摘要：
A tube for pouring liquid metal has a pouring channel with a pouring axis. The tube has a downstream part with a pouring channel with an outlet diameter, and a flared upstream part with a length known as the threshold distance. The threshold distance is greater than four times the outlet diameter. The upstream part is flared and configured so that its upper end has a convex overall shape in the axial direction. The upstream part is included within a first volume corresponding to the complementary part of an axisymmetric frustoconical volume having as its axis the pouring axis. The generatrix of the volume forms an angle greater than 5 degrees with the pouring axis. The upstream part is included within a second volume, delimited by a surface of revolution generated by an isosceles trapezium revolving about the pouring axis.
