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.

Abstract: A spraying nozzle is described which is provided with an outlet opening for forming a liquid jet and with an impact surface which is arranged behind this outlet opening in the flow direction, for generating a spray fan. The impact surface is constructed as a convexly curved surface of a tongue extending from the outlet opening into the liquid jet, the impact surface also being set at a setting angle &agr; with respect to the axis of the liquid jet emerging from the outlet opening.
