[0051] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0052] The core of this application is to provide a method, device, equipment and medium for setting the aluminum output indication amount.

[0053] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0054] Figure 1 This is a flow chart of a method for setting the aluminum output indication amount provided in an embodiment of the present application. Figure 1 As shown, the method includes:

[0055] S10: Obtain the process parameters set by the slot control machine.

[0056] Among them, the process parameters at least include bath temperature, aluminum level, electrolyte level, set voltage, molecular ratio, aluminum oxide feed amount, aluminum fluoride feed amount and current intensity.

[0057] It is understandable that in modern large-scale industrial electrolytic aluminum production, a slot control machine is generally used to adjust process parameters. In order to set the aluminum output indication amount, it is necessary to comprehensively consider the other process parameters in the electrolytic aluminum production. Therefore, in this embodiment, in order to set the aluminum output indication amount of the electrolytic aluminum production on the same day, the process parameters set by the slot control machine on the same day are first obtained.

[0058] Specifically, the process parameters should at least include bath temperature, aluminum level, electrolyte level, set voltage, molecular ratio, aluminum oxide feed rate, aluminum fluoride feed rate and current intensity, and may also include other parameters depending on the specific implementation situation.

[0059] S11: Obtain the type of electrolytic cell corresponding to the cell control machine, and obtain the corresponding process parameter comparison table.

[0060] The process parameter comparison table includes the current efficiency corresponding to different process parameters in the electrolytic cell under the type of electrolytic cell.

[0061] Furthermore, the type of electrolytic cell corresponding to the cell control machine is obtained. It is understandable that the process parameters of the electrolytic cell continue to change since it is put into use. Therefore, the electrolytic cell can be classified according to the process parameters in the electrolytic cell to obtain a variety of electrolytic cell types, and then the aluminum output indication of the corresponding cell control machine is set according to the type of electrolytic cell, so that the setting of the aluminum output indication is more reasonable.

[0062] As a preferred embodiment, the types of electrolytic cells are divided into four categories in this embodiment: climbing cells, cells with abnormal iron-silicon content, cells with severe cathode voltage drop, and normal cells. In order to obtain the type of electrolytic cell, it is necessary to first obtain the stable production period of the electrolytic cell. The stable production period represents the period when the electrolytic cell is in stable electrolytic aluminum production. In this embodiment, there is no restriction on the method of obtaining the stable production period, which depends on the specific implementation situation. Further determine whether the electrolytic cell is in a stable production period. If the electrolytic cell is not in a stable production period, the type of the electrolytic cell is a climbing cell. If the electrolytic cell is in a stable production period, observe the two process parameters of iron content and silicon content in the electrolytic cell; determine whether the iron content and silicon content of the electrolytic cell meet the first preset condition; if the iron content and silicon content of the electrolytic cell meet the first preset condition, the type of the electrolytic cell is an abnormal iron-silicon content cell.

[0063] It should be noted that, in this embodiment, there is no restriction on the first preset condition, and the iron content and the silicon content can be set to meet a preset value respectively, and the ratio of the iron content to the silicon content can also be set to a preset ratio, depending on the specific implementation situation. Furthermore, if the iron content and the silicon content of the electrolytic cell do not meet the first preset condition, it is determined whether the cathode voltage drop of the electrolytic cell meets the second preset condition; if the cathode voltage drop of the electrolytic cell meets the second preset condition, the type of the electrolytic cell is a cathode voltage drop severe cell; if the cathode voltage drop of the electrolytic cell does not meet the second preset condition, the type of the electrolytic cell is a normal cell. In this embodiment, there is no restriction on the second preset condition, and the cathode voltage drop can be set to meet a preset value, depending on the specific implementation situation. It is worth noting that the above acquisition of the electrolytic cell type must be carried out in the order of climbing cell, abnormal iron-silicon content cell, severe cathode voltage drop cell to normal cell.

[0064] Furthermore, after obtaining the type of electrolytic cell, it is also necessary to obtain the process parameter comparison table corresponding to the electrolytic cell. The process parameter comparison table contains the current efficiency corresponding to different process parameters in the electrolytic cell under the type of electrolytic cell. Therefore, the above four types of electrolytic cells each correspond to a process parameter comparison table as a reference for their respective process specifications.

