Description

Technical Field

[0001] The present invention relates to the technical field of steel billet production, and in particular to a method and system for self-adapting adjustment of steel billet production parameters. Background Art

[0002] In the production process of steel billets, process parameters (such as temperature, drawing speed, cooling speed, etc.) have an important impact on product quality, production efficiency and energy consumption. However, traditional parameter adjustment methods usually rely on manual experience or static rules, which are difficult to adapt to the complexity and dynamics of production conditions, resulting in low adjustment efficiency, delayed response and limited optimization effect. In addition, when faced with multi-parameter high-dimensional search space, traditional optimization methods have problems such as low optimization efficiency, easy to fall into local optimality, lack of dynamic adjustment ability and inability to effectively utilize historical production experience, which makes it difficult to meet the needs of modern steel manufacturing for efficient and intelligent production.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0021] Embodiment 1 like Figure 1 As shown, the present application provides a method for adaptively adjusting production parameters of steel billets, the method comprising: S10: Setting production data observation points to obtain production process parameters, and arranging the production process parameters to generate an original parameter group; S20: calculating the initial pheromone value of each original parameter group, and obtaining the heuristic factor according to the initial pheromone value and the production process parameters; S30: Aggregating the initial pheromone values ​​to obtain the pheromone concentration, and using the pheromone concentration and the heuristic factor as adaptive conditions to establish a production parameter adaptive model; S40: Obtain a final solution combination of production parameters according to the production parameter adaptive model.

[0022] Specifically, production data observation points are set up, sensors are arranged at key process nodes (such as casting, rolling, and cooling stages) in steel billet production, and production process parameters, including temperature, drawing speed, cooling speed and other process parameters, are collected and organized into original parameter groups, which are generally a multidimensional vector set; based on the performance of each original parameter group in historical production data, its contribution to the target production index (such as product quality, energy consumption, and efficiency) is calculated as the initial pheromone value; based on the initial pheromone value of the original parameter group and in combination with production conditions, a heuristic factor is generated; based on the similarity between the current production conditions and the historical best parameter combination, the weight of the initial pheromone value is adjusted; the parameter combinations with similar initial pheromone values ​​are grouped through a clustering algorithm, and the comprehensive analysis of each group is carried out. The heuristic factors are generated based on the characteristics, and the heuristic factors are normalized to ensure that the weights of different parameters are comparable; the initial pheromone values ​​of each original parameter group are aggregated to generate the overall pheromone concentration to represent the global adaptability of the parameter combination under the current production environment; the pheromone concentration and heuristic factors are used as input to establish a production parameter adaptation model, and the production parameter adaptation model is optimized based on the ant colony algorithm; through multiple iterative optimizations, under the condition of fitness convergence, the parameter combination with the highest fitness value is selected as the final solution combination of production parameters; the obtained final solution combination is applied in actual production, the production effect is monitored in real time, and the pheromone concentration and heuristic factors are dynamically adjusted according to the deviation of production data to ensure the robustness and adaptability of the production parameter model under different conditions.

[0023] The technical solution of the present invention effectively solves the problems of low parameter optimization efficiency, insufficient real-time adjustment capability and low utilization rate of intelligent experience in steel billet production, accelerates the optimization process, and thus improves the quality, efficiency and cost control level of steel billet production.

[0024] Further, if Figure 2 As shown, the final solution combination of production parameters is obtained, including: Based on the initial pheromone values ​​and heuristic factors of each original parameter group, a candidate solution of parameter combination is established; Each parameter combination candidate solution determines a production parameter combination path according to the corresponding pheromone concentration and heuristic factor; Calculate the fitness value for each production parameter combination path, and give priority to exploring the production parameter combination path with the highest fitness value at the same level; Iteratively execute the selection of production parameter combination path and the calculation of fitness value until the fitness value convergence condition is met; At the end of the iteration, the parameter combination candidate solution contained in the production parameter combination path with the highest fitness value is selected to generate the final production parameter solution combination.

