Detailed Implementation

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] It should be noted that all directional indications in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0050] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0051] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0052] The inventors discovered that the main reason for edge cracking and edge waviness in strip steel is that, in related technologies, in order to adapt the laminar cooling device to strip steel of different widths, the upper layer of cold water sprayed from the upper manifold of the laminar cooling device covers a wide range. This results in the upper layer of cold water sprayed on both sides of the upper manifold along the width direction of the strip steel when producing strip steel with a smaller width, causing the temperature of the strip steel edge to drop rapidly. The excessively low temperature of the strip steel edge causes a phase change in the strip steel structure, resulting in frequent edge cracking and edge waviness.

[0053] Therefore, in related technologies, strip steel often suffers from defects such as edge cracks and edge waviness after layer cooling. This application provides a flow guiding device and a strip steel cooling system, which can at least partially solve the technical problem of edge cracks and edge waviness frequently occurring in strip steel after layer cooling.

[0054] This application is described below with reference to the accompanying drawings and specific embodiments:

[0055] The flow guiding device 100 of this application guides the upper layer cold water discharged from both sides of the upper cooling manifold 200 to the outside of the strip steel 400 through the first water collection box 120 and the second water collection box 130, so as to prevent the upper layer cold water discharged from both sides of the upper cooling manifold 200 from falling on the edge of the strip steel 400, reduce the temperature drop at the edge of the strip steel 400, and thus improve the problems of edge cracking and edge waviness of the strip steel 400.

[0056] The flow guiding device 100 is used to guide the upper chilled water discharged from the upper cooling manifold 200, such as... Figure 5 As shown, the laminar cooling manifold 200 has a first side 210 and a second side 220 arranged opposite to each other along the X direction, and a plurality of laminar cooling manifolds 200 are spaced apart along the Y direction.

[0057] like Figure 1 and Figure 5 As shown, the flow guiding device 100 includes: a mounting base 110, a first water collection box 120, and a second water collection box 130. The mounting base 110 is connected to the upper manifold of the laminar flow cooling system 200. The first water collection box 120 has a first flow guiding groove 120a, which is slidably connected to the mounting base 110 along the X direction, and the first flow guiding groove 120a is located below the first side 210. The second water collection box 130 has a second flow guiding groove 130a, which is slidably connected to the mounting base 110 along the X direction, and the second flow guiding groove 130a is located below the second side 220. The first outlet 120b of the first flow guiding groove 120a is located on the side of the first flow guiding groove 120a away from the second flow guiding groove 130a, and the second outlet 130b of the second flow guiding groove 130a is located on the side of the second flow guiding groove 130a away from the first flow guiding groove 120a.

[0058] like Figure 6 As shown, along the length of the roller conveyor 300, multiple upper cooling manifolds 200 are spaced apart above the roller conveyor 300, with the length of the upper cooling manifolds 200 parallel to the width of the roller conveyor 300. During the layer cooling of the strip 400, the strip 400 is located below the upper cooling manifolds 200 and is conveyed via the roller conveyor 300 below. The upper cooling manifolds 200 spray upper-layer cold water downwards, which is then sprayed onto the upper surface of the strip 400.

[0059] In this application, the X direction is the width direction of the roller conveyor 300 and also the length direction of the upper cooling manifold 200; the Y direction is the length direction of the roller conveyor 300; and the Z direction is the height direction.

[0060] like Figure 5As shown, in use, the mounting base 110 is connected to both the upper manifold of the laminar cooling system 200 and the first water collection box 120 and the second water collection box 130. The mounting base 110 supports the first water collection box 120 and the second water collection box 130, so that the first water collection box 120 can be stably located below the first side 210 of the upper manifold of the laminar cooling system 200, and the second water collection box 130 can be stably located below the second side 220 of the upper manifold of the laminar cooling system 200.

[0061] The mounting base 110 can be connected to the laminar cooling upper manifold 200 in various ways, such as snap-fit, bolt connection, or binding connection, which is not limited in this application. In some embodiments, the mounting base 110 is welded to the laminar cooling water beam of the laminar cooling upper manifold 200.

[0062] The first guide channel 120a is located below the first side 210 of the laminar cooling upper manifold 200, so that the first guide channel 120a can collect the upper layer of cold water discharged from the first side 210. The upper layer of cold water discharged from the first side 210 of the laminar cooling upper manifold 200 falls into the first guide channel 120a, and is finally discharged from the first outlet 120b to the outside of the strip 400.

