Description

Technical Field

[0001] This invention relates to the field of production environment monitoring technology, and in particular to a quality control system and method for magnesium oxide coating on silicon steel surfaces based on data analysis. Background Technology

[0002] To further improve the performance of silicon steel, coating its surface with magnesium oxide is a widely used process. Magnesium oxide coating plays several important roles. It forms an insulating film on the silicon steel surface, effectively reducing eddy current losses between silicon steel sheets and improving the electrical insulation performance of the silicon steel. Simultaneously, the magnesium oxide coating prevents rust and corrosion on the silicon steel surface, extending its service life. Furthermore, during high-temperature annealing, the magnesium oxide coating acts as a release agent, preventing the silicon steel sheets from sticking together and ensuring the flatness and surface quality of the silicon steel sheets. However, controlling the quality of magnesium oxide coating on silicon steel surfaces still faces many challenges. Existing coating quality control methods often focus on single factors, lacking comprehensive analysis of multiple factors such as the surface condition of silicon steel, the usage environment, and the coating process. For example, when determining the thickness of magnesium oxide coating, traditional methods usually rely solely on empirical formulas or simple experimental data, without fully considering the differences in the microstructure of the silicon steel surface and the influence of environmental factors during the coating process. This single-factor control method easily leads to inaccurate coating thickness, thus affecting the performance of silicon steel. In terms of predicting magnesium oxide adhesion, existing technologies often only focus on the roughness of the silicon steel surface, ignoring the matching relationship between the shape and size of magnesium oxide particles and the pits on the silicon steel surface, as well as the influence of environmental factors on the adhesion effect. This makes the magnesium oxide coating weakly adhered during the actual coating process, prone to peeling, and reducing the protective performance of silicon steel. In addition, existing coating effect analysis methods mainly focus on static evaluation, without fully considering the impact of friction and collision on the coating during actual use. Silicon steel is inevitably subjected to friction and collision during transportation, installation, and use, which may damage the coating and affect the performance and service life of silicon steel. Existing coating effect analysis methods cannot accurately assess this dynamic risk and are unable to provide effective quality control measures. Summary of the Invention

[0003] In order to overcome the defects and shortcomings of the existing technology, the present invention provides a quality control system and method for magnesium oxide coating on silicon steel surface based on data analysis.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a method for quality control of magnesium oxide coating on silicon steel surfaces based on data analysis, comprising the following steps: Step S1: Obtain the surface condition of silicon steel and usage data, the environmental conditions of magnesium oxide coating and the corresponding magnesium oxide coating conditions; Step S2: Predict the coating condition based on the surface condition of silicon steel and the corresponding magnesium oxide coating condition, and predict the magnesium oxide adhesion based on the coating condition prediction results and the magnesium oxide coating environment. Step S3: Analyze the effect of magnesium oxide coating based on the magnesium oxide adhesion prediction results and the usage data of silicon steel during use; Step S4: Analyze the coating thickness on the silicon steel surface based on the results of the magnesium oxide coating effect analysis; Step S5: Apply magnesium oxide to the silicon steel surface according to the corresponding coating thickness.

[0005] In one implementation of the present invention, the silicon steel surface condition includes a three-dimensional image of the silicon steel surface, acquired by a laser profilometer; the silicon steel usage data includes the force and number of frictions and collisions during the use of the silicon steel, acquired by corresponding silicon steel usage records; the magnesium oxide coating environment condition includes environmental data affecting the coating quality, such as temperature and humidity, acquired by environmental sensors; and the corresponding magnesium oxide coating condition includes the shape, uniformity, and adhesion strength of the coating particles, acquired by obtaining corresponding data through magnesium oxide coating experiments, where the shape refers to the three-dimensional shape of the magnesium oxide particles and the uniformity refers to the uniformity of the particle size of the magnesium oxide particles.