[0025] As a preferred embodiment of the above, multiple parameter combination candidate solutions are generated based on the original parameter group, combined with the initial pheromone value and the heuristic factor. Each parameter combination candidate solution is composed of different production parameter combinations, including process parameters such as temperature range, drawing speed range, cooling speed range, etc. Through the random initialization method, several initial parameter combinations are generated in the parameter search space as candidate solutions. Combined with historical data and current production conditions, the initial pheromone value of the candidate solution is assigned; each parameter combination candidate solution determines its path selection in the production process according to the corresponding pheromone concentration and heuristic factor. The probability of the path is determined by the following formula: in P ij Represents a slave node i Move to Node j The probability of τ ij Indicates the path ij The pheromone concentration on η ij Indicates the path ij The heuristic factor, α , βare the weight factors of pheromone concentration and heuristic factor respectively; for each production parameter combination path, the fitness value is calculated based on the fitness function to measure the performance of the path under the target production index (such as quality, efficiency, energy consumption), and the production parameter combination path with the highest fitness value among the paths of the same level is explored first, and the path selection is guided by the high fitness value of the path; iterative optimization is performed, and the selection of production parameter combination paths and the calculation of fitness values ​​are repeated until the convergence condition of the fitness value is met. In each iteration, the pheromone concentration on the path is updated to increase the pheromone concentration of the high fitness path and gradually evaporate the pheromone concentration of the low fitness path, thereby strengthening the ant's exploration tendency for the optimal path; at the end of the iteration, the parameter combination candidate solution contained in the production parameter combination path with the highest fitness value is selected as the final production parameter final solution combination, and the production parameter final solution combination includes the optimal process parameter settings, such as optimal temperature, drawing speed, cooling speed, etc.

[0026] More specifically, the selection of the production parameter combination path is performed iteratively, including: The pheromone concentration on the production parameter combination path is updated according to the fitness value; The fitness of each production parameter combination path is compared, and the pheromone concentration corresponding to the high fitness value increases, while the pheromone concentration corresponding to the low fitness value gradually evaporates; The pheromone concentration results of each production parameter combination path are modified according to the heuristic factors reflecting the changing trend of the production process parameters; Detect whether a local optimal solution appears. If so, perform a perturbation operation on the production parameter combination path with similar and continuous changes in pheromone concentrations; After each iteration, the changes in the fitness values ​​of the production parameter combination paths are monitored. When the rate of change is lower than the fitness value convergence condition, the iteration process is terminated and the final solution combination of production parameters is selected.

[0027] As a preferred embodiment of the above embodiment, in each iteration, the pheromone concentration on the production parameter combination path is updated according to the fitness value of the path. For the production parameter combination path with a higher fitness value, the pheromone concentration is increased, thereby increasing the probability of the path being preferentially selected and strengthening the exploration of these paths. For the production parameter combination path with a lower fitness value, the pheromone concentration is gradually reduced to reduce the selection probability of these paths, thereby guiding more resources to be concentrated on potential high-quality paths; the heuristic factor is used to evaluate the closeness of the current path to the target optimization by analyzing the difference between the current production parameters and the historical optimal parameters. If the parameter combination of a path is similar to the optimal parameter combination in the historical data, its weight is increased and its pheromone concentration is further increased. Otherwise, the weight is reduced. Through this process, the pheromone concentration update result is corrected in combination with historical experience and real-time data. The result makes the path selection more in line with the actual production. During the iteration process, it is detected whether the change of pheromone concentration tends to be continuous and similar (that is, the difference of concentration change of multiple paths is very small) to determine whether a local optimal solution appears. If the concentration change of multiple paths remains small, it means that the algorithm may fall into a local optimal solution. To avoid this problem, the paths with continuous and similar changes in pheromone concentration are disturbed, that is, the path parameter combination is randomly adjusted (offset) in a small range to generate new paths, and a small amount of pheromone is added to some low-concentration paths to break the current concentration trend, redistribute the exploration direction, and improve the global search ability. After each iteration, the fitness value changes of all paths are monitored to determine whether the convergence conditions are met. If the fitness value of the path changes very little in multiple iterations, it means that the path has stabilized and reached a convergence state. At this time, the iteration process is stopped, and the production parameter combination contained in the path with the highest fitness value is selected as the final optimization result, and the path is defined as the final solution combination of production parameters.

[0028] Specifically, the perturbation operation is performed on the production parameter combination paths with similar and continuous changes in pheromone concentrations, including: A disturbance factor is set for each production parameter combination path with similar and continuous changes in pheromone concentration. The disturbance factor is set according to the stability of the change in pheromone concentration. Based on the disturbance factor, the production parameter combination path is offset and disturbed to generate a disturbance combination path; The disturbance intensity of the disturbance combination path is adjusted according to the fitness value, and the disturbance intensity is reduced for the disturbance combination path with improved fitness value; The fitness value of the disturbance combination path is evaluated. When the evaluation result is higher than the fitness value of the corresponding production parameter combination path, the path is replaced and the pheromone concentration is updated.

