Description

Technical Field

[0001] This invention belongs to the technical field of hot rolling production, and specifically relates to a guiding device and hot rolling production line based on hot-rolled high-grade silicon steel. Background Technology

[0002] High-grade silicon steel, especially silicon steel with high silicon content (such as 6.5% Si), has become an indispensable core material in fields such as new energy vehicle drive motors, high-efficiency energy-saving transformers, and ultra-high voltage power transmission and transformation equipment due to its excellent soft magnetic properties, including low iron loss, high magnetic permeability, and low magnetostriction. With the continuous growth in demand for high-grade silicon steel from high-end manufacturing industries, the requirements for its product quality, especially edge quality and dimensional accuracy, are becoming increasingly stringent. However, the production of high-grade silicon steel, particularly in the hot rolling process, is challenging due to the high content of alloying elements such as silicon, manganese, and aluminum. During high-temperature deformation, the material easily forms ordered phases such as B2 and D03, leading to a significant reduction in plasticity, increased room-temperature brittleness, and a narrow hot rolling process window. Therefore, during hot rolling, strip steel is highly susceptible to quality problems such as edge cracking, deviation, and edge scratches, severely restricting production efficiency and product yield. This places higher technical demands on the guiding and centering devices on the hot rolling production line.

[0003] Currently, most common guide and centering devices on hot rolling production lines employ a guide structure where the guide plate forms a surface contact with the edge of the strip. During the hot rolling of high-grade silicon steel, this contact method easily creates stress concentration areas at the strip edge, accompanied by sliding friction, leading to stress damage and potentially inducing or amplifying edge cracks. It also causes scratches and burrs on the strip edge. Furthermore, guide and centering devices often use fixed gaps or single pressure control modes for centering adjustment. However, during the rolling of high-grade silicon steel, the temperature and width of the strip fluctuate dynamically, making it difficult for this control method to adapt to these dynamic changes, which can also lead to strip misalignment and centering deviations. Summary of the Invention

The motor has its output shaft connected to one end of the worm gear.

[0009] Preferably, the linear drive unit further includes an encoder, which is mounted on the output shaft end of the motor and is used to detect the speed and angle signals of the motor.

[0010] Preferably, each of the roller frames comprises: A bent plate, one end of which is connected to the corresponding slider; An inner sleeve is fitted onto the end of the corresponding roller shaft away from the conveying roller body via the bearing; An outer sleeve is fixedly fitted outside the inner sleeve and connected to the other end of the bent plate.

[0011] Preferably, the roller frame further includes a support mounting assembly, the support mounting assembly comprising: The lower end cover is disposed on one end of the inner sleeve near the guide roller body and is fixedly connected to the inner sleeve.

[0016] Beneficial technical effects of the present invention: This invention discloses a guiding device for hot-rolled high-grade silicon steel. A pair of guide roller bodies are respectively positioned on both sides of a conveyor roller body, with their axial directions perpendicular to the conveyor roller body's axial direction. This allows the guide roller bodies to form rolling contact with the side edges of the strip. Compared to surface contact guiding methods, rolling contact significantly reduces the contact area and frictional resistance, effectively preventing stress concentration at the strip edges. This suppresses the generation and propagation of edge cracks during the hot rolling of high-grade silicon steel, while also reducing surface quality issues such as edge scratches and burrs, thus improving product yield. Furthermore, a drive mechanism is connected to the pair of guide roller bodies, enabling them to move synchronously closer or further away along the axial direction of the conveyor roller body. This allows for real-time adjustment of the guide spacing, ensuring the strip remains precisely aligned throughout the rolling process and preventing deviations and centering issues caused by dynamic changes in strip width. Therefore, this invention improves guiding accuracy and strip edge quality while reducing equipment wear and downtime, thus enhancing production continuity and operational efficiency.

[0022] It should be noted that the terms "a" and "a plurality of" used in this invention are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0023] To address the problems existing in the aforementioned related technologies, the present invention provides a guiding device and hot rolling production line based on hot-rolled high-grade silicon steel, which will be described in detail below with reference to specific embodiments.

