  • Solid cone spray nozzle
    Patent number: 7552881
    Abstract: The invention relates to a solid cone spray nozzle with a mouthpiece having an outlet chamber and an inlet opening emanating from the outlet chamber and having a smaller cross-section than the latter According to the invention an inlet opening into the outlet chamber has a smaller cross-section than the outlet chamber and downstream of the outlet chamber inlet opening is provided a web-like preatomizer element on which impacts at least partly a fluid jet following entry into the outlet chamber. Use e.g. as a two-fluid spray nozzle for spraying or atomizing low viscosity liquids for cooling purposes in billet or bloom continuous casting installations.
