Problems solved by technology
Unfortunately, the spraying devices known to those skilled in the art are not provided with easy access to said spray nozzles or easy maintenance of inspection equipment
In fact, even after the rolls have been removed from the stand, the design of the spraying station prevents any easy access to the spraying nozzles on said fixed part of the spraying station
Inspection or cleaning / replacing of injection nozzles in injection systems known to a person skilled in the art as well as general maintenance of said injection systems are therefore complex maintenance operations, time-consuming to perform and therefore economically unfavorable
Furthermore, the spraying tables known to the person skilled in the art have the further disadvantage of low stiffness resulting from their cantilevered components

Embodiment Construction
[0032] As an example, figure 1 A cross-sectional view of a rolling mill of the 20-roll type comprising spraying devices 11, 11', 12, 12' according to the prior art is shown. The work rolls 3, 3' in contact with the strip 2 to be rolled are supported by two intermediate backup rolls 4, 4' which are themselves supported by three intermediate backup rolls 5, 5a, 5', 5'a support, the three intermediate support rolls 5, 5a, 5', 5'a themselves are supported by four support roll columns 6, 6', each support roll column is alternately mounted on a single support A plurality of support rollers on the shaft and a mounting plate 7 by which a single support shaft is supported.
[0033] figure 2 shows the use of figure 1 A cross-sectional view of an exemplary embodiment of a rolling mill of the 20-roll type comprising an injection device according to the invention, marked with the same symbols as used in . and figure 1 Instead, the upper spraying device 11' and the lower spraying devi...

The device e.g. lower spray device (11), has elongated shaped fixed spray tables (11A, 11A, 12A, 12A) configured to be rigidly connected to a set of mounting plates (7) in a row of bearing rolls (6, 6) of a roll stand. The table includes a fluid dispensing network for routing a spray fluid toward nozzles (113) for lubricating and cooling a metal strip (2) and / or air gap of the roll stand. A connector connects the fluid-dispensing network to a fluid supply network. An attachment unit rigidly connects the tables to the mounting plates. Independent claims are also included for the following: (1) a multi-cylinder roll stand (2) a method for removing or inserting a spray device from / into a roll stand.
Description
technical field [0001] The invention relates to a spraying device suitable for a plant for rolling a metal strip in motion according to the preamble of claim 1 and to a spraying device according to the preamble of claim 13 for combining spraying and Guide removal from / insertion of injection and guides into the roll stand. [0002] In particular, the invention relates to the lubrication and cooling of the metal strip and the elements associated with the cold rolling of said strip moving continuously or reversibly in at least one rolling stand or rolling mill in a rolling plant . In particular, said elements relate to a set of stacked rolls having parallel longitudinal axes disposed approximately in at least a single plane perpendicular to the direction of travel of the belt. The longitudinal axis of one of the rolls is defined as the instantaneous axis of rotation parallel to the generatrix of the roll and passing through the center of mass of the roll. More particularly, th...
