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.

Spray nozzle device, in particular for spraying a cast strand

With a continuous casting method for producing preliminary profiles, in particular double T preliminary profiles, the downwardly flowing cooling water is pushed out of the internal curve of the preliminary profile strand () via the profile flanges and discharged using water nozzles () aligned substantially to the crossover from the bar () to the respective flange () by means of the diverting water delivered via the water nozzles (). In this way the excessive cooling caused by downwardly running cooling water is largely avoided in the internal curve of the preliminary profile strand.
