Description

Technical Field

[0001] This invention relates to the field of roughing mill de-rolling technology, and more specifically to a de-rolling roller structure for steel rolling production with alternating cooling. Background Technology

[0002] High-carbon steel, due to its high carbon and alloy element content, requires higher quality control of continuously cast billets. Defects such as porosity, shrinkage cavities, and cracks often occur inside the billets due to the influence of casting speed, pouring temperature, and cooling intensity. These discontinuous defects inside the steel have no corresponding pattern. After being rolled into round steel, some of them are fused together between the hot-deformed metal atoms, while others may not be able to be fused together. In particular, large-size high-carbon round steel has many residual defects, which affects the use by downstream customers.

[0003] Chinese patent CN217990420U discloses a novel roller conveyor for transporting rolled steel, comprising a roller conveyor frame, a first toothed disc, and a bearing column. A roller assembly is mounted on the inner side of the roller conveyor frame, and a rack is fixed to the lower side of the frame, with the rack slidably connected to the support column. However, this device still has the following problems during use:

[0004] The equipment uses a single-row roller conveyor. When the rough-rolled material moves onto the roller conveyor, it needs to be cooled down. At this time, it is necessary to wait for the material temperature to drop before the finishing rolling operation can be carried out. Only then can the next rough-rolled material be transported, resulting in low production efficiency.

[0005] Based on this, the present invention designs a de-rolling roller structure for steel rolling production with alternating cooling to solve the above problems. Summary of the Invention

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0041] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-11 A roll conveyor structure for steel rolling production with alternating cooling includes a base plate 1, a multi-station alternating transport mechanism 2, an adaptive adjustment material transfer mechanism 3, a roll cooling mechanism 4, a synchronous cleaning mechanism 5, and a mounting frame 6. The middle left side of the base plate 1 is set as the loading station, and the middle right side of the base plate 1 is set as the unloading station. The front and rear sides of the base plate 1 are set as cooling stations.

[0042] The upper end of the base plate 1 is equipped with a multi-station alternating transport mechanism 2 for controlling the two mounting frames 6 to move alternately to the loading station and the cooling station; the two mounting frames 6 are installed on the front and rear sides of the multi-station alternating transport mechanism 2; the mounting frames 6 are equipped with an adaptive adjustment transfer mechanism 3 for transferring the rolled steel from the loading station to the unloading station; the adaptive adjustment transfer mechanism 3 includes a first drive assembly 31, a second drive assembly 32 and a reset assembly 33, multiple sets of first drive assemblies 31 and second drive assemblies 32 are staggered on the mounting frames 6, and the second drive assembly 32 is also equipped with a reset assembly 33 to prevent slippage during the transport of bent rolled steel;

[0043] A roller cooling mechanism 4 is installed on the base plate 1, mounting bracket 6, first drive assembly 31, and second drive assembly 32 to automatically adjust the flow rate of the cooling medium and reduce damage to the first drive assembly 31 and second drive assembly 32 at the loading station caused by high-temperature rolling. The roller cooling mechanism 4 includes an input main pipe 41, a three-way housing 42, a first cooling assembly, a second cooling assembly, a first control assembly, a second control assembly, and a reversing assembly. The three-way housing 42 is fixedly installed on the upper left middle part of the base plate 1, and the input main pipe 41 is fixedly provided at the left feed port of the three-way housing 42. The discharge ports on the front and rear sides of the right side are respectively connected to the first cooling component and the second cooling component; a reversing component for controlling the flow direction and flow rate of the input main pipe 41 is also installed on the three-way housing 42; the first cooling component is connected to the first drive component 31, the second drive component 32 and the reset component 33 on the front mounting bracket 6; the second cooling component is connected to the first drive component 31, the second drive component 32 and the reset component 33 on the rear mounting bracket 6; the outside of the input main pipe 41 is connected to the pump body; the first control component is connected to the front mounting bracket 6 and the second control component is connected to the rear mounting bracket 6;

[0044] The first and second cooling components have the same structure and function, only their installation positions are different.

[0045] The first and second control components have the same structure and function, only their installation locations are different.

[0046] The mounting bracket 6 is also equipped with a synchronous cleaning mechanism 5 for controlling the first drive component 31 and the second drive component 32 to achieve self-cleaning when they are working.

[0047] In this invention, the rough-rolled steel enters the loading station from the left side of the base plate 1. At this time, the front mounting frame 6 is in the loading station. Then, the first drive assembly 31 and the second drive assembly 32 on the front mounting frame 6 work to drive the steel to move to the right. During the steel conveying process, if the steel has a slight upward bending deformation at a certain position, the reset assembly 33 will work to make the second drive assembly 32 fully fit with the bent steel surface, preventing the steel from slipping during the conveying process. After the steel is completely moved to the front mounting frame 6 in the loading station, the multi-station alternating transport mechanism 2 works to push the two mounting frames 6 forward at the same time until the front mounting frame 6 drives the steel to move to the cooling station in front of the base plate 1 for cooling. The rear mounting frame 6 moves from the cooling station in the rear of the base plate 1 to the loading station.

