[0044] 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.

[0045] like Figures 1 to 5 As shown, according to an embodiment of the present disclosure, a laminar cooling manifold device is proposed, including: a first pipeline 100; a branch pipe assembly 200, including a plurality of branch pipe portions 210, the plurality of branch pipe portions 210 are arranged along the extension direction of the first pipeline 100, the branch pipe portion 210 includes a second pipeline 211 and an electric control valve 212, the electric control valve 212 is connected between the first pipeline 100 and the second pipeline 211, and the plurality of electric control valves 212 can be independently controlled; a protective assembly 300, arranged in the first pipeline 100, the protective assembly 300 and the first pipeline 100 form a accommodating cavity 301, the electric control valve 212 is located in the accommodating cavity 301, the second pipeline 211 is penetrated by the protective assembly 300, and the output end of the second pipeline 211 is located outside the accommodating cavity 301.

[0046] The laminar cooling manifold device provided by the embodiment of the present disclosure includes a first pipeline 100, a branch pipe assembly 200 and a protection assembly 300, wherein the first pipeline 100 is arranged along the width direction of the strip to be cooled, that is, in practical applications, the extension direction of the first pipeline 100 can be set to maintain a high consistency with the width direction of the strip to be cooled. Accordingly, the first pipeline 100 can be connected to a cooling water supply device to facilitate access to cooling water; a plurality of branch pipe portions 210 of the branch pipe assembly 200 are arranged along the extension direction of the first pipeline 100, so that each branch pipe portion 210 can correspond to the width of the strip to be cooled. The electric control valve 212 of the branch pipe part 210 is connected between the second pipeline 211 of the branch pipe part 210 and the aforementioned first pipeline 100. The electric control valve 212 has an open state and a closed state. When the electric control valve 212 is in the open state, the corresponding second pipeline 211 is connected to the aforementioned first pipeline 100, so that the second pipeline 211 can be connected to the cooling water in the first pipeline 100 and the cooling water can be applied to the corresponding area in the width direction of the strip to be cooled. When the electric control valve 212 is in the closed state, the corresponding second pipeline 211 is cut off from the first pipeline 100. , so that the second pipeline 211 can be stopped from applying cooling water to the corresponding area in the width direction of the strip to be cooled, and each electric control unit can be independently controlled, so as to facilitate the regulation of the distribution range of the cooling water output by the laminar cooling manifold device in the width direction of the strip to be cooled; the protection component 300 is arranged on the first pipeline 100 and forms a receiving chamber 301 with the first pipeline 100, and the electric control valves 212 of each branch pipe part 210 are all located in the receiving chamber 301, so that the protection component 300 can cooperate with the first pipeline 100 to provide protection for each electric control valve 212, and the electric control valve 212 can be placed in a relatively In the closed space, and during the cooling operation, the cooling water flowing in the first pipeline 100 can exchange heat with the environment in the electric control valve 212 and the accommodating chamber 301, thereby realizing water cooling of the electric control valve 212 and the accommodating chamber 301, thereby reducing the impact of the high temperature environment of the production site on the operation of the electric control valve 212, providing guarantee for the stable and reliable operation of the electric control valve 212, and facilitating the stable adjustment of the distribution range of the coolant; the second pipeline 211 is arranged through the protective component 300 and the output end is located outside the accommodating chamber 301, so that the second pipeline 211 can apply cooling water to the strip to be cooled.

[0047] It can be understood that, based on the aforementioned arrangement, at least a portion of the second pipeline 211 will be located in the aforementioned accommodating chamber 301, so that when the electric control valve 212 is in an open state, the cooling water flowing through the electric control valve 212 and the second pipeline 211 can also cool the internal environment of the electric control valve 212 and the accommodating chamber 301, thereby further reducing the temperature of the electric control valve 212.

[0048] It can be understood that the extending direction of the first pipeline 100 is also the axial direction of the first pipeline 100 .

[0049] It should be noted that the laminar cooling manifold device provided in the embodiment of the present disclosure can be used as a device of a laminar cooling system in practical applications, for example, it can be used as a laminar cooling upper manifold device of a laminar cooling system. For example, the laminar cooling manifold device can be arranged above the conveying device of the laminar cooling system. The aforementioned conveying device is used to convey the strip to be cooled. It can be understood that the conveying direction of the conveying device matches the length direction of the strip to be cooled; the first pipeline 100 of the laminar cooling manifold device can be arranged along the width direction of the conveying device so that the extension direction of the first pipeline 100 maintains a high consistency with the width direction of the strip to be cooled. Accordingly, a plurality of branch pipes 210 can correspond to different areas in the width direction of the strip to be cooled, so that each second pipeline 211 can apply cooling liquid to different areas in the width direction of the strip to be cooled; in practical applications, the number of laminar cooling manifold devices can be multiple, and a plurality of laminar cooling manifold devices can be arranged along the conveying direction of the conveying device, so as to facilitate the control of the temperature distribution in the length direction of the strip to be cooled.

