Detailed implementation manners

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0048] It should be noted that all the directional indications in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, the directional indication will also change accordingly.

[0049] In the present invention, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] In addition, in the present invention, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0051] The laminar cooling process in the hot strip rolling production line is a key process for controlling the tissue properties of strip steel products. Due to the characteristics of the three-way heat dissipation state at the strip edges during the rolling process, the temperature in the area about 100 mm from the strip edges is lower than that in the middle area of the strip before laminar cooling. In addition, during the laminar cooling process, since the cooling water is discharged from both sides, the cooling rate in the strip edge area is higher than that in the middle area of the strip, further exacerbating the temperature difference between the strip edge and the middle area, which has an adverse impact on the tissue properties of the strip and the uniformity of the internal stress distribution in the width direction. Therefore, defects such as edge cracks and edge waves often occur in the strip after the laminar cooling process.

[0052] In the related art, there are technical problems such as edge cracking and edge waves often occurring after the strip steel is cooled by laminar cooling. An embodiment of the present application provides a diversion device and a strip steel cooling system, which can at least to some extent solve the technical problems of edge cracking, edge waves and other defects often occurring after the strip steel is cooled by laminar cooling.

[0053] The diversion device 100 of the present application diverts the upper layer of cold water discharged from both sides of the laminar cooling upper header 200 to the outside of the strip steel 400 through the first water collecting box 120 and the second water collecting box 130, avoiding the upper layer of cold water discharged from both sides of the laminar cooling upper header 200 from falling on the edge of the strip steel 400, reducing the temperature drop at the edge of the strip steel 400, and thus improving problems such as edge cracking and edge waves of the strip steel.

[0054] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0055] The diversion device 100 is used to divert the upper layer of cold water discharged from the laminar cooling upper header 200. The laminar cooling upper header 200 has a first side 210 and a second side 220 that are oppositely arranged along the X direction, and a plurality of laminar cooling upper headers 200 are arranged at intervals along the Y direction, as Figure 10 shown.

[0056] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the diversion device 100 includes: a mounting seat 110, a first water collecting box 120 and a second water collecting box 130. The mounting seat 110 is connected to the laminar cooling upper header 200 and is located between two adjacent laminar cooling upper headers 200. The first water collecting box 120 is connected to the mounting seat 110. The first water collecting box 120 has a converging groove 120a and a drainage groove 120b that are communicated. The converging groove 120a is located below the first side 210; the drainage groove 120b extends along the X direction, and the drainage groove 120b is located below the mounting seat 110; the first liquid outlet 120c of the drainage groove 120b is arranged at one end of the drainage groove 120b away from the converging groove 120a. The second water collecting box 130 is connected to the mounting seat 110 and is arranged on the side of the drainage groove 120b away from the converging groove 120a. The second water collecting box 130 has a diversion groove 130a. The diversion groove 130a is arranged below the second side 220, and the second liquid outlet 130b of the diversion groove 130a is arranged on the side of the diversion groove 130a away from the converging groove 120a.

[0057] As Figure 10As shown, along the length direction of the roller table 300, a plurality of upper laminar cooling headers 200 are arranged at intervals above the roller table 300. The length direction of the upper laminar cooling headers 200 is parallel to the width direction of the roller table 300. When the strip steel 400 is subjected to laminar cooling, the strip steel 400 is located below the upper laminar cooling headers 200, and the strip steel 400 is transported through the roller table 300 below. The upper laminar cooling headers 200 spray upper layer cooling water downward, and the upper layer cooling water is sprayed on the upper surface of the strip steel 400.

[0058] In this application, the X direction is the width direction of the roller table 300 and also the length direction of the upper laminar cooling headers 200; the Y direction is the length direction of the roller table 300; the Z direction is the height direction.

[0059] During use, the mounting seat 110 is connected to both the upper laminar cooling headers 200 and the first water collecting box 120 and the second water collecting box 130. The mounting seat 110 bears the first water collecting box 120 and the second water collecting box 130, so that the first water collecting box 120 can be stably located below the first side 210 of the upper laminar cooling headers 200, and the second water collecting box 130 can be stably located below the second side 220 of the upper laminar cooling headers 200.