[0006] In one implementation of the present invention, the abnormal prediction of magnesium oxide adhesion in step S2 includes the following specific steps: S21. Obtain the three-dimensional image data of the corresponding silicon steel surface, including the shape and size of the pits on the silicon steel surface, and the shape and size of the magnesium oxide particles. The size here is preferably the volume of the particles and the pits. By accurately measuring the volume of the pits and magnesium oxide particles on the silicon steel surface using three-dimensional imaging technology (such as laser scanning or optical profilometer), the microstructure of the coated substrate can be characterized more intuitively, rather than relying solely on the two-dimensional projection size. The volume data can better reflect the actual coating contact area, improving the accuracy of subsequent matching analysis. The coating quality is directly related to the degree of filling of the magnesium oxide particles in the pits, and the filling effect is determined by the matching of the shape and volume of the particles and the pits. Therefore, obtaining three-dimensional data is more valuable than traditional two-dimensional measurement. S22. The shape matching degree is analyzed by the shape of the pits on the silicon steel surface and the shape of the magnesium oxide particles. At the same time, the matching uniformity analysis is performed by averaging the uniformity of the size of the pits on the silicon steel surface and the uniformity of the size of the magnesium oxide particles. The coating uniformity prediction analysis result is obtained by weighted summing the shape matching degree analysis result and the matching uniformity analysis result. The uniformity of pit size and magnesium oxide particle size can be calculated using the standard deviation formula. Then, the uniformity of the corresponding data can be obtained by subtracting the standard deviation calculated by the corresponding standard deviation formula from 1. The standard deviation reflects the dispersion of the data, and 1-standard deviation can be converted into a uniformity index. Meanwhile, the method for analyzing the degree of shape matching is as follows: obtain the shape of the standard pit and the shape of the corresponding standard magnesium oxide particle, and obtain the degree of shape matching by dividing the volume of the intersection of the two shapes by the volume of the union of the two shapes. This can quantitatively assess the geometric compatibility between magnesium oxide particles and pits, avoiding reliance on experience alone. Furthermore, the weights for the weighted summation here are obtained through experiments using historical data. S23. Obtain environmental data affecting coating quality during the coating process. Set the standard deviation of each environmental data point from the corresponding safe range of the environmental data as the outlier of the corresponding environmental data. Sum the outliers of all types of environmental data by weight to obtain the environmental outlier. It should be noted that the standard deviation here is the difference between the environmental data and the median of the safe range divided by the difference of the safe range. The weighting weights are obtained through experiments. Obtain the impact of each environmental change on the coating quality. Allow for flexible adjustment of the sensitivity to environmental fluctuations. S24. Multiply the obtained environmental anomaly value by the environmental impact coefficient to obtain the environmental impact result. Multiply the difference between 1 and the environmental impact result by the coating uniformity prediction analysis result to obtain the magnesium oxide adhesion prediction result.

[0007] In one implementation of the present invention, the analysis of the magnesium oxide coating effect in step S3 includes the following specific contents: S31. Obtain the average force and frequency of friction and collision during the historical use of the corresponding silicon steel, as well as the adhesion force after the corresponding magnesium oxide coating is bonded. Obtain the detachment force anomaly by dividing the average force of friction and collision during the historical use of the corresponding silicon steel by the adhesion force after the corresponding magnesium oxide coating is bonded. Obtain the detachment frequency anomaly by the ratio of the frequency of friction and collision during use to the safe frequency. Obtain the adhesion detachment anomaly by multiplying the detachment force anomaly by the detachment frequency anomaly. The adhesion detachment anomaly assesses its dynamic risk by quantifying the degree of damage to the coating by external force. S32. Obtain the reciprocal of the adhesion detachment anomaly to get the adhesion fixation coefficient. To avoid the denominator being 0 and the reciprocal being meaningless, a very small constant needs to be added to the denominator. The adhesion fixation coefficient and the magnesium oxide adhesion prediction result are weighted and summed to obtain the magnesium oxide coating effect.