[0050] It should be noted that the distribution range of the laminar cooling water curtain output by the laminar cooling system in traditional technology cannot be adjusted in the width direction of the conveying device. The laminar cooling water curtain often completely covers the strip to be cooled in the width direction. When the strip to be cooled passes through the laminar cooling water curtain, the cooling rate of the edge area in the width direction of the strip to be cooled is usually faster than the cooling rate of the middle area in the width direction of the strip to be cooled, resulting in the temperature of the edge areas on both sides in the width direction of the strip being about 30 degrees Celsius lower than the temperature of the middle area. Affected by thermal expansion and contraction, the degree of shrinkage in the width direction of the strip is different, resulting in an uneven surface of the strip and edge waves, and easily causing large differences in the metallographic structure of the strip in the width direction, which has an adverse effect on the performance of the strip. The laminar cooling manifold device provided in the embodiment of the present invention is based on the above-mentioned setting, which is convenient for combining the temperature distribution in the width direction of the steel strip to be cooled during the production process, and specifically increasing the cooling water supply to the high-temperature area in the width direction of the steel strip to be cooled, and reducing the cooling water supply to the low-temperature area in the width direction of the steel strip to be cooled, so as to narrow the cooling speed difference in the width direction of the steel strip to be cooled, reduce the temperature difference between different areas in the width direction of the steel strip, avoid large metallographic structure differences in the width direction of the steel strip to be cooled, and help to ensure the plate shape and performance of the steel strip.

[0051] It can be understood that there are many ways to control the opening and closing states of each electric control valve 212 according to the temperature distribution in the width direction of the strip to be cooled. Exemplarily, the aforementioned laminar cooling system can be arranged in the laminar cooling coarse adjustment area, and the cold flow laminar cooling system can include multiple aforementioned laminar cooling manifold devices. For example, four laminar cooling manifold devices can be arranged along the conveying direction of the strip. Along the conveying direction, the laminar cooling coarse adjustment area can be divided into the front, middle and rear parts, and at least one aforementioned manifold device is arranged in each part; after the strip leaves the finishing mill, the number or number of manifolds that need to be opened to cool the strip can be preliminarily determined based on the strip model. The aforementioned strip model includes the strip steel grade information and the electric control valves that need to be opened corresponding to the strip steel grade information. The number and position information of the electric control valve 212 are provided; the temperature measuring devices are installed in the middle and rear of the laminar cooling rough adjustment area respectively. When the lateral temperature difference of the strip is detected to be beyond the limit, it is fed back to the front manifold device, and then the opening state of the electric control valve 212 located in the two side areas along the extension direction of the first pipeline 100 in the front manifold device is adjusted until the lateral temperature difference of the strip is within the limit; at the same time, the matching relationship between the adjustment data of the electric control valve 212 and the steel grade can be recorded in the strip model, so that the opening of the electric control gates on both sides of the manifold can be accurately controlled in the strip model when the same steel grade is rolled next time. In practical applications, other control methods can also be adopted for each electric control valve 212, which will not be limited too much here.

[0052] In summary, the laminar cooling manifold device can utilize the second pipelines 211 of the multiple branch pipe sections 210 of the branch pipe assembly 200 to apply cooling water to different areas in the width direction of the steel strip to be cooled, so as to cool the corresponding areas in the width direction of the steel strip. The electric control valves 212 of each branch pipe section 210 can regulate the conduction state of the corresponding second pipeline 211, and each electric control valve 212 can be independently controlled, so that the distribution range of the cooling water output by the laminar cooling manifold device can be regulated in the width direction of the steel strip to be cooled by adjusting the opening and closing states of each electric control valve 212, thereby facilitating the temperature distribution in the width direction of the steel strip to be cooled in the production process. , increase the cooling water supply to the high-temperature area in the width direction of the strip to be cooled, and reduce the cooling water supply to the low-temperature area in the width direction of the strip to be cooled, so as to narrow the temperature difference in the width direction of the strip to be cooled, avoid large metallographic structure differences in the width direction of the strip to be cooled, which is beneficial to ensuring the plate shape and performance of the strip; at the same time, the laminar cooling manifold device can use the protection component 300 to cooperate with the first pipeline 100 to protect each electric control valve 212, which is beneficial to reduce the impact of the high temperature environment on the operation of the electric control valve 212, and provide guarantee for the stable and reliable operation of the electric control valve 212, which is beneficial to achieve stable regulation of the distribution range of the cooling water output by the laminar cooling manifold device.

