An improved molten metal feed system is provided for high speed, continuous casting of metals and alloys. The feed system includes a distributor box having an insulative lining which supports an internal flow distributor board. The flow distributor board includes a plurality of openings of various sizes and shapes spaced apart along the width of the board. The presence of the flow distributor board effectively separates the box into lower and upper sections and restricts the flow of liquid metal through the board and thus, forces entering liquid metal to fill the entire width of the distributor box below the flow distributor board. In addition, the liquid metal is stabilized across the width of the distributor box resulting in a balanced temperature gradient. Once the lower section of the distributor box is filled, the metal flows through the openings in the board into the upper section of the distributor box and into the feed tip nozzle. Flow dividers are also provided which are adapted to be positioned along the width of the distributor box. A baffleless feed tip nozzle is coupled to the distributor box. An adjustment mechanism is coupled to the feed tip nozzle which allows adjustment of the size of the feed tip opening.
