In traditional production, formula adjustments lack a process formula as a reference, relying mainly on operators to make simple adjustments to the original production formula based on particle purity and past experience. This method makes it difficult to achieve precise matching and dynamic optimization of formula parameters, easily leading to poor stability of the production formula, which in turn affects the consistency of carbon product production and fails to meet the requirements of high-precision production.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0023] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0024] It should also be noted that the division of multiple embodiments in this invention is only for the convenience of description and should not constitute a special limitation. Features in various embodiments can be combined and referenced in each other without contradiction.
[0025] Carbon products, such as crucibles and prebaked anodes, often have specific requirements for density and mechanical strength in their applications. To achieve high density, low porosity, and high mechanical strength, carbon and graphite products use a blend of particles with different size ranges in specific proportions, rather than using only one type of particle. For example, a carbon company might produce particles with size ranges of 2-4mm, 1-2mm, 0.5-1mm, 0.075-0.5mm, and 0-0.075mm. A particle size hopper is used to store particles within that size range, and the number of hoppers equals the number of size ranges. For instance, a hopper storing particles with a size range of 2-4mm is called a 2-4mm particle size hopper, and a hopper storing particles with a size range of 1-2mm is called a 1-2mm particle size hopper.
[0026] In related technologies, carbon product manufacturing formulas are adjusted based on particle purity and experience. This method has the following problems: particle purity only indicates the proportion of particles within a specific particle size range within a given particle size hopper, but it cannot specify the proportion of particles in other particle size ranges within the same hopper. Adjusting the formula based on purity and experience lacks specific and accurate values, making it difficult to guarantee production stability. Furthermore, exchanges of production formulas within the industry are affected by differences in equipment selection and production processes among companies. Often, a formula that performs well in one company may not work well in other companies, which to some extent creates difficulties in technical communication regarding production formulas among different companies.
[0027] Based on this, refer to Figure 1 As shown, this embodiment of the invention provides a method for adjusting the production formula of carbon products, including: S10. Obtain initial particle size distribution data from multiple particle size hoppers. The initial particle size distribution data includes the particle content information of each particle size range in each particle size hopper under the first scenario.
[0028] In one embodiment, the carbon product is produced by dividing the particles into five particle size ranges, namely 2-4mm, 1-2mm, 0.5-1mm, 0.075-0.5mm, and 0-0.075mm, which are named in descending order as the first particle size range (2-4mm), the second particle size range (1-2mm), the third particle size range (0.5-1mm), the fourth particle size range (0.075-0.5mm), and the fifth particle size range (0-0.075mm). Similarly, the hoppers corresponding to the storage of the above-mentioned multiple particle size ranges are named the first particle size hopper (storing particles with a particle size of 2-4 mm), the second particle size hopper (storing particles with a particle size of 1-2 mm), the third particle size hopper (storing particles with a particle size of 0.5-1 mm), the fourth particle size hopper (storing particles with a particle size of 0.075-0.5 mm), and the fifth particle size hopper (storing particles with a particle size of 0-0.075 mm). The carbon product production equipment includes a screening device. The particles used to prepare carbon products are screened and graded according to particle size using this screening device, and the particles of different particle size ranges after grading are respectively transported and stored in the corresponding multiple particle size hoppers.
[0029] In the first scenario, particles in each particle size bin are sieved using a standard full-size sieve to obtain initial particle size distribution data. This first scenario represents normal production conditions, where the produced carbon products exhibit high density, low porosity, and high mechanical strength, meeting both process and performance standards. Content information can be, for example, particle mass, mass fraction, or mass percentage. The standard full-size sieve is a complete set of standard sieving devices covering the entire particle size range and arranged continuously from largest to smallest aperture. It is used to sieve particles across all particle size ranges to obtain complete initial particle size distribution data. For example, the standard full-size sieve covers the five particle size ranges mentioned in the above embodiment (2-4mm, 1-2mm, 0.5-1mm, 0.075-0.5mm, 0-0.075mm). For example, the first particle size distribution bin is sieved using a standard full-screen sieve to obtain particle content information for the 2-4mm, 1-2mm, 0.5-1mm, 0.075-0.5mm, and 0-0.075mm particle size ranges. This represents the particle content information for each particle size range within the first particle size distribution bin. Similarly, the remaining bins are sieved using a standard full-screen sieve to obtain particle content information for each particle size range in the second, third, fourth, and fifth particle size distribution bins. This yields the initial particle size distribution data.