[0029] As a preferred embodiment of the above embodiment, a disturbance factor is set for each production parameter combination path with similar and continuous changes in pheromone concentration to break the similarity of the production parameter combination paths. When the concentration changes of multiple production parameter combination paths tend to be consistent and the difference in fitness values ​​is small (that is, the path performance tends to be stable but has not reached the global optimum), the disturbance operation is triggered and the disturbance factor is set. The disturbance factor is dynamically set according to the stability of the pheromone concentration change. The higher the stability, the greater the intensity of the disturbance factor. Based on the disturbance factor, the production parameter combination paths with similar and continuous pheromone concentrations are offset and disturbed to generate a new disturbance combination path. On the basis of the original production parameter combination path, some parameter values ​​are randomly adjusted in a small range (such as increasing or decreasing the temperature by a small range, and the pulling speed fluctuates up and down by a certain proportion), and a new production parameter combination path after disturbance is generated. A random disturbance factor is introduced on the basis of the offset of the production parameter combination path. According to the disturbance, The fitness value adjusts the disturbance intensity to optimize the disturbance efficiency; when the fitness value of the production parameter combination path after the disturbance is higher than the fitness value of the original production parameter combination path, the disturbance intensity is reduced to gradually converge to avoid excessive random disturbance affecting the accuracy of the final solution; when the fitness value of the production parameter combination path after the disturbance is lower than the fitness value of the original path, the disturbance intensity is increased to further expand the search range and explore potential high-quality paths; the fitness value of the generated disturbance combination path is evaluated and compared with the fitness value of the original path. Based on the production objectives (such as product quality, efficiency and energy consumption), it is evaluated whether the disturbance path can show better results in the objective function. If the fitness value of the disturbance path is higher than the corresponding original production parameter combination path, the original production parameter combination path is replaced with the disturbance combination path, and the pheromone concentration of the disturbance combination path is updated. The updated pheromone concentration will reflect the new fitness value to guide subsequent iterations to explore better paths.

[0030] Further, if Figure 3 As shown, the heuristic factors are obtained according to the initial pheromone values ​​and production process parameters, including: Analyze the initial pheromone of the original parameter group under each production target. The initial pheromone is determined based on the impact of the original parameter group on the production target. The initial pheromone is quantified to generate the initial pheromone value, and the initial heuristic factor is generated by combining the original parameter group; Obtain the historical parameter group, and assign corresponding influence weights to the initial heuristic factors based on the similarity between the original parameter group and the historical parameter group; Cluster the initial heuristic factors, combine the initial heuristic factors with similar influence weights, and analyze the similarities between groups; The initial heuristic factors were weighted according to the similarities between groups, and the heuristic factors were obtained by integrating the weighted correction results.

[0031] As a preferred embodiment of the above, by analyzing the influence of the original parameter group (such as temperature, drawing speed, cooling speed, etc.) on different production targets (such as quality, efficiency, energy consumption), the initial pheromone of each original parameter group is determined, and the contribution of each parameter group to the production target is classified and captured. The more significant the impact of the parameter, the higher its initial pheromone value; conversely, the parameter with less impact corresponds to a lower pheromone value; the captured initial pheromone is quantified to generate an initial pheromone value in a unified format. The positive and negative effects of the parameters on the production target need to be considered in the quantification process (for example, increasing the temperature may increase energy consumption but improve product quality). The initial heuristic factor of each parameter combination is calculated by combining the quantized initial pheromone value and the original parameter group. The heuristic factor is used to reflect the influence trend of the production parameter on the target optimization direction; the historical parameter group similar to the current production conditions is extracted. The historical parameter group records the parameter settings in the production process and their influence on the target. The initial parameter group is matched with the historical parameter group for similarity. The higher the matching degree of the historical parameters, the more significant the impact on the initial heuristic factors. According to the matching results, the initial heuristic factors are assigned corresponding influence weights to make them more suitable for the current production goals. The initial heuristic factors are clustered and the factors with similar influence weights are divided into several groups. Each group represents a parameter combination with similar contributions in the production goal optimization. The similarities between different clustering groups are further analyzed, and the degree of difference between groups is calculated to identify factor groups with potential global optimization capabilities. Groups with high similarity between groups are assigned higher comprehensive weights to highlight their importance in target optimization. For groups with low similarity between groups, their weights are reduced to reduce their interference in the generation of the final factors. The initial heuristic factors with modified weights are normalized and integrated to generate the final heuristic factors. The heuristic factors combine the best matching results of current production conditions and historical experience and have dynamic adaptability.

