Abstract
The invention concerns a pouring spout for the transfer of a molten metal from a tundish into a continuous-casting mold. The pouring spout includes a body comprising a tubular part defining an essentially vertical pouring channel and an essentially horizontal part defining a distribution channel. The tubular and horizontal parts are assembled together, notably by screwing. The vertical pouring channel has an upper end adapted to connect with a tundish and a lower end emptying into the distribution channel. The distribution channel includes at least two outlets adapted to distribute molten metal into the mold. An obstacle is located between the two channels and together with the lower part of the tubular part retains the molten metal in the pouring channel until transfer to the distribution channel.
