Abstract
The invention relates to a spray nozzle, particularly a high pressure nozzle, for descaling steel products, having a mouthpiece, which is provided with a discharge opening and a discharge chamber, which tapers towards the discharge opening. According to the invention the discharge opening spans a curved surface and a surface surrounding the discharge opening boundary at each point of said boundary strikes the discharge opening boundary at an angle between 65 and 95°, particularly 90° to the median longitudinal axis. Use e.g. for descaling nozzles.
