Technical Field
[0001] The present invention relates to the field of automatic control technology, and in particular to a steel rolling system and method based on automatic push-bed measurement and intelligent control. Background Art
[0002] With the rapid development of the steel industry, the rolling accuracy, production efficiency and automation of steel have become the key to improving the competitiveness of enterprises. At present, automated steel rolling equipment is widely used in steel production, but there is still a lack of intelligent automatic control systems for automatic adjustment of the pusher position, steel clamping judgment, steel turning judgment and pass judgment. In addition, in the traditional steel rolling process, operators need to manually fill in the width of the steel, and adjust the position of the pusher and judge the rolling pass based on experience. However, this method has the problems of insufficient accuracy and low efficiency, especially in the continuous rolling process, unreliable manual operation is easy to lead to deviations in the rolling quality of steel; therefore, it does not meet the existing needs. In this regard, we propose a steel rolling system and method based on automatic pusher measurement and intelligent control. Summary of the invention
[0003] The object of the present invention is to provide a steel rolling system and method based on automatic push bed measurement and intelligent control, which solves the problems raised in the above-mentioned background technology by combining push bed positioning, width measurement, steel turning judgment and rolling pass monitoring in a parallel task queue to make each process seamlessly connected, and through a real-time operating system, ensure the synchronization and efficient execution of each process.
[0004] To achieve the above object, the present invention provides the following technical solutions: a steel rolling system based on automatic push bed measurement and intelligent control, comprising a steel rolling system and a push bed, wherein the push bed is equipped with a built-in sensor, and the steel rolling system uses the built-in sensor to monitor the current and torque changes of the push bed at different widths in real time, and the sensor can record the peak values of the current and torque, thereby automatically deriving the width of the steel through a preset threshold;
[0005] The push bed includes a transmission side push bed and an operating side push bed. The transmission side push bed automatically moves to a designated position through a positioning system, and the operating side push bed automatically adjusts its position according to the real-time width of the steel and the position of the transmission side push bed.
[0006] The steel rolling system automatically determines whether it is necessary to move the operating side pusher backward according to the width range of the steel to perform the steel turning operation. During the steel turning process, the steel rolling system can adjust the position of the steel turning support mechanism and the anti-fall mechanism, and the steel turning support mechanism is hydraulically driven;
[0007] After the steel is turned over, the steel rolling system measures the width of the steel again and adjusts the positions of the push bed on the transmission side and the push bed on the operating side to ensure that the push bed is in the optimal operating position during the next rolling process. The rolling process includes the main rolling mill, the working roller table and the frame roller table. By monitoring the current changes of the main rolling mill, the steel rolling system can automatically determine whether each rolling pass is completed to ensure that each pass is completed in a timely manner.
[0008] Furthermore, the sensor on the stretcher is a current or torque sensor, which can monitor the current and torque changes of the stretcher at different widths in real time.
[0009] Furthermore, a detection module is installed on the sensor, which monitors the temperature change and vibration of the sensor in real time. The real-time health status information of the sensor is understood based on the monitored information to determine whether the sensor is faulty. When the sensor is faulty, an alarm is immediately issued.
[0010] Furthermore, the positioning system of the transmission lateral push bed adopts a closed-loop control feedback mechanism, and a communication module is provided between the transmission lateral push bed and the operating lateral push bed, and the operating lateral push bed exchanges data with the transmission lateral push bed through the communication module.
[0011] Furthermore, the communication module has an anti-interference function. When exchanging data, the communication module monitors the signal quality in real time to determine whether the communication module is interfered with, and automatically adjusts the sending strategy in the event of interference, including increasing the number of repetitions or changing the sending frequency.
[0012] Furthermore, the main rolling mill is provided with a current sensor, which continuously monitors the pattern of current change during each rolling process and compares it with the preset pass completion standard. When it is detected that the current reaches the preset standard, the steel rolling system automatically confirms that the pass has been completed and transmits the signal back to the control center to trigger the next rolling process.
[0013] An implementation method of a steel rolling system based on automatic push bed measurement and intelligent control comprises the following steps:
[0014] When the rolling system is started, the front and rear positions and the pressing position of the pusher will be automatically initialized, and the position status of each mechanical component will be confirmed through sensors;
[0015] When receiving the steel incoming signal, the rolling system determines whether the transmission side pusher needs to be directly positioned according to the pass table and the steel width range;
[0016] If direct positioning is required, the transmission side pusher will automatically move to the steel turning waiting position, and the rolling system will automatically adjust the roller gap according to the state of the steel;
[0017] After the push bed clamps the steel, the rolling system calculates the precise width of the steel by measuring the current and torque of the push bed in the clamping state, and adjusts the final position of the push bed according to the data;
[0018] During the steel turning process, the operating side pusher retreats to the steel turning waiting position while clamping the steel. Then, the driving side pusher performs the steel turning operation, ensuring that the steel will not fall over or become unstable during the steel turning process by moving;
[0019] The rolling system continuously monitors the position of the pusher and the state of the steel during the rolling process to ensure the safety and stability of the entire process;
[0020] After the steel is turned, the rolling system measures the width of the steel again and adjusts the position of the pusher on the transmission side and the pusher on the operating side according to the latest data to ensure that the pusher is in the optimal operating position during the next rolling process;
[0021] After the main rolling mill, working roller table and frame roller table are started, the rolling system monitors the current status of the main rolling mill in real time during the rolling process. Through the current signal, the rolling system automatically determines whether the steel is successfully bitten into the main rolling mill and whether the current rolling pass is completed to ensure the timely completion of each pass.

