Abstract
An improved roll caster tip apparatus is disclosed capable of providing metal flow therein with a near Hele-Shaw profile comprising a molten metal reservoir having a bottom plate and at least one sidewall and a nozzle tip member attached to the sidewall and terminating in an exit port spaced from the sidewall, the nozzle tip member comprising a top wall, a bottom wall, a pair of side riser members between the top wall and the bottom wall to form a passageway in cooperation with the top and bottom walls; and at least one spacer member between the top wall and the bottom wall spaced from the side risers to provide support for the top wall and bottom wall and having a chord length extending from the leading edge of the spcer facing the reservoir to the trailing edge of the spacer facing the exit port, the chord length of the spacer and the distance between the top wall and bottom wall of the nozzle tip being preselected with respect to the velocity and viscosity of the molten metal flowing through the nozzle tip to provide at least near Hele-Shaw flow conditions characterized by a reduced Reynolds number of not more than 10.