[0008] In one implementation of the present invention, the analysis of coating thickness in step S4 includes the following specific details: S41. Obtain the magnesium oxide coating effect threshold and the coating thickness corresponding to the threshold, and at the same time obtain the magnesium oxide coating effect obtained from the analysis. S42. The required magnesium oxide coating thickness for silicon steel is obtained by multiplying the ratio obtained by dividing the magnesium oxide coating effect threshold by the corresponding magnesium oxide coating effect and then multiplying the ratio by the coating thickness corresponding to the threshold. In industrial production, the qualified standard for magnesium oxide coating effect is usually determined by experiments or industry specifications. For example, the coating effect of a certain silicon steel product must reach the threshold to be considered qualified, and the corresponding ideal coating thickness is 5μm±0.5μm. If the actual test finds that the coating effect does not meet the standard, the process can be adjusted by calculating the compensation thickness: First, divide the threshold by the actual effect to obtain the compensation coefficient, and then multiply this coefficient by the standard thickness to determine the new target coating thickness. This method can not only accurately repair defective batches, but also optimize the production process.

[0009] In one implementation of the present invention, step S5, which involves coating the silicon steel surface with magnesium oxide according to the corresponding coating thickness, includes the following specific details: The required magnesium oxide coating thickness for the corresponding silicon steel is compared with the safe range of the actual coating thickness used. If the required magnesium oxide coating thickness for the corresponding silicon steel is within the safe range of the actual coating thickness used, then the coating is performed according to the required magnesium oxide coating thickness for the corresponding silicon steel. If the required magnesium oxide coating thickness for the corresponding silicon steel is not within the safe range of the actual coating thickness used, then a message is displayed indicating that coating cannot be performed, and the silicon steel or magnesium oxide coating needs to be replaced. The safe range of the actual coating thickness used here is obtained according to the actual scenario or according to the safe coating thickness of the coating equipment. The advantage of this comparison method is that it ensures that the magnesium oxide coating meets the process requirements.

[0010] Secondly, the present invention also provides a data analysis-based quality control system for magnesium oxide coating on silicon steel surfaces, comprising: The data acquisition module acquires information on the surface condition of silicon steel, usage data, the environmental conditions of magnesium oxide coating, and the corresponding magnesium oxide coating condition. The magnesium oxide adhesion prediction module predicts the coating condition based on the surface condition of silicon steel and the corresponding magnesium oxide coating condition, and then predicts the magnesium oxide adhesion based on the coating condition prediction results and the magnesium oxide coating environment. The coating effect analysis module analyzes the effect of magnesium oxide coating by using the magnesium oxide adhesion prediction results and the usage data of silicon steel during the application process. The coating thickness analysis module analyzes the coating thickness on the silicon steel surface based on the results of the magnesium oxide coating effect analysis. The coating determination module coats the silicon steel surface with magnesium oxide according to the corresponding coating thickness of the silicon steel surface.

[0011] Thirdly, the present invention provides an electronic device comprising: a processor and a memory, wherein the memory stores a computer program that can be called by the processor, and the processor executes a data analysis-based method for quality control of magnesium oxide coating on silicon steel surfaces by calling the computer program stored in the memory.

[0012] Fourthly, the present invention provides a computer-readable storage medium storing instructions that, when executed on a computer, cause the computer to perform a data analysis-based method for quality control of magnesium oxide coating on silicon steel surfaces.

