Description

Technical Field

[0001] This utility model relates to the field of metallurgical equipment technology, and more specifically, to a cooling water seal structure for a continuous casting machine. Background Technology

[0002] During continuous casting, the billet temperature can typically reach over 1400℃. The rollers of the continuous casting machine come into direct contact with these high-temperature billets, therefore effective cooling measures are essential to protect the rollers from overheating deformation and damage. Traditional cooling methods involve rapidly circulating cooling water through a water-sealed system to ensure stable roller operating temperatures. This stable temperature control not only helps reduce roller deformation and damage caused by overheating but also promotes uniform cooling of the billet, thereby reducing the risk of internal cracks and surface defects and improving the quality of the final product.

[0003] However, existing cooling systems typically use a bellows-type mechanical seal structure as a compensation mechanism to cool the continuous casting machine rolls. The fixed end of this water seal system is installed on the roll's water baffle, while the rotating end is fixed inside the roll and connected to a water tank via a rigid pipe to achieve the circulation of cooling water. However, in practical applications, this design has been found to have serious leakage problems, resulting in high water consumption, unsatisfactory cooling effect on the continuous casting rolls, and a significantly shortened service life. More seriously, once leakage occurs, the lack of an online replacement mechanism means the water seal cannot be replaced in a timely manner, severely affecting the normal operating efficiency and stability of the continuous casting production line. Utility Model Content

[0004] This invention provides a cooling water seal structure for a continuous casting machine, which can improve the reliability of the water seal system, reduce resource waste, extend equipment service life, and ensure the continuity and efficiency of the production process.

[0005] The embodiments of this utility model can be implemented as follows:

[0006] In a first aspect, this utility model provides a cooling water seal structure for a continuous casting machine, comprising:

[0007] Inner tube;

[0008] A rotating roller, which is movably sleeved outside the inner tube;

[0012] An elastic element, one end of which abuts against the fixed seat and the other end of which abuts against the second sealing element, so that the first sealing element and the second sealing element abut against each other.

[0013] In an optional embodiment, the first seal and / or the second seal are made of tungsten carbide.

[0014] In an optional embodiment, the inner tube includes an outer shaft and an inner shaft, the outer shaft being sleeved on the inner shaft, and the first seal being disposed on the inner shaft.

[0015] In an optional embodiment, the continuous casting machine cooling water seal structure further includes a support member and a friction-reducing pad. The support member is disposed between the rotating roller and the outer shaft and is used to follow the movement of the rotating roller. The friction-reducing pad is disposed at the end of the support member and located between the inner tube and the outer shaft.

[0016] In an optional embodiment, the continuous casting machine cooling water seal structure further includes a water baffle cover, which is detachably mounted on the mounting base and is located at one end outside the outer shaft and outside the rotating roller.

[0017] In an optional embodiment, the continuous casting machine cooling water seal structure further includes a third sealing element disposed between the rotating roller and the water baffle.

[0018] In an optional embodiment, the continuous casting machine cooling water seal structure further includes a connector, which is disposed at one end of the inner shaft and the outer shaft. The connector is provided with a first water inlet channel and a first water outlet channel. The inner shaft is provided with a second water inlet channel, and a second water outlet channel is provided between the outer shaft and the inner shaft. The first water inlet channel is connected to the second water inlet channel, and the first water outlet channel is connected to the second water outlet channel.

[0019] In an optional embodiment, the continuous casting machine cooling water seal structure further includes an anti-rotation component. The connector is connected to the inner pipe and is used to input or output cooling water to the inner pipe. One end of the anti-rotation component is fixedly engaged with the water baffle cover, and the other end is fixedly engaged with the connector.

[0020] In an optional embodiment, the continuous casting machine cooling water seal structure further includes two water supply hoses, which are respectively connected to the first water inlet channel and the first water outlet channel.

[0021] In an optional embodiment, the continuous casting machine cooling water seal structure further includes an elastic column, through which the second sealing element and the fixed seat are sequentially passed, and the elastic element is sleeved on the elastic column.

[0022] The beneficial effects of the continuous casting machine cooling water seal structure provided in this embodiment include: a fixed seat is provided on the rotating roller to rotate synchronously with it, so that the second sealing element provided on the fixed seat rotates synchronously with it; a first sealing element is provided in the inner tube. Therefore, when the rotating roller rotates relative to the inner tube, the first and second sealing elements move relative to each other, and dynamic sealing is achieved by the first and second sealing elements abutting against each other. Furthermore, by providing an elastic element to provide a pre-tightening force towards the first sealing element to compensate for the axial displacement of the first or second sealing element caused by wear, it is ensured that the first and second sealing elements can always maintain a tight abutting state even after wear, forming a sealing friction pair, thereby effectively achieving a sealing function. It is evident that the continuous casting machine cooling water seal structure effectively improves sealing reliability, completely solves the leakage problem, reduces resource waste, and extends equipment service life, thereby ensuring the continuity and efficiency of the equipment in the production process.