[0048] Subsequently, the next rough-rolled steel enters the loading station from the left side of the base plate 1 and moves to the rear mounting frame 6 via the first drive assembly 31 and the second drive assembly 32 on the loading station mounting frame 6. Then, the multi-station alternating transport mechanism 2 drives the two mounting frames 6 to move backward simultaneously. At this time, the mounting frame 6 at the cooling station on the front side of the base plate 1 returns to the loading station, while the mounting frame 6 at the loading station returns to the cooling station on the rear side of the base plate 1 for cooling of the rolled steel. At this time, the first drive assembly 31 and the second drive assembly 32 on the front mounting frame 6 at the loading station continue to work, driving the cooled rolled steel to the right and entering the finishing rolling process via the unloading station on the right side of the base plate 1. At the same time, the next rough-rolled steel enters the mounting frame 6 from the loading station on the left side of the base plate 1 until the rolled steel moves to the front mounting frame 6 via the first drive assembly 31 and the second drive assembly 32. Then, the above operation is repeated, which can achieve sufficient cooling of the rolled steel without affecting the steel rolling production process, thereby improving the production efficiency of steel rolling.

[0049] The synchronous cleaning mechanism 5 enables the first drive component 31 and the second drive component 32 to achieve automatic cleaning during operation, reducing the extra workload of manual cleaning in the later stage.

[0050] Because the temperature of the rolled steel is high after rough rolling, long-term transportation will cause damage to the first drive assembly 31 and the second drive assembly 32. At this time, the cooling medium flows into the three-way housing 42 through the input main pipe 41, and then flows through the first cooling assembly and the second cooling assembly to the first drive assembly 31 and the second drive assembly 32 on the front and rear mounting brackets 6 respectively. Finally, the cooling medium is discharged through the first cooling assembly and the second cooling assembly, realizing the heat exchange between the first drive assembly 31 and the second drive assembly 32.

[0051] When the multi-station alternating transport mechanism 2 operates and drives the front mounting frame 6 to move to the loading station, the first control component on the front mounting frame 6 controls the reversing component to operate, causing the cooling medium flowing out of the input main pipe 41 to deviate towards the first cooling component, increasing the speed of the cooling medium passing through the first cooling component and decreasing the speed of the cooling medium passing through the second cooling component. This increases the heat exchange efficiency of the first drive component 31 and the second drive component 32 at the loading station, reduces the damage to the first drive component 31 and the second drive component 32 at the loading station caused by high-temperature steel rolling, and extends the service life of the device.

[0052] Example 2: In some embodiments, such as Figures 1-10 As shown, in a preferred embodiment of the present invention, the multi-station alternating transport mechanism 2 includes a push cylinder 21, a guide rail 22, and a sliding block 23. Two push cylinders 21 are symmetrically fixedly installed on the upper rear side of the base plate 1, and two guide rails 22 are symmetrically fixedly installed on the upper left and right sides of the base plate 1.

The output end of the push cylinder 21 is fixedly connected to the rear end of the mounting bracket 6 on the rear side.

[0053] The first drive assembly 31 includes a first motor 311 and a planar rotating roller 312. Multiple first motors 311 are fixedly mounted on the upper outer side of the mounting frame 6, and the front and rear ends of the planar rotating roller 312 are rotatably mounted on the upper middle part of the mounting frame 6; and the output end of the first motor 311 is fixedly connected to the planar rotating roller 312.

[0054] The second drive assembly 32 includes a second motor 321 and a convex roller 322. Multiple second motors 321 are fixedly mounted on the outer side of the upper end of the mounting frame 6. The output end of the second motor 321 is connected to the reset assembly 33. The convex roller 322 is also connected to the reset assembly 33.

[0055] The first motor 311 and the second motor 321 are arranged alternately; the planar roller 312 and the convex roller 322 are hollow inside.

[0056] The reset assembly 33 includes a universal coupling 331, a clearance groove 332, a moving plate 333, a reset pin 334, and a reset spring 335. One side of the universal coupling 331 is fixedly connected to the output end of the second motor 321, and the other side of the universal coupling 331 is fixedly connected to one end of the convex roller 322. The upper middle part of the mounting bracket 6 is also symmetrically provided with clearance grooves 332 on both the front and rear sides. The front and rear ends of the convex roller 322 are limited and slidably connected to the clearance grooves 332.