[0013] Compared with the prior art, the present invention has the following advantages and beneficial effects: The solution comprehensively acquires data on the silicon steel surface, usage, coating environment, and coating itself. Through steps such as coating condition prediction, magnesium oxide adhesion prediction, coating effect analysis, and coating thickness analysis, it accurately determines the magnesium oxide coating thickness on the silicon steel surface. In magnesium oxide adhesion prediction, it comprehensively considers the shape and size matching of pits on the silicon steel surface and magnesium oxide particles, as well as environmental factors, to avoid prediction deviations caused by a single factor. The coating effect analysis combines the historical friction and collision data of the silicon steel and the coating adhesion to assess dynamic risks. The coating thickness analysis accurately calculates the required coating thickness based on the coating effect threshold. Finally, the required coating thickness is compared with the safe range to ensure that the coating meets both process requirements and actual operating conditions, mitigating production risks from the source and ensuring product quality and process feasibility.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0018] Example 1 like Figures 1 to 2 As shown, this embodiment provides a data analysis-based method for quality control of magnesium oxide coating on silicon steel surfaces, specifically including the following steps: Step S1: Obtain the surface condition of silicon steel and usage data, the environmental conditions of magnesium oxide coating and the corresponding magnesium oxide coating conditions; In this embodiment, it should be noted that the silicon steel surface condition includes a three-dimensional image of the silicon steel surface, obtained through a laser profilometer; the silicon steel usage data includes the force and number of friction and collisions during the silicon steel usage process, obtained through corresponding silicon steel usage records; the magnesium oxide coating environment condition includes environmental data affecting coating quality, such as temperature and humidity, obtained through environmental sensors; and the corresponding magnesium oxide coating condition includes the shape and uniformity of the coating particles, as well as the adhesion after bonding, obtained through corresponding magnesium oxide coating experiments. The shape refers to the three-dimensional shape of the magnesium oxide particles, and the uniformity refers to the uniformity of the particle size. All data in this embodiment are stored in corresponding storage components. Step S2: Predict the coating condition based on the surface condition of silicon steel and the corresponding magnesium oxide coating condition, and predict the magnesium oxide adhesion based on the coating condition prediction results and the magnesium oxide coating environment. In this embodiment, it should be noted that the abnormal prediction of magnesium oxide adhesion in step S2 includes the following specific steps: S21. Obtain the three-dimensional image data of the corresponding silicon steel surface, including the shape and size of the pits on the silicon steel surface, and the shape and size of the magnesium oxide particles. The size here is preferably the volume of the particles and the pits. By accurately measuring the volume of the pits and magnesium oxide particles on the silicon steel surface using three-dimensional imaging technology (such as laser scanning or optical profilometer), the microstructure of the coated substrate can be characterized more intuitively, rather than relying solely on the two-dimensional projection size. The volume data can better reflect the actual coating contact area, improving the accuracy of subsequent matching analysis. The coating quality is directly related to the degree of filling of the magnesium oxide particles in the pits, and the filling effect is determined by the matching of the shape and volume of the particles and the pits. Therefore, obtaining three-dimensional data is more valuable than traditional two-dimensional measurement. S22, such as Figure 4 As shown, the shape matching degree is analyzed by the shape of the pits on the silicon steel surface and the shape of the magnesium oxide particles. At the same time, the matching uniformity analysis is performed by averaging the uniformity of the size of the pits on the silicon steel surface and the uniformity of the size of the magnesium oxide particles. The coating uniformity prediction analysis result is obtained by weighted summing the shape matching degree analysis result and the matching uniformity analysis result. The uniformity of pit size and magnesium oxide particle size can be calculated using the standard deviation formula. Then, the uniformity of the corresponding data can be obtained by subtracting the standard deviation calculated by the corresponding standard deviation formula from 1. The standard deviation reflects the dispersion of the data, and 1-standard deviation can be converted into a uniformity index. Meanwhile, the method for analyzing the degree of shape matching is as follows: obtain the shape of the standard pit and the shape of the corresponding standard magnesium oxide particle, and obtain the degree of shape matching by dividing the volume of the intersection of the two shapes by the volume of the union of the two shapes. This can quantitatively assess the geometric compatibility of magnesium oxide particles and pits, avoiding reliance on experience alone. Here, the standard pit and standard magnesium oxide particle are the mode in statistics, that is, the shape with the most numbers among the pits and magnesium oxide particles. Furthermore, the weights for the weighted summation here are obtained through experiments using historical data. S23. Obtain environmental data affecting coating quality during the coating process. Set the standard deviation of each environmental data point from the corresponding safe range of the environmental data as the outlier of the corresponding environmental data. Sum the outliers of all types of environmental data with weights to obtain the environmental outlier. It should be noted that the standard deviation here is the difference between the environmental data and the median of the safe range divided by the difference of the safe range. The weights are obtained through experiments. The impact of each environmental change on the coating quality is obtained separately. The sensitivity of environmental fluctuations can be flexibly adjusted. For example, if the coating process is sensitive to humidity, its coefficient can be increased to make the prediction more in line with actual needs. The comprehensive formula (uniformity prediction × environmental correction) considers both substrate-particle matching (S22) and environmental interference (S23) to avoid