Description

Technical Field

[0001] This invention relates to the field of graphite molding control technology, and in particular to a carbon graphite product molding control system and method based on multi-parameter coordination. Background Technology

[0002] The molding process for carbon graphite products is a crucial step in the carbon graphite production process, shaping raw materials into preforms with specific shapes, sizes, and densities. Its core principle is to use external force to densify and shape the plastic raw material within a mold, providing a qualified preform for subsequent processes such as calcination and graphitization. This process directly affects the key properties of the final product, including density, strength, and structural uniformity, and is widely used in the production of graphite products.

[0003] The main process of molding can be divided into several stages, including raw material preparation, mixing, and molding. However, the current molding process suffers from the following problems: First, there are numerous process parameters in each stage, and the lack of a unified coupling mechanism between these parameters leads to uncontrolled process stability. Second, there is a lack of a collaborative compensation mechanism between parameters in each stage. Third, real-time monitoring data in each stage cannot be fed back in a timely manner. These problems make it impossible to guarantee the quality of the paste, the molding process, and batch consistency, ultimately resulting in defects such as cracks, dimensional deviations, out-of-roundness, and quality fluctuations, severely affecting the quality of graphite products.

[0059] Example 1

[0060] In existing technologies, the main process of molding can be divided into several steps such as raw material preparation, mixing, and molding. However, the current molding process has the following problems: First, there are many process parameters in each step, and there is no unified coupling mechanism between the parameters in each step, which leads to the loss of process stability control. Second, there is no collaborative compensation mechanism between parameters in each step. Third, real-time monitoring data in each step cannot be fed back in a timely manner.

[0061] Therefore, this application provides a carbon graphite product molding control system based on multi-parameter coordination, such as... Figure 1As shown, it includes:

[0062] Process parameter setting unit: Sets corresponding initial process parameters for each processing step in the carbon graphite product molding process;

[0063] Real-time monitoring unit: Each processing stage is equipped with corresponding monitoring equipment, which simultaneously acquires real-time monitoring data;

[0064] Feedback compensation unit: Based on the real-time monitoring data, adjusts the corresponding initial process parameters in each processing stage to obtain real-time process parameters;

[0065] Process parameter adjustment unit: Based on the real-time process parameters and corresponding initial process parameters in each processing stage, determine whether there is a change ratio between the real-time process parameter and the corresponding initial process parameter in a single processing stage that exceeds the set value. If so, record the corresponding process parameter as the main process parameter and the remaining process parameters as the secondary process parameters, and use each main process parameter to adjust all secondary process parameters in sequence. If not, do not take any action.

[0066] Process parameter coupling unit: Based on the processing sequence of the processing steps, it obtains the adjusted real-time process parameters in the initial processing step and integrates them to obtain the initial processing result. Based on the initial processing result, different influence coefficients are set for all subsequent processing steps.

[0067] In all subsequent processing stages except the final processing stage, any processing stage is selected and denoted as an intermediate processing stage. The adjusted real-time process parameters of the intermediate processing stage are obtained and integrated with the influence coefficients transmitted by all upstream processing stages located in the intermediate processing stage to obtain the intermediate processing result. Based on the intermediate processing result, different influence coefficients are set for all downstream processing stages located in the intermediate processing stage.

[0068] The real-time process parameters, adjusted in all processing stages, are dynamically adjusted in conjunction with all received influence coefficients.

[0069] In particular, corresponding initial process parameters are set for each processing step in the carbon graphite product molding process. The processing steps include raw material preparation, raw material mixing, molding, and blank processing. Initial process parameters are set for each processing step, such as conveyor belt speed, mixing machine processing power, mold cavity temperature, mold cavity pressure, and mold preheating power. The setting logic is set using prior data.

[0070] Each processing stage is equipped with corresponding monitoring equipment to simultaneously acquire real-time monitoring data. This data is used to adjust the initial process parameters at each stage, establishing a feedback mechanism for adjusting initial process parameters based on real-time monitoring data. For example, a laser particle size analyzer monitors the particle size distribution of raw materials in real time, adjusting the conveyor belt speed and the sampling frequency of the weighing sensor; an ambient humidity sensor monitors humidity data in real time, adjusting the amount of binder (coal tar pitch) added; multiple infrared temperature sensors are deployed on the inner wall of the mixer to monitor internal temperature data in real time, adjusting the power of the heating zones; and online... A viscosity counter monitors viscosity data in real time and adjusts the kneading time to prevent insufficient plasticization. Thermocouples and temperature sensors are embedded at key points in the mold, and the initial temperature is automatically set, stabilizing the mold cavity temperature within a controllable range. Pressure sensors monitor the pressure in different areas of the mold cavity in real time, adjusting the pressure of the hydraulic cylinder zones. A laser displacement sensor detects the blank height and adjusts the corrected holding time. Micro-strain gauges are embedded in key contact surfaces of the mold head to compensate for the compression displacement. An outdoor temperature sensor monitors environmental data and adjusts the mold preheating time.

