Abstract: Spray nozzle device for spraying a cast strand or similar metallurgical products with a misty air/water mixture for uniformly cooling the cast strand. The air/water mixture is produced in a mixing chamber which acts as a diffusor and includes an air inlet, a water inlet, and a nozzle outlet approximately in alignment with the air inlet. The air inlet is arranged in an air inlet nozzle, the tip of which protrudes into an upper region of the mixing chamber and preferably has air outlet holes oriented perpendicular to a longitudinal axis of the mixing chamber. Water enters near the tip through at least one water outlet hole oriented perpendicular to the longitudinal axis and placed such that the water jet exiting the water outlet hole flows past the air outlet holes. The air flow or air pressure and the water flow or water pressure do not influence each other.

Abstract: The invention relates to a spray nozzle device for spraying a cast strand or similar metallurgical products with a misty air/water mixture in the form of a mist for uniformly cooling the cast strand. The air/water mixture is produced in a mixing chamber (2) of the spraying device. Said mixing chamber acts as a diffusor and is provided with an air inlet (3), a water inlet (4), and a nozzle outlet (5) oriented approximately in alignment with the air inlet. The air inlet (3) is arranged in an air inlet nozzle (6), the tip (7) of which protrudes into the upper region of the mixing chamber and preferably has a plurality of air outlet holes (9) there, which air outlet holes are oriented perpendicular to the longitudinal axis of the mixing chamber; Water enters near the tip (7) through at least one water outlet hole (11), which is oriented perpendicular to the longitudinal axis and which is placed in such a way that the water jet exiting the water outlet hole flows past the air outlet holes (9). The spray nozzle according to the invention is characterized in that the air flow or the air pressure and the water flow or the water pressure do not influence each other.
