An improved molten metal feed system is provided for high speed continuous casting. The feed system includes a distributor box (28) having an insulative lining (50) which supports an internal flow distributor board (60). The flow distributor board (60) includes a plurality of openings spaced apart along the width of the board (60). The presence of the flow distributor board (60) effectively separates the box (28) into lower (62) and upper (64) sections and restricts the flow of liquid metal (14) through the board (60) and thus, forces entering liquid metal (14) to fill the entire width of the distributor box (28) below the distributor board (60) once the lower section (62) of the distributor box (28) is filled, the metal flows through the openings in the board (60) into the upper section (64) of the distributor box (28) and into the feed tip nozzle (30).
