Description

Technical Field

[0001] This application relates to the technical field of strip steel, and particularly relates to a strip steel warping control method and related equipment. Background Art

[0002] At present, in the modern steel processing industry, with the booming development of the manufacturing industry and the increasingly fierce market competition, customers have increasingly strict requirements for the quality of steel products. Among them, the flatness accuracy, as one of the key indicators to measure the quality of strip steel, has received high attention from customers. At the same time, in order to improve production efficiency and reduce labor costs, the degree of automation of the production line shearing is also continuously deepening. The combined effect of these two factors has put extremely strict requirements on the warping degree of the incoming strip steel. The warping problem of strip steel, specifically manifested as the phenomenon of upward or downward warping, seems minor but actually has a significant impact on the production process. In an automated production line, the strip steel needs to pass smoothly through various equipment to complete threading and shearing operations. However, once the strip steel warps, it will directly interfere with the production line equipment. This interference will not only cause the obstruction of the automatic threading process, prolong the threading time, reduce production efficiency, but also may cause equipment failures, increase maintenance costs and downtime. For the shearing operation, it is difficult to ensure the shearing accuracy of the warped strip steel, and it is easy to have shearing deviations, which will further affect the dimensional accuracy and appearance quality of the product and reduce the product qualification rate.

[0003] However, the existing production lines generally lack effective warping detection equipment, which makes the monitoring of the strip steel warping problem in the production process in a "blind area". Due to the inability to obtain the warping information of the strip steel accurately and in real time, it is difficult for production personnel to effectively control the warping problem. Once the strip steel warping problem appears in batches, due to the lack of early warning and preventive measures, they can only respond passively, which not only increases production costs but also seriously affects the smooth execution of the production plan. Among various types of strip steel, high-strength steel has been widely used in various fields due to its excellent strength performance. However, high-strength steel will generate greater internal stress during the production process, which makes its warping phenomenon more significant compared with ordinary strip steel. Once the high-strength steel has a warping problem, due to its own characteristics, it is more difficult to correct and causes more serious damage to the strip steel quality. This not only leads to a decline in the use performance of the product but also may cause potential safety hazards in the subsequent processing and use processes, further affecting the enterprise's market reputation and economic benefits. At present, there is no appropriate method to solve the above problems. Therefore, it is necessary to propose a strip steel warping control method to solve at least some of the above problems.

[0041] Please refer to Figure 1 , which is a schematic flow chart of a strip warping control method provided by an embodiment of the present application, and specifically may include:

[0042] S110. Obtain a sample to be tested;

[0043] Exemplarily, in the large-scale strip production process, it is impossible to comprehensively detect every inch of the strip. Therefore, it is necessary to obtain a representative sample to be tested and perform warping detection on it to infer the quality status of the entire batch of strips.

[0044] S120. Perform warping detection on the sample to be tested to obtain a warping detection result;

[0045] Exemplarily, by performing warping detection on the sample to be tested, specific data and conditions of strip warping can be obtained, that is, the warping detection result. The warping detection result can intuitively reflect whether the strip is warped, the direction of warping (upward warping or downward warping), and the degree of warping, so as to intuitively monitor the strip quality.

[0046] S130. In the case where the warping detection result is greater than the warping release standard, optimize the torque value of the leveler to which the sample to be tested belongs to control the strip warping.

[0047] Exemplarily, when the warping detection result of the sample to be detected shows that its warping degree exceeds the standard value of the warping release standard, it indicates that there is a problem with the quality of the strip steel being produced currently, and measures need to be taken for adjustment. When the warping detection result exceeds the standard, by optimizing the torque value of the temper mill to which the sample to be detected belongs, the stress state of the strip steel during the tempering process can be changed to achieve the purpose of correcting warping. Table 1 shows the warping release standard.

[0048] Serial number End user Width Thickness Sampling requirement Warpage release standard 1 A 954 1.2 Take a 1-meter-long sample ≤5mm 2 B -- -- Take a 0.5-meter-long sample ≤6mm 3 C -- -- Take a sample about 0.5 meters long ≤10mm

[0049] Table 1

[0050] In summary, the strip steel warping control method proposed in the embodiments of the present application can timely detect whether there is a warping problem with the strip steel exceeding the warping release standard by obtaining the sample to be detected and performing warping detection. For the case where the warping exceeds the standard, optimizing the torque value of the temper mill to which the sample to be detected belongs can specifically adjust the stress state of the strip steel during the tempering process, effectively improve the warping situation of the strip steel, ensure that the finally produced strip steel meets the quality requirements, reduce the unqualified rate of products caused by warping problems, and improve the overall quality and market competitiveness of the products.

[0051] In some examples, the step of obtaining the sample to be measured includes:

[0052] Obtain a strip steel product;

[0053] Cut a sample piece of a preset length from the strip steel product to obtain the sample to be detected.