[0030] It should be noted that standard full-screen sieving is a sampling sieving method. It involves sampling particles after they have passed through the sieving equipment and performing full-size particle size sieving on the samples. Sampling must comply with the requirements of GB / T 47100-2026 standard, employing multi-point, equal-quantity, and random sampling to ensure that the samples taken represent the overall particle size distribution within the corresponding hopper. For example, samples are taken from the particles stored in each particle size hopper, and then the samples from each hopper are sequentially sieved using a standard full-screen sieve to obtain particle size distribution data for each particle size hopper.
[0031] S20. Determine the process formula based on the initial particle size distribution data and the initial production formula. The initial production formula includes the particle quantity of each particle size hopper in the first scenario. The process formula includes the theoretical particle quantity of each particle size hopper. The theoretical particle quantity is the particle quantity of the particle size hopper when all the particles stored in the particle size hopper are particles within the corresponding particle size range.
[0032] The initial production formula, under the first scenario (i.e., normal and stable production), is a production formula that includes the actual amount of particles used in each particle size hopper to prepare carbon products that meet the requirements of high density, low porosity, and high mechanical strength. In one embodiment, the initial production formula includes the particle amounts of the first, second, third, fourth, and fifth particle size hoppers. The process formula is the particle amount required for a particle size hopper under ideal conditions, assuming that all particles stored in a certain particle size hopper are pure particles within the corresponding particle size range of that hopper, without any deviation from the corresponding particle size range such as particle size exceeding the standard, mixing, or fine powder entrainment. In this case, it represents the amount of particles required in that particle size hopper to achieve the target product performance. For example, in the process formulation, if the particle size range corresponding to the first particle size baffle is 2-4mm, then the particle size range of all particles in the first particle size baffle is 2-4mm.
[0033] By constructing a realistic and ideal batching benchmark based on initial particle size distribution data and initial production formula, and using the actual particle size distribution obtained from testing as a basis, the actual production formula is corrected to the ideal process formula. This eliminates batching errors caused by non-ideal factors such as particle mixing and particle size deviation within the silos, providing an accurate and unified benchmark for batching control. Simultaneously, it accurately reflects the true proportioning requirements of particles in each particle size silo within the pure and standard particle size range, avoiding inaccurate batching due to raw material particle size fluctuations. This stabilizes the density, porosity, and mechanical strength of carbon products, improving product consistency and yield.
[0034] Specifically, in some embodiments, the theoretical particle usage of the particle size hopper corresponding to the target particle size range is determined based on the particle content information of the target particle size range in each of the particle size hoppers in the first case and the particle usage of each of the multiple particle size hoppers in the first case.
[0035] For example, if the target particle size range is 2-4mm, in the first scenario, the particle content information of the target particle size range in each particle size hopper includes the particle content information of the 2-4mm particle size range in the first particle size hopper, the particle content information of the 2-4mm particle size range in the second particle size hopper, the particle content information of the 2-4mm particle size range in the third particle size hopper, the particle content information of the 2-4mm particle size range in the fourth particle size hopper, and the particle content information of the 2-4mm particle size range in the fifth particle size hopper; in the first scenario, the particle usage of each particle size hopper in multiple particle size hoppers includes the particle usage of the first particle size hopper, the particle usage of the second particle size hopper, the particle usage of the third particle size hopper, the particle usage of the fourth particle size hopper, and the particle usage of the fifth particle size hopper.
