Abstract

An improved roll caster tip apparatus is disclosed comprising a molten metal reservoir (2) having a bottom plate (6) and at least one sidewall (16,18) and a nozzle tip membr (32) attached to the sidewall (16) having a top wall (36), a bottom wall (40) and a pair of converging side riser member (44,46) between the top wall (36) and the bottom wall (40) forming a converging passageway (50) terminating in an exit port (52) for molten metal to flow from the reservoir (2) to a pair of rollers (60, 62). The side risers (44,46) converge toward one another at the exit port (52) by being spaced apart a shorter distance at the exit port (52) than at the sidewall (16) of the molten metal reservoir (2) whereby metal flow separation along the side risers (44,46) will be miti­ gated, thereby providing uniform metal viscosity across the width of the nozzle tip member (32). Further disclosed is the including of a streamlined spacer member (70) between top (36) and bottom (40) walls of the tip member (32); preselect­ ing the dimensions of the spacer member (70) and top (36) and bottom (40) walls to provide near Hele-Shaw flow conditions; and providing a baffle member (24) in the reservoir (2).