[0063] The second guide channel 130a is located below the second side 220 of the laminar cooling upper manifold 200, so that the second guide channel 130a can collect the upper layer of chilled water discharged from the second side 220. The upper layer of chilled water discharged from the second side 220 of the laminar cooling upper manifold 200 falls into the second guide channel 130a, and is finally discharged from the second outlet 130b to the outside of the strip 400.

[0064] The first water collection box 120 and the second water collection box 130 are both slidably connected to the mounting base 110 along the X direction, so that the first water collection box 120 and the second water collection box 130 can move along the X direction.

[0065] The first outlet 120b of the first guide channel 120a is located on the side of the first guide channel 120a away from the second guide channel 130a, and the second outlet 130b of the second guide channel 130a is located on the side of the second guide channel 130a away from the first guide channel 120a. In other words, the first outlet 120b and the second outlet 130b are arranged opposite to each other.

[0066] After the flow guiding device 100 is designed as described above:

[0067] On one hand, the upper chilled water discharged from the first side 210 of the laminar cooling manifold 200 will fall into the first guide channel 120a and flow along the first guide channel 120a, eventually being discharged outside the strip 400 through the first outlet 120b, avoiding falling onto the edge of the strip 400; the upper chilled water discharged from the second side 220 of the laminar cooling manifold 200 will fall into the second guide channel 130a and flow along the second guide channel 130a, eventually being discharged outside the strip 400 through the second outlet 130b, avoiding falling onto the edge of the strip 400. The upper chilled water from both sides of the laminar cooling manifold 200 is collected and guided to the outside of the strip 400, simultaneously improving problems such as edge cracks and edge waves caused by excessively rapid and uneven cooling on both sides of the strip 400, thus helping to improve the quality of the strip 400.

[0068] On the other hand, the first water collection box 120 and the second water collection box 130 are both slidably connected to the mounting base 110 along the X direction, so that the first water collection box 120 and the second water collection box 130 can move along the X direction, so that the positions of the first guide groove 120a and the second guide groove 130a can be adaptively changed according to the position of the edge of the strip 400, adapting to strips 400 of different widths, which facilitates the use of the guide device 100.

[0069] In order to increase the flow rate of water in the first water collection box 120, in some embodiments, the first guide channel 120a is inclined, with the side of the first guide channel 120a closer to the first water outlet 120b being lower and the side farther from the first water outlet 120b being higher.

[0070] In order to increase the flow rate of water in the second water collection box 130, in some embodiments, the second guide channel 130a is inclined, with the side of the second guide channel 130a closer to the second water outlet 130b being lower and the side farther away from the second water outlet 130b being higher.

[0071] like Figure 1 and Figure 5 As shown, in some embodiments, the first water collection box 120 has a plurality of first guide channels 120a arranged at intervals along the Y direction, and the plurality of first guide channels 120a are arranged in a one-to-one correspondence with a plurality of first sides 210.

[0072] Multiple first guide channels 120a are arranged one-to-one with multiple first sides 210, that is, each first guide channel 120a is located below each first side 210. With this design, the first water collection box 120 can simultaneously collect the upper layer cold water discharged from the first side 210 of multiple upper cooling manifolds 200, which will help reduce the number of guide devices 100 and save production costs for enterprises.

[0073] In some embodiments, the second water collection box 130 has a plurality of second guide channels 130a arranged at intervals along the Y direction, and the plurality of second guide channels 130a are arranged in a one-to-one correspondence with a plurality of second sides 220.

[0074] Multiple second flow guide channels 130a are arranged one-to-one with multiple second sides 220, that is, each second flow guide channel 130a is located below each second side 220. With this design, the second water collection box 130 can simultaneously collect the upper layer cold water discharged from the second sides 220 of multiple upper cooling manifolds 200, which will help reduce the number of flow guide devices 100 and save production costs for enterprises.

[0075] In some embodiments, such as Figure 1 As shown, the first water collection box 120 has two first guide channels 120a spaced apart along the Y direction, and the second water collection box 130 has two second guide channels 130a spaced apart along the Y direction.

[0076] In some embodiments, the mounting base 110 includes a slide rod 111 and a connecting assembly 112. The slide rod 111 is arranged along the X direction, and the first water collection box 120 and the second water collection box 130 are both slidably connected to the slide rod 111. The connecting assembly 112 is connected to the slide rod 111 and is used to connect to the upper manifold 200 of the laminar flow cooling system.

