BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Various other advantages and benefits will become apparent to those of ordinary skill in the art by reading the detailed description of the exemplary embodiments below. The accompanying drawings are only for the purpose of illustrating exemplary embodiments and are not to be considered as limiting the present disclosure. Also, the same reference symbols are used throughout the accompanying drawings to represent the same components. In the accompanying drawings:

[0030] in, Figure 1 The corresponding relationship between the reference numerals and the component names is as follows:

[0031] Tube body 110 , nozzle 120 , valve body 130 . DETAILED DESCRIPTION

[0032] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0033] like Figure 1 As shown, according to an embodiment of the present disclosure, an air blowing device is proposed, including: a tube body 110, the tube body 110 is provided with an air inlet and an air outlet; a nozzle 120, connected to the air outlet; a valve body 130, connected to the air inlet; wherein, when the valve body 130 is in a conducting state, the gas enters the tube body 110 from the valve body 130, and is sprayed toward the strip from the nozzle 120.

[0034] The air blowing device proposed in the embodiment of the present disclosure includes a tube body 110, a nozzle 120 and a valve body 130, wherein the valve body 130 is connected to the air inlet of the tube body 110, and the nozzle 120 is connected to the air outlet of the tube body 110. In actual application, the valve body 130 is opened to put the valve body 130 in a conducting state. At this time, the gas will enter the tube body 110 from the valve body 130 through the air inlet of the tube body 110, and enter the nozzle 120 from the air outlet of the tube body 110, and then be sprayed toward the strip from the nozzle 120 to blow away the cooling water on the surface of the strip.

[0035] It can be understood that the valve body 130 is connected to the gas source, the nozzle 120 is arranged toward the strip, and the gas source can be high-pressure gas, which is conducive to the gas sprayed from the nozzle 120 to quickly blow away the cooling water on the surface of the strip.

[0036] It should be noted that in the prior art, during the production process of the continuous casting and rolling production line, the low-temperature coiling process is usually adopted for duplex steel in the headless rolling mode, and the temperature drop in the laminar cooling area needs to reach more than 500°C, so a large amount of cooling water is required, which leads to a large amount of cooling water remaining on the surface of the strip. The cooling water will form a water film on the surface of the strip, and the water film has a certain lubricity, which leads to the inability to coil the steel coil tightly during the coiling process, thereby causing problems of loose coiling and flat coiling, which has an adverse effect on production stability and product quality. Based on the above-mentioned setting, the embodiment of the present disclosure can break the cooling water film on the surface of the strip by air blowing, and blow away the cooling water, thereby reducing the probability of loose coiling and flat coiling problems, which is conducive to improving production stability and product quality.

[0037] In some examples, such as Figure 1 As shown, a plurality of air outlets are arranged at intervals on the side of the tube body 110 , and each air outlet corresponds to a nozzle 120 .

[0038] In the above technical solution, the number of air outlets can be set to multiple, and the multiple air outlets are arranged at intervals on the side of the tube body 110, and each air outlet is correspondingly provided with a nozzle 120, so that the surface of the strip can be blown from multiple positions, increasing the area of ​​air blowing, which is beneficial to improving the efficiency of cooling water extraction.

[0039] It can be understood that the gas outlet can be arranged along the extension direction of the tube body 110, and the tube body 110 can be arranged along the axial direction of the curling of the strip, so that the gas sprayed by the nozzle 120 can cover the entire width direction of the strip, thereby completing the removal of cooling water during the curling process of the strip, which is beneficial to improving production efficiency.

[0040] In some examples, a plurality of tubes 110 are provided, and at least one of the tubes 110 has a bent section.

[0041] In the above technical solution, the number of tube bodies 110 can be set to multiple, so that the multiple tube bodies 110 can be used to blow air to the strip steel from different positions, which is beneficial to improving the efficiency of air blowing. In addition, among the multiple tube bodies 110, at least one tube body 110 is formed with a bending section, and the bending section can make the tube body 110 have different position heights, which is beneficial to improving the applicability of the device.

[0042] For example, the bending section may be bent in a “J” shape, and the position height of the nozzle 120 may be adjusted by rotating the tube body 110 .

[0043] In some examples, it further includes: an adjusting mechanism, the tube body 110 is connected to the adjusting mechanism, and the adjusting mechanism is used to adjust the spraying angle of the nozzle 120 .

[0044] In the above technical solution, the air blowing device also includes an adjusting mechanism, which is connected to the tube body 110. The adjusting mechanism can adjust the direction of the air outlet of the tube body 110 to adjust the spray angle of the nozzle 120, so that the gas coverage range sprayed by the nozzle 120 can be adjusted, thereby realizing the cooling water removal of the strip at different positions, which is beneficial to improve the applicability of the device.

