Description

Technical Field

[0001] This invention relates to the field of crystallizer technology, and more specifically to a cooling roller device for an ultra-thin strip spraying machine. Background Technology

[0002] In the single-roll rapid quenching technology, molten material is sprayed onto a rotating cooling roll, which rapidly cools the molten material. The rotation of the cooling roll also stretches the molten material, eventually forming an ultra-thin strip that is then peeled off from the cooling roll.

[0003] The cooling effect of the cooling roller directly affects the forming quality of the strip. Existing cooling rollers generally use two cooling methods: one is that the coolant flows from one end to the other, and the other is that it flows from the middle to both ends. These two methods either cause a significant temperature difference between the two sides or between the middle and the two sides. As a result, the temperature of the two sides and the middle of the strip is inconsistent at the same horizontal position during cooling, which can easily lead to deformation and increased internal stress. Therefore, a cooling roller device with uniform cooling is needed. Summary of the Invention

[0004] To overcome the aforementioned technical problems, the present invention aims to provide a cooling roller device for an ultra-thin strip spraying machine. Through the setting of the flow-pushing module, when the rotating shaft drives the copper sleeve to rotate, the second rubbing roller rotates, thereby causing the positioning rod to drive the fixing component to move in a circle. The fixing component drives the moving plate to move. When the moving plate moves in the direction of liquid flow, it pushes the liquid flow, thereby causing the liquid on both sides of the second arc-shaped cavity and the liquid in the middle position to move as a whole, reducing or eliminating the flow velocity difference between the liquid flow in the middle and on both sides of the second arc-shaped cavity, thereby reducing or eliminating the temperature difference between the two sides and the middle part of the second arc-shaped cavity, reducing the temperature difference of the copper sleeve in the transverse direction, and improving the strip forming quality.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A cooling roller device for an ultra-thin strip spraying machine includes a copper sleeve. One end of the copper sleeve is fixedly connected to a sealing plate, and one end of the sealing plate is fixedly connected to a rotating shaft. The copper sleeve includes an inner annular wall located on its inner side. One end of the inner annular wall is rotatably connected to an annular plate. A ring member is fixedly connected to one side of the annular plate, and one end of the ring member is rotatably sleeved with the sealing plate. Partition plates are fixedly connected to the bottom and top ends of the outer wall of the ring member. An arc-shaped cavity is formed between the copper sleeve and the ring member on one side of the two partition plates, and an arc-shaped cavity is formed between the copper sleeve and the ring member on the other side of the two partition plates. A liquid injection module is fixedly connected to the bottom side of the inner wall of the ring member, and a liquid outlet module is fixedly connected to the top side of the inner wall of the ring member. A connecting member is fixedly connected to the outer wall of the annular plate, and an inlet pipe and an outlet pipe are fixedly connected to the inner wall of the connecting member. One end of the inlet pipe... The liquid injection module is connected to the liquid outlet module, and the liquid injection module is connected to one end of arc cavity one and one end of arc cavity two. The liquid outlet module is connected to the other end of arc cavity one and the other end of arc cavity two. Multiple flow-pushing modules are equidistantly fixed to the outer wall of the ring on the other side of the two partition plates. The rotating shaft drives the copper sleeve to rotate, while the ring remains stationary. The part of the copper sleeve in contact with the strip is cooled through arc cavity two. The liquid in arc cavity two moves clockwise, and the molten material moves counterclockwise on the copper sleeve. When the temperature at the bottom of arc cavity two is low, the coolant cools the low-temperature part of the strip through the copper sleeve. When the temperature at the top of arc cavity two is high, the coolant cools the high-temperature part of the strip through the copper sleeve. This makes the gradient of the coolant and the strip adaptable, thus effectively cooling the strip.