[0065] As a preferred embodiment, after the type of electrolytic cell is determined, a daily report of process parameters of the cell controller of the electrolytic cell is obtained. The daily report of process parameters includes the process parameters of the cell controller within a preset date, and the process parameters at least include current efficiency, cell temperature, aluminum level, electrolyte level, set voltage, molecular ratio, aluminum oxide feed amount, aluminum fluoride feed amount, current intensity, iron content, silicon content and cathode voltage drop. In this embodiment, there is no restriction on the preset date. In the specific implementation, the daily report of process parameters can record the process parameters of the past 6 months, depending on the specific implementation situation.

[0066] It is understandable that due to actual production process adjustments or settings, some process parameters may have null values ​​in the process parameter daily report. In order to better generate a process parameter comparison table, it is necessary to further fill in the null values ​​of the process parameters in the process parameter daily report. Specifically, for the null value of a certain process parameter on a certain day, you can select an empirical value as the filler, or you can use the non-null value to trace back in chronological order as the filler; that is, for the null value of a certain parameter on a certain day, first trace back the most recent non-null value of the parameter in chronological order as the filler; if all the values ​​traced back are null values, then trace back the most recent non-null value of the parameter in chronological order as the filler. In this embodiment, the specific method of filling the null values ​​of the process parameters is not limited, and it depends on the specific implementation situation.

[0067] Finally, based on the daily report of process parameters, the mean values ​​of the corresponding remaining process parameters under different current efficiencies are obtained in sequence with preset accuracy to generate a process parameter comparison table for the electrolytic cell. In this embodiment, there is no restriction on the preset accuracy. Preferably, the preset accuracy can be 0.5%, that is, in the specific implementation, according to a current efficiency gear of 0.5%, based on the process parameters in the daily report of process parameters, the mean values ​​of the remaining process parameters under each current efficiency gear are obtained from 0% to 100%, thereby generating a process parameter comparison table for the electrolytic cell. The process parameter comparison table of the electrolytic cell specifically includes the mean values ​​of the corresponding process parameters under each current efficiency gear.

[0068] S12: Obtain an estimated value of the current efficiency of the slot control machine according to the process parameters and the process parameter comparison table.

[0069] Furthermore, after obtaining the process parameter comparison table, the current efficiency estimation value of the cell controller is obtained in combination with the obtained process parameters. Since the process parameter comparison table of the electrolytic cell specifically includes the mean values ​​of each process parameter corresponding to each current efficiency level, the current efficiency of the daily cell can be estimated by the optimal similarity algorithm.

[0070] The optimal similarity algorithm is an algorithm that measures similarity by calculating the Euclidean distance between two high-dimensional vectors. The calculation method is as follows:

[0071]

[0072] in, express and The distance between The smaller the distance, the more similar the two vectors are. This method calculates the similarity between the process parameters of the electrolytic cell and the process parameters under each current efficiency in the process parameter comparison table of the electrolytic cell, and finds the most similar one (i.e. the one with the smallest distance) as the estimated current efficiency of the electrolytic cell on that day.

[0073] S13: Obtaining the aluminum output indication amount of the slot control machine according to the current efficiency estimation value and the current intensity, so that the slot control machine can set the aluminum output indication amount.

[0074] It can be understood that the actual aluminum output is the quotient of the theoretical aluminum output and the current efficiency. The theoretical aluminum output can be expressed as the product of the electrochemical equivalent of aluminum, the current intensity and the time. Therefore, the following relationship exists:

[0075]

[0076] in, I is the current intensity, t is the time (the electrolytic aluminum production time on that day: 24 hours), η is the current efficiency, TAP is the actual aluminum output (i.e., the aluminum output indication), and is the electrochemical equivalent of aluminum. Through the above formula, the aluminum output indication of the slot control machine is obtained according to the current efficiency estimation value and the current intensity, so that the slot control machine can set the aluminum output indication.

[0077] In this embodiment, by obtaining the process parameters set by the cell control machine; wherein the process parameters at least include cell temperature, aluminum level, electrolyte level, set voltage, molecular ratio, alumina feed amount, aluminum fluoride feed amount and current intensity; obtaining the type of electrolytic cell corresponding to the cell control machine, and obtaining the corresponding process parameter comparison table; wherein the process parameter comparison table contains the current efficiency corresponding to different process parameters in the electrolytic cell under the type of electrolytic cell; obtaining the estimated value of the current efficiency of the cell control machine according to the process parameters and the process parameter comparison table; obtaining the aluminum output indication of the cell control machine according to the estimated value of the current efficiency and the current intensity, so that the cell control machine can set the aluminum output indication. It can be seen that the above scheme is to classify the electrolytic cells and form a process parameter comparison table of current efficiency for each type of electrolytic cell as a reference. In actual production, the process parameters are matched with the process parameter comparison table of the corresponding electrolytic cell classification, so as to estimate the current efficiency of its production on that day, and then obtain the recommendation of the aluminum output indication, so that the setting of the aluminum output indication is more accurate and intelligent, and can be free from the limitations of human experience, and is suitable for large-scale promotion.

