[0002] The continuous casting machine roll is one of the core components of continuous casting equipment. Its design and operating status directly affect the stability of continuous casting production, the quality of the cast billet, and the lifespan of the equipment. In actual production, the continuous casting machine roll operates in a high-temperature environment, with cooling water continuously evaporating from the roll surface. Salts such as calcium and magnesium, as well as impurities contained in the cooling water, precipitate and adhere to the metal surface upon heating, forming scale and oxides. These scale and oxides not only reduce the cooling effect of the roll but also cause the roll surface temperature to rise, affecting the functional accuracy of the online sector section, thereby reducing the roll's lifespan and increasing equipment maintenance costs and downtime.

[0039] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0040] The following is for reference. Figures 1-4 This application describes a continuous casting machine sector section roller surface cleaning device according to an embodiment of the present application.

[0041] Please see Figures 1-4 This application provides a continuous casting machine sector section roller surface cleaning device 1, which includes: a bracket 11, an adjustment component 12, a pipeline component 13, and multiple nozzles 14.

[0042] The bracket 11 is used for installation on the continuous casting machine; the adjustment assembly 12 is movably installed on the bracket 11; the pipeline assembly 13 includes a main pipe 131 and multiple secondary pipes 132. The main pipe 131 is connected to a high-pressure water pipe and installed on the adjustment assembly 12. The multiple secondary pipes 132 are respectively connected to the main pipe 131; multiple nozzles 14 are correspondingly installed on the multiple secondary pipes 132. The nozzle 14 has a slit structure, and the length direction of the slit is parallel to the axial direction of the roller.

[0043] The bracket 11 provides the mounting base for the entire cleaning device, stably fixing it to the continuous casting machine. The bracket 11 can be made of metal, such as a frame structure welded from steel plates, or a support structure formed by splicing structural steel sections. Its specific shape can be adapted to the installation location of the continuous casting machine to ensure stable installation. There are several ways to connect the bracket 11 to the continuous casting machine. For example, it can be connected by bolts, with multiple bolt holes pre-drilled on the bracket 11 corresponding to the mounting holes on the continuous casting machine, and the two fixed together with bolts. Alternatively, a snap-fit ​​structure can be used, with slots on the continuous casting machine and corresponding locking blocks on the bracket 11, achieving installation through the cooperation of the locking blocks and slots.

[0044] The adjustment component 12 is movably mounted on the bracket 11 and can adjust the positions of the pipeline component 13 and the nozzle 14 to adapt to the cleaning needs of the roller surface under different working conditions and ensure the cleaning effect. The adjustment component 12 can have various structural embodiments. For example, it can be a sliding block and slide rail structure, with the slide rail mounted on the bracket 11, the sliding block slidably mounted on the slide rail, and the pipeline component 13 mounted on the sliding block. Position adjustment is achieved by the sliding of the sliding block on the slide rail. Alternatively, it can be a telescopic structure, such as one composed of multiple nested sleeves, where the length is changed by the extension and retraction of the sleeves, thereby adjusting the position of the pipeline component 13. The movable connection between the adjustment component 12 and the bracket 11 can be a sliding connection, a rotating connection, or a connection that can both slide and rotate, depending on the actual adjustment requirements.

[0045] The piping assembly 13 includes a main pipe 131 and multiple secondary pipes 132. The main pipe 131 introduces high-pressure water from the high-pressure water pipe and distributes it to each secondary pipe 132. The secondary pipes 132 then deliver the high-pressure water to their corresponding nozzles 14. The main pipe 131 is connected to the high-pressure water pipe, which can be a flange connection, where the two are fixed together by flanges and bolts to ensure a tight seal; or a threaded connection, where matching threads are provided at the ends of the main pipe 131 and the high-pressure water pipe, and the connection is tightened by screwing. The main pipe 131 is installed on the adjusting assembly 12, and its connection method can be welding or detachably fixed to the adjusting assembly 12 using clamps or other connecting parts, to facilitate the maintenance and replacement of the main pipe 131.

