摘要： A continuous casting plant for slabs, comprising a water-cooled mould from which the strand is continuously extracted, a supporting and guiding means having rollers for guiding the strand between them, and a cooling device having nozzles for spraying a coolant, in particular water, onto the strand and the rollers, has a part of the cooling device formed by flat jet nozzles arranged parallel to the surface of the strand. The longitudinal axes of the nozzles are parallel to the axes of the rollers, and two flat jet nozzles are arranged between neighboring rollers. Advantageously, the flat jet nozzles are arranged within the area defined by the slab edges of the slab sizes to be cast in the plant, and advantageously they are arranged opposite and toward each other. Furthermore, the flat jet nozzles can have nozzle openings in opposite directions, each opening pointing toward the slab edges. Advantageously, the flat jet nozzles are displaceable in the direction of the roller axes and are thus adjustable to various slab widths.

摘要： 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.