[0053] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some examples, the protective assembly 300 includes: a cover body portion 310 having an open end 302, and the open end 302 is arranged on the peripheral side of the first pipeline 100; a bracket portion 320, connected between the peripheral side of the first pipeline 100 and the cover body portion 310, the bracket portion 320, the cover body portion 310 and the first pipeline 100 form a accommodating cavity 301, and the second pipeline 211 is passed through the bracket portion 320; wherein, at least a portion of the bracket portion 320 is made of a heat-insulating material.

[0054] In this technical solution, the protective component 300 may include a cover body portion 310 and a bracket portion 320. The cover body portion 310, the bracket portion 320 and the first pipeline 100 may enclose the aforementioned accommodating chamber 301. The bracket portion 320 may be used to pass the second pipeline 211 so as to fix the position of the second pipeline 211, facilitate the second pipeline 211 to stably output cooling water, and help improve the uniformity of cooling water distribution; at least a portion of the bracket portion 320 may be made of heat-insulating material, thereby reducing the heat exchange efficiency between the accommodating chamber 301 and the production site environment, which is beneficial to keeping the temperature in the accommodating chamber 301 at a relatively low state, thereby providing a more reliable guarantee for the stable operation of the electric control valve 212.

[0055] Exemplarily, the cover body portion 310 can be arranged on the upper side of the bracket portion 320 and the first pipeline 100, and accordingly, the accommodating chamber 301 and the electric control valve 212 are also located on the upper side of the first pipeline 100, so that when there is a steel strip to be cooled on the lower side of the first pipeline 100, the heat insulation effect of the bracket portion 320 can be improved.

[0056] Exemplarily, the aforementioned heat insulating material may be, but is not limited to, aluminum silicate fiber wool.

[0057] like Figure 2 , Figure 4 and Figure 5 As shown, in some examples, the cover body portion 310 includes: a cover body main body 311, having an open end 302, a cover opening formed at one end of the cover body 311 away from the open end 302, and a bracket portion 320 connected between the peripheral side of the first pipeline 100 and the cover body 311; a cover body 312, hinged to the cover body main body 311, for opening or covering the cover opening; wherein the cover body 311 is made of metal material, and the cover body 312 is made of transparent material.

[0058] In this technical solution, the cover body 310 may include a cover body 311 and a cover body 312. The cover body 312 can open or cover the cover opening of the cover body 311 by rotating relative to the cover body 311, so as to facilitate the opening or closing of the accommodating chamber 301, and further facilitate the maintenance and replacement of the components in the accommodating chamber 301 by the operating personnel, such as the maintenance and replacement of the electric control valve 212; the aforementioned cover body 311 can be made of metal material, which is beneficial to improve the heat dissipation efficiency of the cover body 311 and to dissipate heat for the components in the accommodating chamber 301; the aforementioned cover body 312 can be made of transparent material, so that when the cover body 312 covers the cover opening, it is convenient for the operating personnel to observe the situation in the accommodating chamber 301 through the cover body 312, so as to facilitate the operating personnel to inspect the components in the accommodating chamber 301.

[0059] For example, the aforementioned metal material may be, but is not limited to, stainless steel; and the aforementioned transparent material may be, but is not limited to, polycarbonate.

[0060] like Figure 2 , Figure 4 and Figure 5 As shown, in some examples, the cover body portion 310 further includes: a sealing member 313 for sealing a connection gap between the cover body 312 and the cover body 311 when the cover body 312 covers the cover opening.

[0061] In this technical solution, the cover body 310 can also include a sealing member 313, so that when the cover body 312 covers the cover opening, the cover body 310 can use the sealing member 313 to seal the connection gap between the cover body 312 and the cover body 311, thereby improving the sealing performance of the accommodating chamber 301, reducing the impact of the high temperature environment on the operation of the electric control valve 212, and preventing steam from penetrating into the accommodating chamber 301 through the aforementioned connection gap, which is beneficial to providing protection for the stable and reliable operation of the electric control valve 212.

[0062] like Figure 2 As shown, in some examples, the bracket portion 320 includes: a bracket body 321, which is arranged at the open end 302 of the cover body portion 310, and the bracket body 321 is formed with a connecting hole, and the second pipeline 211 is passed through the connecting hole; a connecting piece 322, which is connected between the peripheral side of the first pipeline 100 and the bracket body 321, and the connecting piece 322 forms a cavity; a filling piece, which is arranged in the cavity; wherein the filling piece is made of a heat insulating material.

[0063] In this technical solution, the bracket part 320 can use the bracket body 321 to fix the second pipeline 211, and a filling piece made of heat-insulating material can be arranged in the connecting piece 322 connected between the bracket body 321 and the first pipeline 100, thereby improving the heat insulation effect of the bracket part 320 and reducing the heat exchange efficiency between the accommodating chamber 301 and the production site environment, which is beneficial to maintaining the temperature in the accommodating chamber 301 at a relatively low state, thereby providing a more reliable guarantee for the stable operation of the electric control valve 212.

