ABSTRACT:
The invention relates to a refractory submerged pouring nozzle for the continuous casting of molten metals, especially molten steel, in a mould for thin slabs. The submerged pouring nozzle 2 is covered by a bottom plate 13 on its lower end face and has two opposing outflow orifices 11. While the edge of the bottom 13 forms a breakaway edge 11' for the molten metal, there adjoins the remaining edge of the especially archway-like outflow orifice 11 a roof-shaped guide element 15, the sideparts 15'0 of which have free edges 15" projecting from the outer edge of the upper part 15" of the guide element 15 and extending obliquely downwards to the lower breakaway edge 11'.
