  • Casting nozzle
    Patent number: 11446734
    Abstract: A casting nozzle for use in the casting of molten metal produces a stable flow pattern having an elongated section in the horizontal plane. The bore cross-sectional area contains, from entry to exit, at least two significant section area reductions to reduce turbulence, realign streamlines and affect flow distribution inside the nozzle. The bore cross-section has a local minimum value in a contraction section located between the entry section and an expansion section. Bore cross-sectional area decreases from the expansion section to the lower end of the nozzle. The two significant cross-sectional area reductions cooperate with other structures within the bore to stabilize flow.
