Description

Technical Field

[0001] This invention relates to, in particular, a water propulsion device and its manufacturing method. Background Technology

[0002] In the production process of double high-speed wire rod mills, the loose coil transport roller conveyor plays a crucial role in stably transferring the loose coils formed after precision rolling to subsequent processes. The matching degree between its speed and the rolling line process and equipment operating status directly determines the continuity of production, the quality of finished products and the life of equipment. Therefore, precise matching of roller conveyor speed is one of the core requirements of high-speed wire rod production.

[0003] However, existing loose-roll conveyor control technology has significant shortcomings and defects, which have become a key bottleneck restricting production efficiency and cost control. The specific problems are as follows:

[0004] 1. The roller conveyor acceleration logic is not compatible with the equipment and process requirements, which can easily lead to equipment damage and production interruption.

[0005] In existing technologies, even after the tail steel acceleration function has been removed, the loose coil conveyor still triggers two unnecessary acceleration actions. This acceleration logic does not take into account the actual operating conditions of the on-site mechanical equipment, such as transmission load, component tolerance, and process control requirements, such as loose coil conveying rhythm and rolling line speed, resulting in a disconnect between the acceleration process and the equipment's load-bearing capacity and process requirements.

[0006] On the one hand, excessive acceleration can easily cause overload of the roller conveyor motor and excessive impact load on transmission components such as gears and bearings, leading to abnormal equipment damage. On the other hand, mismatch between acceleration and process can cause jamming or accumulation of loose coils during transport, forcing the production line to stop for processing, causing production interruption and affecting overall capacity.

[0007] 2. The acceleration mode is fixed and cannot be switched, resulting in poor quality control of finished products.

[0008] Existing roller conveyors only employ a single, fixed acceleration mode, lacking dynamic switching capabilities. In actual production, rolling line speeds, such as the finishing mill exit speed, and wire feeding parameters, such as the wire feeding frequency, are adjusted according to the workpiece specifications, such as diameter and steel grade characteristics. A fixed acceleration mode cannot dynamically match these process variations: for example, rolling small-diameter workpieces requires lower acceleration intensity to prevent scattering, while rolling large-diameter workpieces requires higher acceleration intensity to prevent accumulation. However, a single mode cannot accommodate both needs, leading to speed matching deviations. This crude control method can cause uneven scattering spacing, deformation, and other problems, thereby affecting the dimensional accuracy and mechanical properties of the finished product and reducing product quality stability.

[0009] 3. Fixed acceleration mode exacerbates equipment wear and tear, increasing production costs.

[0010] Due to the inability to switch the acceleration mode, components such as the chains and driving rollers of the roller table have been in a state of speed matching deviation for a long time. When the process requirements do not match the acceleration mode, the chains are prone to additional stretching or friction due to the speed difference, and the driving rollers are prone to local wear caused by uneven stress. Under long-term operation, the damage frequency of equipment components has increased significantly, and spare parts need to be frequently replaced. This not only increases the procurement cost of spare parts but also consumes additional working hours due to maintenance downtime, ultimately leading to a significant increase in the production cost per ton of steel.

[0011] 4. The lag in acceleration matching affects production efficiency and the long-term operation of equipment.

[0012] During the production process, rolling intervals, such as batch switching intervals and rolling stoppage intervals, such as equipment short-term maintenance intervals, will change dynamically according to the production plan. However, the fixed acceleration mode cannot quickly adapt to these interval changes, resulting in a serious lag in acceleration matching.

[0013] On the one hand, the lag will cause the scattered coils to be transported不畅 during the interval, affecting the connection of subsequent processes and reducing the overall production efficiency. On the other hand, the speed fluctuations caused by the lag will cause continuous impacts on the roller table and supporting equipment, shortening the service life of the equipment, making it difficult to ensure the long-term safe and stable operation of the equipment, and further increasing the risk of production interruption and operation and maintenance costs. Summary of the Invention

[0045] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can typically be arranged and configured in various different ways.

