The nozzle the bar in order to introduce the melting metal into ingot die because of continual metal casting armament

摘要

The invention concerns a nozzle (1) for introducing molten metal into an ingot mould for continuous metal casting and comprising a first tubular part (2) whereof one end is designed to be connected to a vessel containing said molten metal and the other end emerges into a second hollow part (4) of elongate shape of which at least one portion of the internal space (3) is oriented substantially perpendicular to the first tubular part (2), said hollow part (4) comprising an orifice (5 and 6) at each of its ends and a bar (19 and 27,29) provided with perforations (21) being arranged in the internal space (3) of said hollow part (4). The invention is characterised in that the orifices (5 and 6) of said hollow part (4) are closed above said bar (19, 27 and 29).
