摘要： A nozzle for casting steel comprises an inlet portion, an elongated portion extending along a longitudinal axis from the inlet portion, an outlet portion comprising a front port, and a pouring bore. A planar cut of the nozzle outlet portion along a plane normal to the longitudinal axis comprises the outline of the outer peripheral wall of the outlet portion of the nozzle defined by the wall perimeter and the wall centroid of the area defined by said wall perimeter, and a first transverse axis passing by the bore centroid and extending along a direction parallel to the orthogonal projection of the front port direction onto the plane of the cut. The nozzle comprises no front port extending along a direction opposite to the direction of the first front port with respect to the longitudinal axis and belonging to the plane defined by the longitudinal axis and the front port direction. The distance from the wall centroid to the outer peripheral wall measured along the first transverse axis on the side of the front port is greater than the same distance measured on the side opposite the front port.

摘要： 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.

摘要： A lance for top injection of a fluid in metallurgical vessels comprises an inner tube, a refractory sheath surrounding the inner tube, an anchoring point rigidly coupled to said inner tube and at least partially embedded in the refractory sheath, an annular gap separating the inner tube from the refractory sheath; at least one annular guide surrounding the inner tube and comprising: an annular portion circumscribing the inner tube, and at least two anchor protrusions rigidly extending transversally from the annular portion and at least partially embedded in the refractory sheath, wherein a guide gap is formed between the annular portion and an outer surface of the inner tube. The at least two anchor protrusions are distributed over the external surface of the annular portion, separated from one another by an angle comprised between 90° and 270°.
