[0001] The present application relates to the field of metallurgical technology, and in particular to a method for controlling the inner ring of a steel coil to prevent a single-sided tower-shaped overflow and rollover and related equipment. Background Art

[0002] Occasionally, a single-sided tower-shaped overflow may occur when the pickling mill is unwinding. If the overflow on the driving side is serious, it is very easy to hang on the mandrel of the coiler, causing the coiler to flip over directly when rotating, and causing the lateral distance on both sides to be long. The stepping beam crane clamp cannot close the coil, resulting in prolonged downtime.

[0003] Therefore, it is necessary to propose a single-sided tower-shaped overflow and anti-rolling control method for the inner ring of a steel coil to solve the above problems. Summary of the invention

[0004] A series of simplified concepts are introduced in the Summary of the Invention section, which will be further described in detail in the Detailed Description of the Invention section.

[0014] In a feasible implementation manner, monitoring and adjusting the working parameters of the pinch roller based on the pinch roller data includes:

[0015] The current pinch roller pressure is adjusted by the pinch roller data to change the pinch roller's clamping force on the material according to different production goals and material properties;

[0016] The control system analyzes the pinch roller data to obtain a target adjustment height, and adjusts the roller gap heights on both sides of the pinch roller according to the target adjustment height.

[0017] In a feasible implementation manner, judging the current state of the steel coil based on the steel coil data so as to stop the sequential control operation when the steel coil overflows in a tower shape includes:

[0018] Based on the steel coil data, obtaining the centerline width of the steel coil;

[0019] According to the centerline width of the steel coil and the travel distance of the trolley, it is determined whether the current steel coil has a tower-shaped overflow;

[0020] If a tower overflow occurs, the current sequential control operation will be stopped.

[0021] In a feasible implementation manner, judging whether the current steel coil has a tower-shaped overflow according to the width of the center line of the steel coil and the distance traveled by the trolley includes:

[0022] Obtaining the ratio of the centerline width of the steel coil to the travel distance of the trolley;

[0023] If the ratio exceeds a preset threshold, it is determined that the current steel coil has a tower-shaped overflow;

[0024] If the ratio does not exceed the preset threshold, it is determined that the current steel coil does not have a tower-shaped overflow situation.

[0025] In a feasible implementation manner, after the mandrel is retracted, the position and transport state of the trolley are adjusted.

[0026] In a feasible implementation, during the coiling stage, the tension of the coiling aid is increased according to a preset value so that the inner ring of the steel coil is wound tightly.

[0027] In a second aspect, the present application proposes a steel coil inner ring single-sided tower-shaped overflow anti-rolling control device, which is applied to the steel coil inner ring single-sided tower-shaped overflow anti-rolling control method described in any one of the above embodiments, comprising:

[0042] The present application provides a method for preventing rollover from occurring when a steel coil inner ring has a single-sided tower-shaped overflow. By analyzing the causes of the inner ring tower formation and the changing points of the unwinding process, the inner ring tower formation can be solved and rollover accidents can be avoided.

[0043] See also Figure 1, which is a schematic diagram of the process of a method for controlling the inner ring of a steel coil to prevent the inner ring from overturning and overflowing on one side of a tower shape provided in an embodiment of the present application, and may specifically include:

[0044] S110, collecting target data during the coiling process of the pickling mill in real time; the target data includes pinch roll data and steel coil data.

[0045] In some examples, real-time acquisition of target data during the unwinding process of the pickling mill includes:

[0046] The pinch roller data is collected in real time by sensors, wherein the sensors are arranged on bearing seats at both ends of the pinch roller;

[0047] The steel coil data is collected in real time by a grating detection device, wherein the grating detection device is arranged on the lower coil offline outside the core shaft.

[0048] For example, a sensor is installed at the pinch roller to better monitor the working status of the pinch roller, so as to obtain the pinch roller data for subsequent adjustment and control. A pair of grating detection devices are installed on the lower coil line outside the mandrel, and the position and status of the steel coil can be monitored in real time through grating detection.

[0049] S120, monitoring and adjusting the working parameters of the pinch roller based on the pinch roller data; the working parameters include the pinch roller pressure and the roller gap height on both sides of the pinch roller.

