Abstract

A nozzle for casting steel contains an inlet portion, an elongated portion extending along a first longitudinal axis, an outlet portion and a pouring bore having a front port inlet. A planar cut of the nozzle outlet portion normal to the first longitudinal axis passing through the front port inlet contains the outline of the bore, the outline of the outer peripheral wall of the outlet portion of the nozzle, and a first transverse axis. In the planar cut, the bore centroid and wall centroid are distinct and separated by a distance, d≠0; and the segment extending along the first transverse axis, from the bore centroid, to the wall perimeter is longer than the segment extending from the wall centroid to the intersecting point between the first transverse axis and the wall perimeter.