BRIEF DESCRIPTION OF THE DRAWINGS
[0028] Figure 1 This is a control flow chart of the steel rolling system based on automatic push-bed measurement and intelligent control of the present invention. DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0030] In order to solve the problem that the existing steel rolling equipment lacks intelligent automatic control system, and in the traditional steel rolling process, the operator needs to manually fill in the width of the steel, and adjust the position of the pusher and judge the rolling pass according to experience. This method has technical problems such as insufficient accuracy and low efficiency. Please refer to Figure 1 , this embodiment provides the following technical solutions:
[0031] A steel rolling system based on automatic push bed measurement and intelligent control includes a steel rolling system and a push bed. The push bed is equipped with a built-in sensor. The steel rolling system uses the built-in sensor to monitor the current and torque changes of the push bed at different widths in real time, and the sensor can record the peak values of the current and torque, thereby automatically deriving the width of the steel through a preset threshold value.
[0032] Among them, the sensor on the stretcher is a current or torque sensor, which can monitor the current and torque changes of the stretcher at different widths in real time.
[0033] The technical effect of the above content is: by squeezing the steel through the push bed, the sensor on the push bed senses and records the changing values within the width range of the steel, so that the steel rolling system can automatically deduce the width of the steel through a pre-set threshold, thereby avoiding errors when manually filling in the width and effectively preventing inaccuracies in manual measurement.
[0034] The push bed includes a transmission side push bed and an operating side push bed. The transmission side push bed automatically moves to the specified position through the positioning system, and the operating side push bed automatically adjusts its position according to the real-time width of the steel and the position of the transmission side push bed.
[0035] The technical effect of the above content is: the transmission side push bed can automatically move to the designated position through the positioning system, and the operating side push bed can automatically adjust its position according to the real-time width of the steel and the position of the transmission side push bed. Through the above operation, the reasonable coordination between the operating side push bed and the transmission side push bed can be ensured, so that the push bed can stably support and push the steel to the correct position.
[0036] The steel rolling system automatically determines whether the operating side push bed needs to be retreated according to the width range of the steel in order to perform the steel turning operation. During the steel turning process, the steel rolling system can adjust the position of the steel turning support mechanism and the anti-fall mechanism. The steel turning support mechanism is hydraulically driven. After the steel turning is completed, the steel rolling system measures the width of the steel again and adjusts the position of the transmission side push bed and the operating side push bed to ensure that the push bed is in the optimal operating position during the next rolling process. The rolling process includes the main rolling mill, the working roller table and the frame roller table. By monitoring the current changes of the main rolling mill, the steel rolling system can automatically determine whether each rolling pass is completed to ensure that each pass is completed in a timely manner.
[0037] The technical effect of the above content is: the steel rolling system determines the necessity of steel turning through the rolled piece width data. If the steel width exceeds the preset range, the operating side push bed will automatically move back to release enough space for the transmission side push bed to perform the steel turning action. In addition, during the steel turning process, the steel rolling system can adjust the position of the steel turning support mechanism and the anti-fall mechanism to ensure the balance of the steel according to the feedback control during the turning process, thereby ensuring the stability and safety of the steel during turning. After the steel turning is completed, the steel rolling system can decide which side to use according to the position of the transmission side push bed. One side push bed performs the steel-beating operation. At this time, the rolling system will measure the width of the steel again and adjust the position of the transmission side push bed and the operating side push bed according to the latest data, so as to ensure that the push bed is in the optimal operating position during the next rolling process. When the main rolling mill, working roller table and frame roller table are started, the rolling system can monitor the current status of the main rolling mill in real time during the rolling process, so that the rolling system can automatically determine whether the steel is successfully bitten into the main rolling mill and whether the current rolling pass is completed through the current signal. The mechanism of the main rolling mill in real time during the rolling process ensures the timely completion of each pass and avoids unnecessary pauses and delays.
[0038] The sensor is equipped with a detection module, which monitors the temperature change and vibration of the sensor in real time. The real-time health status of the sensor is understood based on the monitored information to determine whether the sensor is faulty. When the sensor is faulty, an alarm is immediately issued.