[0007] Furthermore, the propulsion module includes two fixed plates. The top of each fixed plate is fixedly connected to the outer wall of the ring. A second roller is rotatably connected to the bottom of one side wall of each fixed plate, and a first roller is rotatably connected to the top of one side wall of each fixed plate. A positioning rod is rotatably connected between the outer edge of the side wall of the first roller and the outer edge of the adjacent side wall of the second roller. A connecting rod is fixedly connected to the top of the positioning rod, and a fixing member is fixedly connected to one end of the connecting rod. A lever is rotatably connected to the middle position of the two fixing members. When the rotating shaft drives the copper sleeve to rotate, the second roller rotates. Roller 2 drives roller 1 to rotate synchronously through the positioning rod, so that the positioning rod maintains its own angle and revolves. The movement of the positioning rod causes the fixing part to move in a circle, and the fixing part causes the dial plate to move. When the dial plate moves in the direction of liquid flow, the dial plate pushes the liquid flow, so that the liquid on both sides of the arc cavity 2 and the liquid in the middle position move as a whole, reducing or eliminating the flow velocity difference between the liquid flow in the middle and the liquid flow on both sides of the arc cavity 2, thereby reducing or eliminating the temperature difference between the two sides and the middle part of the arc cavity 2, reducing the temperature difference of the copper sleeve in the lateral direction, and improving the strip forming quality.

[0008] Furthermore, a second stop bar is fixedly connected between one end of the two fixed members, and a first stop bar is fixedly connected between the other ends of the two fixed members. The first stop bar is used to restrict the inward deflection of the lever, and the second stop bar is used to restrict the outward deflection of the lever, thereby limiting the angle between the lever and the fixed plate to an acute angle, which facilitates the deflection of the lever when it moves in a circle.

[0009] Furthermore, the extension line of the fixed plate along its length passes through the central axis of the ring, enabling multiple levers to push the liquid flow.

[0010] Furthermore, the injection module includes a sealing element, with cavities on both sides of the sealing element. A wheel shaft is rotatably connected between the inner walls of both ends of the cavities. An impeller is fixedly sleeved on the outer wall of the wheel shaft. A placement cavity is provided at one end of each of the two cavities of the sealing element. One end of the wheel shaft penetrates an inner wall of the cavity, and a gear is fixedly connected to one end of the wheel shaft. The two gears mesh with each other. A connecting pipe is provided above the sealing element. A connecting pipe is fixedly connected to the outer wall of the connecting pipe and the outer walls of both sides of the sealing element. The bottom end of the connecting pipe is connected to the adjacent cavity, and the top end of the connecting pipe is connected to the connecting pipe. One end of the connecting pipe is connected to one end of the inlet pipe. A second connecting pipe is fixedly connected to the bottom of the sealing element corresponding to the lower part of the two cavities. The second connecting pipe is fixedly connected to the cavities with an annular joint, and one second connecting pipe is connected to the first arc-shaped cavity, while the other second connecting pipe is connected to the arc-shaped cavity. The two chambers are connected. The liquid outlet module and the liquid injection module have the same structure. The connecting pipe in the liquid outlet module is connected to one end of the liquid outlet pipe. The coolant enters the connecting pipe through the liquid inlet pipe. The liquid in the connecting pipe enters the two chambers through the two connecting pipes and drives the impeller to rotate. Through the setting of two meshing gears, the two impellers rotate synchronously in opposite directions, so that the liquid flow rate entering the two chambers is similar. The liquid in one chamber enters the arc-shaped chamber one through the connecting pipe two, and the liquid in the other chamber enters the arc-shaped chamber two through the corresponding connecting pipe two. The liquid moves from the bottom end to the top end of the arc-shaped chamber two and is discharged through the liquid outlet module and the liquid outlet pipe. Similarly, the liquid in the arc-shaped chamber one enters from the bottom end and is discharged from the top end, avoiding the difference in coolant flow rate caused by the difference in resistance in the arc-shaped chamber one and arc-shaped chamber two, so that there is a sufficient amount of coolant entering both the arc-shaped chamber one and arc-shaped chamber two.

[0011] Furthermore, the outer wall of the copper sleeve has a groove, which facilitates the restriction of the molten material to form a strip.

[0012] Furthermore, a middle plate is fixedly connected between the other end of the inlet pipe and the other end of the outlet pipe, and the middle plate is fixedly connected to the inner side wall of one end of the connector, thereby fixing the inlet pipe and the outlet pipe to the connector.

[0013] Furthermore, multiple guide plates are equidistantly fixed to one side of the inner wall of the arc-shaped cavity, and the adjacent two guide plates are staggered, so that the coolant moves from the bottom of the arc-shaped cavity to the top of the arc-shaped cavity along a serpentine trajectory, thereby reducing the temperature difference between the two sides of the copper sleeve located in part of the arc-shaped cavity and facilitating the cooling of the copper sleeve.