[0050] For example, the pinch roller pressure can be adjusted by the pinch roller data fed back by the sensor, and the roller gap height on both sides of the pinch roller can be further adjusted so that the pinch roller can adapt to materials of different thicknesses.

[0051] S130, obtaining a preset lifting height of the trolley, and storing the preset lifting height, so as to control the trolley to transport the steel coil to a target position based on the preset lifting height after the steel coil reaches a target size.

[0052] Exemplarily, the trolley is used to move to the bottom of the coiler after the strip is coiled on the coiler to form a steel coil, ready to receive and transport the steel coil. It has the function of memorizing the preset lifting height (i.e. storing the preset lifting height), and can perform secondary high-speed slight adjustments after the mandrel is retracted. The mandrel is used to coil the steel coil and can be retracted. The trolley can remember the preset lifting height when performing lifting and transportation operations. In this way, the steel coil can be accurately lifted from the coiler and transported to the designated location. This can improve the accuracy and efficiency of the operation and avoid the need to reset the lifting height every time.

[0053] S140. Determine the current state of the steel coil based on the steel coil data, so as to stop the sequential control operation when the steel coil overflows in a tower shape.

[0054] For example, when a steel coil is detected to overflow in a tower shape, stopping the sequential control operation means immediately interrupting the ongoing operation process that is automatically executed in a predetermined order. This is done to prevent the abnormal situation from further expanding, avoid causing greater damage to the equipment, and reduce the deterioration of product quality problems. It also provides operators with time to deal with the abnormal situation so that they can restart the normal sequential control process to continue production after the problem is solved.

[0055] In some examples, monitoring and adjusting operating parameters of the pinch roller based on the pinch roller data includes:

[0056] The current pinch roller pressure is adjusted by the pinch roller data to change the pinch roller's clamping force on the material according to different production goals and material properties;

[0057] The control system analyzes the pinch roller data to obtain a target adjustment height, and adjusts the roller gap heights on both sides of the pinch roller according to the target adjustment height.

[0058] For example, the pressure of the pinch roller can be adjusted through the pinch roller data fed back by the sensor. In this way, the pinch roller's clamping force on the material can be flexibly changed according to different production requirements and material properties to ensure the stability of the material during the conveying process.

[0059] Furthermore, position sensors or pressure sensors are installed at the pinch rollers. The sensors monitor parameters such as the roller gap height or the pressure of the pinch rollers on the steel coils in real time, and feed these data back to the control system. The control system calculates the target adjustment height through an algorithm based on the preset target value and the data fed back by the sensor, and then issues instructions to control the mechanical adjustment mechanism (such as a hydraulic system or an electric actuator) to adjust the roller gap height. This method can achieve automatic and precise adjustment to adapt to different production conditions and steel coil specifications. By adjusting the roller gap height on both sides of the pinch rollers, the pinch rollers can adapt to materials of different thicknesses. At the same time, the human intervention means that the operator can adjust and control these functions according to the actual situation, which improves the flexibility and controllability of the production process.

[0060] In some examples, judging the current state of the steel coil based on the steel coil data so as to stop the sequential control operation when the steel coil overflows in a tower shape includes:

[0061] Based on the steel coil data, obtaining the centerline width of the steel coil;

[0062] According to the centerline width of the steel coil and the travel distance of the trolley, it is determined whether the current steel coil has a tower-shaped overflow;

[0063] If a tower overflow occurs, the current sequential control operation will be stopped.

[0064] For example, a sensor is installed on the track of the steel coil trolley to monitor the distance the trolley travels in real time. When the trolley moves from the initial position to the position to receive the steel coil, the distance the trolley travels is recorded. The sensor is calibrated regularly to ensure the accuracy of the measurement. An object of standard length can be used to measure on the track and compared with the sensor reading. If there is any deviation, it can be adjusted in time.

[0065] Furthermore, by comparing the centerline width of the steel coil and the travel distance of the trolley, it can be determined whether the steel coil has a tower-shaped overflow. If the tower-shaped overflow of the steel coil exceeds the allowable range, corresponding measures need to be taken. When a tower-shaped overflow of the steel coil is detected, the sequential control operation is stopped. This can prevent the tower problem from further deteriorating, and at the same time protect the safety of equipment and personnel.

