Detailed Embodiments

[0031] In order to make those skilled in the art in the technical field to which the present application belongs understand the present application more clearly, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0032] In the first aspect embodiment of the present application, a hot-rolled strip coiling device is provided, which can remove the cooling water on the surface of the cooled hot-rolled strip, thereby reducing the risk of corrosion of the hot-rolled strip and the frame of the coiling component.

[0033] Please refer to Figure 1, The hot-rolled strip coiling device includes a conveying assembly 10, a coiling assembly 50, a cooling assembly 20 and an air-drying assembly 40. The conveying assembly 10 is used to convey the hot-rolled strip. The coiling assembly 50 is located on the output side of the conveying assembly 10 to coil the hot-rolled strip conveyed by the conveying assembly 10. The cooling assembly 20 is provided with a plurality of nozzles 22, and the plurality of nozzles 22 are arranged in sequence along the width direction of the hot-rolled strip to spray cooling water onto the hot-rolled strip. The water-sweeping assembly 30 is provided with a plurality of water-sweeping brushes 31, and the plurality of water-sweeping brushes 31 are arranged in sequence along the width direction of the hot-rolled strip to clean the cooling water on the surface of the hot-rolled strip. The air-drying assembly 40 is provided with a plurality of air outlets 43 facing the hot-rolled strip to blow air onto the hot-rolled strip;

[0034] Since the nozzles 22, the water-sweeping brushes 31 and the air outlets 43 are all located above the conveying assembly 10 and are arranged in sequence along the running direction of the hot-rolled strip, therefore, during the running process of the hot-rolled strip, the cooling water sprayed by the nozzles 22 first cools the hot-rolled strip, then the residual water on the upper surface of the hot-rolled strip is cleaned by the water-sweeping brushes 31, and then the water marks on the surface of the hot-rolled strip are further air-dried by the air blown out from the air outlets 43. Finally, it is coiled by the coiling assembly 50. In this way, there is no cooling water on the surface of the coiled hot-rolled strip, which reduces the risk of corrosion of the hot-rolled strip. At the same time, it also avoids the hot-rolled strip from bringing the cooling water to the coiling assembly, solving the problem of corrosion of the frame of the coiling assembly.

[0035] In some embodiments, the water-sweeping brush 31 can be a flexible brush, such as a plastic brush. The flexible brush contacts the conveying assembly 10. In this way, during the process that the hot-rolled strip passes between the flexible brush and the conveying assembly 10, the flexible brush will produce slight deformation and act on the upper surface of the hot-rolled strip, and thoroughly clean the residual water. In addition, the setting of the flexible brush can also avoid defects such as scratches on the surface of the hot-rolled strip. In other embodiments, the water-sweeping brush 31 can also be a rigid brush, which can also achieve the cleaning of the residual water on the surface of the hot-rolled strip.

[0036] In some embodiments, the water-sweeping brush 31 is arranged along the width direction of the hot-rolled strip and extends out of both sides of the width direction of the hot-rolled strip to clean the residual water in the entire width direction of the hot-rolled strip, improving the cleaning effect of the residual water on the hot-rolled strip. In other embodiments, the extending direction of the water-sweeping brush 31 can also have an included angle with the width direction of the hot-rolled strip, which can also achieve the cleaning of the residual water on the hot-rolled strip.

[0037] In certain embodiments, please refer to Figure 1 , the water-sweeping assembly 30 can include a water-sweeping plate 32. The water-sweeping plate 32 serves as a support structure, and the water-sweeping brush 31 is installed on the water-sweeping plate 32. In other embodiments, the water-sweeping plate 32 can also be replaced by a water-sweeping block or a water-sweeping bracket 44, which can still provide an installation basis for the water-sweeping brush 31.