[0046] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0047] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0048] The following is in conjunction with the appendix Figures 1 to 2 The specific implementation methods of this application will be described in detail below.

[0049] This embodiment discloses a control method for intelligent combined diversified speed control of high-speed wire rod unwound conveyor rollers, such as... Figure 1 As shown, the steps are as follows:

[0050] The first step is to set up an acceleration control system for the head of the loose coil conveyor rollers. By accurately identifying the steel biting signal of the finishing mill and simultaneously setting up an upward trend acquisition system, triggering linkage can be achieved to realize the optimal control of the acceleration of the head of the loose coil conveyor rollers.

[0051] Furthermore, the basic control logic is as follows:

[0052] A Hall effect sensor (sensitivity 50mV / G) is used to monitor the finishing mill current in real time. When the current suddenly increases by ≥50% (i.e., reaches 150% of the steady-state current), a head acceleration control signal is triggered. The initial speed of the roller conveyor starts from 0.3m / s and increases at a slope of 0.15m / s. 2 Increase to the target speed (e.g., 0.65 m / s for Φ12mm rolled pieces), with a total acceleration time of 1.5 seconds; set the current signal sampling frequency to 1 kHz to ensure that the trigger response delay is <0.3 seconds, thus avoiding head roll accumulation.

[0053] Preferably, the steel bite signal identification in the precision rolling mill is achieved by combining a current transformer (0-5A input) and a torque sensor (±1% accuracy) and using a dual-condition judgment of "current sudden change + torque increase" to eliminate interference signals such as power grid harmonics.

[0054] Rising trend acquisition system: The sliding window differential algorithm (window width 100ms) is used to extract the rising edge features of the current signal. The steel biting signal is confirmed to be valid only when an upward trend is detected for 3 consecutive sampling periods, with a false trigger rate of <0.1%.

[0055] The second step is to set up an acceleration control system at the tail of the loose coil conveyor rollers. By accurately identifying the steel throwing signal of the finishing mill and simultaneously setting up a downward trend acquisition system, the system can trigger linkage and achieve optimal control of the acceleration at the tail of the loose coil conveyor rollers.

[0056] Furthermore, the basic control logic is as follows:

[0057] The finishing mill's steel ejection signal is jointly triggered by an infrared photoelectric switch (detection distance 0-50mm) and an encoder (1024PPR) at the last stand of the mill: when the end of the rolled piece leaves the last stand, the photoelectric switch outputs a falling edge pulse signal (pulse width 10ms), synchronously triggering tail acceleration. The roller conveyor speed decreases from 0.7m / s to -0.1m / s. 2 The slope is reduced to 0.4m / s, and the deceleration process covers a 15m roller conveyor length; at the same time, the tail steel RFID tag writing is started to record information such as tail steel specifications and temperature, providing identification for subsequent independent control.

[0058] Preferably, the anti-interference processing of the steel throwing signal is based on first-order hysteresis filtering (time constant 0.2s) to process the speed signal fed back by the encoder, so as to avoid signal fluctuations caused by mechanical vibration.

[0059] Falling trend acquisition: Real-time monitoring of the falling edge of the speed signal. When the speed shows a continuous downward trend for 500ms and the photoelectric switch is unobstructed, the steel throwing signal is confirmed to be valid.

[0060] The third step is to set up a time interval dual-end precision quantitative control system. By setting time-triggered visual signals and interval duration import units on the rolling process control screen, personalized control and matching precision quantitative control of acceleration time can be achieved.

[0061] Furthermore, the basic control logic is as follows:

[0062] In the HMI interface of the 7-inch embedded touchscreen (60Hz refresh rate), set the default acceleration time interval: 3 seconds for the head acceleration and 5 seconds for the tail acceleration, with support for ±0.5 seconds fine adjustment.

[0063] The PLC monitors the acceleration time in real time using a timer (1ms resolution). If the timeout is exceeded (e.g., the head acceleration exceeds 3.5 seconds), it automatically switches to safety mode, locks the roller speed at 0.5m / s, and triggers an audible and visual alarm.