[0032] Furthermore, the initial heuristic factors are weighted according to the similarity between groups, including: For the initial heuristic factor within each cluster grouping, calculate the similarity measure within the group, and adjust the data distribution between groups according to the similarity measure; Analyze the differences in data distribution between different cluster groups, assign comprehensive correction weights to cluster groups with similarity matching according to the differences in similarity between groups, and screen out cluster groups with low similarity; Based on the difference results of inter-group similarity and the comprehensive correction weight, the initial heuristic factors of each cluster grouping are globally modified; The global weight correction is a weighted combination of the comprehensive correction weight and influence weight of each cluster grouping to calculate the final correction weight of each initial heuristic factor; The normalized results of the final modified weights corresponding to the initial heuristic factors are integrated to obtain the heuristic factors.

[0033] As a preferred embodiment of the above, for the initial heuristic factors in each cluster grouping, the consistency of the factor characteristics in the grouping is measured by calculating the similarity measurement value between the factors in the grouping. The grouping with a higher similarity measurement value indicates that its factor characteristic concentration is higher and is suitable for further optimization. The grouping with a lower similarity measurement value may affect the accuracy of the final result. According to the similarity measurement value within the group, the data distribution between the groups is adjusted, the weight of the factors with lower similarity within the group is weakened, and the contribution ratio of the high similarity factor is increased, so that the data distribution within the group is more concentrated; compare the inter-group similarities between different cluster groups, analyze the differences in group characteristics under global production conditions, for example, determine which groups have more significant contributions to the target optimization and which groups have larger deviations. According to the inter-group similarity, the cluster groups with higher similarity matching degrees are given comprehensive correction weights, and these groups are retained first and their influence in subsequent calculations is strengthened, while the groups with similarity to other groups are screened out. The groups with low similarity and weaker contribution are selected to reduce the interference of invalid groups on the optimization process; the comprehensive correction weight is calculated for each group. The comprehensive correction weight is combined with the matching results of the similarities between groups and the impact contribution of the group on the production target as a quantification of the overall optimization ability of the group. The initial heuristic factors in each group are globally corrected by combining the comprehensive correction weight with the impact weight of the group. Specifically, according to the balance between the importance of the group and the characteristics of the factors in the group, the weight of each factor is adjusted to make it more in line with the global optimization goal; the final correction weight of each initial heuristic factor is calculated by weighted combination of the comprehensive correction weight and the impact weight. The final correction weight reflects the importance and contribution of each factor in the optimization of the production target. The final correction weight is normalized to ensure that the sum of all correction weights remains consistent, so that the weights of different factors are comparable, and the normalized final correction weight is integrated with the corresponding initial heuristic factor to generate a heuristic factor.

[0034] Further, if Figure 4 As shown in the figure, the pheromone concentration and heuristic factor are used as adaptive conditions to establish the production parameter adaptive model, including: Based on the pheromone concentration and the heuristic factor, the initial state of the production parameter adaptive model is established, and multiple parameter adjustment paths are set for the production parameter adaptive model; Set the pheromone concentration threshold, and use the change of pheromone concentration as the adaptive trigger condition of the model. When the pheromone concentration reaches the pheromone concentration threshold, adjust the heuristic factor; According to the changes of heuristic factors, multiple parameter adjustment paths are used to adaptively search the production process parameters and calculate the optimized production path; According to the optimized production path, the production parameter adaptive model is updated, and the pheromone concentration and heuristic factor are adjusted synchronously; Feedback verification is performed on the production parameter adaptive model, pheromone concentration and heuristic factors are recalculated based on the verification results, and the final production parameter adaptive model is generated after the system is stable.

