• said casting spout having downstream from the tubular portion a portion that is conically widened down from the round tubular shaft portion in a first vertical plane only, and being conically narrowed in a plane extending at right angles to said first plane;
• and
• said casting spout being provided with a second still lower portion underneath the conically widened and narrowed portions and having a rectangular cross section which extends over its height for a lengthwise rectangular cross section and terminates in an outflow area at said lower end at a length-to-width ratio from 20:1 to 80:1 and a wall thickness of the second still lower portion of not more than about 10 mm.
