Problems solved by technology

That is, the diaphragm cannot be continuously adjusted during the rolling operation without interrupting the water flow during the
Furthermore, the width adjustability of the water cooling cannot be achieved continuously or always finely enough due to the limited number of slots, so that the rolling stock may not be cooled optimally

Embodiment Construction

[0053] Figures 1 to 3 An embodiment of a spray beam 1 according to the invention is shown. here, figure 1 A horizontal cross-section through the spray beam 1 is shown. The spray beam 1 consists essentially of a cylindrical housing 2 which is hollow (hollow cylinder) and which can be supplied or filled with water. This feeding is preferably effected via one or more holes at the left or right end (in this case at the right end) of the hollow cylinder 2 . However, these holes can likewise be provided at other locations of the housing, for example in the side surfaces. At least one discharge opening 3 is provided in the housing 2 . In this exemplary case it is two rows each with equally spaced discharge holes 3, wherein these rows are shifted relative to each other so that the number of discharge holes 3 in the longitudinal direction A of the housing 2 is compared to only one Row 3 doubles. Other arrangements of the outlet openings 3 are also possible, depending on the resp...

Abstract

The invention relates to a spray bar, a path and a method for applying a medium onto a product, in particular in hot strip mills, CSP facilities or other strip processing lines. The spray bar (1) used therefor comprises a housing (2) with outlet openings (3) from which the medium can be applied onto the product. To this end, the outlet openings (3) can be covered in a sealing manner or can be released by a pivotable cover (4) which is formed by at least one segment of a hollow cylinder and which is arranged on at least one of the two ends of the housing. In this way, no medium is conducted onto edge regions which are not to be treated and, simultaneously, an accurate adjustability of the treatment is ensured.

Description

technical field [0001] The present invention relates to the field of the application of a medium onto a product, in particular the cooling of metal strips, and further in particular in hot strip mills (Warmbandstraβe), CSP plants or other strip processing lines (Bandprozesslinien) middle. Here, the medium is applied to the product via spray beams. Such a spray beam has a housing with discharge openings from which the medium is delivered to the product. Devices for avoiding edge overspray or for so-called edge masking are used to improve the quality of rolled or cast products. Background technique [0002] Various devices are known from the prior art, which apply a medium, such as cooling water, to the product, such as a strip, in different forms and in different ways, and at the same time are designed to avoid edge overspray, which would reduce the produced product. The quality of the strip (eg due to the formation of cracks). [0003] Patent application EP 1 060 805 A2 ...
