Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel production and processing technology, specifically to an anti-slip structure for strip steel during steel rolling. Background Technology
[0002] Steel rolling is a process in which steel billets (cast billets or forged billets) are rolled into steel products of the desired shape and size through a series of rolling mills. This process uses rolls to apply pressure to the metal, deforming it and reducing its cross-sectional area, thereby extending its length. Rolling can not only change the external dimensions of steel, but also improve its internal structure and enhance its mechanical properties.
[0003] Based on the above, the inventors have discovered the following problems: during the current rolling mill process, slippage between coils and slippage of the mandrel can cause slippage due to speed oversaturation. In particular, slippage of the mandrel is difficult to grind and replacement is very difficult and time-consuming. Therefore, once it occurs, it is difficult to deal with, and the only solution is to roll at low speed or change the material. The traditional solution is to directly modify the rolling mill speed. This solution can only be effective for a period of time. When slippage becomes more severe, it is also easy to cause loss of tension, which is not convenient to use.
[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a strip anti-slip structure in the steel rolling process, in order to achieve a more practical purpose. Utility Model Content
[0005] The purpose of this invention is to provide a strip anti-slip structure during steel rolling to solve the problems mentioned in the background art.
[0006] A strip anti-slip structure for steel rolling includes a rolling mill assembly. A control component is provided on one side of the rolling mill assembly. The rolling mill assembly includes a frame. Two work rolls are rotatably connected to the middle of the inner side of the frame. A speed sensor is provided at one end of each work roll. Mounting brackets are fixed on both sides of the frame. A laser velocimeter is fixedly installed inside the mounting brackets. The control component includes a drive box. A drive motor is fixedly installed on one side of the bottom of the drive box. A control panel is fixedly installed on one side of the top of the drive box. A microprocessor is provided inside the control panel. The control panel is electrically connected to the drive motor, the speed sensor, and the laser velocimeter.
[0007] By adopting the above technical solution, a control component is provided on one side of the rolling mill assembly, facilitating the control of the rolling mill assembly to roll the steel strip. The two work rolls, which directly contact the material being rolled, are responsible for applying pressure and plastic deformation to the metal. A speed sensor monitors the operating speed of the rolling mill assembly and generates an electrical signal of the rolling speed value. A laser tachometer monitors the actual running speed of the steel strip and generates an electrical signal of the steel strip speed value. A drive motor outputs power to control the rolling mill assembly to roll the material. The panel design facilitates control of the device's operation and allows for easy input of speed limit protection values. The microprocessor collects and compares the strip speed and mill speed values to determine if slippage occurs. When slippage occurs, a deviation value is generated and compared with the protection value. If the deviation value is less than or equal to the protection value, the drive motor is adjusted according to the deviation value; if the deviation value is greater than the protection value, the drive motor is adjusted according to the protection value. This provides real-time adjustment of the mill speed, effectively preventing situations where the set deviation change cannot keep up during speed increases, leading to desaturation. The protection value setting effectively prevents strip breakage and tension loss in the event of severe slippage. Furthermore, a guide roller is rotatably connected to one end of the mounting frame, located at the end of the mounting frame furthest from the machine frame.
[0008] By adopting the above technical solution and setting the guide rollers, the rolled steel strip can be easily guided, thereby improving the stability of steel strip rolling.
[0009] Furthermore, the top and bottom of the inner side of the mounting frame are rotatably connected to support rollers, and the two support rollers are respectively set at the top and bottom of the working roller.
[0010] By adopting the above technical solution, the support rollers facilitate the support of the work rolls, share part of the load, and reduce the bending deformation of the work rolls, thus ensuring stability and precision during the rolling process.
[0011] Furthermore, the drive box is equipped with a speed-changing gear set, the input end of which is fixedly connected to the output end of the drive motor.
[0012] By adopting the above technical solution and setting up a speed-changing gear set, it is easy to reduce the output speed of the drive motor, thereby increasing the output torque.
[0013] Furthermore, two drive shafts are rotatably connected to one side of the drive box, and the two drive shafts are fixedly connected to the output end of the speed change gear set.
[0014] By adopting the above technical solution and setting up a speed-changing gear set, it is easy to transmit the rotational power provided by the drive motor to the transmission shaft, thereby driving the support roller to rotate.
[0015] Furthermore, a coupling is fixedly installed at one end of the drive shaft, and the coupling is fixedly connected to the support roller.
[0016] By adopting the above technical solution and setting the coupling, it is easy for the rotation of the transmission shaft to drive the rotation of the support roller. The support roller transmits power, which can effectively distribute the load and prevent the working roller from being deformed or damaged due to directly bearing large torque.
[0017] Furthermore, a torque monitoring device and a torque overload protection device are provided between the coupling and the support roller.
