Description

Technical Field

[0001] This invention relates to the field of billet cooling equipment, specifically to a billet cooling device for alloy processing. Background Technology

[0002] A billet is a semi-finished steel billet formed after molten steel solidifies. It is also the raw material for subsequent rolling into various steel products. Molten steel is cooled and solidified by continuous casting machine (continuous casting) or ingot casting. Currently, the mainstream is continuous casting billet. According to the shape, there are slab billets, square billets, rectangular billets, round billets, and irregular billets. It can be directly hot-rolled and processed into final products such as plates, sections, pipes, and strips. It is a key intermediate product between steelmaking and rolling, and its quality directly affects the performance of the final steel.

[0003] Continuous casting billets are a type of billet. Continuous casting billets are usually made and cooled using continuous casting machines. In the alloy processing process, the supporting equipment of the continuous casting machine includes steel pouring equipment, continuous casting machine body equipment, cutting area equipment, and conveying equipment. When processing alloy billets, the continuous casting machine generally pours high-temperature alloy steel into one or a group of water-cooled copper crystallizers. The alloy steel gradually solidifies into a billet shell along the periphery of the crystallizer. After the steel liquid level rises to a certain height and the billet shell solidifies to a certain thickness, the straightening machine pulls out the billet and cools it with water in the secondary cooling zone to make the billet completely solidify. The cutting device then cuts it into fixed lengths according to the requirements of steel rolling. The secondary cooling zone is a crucial part of the rapid cooling and forming of the continuously cast billet. It typically consists of multiple sets of rotating rollers arranged vertically in a fan-shaped section. When the billet enters the fan-shaped section, it is rapidly cooled and formed by integrated water mist sprayers on its surface. However, in the existing fan-shaped section, most of the weight of the continuously cast billet is borne by the inner rotating rollers during cooling. When the inner rotating rollers bear the overheated billet for a long time, it is easy to cause thermal deformation and seizing, resulting in a decrease in the conveying speed and errors in the straightening and straightening of the continuously cast billet.

At the same time, the water flow impacts the spiral plate, driving the first connector and fan blades to rotate and generating wind. The wind is then blown onto the alloy casting billet through the exhaust duct for further air cooling, which further improves the cooling efficiency of the alloy casting billet.

[0018] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figure 1-11 A billet cooling device for alloy processing includes an inner support plate 1, inner rollers 11 are rotatably connected to both sides of the inner support plate 1, a side frame 12 is rotatably connected to one end of the inner rollers 11 that is far apart from each other, a limit frame 121 is fixed to the surface of the side frame 12, a mounting frame 2 is fixed to the surface of the inner support plate 1, a second motor 21 is fixed inside the mounting frame 2, a rotating shaft 22 is fixed to the output shafts at both ends of the second motor 21, a limit plate 23 is threadedly connected to the surface of the rotating shaft 22, and the limit plate 23 is slidably connected to the inner rollers 11.

[0020] A cross connector 3 is fixed inside one end of the inner roller 11. A connecting rod 31 is fixed at both ends of the cross connector 3. A support ring 32 is fixed on the surface of the connecting rod 31. A water passage 33 is opened on the surface of the support ring 32. A fixing pipe 4 is fixed on one side of the side frame 12. A water tank 41 is fixed at one end of the fixing pipe 4. A first balance plate 42 is fixed on the surface of the water tank 41 near the inner support plate 1. A cylinder 43 is fixed on both sides of the first balance plate 42. A second balance plate 44 is fixed on the output shaft of the cylinder 43. An outer support plate 45 is fixed on the surface of the second balance plate 44. An outer roller 46 is rotatably connected to both ends of the outer support plate 45. A side plate 47 is rotatably connected to both ends of the outer roller 46.