[0060] The connection manner of the mounting seat 110 with the upper laminar cooling headers 200, the first water collecting box 120, and the second water collecting box 130 is diverse, such as clamping connection, bolt connection, bundling connection, etc., which are not limited in this application. In some embodiments, the mounting seat 110 is connected to the cooling water beam of the upper laminar cooling headers 200.

[0061] The upper laminar cooling headers 200 are arranged at intervals, and there is a Y-direction interval between two adjacent upper laminar cooling headers 200. When the diversion device 100 is installed on the upper laminar cooling headers 200, the mounting seat 110 is located between two adjacent upper laminar cooling headers 200, making use of the Y-direction interval between the upper laminar cooling headers 200, which helps to improve the compactness of the diversion device 100 and the upper laminar cooling headers 200 and improve the space utilization rate.

[0062] The water collecting trough 120a is communicated with the water drainage trough 120b, and the first liquid outlet 120c of the water drainage trough 120b is arranged at one end of the water drainage trough 120b far from the water collecting trough 120a, so that the water collected in the water collecting trough 120a can enter the water drainage trough 120b and flow along the water drainage trough 120b and be discharged from one end of the water drainage trough 120b far from the water collecting trough 120a.

[0063] The water collecting trough 120a is located below the first side 210 of the upper laminar cooling headers 200, so that the water collecting trough 120a can collect the upper layer cooling water discharged from the first side 210.

[0064] The drainage groove 120b extends along the X direction and is located below the mounting seat 110, such that the drainage groove 120b is not located below the upper laminar cooling header 200, so as to prevent the upper cold water discharged from the middle region of each upper laminar cooling header 200 from interfering with the strip 400, ensuring that the upper cold water discharged from the middle region of the upper laminar cooling header 200 can smoothly fall onto the surface of the strip 400 to cool the strip 400.

[0065] The converging groove 120a is arranged below the first side 210 of the upper laminar cooling header 200, the drainage groove 120b is located below the mounting seat 110, and the first liquid outlet 120c of the drainage groove 120b is arranged at one end of the drainage groove 120b away from the converging groove 120a, which will cause: after the upper cold water discharged from the first side 210 of the upper laminar cooling header 200 enters the first water collecting box 120, it will be discharged from the first liquid outlet 120c located on the second side 220 of the upper laminar cooling header 200.

[0066] The guiding groove 130a is used to receive the upper cold water discharged from the second side 220 of the upper laminar cooling header 200 and guide and drain the upper cold water outside the strip 400. Specifically, the guiding groove 130a has a second liquid outlet 130b, and the upper cold water falling into the guiding groove 130a from the upper laminar cooling header 200 will be discharged outside the strip 400 through the second liquid outlet 130b.

[0067] After the guiding device 100 is designed as described above:

[0068] On the one hand, the upper cold water discharged from the first side 210 of the upper laminar cooling header 200 will fall into the converging groove 120a, enter the drainage groove 120b along the converging groove 120a, and be drained outside the strip 400 along the drainage groove 120b, avoiding falling on the edge of the strip 400; the upper cold water discharged from the second side 220 of the upper laminar cooling header 200 will fall into the guiding groove 130a and be drained outside the strip 400 along the guiding groove 130a, avoiding falling on the edge of the strip 400. The upper cold water on both sides of the upper laminar cooling header 200 is collected and drained outside the strip 400, and at the same time, problems such as edge cracks and edge waves caused by too fast cooling speed and uneven cooling on both sides of the strip 400 are improved, which helps to improve the quality of the strip 400.

[0069] On the other hand, the upper-layer cold water collected by the first water collecting box 120 from the first side 210 of the laminar cooling upper header 200 will be discharged from the first liquid outlet 120c located on the second side 220 of the laminar cooling upper header 200. The upper-layer cold water collected by the diversion groove 130a is also discharged from the second side 220. Through such a design, the operation side of the production line can be arranged on the first side 210, and the driving side of the production line can be arranged on the second side 220, avoiding water from falling on the operation side, facilitating the operator to observe the laminar cooling situation of the strip steel on the operation side, etc., ensuring the stable operation of the strip steel 400 production line, and the water flow is discharged from the second side, which is convenient for water collection.

