Abstract

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.
