Disclosed are process and apparatus for use in the direct casting of metal strip from molten metal deposited on a moving chill surface from a tundish having a floor, opposed upwardly extending sidewalls, an end wall, an open outlet opposite the end wall with the open outlet extending substantially the full width of the tundish between the sidewalls, and an inlet for providing a flow of molten metal into the tundish from a source of molten metal. Flow diverters within the tundish divide the flow of molten metal into a plurality of separate streams and divert one of the streams in the direction of each sidewall and for recombining the diverted streams into a composite stream flowing toward the outlet. Flow diffusers diffuse the molten metal flowing through the tundish to provide molten metal of substantially uniform temperature across the width of the tundish at the outlet.

Process for direct casting of molten metal to form strip by solidification of molten metal on a moving chill surface using a vessel having a floor, spaced sidewalls, an inlet and an outlet extending between the sidewalls, comprising: positioning the vessel with the outlet adjacent the chill surface; providing a source of molten metal to be cast; withdrawing an inlet stream of molten metal from the source and flowing the inlet stream into the vessel through the inlet; dividing the inlet stream into a first stream and a second stream; diverting the first stream in a direction toward one sidewall of the vessel; diverting the second stream in a direction toward the other sidewall of the vessel; diffusing the first stream and the second stream; intermixing the diffused streams to form a composite stream extending throughout the width of the outlet; and flowing the composite stream in a direction toward the outlet. A tundish for use in direct casting of molten metal on a chill surface of predetermined width comprising: means for providing a source of molten metal; means for withdrawing an inlet stream of molten metal from the source and for dividing the inlet stream into a first divided stream and a second divided stream; means for oppositely diverging the first divided stream and the second divided stream; means for diffusing the first divided stream and the second divided stream; means for combining the diffused streams to form a composite stream; and means for flowing the composite stream in a direction toward the chill surface.