[0064] Preferably, time-triggered visualization: the interface displays an acceleration progress bar and a number input box, and supports engineers to save 10 sets of preset parameters (such as 2.8 seconds for Q235 steel head and 3.2 seconds for 45# steel head);

[0065] Time interval import: Receive process parameters (including steel grade code, target temperature, etc.) from the MES system via the PROFINET communication protocol, and automatically match the corresponding time interval without manual input.

[0066] The fourth step is to set up a visual selection mode switching control system. By adding mode interlock and mode connection condition connection units and setting the connection variables as visual selection components, the system can achieve rapid and intelligent switching between the two modes.

[0067] Furthermore, the basic control logic is as follows:

[0068] The HMI interface features four acceleration mode checkboxes: Normal Mode (speed range 0.3-0.7 m / s, suitable for most operating conditions), Fast Mode (speed increased by 20%, used for rapid transfer of small-diameter rolled pieces), Energy Saving Mode (speed reduced by 15%, reducing power consumption), and Tail Steel Mode (independent speed curve, suitable for tail steel transfer). The mode switching response time is <0.8 seconds, ensuring uninterrupted operation.

[0069] Preferably, mode interlocking is implemented: the "one-selection" logic is achieved through PLC interlocking relays (contact capacity 10A), ensuring that only one mode is active at a time, thus avoiding logic conflicts.

[0070] Variable binding: Based on the OPC UA protocol, the check status is bound to the PLC's DB block (address offset 0x20-0x23), and the check action is synchronized to the control program in real time without the need to restart the system.

[0071] The fifth step is to set up a main speed setting control system for the roller conveyor. This is achieved by adding a speed matching control unit between the loose coil conveyor roller and the end exit of the rolling line, and setting up a speed output and visualization import system.

[0072] Furthermore, the basic control logic is as follows:

[0073] Based on the feedback value of the laser Doppler velocimeter (±0.5% accuracy) at the rolling line exit, the reference speed of the roller conveyor is dynamically calculated according to the formula V_main = 0.9 × V_rolling_line + 0.1 (m / s). For example, when the rolling line exit speed is 0.6 m / s, the main speed of the roller conveyor is set to 0.64 m / s, and the matching error is controlled within ±0.03 m / s.

[0074] Preferably, cross-regional linkage: the IEEE 1588 precision time protocol is adopted to ensure that the synchronization error of the control cycle (10ms) between the rolling line and the roller conveyor is <1μs, thus avoiding speed calculation lag;

[0075] Visual monitoring: Displays the real-time curve of the main speed on the SCADA interface (sampling interval 200ms), and supports exporting historical data in CSV format for easy process analysis.

[0076] The sixth step is to set up a roller conveyor acceleration additional speed control system, which intelligently identifies and outputs the matching acceleration amplitude, and adds an additional speed intelligent import control unit at the combined control import end, thereby achieving the optimal control of speed integration.

[0077] Furthermore, the basic control logic is as follows:

[0078] The distance between the rolls is detected by a laser rangefinder, and the additional velocity is dynamically calculated according to the formula ΔV=0.05×(Sactual-STarget)(m / s) (STarget defaults to 1.0m, compatible with Φ10mm specifications). For example, when the actual distance is 1.2m, the additional velocity is +0.01m / s; the maximum superposition amplitude is limited to ±0.15m / s to avoid excessive velocity fluctuations.

[0079] Preferably, amplitude quantization is performed by fitting the "spread gap-addition velocity" relationship curve using the least squares method, with a correlation coefficient R. 2 ≥0.95, to ensure calculation accuracy;

[0080] Intelligent import: Receives optimized parameters output by the AI ​​model via Modbus TCP protocol (update cycle 1 second), automatically corrects the additional speed calculation formula, and adapts to the loose coil characteristics of different steel grades.

[0081] The seventh step is to set up a multi-segment fully matched roller speed control system. By combining and optimizing the speed settings and speed matching tests of each segment, and adding an intelligent import control unit for rolling line speed difference correction, the optimal control of the multi-segment fully matched roller speed can be achieved.

