[0035] like Figures 1 to 4As shown, this embodiment proposes a water cooling device for steel rolling, including a water tank 1, a water inlet chamber 11 is provided inside the water tank 1, a water inlet port 12 is provided on a side of the water tank 1 close to the water inlet chamber 11, and the water inlet port 12 can be connected with the water inlet chamber 11, a cooler 2 is provided in the water tank 1, and the cooler 2 can be used for water cooling the steel rolling passing through the water tank 1; in addition, a water inlet control pipeline 3 is also provided on the water tank 1, and the water inlet control pipeline 3 can be used to connect the water inlet chamber 11 with the cooler 2, and a valve body 4 is provided on the water inlet control pipeline 3, and the valve body 4 can be used to control the opening and closing of the water inlet control pipeline 3. In this way, external water flows into the water inlet chamber 11 through the water inlet 12, and the water inlet chamber 11 and the cooler 2 are connected through the water inlet control pipeline 3, so that the opening and closing of the water inlet control pipeline 3 can be controlled by the valve body 4 on the water inlet control pipeline 3, and then the cooling water in the water inlet chamber 11 can pass through the cooler 2 to cool the rolled steel passing through the water tank 1. Through the integrated structure of the water tank 1 and the water inlet control pipeline 3, on the one hand, the separate valve table is eliminated, making the entire water cooling system simpler, realizing modular integration and facilitating installation and maintenance; on the other hand, it also improves the control response speed of the water cooling device, which is beneficial to improving the yield rate and rolling speed, obtaining a better metallographic structure, and realizing the needs of high-speed rolling.

[0036] For further information, see Figure 1 As shown, the water tank 1 is also provided with a through hole 13, and the through hole 13 allows the rolled steel to pass through the water tank 1. In this way, by accurately setting the position of the through hole 13, when the rolled steel passes through the through hole 13, it can be water-cooled by the cooler 2, which is accurate and convenient.

[0037] Preferably, see Figure 1 As shown, the number of the coolers 2 is multiple, and the coolers 2 are spaced apart along the length direction of the water tank 1. Correspondingly, the number of the water inlet control pipelines 3 is also set to multiple, so as to ensure that the number of coolers 2 corresponds to the number of water inlet control pipelines 3. In this way, by setting multiple coolers 2, multiple locations of the steel rolling can be cooled at the same time, the cooling efficiency is improved, and the rolling speed is further increased.

[0038] For further information, see Figure 3 As shown, the cooler 2 includes a nozzle seat 21 and a cooling nozzle 22. The nozzle seat 21 is arranged in the water tank 1. The cooling nozzle 22 is mounted on the nozzle seat 21 and communicated with the water inlet control pipeline 3. In addition, the valve body 4 is mounted on the water inlet control pipeline 3 on the side close to the cooling nozzle 22. In this way, by controlling the water inlet control pipeline 3, the water inlet cavity 11 is connected with the cooling nozzle 22, so that the rolled steel can be cooled by the cooling nozzle 22. In addition, by arranging the valve body 4 on the side close to the cooling nozzle 22, the control water path is shorter and the response is faster, which meets the requirements of high-speed rolling.

[0039] For further information, see Figure 3 As shown, the valve body 4 includes a pneumatic valve 41 and / or a manual valve 42, and the pneumatic valve 41 and / or the manual valve 42 are arranged on the water inlet control pipeline 3. In this way, the water inlet control pipeline 3 can be opened and closed by the pneumatic valve 41 and / or the manual valve 42 to realize the control of the conduction or closing of the water inlet control pipeline 3. Preferably, in this embodiment, the valve body 4 includes the pneumatic valve 41 and the manual valve 42, so that when the pneumatic valve 41 needs to be repaired, the water inlet control pipeline 3 can be opened and closed by the manual valve 42.

[0040] For further information, see Figure 2 and Figure 4 As shown, the water tank 1 is also provided with a water outlet 14. Thus, by providing the water outlet 14, the cooling water sprayed by the cooler 2 is discharged through the water outlet 14, so as to avoid the cooling water being retained in the water tank 1 for a long time, causing the water temperature to rise, thereby affecting the water cooling effect.

[0041] For further information, see Figure 4 As shown, the water tank 1 is also provided with a water outlet control pipeline 5, which is used to connect the water inlet chamber 11 with the water outlet 14. In addition, the water outlet control pipeline 5 is provided with a valve body 4 for controlling its opening and closing. In the present application, the valve body 4 on the water outlet control pipeline 5 has the same structure as the valve body 4 on the water inlet control pipeline 3. In this way, when the valve body 4 on the water inlet control pipeline 3 is closed, the valve body 4 on the water outlet control pipeline 5 is opened synchronously, so that the impact of excessive water flow pressure fluctuation on the water inlet control pipeline 3 or the water outlet control pipeline 4 on the cooling system can be avoided, and the switching response speed of the valve body 4 is also improved; when the cooling nozzle 22 is opened for cooling, the valve body 4 on the water outlet control pipeline 5 is closed at this time, so as to ensure the cooling water pressure, so that the water sprayed by the cooling nozzle 22 can be directly discharged through the water outlet 14.

[0042] For further information, see Figure 1 As shown, the steel rolling water cooling device further includes a support 6, and the water tank 1 is arranged on the support 6. In this way, by arranging the support 6, the water tank 1 can be well supported, and at the same time, it is also convenient to arrange the water inlet 12 and the water outlet 14 at the bottom of the water tank 1, so that the structure of the steel rolling water cooling device is more compact, and by arranging the water inlet 12 and the water outlet 14 at the bottom of the water tank 1, the stability of the water flow entering the water tank 1 is guaranteed, and the turbulence phenomenon is avoided, which affects the cooling effect of the steel rolling.

[0043] For further information, see Figure 1 and Figure 2As shown, the steel rolling water cooling device also includes a protective cover 7, which is rotatably mounted on the water tank 1. By providing the protective cover 7, the protective cover 7 can prevent the cooling water from splashing around during the spraying process, and avoid the cooling water splashing on the equipment around the water tank 1, causing damage to the equipment or affecting the normal operation of the equipment.

[0044] For further information, see Figure 1 and Figure 2 As shown, a pair of clamping plates 15 are provided at intervals on the water tank 1, and a pair of connecting plates 71 are installed on the protective cover 7, and the pair of connecting plates 71 are located between the pair of clamping plates 15. In addition, a connecting shaft is provided on the water tank 1, and the connecting shaft can be used to hinge the pair of clamping plates 15 and the pair of connecting plates 71. In this way, the pair of clamping plates 15 and the pair of connecting plates 71 are hinged through the connecting shaft, so that the protective cover 7 can be manually opened or closed; at the same time, since the protective cover 7 can rotate around the connecting shaft, the angle of the protective cover 7 can be adjusted according to actual needs, so that the protective cover 7 can better prevent the splashing of cooling water.

[0045] For further information, see Figure 1 As shown, a driving cylinder 8 is further provided on the outer side of the water tank 1, and the movable section of the driving cylinder 8 is connected to a pair of connecting plates 7. In this way, the connecting plates 7 are driven to move by the driving cylinder 8, thereby driving the protective cover 7 to rotate around the connecting axis, so that the opening and closing of the protective cover 7 can be conveniently controlled, thereby improving the convenience of operation.
