Description

Technical Field

[0001] The present application belongs to the technical field of copper rod continuous casting and rolling, and in particular relates to a control method for a copper rod continuous casting and rolling production line. Background Art

[0002] The continuous casting and rolling technology of copper rod is a copper rod rolling process in which liquid copper is poured into a continuous casting machine to cast a copper billet (called a continuous casting billet). The billet is then kept warm in a soaking furnace for a certain period of time without cooling and then directly entered into a hot rolling mill to be rolled into shape. This clever combination of casting and rolling processes facilitates mechanization and automation.

[0003] In existing technology, adjusting copper rod production parameters often relies on operator experience and manual operation, which is not only inefficient but also difficult to ensure accurate and timely adjustments. When quality issues arise during production, operators may need to spend a considerable amount of time troubleshooting and making adjustments, resulting in production interruptions or reduced efficiency. Furthermore, due to process fluctuations, copper rods after continuous casting may have problems such as excessive oxygen content and surface defects; copper rods after continuous rolling may also exhibit dimensional deviations and other issues. These issues lead to unstable copper rod product quality, making it difficult to meet the needs of downstream customers. Therefore, the current problem of copper rod continuous casting and rolling is that the dynamic response of parameters is delayed, resulting in large quality fluctuations. Summary of the Invention

[0029] In the prior art, adjusting copper rod production parameters often relies on operator experience and manual manipulation, which is not only inefficient but also difficult to ensure accurate and timely adjustments. When quality issues arise during production, operators may need to spend a significant amount of time troubleshooting and making adjustments, leading to production interruptions or reduced efficiency. Furthermore, due to process fluctuations, copper rods after continuous casting may exhibit problems such as excessive oxygen content and surface defects; while copper rods after continuous rolling may exhibit dimensional deviations. These issues lead to unstable copper rod product quality, making it difficult to meet the needs of downstream customers. Consequently, the current problem of delayed dynamic parameter response during continuous casting and rolling of copper rods leads to significant quality fluctuations.

[0030] In order to solve the above problems, an embodiment of the present application provides a method for controlling a copper rod continuous casting and rolling production line. In this method, the specifications and real-time oxygen content of the copper rod are obtained; the continuous casting parameters are determined according to the specifications and the real-time oxygen content; the continuous casting parameters are adjusted according to the first quality data of the copper rod after continuous casting using the continuous casting parameters; the real-time thickness of the copper rod after continuous casting according to the adjusted continuous casting parameters is obtained; the rolling parameters are determined according to the real-time thickness; and the rolling parameters are adjusted according to the second quality data of the copper rod after continuous rolling using the rolling parameters. Therefore, the method for controlling a copper rod continuous casting and rolling production line provided by an embodiment of the present application can significantly improve the quality of the copper rod, reduce the generation of defects and substandard products, and help solve the problem of large quality fluctuations caused by the lag in the dynamic response of parameters during continuous casting and rolling of copper rods; it realizes closed-loop control of the continuous casting and rolling process, helps to optimize the production process, and improve production efficiency and stability; through real-time monitoring and adjustment, problems in the production process can be discovered and solved in a timely manner, reducing downtime and waste.

[0031] The copper rod continuous casting and rolling production line control method provided in the embodiment of the present application can be applied to the copper rod continuous casting and rolling production line control equipment. At this time, the copper rod continuous casting and rolling production line control equipment is the execution entity of the copper rod continuous casting and rolling production line control method provided in the embodiment of the present application. The embodiment of the present application does not impose any restrictions on the specific type of the copper rod continuous casting and rolling production line control equipment.

[0032] For example, the copper rod continuous casting and rolling production line control device can be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a mobile phone, a tablet computer, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), a desktop computer, a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a computer, a laptop computer, a handheld communication device, a handheld computing device, a satellite wireless device, etc., but is not limited to these.

[0033] In order to better understand the copper rod continuous casting and rolling production line control method provided in the embodiment of the present application, the specific implementation process of the copper rod continuous casting and rolling production line control method provided in the embodiment of the present application is exemplarily introduced below.