[0036] The theoretical particle quantity of the target particle size range is determined by multiplying the particle content information of the 2-4mm particle size range in the first particle size range by the particle quantity of the first particle size range, the particle content information of the 2-4mm particle size range in the second particle size range by the particle quantity of the second particle size range, the particle content information of the 2-4mm particle size range in the third particle size range by the particle quantity of the third particle size range, the particle content information of the 2-4mm particle size range in the fourth particle size range by the particle quantity of the fourth particle size range, and the particle content information of the 2-4mm particle size range in the fifth particle size range by the particle quantity of the fifth particle size range.
[0037] In some embodiments, the process formulation is determined according to the following formula:
[0038] Among them, the The initial particle size distribution data information; The initial production formula; The process formulation is described above.
[0039] The initial particle size distribution data is an N x N matrix, where N is a positive integer. The element in the i-th row and j-th column of the initial particle size distribution data is the content of particles in the i-th particle size range within the j-th particle size hopper in the first scenario, where i and j are positive integers. The initial particle size distribution data can be denoted as, for example, as... , It can be represented as For example, It can be represented as , This represents the content of particles in the first particle size range in the fifth particle size bin under the first scenario, that is, the content of particles in the 2-4mm particle size range in the bin where the particle size is 0-0.075mm under the first scenario.
[0040] The initial production formula is an N x 1 matrix. The element in the i-th row of the initial production formula is the particle quantity of the i-th particle size hopper in the first scenario. For example, the initial production formula can be denoted as... , It can be represented as For example, It can be represented as , This represents the particle usage in the third particle size bin under the first scenario, i.e., the particle usage in the bin with a particle size of 0.5-1mm under the first scenario.
[0041] The process formulation is an N x 1 matrix, where the element value in the i-th row is the theoretical particle quantity for the i-th particle size hopper. For example, the process formulation is denoted as... , It can be represented as For example, It can be represented as , This represents the theoretical particle usage of the second particle size hopper, i.e., the theoretical particle usage in the hopper where the particle size is 1-2mm.
[0042] For example, It can be represented as , Right now
[0043]
[0044] By constructing the initial particle size distribution data, initial production formula, and process formula into a matrix and establishing mathematical relationships, a quantitative correlation between particle size distribution and formula dosage can be achieved. This standardizes and quantifies the formula calculation process, which helps improve the efficiency and accuracy of formula determination. It also facilitates automated and intelligent material adjustment and precise compensation in subsequent production processes, further enhancing the stability and reliability of carbon product production control.
[0045] S30. Determine the target production formula based on the process formula. The target production formula includes the current particle quantity for each particle size hopper. The current particle quantity is the particle quantity for each particle size hopper under the current target conditions.
[0046] The target production formula is the final execution formula that can be directly used for actual production batching, determined by calculation and correction based on the process formula determined in the first case under the current actual production situation, combined with the current particle size distribution and changes in production conditions.
[0047] Specifically, the current particle size distribution data of multiple particle size hoppers is obtained. The current particle size distribution data includes the content of particles in each particle size range within each particle size hopper under the current target conditions.
[0048] In the current target scenario, the particles in each particle size hopper are sieved using the same standard full-screen sampling and sieving method as in the first scenario to obtain the current particle size distribution data. For example, the current particle size distribution data includes, in the current target scenario, the particle content of the first particle size interval, the particle content of the second particle size interval, the particle content of the third particle size interval, the particle content of the fourth particle size interval, and the particle content of the fifth particle size interval in the first particle size hopper; similarly, the particle content of each particle size interval in the remaining particle size hoppers can be obtained.