[0045] In some examples, the adjustment mechanism includes: a bracket, a supporting end of the bracket is formed with a notch, and the tube body 110 can move along the axial direction of the notch and / or rotate along the radial direction of the notch; a locking member, arranged in the notch, for locking the rotation angle of the tube body 110.

[0046] In the above technical solution, the adjustment mechanism includes a bracket and a locking member, wherein the locking member is arranged at the notch of the supporting end of the bracket, the supporting end of the bracket supports the tube body 110, and the tube body 110 is located at the notch of the supporting end of the bracket; the tube body 110 can move along the axial direction of the notch, so that the nozzle 120 can adjust the jet position along the axial direction of the notch, thereby realizing the cooling water extraction of the strip steel at different positions, which is beneficial to improving the applicability of the device.

[0047] In the above technical solution, the tube body 110 can rotate along the radial direction of the notch so that the nozzle 120 can adjust the jet position along the radial direction of the notch. The locking member can lock the tube body 110 when the tube body 110 rotates along the radial direction of the notch, so that the tube body 110 maintains the rotation angle, thereby realizing the cooling water removal of the strip steel at different positions, which is beneficial to improving the applicability of the device.

[0048] In the above technical solution, the tube body 110 can move along the axial direction of the notch and can also rotate along the radial direction of the notch, and the effect will not be elaborated here.

[0049] In some examples, the locking member is a bolt, a threaded hole is provided at the notch of the bracket, and the bolt is screwed into the threaded hole and is used to abut against the tube body 110 .

[0050] In the above technical solution, the locking member can be a bolt, and a threaded hole is opened at the notch of the bracket. In actual application, the rotation angle of the tube body 110 is adjusted, the bolt is screwed into the threaded hole, and the bolt is abutted against the tube body 110. The friction between the bolt and the tube body 110 is used to fix the rotation angle of the tube body 110, thereby adjusting the injection angle of the nozzle 120.

[0051] In some examples, the method further includes: a gasket disposed in the notch.

[0052] In the above technical solution, the air blowing device further includes a gasket, which is arranged inside the notch to increase the friction between the gasket and the tube body 110, thereby facilitating the fixing of the rotation angle of the tube body 110.

[0053] In some examples, it also includes: a gas pressure detection component, which is disposed in the tube body 110 and is used to detect the gas pressure in the tube body 110.

[0054] In the above technical solution, the air blowing device also includes an air pressure detection component, which can be set on the tube body 110 to detect the gas pressure inside the tube body 110 and monitor the pressure inside the tube body 110 in real time to ensure that the gas pressure inside the tube body 110 can meet the requirements for removing cooling water.

[0055] It is understandable that when the gas pressure inside the tube body 110 is too high, safety accidents are likely to occur. Therefore, the gas pressure detection component is also helpful in ensuring the safety of the device.

[0056] In some examples, the invention further includes: a position detection member for detecting the distance between the steel strip and the nozzle 120;

[0057] The controller, the valve body 130 and the position detection element are electrically connected to the controller. When the distance between the steel strip and the nozzle 120 is less than or equal to the preset distance, the controller controls the valve body 130 to open. When the distance between the steel strip and the nozzle 120 is greater than the preset distance, the controller controls the valve body 130 to close.

[0058] In the above technical solution, the air blowing device also includes a position detection component and a controller, and the valve body 130 and the position detection component are both electrically connected to the controller, wherein the position detection component can detect the distance between the steel strip and the nozzle 120, and transmit the distance information between the steel strip and the nozzle 120 to the controller, and the controller can receive the distance information provided by the position detection component, and control the valve body 130 according to the distance information. In practical applications, a preset distance that can meet the air blowing requirements can be preset, when the distance between the steel strip and the nozzle 120 is less than or equal to the preset distance, the controller can control the valve body 130 to open, and when the distance between the steel strip and the nozzle 120 is greater than the preset distance, the controller can control the valve body 130 to close, thereby ensuring that the gas sprayed by the nozzle 120 can blow away the cooling water on the surface of the steel strip, and when the distance between the steel strip and the nozzle 120 is too far, it can be avoided that the nozzle 120 continues to spray gas, and the cooling water on the surface of the steel strip cannot be blown away, and energy is wasted.

[0059] In some examples, valve body 130 is a pneumatic butterfly valve.

[0060] In the above technical solution, the valve body 130 may adopt a pneumatic butterfly valve, which has fast response, high reliability, strong adjustment performance, low cost and easy maintenance.