[0034] Figure 1 A schematic flow chart of a copper rod continuous casting and rolling production line control method provided in an embodiment of the present application is shown. The copper rod continuous casting and rolling production line control method includes: S100, obtains the specifications and real-time oxygen content of the copper rod.

[0035] For example, the copper rod diameter (e.g., φ8mm), length (e.g., 1000m), and brand (e.g., T2 copper) required by the order can be obtained through the human-machine interface (HMI), and the laser-induced breakdown spectroscopy (LIBS) online detector can be used to measure the oxygen content (e.g., 350ppm) of the copper liquid in the smelting furnace in real time.

[0036] S200, determines continuous casting parameters based on specifications and real-time oxygen content.

[0037] For example, a model (such as a multivariate regression model, a multilayer perceptron (MLP) neural network, a support vector machine model, etc.) can be established based on historical production data, the specifications and real-time oxygen content are input into the model, and the continuous casting parameters are output.

[0038] In one possible implementation, see Figure 2 , S200, specifications include composition, diameter and length, continuous casting parameters include continuous casting temperature, continuous casting speed, cooling speed and flow rate of protective gas, according to the specifications and real-time oxygen content to determine the continuous casting parameters, including: S210, determining the continuous casting temperature according to the composition.

[0039] For example, the relationship between composition and liquidus temperature can be determined based on the copper alloy phase diagram and thermodynamic database. For example, for T2 copper (purity ≥ 99.90%), the liquidus temperature is 1083°C; if it contains trace phosphorus (0.015%), the liquidus temperature is reduced to 1078°C (because phosphorus reduces the melting point by about 5°C / 0.01%), and the superheat range (such as 30~50°C) is set according to the composition. For example, the continuous casting temperature of T2 copper is T = T liquidus +ΔT superheat , where T liquidus is the liquidus temperature, ΔT superheat It's superheat.

[0040] S220, determining the continuous casting speed and cooling speed according to the diameter.

[0041] For example, the relationship between diameter, continuous casting speed and cooling speed can be determined by performing multiple regression analysis based on historical production data, and the continuous casting speed and cooling speed can be determined based on the diameter. 1= = , cooling rate v2= , where K, is the empirical coefficient, D is the diameter, and t is the solidification time.

[0042] S230: Determine the flow rate of the protective gas according to the real-time oxygen content.

[0043] For example, the relationship between the protective gas flow rate and the oxygen content can be established by linear regression fitting based on historical production data, and the protective gas flow rate can be determined based on the real-time oxygen content. For example, the protective gas flow rate Q = Q0 + β (C O −C O,目标 ), where Q0 is the basic flow, β is the empirical coefficient, and C O is the real-time oxygen content, C O,目标 is the target oxygen level.

[0044] Through steps S210 to S230, precise temperature control based on composition reduces fluctuations in the ingot's oxygen content and improves grain uniformity. Dynamic matching of diameter, casting speed, and cooling rate enables real-time linkage between the casting and cooling rates, improving yield. Dynamic adjustment of the shielding gas flow rate increases shielding gas utilization while reducing oxidation losses. Multi-parameter coupled control overcomes the limitations of traditional single-parameter adjustment.

[0045] S300: Adjust the continuous casting parameters according to first quality data of the copper rod after continuous casting using the continuous casting parameters, wherein the first quality data includes oxygen content and surface defects of the copper rod.

[0046] For example, the copper rod after continuous casting can be sampled and tested to obtain first quality data, including oxygen content (such as 380 ppm), surface crack length (such as 0.5 mm), and diameter deviation (such as +0.02 mm), and the continuous casting parameters can be adjusted according to the first quality data.

[0047] In one possible implementation, see Figure 2 S300, adjusting the continuous casting parameters according to the first quality data of the copper rod after continuous casting using the continuous casting parameters, including: S310: Determine a first adjustment target based on the first quality data, wherein the first adjustment target includes reducing oxygen content and / or reducing surface defects.