[0064] It can be understood that the aforementioned filling piece can be made of aluminum silicate fiber wool.

[0065] like Figure 2 As shown, in some examples, the branch pipe portion 210 further includes: a first quick connector 213 connected between the electric control valve 212 and the first pipeline 100 ; and / or a second quick connector 214 connected between the electric control valve 212 and the second pipeline 211 .

[0066] In this technical solution, the first pipeline 100 and the electric control valve 212 can be connected via the first quick connector 213 , which is conducive to improving the convenience of disassembly and assembly of the electric control valve 212 and facilitating the maintenance and replacement of the electric control valve 212 .

[0067] In this technical solution, the second pipeline 211 and the electric control valve 212 can be connected via the first quick connector 213 , which is conducive to improving the convenience of disassembly and assembly of the second pipeline 211 and facilitating the maintenance and replacement of the second pipeline 211 .

[0068] It is understandable that the branch pipe portion 210 may include the first quick connector 213 and the second quick connector 214 at the same time, so that the second pipeline 211 and the electric control valve 212 can be easily repaired and replaced independently.

[0069] like Figure 2 As shown, in some examples, each branch pipe portion 210 includes at least two second pipelines 211, and the branch pipe portion 210 also includes: a liquid separation component 215, having a liquid inlet end and at least two liquid outlet ends, the liquid inlet end is connected to the electric control valve 212, and each liquid outlet end is connected to a second pipeline 211.

[0070] In this technical solution, each branch pipe portion 210 may include two or more second pipelines 211, which is beneficial to improving the distribution uniformity and continuity of the cooling water output by the laminar cooling manifold device; accordingly, the branch pipe portion 210 may also include a liquid separator 215, and the second pipelines 211 may be connected one-to-one to the liquid outlet end of the liquid separator 215, and accordingly, the liquid inlet end of the liquid separator 215 may be connected to the first pipeline 100 through the electric control valve 212, thereby reducing the number of openings in the first pipeline 100.

[0071] For example, Figure 2 As shown, the liquid separation member 215 has two liquid outlet ends, and each branch pipe portion 210 includes two second pipelines 211 , and the two second pipelines 211 extend to opposite sides of the first pipeline 100 respectively.

[0072] For example, Figure 2 As shown, when the branch pipe portion 210 includes the aforementioned second quick connector 214 , the second quick connector 214 is connected between the liquid inlet end of the liquid separation member 215 and the electric control valve 212 .

[0073] like Figure 2 and Figure 3 As shown, in some examples, the number of the branch pipe assemblies 200 is at least two, and the at least two branch pipe assemblies 200 are arranged at intervals along the circumference of the first pipeline 100 .

[0074] In this technical solution, the number of branch pipe assemblies 200 can be two or more, and multiple branch pipe assemblies 200 can be arranged at circumferential intervals along the first pipeline 100, so that when the extension length of the first pipeline 100 is constant, the number of branch pipe sections 210 can be further increased, which is beneficial to further improve the distribution uniformity and continuity of the cooling water output by the laminar cooling manifold device.

[0075] like Figure 3 As shown, in some examples, at least two branch pipe assemblies 200 are staggered along the extension direction of the first pipeline 100 .

[0076] In this technical solution, multiple branch pipe assemblies 200 can be staggered along the extension direction of the first pipeline 100, so as to further improve the arrangement density of the branch pipe parts 210 in the width direction of the strip to be cooled, and can make the cooling water flows output by the branch pipe parts 210 of the multiple branch pipe assemblies 200 staggered, which is beneficial to further improve the distribution uniformity and continuity of the cooling water output by the laminar cooling manifold device.

[0077] According to a second aspect of an embodiment of the present disclosure, a laminar cooling system is proposed, comprising: a laminar cooling manifold device as proposed in any one of the first aspects above.

[0078] In some feasible examples, the laminar cooling system provided by the embodiments of the present disclosure may further include a conveying device, wherein the number of the aforementioned laminar cooling manifold devices is multiple, and the multiple laminar cooling manifold devices are arranged along the conveying direction of the conveying device, and the first pipeline 100 extends along the width direction of the conveying device. The conveying device is used to convey the strip to be cooled, and the width direction of the strip to be cooled is consistent with the width direction of the conveying device.

[0079] In addition, since the laminar cooling system provided by the embodiment of the present disclosure includes the laminar cooling manifold device proposed in any one of the first aspects above, it has all the beneficial effects of the laminar cooling manifold device, which will not be elaborated here.

[0080] In the present disclosure, the terms "first", "second", and "third" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance; the term "plurality" refers to two or more, unless otherwise expressly defined. The terms "installed", "connected", "connected", "fixed", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; "connected" can be a direct connection or an indirect connection through an intermediate medium.