[0066] In some examples, judging whether the current steel coil has a tower-shaped overflow situation based on the width of the center line of the steel coil and the distance traveled by the trolley includes:

[0067] Obtaining the ratio of the centerline width of the steel coil to the travel distance of the trolley;

[0068] If the ratio exceeds a preset threshold, it is determined that the current steel coil has a tower-shaped overflow;

[0069] If the ratio does not exceed the preset threshold, it is determined that the current steel coil does not have a tower-shaped overflow situation.

[0070] Exemplarily, when there is no tower overflow of the steel coil, the centerline width of the steel coil should correspond to the travel distance of the trolley. For example, if the standard width of the steel coil is W, and the distance from the initial position of the trolley to the receiving steel coil is L, under normal circumstances, when the steel coil is well coiled, there is a certain proportional relationship between W and L, which can be obtained through actual measurement and calculation. When the steel coil has a tower overflow, the actual width of the steel coil will exceed the standard width in some parts. At this time, if the centerline width W1 of the steel coil is measured, it will be found that W1 is greater than W in normal circumstances. At the same time, since the tower overflow part will affect the receiving position of the trolley, the travel distance L1 of the trolley at this time will be different from L in normal circumstances. According to actual production experience and measurement data, a preset threshold is set. When the ratio of the centerline width of the steel coil to the travel distance of the trolley exceeds this preset threshold, it can be judged that the steel coil has a tower overflow. For example, if the ratio of W / L is K under normal circumstances, a threshold range is set, such as K±ΔK. When the ratio of W1 / L1 actually measured exceeds this range, it is judged as a tower overflow.

[0071] In some examples, this also includes:

[0072] After the mandrel is retracted, the position and transport state of the trolley are adjusted.

[0073] For example, after the mandrel is retracted, the trolley performs a secondary high-speed slight adjustment to further optimize the position and state of the trolley and ensure the stability and accuracy of the steel coil during transportation and unwinding.

[0074] Specifically, the preset lifting height stored in the trolley allows the trolley to accurately remember the appropriate height required to lift the steel coil from the coiler. When the steel coil is being coiled, if the tower problem occurs, it is usually because the tension on both sides of the strip is uneven or the position is offset when the strip is coiled. The trolley can receive the steel coil at a precise height, so that it can be smoothly removed from the coiler as soon as the steel coil is formed, avoiding the tower problem caused by the steel coil staying on the coiler for too long, which will further aggravate the tower problem. With the stored preset lifting height, the trolley can provide stable support for the steel coil in the appropriate position. This helps prevent the steel coil from shaking or tilting during the lifting process, thereby reducing the misalignment between the strip layers caused by instability, and thus reducing the occurrence of towers.

[0075] Furthermore, since the trolley remembers the accurate preset lifting height, after receiving the coiling signal, it can quickly and accurately move to the bottom of the coiler and lift it to the appropriate position to receive the coil, without repeated attempts to adjust the height, which greatly saves time and improves the speed and efficiency of coiling. At the same time, it can also make the cooperation between the trolley and the coiler more tacit. Once the coil reaches the predetermined size, the trolley can immediately receive it at the optimal height and position, realizing a seamless connection from coiling to coiling, making the whole process smoother, reducing production pauses caused by waiting for the trolley to adjust its position, and improving the overall operating efficiency of the unit.

[0076] In some examples, this also includes:

[0077] During the coiling stage, the tension of the coiler is increased according to the preset value to tighten the inner ring of the steel coil.

[0078] For example, the tension of the coiling aid is increased by 15% according to the preset value, so that the inner ring of the steel coil is wound more tightly together. Specifically, increasing the tension by 15% can ensure that the inner ring is tightly wound without affecting the quality and production efficiency of the steel coil. Tightening the inner ring can reduce the looseness and deformation of the steel coil, improve the quality and stability of the steel coil, and also help reduce the occurrence of the tower problem.