[0046] Multiple auxiliary pipes 132 are connected to the main pipe 131, either by welding or through connectors such as tee fittings, allowing the high-pressure water in the main pipe 131 to be distributed to the various auxiliary pipes 132. It is understood that the main pipe 131 extends along the arrangement direction of the multiple rollers of the continuous casting machine, and the multiple auxiliary pipes 132 are located on the same side of the main pipe 131 to correspond to the multiple rollers. The number of auxiliary pipes 132 is not specifically limited and is designed according to the number of rollers.

[0047] Multiple nozzles 14 are correspondingly mounted on multiple secondary pipes 132 to spray high-pressure water in a specific shape to clean the roller surface. The connection between the nozzles 14 and the secondary pipes 132 can be a threaded connection, with matching threads at the ends of the nozzles 14 and secondary pipes 132 for easy installation and replacement; or it can be a plug-in connection sealed with a sealing ring. The nozzles 14 have a slit structure, with the length of the slit parallel to the roller's axial direction. This design increases the cleaning area of ​​a single nozzle 14, allowing the sprayed high-pressure water to form a long, narrow water flow along the roller's axial direction, covering more of the roller surface and improving cleaning efficiency. The width of the slit can be designed according to the required water pressure and cleaning intensity to ensure water flow strength and spray accuracy. The number of nozzles 14 corresponds to the number of secondary pipes 132, and their positions correspond to the secondary pipes 132, ensuring that each nozzle 14 can accurately receive high-pressure water from the secondary pipe 132.

[0048] In actual operation, the bracket 11 is installed on the continuous casting machine. The position of the pipeline assembly 13 is adjusted by the adjustment component 12 so that multiple nozzles 14 correspond to multiple rollers in the fan-shaped section of the continuous casting machine, and the slit length direction of the nozzle 14 is parallel to the axial direction of the roller. When the roller needs to be cleaned, the water valve on the high-pressure water pipe is opened to deliver high-pressure water to the main pipe 131. The main pipe 131 distributes the high-pressure water to each secondary pipe 132, and the secondary pipes 132 then deliver the high-pressure water to the corresponding nozzle 14. The nozzle 14 sprays high-pressure water onto the roller surface through the nozzle of the slit structure. The impact force of the high-pressure water flow removes scale, oxides and other impurities from the roller surface, achieving online cleaning of the roller surface.

[0049] According to the embodiments of this application, the continuous casting machine sector section roller surface cleaning device 1 achieves stable installation of the entire device on the continuous casting machine through the bracket 11; the adjustment component 12 can flexibly adjust the position of the pipeline component 13 and the nozzle 14 to ensure that the nozzle 14 is precisely aligned with the roller surface, thus guaranteeing the cleaning effect; the main pipe 131 and multiple auxiliary pipes 132 of the pipeline component 13 cooperate to achieve effective distribution of high-pressure water, which can simultaneously provide high-pressure water to multiple nozzles 14 to meet the synchronous cleaning needs of multiple rollers; the slit structure design of the nozzle 14 increases the cleaning area of ​​a single nozzle 14, improving cleaning efficiency. This device enables online cleaning of the sector section roller surface, avoiding problems such as reduced cooling effect, increased roller surface temperature, and shortened equipment life caused by roller surface contamination, thereby improving the service life of the rollers and reducing equipment maintenance costs and downtime.

[0050] According to some embodiments of this application, the adjustment assembly 12 may include: a fixed seat, an adjusting slide, and a first adjusting bolt. The fixed seat is detachably connected to the bracket 11; the adjusting slide is slidably engaged with the fixed seat, and the adjusting slide is provided with a clamping structure for clamping the main pipe 131; the first adjusting bolt passes through the fixed seat and abuts against the adjusting slide, and rotating the first adjusting bolt drives the adjusting slide to slide radially along the roller.

[0051] The fixed base is detachably connected to the bracket 11, providing a connection base for the entire adjustment assembly 12 and stably mounting the adjustment assembly 12 onto the bracket 11. The fixed base can be made of metal, such as cast iron or machined steel. There are several ways to detachably connect it to the bracket 11, such as by bolting, where multiple corresponding bolt holes are pre-set on both the fixed base and the bracket 11, and bolts are used to fasten them together. This connection method facilitates the installation, disassembly, and replacement of the adjustment assembly 12. Alternatively, a dovetail groove snap-fit ​​structure can be used, with a dovetail guide rail on the bracket 11 and a matching dovetail groove on the fixed base. The assembly is then secured by sliding snap-fit ​​and a positioning pin, providing better stability and positioning accuracy.

