が節減される効果がある．DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a water cooling device for strip used for hot rolling or heat treatment of strip. [Prior Art] Figure 2 is an explanatory diagram showing the conventional technology. The strip (width a) 4 moves on rollers 8 in a direction perpendicular to the plane of the paper, and cooling water forms a laminar flow from the nozzle 3 of the header (width b) 9 and falls onto the strip, cooling it. do. Since the width a of the strip varies depending on the product dimensions, the effective width b of the header (distance between the outermost nozzles) is determined corresponding to the maximum value of a. [The problem that the invention aims to solve! ] However, since the conventional device is configured as described above, ineffective cooling water is discharged by a length corresponding to ba of the header. The object of the present invention is to solve the above problems and to propose a strip water cooling device that can effectively use cooling water. [Means for Solving the Problems] The present invention relates to a strip water cooling device that discharges cooling water at an upper part of a strip conveyance path, in which a plurality of nozzles are arranged in the discharge header. ,
A strip water cooling device that allows one or more parts of the header to pivot. [Function] The strip water cooling device according to the present invention has one of the headers.
By making the above parts pivotable up and down or left and right, the projection surface for that strip is always within the full width of the strip! l Adjust. [Example] Figure 1 is an explanatory diagram showing an example of the present invention. The cooling water reaches the cheese 6 via the conduit 5, and the header 1 via the flexible tube 7. The header 1 can rotate up and down around the fulcrum 2. The angle with respect to this horizontal plane is α, and the effective length of the plurality of nozzles 3 attached to the header is the distance from the fulcrum 2 to the outermost nozzle.
If the width of the strip 4 running on the roller 8 is d, then it is possible to use the cooling water effectively by setting the angle α so that α=cos-'(d/2c). Become. Further, the angle a is changed after the leading strip passes in accordance with the width of the trailing strip. The settings are made by a computer that controls the strip's water cooling system. In the present invention, a laminar flow type nozzle has been described, but the present invention can also be applied to a spray type nozzle, and the rotating surface may be a horizontal plane. Additionally, this type of strip water cooling equipment can be used for both rolling and heat treatment. [Effects of the Invention] As described above, in the present invention, since the header of the cooling water can be rotated, the usage of cooling water is significantly reduced, and the cooling water consumption rate is reduced.