[0018] By adopting the above technical solutions and installing torque monitoring and torque overload protection devices, the safety and reliability of the equipment can be improved, and mechanical damage caused by sudden excessive load can be avoided.
[0019] Furthermore, the control panel is also equipped with an alarm module and a remote communication module, which are electrically connected to the microprocessor.
[0020] By adopting the above technical solution, and by setting up an alarm module and a remote communication module, the alarm module can issue an alarm when the microprocessor detects strip slippage, excessive speed deviation, or motor overload. The remote communication module will upload the operating data to the central control system or remote monitoring platform to realize intelligent early warning and remote control functions.
[0021] Furthermore, an intermediate roller is provided between the support roller and the working roller, and the intermediate roller is rotatably connected to the frame.
[0022] By adopting the above technical solution and setting the intermediate roll, it is easier to reduce the vibration or jumping phenomenon that may be caused by the work roll directly bearing the full load, and the load is evenly distributed, which is conducive to enhancing rolling accuracy.
[0023] Compared with the prior art, the beneficial effects of this utility model are as follows: A control component is provided on one side of the rolling mill assembly, facilitating the control of the rolling mill assembly to roll the steel strip. The arrangement of two work rolls allows for direct contact between the two work rolls and the material being rolled, responsible for applying pressure and plastic deformation to the metal material. The inclusion of a speed sensor facilitates monitoring of the working speed of the rolling mill assembly and generating an electrical signal for the rolling speed value. The use of a laser tachometer facilitates monitoring of the actual running speed of the steel strip and generating an electrical signal for the steel strip speed value. The inclusion of a drive motor facilitates the output of power to control the rolling mill assembly to roll the material. The control panel facilitates the control of the device's operation and allows for easy input of speed limit protection values. The microprocessor collects and compares the strip speed and mill speed values to determine if slippage occurs. When slippage occurs, a deviation value is generated and compared with a protection value. If the deviation value is less than or equal to the protection value, the drive motor is adjusted according to the deviation value; if the deviation value is greater than the protection value, the drive motor is adjusted according to the protection value. This achieves real-time adjustment of the mill speed, effectively preventing desaturation caused by the set deviation not keeping up with the speed increase. The protection value setting effectively prevents strip breakage and loss of tension in the event of severe slippage. This invention provides real-time adjustment of the mill speed, effectively preventing desaturation caused by the set deviation not keeping up with the speed increase, and has high practical value.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figures 1-4 This utility model provides a technical solution: a strip anti-slip structure for steel rolling, including a rolling mill assembly 1. A control assembly 2 is provided on one side of the rolling mill assembly 1. The control assembly 2 facilitates the operation of the rolling mill assembly 1 to control the rolling of the steel strip. The rolling mill assembly 1 includes a frame 11, with two work rolls 16 rotatably connected to the center of the inner side of the frame 11. The two work rolls 16 are designed to directly contact the material being rolled, applying pressure and plastically deforming the metal. A speed sensor 15 is provided at one end of each work roll 16, allowing for monitoring of the working speed of the rolling mill assembly 1 and generating an electrical signal indicating the rolling speed value. Mounting brackets 12 are fixed on both sides of the frame 11, with laser velocimeters 14 fixedly installed inside each bracket. The laser velocimeters 14 facilitate monitoring of the actual running speed of the steel strip and generating an electrical signal indicating the steel strip speed value. The control assembly 2 includes a drive box 21, with a [missing information - likely a device or component] fixedly installed on one side of the bottom of the drive box 21. The drive motor 23 is configured to output power to control the operation of the rolling mill assembly 1 for rolling materials. A control panel 22 is fixedly installed on one side of the top of the drive box 21. The control panel 22 contains a microprocessor and is electrically connected to the drive motor 23, the speed sensor 15, and the laser velocimeter 14. The control panel 22 facilitates the control of the device's operation and allows for easy input of speed limit protection values. The microprocessor collects and compares the strip speed and the rolling mill speed to determine if slippage occurs. When slippage occurs, a deviation value is generated and compared with the protection value. If the deviation value is less than or equal to the protection value, the operation of the drive motor 23 is adjusted according to the deviation value. If the deviation value is greater than the protection value, the operation of the drive motor 23 is adjusted according to the protection value. This achieves real-time adjustment of the rolling mill speed, effectively preventing the situation where the set deviation change cannot keep up during speed increase, leading to desaturation. The protection value setting can effectively prevent the occurrence of tension loss and strip breakage in the event of severe slippage.
[0032] The mounting frame 12 has a guide roller 13 rotatably connected to one end. The guide roller 13 is located at the end of the mounting frame 12 away from the frame 11. The guide roller 13 facilitates the guidance of the rolled steel strip and improves the stability of the steel strip rolling.