[0035] As a preferred embodiment of the above embodiment, the heuristic factor and pheromone concentration are used as input parameters to construct a production parameter adaptive model. The pheromone concentration reflects the global optimization direction, and the heuristic factor reflects the real-time change trend of the production parameters. Multiple parameter adjustment paths are defined in the production parameter adaptive model. Each path corresponds to a different production parameter adjustment direction and adjustment strategy (such as temperature change path, pulling speed change path, etc.). These parameter adjustment paths will be used as the search space in the adaptive model. According to historical production experience and target production indicators (such as quality, efficiency, and energy consumption), the pheromone concentration threshold range is set. The pheromone concentration threshold is used to determine whether the current production parameters need to be adaptively adjusted. When the pheromone concentration reaches the set pheromone concentration threshold, the production parameter adaptive model will activate the adaptive adjustment mechanism and dynamically adjust the heuristic factor to reflect the changes in the current production conditions. For example, when the pheromone concentration tends to be too high or too low, the weight of the heuristic factor is adjusted to rebalance the model. The production parameters are adaptively searched using multiple parameter adjustment paths. The production parameter adaptive model gradually adjusts the parameter values ​​on the path to evaluate the impact of each adjustment on the target production indicator. According to the search results, the optimization degree of each path is calculated to optimize the production. A path refers to a path that improves the target production index (such as product quality improvement or energy consumption reduction). The model gives priority to the path with the most significant optimization effect for the next update. According to the search results of the optimized production path, the internal state of the production parameter adaptive model is updated, including adjusting the pheromone concentration and recalculating the heuristic factor. The update process ensures that the model can reflect the current production conditions in real time to avoid optimization failure caused by parameter lag. The pheromone concentration update strengthens the global search capability, and the heuristic factor correction enhances the real-time adaptability. Through the synchronous adjustment of the two, the dynamic response capability of the model to the complex production environment is improved. The updated production parameter adaptive model is applied in actual production, and production effect data (such as product quality, efficiency and energy consumption) are collected. These data are compared and analyzed with the expected results of the production parameter adaptive model to verify whether the model accurately reflects the production conditions and optimizes the target production indicators. If there is a deviation between the production effect data and the expectation, the pheromone concentration and heuristic factor are recalculated according to the verification results, and the model parameters are further optimized. When the feedback verification results show that the production effect has reached a stable state, the parameters of the production parameter adaptive model are fixed to generate the final production parameter adaptive model, and the model is applied to the subsequent production process.

[0036] Furthermore, the production parameter adaptive model is feedback-validated, including: Collect production effect data, generate a production effect data set, and establish a production experience database based on the production effect data set; Compare and analyze the production effect data set with the expected output of the production parameter adaptive model and calculate the expected deviation; According to the expected deviation, the corresponding heuristic factors are judged and the pheromone concentration is corrected to generate the expected correction result; Repeatedly collect production effect data to verify the stability of the production parameter adaptive model, and store the parameter combination and expected correction results of the verified production parameter adaptive model in the production experience database.

[0037] As a preferred embodiment of the above-mentioned embodiment, in the process of steel billet production, production effect data, including product quality (such as yield rate, surface defect rate), production efficiency (such as production rhythm) and energy consumption indicators (such as energy consumption) are collected in real time, and the collected real-time data are sorted and annotated to generate a structured production effect data set for subsequent analysis and model optimization. The production effect data set should cover the correspondence between production parameters and target indicators to support model verification; the sorted production effect data set is stored in a production experience database, which records parameter settings, production effects and optimization results under different production conditions, and provides a reference basis for subsequent similar working conditions. The production experience database is continuously updated with changes in production conditions and optimization results to ensure that it always contains the latest and optimal experience data; according to the production parameter adaptive model, the expected production effect under current conditions is calculated as the output reference value of the model, and the actual production effect in the production effect data set is compared with the expected output of the model item by item, and the deviation is analyzed. According to the comparison result, the expected deviation value between the actual production effect and the expected production effect is calculated to judge the accuracy of model optimization. The smaller the expected deviation value, the closer the model is to the actual production situation; according to the calculated The expected deviation value is used to judge the heuristic factors in the model. If the deviation value exceeds the set threshold, it means that the model fails to accurately adapt to the current production conditions and needs to be adjusted. For the production parameters with deviations, the corresponding heuristic factor weights are adjusted to make them more in line with the current production reality. According to the corrected heuristic factors, the pheromone concentration is recalculated to guide the model to give priority to the adjusted parameter path in subsequent optimization. The corrected heuristic factors and pheromone concentrations are used as expected correction results and fed back to the production parameter adaptive model. During the production process, new production effect data are continuously collected to observe the performance of the model parameters after adjustment. The collected production effect data are verified to determine whether the model can stably achieve the target production effect after adjustment. If the model performance is stable, it means that the optimization has been completed. If there is still a deviation, continue to correct and verify.