[0024] See Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a guiding device for hot-rolled high-grade silicon steel, comprising a conveying roller mechanism 1, a pair of guide roller bodies 2, and a driving mechanism 3. The conveying roller mechanism 1 is used to support and convey strip steel and includes a conveying roller body 11. The pair of guide roller bodies 2 are respectively disposed on both sides of the conveying roller body 11, and the axial direction of the guide roller bodies 2 is perpendicular to the axial direction of the conveying roller body 11. The pair of guide roller bodies 2 are used to roll in contact with the two sides of the strip steel. The driving mechanism 3 is connected to the pair of guide roller bodies 2 and is used to drive the pair of guide roller bodies 2 to move closer to or further away from the conveying roller body 11 along the axial direction to adjust the spacing between the pair of guide roller bodies 2.

[0025] It should be noted that a pair of guide roller bodies 2 are respectively disposed on both sides of the conveyor roller body 11, and the axial direction of the guide roller bodies 2 is perpendicular to the axial direction of the conveyor roller body 11, so that the guide roller bodies 2 form rolling contact with the edge of the strip. Compared with the surface contact method between the guide plate and the edge of the strip in the prior art, this structural feature changes sliding friction to rolling contact, which significantly reduces the contact area and frictional resistance, avoids the formation of stress concentration areas at the edge of the strip, and thus effectively suppresses the generation and expansion of edge crack defects during the hot rolling of high-grade silicon steel, while also reducing surface quality problems such as edge scratches and burrs. On the other hand, the drive mechanism 3 is connected to the pair of guide roller bodies 2, and can drive the pair of guide roller bodies 2 to move synchronously closer or further away along the axial direction of the conveyor roller body 11, thereby adjusting the guide spacing in real time according to the dynamic changes in the strip width. This driving method ensures that the strip is always in a precise centering state during the rolling process, avoiding deviation and centering misalignment problems. Furthermore, this embodiment eliminates complex transmission structures such as gear racks or crank connecting rods, resulting in a simple and compact overall structure. The equipment is lightweight and occupies a small area, reducing investment costs and daily maintenance difficulties for the production line. Simultaneously, because the guide roller body 2 makes rolling contact with the strip edge, friction loss is reduced, extending the device's service life, minimizing downtime due to equipment wear, and improving production continuity and operational efficiency.

[0026] In summary, this invention addresses the material properties of high-grade silicon steel and its hot rolling process requirements by improving various aspects such as contact method, control method, equipment structure, and service life. It effectively solves problems such as edge crack damage, centering deviation, complex structure, and severe wear existing in the prior art.

[0027] In one embodiment of the present invention, the drive mechanism 3 includes a pair of roller frames 31, a pair of roller shafts 32, and a linear drive unit. A pair of guide roller bodies 2 are fixedly sleeved on the corresponding pair of roller shafts 32, and the roller shafts 32 are rotatably mounted on the roller frames 31 via bearings 315; the linear drive unit is connected to the pair of roller frames 31 and is used to drive the pair of roller frames 31 to move axially along the conveying roller body 11.

[0028] It should be noted that in this embodiment, a pair of guide roller bodies 2 are fixedly sleeved on corresponding roller shafts 32, and the roller shafts 32 are rotatably mounted on the roller frame 31 via bearings 315. This structure allows the guide roller bodies 2 to rotate freely relative to the roller frame 31, forming a stable rolling fit when in contact with the edge of the strip, further reducing contact resistance and friction loss, and avoiding stress damage and surface scratches on the strip edge caused by sliding friction. Simultaneously, a linear drive unit is connected to the pair of roller frames 31, enabling them to move synchronously along the axial direction of the conveying roller body 11, achieving precise adjustment of the guide spacing. Since the roller frame 31 is an independent load-bearing unit, its structural design ensures a stable and reliable installation position for the guide roller bodies 2, maintaining good alignment even when subjected to lateral impact forces from the strip. Furthermore, the rotational fit between the roller shaft 32 and the roller frame 31 via bearings 315 makes maintenance and replacement of the guide roller bodies 2 more convenient, reducing downtime. As can be seen, this embodiment has systematically optimized the installation method and rotational fit of the guide rollers to the overall drive layout, which not only ensures the stability and centering accuracy of the guiding process, but also reduces wear and maintenance costs during equipment operation.

[0029] In one embodiment of the present invention, the linear drive unit includes a guide rail 331, a pair of sliders 332, a worm gear 333, and a motor 334. The guide rail 331 is arranged along the axial direction of the conveying roller body 11. The pair of sliders 332 are slidably mounted on the guide rail 331 and connected to a corresponding pair of roller frames 31. The worm gear 333 is arranged parallel to the guide rail 331. The worm gear 333 has a first threaded section and a second threaded section with opposite directions of rotation on its shaft. The first threaded section is threadedly connected to one slider 332, and the second threaded section is threadedly connected to the other slider 332. The output shaft of the motor 334 is drively connected to one end of the worm gear 333.