[0033] The mounting frame 12 has two support rollers 17 rotatably connected to its inner top and bottom. The two support rollers 17 are respectively set at the top and bottom of the work roll 16. The support rollers 17 are used to support the work roll 16, share part of the load, and reduce the bending deformation of the work roll 16, thus ensuring the stability and accuracy during the rolling process.
[0034] The drive box 21 is equipped with a speed-changing gear set. The input end of the speed-changing gear set is fixedly connected to the output end of the drive motor 23. By setting the speed-changing gear set, it is easy to reduce the output speed of the drive motor 23, thereby increasing the output torque.
[0035] Two drive shafts 24 are rotatably connected to one side of the drive box 21. The two drive shafts 24 are fixedly connected to the output end of the speed change gear set. The speed change gear set facilitates the transmission of the rotational power provided by the drive motor 23 to the drive shafts 24, thereby driving the support roller 17 to rotate.
[0036] One end of the drive shaft 24 is fixedly equipped with a coupling 25, which is fixedly connected to the support roller 17. The coupling 25 facilitates the rotation of the drive shaft 24 to drive the support roller 17 to rotate. The support roller 17 transmits power and can effectively distribute the load, preventing the working roller 16 from being deformed or damaged due to directly bearing large torque.
[0037] Among them, a torque monitoring device and a torque overload protection device are provided between the coupling 25 and the support roller 17. The installation of the torque monitoring device and the torque overload protection device can improve the safety and reliability of the equipment and avoid mechanical damage caused by sudden excessive load.
[0038] The control panel 22 is equipped with an alarm module and a remote communication module. The alarm module and the remote communication module are electrically connected to the microprocessor. The alarm module can issue an alarm when the microprocessor detects strip slippage, excessive speed deviation, or motor overload. The remote communication module uploads the operating data to the central control system or remote monitoring platform to realize intelligent early warning and remote control functions.
[0039] An intermediate roll 18 is provided between the support roll 17 and the work roll 16. The intermediate roll 18 is rotatably connected to the frame 11. The intermediate roll 18 helps to reduce the vibration or jumping phenomenon that may be caused by the work roll 16 directly bearing the full load, and the load is evenly distributed, which is conducive to enhancing the rolling accuracy.
[0040] Specifically, the working principle of this anti-slip structure for steel strip during the steel rolling process is as follows: During use, the speed sensor 15 facilitates monitoring of the working speed of the rolling mill assembly 1 and generates an electrical signal for the rolling mill speed value. The laser tachometer 14 facilitates monitoring of the actual running speed of the steel strip and generates an electrical signal for the steel strip speed value. The control panel 22 facilitates control of the device's operation and allows for easy input of speed limit protection values. The microprocessor collects and compares the steel strip speed value and the rolling mill speed value to determine if slippage occurs. When slippage occurs, a deviation value is generated, and this deviation value is then compared with the protection value. When the deviation value is less than... When the deviation value equals the protection value, the operation of the drive motor 23 is adjusted according to the deviation value. When the deviation value exceeds the protection value, the operation of the drive motor 23 is adjusted according to the protection value, thereby achieving real-time adjustment of the mill speed. This effectively avoids the situation where the set deviation change cannot keep up during speed increase, leading to desaturation. The protection value setting can effectively prevent loss of tension and strip breakage in the event of severe slippage. The setting of the drive motor 23 facilitates the output power control of the drive motor 23 to control the operation of the mill assembly 1 to roll the material. The setting of the speed change gear set facilitates the reduction of the output speed of the drive motor 23, thereby increasing the output torque. The configuration facilitates the transmission of rotational power from the drive motor 23 to the transmission shaft 24, thereby driving the support roller 17 to rotate. The coupling 25 further facilitates the rotation of the transmission shaft 24, which in turn drives the support roller 17. The support roller 17 transmits power, effectively distributing the load and preventing the work roller 16 from deforming or being damaged due to directly bearing large torques. The torque monitoring device and torque overload protection device enhance the safety and reliability of the equipment, preventing mechanical damage caused by sudden excessive loads. The support roller 17 also supports the work roller 16, sharing some of the load and reducing bending deformation of the work roller 16, ensuring smooth operation during the rolling process. The stability and precision of the rolling mill are enhanced by the arrangement of two work rolls 16, which are directly in contact with the rolled material and are responsible for applying pressure and plastic deformation to the metal material. The alarm module and remote communication module enable the alarm module to issue an alarm when the microprocessor detects strip slippage, excessive speed deviation, or motor overload. The remote communication module uploads the operating data to the central control system or remote monitoring platform to realize intelligent early warning and remote control functions. The intermediate roll 18 reduces the vibration or jumping phenomenon that may be caused by the work rolls 16 directly bearing the full load, and the uniform load distribution helps to enhance rolling accuracy.
