    摘要: Sliding closure at an outlet of a metallurgical vessel includes a housing fastened to the vessel, a slider unit coupled and longitudinally displaceable relative to the housing, and a respective cassette arranged in the housing and/or slider unit and which operatively retains a refractory closure plate having an opening for passage of medium from the vessel. The closure plate is fixable in and releasable from the cassette by interaction of structure on the cassette and housing or slider unit. This structure includes a retaining element and an elbow lever mechanism on opposite end sides of the cassette, and a corresponding receiver element and snap-in element on opposite sides of the housing or slider unit such that the cassette can be pushed into the housing or slider unit at an angle and fixed therein by pressure through engagement of the elbow lever mechanism with the snap-in element.

    摘要: 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.

    摘要: The invention relates to a ceramic refractory casting nozzle for metallurgical applications. The term “nozzle” includes all types of substantially tube-shaped refractory parts which allow a metal melt flowing through a corresponding casting channel. This includes, i. a. a so-called submerged entry nozzle (SEN) and a so-called ladle shroud.