[0071] In this embodiment, the initial processing parameters in each processing stage are adjusted based on real-time monitoring data. The specific adjustment logic is as follows: all real-time monitoring data within a certain time interval are obtained, and a curve of the real-time monitoring data changing with time is constructed and fitted to obtain the curvature value of the corresponding real-time monitoring data. The process parameters are then adjusted. In other words, a feedback adjustment model is established and trained using the curvature of the real-time monitoring data and the corresponding process parameters to adjust the process parameters.

[0072] In this embodiment, a unified feedback adjustment logic is set for the initial process parameters based on real-time monitoring data, and specific feedback adjustment logic can also be set according to different real-time monitoring data.

[0073] For example, a material density-particle size feedback model can be constructed. Real-time monitoring of raw material particle size distribution data using a laser particle size analyzer is input into the model, automatically adjusting the conveyor belt speed and the weighing sensor sampling frequency. Since the particle size distribution of the raw material directly affects its bulk density—for example, smaller particles result in a larger bulk density, and vice versa—smaller particles with a larger bulk density may cause the weight of material passing through the weighing area per unit time to exceed the limit at the same conveying speed. This could lead to weighing sensor overload or data fluctuations. Therefore, it is necessary to reduce the conveyor belt speed and increase the weighing sensor sampling frequency. Similarly, for raw materials with larger particle sizes, it is necessary to increase the conveyor belt speed and decrease the weighing sensor sampling frequency.

[0074] For example, based on environmental humidity sensor data, the amount of adhesive added can be dynamically adjusted. The adjustment algorithm uses: , Add based on the baseline amount, This is humidity deviation data. Humidity coefficient To adjust the amount added.

[0075] If a laser displacement sensor is used to monitor the billet height, the billet's corrective holding time can be adjusted. The adjustment algorithm is as follows: , For high correction factor, For height deviation, As the baseline holding time, To adjust the holding time.

[0076] If micro-strain gauges are embedded in the critical contact surfaces of the mold, the compression molding displacement can be automatically compensated. The adjustment logic is as follows: calculate the wear coefficient, calculate the amount of compression molding displacement to be compensated. , The wear coefficient is... This is the amount of compensation.

[0077] Specifically, based on the real-time process parameters and corresponding initial process parameters in each processing stage, it is determined whether there is a ratio between the real-time process parameters and the corresponding initial process parameters in a single processing stage that exceeds a set value.

[0078]

[0079] The change ratio value, For real-time process parameters, For the corresponding initial process parameters;

[0080] If the change rate of a real-time process parameter exceeds the set value, it indicates that the adjustment range of the corresponding real-time process parameter is large. For a single processing stage, a large adjustment range of a single process parameter will affect other process parameters. For example, in the raw material pretreatment stage, if the adjustment range of the conveyor belt speed and the weighing sensor sampling frequency is large, it means that the particle size of the raw material is either too large or too small. In this case, the amount of binder added per unit volume and the processing temperature of the paste need to be adjusted accordingly. In this case, the conveyor belt speed and the weighing sensor sampling frequency are the primary process parameters, while the amount of binder added per unit volume and the processing temperature of the paste are the secondary process parameters. It should be noted that the primary and secondary process parameters in a single processing stage are only distinguished by the magnitude of the adjustment, not by fixed parameters.

[0081] Specifically, the main process parameters in a single processing step are used to adjust all secondary process parameters. This involves: using historical and prior data to construct a correlation model between a single process parameter and other process parameters. Since both the main and secondary process parameters change in a single processing step, there are multiple correlation models for a single processing step; and obtaining any one main process parameter and its corresponding correlation model to adjust the remaining secondary process parameters.

[0082] Based on the processing sequence of the processing stages, the processing stages are processed sequentially. For example, processing stages B, C, D, and E are set. Each processing stage acquires adjusted real-time process parameters. It should be noted that the adjusted real-time process parameters refer to the process parameters after primary adjustment based on real-time monitoring data and secondary adjustment based on the main process parameters.