[0052] The adjusting slide is engaged with the fixed base, allowing it to slide in a specific direction under the support of the fixed base, thereby adjusting the position of the pipeline assembly 13 and nozzle 14 mounted thereon. The structural design of the adjusting slide should be compatible with the fixed base. For example, when the fixed base adopts a dovetail groove structure, the adjusting slide should be equipped with a corresponding dovetail guide rail to achieve sliding engagement. The adjusting slide is provided with a clamping structure for clamping the main pipe 131. This clamping structure can be a clamp composed of two semicircular rings. The inner wall of the semicircular rings can be provided with anti-slip materials such as rubber pads to increase the friction with the main pipe 131 and ensure that the main pipe 131 is firmly fixed on the adjusting slide. The two semicircular rings are connected by bolts. When the bolts are tightened, the semicircular rings clamp the main pipe 131; when the bolts are loosened, the position of the main pipe 131 in the clamping structure can be adjusted or the main pipe 131 can be removed.

[0053] The first adjusting bolt passes through the fixed seat and abuts against the adjusting slide. By rotating the first adjusting bolt, the rotational motion is converted into linear motion, thereby driving the adjusting slide to slide radially along the roller. The first adjusting bolt can be a high-strength metal bolt, such as carbon steel or stainless steel. A threaded hole matching the first adjusting bolt is provided on the fixed seat. After the first adjusting bolt passes through the threaded hole, its end abuts against the adjusting slide. When the first adjusting bolt is rotated clockwise, the bolt advances towards the adjusting slide, pushing the adjusting slide to slide radially outward along the roller; when the first adjusting bolt is rotated counterclockwise, the bolt retracts from the adjusting slide, and the adjusting slide slides radially inward along the roller under the action of gravity or other external forces. In this way, the sliding distance of the adjusting slide can be precisely controlled, thereby achieving precise adjustment of the distance between the nozzle 14 and the roller surface.

[0054] In actual operation, the fixed seat is first installed on the bracket 11 via a detachable connection. Then, the adjusting slide is slidably engaged with the fixed seat, and the main pipe 131 is fixed to the adjusting slide via a clamping structure. When it is necessary to adjust the distance between the nozzle 14 and the roller surface, the first adjusting bolt is rotated. The first adjusting bolt rotates in the threaded hole of the fixed seat and generates axial displacement, thereby pushing the adjusting slide to slide radially along the roller. The adjusting slide drives the main pipe 131 and the nozzle 14 to move together until the distance between the nozzle 14 and the roller surface reaches the optimal cleaning position, thus adapting to rollers of various sizes.

[0055] According to some embodiments of this application, an arc-shaped liner may be provided inside the clamping structure. The curvature of the arc-shaped liner is adapted to the outer circumferential surface of the main pipe 131, and the surface of the arc-shaped liner is provided with anti-slip texture.

[0056] An arc-shaped liner is installed within the clamping structure, its curvature matching the outer circumference of the main pipe 131. This increases the contact area between the clamping structure and the main pipe 131, allowing the clamping force to be evenly distributed across the surface of the main pipe 131, preventing excessive localized stress that could damage the main pipe 131. The arc-shaped liner can be made of metallic or non-metallic materials, such as aluminum alloy, copper alloy, or high-strength plastics. Structurally, the inner diameter of the arc-shaped liner should be approximately the same as the outer diameter of the main pipe 131 to ensure a tight fit between them.

[0057] The surface of the curved liner is provided with anti-slip texture to increase the friction between the liner and the main pipe 131, preventing the main pipe 131 from sliding within the clamping structure, thereby ensuring the stability of the main pipe 131 installation. The anti-slip texture can take various forms, such as straight lines, mesh patterns, or diamond patterns.

[0058] In some examples, the connection between the curved liner and the clamping structure can be detachable, for example, by bolts or clips securing it to the inner wall of the clamping structure. The advantage of this design is that when the curved liner becomes worn or damaged, it can be easily replaced without replacing the entire clamping structure, thus reducing maintenance costs.

