Roll caster apparatus

Abstract From the Canadian patent

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 …