[0078] The above embodiment does not limit the method for obtaining the stable production period of the electrolytic cell. As a preferred embodiment, this is limited in this embodiment. In this embodiment, obtaining the stable production period of the electrolytic cell includes:

[0079] Obtain the standard deviation of the molecular ratio, the standard deviation of the cell temperature, the standard deviation of the set voltage and the standard deviation of the current efficiency of the electrolytic cell within a natural month starting from the start-up period;

[0080] Determine whether each standard deviation is less than a first threshold;

[0081] If yes, the stable production period will start from the first day of the next month of the current natural month.

[0082] It is understandable that the start-up period is the date when the electrolytic cell is put into production. Starting from the start-up period, the standard deviation of the molecular ratio in the electrolytic cell, the standard deviation of the cell temperature, the standard deviation of the set voltage, and the standard deviation of the current efficiency are obtained in each natural month until it is determined that the standard deviations of the four process parameters are all less than the first threshold.

[0083] In this embodiment, there is no restriction on the first threshold value, which is determined according to the specific implementation situation. Preferably, the first threshold value can be set to 1.1, that is, the standard deviation of the molecular ratio, the standard deviation of the cell temperature, the standard deviation of the set voltage, and the standard deviation of the current efficiency are all less than 1.1. At this time, the first day of the next month of the current natural month is taken as the first day of the stable production period, that is, before that day, it is the climbing period, and the electrolytic cell is a climbing cell; the first day of the next month of the current natural month is the stable production period, and the electrolytic cell is not a climbing cell during the stable production period.

[0084] In this embodiment, by obtaining the stable production period of the electrolytic cell, it is possible to determine whether the electrolytic cell is a climbing cell.

[0085] Further, as a preferred embodiment, judging whether the iron content and silicon content of the electrolytic cell meet the first preset condition specifically includes:

[0086] If the iron content and silicon content of the electrolytic cell on the current day are respectively greater than the iron content and silicon content of the previous day within a continuous preset number of days, and / or the sum of the iron content and silicon content in the electrolytic cell is not less than the second threshold value, then the iron content and silicon content of the electrolytic cell meet the first preset condition;

[0087] Otherwise, the iron content and the silicon content of the electrolytic cell do not meet the first preset condition.

[0088] It is understandable that for motor slots that are not classified as climbing slots, the two process parameters of iron content and silicon content are observed. Specifically, if the iron content and silicon content of the electrolytic cell on the same day are respectively greater than the iron content and silicon content of the previous day within a consecutive preset number of days, and / or the sum of the iron content and silicon content in the electrolytic cell is not less than the second threshold, then the iron content and silicon content of the electrolytic cell meet the first preset condition, that is, if one of the above two conditions is met, the iron content and silicon content of the electrolytic cell meet the first preset condition.

[0089] It should be noted that, in this embodiment, there is no restriction on the preset number of days, which depends on the specific implementation situation. Preferably, the iron content and silicon content of the day can be set to be greater than the previous day's value for three consecutive days. In addition, in this embodiment, there is no restriction on the second threshold, which depends on the specific implementation situation. Preferably, the sum of the iron content and the silicon content in the electrolytic cell can be set to be not less than 0.2%.

[0090] Further, as a preferred embodiment, if the iron content and the silicon content of the electrolytic cell do not meet the first preset condition, determining whether the cathode voltage drop of the electrolytic cell meets the second preset condition specifically includes:

[0091] If the cathode voltage drop of the electrolytic cell is not less than the third threshold value, and / or the cathode voltage drop of the electrolytic cell is not less than a preset multiple of the minimum voltage drop when the electrolytic cell is in a normal cell, then the cathode voltage drop of the electrolytic cell meets the second preset condition;

[0092] Otherwise, the cathode voltage drop of the electrolytic cell does not meet the second preset condition.

