Abstract
A flow rate adjusting plate for a rotary-nozzle-type molten-metal pouring unit has a shape in which one side or two sides of an octagon is or are replaced by one arc or two arcs. The arc or arcs are connected smoothly to adjacent straight sides. The plate has one hole or two holes for passing molten metal. The center of the hole corresponds to the center of the arc, and the distance between the arc and the hole is larger than the diameter of the hole.
