Embodiment Construction

[0029] exist figure 1 and figure 2 A side view and a top view of a work roll 2 for applying water W to a roll stand and a device 1 for removing water W are diagrammatically depicted in . The work rolls 2 are supported by backup rolls 10 . The work rolls 2 roll the rolling stock 3, which moves in the conveying direction F. The conveying direction F corresponds to the direction of the horizontal line H. FIG.

[0030] The device 1 comprises a plurality of nozzles 4 which are arranged in a water-cooled beam 11 . Water W is sprayed onto the surface of the work roll 2 through the nozzle 4 . In order to divert the sprayed water and to prevent the water from flowing unhindered onto the strip, a scraper element 5 (wiper blade) is provided which is inclined at an angle γ relative to the horizontal. On the upper surface 6 of the plate element 5 are arranged guide elements 7 , 8 (in particular welded) which enable the water W to be guided laterally from the plate element 5 in a tran...

Abstract

The invention relates to a device (1) for applying a liquid medium (W) to a roll (2), in particular to a work roll of a roll stand, and / or to a rolled material, a slab or a roughed strip (3) and / or for removing the liquid medium (W), wherein the device (1) has at least one spray nozzle (4), at least one row of spray nozzles or at least one cooling bar (11) for spraying on the medium (W) and at least one plate element (5), which is designed for collecting the medium (W), wherein the roll (2) is designed for rolling rolled material (3), wherein the rolled material, the slab or the roughed strip(3) is conveyed in a conveying direction (F). In order to allow an improved cooling effect of a roll to be cooled or an improved removal of descaling water, the invention provides that the plate element (5) has on one of its surfaces (6) at least one directing element (7, 8), which is designed for diverting medium (W) into a transverse direction (Q), which lies horizontally (H) and transversely inrelation to the conveying direction (F). The invention also relates to a method for applying a liquid medium and / or for removing the liquid medium.

Description

technical field [0001] The invention relates to a device for applying a liquid medium to a roll, in particular a work roll of a rolling stand and / or a rolling stock, a slab or a rough strip, and / or for removing a liquid medium, wherein the device has At least one nozzle, at least one nozzle row or at least one chilled beam for spraying the medium and at least one plate element configured to collect the medium, wherein the rollers are configured to roll a rolled stock, wherein the rolled stock, slab or The raw strip is conveyed in the conveying direction. The invention also relates to a method for applying and / or removing a liquid medium. Background technique [0002] The demands placed on the efficiency of work roll cooling are constantly increasing. Therefore, in order to increase the efficiency, an increasing amount of work roll cooling medium, more precisely cooling water, is used. However, for the upper work rolls, the water is restricted due to the wiper blades. As ...