[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0035] During continuous casting, the billet temperature can typically reach over 1400℃. The rollers of the continuous casting machine come into direct contact with these high-temperature billets, therefore effective cooling measures are essential to protect the rollers from overheating deformation and damage. Traditional cooling methods involve rapidly circulating cooling water through a water-sealed system to ensure stable roller operating temperatures. This stable temperature control not only helps reduce roller deformation and damage caused by overheating but also promotes uniform cooling of the billet, thereby reducing the risk of internal cracks and surface defects and improving the quality of the final product.

[0036] However, existing cooling systems typically use a bellows-type mechanical seal structure as a compensation mechanism to cool the continuous casting machine rolls. The fixed end of this water seal system is installed on the roll's water baffle, while the rotating end is fixed inside the roll and connected to a water tank via a rigid pipe to achieve the circulation of cooling water. However, in practical applications, this design has been found to have serious leakage problems, resulting in high water consumption, unsatisfactory cooling effect on the continuous casting rolls, and a significantly shortened service life. More seriously, once leakage occurs, the lack of an online replacement mechanism means the water seal cannot be replaced in a timely manner, severely affecting the normal operating efficiency and stability of the continuous casting production line.

[0037] Based on the problems existing in the current technology, please refer to Figures 1 to 4 This utility model provides a cooling water seal structure 10 for a continuous casting machine to improve the reliability of the water seal system, reduce resource waste, extend equipment service life, and ensure the continuity and efficiency of the production process.

[0038] In detail, the continuous casting machine cooling water seal structure 10 includes an inner tube 100, a rotating roller 200, a first seal 300, a second seal 400, a fixed seat 500, and an elastic element 600.

[0039] The rotating roller 200 is movably sleeved outside the inner tube 100. The first sealing element 300 is disposed in the inner tube 100 and is used to rotate synchronously with the rotating roller 200. The second sealing element 400 is disposed in the fixed seat 500 and abuts against the first sealing element 300. The fixed seat 500 is disposed in the rotating roller 200 so that the second sealing element 400 and the fixed seat 500 rotate synchronously with the rotating roller 200. One end of the elastic element 600 abuts against the fixed seat 500 and the other end abuts against the second sealing element 400. The elastic element 600 is used to provide an elastic force to the second sealing element 400 to move toward the first sealing element 300.

[0040] In this embodiment, a fixed seat 500 is provided on the rotating roller 200 to rotate synchronously with it, so that the second sealing member 400 provided on the fixed seat 500 rotates synchronously with it. A first sealing member 300 is provided on the inner tube 100. Therefore, when the rotating roller 200 rotates relative to the inner tube 100, the first sealing member 300 and the second sealing member 400 move relative to each other. By making the first sealing member 300 and the second sealing member 400 abut against each other, dynamic sealing is achieved.

[0041] Since the first seal 300 and the second seal 400 will wear against each other while moving relative to each other, an elastic element 600 is provided to provide a pre-tightening force to the second seal 400 toward the first seal 300. This compensates for the axial displacement of the first seal 300 or the second seal 400 caused by wear, ensuring that the first seal 300 and the second seal 400 can always maintain a tight fit even after wear, so as to form a sealing friction pair and thus effectively play a sealing role.

[0042] As can be seen, the continuous casting machine cooling water seal structure 10 provided by this utility model embodiment effectively improves the sealing reliability, completely solves the water leakage problem, reduces resource waste, and extends the service life of the equipment, thereby ensuring the continuity and efficiency of the equipment in the production process.

[0043] It should be noted that at least one of the first seal 300 and the second seal 400 is made of tungsten carbide.

[0044] It is worth noting that tungsten carbide is an extremely hard material, second only to diamond in hardness. Using tungsten carbide as a dynamic sealing material can greatly improve the wear resistance of the seal, reduce wear caused by high-speed rotation, and thus extend the service life of the seal.

[0045] Furthermore, tungsten carbide exhibits excellent resistance to most chemicals, including acids, alkalis, and other corrosive media. This means that seals made from this material can maintain stable performance in harsh working environments and are not easily affected by corrosion.

[0046] Furthermore, tungsten carbide maintains its physical and mechanical properties at extremely high temperatures, making it an ideal choice for applications in high-temperature environments. Especially in continuous casting processes facing extremely high temperatures, dual tungsten carbide seals can effectively prevent deformation or damage caused by excessively high temperatures.