[0082] Furthermore, the basic control logic is as follows:

[0083] The 60m long roller conveyor is divided into 5 independent sections (10m each), and the speed of each section is set as follows: Section 1 (head) 0.65m / s, Sections 2-4 (middle) 0.55±0.05m / s, Section 5 (tail) 0.45m / s, with a speed difference of ≤0.1m / s between sections to avoid unwound coils accumulating at the section junctions.

[0084] Preferably, the difference correction is as follows: an incremental encoder (5000 lines) is used to detect the speed difference between adjacent sections, and a PID controller (Kp=0.8, Ki=0.2) is used to correct it in real time. When the speed difference exceeds the limit, the output of the adjacent sections is automatically adjusted.

[0085] Rolling line connection: When the rolling line speed changes by more than 5%, the speed of the entire section is adjusted synchronously. The adjustment range is distributed proportionally to each section to avoid sudden changes in local speed.

[0086] The eighth step is to set up an independent control system for the tail section roller conveyor of the wire drawing machine. By adding an independent section control unit and a multi-dimensional condition intelligent matching control unit, and superimposing control with the trigger signal, the rolling adaptability control of the tail section roller conveyor can be realized.

[0087] This embodiment discloses a control method for intelligent combined diversified speed control of a high-speed wire rod conveyor roller, and a control system for intelligent combined diversified speed control of a high-speed wire rod conveyor roller, such as... Figure 2As shown, it includes a roller conveyor head acceleration control system and a tail acceleration control system, a zone dual-end quantization and visualization selection mode switching system, a roller conveyor main speed setting and acceleration additional speed control system, a multi-segment matching speed control system, and a tail steel tail control system.

[0088] Furthermore, the basic control logic is as follows:

[0089] When the RFID reader identifies the tail steel tag, it triggers independent tail control: the roller speed drops to 0.3m / s, and the frequency of the fan below is increased by 5Hz (to compensate for insufficient cooling of the tail steel); this state continues until the tail steel leaves the end of the roller (detected by the end photoelectric switch), and then normal control is restored.

[0090] Preferred multi-dimensional condition matching: Combining rolling logs (steel grade, temperature history) with real-time data from three infrared temperature measurement points, the optimal speed curve is generated through a fuzzy algorithm, such as appropriately increasing the speed of low-temperature tail steel to reduce dwell time;

[0091] Redundant control: The tail control unit uses a redundant CPU (switching time <100ms) to avoid single point failures causing tail steel to lose control.

[0092] The aforementioned head and tail acceleration control systems are used to first establish a head acceleration control system for the loose coil transport rollers. This system accurately identifies the steel biting signal from the finishing mill and simultaneously sets up an upward trend acquisition system to trigger a linkage, thereby achieving optimal control of the head acceleration of the loose coil transport rollers. Then, a tail acceleration control system for the loose coil transport rollers is established. This system accurately identifies the steel throwing signal from the finishing mill and simultaneously sets up a downward trend acquisition system to trigger a linkage, thereby achieving optimal control of the tail acceleration of the loose coil transport rollers.

[0093] Real-time acquisition of key equipment parameters: chain tension (measured by strain gauges, range 0-5000N), roller conveyor motor current (±1% accuracy), bearing temperature (PT100, ±0.5℃); when parameters are abnormal (such as motor current exceeding the limit by 10% or bearing temperature exceeding 60℃), the trigger speed is reduced by 20% to reduce the equipment load.

[0094] Preferably, the status recognition adopts a dual judgment of "static threshold comparison + dynamic LSTM prediction". For example, if the LSTM model predicts that the current will exceed the limit after 5 seconds, the derating will be started in advance, with a false alarm rate of <0.1%.

[0095] Anomaly Handling: If an anomaly lasts for more than 30 seconds, the system will automatically shut down and notify the maintenance personnel via SMS. At the same time, the parameter logs for the 10 seconds prior to the failure will be saved for easy tracing.
