摘要： A metal delivery system for a casting system includes a spout having a spout passageway extending through the spout with an elongated slot as a bottom orifice. A bottom control pin is positionable within the spout and is movable between a closed position and an open position. In certain aspects, in the closed position, the bottom control pin engages a portion of a surface of the passageway proximate to the bottom orifice.
