Abstract
A long-range nozzle, used in particular for cooling the strand and/or the supporting and guiding rollers of a continuous casting plant by means of liquid jets or liquid and gas jets is provided with a plurality of parallel nozzle channels arranged side by side in one plane. All of the nozzle channels are connected with each other in the area of the mouth of the nozzle by means of a transverse channel that is open in the spraying direction. The transverse channel has two parallel limiting areas. The hydraulic diameter of each channel is 1.5 to 4 mm. The ratio of the hydraulic diameter of each channel to the distance between the two channel axes is 0.7 to 0.9. With the nozzle of the present invention a long range for the spray jet and a close bundling of the spray jet are achieved.