[0030] It should be noted that in this embodiment, the guide rail 331 is arranged along the axial direction of the conveying roller body 11, and a pair of sliders 332 are slidably mounted on the guide rail 331 and connected to the corresponding roller frame 31. This structure provides a stable guiding foundation for the linear movement of the roller frame 31, ensuring the stability and positional accuracy of the guide roller body 2 during movement. The worm gear 333 is arranged parallel to the guide rail 331, and its shaft is provided with a first thread section and a second thread section with opposite directions of rotation, which are threadedly connected to the two sliders 332 respectively. When the motor 334 drives the worm gear 333 to rotate, the two sliders 332 synchronously generate linear movements in opposite directions under the constraint of the guide rail 331, thereby driving the pair of guide roller bodies 2 to synchronously move closer or further away. This synchronization method, which uses a single motor 334 to drive and a worm gear with dual-direction thread transmission, has the advantages of simple structure, high synchronization accuracy, and fast response speed compared to the traditional technical solution that uses two independent drive units or complex linkage mechanisms. It effectively avoids the problems of strip deviation and centering deviation caused by asynchronous movement on both sides. Meanwhile, the threaded transmission between the worm gear 333 and the slider 332 has a self-locking characteristic, which can maintain a stable position after adjustment, eliminating the need for an additional locking mechanism and further simplifying the equipment structure. The sliding engagement between the guide rail 331 and the slider 332 results in low motion resistance and high guiding accuracy, ensuring the centering accuracy of the guide roller body 2 even under complex working conditions such as strip temperature fluctuations and impact load changes. Therefore, this embodiment achieves precise synchronous adjustment of the guide roller body 2 through the coordinated configuration of the guide rail, slider, double-rotating worm gear, and motor 334. This not only solves the problems of control methods being difficult to adapt to dynamic changes and large centering deviations, but also reduces equipment complexity and floor space through structural simplification, while reducing wear on moving parts and extending the equipment's service life.

[0031] In one embodiment of the present invention, the linear drive unit further includes an encoder, which is mounted on the output shaft end of the motor 334 and is used to detect the speed and angle signals of the motor 334.

[0032] It should be noted that the encoder in this embodiment is installed on the output shaft of the motor 334, which can detect the speed and angle signals of the motor 334 in real time, providing precise position feedback for the drive system. This technical feature, in conjunction with the aforementioned threaded transmission between the worm gear 333 and the slider 332, forms a closed-loop control system: when it is necessary to adjust the distance between a pair of guide roller bodies 2, the control system precisely controls the rotation amount and direction of the motor 334 according to the deviation between the target position and the actual position fed back by the encoder, ensuring that the slider 332 moves to the preset position, thereby achieving precise adjustment of the guide distance. This improves the repeatability and dynamic response performance of the guide alignment device. In the hot rolling process of high-grade silicon steel, the temperature, width, and deviation trend of the strip are in dynamic change. The introduction of the encoder enables the control system to monitor the actual position of the guide roller body 2 in real time and make timely fine adjustments according to the changes in the strip state, ensuring that the guide roller body 2 always maintains an appropriate contact state with the edge of the strip, neither too tight, which would cause edge stress damage, nor too loose, which would cause alignment failure.

[0033] In one embodiment of the present invention, each roller frame 31 includes a bent plate 311, an inner sleeve 312 and an outer sleeve 313. One end of the bent plate 311 is connected to the corresponding slider 332. The inner sleeve 312 is sleeved on the end of the corresponding roller shaft 32 away from the conveying roller body 11 through a bearing 315. The outer sleeve 313 is fixedly sleeved on the outside of the inner sleeve 312 and is connected to the other end of the bent plate 311.

[0034] It should be noted that the bent plate 311 in this embodiment serves as an intermediate load-bearing structure connecting the slider 332 and the outer sleeve 313. Its bent shape not only adapts to spatial layout requirements, making the transmission path of driving force smoother, but also possesses a certain structural rigidity, effectively withstanding the lateral impact force of the strip steel and avoiding alignment deviation caused by deformation under stress. The inner sleeve 312 is fitted onto the end of the roller shaft 32 furthest from the conveying roller body 11 via a bearing 315. This design allows the roller shaft 32 to rotate freely relative to the inner sleeve 312, ensuring a stable rolling fit when the guide roller body 2 contacts the edge of the strip steel. Simultaneously, the radial load is transmitted to the inner sleeve 312 via the bearing 315, and then to the entire roller frame 31. The outer sleeve 313 is fixedly fitted onto the outside of the inner sleeve 312 and connected to the other end of the bent plate 311, forming a double sleeve structure. This enhances the rigidity and bending resistance of the roller shaft 32 mounting area, preventing deformation or deflection when subjected to large lateral forces.