[0014] The beneficial effects of this invention are:

[0015] 1. By setting up the flow-pushing module, when the rotating shaft drives the copper sleeve to rotate, the second roller rotates. The second roller drives the first roller to rotate synchronously through the positioning rod, so that the positioning rod maintains its own angle and revolves. The movement of the positioning rod drives the fixed part to move in a circle. The fixed part drives the dial plate to move. When the dial plate moves in the direction of liquid flow, the dial plate pushes the liquid flow, so that the liquid on both sides of the arc cavity two and the liquid in the middle position move as a whole, reducing or eliminating the flow velocity difference between the liquid flow in the middle of the arc cavity two and the liquid flow on both sides, thereby reducing or eliminating the temperature difference between the two sides and the middle part of the arc cavity two, reducing the temperature difference of the copper sleeve in the lateral direction, and improving the strip forming quality.

[0016] 2. By setting up arc-shaped cavity one and arc-shaped cavity two, the rotating shaft drives the copper sleeve to rotate while the ring remains stationary. The part of the copper sleeve in contact with the strip is cooled through arc-shaped cavity two. The liquid in arc-shaped cavity two moves clockwise, while the molten material moves counterclockwise on the copper sleeve. When the temperature at the bottom of arc-shaped cavity two is lower, the coolant cools the low-temperature part of the strip through the copper sleeve. When the temperature at the top of arc-shaped cavity two is higher, the coolant cools the high-temperature part of the strip through the copper sleeve. This makes the gradient between the coolant and the strip adaptable, thus effectively cooling the strip. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-10As shown, a cooling roller device for an ultra-thin strip spraying machine includes a copper sleeve 100, one end of which is fixedly connected to a sealing plate 200, and the other end of the sealing plate 200 is fixedly connected to a rotating shaft 210. The copper sleeve 100 includes an inner ring wall 120 located on the inner side, one end of which is rotatably connected to a ring plate 300. A ring member 301 is fixedly connected to one side of the ring plate 300, one end of which is rotatably sleeved with the sealing plate 200. A partition plate 310 is fixedly connected to both the bottom and top ends of the outer wall of the ring member 301. An arc-shaped cavity 330 is formed between the sleeve 100 and the ring 301 on one side of the two partition plates 310, and an arc-shaped cavity 340 is formed between the sleeve 100 and the ring 301 on the other side of the two partition plates 310. A liquid injection module 350 is fixedly connected to the bottom side of the inner wall of the ring 301, and a liquid outlet module 390 is fixedly connected to the top side of the inner wall of the ring 301. A connector 320 is fixedly connected to the outer wall of the ring plate 300, and an inlet pipe 370 and an outlet pipe 380 are fixedly connected to the inner wall of the connector 320. One end of pipe 370 is connected to injection module 350, and outlet pipe 380 is connected to outlet module 390. Injection module 350 is connected to one end of arc cavity one 330 and one end of arc cavity two 340. Outlet module 390 is connected to the other end of arc cavity one 330 and the other end of arc cavity two 340. Multiple flow-pushing modules 360 are equidistantly fixed to the outer wall of ring 301 on the other side of the two partition plates 310. Rotating shaft 210 drives copper sleeve 100 to rotate, while ring 301 remains stationary. The portion of the copper sleeve 100 in contact with the strip is cooled through the arc-shaped cavity 340. The liquid in the arc-shaped cavity 340 moves clockwise, while the molten material moves counterclockwise on the copper sleeve 100. When the temperature at the bottom of the arc-shaped cavity 340 is lower, the coolant cools the low-temperature portion of the strip through the copper sleeve 100. When the temperature at the top of the arc-shaped cavity 340 is higher, the coolant cools the high-temperature portion of the strip through the copper sleeve 100. This allows the coolant and the strip to be adapted to each other's gradients, thus effectively cooling the strip.

