It should be understood that such objects used in this way can be interchanged, where appropriate, to enable the embodiments of the present application described herein to be carried out in other than the order illustrated or described.

[0031] With the advent of the data-driven information age, intelligent digital models have been applied in many fields, and people's mining and application of data are increasingly mature. The performance and correlation analysis of steel has important significance for improving the quality of steel, reducing costs, and improving production efficiency. The present application is a solution that uses intelligent algorithms to convert offline analysis into online autonomous intelligent analysis. From people to data, let data do it, focusing on in-depth comprehensive analysis of relevant process parameters of steel performance, quickly finding and positioning the root cause of problems affecting the quality of steel, shortening the time-consuming of problem processing, and assisting enterprises to master steel information, prevent steel quality defects, and improve steel quality.

[0032] The implementation details of the technical solutions of the embodiments of the present application are described in detail as follows:

[0033] Referring to Figure 1 , Figure 1 is a steel coil performance data control method flowchart in an embodiment of the present application.

[0034] According to a typical embodiment of the present application, a steel coil performance data control method is provided, which includes the following steps S1 to S4:

[0035] Step S1, obtaining historical production data of each steel coil production line in the historical production process, the historical production data including strip composition parameters and a plurality of process parameters in the process of producing steel coils from strips as historical process parameters.

[0036] In the present application, before performing the correlation analysis of the performance of the steel coil and the production data of the steel coil, a large amount of data needs to be based on digital analysis, so that the analysis result has data support. First, the historical production data of each steel coil in the historical production process is obtained from the steel coil production line, the historical production data can be saved to the control system after the strip is produced and coiled into a coil, the historical production data can include strip composition parameters and a plurality of process parameters in the process of producing steel coils from strips, and the plurality of process parameters are used as historical process parameters.

[0037] Step S2, obtaining performance parameters of the steel coils produced by each steel coil production line in history as historical performance parameters.

[0038] In the present application, in order to analyze the correlation between the performance of the steel coil and the production data of the steel coil, in addition to obtaining each historical production data on the steel coil production line, the performance parameter of each steel coil produced on the historical production line also needs to be obtained. In the historical production, each steel coil corresponds to a performance parameter (the performance parameter can include multiple parameters), and the performance parameter can represent the quality of the produced steel coil. After obtaining the performance parameter, the performance parameter is taken as the historical performance parameter.

[0039] Step S3: constructing a steel performance prediction model by performing correlation analysis on the historical performance parameter and the historical production data.

[0040] In the present application, after obtaining the historical performance parameter and the historical production data, a steel performance prediction model can be constructed by performing correlation analysis on the historical performance parameter and the historical production data. The steel performance prediction model can perform performance prediction on the steel coil.

[0041] Step S4: in the online production process, the performance data of the steel coil to be produced is controlled by the steel performance prediction model.

[0042] In the present application, after the steel performance prediction model is established, it can be applied to online production. In the online production process of the steel coil, the performance data of the steel coil to be produced can be controlled by the steel performance prediction model to ensure that the final quality of the steel coil to be produced meets the product quality standard.

[0043] In an embodiment of the present application, before performing correlation analysis on the historical performance parameter and the historical production data, the method further comprises:

[0044] The correlation analysis on any two parameters in the historical production data and the historical performance parameter is performed by using the lasso algorithm to obtain a correlation analysis result.

[0045] According to the correlation analysis result, the noise parameters in the historical production data are removed.

[0046] In the present application, since the obtained historical production data and historical performance parameters can be thousands of data, data redundancy and abnormal data can easily occur when obtained, therefore, before performing correlation analysis on the historical performance parameters and the historical production data, the disordered data needs to be formed into mean consistent data, integrated into plan standard value, integrated into performance data, constructed into curve alignment data or constructed into sampling position data (which can digitize steel, quickly lock process parameters affecting steel quality, and provide relevant data based on steel performance) according to different needs, and then the historical production data and the historical performance parameters are obtained from the sorted data.