[0093] For the electrolytic cells that are not classified as climbing cells and cells with abnormal iron and silicon content, the cathode voltage drop in the electrolytic cell is further checked. Specifically, if the cathode voltage drop of the electrolytic cell is not less than the third threshold value, and / or the cathode voltage drop of the electrolytic cell is not less than the preset multiple of the minimum voltage drop when the electrolytic cell is in a normal cell, the cathode voltage drop of the electrolytic cell meets the second preset condition; that is, if one of the above two conditions is met, the cathode voltage drop of the electrolytic cell meets the second preset condition.

[0094] In this embodiment, there is no restriction on the third threshold value, which is determined according to the specific implementation situation. Preferably, the cathode voltage drop can be specifically set to be not less than 300. In addition, there is no restriction on the preset multiple in this embodiment, which is determined according to the specific implementation situation. Preferably, the cathode voltage drop can be specifically set to be not less than 1.2 times the minimum voltage drop when the electrolytic cell is in a normal cell.

[0095] It should be noted that the minimum voltage drop of the electrolytic cell when it is in a normal state is not a known quantity and needs to be calculated through the historical data of the electrolytic cell: the minimum cathode voltage drop during the normal state is taken as the minimum voltage drop of the normal state. If the electrolytic cell does not have a normal state, this value is 0.

[0096] In this embodiment, by setting the first preset condition and the second preset condition, the determination of the cell with abnormal iron-silicon content, the cell with severe cathode voltage drop and the normal cell is achieved.

[0097] In order to better implement the recommendation and setting of the aluminum output indication, as a preferred embodiment, in the specific implementation, the process parameter comparison table can also be updated according to the preset period. That is, by setting a timed task, the data in the process parameter comparison table is updated at a preset period, so as to obtain the current efficiency estimation value more accurately, and then obtain the aluminum output indication more accurately. In this embodiment, there is no restriction on the preset period, which depends on the specific implementation situation. Preferably, the preset period can be set to one month.

[0098] In the above embodiments, the method for setting the aluminum output indication amount is described in detail, and the present application also provides an embodiment corresponding to the device for setting the aluminum output indication amount. It should be noted that the present application describes the embodiments of the device part from two perspectives, one is based on the perspective of the functional module, and the other is based on the perspective of the hardware structure.

[0099] Figure 2 This is a schematic diagram of a device for setting the aluminum output indication amount provided in an embodiment of the present application. Figure 2 As shown, the aluminum output indication amount setting device includes:

[0100] The first acquisition module 10 is used to acquire the process parameters set by the tank control machine; wherein the process parameters at least include tank temperature, aluminum level, electrolyte level, set voltage, molecular ratio, aluminum oxide feed amount, aluminum fluoride feed amount and current intensity;

[0101] The second acquisition module 11 is used to obtain the type of electrolytic cell corresponding to the cell control machine and obtain the corresponding process parameter comparison table; wherein the process parameter comparison table contains the current efficiency corresponding to different process parameters in the electrolytic cell under the type of electrolytic cell;

[0102] A third acquisition module 12 is used to obtain the current efficiency estimation value of the slot control machine according to the process parameters and the process parameter comparison table;

[0103] The fourth acquisition module 13 is used to obtain the aluminum output indication of the slot control machine according to the current efficiency estimation value and the current intensity, so that the slot control machine can set the aluminum output indication.

[0104] In this embodiment, the aluminum output indicator setting device includes a first acquisition module, a second acquisition module, a third acquisition module and a fourth acquisition module. By acquiring the process parameters set by the cell control machine; wherein the process parameters at least include cell temperature, aluminum level, electrolyte level, set voltage, molecular ratio, alumina feed amount, aluminum fluoride feed amount and current intensity; acquiring the type of electrolytic cell corresponding to the cell control machine, and acquiring the corresponding process parameter comparison table; wherein the process parameter comparison table contains the current efficiency corresponding to different process parameters in the electrolytic cell under the type of electrolytic cell; acquiring the current efficiency estimation value of the cell control machine according to the process parameters and the process parameter comparison table; acquiring the aluminum output indicator of the cell control machine according to the current efficiency estimation value and the current intensity, so that the cell control machine can set the aluminum output indicator. It can be seen that the above scheme classifies the electrolytic cells and forms a process parameter comparison table of current efficiency for each type of electrolytic cell as a reference. In actual production, the process parameters are matched with the process parameter comparison table of the corresponding electrolytic cell classification to estimate the current efficiency of its production on that day, and then the recommendation of the aluminum output indication amount is obtained, so that the setting of the aluminum output indication amount is more accurate and intelligent, free from the limitations of human experience, and suitable for large-scale promotion.