[0049] It should be noted that the current particle size distribution data and the initial particle size distribution data under the first scenario are obtained in the same way, with the same testing methods, testing objects, and screening standards. Both are obtained through sampling and screening using a standard full-screen sieve, and both contain information on the content of particles in each particle size range within each silo. The only difference is that the initial particle size distribution data is obtained under the first scenario (i.e., production conditions with stable processes and excellent product performance), and is used to establish the process formulation as a benchmark; while the current particle size distribution data is obtained in the subsequent actual production process, under the current target scenario, and is used to determine the target production formulation suitable for the current production state in conjunction with the process formulation.
[0050] Furthermore, the target production formula is determined based on the process formulation and the current particle size distribution data. It should be noted that there are many methods for solving the target production formula based on the linear matrix relationship constructed from the initial particle size distribution data, the initial production formula, and the process formulation; only one embodiment is presented here.
[0051] In one embodiment, the target production formula is determined according to the following formula:
[0052] Among them, the The current particle size distribution data information; The inverse matrix of the current particle size distribution data information; The target production formula; The process formulation is described above.
[0053] The current particle size distribution data is an N x N matrix, where N is a positive integer. The element in the i-th row and j-th column of the current particle size distribution data represents the content of particles in the i-th particle size range within the j-th particle size hopper under the current target conditions, where i and j are positive integers. For example, the current particle size distribution data can be denoted as... , It can be represented as For example, It can be represented as , This represents the content of particles in the second particle size range within the first particle size hopper under the current target conditions, i.e., the content of particles in the 1-2mm particle size range within the hopper storing particles with a particle size of 2-4mm under the current target conditions.
[0054] The target production formula is an N x 1 matrix, where the element in the i-th row represents the current particle quantity in the i-th particle size hopper. For example, the target production formula can be denoted as... , It can be represented as For example, It can be represented as , This represents the current particle usage in the fourth particle size bin, specifically the current particle usage in the bin containing particles with a particle size of 0.075-0.5mm.
[0055] The process formulation is an N x 1 matrix, where the element value in the i-th row is the theoretical particle quantity for the i-th particle size hopper. The matrix construction of the process formulation has been described above and will not be repeated here.
[0056] For example, It can be represented as The solution method is based on existing technology and common knowledge, and will not be elaborated further here.
[0057] The process formulation is an ideal batching benchmark established based on the initial particle size distribution data under the first scenario. It reflects the optimal dosage when the particles in each particle size bin are of pure nominal size. By matching and calculating the process formulation with the current particle size distribution data, the deviation of the actual particle size distribution in each bin can be compensated and corrected. This determines the target production formulation suitable for the current target scenario, ensuring that even if the particle size fluctuates, the overall proportion and combination distribution of the final batched particles remain consistent with that under the first scenario. This ensures that carbon products consistently and stably meet the performance requirements of higher density, lower porosity, and higher mechanical strength.
[0058] Specifically, the intermediate production formula is determined based on the process formulation and current particle size distribution data. The intermediate production formula includes the calculated particle usage for each particle size hopper in the current target application, calculated from multiple particle size hoppers.
[0059] This calculated particle usage is an intermediate calculation based on the process formula and the actual particle size distribution of each silo. It is used to complete intermediate calculations such as particle size fluctuation compensation and ratio correction before determining the final, directly executable target production formula. This ensures that the final particle ratio matches the ideal ratio in the first scenario, improving the accuracy and rationality of the batching calculation. For example, the intermediate production formula includes the calculated particle usage for the first, second, third, fourth, and fifth particle size silos.
[0060] The total calculated particle usage in the intermediate production formula is compared with the total theoretical particle usage in the process formula. The total calculated particle usage in the intermediate production formula is, for example, the sum of the calculated particle usages for the first, second, third, fourth, and fifth particle size hoppers; the total theoretical particle usage in the process formula is, for example, the sum of the theoretical particle usages for the first, second, third, fourth, and fifth particle size hoppers.
[0061] Since the particles used in the entire production process are composed entirely of particles of various particle sizes, and the sum of the amounts of particles of all particle sizes is always 100%, this constraint condition needs to be added to constrain and correct the intermediate production formula calculation results.
