A two-substance nozzle for spraying a liquid-gas mixture, including a nozzle housing including at least one liquid inlet leading into a mixing chamber and at least one gas inlet leading into the mixing chamber, a swirl insert, an outlet chamber between the swirl insert and an outlet opening on the downstream end of the outlet chamber, wherein a restrictor is provided on the downstream end of the mixing chamber and an intermediate chamber is provided between the restrictor and the swirl insert.

Two-substance nozzle and method for spraying a liquid-gas mixture

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.

Solid cone spray nozzle

The invention relates to a cone nozzle with a nozzle body having a swirl chamber (), an inlet hole () arranged in a side wall of the swirl chamber () and an outlet hole () arranged in a first end wall of the swirl chamber (). In accordance with the invention a rotation-symmetrical projection () or a rotation-symmetrical recess is arranged on a second end wall of the swirl chamber opposite the first end wall and at least two blind holes () are arranged in the first end wall adjacent to the outlet hole (). Use for secondary cooling of continuous billet casting plant, for example.
