The invention concerns a nozzle mainly consisting, when viewed in vertical position and in a forward movement of the liquid steel from the top downwards, of a vertical conduit ( 5 ) comprising in its upper part a distributing member, arranged substantially at the intake of said conduit and including a dome ( 6 ) for deflecting the metal penetrating into the nozzle, which is also provided with means for injecting a gaseous, liquid or solid finely divided material beneath said dome ( 6 ) into an inner zone ( 11 ). The dome ( 6 ) of said distributing member is provided with means for separating liquid steel into two jets (B, C), one jet (B) flowing into the inner zone ( 11 ) and penetrating into the ingot mould ( 1 ) through a first orifice ( 9 ) at the lower base of said conduit ( 5 ) and the other jet (C) flowing into an outer zone ( 12 ) and penetrating into the ingot mould ( 1 ) through lateral orifices ( 8 ) located in the vertical wall of said conduit ( 5 ). |