[0031] The propulsion module 360 ​​includes two fixed plates 361. The top of the fixed plate 361 is fixedly connected to the outer wall of the ring 301. A second roller 363 is rotatably connected to the bottom of one side wall of the fixed plate 361, and a first roller 362 is rotatably connected to the top of one side wall of the fixed plate 361. A positioning rod 364 is rotatably connected between the outer edge of one side wall of roller 362 and the outer edge of the adjacent second side wall of roller 363. A connecting rod 365 is fixedly connected to the top of the positioning rod 364. A fixing member 366 is fixedly connected to the end. A lever plate 369 is rotatably connected at the middle position of the two fixing members 366. When the rotating shaft 210 drives the copper sleeve 100 to rotate, the second roller 363 rotates. The second roller 363 drives the first roller 362 to rotate synchronously through the positioning rod 364, so that the positioning rod 364 maintains its own angle and revolves. The movement of the positioning rod 364 causes the fixing member 366 to move in a circle. The fixing member 366 drives the lever plate 369 to move. When the lever plate 369 moves... When moving in the direction of liquid flow, the lever 369 pushes the liquid flow, thereby causing the liquid on both sides of the arc cavity 340 and the liquid in the middle position to move as a whole, reducing or eliminating the velocity difference between the liquid flow in the middle and the liquid flow on both sides of the arc cavity 340, thereby reducing or eliminating the temperature difference between the two sides and the middle part of the arc cavity 340, reducing the temperature difference of the copper sleeve 100 in the transverse direction, and improving the strip forming quality. A stop bar 368 is fixed between one end of the two fixing parts 366, and a stop bar 367 is fixed between the other ends of the two fixing parts 366. The stop bar 367 is used to limit the inward deflection of the lever 369, and the stop bar 368 is used to limit the outward deflection of the lever 369, thereby limiting the angle between the lever 369 and the fixing plate 361 to an acute angle, so as to facilitate the deflection of the lever 369 when it moves in a circle. The extension line of the length direction of the fixing plate 361 passes through the center axis of the ring 301, so that multiple levers 369 can push the liquid flow.

[0032] The injection module 350 includes a seal 351, with cavities 359 on both sides of the seal 351. A wheel axle 356 is rotatably connected between the inner walls of both ends of the cavity 359. An impeller 355 is fixedly sleeved on the outer wall of the wheel axle 356. A mounting cavity 357 is provided at one end of each of the two cavities 359 of the seal 351. One end of the wheel axle 356 penetrates an inner wall of the cavity 359 and is fixedly connected to a gear 358. The two gears 358 mesh with each other. A connecting pipe 352 is provided above the seal 351. A connecting pipe 353 is fixedly connected to both outer walls of the outer side of the seal 351. The bottom end of the connecting pipe 353 is connected to the adjacent cavity 359, and the top end of the connecting pipe 353 is connected to the connecting pipe 352. One end of the connecting pipe 352 is connected to one end of the inlet pipe 370. A connecting pipe 354 is fixedly connected to the bottom of the seal 351 below the two cavities 359. The connecting pipe 354 is fixedly connected to the ring 301, and one connecting pipe 354 is connected to the arc-shaped cavity 330, and the other connecting pipe 354 is connected to the arc-shaped cavity 340. The liquid module 390 has the same structure as the liquid injection module 350. The connecting pipe 352 in the liquid outlet module 390 is connected to one end of the liquid outlet pipe 380. Coolant enters the connecting pipe 352 through the inlet pipe 370. The liquid in the connecting pipe 352 enters two chambers 359 through two connecting pipes 353, driving the impeller 355 to rotate. Through the arrangement of two meshing gears 358, the two impellers 355 rotate synchronously in opposite directions, thus making the liquid flow rates entering the two chambers 359 approximately equal. The liquid in one chamber 359 flows through the connecting pipe... Liquid enters the first arc-shaped cavity 330 through pipe 354. Liquid in another cavity 359 enters the second arc-shaped cavity 340 through the corresponding connecting pipe 354. Liquid moves from the bottom to the top of the second arc-shaped cavity 340 and is discharged through the liquid outlet module 390 and the liquid outlet pipe 380. Similarly, liquid in the first arc-shaped cavity 330 enters from the bottom and exits from the top, avoiding the difference in coolant flow rate caused by the difference in resistance in the first arc-shaped cavity 330 and the second arc-shaped cavity 340, so that there is a sufficient amount of coolant entering both the first arc-shaped cavity 330 and the second arc-shaped cavity 340.