[0077] The slide rod 111 being arranged along the X-direction means that the length direction of the slide rod 111 is parallel to the X-direction. The connecting assembly 112 is connected to both the slide rod 111 and the upper cooling manifold 200. The connecting assembly 112 supports the slide rod 111, thus fixing the slide rod 111. The connection methods between the connecting assembly 112 and the slide rod 111, as well as the connection methods between the connecting assembly 112 and the upper cooling manifold 200, are various, such as welding, snap-fitting, bolting, etc.

[0078] With the above design, the mounting base 110 includes a slide rod 111 and a connecting component 112. The slide rod 111 and the connecting component 112 can be processed independently and connected to form the mounting base 110, which facilitates the processing and manufacturing of the mounting base 110.

[0079] In some embodiments, the mounting base 110 has two connecting components 112, which are spaced apart along the X direction. The arrangement of the two connecting components 112 helps to improve the strength of the connection between the mounting base 110 and the laminar flow manifold 200.

[0080] The cross-section of the slide bar 111 can be circular, rectangular, etc., and is not limited in this application. The slide bar 111 can be solid or hollow.

[0081] like Figure 5As shown, in some embodiments, the slide bar 111 is located between two adjacent upper cooling manifolds 200, and the connecting assembly 112 is connected to both adjacent upper cooling manifolds 200.

[0082] The laminar cooling manifolds 200 are spaced apart, with a Y-axis spacing between adjacent laminar cooling manifolds 200. The slide bar 111 is located between adjacent laminar cooling manifolds 200, utilizing the Y-axis spacing between them. This helps improve the compactness of the flow guiding device 100 and the laminar cooling manifolds 200, increasing space utilization. The connecting assembly 112 connects to both adjacent laminar cooling manifolds 200, improving the stability of the flow guiding device 100 after installation.

[0083] The structure of the connecting component 112 is diverse. The connecting component 112 may include one component or multiple components. For example, the connecting component 112 may be a rod, a plate, etc., and no limitation is made in this application.

[0085] In some embodiments, the first connector 1121 and the second connector 1122 are both channel steels, and the first connector 1121 and the second connector 1122 are welded and fixed together, as are the slide rod 111 and the second connector 1122.

[0086] In some embodiments, the first water collection box 120 includes a first water collection element 121, a first sliding element 122, a first column assembly 123, and a first inclined column assembly 124. The first water collection element 121 has a first guide channel 120a; the first sliding element 122 is slidably connected to the mounting base 110; the first column assembly 123 is connected to the side of the first water collection element 121 near the second water collection box 130 and the first sliding element 122; the first inclined column assembly 124 is connected to the side of the first water collection element 121 away from the second water collection box 130 and the first sliding element 122.

[0087] The first upright assembly 123 is connected to the first water collection component 121 and the first sliding component 122, and the first inclined column assembly 124 is also connected to the first water collection component 121 and the first sliding component 122. The first upright assembly 123 and the first inclined column assembly 124 are connected to different parts of the first water collection component 121 so that the first water collection component 121 is subjected to uniform force at all parts, ensuring the stability of the structure of the first water collection box 120.

[0088] In some embodiments, the first column assembly 123 and the first inclined column assembly 124 are arranged at an acute angle.

[0089] like Figure 1 As shown, in some embodiments, the first column assembly 123 includes a first column 1231, a second column 1232, and a first column connector 1233. The first column 1231 and the second column 1232 are spaced apart along the Y direction.

[0090] like Figure 1 As shown, in some embodiments, the second inclined column assembly 134 includes a first inclined column 1241, a second inclined column 1242, and a first inclined column connector 1243. The first inclined column 1241 and the second inclined column 1242 are spaced apart along the Y direction. The ends of the first inclined column 1241 and the second inclined column 1242 near the first water collecting component 121 are both fixedly connected to the first water collecting component 121. The first inclined column connector 1243 is connected to the end of the first inclined column 1241 away from the first water collecting component 121 and the end of the second inclined column 1242 away from the first water collecting component 121. The first inclined column connector 1243 is also connected to the first sliding member 122.

[0091] In some embodiments, the first column 1231, the second column 1232, the first column connector 1233, the first inclined column 1241, the second inclined column 1242, and the first inclined column connector 1243 are all angle steel.

