Abstract

A device and a method for applying a liquid medium to a roll, and/or to a rolled material, a slab or a roughed strip and/or for removing the liquid medium, wherein the device has at least one spray nozzle, at least one row of spray nozzles or at least one cooling bar for spraying on the medium and at least one plate element, which is designed for collecting the medium. The roll is designed for rolling rolled material, wherein the rolled material, the slab or the roughed strip is conveyed in a conveying direction. In order to allow an improved cooling effect of a roll to be cooled or an improved removal of descaling water, the plate element has on one of its surfaces at least one directing element, which is designed for diverting medium into a transverse direction, which lies horizontally and transversely in relation to the conveying direction.

First claim

The invention claimed is:

1. A device for applying a liquid medium to a roll, a rolled material, a slab, or a rough strip conveyed in a conveying direction, and for removing the liquid medium, the device comprising: at least one spray nozzle for spraying the medium; at least one plate element configured for collecting the medium; and at least one guide element arranged on one surface of the plate element, the at least one guide element being configured to deflect the medium in a transverse direction that lies horizontal and transverse to the conveying direction, wherein the at least one guide element is planar and is disposed on the plate element at an angle in a plane of the plate element between 5° and 80° in relation to the transverse direction or the at least one guide element is configured so as to be curved.

2. The device according to claim 1 , wherein the at least one spray nozzle is arranged to deliver the medium onto the roll in a predefined central direction, wherein a tangent that points in a circumferential direction of the roll, at a location where the central direction meets the roll, is at an angle to the central direction that is larger than 90°.

3. The device according to claim 1 , wherein the at least one spray nozzle includes a plurality of spray nozzles disposed vertically on top of one another, wherein the plate element is disposed between two of or below said spray nozzles.

4. The device according to claim 3 , wherein the at least one guide element is curved and includes a plurality of guide elements disposed on the plate element, wherein the angle of said guide elements decreases as a spacing from the roll, from the cooling bar, or from a descaling bar increases.

5. The device according to claim 1 , wherein the at least one guide element is disposed so as to be perpendicular, inclined or twisted about a longitudinal axis of the guide element in a direction of the plate element.

6. The device according to claim 1 , wherein the at least one guide element includes a plurality of guide elements disposed on the plate element, wherein said guide elements are disposed on the plate element so as to be symmetrical or asymmetrical to a vertically running central plane.

7. The device according to claim 1 , wherein the at least one guide element includes a plurality of guide elements disposed on the plate element, wherein said guide elements are dissimilar in terms of vertical height.

8. The device according to claim 1 , further comprising means for transverse spraying disposed on the plate element.

9. The device according to claim 1 , wherein the plate element is arranged so as to be laterally spaced from a roll stand by more than 50 mm.

10. The device according to claim 1 , wherein the plate element is disposed at an angle between 1° and 45° to horizontal.

11. The device according to claim 1 , wherein the at least one nozzle includes at least one row of nozzles.

12. The device according to claim 1 , wherein the at least one nozzle includes at least one cooling bar.

13. A method for applying a liquid medium to a roll, a rolled material, a slab, or a rough strip conveyed in a conveying direction, and for removing the liquid medium, the method comprising the steps of: spraying the medium onto the roll with at least one spray nozzle; and collecting the medium with at least one plate element, wherein at least one guide element is arranged on a surface of the plate element, the at least one guide element being configured to deflect the medium in a transverse direction that lies horizontal and transverse to the conveying direction, wherein the flow movement of the applied liquid medium diverts the liquid medium to the transverse direction by way of the at least one guide element, wherein the at least one guide element is planar and is disposed on the plate element at an angle in the plane of the plate element between 5° and 80° relative to the transverse direction, or the at least one guide element is configured to be curved.