[0057] The front and rear ends of the convex roller 322 are also rotatably mounted with movable plates 333; the lower end of the movable plate 333 is fixedly mounted with two reset pins 334, and the reset pins 334 are slidably connected to the upper end of the mounting frame 6; the reset spring 335 is wound around the outer end of the reset pins 334, and the upper end of the reset spring 335 is fixedly connected to the movable plate 333, and the lower end of the reset spring 335 is fixedly connected to the mounting frame 6.

[0058] Both the first and second cooling components include an input main pipe 45, input branch pipes 46, a sealing cover 47, an output branch pipe 48, and an output main pipe 49. The left end of the input main pipe 45 of the first cooling component is fixedly connected to the discharge port on the right front side of the tee housing 42; the left end of the input main pipe 45 of the second cooling component is fixedly connected to the discharge port on the right rear side of the tee housing 42; the left section of the input main pipe 45 is configured as a flexible hose, and the middle and right sections of the input main pipes 45 of both the first and second cooling components are configured as rigid pipes, and are fixedly installed on the upper end of the mounting frame 6 by a support frame; one end of each of the multiple input branch pipes 46 is fixedly connected to the input main pipe 45; the output main pipe 49 is fixedly installed on the upper end of the mounting frame 6 by a support frame, and one end of each of the multiple output branch pipes 48 is fixedly connected to the output main pipe 49.

[0059] Each of the two mounting brackets 6 has a sealing cover 47 rotatably mounted on one end of the flat roller 312 and the convex roller 322 that are close to each other. The sealing covers 47 on the front and rear sides are provided with slots at the ends of the two sides that are close to each other, and the lower end of the sealing cover 47 is provided with an outlet. The other end of the output branch pipe 48 is connected to the outlet of the sealing cover 47. The other end of the input branch pipe 46 passes through the slot and is rotatably connected to the inner wall of the flat roller 312 and the convex roller 322 that are far apart from each other on the two mounting brackets 6.

[0060] The input branch pipe 46 is also provided with multiple spray holes;

[0061] The planar roller 312 and the convex roller 322 are connected to the sealing cover 47; the outer end of the main output pipeline 49 is connected to the collection container.

[0062] The portion of the input branch pipe 46 located inside the flat roller 312 or the convex roller 322 is a rigid pipe, while the portion of the input branch pipe 46 located outside the sealing cover 47 is a flexible pipe.

[0063] The output branch pipe 48 is a flexible hose;

[0064] Both the first control component and the second control component include an L-shaped push rod 410 and a roller 411. The L-shaped push rod 410 of the first control component is fixedly installed on the left end of the front mounting bracket 6, and the L-shaped push rod 410 of the second control component is fixedly installed on the left end of the rear mounting bracket 6. The roller 411 is also rotatably provided at the end of the two L-shaped push rods 410 that are close to each other.

[0065] The reversing assembly includes an adjusting baffle 43 and a driving rotating plate 44. The adjusting baffle 43 is rotatably disposed in the middle of the three-way housing 42, and the driving rotating plate 44 is rotatably mounted in the middle of the upper end of the three-way housing 42. The adjusting baffle 43 and the driving rotating plate 44 are fixedly connected.

[0066] In this invention, the rough-rolled steel enters the loading station from the left side of the base plate 1. At this time, the front mounting frame 6 is in the loading station. Subsequently, the first motor 311 and the second motor 321 on the front mounting frame 6 operate to drive the flat roller 312 and the convex roller 322 to rotate, causing the steel to move to the right. During the steel conveying process, after the lower end of the steel touches the upper end of the convex roller 322, it will press down on the convex roller 322, causing the front and rear ends of the convex roller 322 to slide downward along the relief groove 332. The convex roller 322 will also drive the moving plate 333 to move downward together. 33 drives the reset pin 334 to move downwards, at which time the moving plate 333 will continuously compress the reset spring 335 downwards; the movement of the moving plate 333 drives the coupling connected to the universal coupling 331 to move downwards together; so that the surface of the convex roller 322 is in contact with the rolled steel. If there is a slight upward bending deformation at a certain position of the rolled steel, the reset spring 335 resets and drives the reset pin 334 to push the moving plate 333 upwards. At this time, the moving plate 333 will drive the convex roller 322 to reset upwards until the upper end of the convex roller 322 is fully in contact with the bent part of the rolled steel, so as to prevent the rolled steel from slipping during the conveying process;

[0067] After the rolled steel is completely moved to the front mounting frame 6 at the loading station, the push cylinder 21 works to push the two mounting frames 6 to move forward along the guide rail 22 along with the sliding block 23 until the front mounting frame 6 drives the rolled steel to the cooling station at the front of the bottom plate 1 for cooling, and the rear mounting frame 6 moves from the cooling station at the rear of the bottom plate 1 to the loading station.