The slide rod 111 is arranged along the X direction; the connecting assembly 112 is connected to the slide rod 111 and is used to connect to the upper manifold 200 of the laminar flow cooling system. A first sliding member 122 has a first clearance through hole 122a, and the first sliding member 122 is sleeved on the outside of the slide rod 111 through the first clearance through hole 122a to be slidably connected with the slide rod 111.

The second column assembly 133 and the second inclined tie rod are connected to different parts of the second water collection component 131 so that the second water collection component 131 is evenly stressed and the stability of the second water collection box 130 structure is guaranteed.

[0096] In some embodiments, the second column assembly 133 and the second inclined column assembly 134 are arranged at an acute angle.

[0097] In some embodiments, the second column assembly 133 includes a third column 1331, a fourth column 1332, and a second column connector 1333. The third column 1331 and the fourth column 1332 are spaced apart along the Y direction.

[0100] like Figure 1 and Figure 3 As shown, in some embodiments, the mounting base 110 includes a slide rod 111 and a connecting assembly 112. The slide rod 111 is arranged along the X direction; the connecting assembly 112 is connected to the slide rod 111 and is used to connect to the upper manifold 200 of the laminar flow cooling system. The second sliding member 132 has a second clearance through hole 132a, and the second sliding member 132 is sleeved on the outside of the slide rod 111 through the second clearance through hole 132a to be slidably connected with the slide rod 111.

[0101] The shape of the second clearance through hole 132a is adapted to the shape of the cross section of the slide bar 111. In some embodiments, the cross section of the slide bar 111 is circular, and the second clearance through hole 132a is also circular.

[0102] In some embodiments, the first column assembly 123, the first inclined column assembly 124, the second column assembly 133, and the second inclined column assembly 134 are all located between two adjacent upper cooling manifolds 200.

[0103] The laminar cooling manifolds 200 are spaced apart, with a Y-axis spacing between adjacent laminar cooling manifolds 200. The first upright assembly 123, the first inclined column assembly 124, the second upright assembly 133, and the second inclined column assembly 134 are all located between adjacent laminar cooling manifolds 200, utilizing the Y-axis spacing between the laminar cooling manifolds 200. This helps to improve the compactness of the flow guiding device 100 and the laminar cooling manifolds 200, and improves space utilization.

[0104] The following is Figure 1 The working principle of the flow guiding device 100 is introduced by taking the structure shown as an example:

[0105] When the mounting base 110 of the flow guiding device 100 is connected to the laminar flow cooling upper manifold 200, the slide rod 111, the first column assembly 123, the first inclined column assembly 124, the second column assembly 133, and the second inclined column assembly 134 are all located between two adjacent laminar flow cooling upper manifolds 200. The two first flow guiding channels 120a are respectively located below the first side 210 of the two adjacent laminar flow cooling upper manifolds 200; the two second flow guiding channels 130a are respectively located below the second side 220 of the two adjacent laminar flow cooling upper manifolds 200. The upper layer of cold water from the first side 210 of the two laminar flow cooling upper manifolds 200 will fall into the first flow guiding channel 120a and flow along the first flow guiding channel 120a, and finally be discharged to the outside of the strip steel 400 through the first outlet 120b. The upper chilled water from the second side 220 of the two upper chilled manifolds 200 will fall into the two second guide channels 130a respectively, flow along the second guide channels 130a, and finally be discharged from the second outlet 130b to the outside of the strip 400. When the width of the processed strip 400 changes, the first water collection box 120 and the second water collection box 130 are manually pushed to move along the X direction, so that the first water collection box 120 and the second water collection box 130 move closer or further apart to adapt to the change in the width of the strip 400.

[0106] Based on the same inventive concept, this application also provides a strip cooling system, such as... Figure 6 As shown, it includes a roller conveyor 300, a laminar cooling upper manifold 200, and the aforementioned guide device 100. The roller conveyor 300 is used to transport the strip steel 400; the laminar cooling upper manifold 200 is disposed above the roller conveyor 300; the mounting base 110 of the guide device 100 is connected to the laminar cooling upper manifold 200.

[0107] It should be noted that, as Figure 6 As shown, multiple cooling upper manifolds 200 are typically arranged at intervals above the roller conveyor 300 along its length direction (Y direction), and the cooling upper manifolds 200 extend along the width direction (X direction) of the roller conveyor 300.

[0108] Since the strip cooling system includes the aforementioned flow guiding device 100, it naturally possesses all the beneficial effects of the flow guiding device 100, which will not be elaborated upon here.