[0062] When the comparison results are equal, the intermediate production formula is taken as the target production formula.
[0063] When the comparison results are not equal, the target production formula is determined by adjusting the total calculated particle amount in the intermediate production formula, the total theoretical particle amount in the process formula, and the calculated particle amount in the target particle size hopper in the intermediate production formula.
[0064] Specifically, the current particle quantity of the target particle size hopper is the calculated particle quantity of the target particle size hopper in the intermediate production formula multiplied by the first total quantity and divided by the second total quantity; the first total quantity is the sum of all theoretical particle quantities in the process formula; and the second total quantity is the sum of all calculated particle quantities in the intermediate production formula.
[0065] For example, the process formulation includes a theoretical particle amount of 212.07 kg for the first particle size hopper, a theoretical particle amount of 493.94 kg for the second particle size hopper, a theoretical particle amount of 349.23 kg for the third particle size hopper, a theoretical particle amount of 441.23 kg for the fourth particle size hopper, a theoretical particle amount of 568.53 kg for the fifth particle size hopper, and a total particle amount of 2065 kg in the process formulation; The calculated particle usage of the intermediate production formula, including the first particle size hopper (709.81 kg), the second particle size hopper (142.35 kg), the third particle size hopper (314.15 kg), the fourth particle size hopper (159.91 kg), the fifth particle size hopper (739.63 kg), and the total particle usage of the intermediate production formula, is 2065.85 kg.
[0066] The total particle usage in the intermediate production formula is not equal to the total particle usage in the process formula. The current particle usage in the first particle size bin is the calculated particle usage in the first particle size bin multiplied by the total particle usage in the process formula, divided by the total particle usage in the intermediate production formula. The current particle usage in the first particle size hopper is 709.52 kg; the current particle usage in the second particle size hopper is calculated by multiplying the calculated particle usage of the second particle size hopper by the sum of the particle usage in the process formula, and then dividing by the sum of the particle usage in the intermediate production formula. The current particle usage in the second particle size hopper is 142.29 kg; the current particle usage in the third particle size hopper is calculated by multiplying the calculated particle usage of the third particle size hopper by the sum of the particle usage in the process formula, and then dividing by the sum of the particle usage in the intermediate production formula. The current particle usage in the third particle size hopper is 314.02 kg; the current particle usage in the fourth particle size hopper is calculated by multiplying the calculated particle usage in the fourth particle size hopper by the sum of the particle usage in the process formula, and then dividing by the sum of the particle usage in the intermediate production formula. The current particle usage in the fourth particle size hopper is 159.84 kg; the current particle usage in the fifth particle size hopper is calculated by multiplying the calculated particle usage of the fifth particle size hopper by the sum of the particle usage in the process formula, and then dividing by the sum of the particle usage in the intermediate production formula. The current particle quantity in the 5th particle size hopper is 739.32 kg. In summary, the target production formula includes the following particle quantities: 709.52 kg in the 1st particle size hopper, 142.29 kg in the 2nd particle size hopper, 314.02 kg in the 3rd particle size hopper, 159.84 kg in the 4th particle size hopper, and 739.32 kg in the 5th particle size hopper.
[0067] By using the above adjustment methods, the total amount of each particle size range in the target production formula is kept consistent with the total amount in the process formula, ensuring that the amount of particles formed by the final batching is stably matched with the theoretical amount of particles, thereby improving the quality stability and reliability of carbon products.
[0068] The following detailed description of the carbon product production formula adjustment method of this application is provided through specific embodiments.
[0069] Example 1 In carbon product manufacturing enterprises, particle size ranges are divided into 2-4mm, 1-2mm, 0.5-1mm, 0.075-0.5mm, and 0-0.075mm.
