Abstract
Disclosed is an improved casting tip for a nozzle of a continuous caster, the tip designed for transferring molten metal from a molten metal reservoir to a continuously advancing mold as formed, for example, by twin belts, rolls or block casters for casting molten metal into solid form. The casting tip is comprised of a top wall, a bottom wall oppositely disposed from top wall, a first side wall, and a second side wall oppositely disposed from the first side wall, the first and second side walls joined to the top and bottom walls to form a passage therebetween having an entrance and an exit. The passage has a top wall inside surface having a first portion that first converges towards the bottom wall starting at the entrance and has a second portion that diverges from the bottom wall to the exit, the top wall first portion having a length less than the top wall second portion length. Further, the passage has a bottom wall inside surface having a first portion that first converges towards the top wall starting at the entrance and has a second portion that diverges from the top wall to the exit, the bottom wall first portion having a length less than the bottom wall second portion len…
