Abstract
Description
Technical Field
[0001] This utility model relates to the field of continuous casting equipment technology, specifically to a spraying device for the fan-shaped section of a continuous casting round billet. Background Technology
[0002] During continuous casting of round billets, nozzles on the spray ring continuously spray atomized water onto the billet surface, thereby rapidly cooling the billet surface. (Reference) Figure 1 Because the fan-shaped section itself has an arc, some of the atomized water sprayed by the nozzle located on the inner arc side of the fan-shaped section will condense into water droplets and roll down along the roller until it drips onto the inner arc surface of the billet at the end of the fan-shaped section, causing surface quality problems of the continuously cast billet and resulting in the billet bending.
[0003] In existing technologies, when the amount of water dripping from the inner arc side of the fan-shaped section is too large, maintenance personnel need to use sheet metal to divert the water at the end of the fan-shaped section. However, due to the high ambient temperature, this could cause burns and pose a significant safety hazard. Therefore, there is an urgent need to design a water diversion device that can be easily and quickly installed and solves the on-site problem. Utility Model Content
[0004] The purpose of this invention is to provide a spraying device for the fan-shaped section of a continuously cast round billet, so as to solve the problem that the water sprayed by the spraying ring will drip onto the inner arc surface of the billet.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A spraying device for the fan-shaped section of a continuously cast round billet includes:
[0007] A spraying assembly, comprising multiple spraying rings, which are spaced apart along the billet discharge direction in a fan-shaped section of the continuous casting machine, with spray nozzles evenly distributed on each spraying ring;
[0008] A water-guiding assembly includes a water-guiding trough and a quick-release connector. The water-guiding trough is detachably installed at the bottom of the spray ring at the end of the fan-shaped segment via the quick-release connector and is located on the inner arc side of the fan-shaped segment. The water-guiding trough includes a first water-guiding section and a second water-guiding section connected to each other. The first water-guiding section has a first opening extending to the outer arc side of the fan-shaped segment, and the second water-guiding section has a second opening extending to the outer arc side of the fan-shaped segment. The distance between the first water-guiding section and the spray ring gradually increases from one end near the second water-guiding section to the first opening, and the distance between the second water-guiding section and the spray ring gradually increases from one end near the first water-guiding section to the second opening, so that both the first and second water-guiding sections have a slope, thereby guiding the water dripping from the inner arc side of the fan-shaped segment to the outer arc side of the fan-shaped segment, preventing residual water from splashing onto the surface of the cast billet, and improving the surface quality of the cast billet.
[0009] Furthermore, the first water intake section includes a first base plate and two first side plates, which are disposed opposite each other on both sides of the first base plate. The first ends of the first base plate and the two first side plates are connected to the second water intake section, and a first opening is formed between the second ends of the first base plate and the two first side plates. The distance between the first end of the first base plate and the spray ring gradually increases from the second end to the first end. The first base plate has a slope to ensure that the water flow naturally converges and is guided along the first base plate to the outer arc side; by setting the first side plates, the impact and splashing of the water flow can be effectively reduced.
[0010] Furthermore, the second water intake section includes a second base plate and two second side plates, which are disposed opposite each other on both sides of the second base plate. The first ends of the second base plate and the two second side plates are connected to the first water intake section, and a second opening is formed between the second ends of the second base plate and the two second side plates. The distance between the first end of the second base plate and the spray ring gradually increases from the second end to the second end. The second base plate has a slope to ensure that the water flow naturally converges and flows along the second base plate to the outer arc side; by setting the second side plates, the impact and splashing of the water flow can be effectively reduced.
[0011] Furthermore, the quick-release connector includes a spring clip or a magnetic connector. Spring clips or magnetic connectors are common connectors that enable quick assembly and disassembly of the water inlet tank.
[0012] Furthermore, it also includes an adjustable hook, which is located in the middle of the water inlet channel and is used to adjust the distance between the water inlet channel and the spray ring to adapt to different billet diameters.
[0013] Furthermore, the height adjustment range of the adjustable hook is 200–500 mm.
[0014] Furthermore, the height of the first side plate and the second side plate is 15-30mm.
[0015] Furthermore, the width of the first base plate and the second base plate is 140-160 mm.
[0016] Furthermore, the angle between the first water intake section and the spray ring is 5° to 10°, and the angle between the second water intake section and the spray ring is 5° to 10°.