[0070] Company A's initial production formula under the first scenario, i.e., normal production conditions, is shown in Table 1; after executing step S10, the initial particle size distribution data under the first scenario, i.e., normal production conditions, is shown in Table 2: Table 1 Initial Production Formula of Company A
[0071] Table 2 Initial Particle Size Distribution Data for Company A
[0072] After a period of normal production, Company A experienced a deviation in screening due to a failure to adjust the screening equipment in a timely manner or to detect equipment damage in a timely manner. The screening results changed significantly, and the carbon products produced according to the initial production formula did not meet the process and performance requirements. In order to ensure the quality of subsequent carbon products, the initial production formula needs to be adjusted and improved through this adjustment method, that is, the target production formula needs to be determined.
[0073] Execute step S20 to determine the process formulation based on the initial particle size distribution data and the initial production formulation; The initial particle size distribution data is denoted as B, and B can be represented as The initial production formula is denoted as X, and X can be represented as... Then according to the formula The process formula was determined, as shown in Table 3.
[0074] Table 3. Process Formula Table for Company A
[0075] The current particle size distribution data of multiple particle size bins are obtained, as shown in Table 4; Table 4. Current Particle Size Distribution Data of Company A
[0076] As shown in Tables 2 and 4, the content of particles in the 2-4mm particle size range in the 2-4mm particle size hopper changed from 73.38% to 29.56%. In order to ensure production quality, the initial production formula needs to be adjusted and improved.
[0077] The target production formula is determined based on the process formulation and current particle size distribution data.
[0078] The process formula is denoted as Y, and Y can be represented as: The current particle size distribution data is denoted as... , It can be represented as According to the formula The target production formula was determined, as shown in Table 5.
[0079] Table 5. Target Production Formula of Company A
[0080] As shown in Tables 1-5, the 2-4mm particle size hopper contains particles in the 1-2mm particle size range. In the adjusted target production formula, the amount of 2-4mm particle size hopper is increased, and the amount of 1-2mm particle size hopper is reduced. The particles in the 1-2mm particle size range in the 2-4mm particle size hopper are used to fill the particle size required for the process, and the remaining hoppers are finely adjusted.
[0081] Example 2 The particle size ranges for carbon product manufacturers A and B are 2-4mm, 1-2mm, 0.5-1mm, 0.075-0.5mm, and 0-0.075mm.
[0082] Company A learns from Company B, a peer company, which provides technical support. Company B provides its initial production formula and initial particle size distribution data, leading to the determination of Company B's process formula, as shown in Table 6. It should be noted that the method for determining Company B's process formula is the same as that for Company A, and will not be elaborated further here. Because the two companies use different screening equipment, Company A's screening equipment achieves higher particle purity. Therefore, to fully realize the process formula provided by Company B, Company A's initial production formula needs to be fine-tuned.

[0084] Obtain the current particle size distribution data of multiple particle size bins of Company A, as shown in Table 7; and determine the target production formula of Company A based on the process formula of Company B and the current particle size distribution data of Company A.
[0085] Table 7. Current Particle Size Distribution Data of Company A
[0086] At this point, Company B's process formula Y can be expressed as: Company A's current particle size distribution data is denoted as... , It can be represented as According to the formula The target production formula for Company A was determined, as shown in Table 8.
[0087] Table 8. Target Production Formula of Company A
[0088] In summary, as demonstrated in Examples 1 and 2, acquiring particle size distribution data not only determines the proportion of particles in a corresponding particle size range within the silo but also reflects the true content of particles in other particle size ranges within the silo. This solves the problem in related technologies where relying solely on particle purity cannot fully grasp the particle size composition. Furthermore, establishing a quantitative relationship between initial particle size distribution data, initial production formula, and process formula through matrix operations provides specific and accurate numerical basis for formula adjustments, eliminating reliance on empirical judgments in related technologies and effectively improving the stability and reliability of the production process. Moreover, using a unified process formula as a benchmark eliminates the impact of differences in equipment selection and production processes among different enterprises, making the production formula universal and portable. This effectively reduces the difficulty of formula technology exchange between enterprises and facilitates the efficient sharing and widespread application of formula resources.