[0079] In summary, the present application provides a method for preventing the inner ring of a steel coil from overturning due to a one-sided tower-shaped overflow. By adding a sensor at the clamping roller, the pressure adjustment and the height adjustment functions of the roller gaps on both sides are added to achieve personnel intervention. The function of the trolley memory lifting height is added, and the trolley is slightly adjusted at high speed for the second time after the core shaft shrinks. A pair of grating detections are added to the unwinding line on the outside of the core shaft. Based on the comparison between the centerline width of the steel coil and the travel distance of the trolley, the sequential control is stopped when the tower overflows. Increase the tension of the auxiliary coiler by 15% to ensure that the inner ring is tightly wound. While substantially reducing the tower-shaped problem, the unwinding smoothness of the unit is improved.

[0080] The technical solution of the present application is further described in detail below through specific embodiments.

[0081] Step 1. Install sensors at the pinch rollers: The pinch rollers will be engaged before and after shearing of the rolling mill to keep the tension stable. However, the pinch rollers on both sides are horizontal, and the pressure forms a wedge-shaped roll gap due to wear, which will cause the positions of both sides to shift when the strip head enters the mandrel and the rolls to be uneven. By adding sensors at the pinch rollers, the interface adds pressure adjustment and roll gap height adjustment functions on both sides. When the operating side is in a tower shape, the operating side can be intervened to adjust the pressure, and vice versa, the driving side can be adjusted to achieve personnel intervention.

[0082] Step 2: Store and adjust the preset lifting height of the trolley for the second time: For wide and thick automotive sheet materials weighing more than 35 tons, after the mandrel shrinks, the gravity of the large roll instantly acts on the unwinding trolley, resulting in a settlement of about 3mm, causing the center line of the lower roll to lower, and causing it to scrape against the mandrel and overflow. The preset lifting height of the trolley is stored, and after the mandrel shrinks, the trolley is slightly adjusted for the second time at high speed. The lifting height must be a positive or negative deviation of 0.5mm before the mandrel shrinks before the roll can be unwound.

[0083] Step 3: Add a pair of grating detection devices on the outer side of the mandrel before rolling off: If the unilateral overflow on the driving side is not discovered in time, it will cause a vicious accident of rolling when the mandrel rotates. Therefore, targeted learning is carried out, and the rolling control mode of a mature example is selected as a reference benchmark. The specific measures are to add a pair of grating detection devices on both sides of the rolling route outside the mandrel. According to the comparison of the centerline width of the steel coil and the travel distance of the trolley, when the tower shape of the rolling is serious, the overflow edge will block the signal, and the rolling will be stopped at this time to prevent the occurrence of vicious accidents.

[0084] Step 4: Increase the tension and effect of the coiler: When producing strip steel with a thickness of 2.0 mm or more, it is difficult for the strip steel to bend and deform, and it is difficult for the strip steel to hold the mandrel tightly. By increasing the opening of the servo valve, the tension of the coiler can be increased by 15% to ensure that the inner ring is rolled tightly.

[0085] In summary, through the above implementation steps, the production line slowdown and shutdown caused by unilateral tower overflow can be reduced by about 1 hour per month, with an average hourly output of 350 tons. According to the production impact of 120 yuan / ton manufacturing fee, the increase in production and the increase in benefits are 42,000 yuan / month. The cost of tower processing for deduplication coil processing is reduced by 300 yuan / roll per month, with a processing volume of about 200 rolls, and the reprocessing cost is reduced by 60,000 yuan / month. Total annual benefits = (4.2+6)×12 months = 1.224 million / year.

[0086] It should be noted that the above embodiments are only the best examples and are not limitations on the implementation methods of the present application.

[0087] Furthermore, the present application also proposes a steel coil inner ring single-sided tower-shaped overflow anti-rolling control device, which is applied to any of the above-mentioned steel coil inner ring single-sided tower-shaped overflow anti-rolling control methods, specifically as follows Figure 2 As shown, it is a functional module schematic diagram of a steel coil inner ring single-side tower-shaped overflow anti-rolling control device proposed in this application, including:

[0091] The unit operation control module 24 is used to determine the current state of the steel coil based on the steel coil data, so as to stop the sequential control operation when the steel coil overflows in a tower shape.