[0047] Furthermore, tungsten carbide has a smooth surface and a low coefficient of friction, which helps reduce frictional losses between the seal and the mating surface, reducing energy consumption and heat accumulation caused by friction, thus further protecting the integrity of the sealing system. Tungsten carbide also has high strength properties; double tungsten carbide seals can withstand high operating pressures without deformation, ensuring reliable sealing performance under high-pressure conditions.

[0048] In summary, the application of tungsten carbide dual-material in dynamic seals not only provides excellent wear resistance, corrosion resistance, and high-temperature resistance, but also ensures a low coefficient of friction and excellent compressive strength, making it particularly suitable for industrial applications with extremely stringent sealing requirements, such as heavy plate continuous casting machines. These characteristics work together to significantly improve the safety and reliability of equipment operation, while also reducing maintenance costs and downtime.

[0049] Furthermore, the inner tube 100 includes an outer shaft 110 and an inner shaft 120, with the outer shaft 110 sleeved on the inner shaft 120, and the first seal 300 disposed on the inner shaft 120 and located at the end of the outer shaft 110.

[0050] It is worth mentioning that the outer shaft 110 and the inner shaft 120 are relatively fixed and neither of them rotates with the rotating roller 200.

[0051] Furthermore, the continuous casting machine cooling water seal structure 10 also includes a support member 700, which is disposed between the rotating roller 200 and the outer shaft 110 and is used to follow the movement of the rotating roller 200.

[0052] In this embodiment, the support member 700 is an oilless bearing made of a material with self-lubricating properties. Therefore, by setting the support member 700 at the rotating roller 200, the support member 700 can move relative to the outer shaft 110 and slide against it while rotating with the rotating roller 200. This can ensure that the support member 700 rotates stably relative to the outer shaft 110 and also achieve a sealing effect to a certain extent.

[0053] Furthermore, the continuous casting machine cooling water seal structure 10 also includes a friction-reducing pad 1500, which is disposed at the end of the support member 700 and located between the outer shaft 110 of the inner tube 100.

[0054] In this embodiment, the friction-reducing pad 1500 is made of polytetrafluoroethylene material, which can effectively reduce the rotational friction resistance between the outer shaft 110 and the support 700.

[0055] Furthermore, the continuous casting machine cooling water seal structure 10 also includes a water baffle 800, which is detachably mounted on the mounting base by bolts and located at one end outside the rotating roller 200.

[0056] In this embodiment, by installing the water-blocking cover 800 at the end of the rotating roller 200, the water-blocking cover 800 can also protect the rotating roller 200 and other components from water stains or dust and other impurities, thereby extending the service life and reducing the frequency and cost of maintenance; and the water-blocking cover 800 helps to keep the working environment of the rotating roller 200 dry and clean, and can effectively play a protective role.

[0057] Furthermore, the continuous casting machine cooling water seal structure 10 also includes a third seal 900, which is disposed between the rotating roller 200 and the water baffle 800.

[0058] In this embodiment, a third sealing element 900 is provided between the rotating roller 200 and the water-blocking cover 800 to enhance the sealing performance and further improve the protective effect.

[0059] Optionally, the third seal 900 may be, but is not limited to, a skeleton oil seal.

[0060] Furthermore, the continuous casting machine cooling water seal structure 10 also includes an anti-rotation component 1000 and a connector 1100. The connector 1100 is connected to the inner pipe 100 and is used to input or output cooling water to the inner pipe 100. One end of the anti-rotation component 1000 is fixedly engaged with the water baffle 800, and the other end is fixedly engaged with the connector 1100.

[0061] In this embodiment, one end of the anti-rotation member 1000 is fixedly connected to the water baffle 800 and the other end to the connector 1100 to prevent the connector 1100 from rotating, thereby improving the structural stability of the continuous casting machine cooling water seal structure 10.

[0062] It is understandable that the anti-rotation component 1000 can be, but is not limited to, a screw.

[0063] Furthermore, the connector 1100 is located at one end of the inner shaft 120 and the outer shaft 110, and the connector 1100 is fixed to the outer shaft 110 by bolts, thereby ensuring structural stability and preventing the connector 1100 from falling off the outer shaft 110.

[0064] The connector 1100 is provided with a first water inlet channel 1110 and a first water outlet channel 1120. The inner shaft 120 is provided with a second water inlet channel 130. A second water outlet channel 140 is provided between the outer shaft 110 and the inner shaft 120. The first water inlet channel 1110 is connected to the second water inlet channel 130, and the first water outlet channel 1120 is connected to the second water outlet channel 140.