[0054] Exemplarily, for the strip steel product that needs to measure warping, a sample piece of a preset length should be cut from the strip steel product. Among them, the preset length is 0.5 meters. Such a length is convenient for subsequent operations on the horizontal platform and can more accurately reflect the warping characteristics of the strip steel.

[0055] In some examples, the step of performing warping detection on the sample to be detected to obtain a warping detection result includes:

[0056] Place the sample to be detected on a horizontal platform;

[0057] Measure the maximum gap between the sample to be detected and the horizontal platform based on a feeler gauge to obtain a warping detection result.

[0058] Exemplarily, place the sample to be detected on the horizontal platform and measure the maximum gap between the sample to be detected and the horizontal platform with a feeler gauge. This maximum gap value is the warping detection result and is used as the specific value for measuring the C-warp or L-warp of the strip steel. A feeler gauge is a measuring tool used to measure narrow gaps. By inserting feeler gauge pieces of different thicknesses between the strip steel and the platform, the feeler gauge piece with the largest thickness that can just be inserted is found, and its thickness is the measured gap value.

[0059] For the first coil of strip produced in each batch, warpage measurement must be carried out. During mass production, warpage is measured once every 4 mother coils. Such a frequency setting can ensure product quality monitoring while taking into account production efficiency, and timely detect possible warpage problems in mass production with a reasonable detection frequency. If abnormal warpage of the strip is observed on the horizontal platform, regardless of whether the specified number of mother coils for measurement is reached, it is necessary to measure the template in a timely manner so as to promptly grasp the abnormal situation and take corresponding measures to avoid the mass production of unqualified products. For other products, the measurement frequency is relatively low, and it is measured once every 8 mother coils.

[0060] When recording the warpage measurement results, it is stipulated that upward warpage is represented by a positive number and downward warpage is represented by a negative number. This unified representation method makes the data recording more standardized and clear, facilitating subsequent data sorting, analysis and comparison, and can intuitively reflect the warpage direction and degree of the strip, helping to quickly judge whether the product meets the quality standards and take corresponding treatment measures.

[0061] In some examples, the steps after measuring the maximum gap between the sample to be detected and the horizontal platform based on the feeler gauge include:

[0062] In the case where the maximum gap is greater than the range of the feeler gauge, measure the maximum gap between the sample to be detected and the horizontal platform based on the tape measure to obtain the warpage detection result.

[0063] Exemplarily, in the warpage detection of strip steel, a feeler gauge is usually used to measure the maximum gap between the sample to be detected and the horizontal platform, and this is used as an index to measure the warpage degree. The feeler gauge has a certain range, which consists of thin sheets of different thicknesses, and the maximum gap that can be measured is limited. When the maximum gap between the sample to be detected and the horizontal platform exceeds the maximum thickness value that the feeler gauge can measure (i.e., greater than the range of the feeler gauge), the feeler gauge cannot accurately measure this gap value. In this case, it is necessary to replace the measuring tool and select a tape measure for measurement. The tape measure is a length measuring tool, usually with a larger range, which can meet the need to measure a larger gap. It can measure a longer distance, making up for the limitation of the feeler gauge in measuring large gaps.

[0064] In some examples, the steps of optimizing the torque value of the skin pass mill to which the sample to be detected belongs in the case where the warpage detection result is greater than the warpage release standard include:

[0065] Adjust the wrinkle prevention roll parameters of the skin pass mill to which the sample to be detected belongs to obtain the first adjustment result;

[0066] Based on the first adjustment result, adjust the work roll diameter of the skin pass mill to obtain the second adjustment result;

[0067] Adjust the insertion amounts of the first leveling roll group and the second leveling roll group based on the second adjustment result and the preset requirements, so as to control the warping of the strip steel.

[0068] Exemplarily, slight waviness and warping of cold-rolled steel coils can be eliminated after continuous annealing, but warping defects occur in the strip steel after temper rolling. As the temper rolling force increases, the plastic elongation difference increases, and the upward warping degree increases. As the torque increases, the elongation difference between the upper and lower surfaces first decreases and then increases; by changing the direction and magnitude of the torque of the lower roll motor, a downward warping trend can be generated in the strip steel, and it can be improved by optimizing the torque value. The methods for changing the torque include rolling force adjustment, strip steel roughness, roll diameter, etc. The optimization method for the torque value of the temper mill to which the sample to be detected belongs is as follows:

[0069] Adjust the wrinkle-resistant roll parameters of the temper mill to which the sample to be detected belongs to obtain a first adjustment result. The wrinkle-resistant roll is an important component of the temper mill, and its main function is to prevent the strip steel from generating wrinkles during the temper rolling process. Adjust the roll diameter of the work roll of the temper mill based on the first adjustment result to obtain a second adjustment result. The work roll is the component that directly performs the temper rolling operation on the strip steel, and the roll diameter size will affect the distribution of the rolling force and the deformation of the strip steel. By changing the roll diameter of the work roll, its warping condition can be improved. Specifically: optimize the configuration of the roll diameter size of the work roll, so that there is a certain roll diameter difference between the upper work roll and the lower work roll of the temper mill. When the large roll is on the upper side and the small roll is on the lower side during rolling, the strip steel will warp upward or have an upward warping trend; when the large roll is on the lower side and the small roll is on the upper side during rolling, the strip steel will warp downward or have a downward warping trend. In actual production, the warping direction of the strip steel is upward, so the roll arrangement form with the small roll on the upper side and the large roll on the lower side can be used to control the occurrence of upward warping.