[0059] According to some embodiments of this application, the adjustment assembly 12 may further include: an angle adjustment seat and a second adjustment bolt. The angle adjustment seat is hinged to the adjustment slide via a rotating shaft, and the angle adjustment seat is provided with a limiting slot for fixing the secondary tube 132. The second adjustment bolt passes through the adjustment slide and abuts against the angle adjustment seat. Rotating the second adjustment bolt drives the angle adjustment seat to rotate around the rotating shaft.

[0060] The angle adjusting seat is hinged to the adjusting slide via a rotating shaft, forming a rotating pair structure that allows the angle adjusting seat to rotate relative to the adjusting slide around the rotating shaft. This allows the angle of the secondary tube 132 and the nozzle 14 to be adjusted to suit different diameter rollers or different cleaning requirements, achieving the optimal spray angle. The angle adjusting seat can be made of metal casting or machining, and is typically block-shaped or plate-shaped, possessing a certain degree of strength and rigidity. A limiting groove is provided on the angle adjusting seat to fix the secondary tube 132. The shape of the groove is adapted to the outer circumference of the secondary tube 132, generally a semi-circular groove. The inner wall of the groove can be lined with flexible materials such as rubber pads to increase friction with the secondary tube 132 and protect the surface of the secondary tube 132 from scratches. The number of limiting grooves is the same as the number of secondary tubes 132, and they are spaced apart along the length of the angle adjusting seat.

[0061] The angle adjusting seat and the adjusting slide are hinged together by a rotating shaft. The rotating shaft is usually a cylindrical metal shaft, with both ends fixed to the adjusting slide by bearings or bushings. The angle adjusting seat is fitted onto the rotating shaft through the central shaft hole, forming a rotating pair. This connection method allows the angle adjusting seat to rotate freely around the rotating shaft within a certain range, while ensuring the smoothness of the rotation process.

[0062] The second adjusting bolt passes through the adjusting slide and abuts against the angle adjusting seat. By rotating the second adjusting bolt, the angle adjusting seat is driven to rotate around the axis, thereby achieving precise adjustment of the angles of the secondary pipe 132 and the nozzle 14. The structure of the second adjusting bolt is similar to that of the first adjusting bolt. It is made of high-strength metal and mates with the threaded hole on the adjusting slide. When the second adjusting bolt is rotated, the end of the bolt applies a pushing or pulling force to the angle adjusting seat, causing the angle adjusting seat to rotate around the axis.

[0063] In some examples, to ensure the stability and accuracy of angle adjustment, the end of the second adjusting bolt may be provided with a spherical or conical contact surface that mates with the corresponding concave surface on the angle adjusting seat, thereby reducing contact stress and preventing shaking during adjustment.

[0064] In actual operation, when it is necessary to adjust the spray angle of nozzle 14, the clamping structure can be loosened first to avoid damage to the connection between the main pipe 131 and the secondary pipe 132 caused by forcibly adjusting the angle while the main pipe 131 is fixed. Then, the second adjusting bolt can be rotated. For example, if the second adjusting bolt is rotated clockwise, the bolt end pushes the angle adjusting seat to rotate in one direction around the axis of rotation, causing the secondary pipe 132 and nozzle 14 to rotate synchronously, increasing the angle between nozzle 14 and the roller surface. If the second adjusting bolt is rotated counterclockwise, the bolt end pulls the angle adjusting seat to rotate in the opposite direction around the axis of rotation, decreasing the angle between nozzle 14 and the roller surface. After adjustment, the clamping structure can be tightened to fix the pipeline assembly 13. By precisely controlling the rotation angle of the second adjusting bolt, the nozzle 14 can be adjusted to the optimal spray angle, allowing the high-pressure water flow to impact the roller surface in the most effective way, enhancing the ability to remove stubborn dirt and improving cleaning efficiency and effect.

[0065] Meanwhile, this adjustable structural design increases the versatility and flexibility of the cleaning device, reducing the need to replace the device due to changes in roller specifications, thus lowering equipment costs and maintenance workload. Furthermore, the precise adjustment method of the second adjusting bolt ensures the accuracy and stability of angle adjustment, guaranteeing that the cleaning device is always in optimal working condition.

