<p>The invention relates to a nozzle for guiding molten metal flowing from a vessel into a mould. The nozzle comprises a conduit which is elongate along an axis which is orientated vertically during use. The nozzle has at least one upper inlet (12) and towards its lower end two spaced apart baffles (19,20), the respective outer walls of the baffles partly defining two lower outlets (13,14) and the respective inner walls of the baffles defining at least part of at least one outlet flow passage (15) there between. Each baffle inner wall is at least partly concavely curved and arranged so that there is converging flow from said outlet flow passage or passages.</p> |
