Abstract
The invention relates to a nozzle for introducing a liquid metal into a mold for continuous casting of metals, of the type comprising a tubular first part, one end of which is intended to be connected to a receptacle enclosing said liquid metal, and the other end of which opens into a hollow second part in which at least one portion of the internal space is oriented substantially perpendicularly to said tubular first part, said portion comprising at each of its ends at least one orifice intended to emerge into the casting space of said mold, which comprises an obstacle placed in the path of the liquid metal inside said tubular first part or in its extension, said obstacle consisting of at least one perforated component intended to divert the metal from its preferential trajectory inside the nozzle.