[0066] According to some embodiments of this application, the adjustment assembly 12 may further include: a drive motor, a displacement sensor, and a controller. The drive motor is dynamically coupled to the first adjusting bolt and / or the second adjusting bolt; the displacement sensor is used to detect the radial displacement of the adjusting slide and / or the rotation angle of the angle adjusting seat; the controller is electrically connected to the drive motor and the displacement sensor respectively, and the controller is configured to control the drive motor to drive the first adjusting bolt and / or the second adjusting bolt to rotate according to preset parameters.

[0067] The drive motor is dynamically coupled to the first and / or second adjusting bolts to provide power for the rotation of the adjusting bolts, achieving automated adjustment. The drive motor can be a stepper motor or a servo motor, featuring high precision, fast response, and controllability. The dynamic coupling connection can be implemented in various ways, such as through gear transmission, where a driving gear is mounted on the output shaft of the drive motor and a driven gear is mounted on the end of the adjusting bolt, transmitting the motor's rotational motion to the adjusting bolt through gear meshing; alternatively, it can be directly connected via belt drive or coupling to achieve synchronous rotation between the motor and the adjusting bolt. The number of drive motors can be set according to actual needs. If only the first or second adjusting bolt needs automated adjustment, only one drive motor is required; if both adjusting bolts need simultaneous adjustment, two drive motors can be used, connected to the first and second adjusting bolts respectively.

[0068] Displacement sensors are used to detect the radial displacement of the adjusting slide and / or the rotation angle of the angle adjusting seat, providing feedback data for automated adjustment. The type of displacement sensor can be selected according to the object being measured. For example, when detecting the radial displacement of the adjusting slide, linear displacement sensors, such as magnetostrictive displacement sensors or optical encoders, can be used; when detecting the rotation angle of the angle adjusting seat, angle sensors, such as photoelectric encoders or Hall effect angle sensors, can be used. The displacement sensor should be installed close to the object being measured to ensure accuracy. For example, a linear displacement sensor can be installed on a fixed base or adjusting slide, with its detection head connected to the moving parts of the adjusting slide to detect the displacement of the adjusting slide in real time; an angle sensor can be installed on a rotating shaft, rotating synchronously with the angle adjusting seat to detect the rotation angle of the angle adjusting seat.

[0069] The controller is electrically connected to both the drive motor and the displacement sensor. Its function is to control the drive motor to rotate the adjusting bolt according to preset parameters and to receive data feedback from the displacement sensor, forming a closed-loop control system for precise adjustment. The controller can be a programmable logic controller (PLC) or a microcontroller, possessing data processing, logic control, and communication functions. The controller internally stores preset parameters, including the target radial displacement of the adjusting slide and the target rotation angle of the angle adjusting seat. The controller sends control signals to the drive motor according to the preset parameters, and the drive motor drives the adjusting bolt to rotate accordingly. Simultaneously, the displacement sensor detects the radial displacement of the adjusting slide and / or the rotation angle of the angle adjusting seat in real time and feeds the detection data back to the controller. The controller compares the feedback data with the preset parameters and adjusts the control signals accordingly until the radial displacement of the adjusting slide and the rotation angle of the angle adjusting seat meet the preset parameter requirements.

[0070] In actual operation, when the position or angle of nozzle 14 needs to be adjusted, the operator inputs preset parameters into the controller via a human-machine interface or other input devices. The controller sends a control signal to the drive motor based on the preset parameters. The drive motor starts and rotates the first and / or second adjusting bolts, thereby moving the adjusting slide and / or the angle adjusting seat. Displacement sensors detect the radial displacement of the adjusting slide and / or the rotation angle of the angle adjusting seat in real time and feed the detection data back to the controller. The controller processes and analyzes the feedback data, compares it with the preset parameters, and if there is a deviation, adjusts the control signal, continuing to drive the drive motor until the radial displacement of the adjusting slide and the rotation angle of the angle adjusting seat match the preset parameters. At this point, the controller stops sending control signals to the drive motor, the drive motor stops rotating, and the adjustment of the position or angle of nozzle 14 is complete. Compared to manual adjustment, automated adjustment can more accurately adjust nozzle 14 to the optimal position and angle, ensuring the stability and consistency of the cleaning effect. At the same time, automated adjustment reduces manual intervention, lowers the labor intensity of operators, and improves production efficiency. In addition, the application of a closed-loop control system makes the adjustment process more precise and reliable, enabling timely detection and correction of deviations during the adjustment process, and ensuring that the cleaning device is always in optimal working condition.