[0021] The top of the inner support plate 1 is fixed with a first water pipe 101, and the side of the side frame 12 is fixed with a first motor 13. The output shaft of the first motor 13 is fixed with a connecting shaft 14. The connecting shaft 14 passes through the side frame 12 and is rotatably connected to the side frame 12. One end of the connecting shaft 14 is fixed to an inner roller 11 away from the first water pipe 101. A limit frame 121 is fixed on the surface of the side frame 12. One end of the rotating shaft 22 passes through the limit frame 121 and is rotatably connected to the limit frame 121. The top of the outer support plate 45 is fixed with a second water pipe 451. The curvature of the inner support plate 1, the water tank 41 and the outer support plate 45 are equal.

[0022] Specifically, before actual operation, the cylinder 43 is first started by the controller. The cylinder 43 pushes the second balance plate 44 and the outer support plate 45, so that the outer support plate 45 drives the outer roller 46 and the side plate 47 to adjust, thereby adjusting the distance between the outer roller 46 and the inner roller 11. After the distance adjustment is completed, the external water source injects cooling water into the inner support plate 1 and the outer support plate 45 through the first water pipe 101 and the second water pipe 451 respectively. After the water injection is completed, the water supply to the first water pipe 101 and the second water pipe 451 is stopped.

[0023] Then, the second motor 21 is started by the controller, which drives the rotating shaft 22 to rotate. The rotating shaft 22 then drives the limiting plate 23 to be adjusted along the surface of the inner roller 11, so that the distance between the limiting plate 23 and the inner support plate 1 is adjusted. Thus, the limiting plate 23 can limit the billet during the straightening process, preventing it from shifting, thereby reducing wear and improving the quality of alloy billet processing.

[0024] After the alloy billet passes through the crystallizer for the first cooling and is discharged, it falls between the inner roller 11 and the outer roller 46. During this process, the alloy billet slides under the action of gravity. In the process of sliding, it rubs against the inner roller 11 and the outer roller 46, and drives the inner roller 11 and the outer roller 46 to rotate. Then, in the process of continuous sliding, the alloy billet gradually cools down and the outer shell hardens. Subsequently, under the guidance of the inner roller 11 and the outer roller 46, it changes from vertical to arc shape, and then from arc shape to long plate shape, thus forming a slab. It is then discharged through an inner roller 11 that is away from the first water pipe 101.

[0025] Next, the first motor 13 is started by the controller, which drives the connecting shaft 14 to rotate. The connecting shaft 14 drives the inner roller 11 connected to it to rotate. Then, the inner roller 11 pulls the alloy casting billet to continue to be horizontally conveyed, waiting to enter the subsequent cutting area for cutting.

[0026] Furthermore, when the alloy billet moves between the inner roller 11 and the outer roller 46, and causes the inner roller 11 and the outer roller 46 to rotate, most of the weight of the alloy billet is borne by the inner roller 11, while the inside of the inner roller 11 is borne by the support ring 32. The support ring 32 plays the role of supporting the inner roller 11, reducing the probability of the inner roller 11 being deformed by heat.

[0027] Meanwhile, the inner layer rollers 11 on both sides of the inner layer support plate 1 are in an unsealed connection state. That is, under the action of the cross connector 3, the two inner layer rollers 11 are connected into a whole, and both inner layer rollers 11 are in an open state. At this time, the cooling water inside the inner layer support plate 1 can enter the interior of the inner layer roller 11 through the open inner layer roller 11, and the cooling water fills the inner layer roller 11. The water pressure then supports the inner layer roller 11 from the inside out again, maintaining the shape of the surface of the inner layer roller 11. Meanwhile, the heat on the surface of the alloy billet can be transferred to the inner roller 11 when it passes through the inner roller 11. At this time, the cooling water carries away the heat from the surface of the inner roller 11, thereby indirectly cooling the alloy billet and improving the cooling efficiency of the alloy billet.