[0035] In one embodiment of the present invention, the roller frame 31 further includes a support mounting assembly, which includes a lower end cover 3141, an upper end cover 3142, a positioning ring 3143, and a locking nut 3144. The lower end cover 3141 is disposed on one end of the inner sleeve 312 near the guide roller body 2 and is fixedly connected to the inner sleeve 312. The upper end cover 3142 is disposed on the other end of the inner sleeve 312. The positioning ring 3143 is fixedly sleeved on the roller shaft 32, and a sealing element is provided between the positioning ring 3143 and the upper end cover 3142. The locking nut 3144 is threadedly connected to the end of the roller shaft 32 that extends out of the upper end cover 3142, and a backstop washer 3145 is provided between the locking nut 3144 and the upper end cover 3142.

[0036] It should be noted that this embodiment improves the sealing reliability, axial positioning accuracy, and operational stability of the bearing 315 inside the roller frame 31 through the specific structural configuration of the support and mounting components. Specifically, the lower end cover 3141 is installed on one end of the inner sleeve 312 near the guide roller body 2 and is fixedly connected to the inner sleeve 312, while the upper end cover 3142 is installed on the other end of the inner sleeve 312. Together, they form a closed receiving space, encapsulating the bearing 315 inside the inner sleeve 312. This effectively isolates impurities such as iron oxide scale, cooling water, and dust from the external environment, preventing wear and jamming of the bearing 315 caused by impurities and extending the service life of the bearing 315. The positioning ring 3143 is fixedly sleeved on the roller shaft 32, and a seal is provided between it and the upper end cover 3142. This structure not only achieves axial positioning of the roller shaft 32 relative to the inner sleeve 312, preventing the roller shaft 32 from moving under axial impact loads, but also further enhances the sealing effect between the upper end cover 3142 and the roller shaft 32 through the seal, forming multiple layers of protection. The locking nut 3144 is threaded to the end of the roller shaft 32 that extends out of the upper end cover 3142, and is locked to the upper end cover 3142 by a backstop washer 3145. This configuration ensures that the locking nut 3144 will not loosen under long-term vibration conditions, maintaining the axial preload of the roller shaft 32 and avoiding increased bearing clearance and decreased guiding accuracy due to loosening. In addition, the setting of the backstop washer 3145 makes the anti-loosening effect of the locking nut 3144 more reliable, eliminating the need for frequent inspection and tightening, and reducing maintenance workload. As can be seen, this embodiment ensures the long-term stable operation and precise centering performance of the guide roller body 2 under high-speed and heavy-load conditions.

[0037] In one embodiment of the present invention, each guide roller body 2 includes an inner roller body 21, an outer roller body 22, multiple connecting plates 23, and a buffer layer 24. The inner roller body 21 is fixedly sleeved on the end of the corresponding roller shaft 32 near the conveying roller body 11. The outer roller body 22 is coaxially sleeved on the outside of the inner roller body 21. The multiple connecting plates 23 are axially spaced between the inner roller body 21 and the outer roller body 22 for connecting the inner roller body 21 and the outer roller body 22. The buffer layer 24 is disposed on the outer peripheral surface of the outer roller body 22.