[0017] Furthermore, when the spray ring is a regular octagon, the top view of the water inlet channel is a semi-octagon. Since the water inlet channel only needs to be installed on the inner arc side, the shape of the water inlet channel is preferably half of the overall shape of the spray ring.
[0018] This invention has the following advantages over the prior art:
[0019] 1. This utility model discloses a spraying device for a fan-shaped section of a continuously cast round billet, comprising a spraying assembly and a water guiding assembly. The spraying assembly includes multiple spray rings spaced apart along the billet discharge direction in the fan-shaped section of the continuous casting machine. The water guiding assembly includes a water guiding trough and quick-release connectors. The water guiding trough is installed on the spray ring at the end of the fan-shaped section via the quick-release connectors, located on the inner arc side of the fan-shaped section. This water guiding trough collects the cooling water dripping from the spray ring above and guides it to the outer arc side of the fan-shaped section, preventing residual water from splashing onto the billet surface and improving the surface quality of the billet. By designing this device, there is no need for manual hand-held iron sheet to guide the water, reducing safety hazards. Moreover, the water guiding trough is installed on the spray ring via quick-release connectors, enabling rapid assembly and disassembly. The structure is simple and the manufacturing cost is low. It can be installed on spray rings of different specifications.
[0020] 2. The water inlet channel in this utility model has an overall tilt angle of 5° to 10° to ensure natural water convergence. It features a U-shaped cross-section, with a first side plate positioned opposite each other in the first water inlet section and a second side plate positioned opposite each other in the second water inlet section, effectively reducing water impact and splashing. Quick-release connectors use common spring clips or magnetic components, allowing for rapid installation / removal without tools, and are compatible with the fan-shaped segment structures of different manufacturers. An adjustable hook (adjustment range 200–500 mm) allows adjustment of the distance between the water inlet channel and the spray ring to accommodate different billet diameters. The overall weight is <5 kg, reducing operational burden. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, they should not be construed as limitations on this utility model.
[0032] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale.
[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be further discussed and described in the description of the subsequent figures.
[0034] Example:
[0035] refer to Figure 1The sector section 1 of the continuous casting machine is curved, thus it can be divided into an inner arc side and an outer arc side. The cooling water droplets condensed by the nozzles 4 located on the outer arc side will not drip onto the billet 2; moreover, the cooling water sprayed by the upper spray ring nozzles will not fall directly, but will flow layer by layer along the rollers to drip at the end of the sector section. Therefore, the water guide trough 5 in this device is installed on the spray ring 3 at the end of the sector section, located on the inner arc side of sector section 1, to collect the cooling water dripping from the inner arc side of the upper spray ring. The water guide trough 5 itself has a slope that can guide the collected cooling water to the outer arc side area of the sector section, keeping it away from the billet and reducing its impact on the surface quality of the billet.
[0036] The following is a detailed introduction to this device: (e.g.) Figures 1 to 8 As shown, this utility model provides a spraying device for a fan-shaped section of a continuously cast round billet, comprising: a spraying assembly and a water guiding assembly; the spraying assembly includes multiple spraying rings 3, which are spaced apart along the billet discharge direction in the fan-shaped section 1 of the continuous casting machine, and each spraying ring 3 has a uniformly distributed nozzle 4; the water guiding assembly includes a water guiding channel 5 and a quick-release connector 6; the water guiding channel 5 is detachably installed at the bottom of the spraying ring 3 at the end of the fan-shaped section 1 via the quick-release connector 6, and is located on the inner arc side of the fan-shaped section 1, and the water guiding channel 5 includes a first water guiding section 501 connected to it. The first water-guiding section 501 has a first opening 5011 extending to the outer arc side of the fan-shaped section 1, and the second water-guiding section 502 has a second opening 5021 extending to the outer arc side of the fan-shaped section 1. The distance between the first water-guiding section 501 and the spray ring 3 gradually increases from one end near the second water-guiding section 502 to the first opening 5011, and the distance between the second water-guiding section 502 and the spray ring 3 gradually increases from one end near the first water-guiding section 501 to the second opening 5021, so that both the first and second water-guiding sections have a slope. The water-guiding trough 5 is installed at the bottom of the inner arc side of the spray ring at the end of the fan-shaped section, which can collect the cooling water flowing down from the inner arc side of the upper spray ring and converge it to the outer arc side, preventing residual water from splashing onto the surface of the billet and improving the surface quality of the billet. With the above settings, there is no need for manual handling of sheet metal to guide the water, reducing safety hazards, and the quick-release connectors can also achieve quick disassembly and assembly, facilitating daily cleaning and replacement.