[0033] The outer wall of the copper sleeve 100 has a groove 110 to facilitate the confinement of the molten material to form a strip. A middle plate 321 is fixedly connected between the other end of the inlet pipe 370 and the other end of the outlet pipe 380. The middle plate 321 is fixedly connected to the inner wall of one end of the connector 320, fixing the inlet pipe 370 and the outlet pipe 380 to the connector 320. Multiple guide plates 331 are fixedly connected at equal intervals on one side of the inner wall of the arc cavity 330, and the two adjacent guide plates 331 are staggered, so that the coolant moves from the bottom end of the arc cavity 330 along a serpentine trajectory to the top end of the arc cavity 330, thereby reducing the temperature difference between the two sides of the copper sleeve 100 in the arc cavity 330 part and facilitating the cooling of the copper sleeve 100.

[0034] Working Principle: In use, connect the rotating shaft 210 to the external drive device, fix the connector 320 to the external mounting base, and connect the other end of the inlet pipe 370 to the external coolant supply pipe. The coolant enters the connecting pipe 352 through the inlet pipe 370. The liquid in the connecting pipe 352 enters the two chambers 359 through two connecting pipes 353, driving the impeller 355 to rotate. Through the setting of two meshing gears 358, the two impellers 355 rotate synchronously in opposite directions, thereby making the liquid flow rate entering the two chambers 359 approximately the same. The liquid in one chamber 359 enters the arc-shaped cavity 330 through the connecting pipe 354, and the liquid in the other chamber 359 enters the arc-shaped cavity 340 through the corresponding connecting pipe 354. The liquid moves from the bottom to the top of the arc-shaped cavity 340 and is discharged through the outlet module 390 and outlet pipe 380. Similarly, the liquid in the arc-shaped cavity 330 enters from the bottom and exits from the top.

[0035] During cooling, the rotating shaft 210 drives the copper sleeve 100 to rotate counterclockwise. Molten material sprays down from the top of the groove 110, spreads downwards along the groove 110, and gradually cools and detaches. As the rotating shaft 210 drives the copper sleeve 100 to rotate, the second roller 363 rotates. The second roller 363 drives the first roller 362 to rotate synchronously through the positioning rod 364, thus allowing the positioning rod 364 to maintain its own angle and revolve. The movement of the positioning rod 364 causes the fixing part 366 to move in a circle, and the fixing part 366 drives the lever plate. When the lever 369 moves in the direction of liquid flow, it deflects outward under resistance and is restricted by the stop lever 368, thereby promoting the overall flow of liquid. This facilitates the flow of liquid on both sides of the arc-shaped cavity 340, reducing or eliminating the velocity difference between the liquid flow in the middle and on both sides of the arc-shaped cavity 340. This reduces or eliminates the temperature difference between the sides and the middle of the arc-shaped cavity 340, and reduces the temperature difference of the copper sleeve 100 in the transverse direction, thus uniformly cooling the strip and reducing the temperature difference in the strip. The uneven cooling between the two sides leads to a decrease in quality. When the deflector 369 moves against the liquid flow direction, it deflects inward under resistance, reducing the force-bearing area. Simultaneously, the liquid in the arc-shaped cavity 340 moves clockwise, while the molten material moves counterclockwise on the copper sleeve 100. When the temperature is lower at the bottom of the arc-shaped cavity 340, the coolant cools the low-temperature portion of the strip through the copper sleeve 100. When the temperature is higher at the top of the arc-shaped cavity 340, the coolant cools the high-temperature portion of the strip through the copper sleeve 100. Cooling is achieved by adapting the coolant to the gradient of the strip, thus effectively cooling the strip. The arc-shaped cavity 330 provides auxiliary cooling to the portion of the copper sleeve 100 that is not in contact with the strip, thereby reducing the temperature of the copper sleeve 100. Through the arrangement of multiple guide plates 331, the coolant moves from the bottom of the arc-shaped cavity 330 along a serpentine trajectory to the top of the arc-shaped cavity 330, thereby reducing the temperature difference between the two sides of the copper sleeve 100 located in the arc-shaped cavity 330 and facilitating the cooling of the copper sleeve 100.