[0048] For example, data such as oxygen content deviation, length or area of surface defects can be converted into a standardized score (0 to 100 points) based on the first quality data, and the standardized score can be compared with a preset score threshold to determine the first adjustment target.

[0049] S320: Determine a first adjustment plan according to the first adjustment target, wherein the first adjustment plan includes adjustment conditions and adjustment direction.

[0050] For example, historical production data can be used to train a machine learning model (such as a decision tree or a neural network) to predict the impact of adjusting the continuous casting parameters on the first adjustment target, establish a mapping relationship table between the first adjustment target and the continuous casting parameters, and determine the first adjustment plan based on the mapping relationship table.

[0051] Optionally, see Figure 2 S320, determining a first adjustment plan according to the first adjustment target, including: S321: When the first adjustment target includes reducing the oxygen content, the adjustment direction in the first adjustment scheme includes reducing the continuous casting temperature and / or increasing the flow rate of the protective gas.

[0052] For example, when it is detected that the real-time oxygen content exceeds a target threshold (such as 50 ppm), the continuous casting temperature is reduced and / or the flow rate of the protective gas is increased.

[0053] S322: When the first adjustment target includes reducing surface defects, the adjustment direction in the first adjustment scheme includes adjusting the cooling speed and / or adjusting the continuous casting speed.

[0054] For example, when the first adjustment target includes reducing surface defects, the cooling rate (changing the secondary cooling water flow rate or air cooling intensity) or the continuous casting speed can be dynamically adjusted according to the defect type. For example, when it is detected that the surface crack area accounts for 2% (target ≤1%), the cooling rate is reduced (the water flow rate is reduced from 35m³ / h to 30m³ / h), and the continuous casting speed is reduced from 1.2m / min to 1.1m / min.

[0055] S323, when the continuous casting temperature needs to be lowered, the adjustment conditions include that the flow rate of the protective gas reaches a maximum value and the real-time oxygen content exceeds an oxygen content threshold.

[0056] For example, the continuous casting temperature may be lowered when the flow rate of the shielding gas reaches the maximum value and the real-time oxygen content exceeds the oxygen content threshold. For example, when the shielding gas flow rate is ≥ the maximum value (such as 60Nm³ / h) and the real-time oxygen content is > 50ppm and lasts for 10 minutes, the continuous casting temperature is reduced from 1200°C to 1180°C in two steps (10°C each time).

[0057] S324, when the cooling rate needs to be increased, the adjustment conditions include the occurrence of shrinkage cavities.

[0058] For example, when shrinkage cavities appear, the cooling rate is increased. For example, when shrinkage cavities (diameter > 2 mm) are detected inside the copper rod by X-ray, the cooling water flow rate is increased from 25 m³ / h to 35 m³ / h.

[0059] S325, when the cooling rate needs to be reduced, the adjustment condition includes that the area of the cracks in the copper rod after continuous casting exceeds a first area threshold.

[0060] For example, when the crack area of the copper rod after continuous casting exceeds a first area threshold (such as 1.5%), the cooling rate is reduced. For example, when the crack area is 2.0%>1.5%, the cooling water flow rate is reduced from 40 m³ / h to 30 m³ / h.

[0061] S326, when the continuous casting speed needs to be increased, the adjustment conditions include the surface roughness of the copper rod after continuous casting being greater than a first roughness threshold or a cold shut defect occurring.

[0062] For example, when the surface roughness of the copper rod after continuous casting is greater than the first roughness threshold or a cold shut defect occurs, the continuous casting speed is increased. For example, when the surface roughness is greater than Ra 6.3 μm or a cold shut occurs, the continuous casting speed is increased from 0.8 m / min to 0.9 m / min.

[0063] S327, in the case where the continuous casting speed needs to be reduced, the adjustment conditions include that the pull marks and wave-shaped defects of the copper rod after continuous casting exceed the second area threshold.

