Abstract
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 () comprising in its upper part a distributing member, arranged substantially at the intake of said conduit and including a dome () 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 () into an inner zone (). The dome () 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 () and penetrating into the ingot mould () through a first orifice () at the lower base of said conduit () and the other jet (C) flowing into an outer zone () and penetrating into the ingot mould () through lateral orifices () located in the vertical wall of said conduit ().