prediction deviations caused by a single factor. For example, even if the particles and pits match well, abnormal environmental temperature may still lead to a decrease in coating quality. This formula can effectively capture such situations. S24. Multiply the obtained environmental anomaly value by the environmental impact coefficient to obtain the environmental impact result, and multiply the difference between 1 and the environmental impact result by the coating uniformity prediction analysis result to obtain the magnesium oxide adhesion prediction result. Step S3: Analyze the effect of magnesium oxide coating based on the magnesium oxide adhesion prediction results and the usage data of silicon steel during use; In this embodiment, it should be noted that the analysis of the magnesium oxide coating effect in step S3 includes the following specific contents: S31. Obtain the average force and frequency of friction and collision during the historical use of the corresponding silicon steel, as well as the adhesion strength after the corresponding magnesium oxide coating is bonded. The detachment force anomaly is obtained by dividing the average force of friction and collision during the historical use of the corresponding silicon steel by the adhesion strength after the corresponding magnesium oxide coating is bonded. The detachment frequency anomaly is obtained by the ratio of the frequency of friction and collision during use to the safe frequency. The adhesion detachment anomaly is obtained by multiplying the detachment force anomaly by the detachment frequency anomaly. The adhesion detachment anomaly assesses its dynamic risk by quantifying the degree of damage to the coating caused by external forces. The specific calculation is divided into two steps: using historical friction or collision forces (such as those during transportation)... The ratio of the impact force (and equipment vibration stress) to the adhesion strength of the magnesium oxide coating (such as the peel strength measured in the laboratory) is calculated. If the ratio is >1, it indicates that the external force has exceeded the coating adhesion, which is likely to cause peeling. If the ratio is <1, the coating is more stable. The ratio of the actual friction / collision frequency to the safe frequency (such as the number of withstand cycles specified by industry standards) is also calculated. Although the damage caused by a single high-frequency, small external force is small, the cumulative fatigue effect will accelerate the failure of the coating. The final outlier is the product of the two, which comprehensively reflects the static destructive force and the dynamic wear risk. For example, if a silicon steel experiences frequent minor collisions during transportation (abnormally high frequency), even if the force of a single collision is small (abnormally low force), the product may still indicate a high risk. S32. Obtain the reciprocal of the adhesion detachment anomaly to get the adhesion fixation coefficient. To avoid the denominator being 0 and the reciprocal being meaningless, a very small constant needs to be added to the denominator. The adhesion fixation coefficient and the magnesium oxide adhesion prediction result are weighted and summed to obtain the magnesium oxide coating effect. Step S4: Analyze the coating thickness on the silicon steel surface based on the results of the magnesium oxide coating effect analysis; In this embodiment, it should be noted that the analysis of coating thickness in step S4 includes the following specific details: S41. Obtain the magnesium oxide coating effect threshold and the coating thickness corresponding to the threshold, and at the same time obtain the magnesium oxide coating effect obtained from the analysis. S42. The required magnesium oxide coating thickness for silicon steel is obtained by multiplying the ratio obtained by dividing the magnesium oxide coating effect threshold by the corresponding magnesium oxide coating effect and the coating thickness corresponding to the threshold. In industrial production, the qualified standard for magnesium oxide coating effect is usually determined by experiments or industry specifications. For example, the coating effect of a certain silicon steel product must reach the threshold to be considered qualified, and the corresponding ideal coating thickness is 5μm±0.5μm. If the actual test finds that the coating effect does not meet the standard, the process can be adjusted by calculating the compensation thickness: First, divide the threshold by the actual effect to obtain the compensation coefficient, and then multiply this coefficient by the standard thickness to determine the new target coating thickness. This method can not only accurately repair defective batches, but also optimize the production process. Step S5: Apply magnesium oxide coating to the silicon steel surface according to the corresponding coating thickness. In this embodiment, it should be noted that step S5 involves coating the silicon steel surface with magnesium oxide according to the corresponding coating thickness, which includes the following specific details: The required magnesium oxide coating thickness for the corresponding silicon steel is compared with the actual safe coating thickness range. If the required thickness falls within this range, coating is performed according to the specified thickness. If the required thickness does not, coating is not permitted, and either the silicon steel or the magnesium oxide coating needs to be replaced. The actual safe coating thickness range is determined based on the specific application scenario or the safe coating thickness of the coating equipment. This comparison method ensures that the magnesium oxide coating meets both process requirements (such as insulation and adhesion) and the actual safe operating range of the equipment or coating, avoiding [further issues]. The reason why coating failure or equipment damage may occur due to thickness deviation is that the coating effect of silicon steel is correlated with thickness (such as experimental data or industry standards), while the safe coating range of equipment or coating is determined by physical properties (such as flowability and drying speed) or equipment parameters (such as spraying accuracy and load-bearing capacity). By dynamically matching the required thickness with the safe range, product quality (such as achieving the standard 0.75 effect) and process feasibility (such as controlling the thickness within 4.5-7μm; if it exceeds the safe range, it will prompt to replace materials or adjust the process, thus avoiding production risks from the source. For example, if a silicon steel requires 6.25μm but the equipment's safe upper limit is 6μm, the system will directly terminate the coating and prompt to replace with a high-concentration coating or upgrade the equipment, rather than forcibly executing the process and causing the coating to crack.