[0071] According to some embodiments of this application, the pipeline system may further include a gas-liquid mixer connected in series with the water inlet of the main pipe 131. The gas-liquid mixer is provided with a water inlet, an air inlet and a mixed fluid outlet. The water inlet is connected to a high-pressure water pipe, the air inlet is connected to a compressed air pipe, and the mixed fluid outlet is connected to the water inlet of the main pipe 131.

[0072] Gas-liquid mixers can thoroughly mix high-pressure water and compressed air to form a two-phase flow, enhancing the cleaning effect on the roller surface. Gas-liquid mixers can employ different structural forms, such as Venturi mixers, static mixers, or jet mixers. For example, a Venturi mixer utilizes the negative pressure generated by the high-speed jet of fluid in the contraction section to draw in compressed air and mix it with high-pressure water; a static mixer, on the other hand, uses internal mixing elements to repeatedly divide and merge the fluid, achieving thorough gas-liquid mixing. Gas-liquid mixers are typically made of corrosion-resistant metal materials, such as stainless steel, to withstand high-pressure and corrosive media environments.

[0073] The water inlet connects to the high-pressure water pipe to introduce high-pressure water. The connection can be either a flange or a threaded connection to ensure a reliable seal. The air inlet connects to the compressed air pipe to introduce compressed air, also using a sealed connection. The mixed fluid outlet connects to the water inlet of the main pipe 131, delivering the mixed gas-liquid two-phase fluid to the main pipe 131. In some examples, to control the gas-liquid mixing ratio, flow regulating valves can be installed at both the air inlet and water inlet, controlling the flow rates of compressed air and high-pressure water by adjusting the valve opening.

[0074] In actual operation, high-pressure water enters the mixer through the inlet, forming a high-speed liquid flow inside. Simultaneously, compressed air is drawn into the mixer through the air inlet, where it mixes thoroughly with the high-pressure water, creating a two-phase flow containing numerous microbubbles. These microbubbles, under high pressure, are sprayed onto the roller surface with the water flow. When the bubbles contact and burst on the roller surface, they generate localized high-pressure impacts, which help to break down and remove scale, oxides, and other impurities from the roller surface, thereby improving the cleaning effect.

[0075] According to some embodiments of this application, a baffle plate can be provided inside the gas-liquid mixer. The baffle plate is fixed in a ring shape to the inner wall of the gas-liquid mixer and is located downstream of the water inlet and air inlet and upstream of the mixed fluid outlet. Multiple baffle holes are provided on the baffle plate, and the multiple baffle holes are irregularly distributed with the central axis of the gas-liquid mixer as the center.

[0076] A ring-shaped baffle is fixed to the inner wall of the gas-liquid mixer to agitate the gas-liquid mixture and enhance its mixing effect. The baffle is typically made of the same or compatible metal material as the gas-liquid mixer body, such as stainless steel, to ensure sufficient strength and corrosion resistance under high pressure and corrosive environments. The outer diameter of the baffle matches the inner wall diameter of the gas-liquid mixer and is fixed to the inner wall by welding or threaded connections, forming a ring-shaped baffle structure.

[0077] The baffle plate has multiple turbulence holes, irregularly distributed around the central axis of the gas-liquid mixer. This irregular distribution design creates complex turbulence as the fluid passes through the holes, increasing the contact area and collision opportunities between the gas and liquid phases, thereby further improving the mixing effect. The shape of the turbulence holes can be circular, square, or elliptical, and the specific hole diameter can be optimized according to parameters such as the diameter of the gas-liquid mixer and the operating pressure. The number of turbulence holes is not specifically limited and can be set according to the area of ​​the baffle plate and the mixing requirements. For example, 10-30 turbulence holes can be made on a baffle plate with a diameter of 100mm.