[0039] The technical effect of the above content is: by installing the detection module, various parameters of the sensor can be monitored in real time, and an alarm will be issued when an abnormality occurs, promptly reminding the operator to take measures to prevent potential risks, thereby helping to increase the service life of the sensor.
[0040] The positioning system of the transmission side push bed adopts a closed-loop control feedback mechanism, and a communication module is provided between the transmission side push bed and the operating side push bed, and the operating side push bed exchanges data with the transmission side push bed through the communication module.
[0041] The communication module has anti-interference function. When exchanging data, the communication module monitors the signal quality in real time to determine whether the communication module is interfered with. In the event of interference, it automatically adjusts the sending strategy, including increasing the number of repetitions or changing the sending frequency.
[0042] The technical effects of the above content are as follows: the closed-loop control feedback mechanism can improve the positioning accuracy and efficiency of the transmission side pusher, so that the transmission side pusher can work more accurately and efficiently, ensuring that the transmission side pusher is accurately positioned to the predetermined point each time, and setting up a communication module between the transmission side pusher and the operating side pusher, so that real-time data exchange can be carried out between the two, which greatly improves the intelligence level and work efficiency of the steel rolling system. In addition, the communication module has anti-interference function, and can automatically adjust the sending strategy when it finds that the signal is interfered, for example, increasing the number of repetitions to ensure that the information is successfully received. At the same time, the sending frequency can also be changed to adapt to the interference environment, thereby improving the reliability of data exchange.
[0043] The main rolling mill is equipped with a current sensor, which continuously monitors the pattern of current changes during each rolling process and compares it with the preset pass completion standard. When it is detected that the current reaches the preset standard, the rolling system automatically confirms that the pass has been completed and transmits the signal back to the control center to trigger the next rolling process.
[0044] The technical effect of the above content is: the current sensor of the main rolling mill can continuously monitor the pattern of current changes during each rolling process, and compare it with the preset pass completion standard. When it is detected that the current reaches the preset standard, the steel rolling system can automatically confirm that the pass has been completed and transmit the signal back to the control center to trigger the next rolling process. Among them, the current sensor of the main rolling mill can pre-set the current threshold. Once it is detected that the current exceeds 2.75 times the set threshold of the push bed, combined with the speed information, the steel rolling system will automatically determine whether a jam or equipment failure occurs, and issue an alarm or adjust the operation in time.
[0045] Specifically, this embodiment also proposes an implementation method of a steel rolling system based on automatic push-bed measurement and intelligent control, comprising the following steps:
[0046] When the rolling system is started, the front and rear positions and the pressing positions of the pusher will be automatically initialized to ensure that the mechanical parts are in the predetermined reference positions, and the position status of each mechanical component is confirmed by sensors to ensure the precise execution of subsequent operations;
[0047] When receiving the steel incoming signal, the rolling system determines whether the transmission side pusher needs to be directly positioned according to the pass table and the steel width range;
[0048] If direct positioning is required, the transmission side pusher will automatically move to the steel turning waiting position. At the same time, the rolling system automatically adjusts the roller gap according to the state of the steel, and the operating side pusher will slightly deviate from the target position to facilitate subsequent fine-tuning operations;
[0049] After the push bed clamps the steel, the rolling system calculates the precise width of the steel by measuring the current and torque of the push bed in the clamping state, and adjusts the final position of the push bed according to the data;
[0050] During the steel turning process, the operating side pusher retreats to the steel turning waiting position while clamping the steel. Then, the driving side pusher performs the steel turning operation, ensuring that the steel will not fall over or become unstable during the steel turning process by moving;
[0051] The rolling system continuously monitors the position of the pusher and the state of the steel during the rolling process to ensure the safety and stability of the entire process;
[0052] After the steel is turned, the rolling system determines which side pusher will perform the steel-beating operation according to the position of the transmission side pusher. At this time, the rolling system measures the width of the steel again and adjusts the positions of the transmission side pusher and the operating side pusher according to the latest data to ensure that the pusher is in the optimal operating position during the next rolling process.
[0053] After the main rolling mill, working roller table and frame roller table are started, the rolling system monitors the current status of the main rolling mill in real time during the rolling process. Through the current signal, the rolling system automatically determines whether the steel is successfully bitten into the main rolling mill and whether the current rolling pass is completed to ensure the timely completion of each pass.
[0054] Working principle: The present invention optimizes the rhythm of multiple operations, combines the positioning of the push bed, width measurement, steel turning judgment and rolling pass monitoring in a parallel task queue, so that each process is seamlessly connected. Through the real-time operating system, the synchronization and efficient execution of each process are ensured. By processing multiple steps in parallel, the traditional single-step processing method is merged, the pause time between operations is reduced, and the overall operating efficiency is significantly improved.
[0055] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
