Problems solved by technology

This results in a smaller nozzle cross-section for a given quantity of water to be applied and thus an increased risk of clogging
If the intermediate space between the two guide rollers is not completely covered by a spray jet, this can lead to reheating of the strand shell of the continuously cast product in the areas not covered by the spray jet, which can result in cracks in shell

Embodiment Construction

[0061] figure 1 The perspective view of FIG. 2 shows a spray nozzle 10 according to the invention with an integral spray body housing 12 . A discharge cone 14 can be seen in one end face of the ejector housing 12, which is connected to a figure 1 Invisible, oval discharge hole. The discharge cone 14 has a substantially likewise elliptical cross-sectional shape, wherein this figure 1 It is not easy to see in the view of , and the side end of the discharge cone is also cut off by the chamfer 16 at the transition from the end face to the side of the nozzle housing 12 .

[0062] The spray body housing 12 is generally cylindrical and has a circumferential flange 18 at its rear end, the end for connection to a fluid line. The side of the flange 18 is equipped with an inverted flat portion 20, wherein figure 1 Only one flattened portion is seen in the view of , but it covers the opposite identical flattened portion.

Abstract

The invention relates to a solid cone spray nozzle, particularly for atomizing low viscosity liquids for cooling purposes in bloom continuous casting installations, with a mouthpiece having an outlet chamber and an outlet opening emanating from the outlet chamber and having a smaller cross-section than the latter, wherein an inlet opening into the outlet chamber has a smaller cross-section than the outlet chamber and downstream of the outlet chamber inlet opening is provided a web-like preatomizer element on which impacts at least partly a fluid jet following entry into the outlet chamber, wherein the inlet opening is located in a baffle which is mounted in a mouthpiece housing, the web-like preatomizer element is provided on a U-stirrup which is inserted in the mouthpiece housing, the baffle and the U-stirrup are located an integral embedded part.

Description

technical field [0001] The invention relates to a full-cone nozzle, in particular for atomizing low-viscosity liquids for cooling in a billet caster or bloom caster, the spray nozzle having a spray body, the spray body There is an outlet chamber and an outlet from the outlet chamber, which has a smaller cross-section than the outlet chamber. Background technique [0002] A two-component full-cone nozzle is known from European patent document EP 1243343 B1, which is used for cooling in continuous casting machines. A spout body of this nozzle has an outlet chamber with an outlet opening emanating from the outlet chamber, which has a smaller cross-section than the outlet chamber. A vortex insert is arranged in the discharge chamber formed in the discharge body by the opening, by means of which the gas-liquid mixture is placed in a swirl before reaching the discharge orifice, whereby it emerges conically under pressure from the discharge excreted from the body. The eddy curre...