[0070] Adjust the insertion amounts of the first leveling roll group and the second leveling roll group based on the second adjustment result and the preset requirements, so as to control the warping of the strip steel. The preset requirements are the goals and standards for strip steel warping control set in advance, such as the allowable maximum warping degree range of the strip steel, etc. Combine this second adjustment result and the preset requirements for analysis, and then adjust the insertion amounts of the first leveling roll group and the second leveling roll group to obtain a first adjustment result.

[0071] In some examples, the step of adjusting the wrinkle-resistant roll parameters of the motor to which the sample to be detected belongs to obtain a first adjustment result includes:

[0072] Adjust the height values of the entry wrinkle-resistant roll and the exit wrinkle-resistant roll of the temper mill to which the sample to be detected belongs to obtain an initial adjustment result;

[0073] Based on the initial adjustment result, increase the wrap angle between the wrinkle-resistant roll and the sample to be detected to obtain a first adjustment result.

[0074] Exemplarily, the height values of the entry wrinkle-preventing roll and the exit wrinkle-preventing roll of the leveler to which the sample to be detected belongs are adjusted to obtain an initial adjustment result, increasing the contact area between the upper surface of the strip without drive and the roll, reducing the elongation difference between the upper and lower surfaces, and reducing or even avoiding the occurrence of warping defects. At the same time, the wrap angle of the wrinkle-preventing roll and the sample to be detected can be increased to obtain a first adjustment result, reducing strip vibration, preventing the strip from wrinkling and improving the measurement accuracy of the non-contact shape meter, and improving warping. However, due to the narrow area of the wrinkle-preventing roll region, there are also equipment such as a leveling fluid spray beam, a purging spray beam, and a shape meter, and the wrinkle-preventing roll cannot be increased infinitely, and the adjustment amount for warping is limited.

[0075] In some examples, the step of adjusting the insertion amounts of the first straightening roll group and the second straightening roll group based on the second adjustment result and preset requirements to control the warping of the strip includes:

[0076] When the second adjustment result is that the sample to be detected has an upward warp, based on preset requirements, increase the insertion depth of the second straightening roll group or decrease the insertion depth of the first straightening roll group to control the warping of the strip;

[0077] When the second adjustment result is that the sample to be detected has a downward warp, based on preset requirements, decrease the insertion depth of the second straightening roll group or increase the insertion depth of the first straightening roll group to control the warping of the strip.

[0078] Exemplarily, a tension leveling machine with two bends and two straightenings can effectively control the warping of the strip through the cooperation of different insertion amounts of two straightening roll groups. When the insertion amount of the first straightening roll group increases, the downward warp of the strip increases; when the insertion amount of the second straightening roll group increases, the downward warp of the strip decreases. According to the specific requirements of different users for the warping direction and height, the warping control of the finished strip is achieved through the combination of different set values of the insertion amounts of the first straightening roll group and the second straightening roll group. When rewinding and tension leveling, the initial set tension is 120 KN, the insertion amounts of the 1# and 2# bending rolls are 65 mm, and the insertion depths of the 1# and 2# straightening rolls are 32 mm. Adjust the insertion depths of the 1# and 2# straightening rolls according to the actual warping situation. When observing that the strip has an upward warp at the exit of the tension leveling machine, increase the insertion depth of the 2# straightening roll or decrease the insertion depth of the 1# straightening roll; when there is a downward warp, increase the insertion depth of the 1# straightening roll or decrease the insertion depth of the 2# straightening roll to ensure that the warping height of the finished strip meets the shape judgment standard.

[0079] The leveler is the last process for correcting the strip shape before the steel coil is finally used by the user. In a tension-free state, the strip is repeatedly bent and deformed by the leveling rolls. While eliminating the residual stress inside the strip, the warping of the strip is finally controlled to achieve the purpose that the warping height of the cut steel plate meets the requirements of subsequent processes. Increasing the insertion amount of the leveling rolls makes the lower surface of the strip extend more than the upper surface, causing the strip to warp upward. When the raw material has a downward warping defect, such a leveler has strong correction ability; but when the raw material has an upward warping, its improvement ability is weak. The upper and lower roll systems of the multi-roll leveler are integral structures, and the warping of the strip is controlled by adjusting the insertion amounts of the first leveling roll group and the second leveling roll group at the inlet and outlet. Different rolling forces, bending roll forces, and tensions are specified according to different specifications to essentially reduce the warping height.