[0070] In order to increase the flow rate of the water in the first water collecting box 120, in some embodiments, both the water collecting groove 120a and the water guiding groove 120b are inclined. The side of the water collecting groove 120a away from the water guiding groove 120b is high, and the side close to the water guiding groove 120b is low. The side of the water guiding groove 120b close to the water collecting groove 120a is high, and the side away from the water collecting groove 120a is low.

[0071] In order to increase the flow rate of the water in the second water collecting box 130, in some embodiments, the diversion groove 130a is inclined. The side of the diversion groove 130a away from the water guiding groove 120b is low, and the side close to the water guiding groove 120b is high.

[0072] In some embodiments, the first liquid outlet 120c and the second liquid outlet 130b have the same orientation, both facing away from the water collecting groove 120a, for the convenience of water collection.

[0073] As Figure 3 shown, in some embodiments, the water collecting groove 120a extends along the Y direction, and the water collecting groove 120a is simultaneously located below the first sides 210 of a plurality of laminar cooling upper headers 200, so that the water collecting groove 120a can simultaneously collect the upper-layer cold water discharged from the first sides 210 of a plurality of laminar cooling upper headers 200, without the need to provide a diversion device 100 on each laminar cooling upper header 200, which will help reduce the number of diversion devices 100 provided and save the production cost of the enterprise.

[0074] Figure 3 Figure 3 shown, in some embodiments, along the Y direction, the water guiding groove 120b is connected to the middle of the water collecting groove 120a. After such a design, the second water collecting box 130 is in a T shape. The water guiding groove 120b is arranged in the middle, so that the distances from both sides of the water collecting groove 120a along the Y direction to the water guiding groove 120b are quite equal, which helps to reduce the flow path of the cooling water and enables the cooling water to be quickly discharged.

[0075] The number of the diversion channels 130a can be one or multiple, which is not limited in this application. When one diversion channel 130a is provided, the diversion channel 130a can extend along the first direction to divert the upper-layer cold water discharged from one side of multiple diversion devices 100 simultaneously.

[0076] As Figure 4 shown, in some embodiments, the second water collecting box 130 has multiple diversion channels 130a. The multiple diversion channels 130a are arranged at intervals along the Y direction, and the multiple diversion channels 130a are arranged in one-to-one correspondence with the second sides 220 of the multiple upper-layer cooling headers 200.

[0077] The multiple diversion channels 130a are arranged in one-to-one correspondence with the second sides 220 of the multiple upper-layer cooling headers 200. That is to say, each diversion channel 130a is respectively located below each second side 220. After such a design, the second water collecting box 130 can collect the upper-layer cold water discharged from the second sides 220 of the multiple upper-layer cooling headers 200 simultaneously. Instead of arranging the diversion devices 100 on each upper-layer cooling header 200, this will help reduce the number of the diversion devices 100 arranged and save the production cost of the enterprise.

[0078] In some embodiments, the second water collecting box 130 includes a second box body 131 and a second sliding member 132. The second box body 131 has the diversion channel 130a, and the second sliding member 132 is connected to the mounting seat 110 and the second box body 131.

[0079] In some embodiments, the second water collecting box 130 includes multiple second box bodies 131. Each second box body 131 is provided with one diversion channel 130a, and the second sliding member 132 connects the multiple second box bodies 131 together.

[0080] In some embodiments, one side of the drainage channel 120b away from the confluence trough 120a is located between two adjacent diversion channels 130a.

[0081] The multiple diversion channels 130a are arranged at intervals along the Y direction. Therefore, there is a Y-direction interval between two adjacent diversion channels 130a. One end of the drainage channel 120b away from the confluence trough 120a is located in the Y-direction interval, making use of the Y-direction interval between the diversion channels 130a. This helps improve the compactness of the structure of the diversion device 100 and reduces the space occupied by the diversion device 100.

[0082] In some embodiments, the diversion device 100 diverts the flow for two upper laminar cooling headers 200 simultaneously. The second water collecting box 130 includes two second box bodies 131. The second sliding member 132 is located between the two second box bodies 131 and is connected to the two second box bodies 131. The two second box bodies 131 are respectively located below the two second sides 220. The side of the drainage groove 120b away from the confluence groove 120a is located between the two second box bodies 131. The confluence groove 120a is simultaneously located below the two first sides 210, and along the X direction, the confluence groove 120a and the second water collecting box 130 are opposite to each other.