[0038] Please refer to Figure 1 andFigure 2 , the air drying assembly 40 includes an air duct 41, a fan 42, and a bracket 44. One end of the air duct 41 is open, and the other end is closed. The air duct 41 is provided with a plurality of air outlets 43. The fan 42 is installed at one end of the air duct 41, and the air duct 41 is installed on the bracket 44. The bracket 44 can support the air duct 41 as an installation base. The fan 42 is installed on the open side of the air duct 41, which can introduce external air into the air duct 41. Since the other end of the air duct 41 is closed, the air can only be discharged through the air outlets 43 and blown onto the hot-rolled strip to dry the water marks on the upper surface of the hot-rolled strip. In some other embodiments, there can also be two fans 42. Both ends of the air duct 41 are open, and the two fans 42 are located at the openings at both ends of the air duct 41, which can also introduce air into the air outlets 43 and blow onto the upper surface of the hot-rolled strip.

[0039] The number of the air outlets 43 can be three, ten, or eighteen. The size of the air outlets 43, the distance between adjacent two air outlets 43, and the distance between the air duct 41 and the hot-rolled strip can all be adjusted according to the air drying requirements, which will not be elaborated here.

[0040] In some embodiments, the air duct 41 can extend along the width direction of the hot-rolled strip, or can have an angle with the width direction of the hot-rolled strip. Of course, the number of the air ducts 41 can also be set to multiple, such as two or three. Multiple air ducts 41 can be arranged in sequence along the running direction of the hot-rolled strip.

[0041] In some embodiments, please refer to Figure 1 , the bracket 44 can also be connected to the water sweeping plate 32 of the water sweeping assembly 30. Therefore, the water sweeping assembly 30 and the air drying assembly 40 share the same bracket 44, making the structure simpler. In some other embodiments, there can also be two brackets 44. One bracket 44 installs the air duct 41, and the other bracket 44 installs the water sweeping plate 32, which can also realize the installation of the water sweeping assembly 30 and the air drying assembly 40.

[0042] In some embodiments, please refer to Figure 1 , both the water sweeping brush 31 and the air outlets 43 are close to the output side of the conveying assembly 10, which can extend the cooling time of the hot-rolled strip and improve the cooling effect. In some other embodiments, the water sweeping brush 31 and the air outlets 43 can also be located in the middle of the conveying assembly 10, which can also realize the cooling, water sweeping, and air drying of the hot-rolled strip.

[0043] In some embodiments, please continue to refer to Figure 1 , the water sweeping brush 31 and the air outlets 43 are close to each other, making the structure more compact and facilitating maintenance. In other embodiments, the water sweeping brush 31 and the air outlets 43 can also be far from each other, which can also realize the water sweeping and air drying of the hot-rolled strip.

[0044] The conveying assembly 10 serves as the conveying structure for hot-rolled strip steel. In some embodiments, the conveying assembly 10 is a conveyor belt 11 assembly, and the hot-rolled strip steel is conveyed through the conveyor belt 11 assembly, which has low cost. In other embodiments, the conveying assembly 10 can also be a conveying roller assembly, which can also achieve the conveying of hot-rolled strip steel.

[0045] In some embodiments, referring to Figure 1 , the conveyor belt 11 assembly includes a conveying driving member 12, rollers 13, and a conveyor belt 11. There are two rollers 13, and the two rollers 13 are arranged opposite to each other along the running direction of the hot-rolled strip steel. The conveying driving member 12, that is, the conveying motor, is force-transmittingly connected to one of the rollers 13. The conveyor belt 11 is a closed loop, and the two rollers 13 are located inside the closed loop. When the conveying motor rotates, it can drive one of the rollers 13 to rotate, and drive the other roller 13 to rotate through the conveyor belt 11. The hot-rolled strip steel runs towards the coiling assembly 50 under the drive of the conveyor belt 11.

[0046] In some embodiments, the conveying driving member 12 of the conveyor belt 11 assembly is close to the coiling assembly 50, that is, the conveying driving member 12 is force-transmittingly connected to the roller 13 close to the coiling assembly 50. In other embodiments, the conveying driving member 12 can also be far from the coiling assembly 50, and it can also achieve the conveying of hot-rolled strip steel.