[0065] It is understandable that the water-blocking cover 800 is located at the end of the rotating roller 200 near the connector 1100.

[0066] In this embodiment, cooling water flows sequentially through the first inlet channel 1110, the second inlet channel 130, the second outlet channel 140, and the first outlet channel 1120. During this process, cooling water is also input into the equipment through the second inlet channel 130. After the cooling water undergoes heat exchange, it flows back from the equipment to the second outlet channel 140.

[0067] It is worth mentioning that the first seal 300 and the second seal 400 are located at the second water outlet channel 140. Therefore, through the sealing effect of the first seal 300 and the second seal 400, water leakage can be effectively avoided during the operation of the continuous casting machine cooling water seal structure 10, thus avoiding resource waste.

[0068] Furthermore, the continuous casting machine cooling water seal structure 10 also includes two water supply hoses 1200, which are respectively connected to the first water inlet channel 1110 and the first water outlet channel 1120.

[0069] It is understood that the two water supply hoses 1200 are connected to the water tank, so cooling water can be input into the first water inlet channel 1110 of the connector 1100 through the supply hoses, and the heat-exchanged cooling water can be output through the water supply hoses 1200 connected to the first water outlet channel 1120.

[0070] Furthermore, the continuous casting machine cooling water seal structure 10 also includes an elastic column 1300, through which a second sealing element 400 and a fixing seat 500 are sequentially inserted, and an elastic element 600 is sleeved on the elastic column 1300.

[0071] In this embodiment, the elastic post 1300 is an elastic pin. Therefore, the second seal 400 can be securely installed on the fixed seat 500 through the elastic post 1300, thereby improving its structural stability and realizing that the second seal 400 and the fixed seat 500 move synchronously with the rotating roller 200.

[0072] The elastic element 600 is sleeved on the elastic column 1300, which can also ensure that the direction of the elastic restoring force generated by the elastic element 600 remains consistent, so that the elastic element 600 always applies a stable elastic force to the second seal 400.

[0073] Furthermore, since the elastic column 1300 also has the ability to deform elastically, when the first seal 300 and the second seal 400 wear against each other and cause axial displacement, the elastic column 1300 can extend adaptively to avoid gaps between the first seal 300 and the second seal 400, thus ensuring that the first seal 300 and the second seal 400 can always play an effective sealing role.

[0074] Furthermore, the continuous casting machine cooling water seal structure 10 also includes a sealing assembly 1400, which includes a first sealing ring 1410, a second sealing ring 1420, a third sealing ring 1430, a fourth sealing ring 1440, and a fifth sealing ring 1450.

[0075] Specifically, the first sealing ring 1410 is disposed between the joint 1100 and the outer shaft 110, the second sealing ring 1420 is disposed between the rotating roller 200 and the outer shaft 110, the third sealing ring 1430 is disposed between the second sealing element 400 and the fixed seat 500, the fourth sealing element is disposed between the fixed seat 500 and the rotating roller 200, and the fifth sealing ring 1450 is disposed on the outer wall of the rotating roller 200, thereby further improving the sealing performance between the various components in the continuous casting machine cooling water seal structure 10.

[0076] Furthermore, the continuous casting machine cooling water seal structure 10 also includes an elastic washer 1600, which is disposed between the fixed seat 500 and the rotating roller 200 to improve the stability of the fixed seat 500 and the rotating roller 200 and ensure that the fixed seat 500 and the rotating roller 200 remain relatively fixed.

[0077] In summary, this utility model embodiment provides a cooling water seal structure 10 for a continuous casting machine. A fixed seat 500 is provided on the rotating roller 200 to rotate synchronously with it, so that the second sealing member 400 provided on the fixed seat 500 rotates synchronously with it. A first sealing member 300 is provided in the inner tube 100. Therefore, when the rotating roller 200 rotates relative to the inner tube 100, the first sealing member 300 and the second sealing member 400 move relative to each other, thereby achieving dynamic sealing by making the first sealing member 300 and the second sealing member 400 abut against each other. By setting the elastic element 600 to provide a pre-tightening force to the second seal 400 toward the first seal 300, the axial displacement of the first seal 300 or the second seal 400 caused by wear is compensated, ensuring that the first seal 300 and the second seal 400 can still effectively perform the sealing function even after wear. It can be seen that the continuous casting machine cooling water seal structure 10 effectively improves the sealing reliability, completely solves the water leakage problem, reduces resource waste, and extends the service life of the equipment, thereby ensuring the continuity and efficiency of the equipment in the production process.