[0064] For example, when the area of the pull marks and wavy defects on the copper rod after continuous casting exceeds the second area threshold, the continuous casting speed is reduced. For example, when the area of the pull marks or wavy defects exceeds the second threshold (such as 5%), the continuous casting speed is reduced from 1.8 m / min to 1.6 m / min.

[0065] Through steps S321 to S327, real-time detection and dynamic adjustment are used to reduce surface defects and oxygen content in the copper rod. Precise control of the shielding gas flow rate and cooling rate reduces shielding gas consumption and cooling energy consumption. Dynamic optimization of the continuous casting speed improves production efficiency while reducing downtime caused by quality defects. Conditional judgment and formula-based adjustments reduce manual intervention and achieve intelligent operation of the continuous casting process.

[0066] S330: When the first quality data meets the adjustment condition, adjust the continuous casting parameters according to the adjustment direction.

[0067] For example, when the first quality data meets the adjustment conditions, the continuous casting parameters can be adjusted according to the adjustment direction, and sampling and testing can be carried out immediately after the adjustment. If the test is qualified for three consecutive times (such as oxygen content ≤410ppm, defect length ≤0.4mm), the adjustment is stopped.

[0068] Through steps S310 to S330, the adjustment response time is shortened and the production interruption rate is reduced. The adjustment plan based on quantitative scoring and mapping tables reduces parameter adjustment deviations and avoids quality fluctuations caused by over-adjustment. The improved stability of the continuous casting process reduces the wire breakage rate in the subsequent rolling process. Through data-driven closed-loop adjustment, the coordinated optimization of quality, efficiency, and cost is achieved, providing an intelligent solution for copper rod continuous casting production.

[0069] In one possible implementation, see Figure 3 S300, adjusting the continuous casting parameters according to the first quality data of the copper rod after continuous casting using the continuous casting parameters, further comprising: S301: When there is only one first adjustment target, obtain a first weight according to the influence of the continuous casting parameter on the first adjustment target in the adjustment direction.

[0070] For example, historical production data may be analyzed through regression analysis or correlation analysis to calculate the influence coefficient of each parameter adjustment in the continuous casting parameters on the first adjustment target, and the influence coefficient may be normalized to obtain the first weight.

[0071] S302: Obtain an adjustment range of a continuous casting parameter according to the first weight.

[0072] For example, a deviation between the first quality data and a corresponding qualified quality range, ie, a first target deviation, may be determined based on the first quality data, and an adjustment range of the continuous casting parameters may be calculated based on the first weight and the first target deviation.

[0073] S303: When the first adjustment target includes multiple targets, determine a second weight of each target in the first adjustment target and a third weight of the continuous casting parameter for each target in the first adjustment target under the adjustment direction.

[0074] For example, the second weight can be allocated according to the priority of each target in the second adjustment target, and for each target, the influence of the continuous casting parameters is calculated based on regression analysis or correlation analysis of historical production data and normalized into a third weight.

[0075] S304: Obtain an adjustment range of the continuous casting parameters according to the second weight and the third weight.

[0076] For example, for each parameter in the continuous casting parameters, the comprehensive adjustment range of the parameter to all the targets in the first adjustment target may be calculated according to the second weight and the third weight.

[0077] Through steps S301 to S304, weight allocation reduces quality fluctuations, improves product consistency, and stabilizes production. This avoids the deterioration of other quality indicators caused by single-target optimization and achieves synergistic improvements in indicators such as oxygen content, surface roughness, and internal defects. By quantifying weights and sensitivities, operators are provided with a scientific basis for adjustment, reducing reliance on experience.

[0078] S400: Obtaining the real-time thickness of the copper rod after continuous casting according to the adjusted continuous casting parameters.

[0079] For example, a laser thickness gauge can be used to monitor the diameter of the copper rod after continuous casting (eg, 8.02 mm) online, and the data can be transmitted to a PLC in real time to obtain the real-time thickness.

[0080] S500: Determine rolling parameters according to the real-time thickness.