[0047] The cooling assembly 20 is used to cool the hot-rolled strip steel. In some embodiments, referring to Figure 1 and Figure 3 , the cooling assembly 20 includes a water tank 23, cooling pipes 21, and a cooling driving member 24. Among them, the water tank 23 includes a heat dissipation cover plate 231 with a water passing hole 232. The water tank 23 is located between the upper and lower layers of the conveyor belt 11, so that the cooling water falls onto the heat dissipation cover plate 231 through the strip steel to dissipate heat and cool down, and then enters the water tank 23 through the water passing hole 232 for storage. One end of the cooling pipe 21 is closed, and the other end has an opening. One end of the cooling driving member 24 is connected to the water tank 23, and the other end is connected to the opening of the cooling pipe 21, and can send the cooling water in the water tank 23 into the cooling pipe 21. The spray head 22 is installed on the cooling pipe 21, and the cooling water in the cooling pipe 21 is sprayed onto the upper surface of the hot-rolled strip steel through the spray head 22 to cool the hot-rolled strip steel.

[0048] In some embodiments, the heat dissipation cover plate 231 extends out of both sides in the width direction of the upper layer of the conveyor belt 11 assembly, so that most of the cooling water flowing down from both sides in the width direction of the hot-rolled strip steel can fall onto the heat dissipation cover plate 231, improving the recovery effect of the cooling water.

[0049] In some embodiments, the heat dissipation cover plate 231 can be set to a structure with a high perimeter and a low middle part, which is convenient for the cooling water to flow towards the middle part of the heat dissipation cover plate 231 under the action of gravity, further improving the recovery effect of the cooling water.

[0050] The coiling assembly 50 is used to coil the hot-rolled steel strip after air drying. Figure 1 The winding assembly 50 includes a winding drive 51, a winding roller 52, and a pressure roller 53. The winding drive 51 is connected to the winding roller 52 by transmission, and the pressure roller 53 is located above the winding roller 52. Under the action of the winding drive 51, that is, the winding motor, the winding roller 52 rotates, so that the strip is wound around the winding roller 52. The pressure roller 53 is located above the winding roller 52, which facilitates the insertion of the head of the hot-rolled strip into the gap between the pressure roller 53 and the winding roller 52, thereby improving the winding efficiency. The winding assembly 50 is prior art. For more information, please refer to the prior art disclosures, and this application will not elaborate on it.

[0051] Please continue reading Figure 1 The hot-rolled strip coiling device also includes a frame 60 and a stabilizing block 71. The frame 60 is the installation base. The conveying assembly 10, the coiling assembly 50, the cooling assembly 20, the water sweeping assembly 30 and the air drying assembly 40 are all installed on the frame 60. In a specific implementation, the conveying drive 12 of the conveying assembly 10 is installed on the frame 60, the coiling drive 51 of the coiling assembly 50 is installed on the frame 60, the box of the cooling assembly 20 is installed on the frame 60, and the bracket 44 of the water sweeping assembly 30 is installed on the frame 60, thereby realizing the installation of each structure. There are multiple stabilizing blocks 71, such as four, eight or ten. The multiple stabilizing blocks 71 are distributed in a non-linear manner, such as a matrix distribution or a triangular distribution. The stabilizing blocks 71 are connected to the frame 60 through the mounting blocks 72. The stabilizing blocks 71 are in contact with the ground, and there is friction between the two, thereby improving the stability of the hot-rolled strip coiling device during operation.

[0052] In a specific embodiment, the stabilizing block 71 is detachably connected to the mounting block 72 , for example, by screwing or welding, etc. Similarly, the mounting block 72 is detachably connected to the frame 60 , for example, by screwing or welding, etc.

[0053] The present application ensures that the surface of the hot-rolled strip is dry by arranging a water sweeping assembly 30 and an air drying assembly 40 between the cooling assembly 20 and the coiling assembly 50, thereby reducing the risk of corrosion of the hot-rolled strip. At the same time, it also avoids the hot-rolled strip from bringing cooling water to the coiling assembly, thereby solving the problem of corrosion of the coiling assembly frame.