[0078] The baffle is located downstream of the water inlet and air inlet and upstream of the mixed fluid outlet, so that the high-pressure water and compressed air are initially mixed after entering the gas-liquid mixer, and then the mixing effect is further enhanced by the baffle. Finally, the mixed fluid flows out from the outlet, ensuring that the gas-liquid two-phase flow delivered to the main pipe 131 is a fully mixed gas-liquid two-phase flow.

[0079] In actual operation, after the high-pressure water and compressed air are initially mixed in the gas-liquid mixer, the mixed fluid flows towards the baffle plate. Due to the presence of irregularly distributed baffle holes on the baffle plate, the fluid is divided into multiple small streams as it passes through the baffle holes. These streams collide, cross, and mix with each other in the downstream area of ​​the baffle plate, forming strong turbulence. This turbulent state greatly increases the contact area between the gas and liquid phases and the intermolecular interactions, allowing the compressed air to be more evenly dispersed in the high-pressure water, forming finer and more uniform bubbles, thereby improving the quality and stability of the gas-liquid mixture. This enables the cleaning device to more effectively remove stubborn dirt from the roller surface, reducing the pressure and flow rate required for cleaning and reducing energy consumption. At the same time, the more uniform gas-liquid mixture also reduces local impact on the roller surface, lowers the risk of roller surface damage, extends the service life of the roller, further reduces equipment maintenance costs and downtime, and improves the production efficiency and economic benefits of the continuous casting machine.

[0080] According to some embodiments of this application, the secondary tube 132 is detachably connected to the main tube 131, and the nozzle 14 is detachably connected to the secondary tube 132.

[0081] The detachable connection between the secondary pipe 132 and the main pipe 131 allows for easy removal and installation of the secondary pipe 132 from the main pipe 131, facilitating equipment maintenance, replacement, and upgrades. Various structural forms of the detachable connection can be used. For example, a quick-connect coupling can be employed, typically consisting of a male and a female connector. The male connector is installed on the main pipe 131, and the female connector is installed on the secondary pipe 132. Quick connection and disconnection are achieved through insertion, removal, or rotation, and the connection features a sealing structure to prevent high-pressure water leakage. Alternatively, a flange connection can be used, with flanges welded to the ends of both the main pipe 131 and the secondary pipe 132, secured together with bolts, and a gasket placed between them for airtightness. A threaded connection can also be used, with matching internal and external threads at the connection ends of the main pipe 131 and the secondary pipe 132, tightened by rotation. Sealing tape can be wrapped around the threads to enhance sealing. The detachable connection point between the secondary pipe 132 and the main pipe 131 is usually located on the side of the main pipe 131, with multiple connection points spaced along the length of the main pipe 131 to accommodate multiple secondary pipes 132.

[0082] The detachable connection between nozzle 14 and sub-tube 132 also facilitates the replacement and maintenance of nozzle 14. The structure of the detachable connection can be similar to the connection structure between sub-tube 132 and main tube 131, for example, a threaded connection, where matching threads are provided at the tail of nozzle 14 and the end of sub-tube 132, and the connection is achieved by rotation and tightening; alternatively, a ferrule connection can be used, where a ferrule is installed at the end of sub-tube 132, and after nozzle 14 is inserted into the ferrule, the nozzle 14 is fixed by the locking mechanism of the ferrule. This connection method allows for quick and convenient installation and disassembly. To ensure a tight seal, a sealing gasket or O-ring is typically installed at the connection point between nozzle 14 and sub-tube 132.

[0083] During equipment use, nozzles 14 and secondary pipes 132 are components prone to wear and blockage. The detachable connection allows operators to quickly replace these components, reducing downtime and improving production efficiency. This design also facilitates equipment upgrades and modifications, such as replacing different types of nozzles 14 or adjusting the number and layout of secondary pipes 132 to meet varying cleaning needs. Furthermore, the detachable connection reduces maintenance costs, as only damaged parts need to be replaced, rather than the entire piping system.

[0084] This application also provides a continuous casting machine.