[0083] In some embodiments, along the Y direction, a plurality of diversion grooves 130a are symmetrically arranged along the drainage groove 120b.

[0084] In some embodiments, along the X direction, both the first water collecting box 120 and the second water collecting box 130 are slidably connected to the mounting seat 110.

[0085] After such a design, the first water collecting box 120 and the second water collecting box 130 can move along the X direction, so that the positions of the confluence groove 120a and the diversion grooves 130a can be adaptively changed according to the position of the edge of the strip steel 400, adapting to strip steels 400 of different widths, which facilitates the use of the diversion device 100.

[0086] As Figure 2 shown, in some embodiments, the mounting seat 110 includes: a fixed frame 111, a sliding frame 112, and a connecting beam 113. The fixed frame 111 is located above the sliding frame 112. The fixed frame 111 is used to connect to the upper laminar cooling header 200. Both the first water collecting box 120 and the second water collecting box 130 are slidably connected to the sliding frame 112. The drainage groove 120b is arranged below the sliding frame 112. The connecting beam 113 is connected to the fixed frame 111 and the sliding frame 112.

[0087] The connecting member 141 is connected to both the fixed frame 111 and the sliding frame 112, fixedly connecting the fixed frame 111 and the sliding frame 112 together; the mounting seat 110 is connected to the upper laminar cooling header 200 through the fixed frame 111 and is slidably connected to the first water collecting box 120 and the second water collecting box 130 through the sliding frame 112. This design adopts a modular assembly method, disassembling the overall structure into three independently processed components (fixed frame 111, sliding frame 112, connecting beam 113), which not only reduces the processing complexity but also realizes functional partitioning. This clearly divided structural design not only facilitates production and assembly but also provides a flexible component replacement solution for later maintenance, contributing to improving the maintainability and expandability of the mounting seat 110.

[0088] The number of the connecting beams 113 can be one or more, which is not limited in this application.

[0089] As Figure 3 、Figure 5 , Figure 6 and Figure 7 As shown in Figure 5 , Figure 6 and Figure 7 , in some embodiments, the first water collecting box 120 includes a first box body 121 and a plurality of first sliding members 122. The first box body 121 has a confluence groove 120a and a drainage groove 120b.

[0094] The second sliding member 132 and the second box body 131 can be connected by means such as welding, snap connection, bolt connection, etc., which are not limited in this application. The connection method between the second sliding member 132 and the sliding frame 112 is diverse.

[0096] In some embodiments, such as Figure 2 shown, the fixing frame 111 is formed by connecting four angle steels.

[0097] During the production process of the strip steel 400, when the strip steel 400 takes off or forms an arch, there is a risk of hitting the edge flow guiding device 100. As Figure 1 , Figure 8 and Figure 9 shown, in some embodiments, the flow guiding device 100 further includes an anti-collision component 140 installed on the sliding frame 112 and / or the fixing frame 111. At least a part of the anti-collision component 140 is located below the first water collecting box 120, and the lowest point of the anti-collision component 140 is lower than the lowest points of the first water collecting box 120 and the second water collecting box 130.

[0098] The anti-collision assembly 140 can be connected to the sliding frame 112, or to the fixed frame 111, or simultaneously connected to both the sliding frame 112 and the fixed frame 111. It should be noted that the lowest point of the anti-collision assembly 140 is lower than the lowest point of the first water collecting box 120 and also lower than the lowest point of the second water collecting box 130. After the anti-collision assembly 140 is provided, when the strip steel 400 flies up and forms an arch, the strip steel 400 impacts the anti-collision assembly 140, avoiding the impact on the first water collecting box 120 and the second water collecting box 130, providing protection for the first water collecting box 120 and the second water collecting box 130, and contributing to ensuring the stable operation of the diversion device 100.