[0028] It should be noted that all the devices in this invention are controlled by a controller. The inner roller 11 is connected by a cross connector 3, and the outer roller 46 is also connected by a cross connector 3. That is, the outer roller 46 is also provided with a cross connector 3, a connecting rod 31, a support ring 32 and a water passage 33. When the alloy billet moves between the inner roller 11 and the outer roller 46, it drives the inner roller 11 and the outer roller 46 to rotate. The inner roller 11 and the outer roller 46 can then simultaneously cool the surface of the alloy billet, further improving the cooling efficiency of the alloy billet.

[0029] Meanwhile, under the action of the limiting plate 23, the inner roller 11 can be further supported, which further reduces the probability of deformation of the inner roller 11.

[0030] After the alloy billet has cooled, the second motor 21 can be started by the controller. The second motor 21 drives the rotating shaft 22 to drive the limiting plate 23 to slide along the surface of the inner roller 11. During the sliding process, the limiting plate 23 can clean the surface of the inner roller 11, reducing the probability of residual iron oxide scale adhering to the surface of the inner roller 11 and reducing the probability of iron oxide scale scratching the alloy billet.

[0031] Meanwhile, during the sliding process, the limiting plate 23 can perform a correction operation on the inner roller 11, so that the inner roller 11, which has been deformed, can be restored to a circular shape, reducing the probability of the inner roller 11 seizing up, thereby improving the stability of the inner roller 11 in driving the alloy casting billet and improving the product quality after the alloy casting billet is cooled.

[0032] During the cooling process, cooling water can be injected into the inner support plate 1 and the outer support plate 45 through the first water pipe 101 and the second water pipe 451, and the cooled water after absorbing heat can be discharged to the outside through the water outlets opened at the bottom of the inner support plate 1 and the outer support plate 45. This allows water to circulate inside the inner support plate 1 and the outer support plate 45, and the cooled water discharged from the inner support plate 1 and the outer support plate 45 can be reused after cooling, thereby saving water consumption and playing a role in energy conservation and emission reduction.

[0033] Example 2: A water supply pipe 5 is fixed to the top of the water storage tank 41. A sealing plate 51 is fixed to the inside of the water supply pipe 5 near the side frame 12. An atomizing nozzle 52 is fixed to the surface of the fixed pipe 4 near the outer roller 46. A hollow wall 6 is opened inside the side frame 12. An exhaust duct 61 is opened on the inner wall of the hollow wall 6. A first connector 62 is rotatably connected to the inner wall of the hollow wall 6. One end of the first connector 62 passes through the side frame 12 and the fixed pipe 4 and is rotatably sealed to the sealing plate 51.

[0034] A fan blade 63 is fixed to the surface of the first connector 62 located inside the hollow wall 6. A spiral plate 64 is fixed to the surface of the first connector 62 located inside the fixed pipe 4. A U-shaped rod 65 is fixed to the surface of the side plate 47. One end of the U-shaped rod 65 is slidably connected to the side frame 12 and located inside the hollow wall 6. A second connector 66 is fixed to the end of the U-shaped rod 65 located inside the hollow wall 6. A baffle plate 67 is fixed to one side of the second connector 66. The baffle plate 67 abuts against the inner wall of the hollow wall 6 near the exhaust duct 61.

[0035] Specifically, based on Embodiment 1, when the alloy billet moves toward the end of the inner support plate 1 away from the first water pipe 101 under the guidance and transmission of the inner roller 11 and the outer roller 46, that is, when the alloy billet is converted to horizontal transmission and movement, the water supply pipe 5 can be connected to an external water pump, and the external water pump can continuously inject cooling water into the interior of the water storage tank 41.

[0036] After the cooling water enters the interior of the water storage tank 41, it gradually enters the interior of each fixed pipe 4 and is sprayed out through the atomizing nozzle 52, so that the cooling water is turned into water mist and sprayed onto the surface of the alloy casting billet to further cool down the alloy casting billet. While the cooling water is continuously pumped into the water storage tank 41.