[0038] It should be noted that in this embodiment, the inner roller body 21 is fixedly sleeved on the end of the roller shaft 32 near the conveying roller body 11, serving as the load-bearing base of the entire guide roller body 2, ensuring the connection strength and torque transmission reliability with the roller shaft 32; the outer roller body 22 is coaxially sleeved on the outside of the inner roller body 21, and the two are connected axially at intervals by multiple connecting plates 23, forming a lightweight frame-like structure. This design not only effectively reduces the overall rotational inertia of the guide roller body 2 and reduces driving energy consumption, but also allows the outer roller body 22 to uniformly transfer the load to the inner roller body 21 and the roller shaft 32 through the connecting plates 23 when subjected to lateral impact from the strip, avoiding local stress concentration and improving the structure's impact resistance and operational stability. The multiple connecting plates 23 are spaced axially, ensuring a reliable connection between the inner roller body 21 and the outer roller body 22 while also forming a hollow area, which is beneficial for heat dissipation and weight reduction, avoiding roller deformation caused by heat accumulation. The buffer layer 24 is disposed on the outer peripheral surface of the outer roller body 22. As a component that directly contacts the edge of the strip, its material has appropriate elasticity and wear resistance. When it rolls in contact with the edge of the strip, it can play a buffering and vibration-absorbing role, further dispersing the contact stress and avoiding damage to the brittle edge of the strip caused by rigid contact. At the same time, the buffer layer 24 has a low coefficient of friction, which helps to reduce the sliding friction resistance of the strip edge and reduce the risk of edge scratches and burrs.

[0039] In one embodiment of the present invention, the conveying roller mechanism 1 further includes a cooling component. The conveying roller body 11 is a sleeve roller structure. The conveying roller body 11 has a cooling channel inside. The cooling component is connected to the cooling channel and is used to water cool the conveying roller body 11.

[0040] It should be noted that the conveyor roller body 11 in this embodiment, as a key component directly bearing and conveying high-temperature strip steel, absorbs a large amount of heat during long-term continuous operation. If heat dissipation is not timely, thermal expansion and deformation can easily occur, thereby affecting the running stability and guiding alignment accuracy of the strip steel. In this embodiment, the conveyor roller body 11 is configured as a sleeve roller structure with a cooling channel inside. The cooling component is connected to the cooling channel and cool water is introduced into it to achieve forced water cooling of the conveyor roller body 11. This allows the cooling water to circulate inside the conveyor roller body 11, evenly removing the heat accumulated in the roller, effectively controlling the roller body temperature within a reasonable range, and avoiding unevenness of the roller surface or axial misalignment caused by thermal deformation, thereby ensuring the stability of the strip steel during conveying and the stability of the alignment reference.

[0041] In one embodiment of the present invention, the guiding device based on hot-rolled high-grade silicon steel further includes a pair of frames 4, the conveying roller body 11 and the worm gear 333 are respectively rotatably mounted on the pair of frames 4, and a torque arm 41 is also hinged to the frame 4 by a pin, and the torque arm 41 is fixedly connected to the housing of the motor 334.

[0042] It should be noted that in this embodiment, the two ends of the conveyor roller body 11 and the worm gear 333 are rotatably mounted on the same pair of frames 4, avoiding the deviation in axis parallelism caused by independent installation. This ensures the transmission accuracy between the worm gear 333 and the guide rail 331 and slider 332, thus providing a stable structural foundation for precise alignment adjustment. At the same time, integrating the core transmission components onto the same frame 4 makes the entire drive unit structure more compact, reducing the workload of on-site installation and commissioning, and improving equipment installation efficiency.

[0043] A torque arm 41 is hinged to the frame 4 via a pin. The other end of the torque arm 41 is fixedly connected to the housing of the motor 334. When the motor 334 drives the worm gear 333 to rotate, the motor housing itself will be subjected to a reverse torque. If the housing is not constrained, the motor 334 will rotate or vibrate as a whole, affecting transmission accuracy and equipment safety. By connecting the motor housing to the frame 4 via the torque arm 41 and using a pin hinge, the rotational freedom of the motor 334 can be constrained, while allowing the motor 334 a certain radial float, avoiding additional stress and installation errors caused by rigid connections. The design of the torque arm 41 ensures that the reverse torque of the motor 334 is reliably transmitted to the frame 4, guaranteeing the smooth operation of the motor 334, reducing vibration and noise, and extending the service life of the motor 334 and its transmission components.

[0044] Furthermore, as the load-bearing foundation of the entire device, the structural rigidity and stability of the frame 4 directly affect the guiding and centering accuracy. In this embodiment, by integrating the conveyor roller body 11, worm gear 333, motor 334, and torque arm 41 onto the frame 4, a unified force-bearing system is formed. This makes the load transfer path between the various functional modules of strip conveying, guiding adjustment, and power drive clearer, avoiding the relative displacement and deformation problems that may occur with multiple foundation installations.

[0045] The present invention also includes a hot rolling production line, comprising the guide device based on hot-rolled high-grade silicon steel as described above. The beneficial effects compared to the prior art are the same as those of the guide device based on hot-rolled high-grade silicon steel described above, and will not be repeated here.

[0046] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