[0037] Specifically, the angle between the first water inlet section 501 and the spray ring 3 is 5° to 10°, and the angle between the second water inlet section 502 and the spray ring 3 is 5° to 10°. The slope between the first water inlet section 501 and the second water inlet section 502 should not be too large to avoid affecting the billet discharge.
[0038] Specifically, the first water intake section 501 includes a first base plate 5012 and two first side plates 5013. The two first side plates 5013 are disposed opposite each other on both sides of the first base plate 5012. The first ends of the first base plate 5012 and the two first side plates 5013 are connected to the second water intake section 501. A first opening 5011 is formed between the second ends of the first base plate 5012 and the two first side plates 5013. The distance between the first end and the second end of the first base plate 5012 and the spray ring gradually increases. Through the above arrangement, the first base plate 5012 has a slope, ensuring that the water flow naturally converges and is guided along the first base plate 5012 to the outer arc side. The first side plates 5013 on both sides of the first base plate 5012 can effectively reduce water impact and splashing.
[0039] The structure of the second water intake section 502 is the same as that of the first water intake section 501. The second water intake section 502 includes a second base plate 5022 and two second side plates 5023. The two second side plates 5023 are arranged opposite each other on both sides of the second base plate 5022. The first ends of the second base plate 5022 and the two second side plates 5023 are connected to the first water intake section 501. A second opening 5021 is formed between the second ends of the second base plate 5022 and the two second side plates 5023. The distance between the second base plate 5022 and the spray ring 3 gradually increases from the first end to the second end. This arrangement gives the second base plate 5022 a slope, ensuring that the water flow naturally converges and flows along the second base plate 5022 to the outer arc side. The second side plates 5023 on both sides of the second base plate 5022 can effectively reduce water impact and splashing. The height of the first side plate 5013 and the second side plate 5023 is 15-30mm. The width of the first base plate 5012 and the second base plate 5022 is 140-160mm, which can collect the cooling water flowing down from above without affecting the casting billet.
[0040] In this embodiment, the quick-release connector 6 uses either a spring clip or a magnetic connector, both of which are common connectors and readily available on the market. Mounting holes 503 are provided on the water inlet trough 5 for installing the quick-release connector 6. The water inlet trough 5 is installed onto the spray ring of the fan-shaped section using the quick-release connector 6, allowing for tool-free installation / removal; furthermore, it is compatible with spray rings from different manufacturers.
[0041] This embodiment also includes an adjustable hook 7, which is located in the middle of the water inlet trough 5 and is used to adjust the distance between the water inlet trough 5 and the spray ring 3 to accommodate different billet diameters. The adjustable hook can be purchased commercially, and specifically, the height adjustment range of the adjustable hook is 200-500mm, such as 200mm, 250mm, 300mm, 400mm, 500mm, etc.
[0042] Since the water inlet trough 5 only needs to be installed on the inner arc side, its shape is preferably half the overall shape of the spray ring. For example, in this embodiment, when the spray ring 3 is a regular octagon, the water inlet trough is designed as a half-octagon. In other embodiments, the shape of the water inlet trough 5 is adjusted according to the shape of the spray ring 3.
[0043] For specific usage: refer to... Figure 7 and Figure 8 The water inlet trough is installed at the bottom of the spray ring at the end of the fan-shaped section using a quick-release connector, located on the inner arc side. The distance between the water inlet trough and the spray ring is then adjusted using adjustable hooks to ensure it does not interfere with the billet ejection process. The water inlet trough collects cooling water dripping from the inner arc side of the upper fan-shaped section and directs it to the outer arc side, keeping the cooling water away from the billet and reducing its impact on the surface quality of the billet.
[0044] Compared with manual removal using sheet metal, this device can reduce residual water splashing by more than 90%, significantly reducing surface defects of the cast billet. It also has the following advantages: efficient maintenance, with disassembly and assembly time of less than 1 minute using quick-release connectors, facilitating daily cleaning and replacement; low cost, using all standardized parts, reducing manufacturing costs by more than 40%; and high adaptability, compatible with continuous casting machines for round billets from Φ150 to Φ600mm.
[0045] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
