Abstract
An improved roll caster tip apparatus is disclosed comprising a molten metal reservoir having a bottom plate and at least one sidewall and a nozzle tip member attached to the sidewall having a top wall, a bottom wall and a pair of converging side riser members between the top wall and the bottom wall forming a converging passageway terminating in an exit port for molten metal to flow from the reservoir to a pair of rollers. The side risers converge toward one another at the exit port by being spaced apart a shorter distance at the exit port than at the sidewall of the molten metal reservoir whereby metal flow separation along the side risers will be mitigated, thereby providing uniform metal velocity across the width of the nozzle tip member.
