This cooling process also heat treats the strip, enhancing its overall mechanical properties.
[0003] When the water spraying mechanism of the prior art sprays water on the slab, the water spraying may be uneven, thereby affecting the cooling of the slab. Utility Model Content

[0014] Optionally, a flow-pushing component is provided inside the water tank for pushing the water inside the water tank to move close to the first water outlet pipe and the second water outlet pipe.
[0015] By adopting the above technical solution, during the water spraying process, the flow-pushing component can accelerate the process of water inside the water tank flowing into the first drain pipe and the second drain pipe, thereby reducing the phenomenon that water inside the water tank has difficulty flowing into the first drain pipe and the second drain pipe.
[0016] Optionally, the flow-pushing component includes flow-pushing blades located inside the water tank.
[0017] By adopting the above technical solution, after the water inlet pipe guides the water into the water tank, the push-flow fan blades drive the water inside the water tank to flow close to the inner wall of the water tank, thereby accelerating the process of the water inside the water tank flowing into the first drain pipe and the second drain pipe.

[0029] The following is combined with Figure 1 -Attached Figure 2 This application is described in further detail.
[0030] The present application discloses a laminar cooling system. Figure 1 and Figure 2 The invention comprises a water tank 1, wherein a water inlet pipe 11 is penetrated and fixedly connected to the upper side of one side wall of the water tank 1. A plurality of first water outlet pipes 12 are connected to the two opposite side walls of the water tank 1 not connected to the water inlet pipe 11. The plurality of first water outlet pipes 12 connected to each side wall of the water tank 1 are all located in the same horizontal plane and are parallel to each other and spaced apart.
[0031] Each first water outlet pipe 12 is provided with a first drain pipe 2 at one end away from the side wall of the connected water storage tank 1, and a first rotary joint 21 is provided between each first drain pipe 2 and the adjacent first water outlet pipe 12 for connecting the first drain pipe 2 and the first water outlet pipe 12. Each first drain pipe 2 is configured to be L-shaped, and the end of each first drain pipe 2 away from the connected first rotary joint 21 is arranged vertically downward.
[0032] The multiple first drain pipes 2 are connected to the same driving assembly 3 , and the driving assembly 3 is used to drive the multiple first drain pipes 2 to rotate.
[0033] When water spraying is required, water is injected into the water tank 1 through the water inlet pipe 11. At the same time, the multiple first drainage pipes 2 connected are driven to rotate by the driving component 3, so that the lower ends of the multiple first drainage pipes 2 can swing to spray water evenly to the slab on the lower side, making the cooling of the slab more uniform.
[0034] The drive assembly 3 includes a drive gear 31 fixedly mounted on the outside of each first drain pipe 2. A common drive rack 32 is engaged on the upper sides of the multiple drive gears 31 fixedly connected to the same side of the water tank 1. The drive rack 32 is arranged horizontally. The two drive racks 32 are fixedly connected to the same drive plate 33 at the same end. The drive plate 33 is arranged parallel to the adjacent side wall of the water tank 1. A drive cylinder 34 is provided between the drive plate 33 and the opposite side wall of the water tank 1. The drive cylinder 34 is arranged horizontally, and the cylinder body of the drive cylinder 34 is fixedly connected to the adjacent side wall of the water tank 1. The piston rod of the drive cylinder 34 is fixedly connected to the drive plate 33.
[0035] During the water spraying process, the drive cylinder 34 is activated, which drives the drive plate 33 to move. The drive plate 33, in turn, drives the two connected drive racks 32 to move. The drive racks 32, in turn, rotate the connected drive gears 31. The drive gears 31, in turn, rotate the connected first drain pipes 2, thereby achieving rotation of the multiple first drain pipes 2 through the drive assembly 3.
[0036] A second water outlet pipe 13 is provided on the underside of each first water outlet pipe 12, arranged parallel to the adjacent first water outlet pipe 12. Each second water outlet pipe 13 is connected to the adjacent water tank 1. A second drain pipe 4 is provided at the end of each second water outlet pipe 13 away from the side wall of the connected water tank 1. Each second water outlet pipe 13 is connected to the adjacent second drain pipe 4 via a second rotary joint 41.