[0047] In the present application, before performing correlation analysis on the historical performance parameters and the historical production data, the lasso algorithm can also be used to perform correlation analysis on any two parameters in the historical production data and the historical performance parameters to obtain a correlation analysis result. For example, when the historical production data contains three data A, B and C, and the historical performance parameters contain two parameters D and E, if data A increases, data B also increases, and the increase of data A and data B also affects parameter D, it indicates that data A, data B and parameter D have correlation, but since data A and data B also have correlation and belong to the same type of data, to avoid data redundancy, one data is selected from data A and data B, and the other is eliminated (the eliminated one can be a noise parameter); if data C increases or decreases, no matter how data C changes, it has little or even no effect on parameter D or parameter E, then data C (noise parameter) is also eliminated, so that the obtained historical production data and historical performance parameters can be simplified to avoid data redundancy and abnormal data.

[0048] In the present application, it is noted that the data A, data B and data C can be any item in the historical production data, such as tapping temperature, finishing temperature, tapping temperature, or other items, and the parameter D and parameter E can be any item in the historical performance parameters, such as yield strength and elongation, or other items, which are not particularly limited in the present application and can be adjusted according to actual production.

[0049] In the present application, after the historical production data is obtained, the historical process parameters in the historical production data can be matched by the operation system in terms of curve topography characteristics, and the matched curve topography characteristics can be stored in a curve feature library. The historical process parameter data can be intuitively displayed in a chart manner, and typical process parameter curves can be added to the curve feature library or the process parameter curves in the curve feature library can be changed, so as to facilitate analysis and comparison with subsequent curves, so as to realize data systematization and automation such as query, analysis, arrangement and export.

[0050] In an embodiment of the present application, the constructing a steel performance prediction model by performing correlation analysis on the historical performance parameters and the historical production data comprises:

[0051] The correlation analysis on the historical performance parameters and the historical production data is performed by an adaptive boosting algorithm, an extreme tree algorithm, a gradient boosting algorithm and a random forest algorithm respectively, and a plurality of candidate steel performance prediction models are constructed.

[0052] The steel performance prediction model is selected from the plurality of candidate steel performance prediction models.

[0053] In the present application, after the noise parameters in the historical production data are removed according to the correlation analysis results, the historical performance parameters become concise, which is beneficial to reduce the workload when constructing a model. If the historical performance parameters are more lengthy and complex, the constructed model is also more complex and redundant. Removing the noise parameters in the historical production data has a great beneficial effect on constructing a model.

[0054] In the present application, the correlation analysis on the historical performance parameters and the historical production data can be performed by a regression algorithm such as an adaptive boosting algorithm, an extreme tree algorithm, a gradient boosting algorithm and a random forest algorithm, and a plurality of candidate steel performance prediction models are constructed. After the candidate steel performance prediction models are established, they are displayed in three forms of key process parameters and importance, key process thermodynamic diagrams and modeling evaluation results. The plurality of candidate steel performance prediction models can be displayed by visualization to show which key process parameters they are composed of, and the importance of the key process in the plurality of processes in the entire steel strip production process, as well as the key process thermodynamic diagram and the modeling evaluation result. The steel performance prediction model can be selected from the plurality of candidate steel performance prediction models according to the modeling evaluation result. The evaluation result is used to evaluate the accuracy of the plurality of candidate steel performance prediction models in evaluating the performance of the steel coil. The steel performance prediction model with the optimal evaluation result is selected from the plurality of candidate steel performance prediction models.

[0055] In the present application, it is noted that the user or operator can autonomously select the data required for model establishment and the key process parameters of the model when performing manual operation to perform online modeling. The established model can also be displayed in three forms of key process parameters and importance, key process thermodynamic map and modeling evaluation results.

[0056] In an embodiment of the present application, the performance data of the to-be-produced steel coil controlled by the steel performance prediction model comprises:

[0057] Obtaining a target performance parameter of a to-be-produced steel coil;

[0058] Based on the target performance parameter, determining a target strip steel composition parameter and each target process parameter for producing the to-be-produced steel coil by the steel performance prediction model;

[0059] Performing production of the to-be-produced steel coil according to the target strip steel composition parameter and the each target process parameter.

[0060] In the present application, after the steel performance prediction model is established, the performance data of the to-be-produced steel coil can be controlled by the steel performance prediction model. In actual use, the target performance parameter of the to-be-produced steel coil, i.e., the performance parameter of the final product required by the production plan, can be obtained first. After the target performance parameter is obtained, the target strip steel composition parameter and each target process parameter for producing the to-be-produced steel coil are determined based on the target performance parameter by the steel performance prediction model, so that the production line performs production of the to-be-produced steel coil according to the target strip steel composition parameter and the each target process parameter. When the production of the to-be-produced steel coil is performed according to the target strip steel composition parameter and the each target process parameter, the product corresponding to the previously obtained target performance parameter can be obtained, and the quality of the steel coil product can be a qualified product.

