Problems solved by technology
This solution thus prevents evacuation of the chilled beams, but is very expensive
Furthermore, the outlet tubing can only be switched simply (fully open or fully closed), but no continuous adjustment is possible

Embodiment Construction
[0035] according to Figures 1 to 3 , the flat rolling stock 1 should be cooled in the cooling section. The flat rolling stock 1 is made of metal, wherein the term "metal" within the meaning of the present invention is also intended to include common and widely used alloys. For example, the flat rolling stock 1 can consist of steel or aluminum. The flat rolling stock 1 can be, for example, a strip or a thick plate. The cooling section can be arranged, for example, on the discharge side of a multi-stand finishing train.
[0036] The flat rolling stock 1 is conveyed through the cooling section along the conveying direction x. For this purpose, the cooling section has a conveying section on which the flat rolling stock 1 is conveyed. For reasons of clarity, only one of the conveyor rollers 2 of the conveyor section is shown and this is only figure 2 shown in .
[0037]At least one cooling beam 3 is present for cooling the flat rolling stock 1 . The chilled beam 3 is arran...

Abstract
The invention relates to a flat rolled material (1) made of metal, and the flat rolled material (1) is conveyed on a conveying path in a transport direction (x). A device for cooling the flat rolled material (1) by means of a liquid coolant (5) has at least one cooling bar (3), which is arranged above the conveying path and to which the liquid coolant (5) is fed via a supply line (4). The cooling bar (3) extends substantially perpendicularly to the transport direction (x) and has a plurality of outlet tubes (6), which in turn each have an inlet opening (7) and an outlet opening (8). The liquid coolant (5) enters the outlet tubes (6) from the cooling bar (3) via the respective inlet openings (7) and exits the outlet tubes (6) via the respective outlet openings (8). Each outlet tube (6) has, in the flow direction of the liquid coolant (5), an initial portion (9), which proceeds from the inlet opening (7) and extends upward, a middle portion (10), which adjoins the initial portion, and an end portion (11), which adjoins the middle portion, extends downward and extends to the output opening (8). The middle portion (10) therefore contains a vertex (12), at which the coolant (5) flowing through the outlet tube (6) in question reaches a highest point. The outlet openings (8) are located above the cooling bar (3). A height distance (h1) of the inlet opening (7) from the vertex (12) is at least twice as large, in particular at least three times as large, as a height distance (h2) of the outlet opening (8) from the vertex (12).
Description
technical field [0001] The invention relates to a device for cooling a flat rolling stock made of metal with a liquid coolant, [0002] - wherein the flat rolling stock is conveyed along the conveying direction on the conveying section, [0003] - wherein the device has at least one cooling beam arranged above the conveying section, the liquid coolant is fed to the cooling beam via a supply line, [0004] - wherein said chilled beam extends substantially transversely to said conveying direction and has a plurality of outlet tubules, [0005] - wherein said outlet tubules respectively have an inflow opening and an outflow opening, [0006] - wherein the liquid coolant enters from the chilled beam via a corresponding inflow opening into a corresponding outlet small tube and exits from the corresponding outlet tube via a corresponding outflow opening, [0007] - wherein the respective outlet small tube has, viewed in the flow direction of the liquid coolant, an upwardly extend...