[0037] Each second drain pipe 4 is configured in an L-shape, and the lower end of each second drain pipe 4 is vertically downward, and the lower end of each second drain pipe 4 is staggered with the lower end of the adjacent first drain pipe 2. Each second drain pipe 4 is connected to the drive assembly 3 and can rotate under the drive assembly 3.
[0038] By providing a plurality of second drainage pipes 4 and each second drainage pipe 4 being connected to the driving assembly 3 , a more sufficient water spraying process can be achieved on the lower slab, making the slab cooling process more uniform.
[0039] A driven gear 35 is fixedly sleeved on the outside of each second drain pipe 4 , and one side of each driven gear 35 is meshed with the adjacent driving gear 31 .
[0040] In the process of driving the driving cylinder 34 to drive the driving plate 33 to move, the driving plate 33 drives the driving rack 32 to move, and the driving rack 32 drives the driving gear 31 to rotate during the movement. Each driving gear 31 drives the connected driven gear 35 to rotate during the rotation, so that the adjacent first drain pipe 2 and the second drain pipe 4 rotate in opposite directions, thereby realizing the process of uniform spray cooling of the slab on the lower side of the water tank 1.
[0041] A flow-pushing assembly 5 is also provided inside the water tank 1 , which is connected to the driving assembly 3 and can guide the water inside the water tank 1 to the first water outlet pipe 12 and the second water outlet pipe 13 under the drive of the driving assembly 3 .
[0042] By providing the flow-pushing component 5, the process of water flowing from the water storage tank 1 to the first drain pipe 2 and the second drain pipe 4 can be accelerated, thereby improving the overall efficiency of the equipment in spraying the lower slab.
[0043] The flow-pushing assembly 5 includes a horizontally arranged flow-pushing blade 51 located near the bottom of the water tank 1. A vertically arranged flow-pushing shaft 52 is fixedly connected to the middle of the upper side of the flow-pushing blade 51. The end of the flow-pushing shaft 52, away from the flow-pushing blade 51, is fixedly connected to a flow-pushing gear 53. A driving rack 54 engages one side of the flow-pushing gear 53. The driving rack 54 slides through the adjacent side wall of the water tank 1 near the drive plate 33 and is fixedly connected to the adjacent drive plate 33.
[0044] As the driving cylinder 34 drives the driving plate 33 to move, the driving plate 33 drives the connected active rack 54 to move, and the active rack 54 drives the connected flow-pushing gear 53 to rotate during the movement. The flow-pushing gear 53 rotates the connected flow-pushing shaft 52, and the flow-pushing shaft 52 rotates the flow-pushing blades 51 during the rotation. The flow-pushing blades 51 drive the water inside the water storage tank 1 toward the side wall of the water storage tank 1 during the rotation, thereby guiding the water to the first water outlet pipe 12 and the second water outlet pipe 13 for rapid discharge.
[0045] A protective sleeve 55 is further provided inside the water tank 1 , which covers the active rack 54 and the flow-pushing gear 53 , and the end of the protective sleeve 55 passes through the adjacent side wall of the water tank 1 and is fixedly connected to the side wall of the water tank 1 .
[0046] By providing the protective sleeve 55 , the active rack 54 and the flow-pushing gear 53 inside the water storage tank 1 can be protected.
[0047] The implementation principle of a laminar cooling system in an embodiment of the present application is as follows: when spray cooling is required for the slabs below the water storage tank 1, water is directed into the water storage tank 1 through the water inlet pipe 11, and then the drive cylinder 34 is activated. The drive cylinder 34 drives the drive plate 33 to move, which, during movement, rotates the multiple first and second drain pipes 2 and 4, and also drives the flow-pushing blades 51. As the first and second drain pipes 2 and 4 rotate, they evenly spray water onto the slabs below, achieving a uniform spraying process for the slabs.
[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