[0085] The continuous casting machine includes: a frame, multiple rollers, and a continuous casting machine sector section roller surface cleaning device 1 as described in any of the above technical solutions.

[0086] Multiple rollers are rotatably connected to the frame; a bracket 11 is mounted on the frame, and multiple nozzles 14 correspond to multiple rollers.

[0087] It should be noted that, since the continuous casting machine provided in this application embodiment includes the continuous casting machine sector section roller surface cleaning device 1 as described in any of the above technical solutions, it has the technical features and beneficial effects of the continuous casting machine sector section roller surface cleaning device 1 as described in any of the above technical solutions, which will not be repeated here.

[0088] The frame, as the basic support structure of the continuous casting machine, is used to install and secure the various components of the machine. The frame is typically made of high-strength metal materials, such as welded steel plates or spliced ​​steel sections, possessing sufficient strength and rigidity to withstand various loads during the continuous casting process. The structural form of the frame depends on the type and specifications of the continuous casting machine, generally including a bottom support frame, side frames, and a top frame, forming a complete rigid structure. The frame has multiple mounting positions and connection interfaces for installing components such as rollers and cleaning devices.

[0089] Multiple rollers are rotatably connected to the frame, serving to support and guide the movement of the billet within the continuous casting machine. The rollers are typically made of alloy steel or stainless steel, with special surface treatments to improve wear resistance and corrosion resistance. The number and arrangement of the rollers depend on the type of continuous casting machine and the production process. The rollers are rotatably connected to the frame via bearing seats and bearings, with the bearing seats fixed in corresponding positions within the frame to ensure flexible rotation of the rollers.

[0090] The bracket 11 of the cleaning device is fixed to the frame by bolts or welding to ensure the stability of the cleaning device during operation. Multiple nozzles 14 are arranged one-to-one with multiple rollers, and the nozzle of each nozzle 14 is aligned with the surface of the corresponding roller to ensure that the high-pressure water flow can be accurately sprayed onto the roller surface to achieve cleaning of the roller surface.

[0091] The continuous casting machine provided in the embodiments of this application can achieve online cleaning of the surface of the sector section rollers, effectively removing dirt from the roller surface and avoiding problems such as reduced roller cooling effect, increased roller surface temperature, and shortened equipment life caused by dirt accumulation. This not only improves the service life of the rollers and reduces equipment maintenance costs and downtime, but also improves the surface quality of the cast billet, reduces the generation of cast billet defects, and improves the stability and efficiency of continuous casting production.

[0092] According to some embodiments of this application, a buffer may be provided between the bracket 11 and the frame.

[0093] A buffer is installed between the support 11 and the frame to reduce the impact of vibrations generated during the continuous casting machine's operation on the cleaning device, especially ensuring the positional stability of key components such as the nozzle 14, and ensuring consistent cleaning results. The buffer can be made of materials with good elasticity and shock absorption properties, such as rubber-based buffers like natural rubber pads or nitrile rubber pads, which have excellent elastic recovery capabilities and can absorb vibration energy through their own deformation. Their shape can be adapted to the contact surfaces of the support 11 and the frame, such as rectangular or circular shapes. Alternatively, it can be an elastic metal component, such as a disc spring or wave spring. The metal material makes it suitable for high-temperature environments, buffering vibrations through elastic deformation. Two to four buffers can be evenly arranged circumferentially along the mounting holes of the support 11 to form multi-point buffering. Composite buffers, such as structures with rubber-wrapped metal frames, can also be used.

[0094] In actual operation, vibration is transmitted to the buffer component, which absorbs or converts the vibration energy through elastic deformation (such as the compression of rubber pads and the extension and contraction of springs), reducing the intensity of vibration transmitted to the cleaning device. This significantly improves the overall positional stability of the cleaning device, preventing the relative position of nozzle 14 and the roller surface from shifting due to vibration, and ensuring that the high-pressure water flow always accurately acts on the area to be cleaned on the roller surface. At the same time, the reduction in vibration also reduces fatigue wear on various components inside the cleaning device (such as pipeline connections and adjustment components) caused by vibration, extending the service life of the cleaning device, further reducing equipment maintenance costs, and ensuring the continuous and stable operation of the continuous casting machine.