[0083] Processing step B serves as the initial processing step. All adjusted real-time process parameters for processing step B are acquired. These parameters are then normalized under the same data protocol to obtain a multi-parameter feature set. This eliminates dimensional and magnitude differences between parameters, providing a unified analytical benchmark for extracting the distribution characteristics of parameters in a single processing step. Next, all multi-parameter feature sets for processing step B within a second time interval (e.g., three months) and the corresponding processing quality index data for that processing step are acquired, and the parameter distribution characteristics are extracted simultaneously. A mapping table between the parameter distribution characteristics and the corresponding processing quality index data is established. Using this mapping table and the adjusted real-time process parameters, the corresponding processing quality index data is output. The above processing logic involves normalizing the real-time process parameters of the processing step, extracting parameter distribution characteristics, and establishing a mapping table with prior processing quality index data. This allows for the direct output of the corresponding processing quality index data as the distribution characteristics of the real-time process parameters after the adjusted real-time process parameters are subsequently acquired.

[0084] Obtain the processing quality index data of processing stage B and the remaining processing stages within the third time interval. Construct and train a quantitative model for adjusting the corresponding process parameters of the remaining processing stages. Using the trained quantitative model, output the influence coefficients on the remaining processing stages, such as setting an influence coefficient for processing stage C. Influence coefficients are set for processing steps. Influence coefficients are set for processing steps. .

[0085] Similarly, the remaining processing steps C, D, and E are processed sequentially. Steps C and D are considered intermediate processing steps, and their processing logic is consistent with that of the intermediate processing steps. The adjusted real-time process parameters of the intermediate processing steps are obtained and multiplied by the influence coefficients transmitted from the upstream processing steps to obtain the corrected real-time process parameters. Then, combined with the corresponding mapping table, the processing quality index data of the intermediate processing steps are output. Finally, the influence coefficients of downstream processing steps are set using the quantitative model of the intermediate processing steps. For example, based on the intermediate processing results of processing step C, an influence coefficient is set for processing step D. An influence coefficient is set for processing step E. Based on the intermediate processing results of processing step D, an influence coefficient is set for processing step E. .

[0086] Finally, the adjusted real-time process parameters in all processing stages are dynamically adjusted based on all received influence coefficients. Specifically: processing stage B receives the adjusted real-time process parameters but takes no action; processing stage C receives the adjusted real-time process parameters... Therefore, the real-time process parameters after dynamic adjustment should be: Processing step D obtains the adjusted real-time process parameters as follows: Therefore, the real-time process parameters after dynamic adjustment should be: The processing stage E obtains the adjusted real-time process parameters as follows: Therefore, the adjusted real-time process parameters should be: In this embodiment, the coupling logic for multi-parameter coupling of each processing stage is to convert the distribution characteristics of processing parameters in the preceding processing stage into corresponding processing quality index data, and then use the processing quality index data to set an influence coefficient on the degree of influence of the subsequent processing stage. The influence coefficients transmitted by the subsequent processing stage to all upstream processing stages are superimposed, thereby adjusting the real-time process parameters and realizing the coupling and unification of multiple parameters among each processing stage.

[0087] In this embodiment, an environment-initial process parameter database is also established. By utilizing the different outdoor ambient temperatures, the process parameter mode is switched, and different initial process parameters are set accordingly.

[0088] In some embodiments, based on the real-time monitoring data, the corresponding initial process parameters in each processing stage are adjusted to obtain the real-time process parameters, including:

[0089] Acquire all real-time monitoring data within the first time interval and construct a curve showing the change of real-time monitoring data over time;

[0091] Based on the changed curvature value, the process parameters corresponding to the real-time monitoring data are adjusted to obtain the real-time process parameters.

[0092] In some embodiments, determining whether there is a change ratio between real-time process parameters and corresponding initial process parameters in a single processing step that exceeds a set value includes:

[0093] The following formula is used to calculate the ratio of change between real-time process parameters and corresponding initial process parameters:

[0099] Obtain the association model corresponding to the main process parameters in the first processing step, and record the corresponding main process parameters as the first main process parameters;

[0100] After inputting the first master process parameter and the remaining slave process parameters into the corresponding association model, the adjusted slave process parameters are output, thus completing the adjustment of the remaining slave process parameters.

[0108] Based on the initial processing results, the corresponding processing quality index data is obtained and recorded as the first processing quality index data;

[0109] Based on all the first processing quality index data and the corresponding processing quality index data of the remaining processing steps within the third time interval, a quantitative model for adjusting the corresponding process parameters of the remaining processing steps is constructed and trained.

[0110] The first processing quality index data in the initial processing stage and the real-time process parameters of the remaining processing stages are obtained and input into the trained quantization model, and the influence coefficients on the remaining processing stages are output.