[0037] As cooling water enters the interior of the fixed pipe 4 and is sprayed out through the atomizing nozzle 52, a stable water flow is formed inside the fixed pipe 4. The water flow can impact the spiral plate 64, causing the spiral plate 64 to drive the first connecting member 62 to rotate, which in turn causes the first connecting member 62 to drive the fan blade 63 to rotate inside the hollow wall 6. This generates airflow inside the hollow wall 6, which can then be blown through the exhaust duct 61 into the inner roller 11 and the outer roller 46. This allows for the continuous pumping of cooling water into the water tank 41 to provide pressure, enabling the alloy billet to be cooled by water mist while also receiving air cooling, further increasing the cooling speed of the alloy billet and improving the efficiency of the alloy billet production process.

[0038] It should be noted that a U-shaped rod 65 is fixed to the surface of the side plate 47, and one end of the U-shaped rod 65 is slidably connected to the side frame 12 and located inside the hollow wall 6. At the same time, a second connector 66 and a baffle plate 67 are fixed to this end. When the cylinder 43 is started, the cylinder 43 pushes the second balance plate 44, the outer support plate 45 and the outer roller 46 to adjust, so that the inner roller 11 and the outer roller 46 can remain in contact with the surface of the alloy casting, while the outer roller 46 can drive the side plate 47 and the U-shaped rod 65 to adjust synchronously.

[0039] Then, the U-shaped rod 65 drives the second connecting piece 66 and the baffle plate 67 to adjust synchronously. By adjusting the baffle plate 67, the range of the exhaust duct 61 to be covered is selected. This ensures that the exhaust duct 61 is covered by the baffle plate 67, reducing the opening area of ​​the exhaust duct 61. This concentrates the airflow on the inner side of the inner roller 11 and the outer roller 46. Furthermore, since the opening area of ​​the exhaust duct 61 is reduced, the wind speed can be increased, thereby improving the effect of air cooling.

[0040] Example 3: A spray head 7 is fixed on the surface of the water tank 41 near the outer support plate 45. An extension rod 8 is fixed on the surface of the limiting plate 23 near the fixed pipe 4 at both ends. An arc frame 81 is fixed on one end of the extension rod 8. A guide groove 82 is opened on the surface of the arc frame 81 near the atomizing nozzle 52. Water baffles 83 are fixed on both sides of the top of the guide groove 82.

[0041] Specifically, based on Embodiment 1 and Embodiment 2, when the second motor 21 is started, it drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the limiting plate 23 to slide and adjust along the surface of the inner rotating roller 11. During the movement of the limiting plate 23, the limiting plate 23 drives the extension rod 8 and the arc frame 81 to move synchronously. By moving the baffle plate 83, the atomizing nozzles 52 that cannot directly spray onto the casting billet are blocked, causing the cooling water sprayed by the atomizing nozzles 52 at the edge to be injected into the interior of the guide groove 82. Under the guidance of the guide groove 82, the direction of the water mist sprayed by the atomizing nozzles 52 at the edge is changed, so that the water mist is sprayed toward the side of the alloy casting billet. This avoids the situation of the atomizing nozzles 52 at the edge spraying dry. In addition, in conjunction with the spray head 7, the spray head 7 and the atomizing nozzles 52 on both sides of the alloy casting billet spray water mist onto the alloy casting billet, thereby making more comprehensive use of each atomizing nozzle 52, improving the utilization rate of the atomizing nozzles 52, and concentrating the effect of water cooling.

[0042] It should be noted that baffle plates 83 are fixed on both sides of the top of the guide channel 82. By setting the baffle plates 83, the splashing caused by the atomizing nozzle 52 impacting the guide channel 82 can be reduced, the waste of cooling water can be reduced, and the cooling water can enter the interior of the guide channel 82 more concentratedly. Under the water impact and guidance of the guide channel 82, it is sprayed out to the side of the alloy casting billet.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