[0068] Subsequently, the next rough-rolled steel enters the loading station from the left side of the base plate 1, and the first motor 311 and the second motor 321 on the loading station mounting frame 6 drive the flat roller 312 and the convex roller 322 to rotate, so that the steel moves to the mounting frame 6 on the rear side.

[0069] Subsequently, the push cylinder 21 operates, causing both mounting frames 6 to move backward simultaneously. At this time, the mounting frame 6 located at the cooling station on the front side of the base plate 1 returns to the loading station, while the mounting frame 6 located at the loading station returns to the cooling station on the rear side of the base plate 1 for cooling of the rolled steel. At this time, the flat roller 312 and convex roller 322 on the front mounting frame 6 located at the loading station resume rotation, driving the cooled rolled steel to the right and entering the finishing rolling process through the unloading station on the right side of the base plate 1. At the same time, the next rough-rolled steel then enters the mounting frame 6 from the loading station on the left side of the base plate 1 until the rolled steel moves to the front mounting frame 6 through the flat roller 312 and convex roller 322. The above operation is then repeated, which can achieve sufficient cooling of the rolled steel without affecting the steel rolling production process, thereby improving the production efficiency of steel rolling.

[0070] Because the rolled steel is at a high temperature after rough rolling, prolonged transportation can cause damage to the flat rollers 312 and convex rollers 322 due to contact with the high-temperature rolled steel. At this time, the cooling medium flows into the three-way housing 42 through the main inlet pipe 41, then flows into the main inlet pipes 45 of the first and second cooling components, and then flows into the flat rollers 312 and convex rollers 322 through the inlet branch pipes 46 provided on the main inlet pipes 45. It also flows into the flat rollers 312 and convex rollers 322 through the spray holes provided on the inlet branch pipes 46 to cool the flat rollers 312 and convex rollers 322. Finally, the cooling medium flows into the outlet branch pipe 48 from the outlet provided on the sealing cover 47, and is discharged through the main outlet pipe 49.

[0071] When the push cylinder 21 moves the rear mounting frame 6 to the loading station, during the movement, the L-shaped push rod 410 on the second control component on the rear mounting frame 6 will move together with the rear mounting frame 6. When the rear mounting frame 6 approaches the loading station, the roller 411 on the L-shaped push rod 410 will touch the drive rotating plate 44 and drive the left end of the drive rotating plate 44 to rotate to the right. At this time, the adjusting baffle 43 will rotate together with the drive rotating plate 44. As the adjusting baffle 43 rotates, the channel size between the input main pipe 45 of the second cooling component and the discharge port on the rear side of the three-way housing 42 will be expanded, and the channel size between the input main pipe 45 of the first cooling component and the discharge port on the front side of the three-way housing 42 will be reduced, thereby increasing the speed at which the cooling medium flows to the input main pipe 45 of the second cooling component and improving the heat exchange efficiency of the flat roller 312 and the convex roller 322 on the rear mounting frame 6 at the loading station.

[0072] Example 3: In some embodiments, such as Figure 11 As shown in a preferred embodiment of the present invention, the synchronous cleaning mechanism 5 includes a driving synchronous pulley 51, a driven synchronous pulley 52, a synchronous belt 53, a rotating shaft 54, brush bristles 55, and a fixed support frame 56. The output ends of the first motor 311 and the second motor 321 are both fixedly mounted with the driving synchronous pulley 51. The fixed support frame 56 is fixedly mounted on the mounting frame 6. The driven synchronous pulley 52 is rotatably mounted on the fixed support frame 56. The driving synchronous pulley 51 and the driven synchronous pulley 52 are connected by a synchronous belt 53 around their outer ends. One end of the rotating shaft 54 ​​is fixedly connected to the driven synchronous pulley 52, and the other end of the rotating shaft 54 ​​is rotatably connected to the mounting frame 6. A plurality of brush bristles 55 are fixedly arranged on the rotating shaft 54.

[0073] In this invention, when the first motor 311 and the second motor 321 work on the flat roller 312 and the convex roller 322 to transport the rolled steel, the first motor 311 and the second motor 321 also drive the synchronous pulley 51 to rotate. The synchronous pulley 51 drives the synchronous belt 53 to rotate, which in turn drives the driven synchronous pulley 52 to rotate. The driven synchronous pulley 52 then drives the rotating shaft 54 ​​and the brush 55 to rotate together. At this time, the brush 55 cleans the surfaces of the flat roller 312 and the convex roller 322. This prevents dust from adhering for a long time and reduces the amount of extra cleaning work required.

[0074] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