[0061] In an embodiment of the present application, the method further comprises:

[0062] During the production of the to-be-produced steel coil, if any one or more process parameters deviate from the corresponding target process parameter, the steel performance prediction model is used to adjust the process parameters other than the any one or more process parameters in the each target process parameter, and the production of the to-be-produced steel coil is performed according to the adjusted process parameters.

[0063] In the present application, if the production of the target steel strip composition parameters and the target process parameters is performed, the final product will be a qualified product, but in actual production, various interference factors may cause any one or more process parameters to deviate from the corresponding target process parameters during production. If the parameters are not adjusted, the final product may be a non-qualified product, which may also affect the production efficiency of the product or cause production failure, causing damage to the equipment of the production line.

[0064] In the present application, after obtaining the target performance parameters to be produced, the target steel strip composition parameters and the target process parameters for producing the target steel strip are determined based on the target performance parameters through the steel performance prediction model, the target process parameter curve is generated through the operation system, the curve data in the feature library are extracted through the high-frequency time sequence data feature extraction algorithm, the minimum distance is calculated through the multi-template comprehensive similarity distance, and the curve features are automatically matched (as shown in Figure 2 、 Figure 3 The corresponding curve with the highest similarity can be selected for production according to the process parameters of the corresponding curve. The performance prediction result, the level of the curve, and the automatic matching of the curve level in the standard library can be displayed in the operation system.

[0065] In the present application, in order to avoid the above problems, if any one or more process parameters deviate from the corresponding target process parameters during the production of the target steel strip, the process parameters other than the any one or more process parameters are adjusted through the steel performance prediction model, for example, three process flows are required for producing the target steel strip, the first process is performed from the beginning to the end of the process, and there is no phenomenon of process parameter deviation from the corresponding target process parameter, but the phenomenon of process parameter deviation from the corresponding target process parameter occurs during the second process. In order to ensure that the target performance parameters are not affected, the process parameters of the third process need to be adjusted through the steel performance prediction model before the third process is performed, so that the final target performance parameters do not change, and the third process is performed according to the adjusted process parameters to produce the target steel strip, so that the final product of the target steel strip is a qualified product.

[0066] In the present application, not only can the steel performance result be predicted according to the position of a point of the steel strip (a point can be selected in the steel strip to obtain the corresponding process and process parameters of the point), but also the steel performance can be predicted through the mean data of the steel strip, the length direction curve of the steel strip is predicted, and the mean prediction of the steel strip and the prediction curve display of the length direction performance index are displayed (as shown in Figure 4The tensile strength prediction display of the steel coil shows that the prediction model evaluation result is displayed by accuracy, mean square error, sample size, bias scatter plot and bias distribution histogram, and the abnormal data existing in the model prediction can be inquired. The application also establishes the adjustment suggestion combined with the calculation rate of the system process adjustment scheme and the artificial suggestion strategy, to ensure the accuracy and efficiency of the steel performance judgment.

[0067] In an embodiment of the present application, the process parameters can at least include hot rolling furnace time, discharge temperature, finishing temperature, coiling temperature, deformation amount, cold rolling annealing temperature. It should be noted here that the process parameters can also include other process parameters for producing steel strips, such as coiling temperature, rolling temperature, etc., which are not particularly limited in the present application.

[0068] In an embodiment of the present application, the performance parameters can at least include tensile strength, yield strength, elongation, hardness index. It should be noted here that the performance parameters can also include nominal thickness, etc., which are not particularly limited in the present application.

[0069] In the present application, data can also be maintained, such as setting the upper and lower limits of the data when acquiring the data, so as to accurately acquire the data and avoid abnormal data from pouring in, and the performance item prediction accuracy threshold condition can also be maintained, and the data can be modified. When the accuracy of the steel performance prediction model is lower than the prediction accuracy threshold, the steel performance prediction model can be maintained and the data can be modified.

[0070] In the present application, the performance prediction of the steel coil to be produced by the steel prediction model can also be pushed through the enterprise WeChat, and the production state of the steel coil can be understood in real time
