Title: Fluted,-stepped, pour nozzle

Abstract: Flaring, splashing and spitting of the molten metal flow stream issuing from a flow control nozzle of the type forming the collector nozzle of a sliding plate valve is prevented by forming the flow passage through the nozzle with a flow-impeding constriction intermediate the ends thereof. The passage is also provided with a duct section downstream of the constriction and includes means for preventing recirculatory currents in the flow stream from entering and passing the constriction.