[0099] As Figure 8 shown, in some embodiments, the anti-collision assembly 140 includes an anti-collision member 142 and two connecting members 141. The two connecting members 141 are both connected to the sliding frame 112 and / or the fixed frame 111, and along the Y direction, the two connecting members 141 are respectively located on both sides of the sliding frame 112. The anti-collision member 142 is arranged below the drainage groove 120b and connected to the two connecting members 141. The lowest point of the anti-collision member 142 is lower than the lowest point of the first water collecting box 120 and the lowest point of the second water collecting box 130.

[0100] The connecting member 141 can be connected to the sliding frame 112, or to the fixed frame 111, or simultaneously connected to both the sliding frame 112 and the fixed frame 111. One side of the anti-collision member 142 is connected to one of the connecting members 141, and the other side is connected to the other connecting member 141. The lowest point of the anti-collision member 142 is lower than the lowest point of the first water collecting box 120 and also lower than the lowest point of the second water collecting box 130. When the strip steel 400 flies up and forms an arch, the strip steel 400 impacts the anti-collision member 142, avoiding the impact on the first water collecting box 120 and the second water collecting box 130.

[0101] In some embodiments, the anti-collision member 142 is coated with a buffer member, and the buffer member can be made of materials such as silica gel, rubber, sponge, etc. to reduce the impact force of the strip steel 400.

The guiding surface 142a is connected to the lower end surface 142b of the anti-collision member 142. The guiding surface 142a is inclined, with the side closer to the connecting member 141 being higher and the side closer to the lower end surface 142b being lower. The guiding surface 142a can guide the strip 400 so that when the strip 400 flies up and forms an arch, it contacts the lower end surface 142b. In these embodiments, the lower end surface 142b is lower than the lowest point of the first water collecting box 120 and also lower than the lowest point of the second water collecting box 130.

[0105] In some embodiments, two guiding surfaces 142a are provided on the anti-collision member 142. Along the Y direction, the two guiding surfaces 142a are respectively located on both sides of the lower end surface 142b.

[0106] The following takes Figure 1 the structure shown as an example to introduce the working principle of the diversion device 100:

[0107] When the mounting seat 110 of the diversion device 100 is connected to the upper laminar cooling header 200, the mounting seat 110 is located between two adjacent upper laminar cooling headers 200. The water collecting trough 120a is simultaneously located below the first side 210 of two adjacent upper laminar cooling headers 200; the two diversion troughs 130a are respectively located below the second side 220 of two adjacent upper laminar cooling headers 200. The upper cold water on the first side 210 of the two upper laminar cooling headers 200 will fall into the water collecting trough 120a and flow along the water collecting trough 120a into the drainage trough 120b, and finally be discharged to the outside of the strip 400 through the first liquid outlet 120c of the drainage trough 120b. The upper cold water on the second side 220 of the two upper laminar cooling headers 200 will respectively fall into the two diversion troughs 130a and finally be discharged to the outside of the strip 400 through the second liquid outlets 130b of the diversion troughs 130a. When the width of the strip 400 being processed changes, the first water collecting box 120 and the second water collecting box 130 are manually pushed so that the first water collecting box 120 and the second water collecting box 130 approach or move away from each other to adapt to the change in the width of the strip 400. When the strip 400 flies up and forms an arch, the strip 400 impacts the anti-collision member 142, avoiding impacting the first water collecting box 120 and the second water collecting box 130.

[0108] Based on the same inventive concept, the embodiment of the present application also provides a strip cooling system, as Figure 10 shown, including a roller table 300, an upper laminar cooling header 200 and the above-mentioned diversion device 100. The roller table 300 is used for transporting the strip 400; the upper laminar cooling header 200 is arranged above the roller table 300; the mounting seat 110 of the diversion device 100 is connected to the upper laminar cooling header 200 and is located between two adjacent upper laminar cooling headers 200.

[0109] It should be noted that, as Figure 10As shown, a plurality of upper laminar cooling headers 200 are generally arranged at intervals along the length direction (Y direction) of the roller table 300 above the roller table 300, and the upper laminar cooling headers 200 extend along the width direction (X direction) of the roller table 300. The mounting seat 110 is located between two adjacent upper laminar cooling headers 200 and is fixedly connected to the upper laminar cooling headers 200.

[0110] Since the strip cooling system includes the above-mentioned diversion device 100, it naturally has all the beneficial effects of the diversion device 100, which will not be elaborated here.