[0019] It should be further explained that the setting parameters in this embodiment, such as the weighting weights and thresholds, are obtained as follows: For the weighting of the weighted summation of the coating uniformity prediction analysis results in step S22, a large amount of historical data on silicon steel coating is collected. The actual influence of different shape matching degrees and matching uniformity on coating uniformity is analyzed in the historical data. Statistical analysis methods, such as regression analysis, are used to determine the reasonable proportion of the two in the final result, thereby obtaining the weighting weights. For the weighting of the weighted summation of environmental data anomalies in step S23, a series of experiments are conducted to change different environmental factors (such as temperature, humidity, etc.), observe and quantify the impact of changes in each environmental factor on coating quality, and determine the weight of each environmental data in the weighted summation based on the degree of influence. As for the magnesium oxide coating effect threshold in step S41, multiple sets of silicon steel coating experiments are conducted to simulate different coating conditions and effects. Combined with the qualified standards of industrial production, industry specifications, and actual product usage requirements, a coating effect value that can ensure the silicon steel coating quality meets the expected requirements is determined as the threshold. In this embodiment, it is important to note that it offers the following advantages: It acquires data on the silicon steel surface, usage, coating environment, and coating itself. Through steps such as coating condition prediction, magnesium oxide adhesion prediction, coating effect analysis, and coating thickness analysis, it accurately determines the magnesium oxide coating thickness on the silicon steel surface. In the magnesium oxide adhesion prediction, it comprehensively considers the shape and size matching of pits on the silicon steel surface and magnesium oxide particles, as well as environmental factors, avoiding prediction deviations caused by a single factor. The coating effect analysis combines the historical friction and collision conditions of the silicon steel with the coating adhesion to assess dynamic risks. The coating thickness analysis accurately calculates the required coating thickness based on the coating effect threshold. Finally, it compares the required coating thickness with the safe range to ensure that the coating meets both process requirements and actual operating conditions, mitigating production risks from the source and guaranteeing product quality and process feasibility.
