    摘要: An immersion nozzle for pouring molten metal, especially steel, from a pouring vessel into a mold of a continuous casting machine. The nozzle includes a substantially tubular upper part that can be attached to the pouring vessel and a lower part that has a broad side significantly larger than its narrow side at the opening end. The upper part has, at the end facing the lower part, a flared section that encircles the entry area of the lower part. A seal is provided between the upper part and the entry area of the lower part. The lower part has a support in the entry area. Holding elements are provided so as to touch the support of the lower part and connect the lower part to the upper part.

    摘要: A shutoff and/or control assembly for use in regulating the discharge from a metallurgical vessel includes a refractory ceramic rotor member to be coupled to a stator to be rotated relative thereto to control discharge. A drive rod has an inner end extending into the rotor member and engaging therewith such that rotation of the drive rod causes rotation of the rotor member. At least an inner end portion of the drive rod is formed of a ceramic material.
