towards the second end (4); at least one inlet port (6), opening into the passageway (5) at said first end (3); a plurality of outlet ports (8), opening into the passageway (5) in a region (7) adjacent to the second end (4); and at least one rotatable insert (10); whereas the submerged nozzle (1) with the at least one rotatable insert (10) is configured that a molten metal entering the submerged nozzle (1) at the at least one inlet port (6) flows through the passageway (5) and around the rotatable insert (10) and exits the submerged entry nozzle (1) via the plurality of outlet ports (8), such that a rotation of the rotatable insert (10) is driven by the stream of molten metal.