[0081] For example, preset rolling parameters can be obtained, and the reduction amount of each rolling pass can be determined according to the preset rolling parameters (such as a total reduction of 15%, 5 rolling passes, and distribution according to an exponential function), the reduction amount of each rolling pass can be compared with the real-time thickness, and the rolling parameters can be obtained after adjusting the preset rolling parameters.

[0082] In one possible implementation, see Figure 4 S500: rolling parameters include rolling temperature, reduction, rolling speed and tension of each rolling pass. The rolling parameters are determined according to the real-time thickness, including: S510: Obtain thickness deviation based on the real-time thickness and the target thickness, wherein the target thickness includes the expected thickness of each rolling pass.

[0083] For example, the exit thickness of each rolling pass, i.e., the real-time thickness, can be collected in real time by a laser thickness gauge or an X-ray thickness gauge, and the real-time thickness can be compared with the preset target thickness to obtain the thickness deviation. For example, thickness deviation = h 实时 −h 目标 , where h 实时 is the real-time thickness, h 目标is the target thickness.

[0084] S520, adjusting the reduction amount of the next rolling pass according to the thickness deviation of the current rolling pass.

[0085] For example, the reduction of the next rolling pass can be adjusted according to the thickness deviation of the current rolling pass. 下一 =Δh 设定 +k×thickness deviation, where Δh 下一 is the adjusted reduction for the next rolling pass, Δh 设定 is the preset reduction for the next rolling pass, and k is the adjustment coefficient.

[0086] S530, calculating the rolling speed of the next rolling pass according to the reduction amount of the next rolling pass, the real-time thickness and the target thickness, and adjusting the rolling speed of the previous rolling pass.

[0087] For example, a rolling speed prediction model can be established using a multi-layer perceptron (MLP) or a recurrent neural network (RNN) based on historical production data, with the reduction amount, real-time thickness and target thickness as input, the rolling speed of the next rolling pass as output, and the rolling speed of the previous rolling pass adjusted according to the rolling speed of the next rolling pass and the rolling speed of the current rolling pass.

[0088] Optionally, see Figure 4 S530, calculating the rolling speed of the next rolling pass according to the reduction amount and real-time thickness of the next rolling pass, and adjusting the rolling speed of the previous rolling pass, including: S531, obtaining a reduction adjustment coefficient according to the reduction of the next rolling pass and the standard reduction.

[0089] For example, the standard reduction amount may be divided by the reduction amount of the next rolling pass to obtain the reduction amount adjustment coefficient.

[0090] S532: Obtain a thickness adjustment coefficient according to the real-time thickness and the target thickness.

[0091] For example, the target thickness may be divided by the real-time thickness to obtain the thickness adjustment coefficient.

[0092] S533, obtaining the rolling speed of the next rolling pass according to the rolling speed, reduction adjustment coefficient and thickness adjustment coefficient of the current rolling pass.

[0093] For example, the rolling speed of the next rolling pass may be obtained by multiplying the rolling speed, the reduction adjustment coefficient, and the thickness adjustment coefficient of the current rolling pass.

[0094] S534: Obtain a speed coordination factor according to the rolling speed of the next rolling pass and the rolling speed of the current rolling pass.

[0095] For example, the speed coordination factor may be obtained by dividing the rolling speed of the next rolling pass by the rolling speed of the current rolling pass.

[0096] S535, adjusting the rolling speed of the previous rolling pass according to the speed coordination factor.

[0097] For example, the speed coordination factor may be multiplied by the rolling speed of the previous rolling pass to obtain the adjusted rolling speed of the previous rolling pass.

[0098] Through steps S531 to S535, the coordinated adjustment of rolling reduction, thickness, and rolling speed reduces metal flow deviations between passes, eliminating the risk of steel accumulation or steel pulling. Dynamic correction of the thickness adjustment coefficient reduces thickness deviations and improves product qualification rates. Reverse adjustment of the speed coordination factor aligns the speed of the previous rolling pass with the speed of the next, reducing equipment failure rates. This allows rolling at higher rolling reductions, improving production efficiency while maintaining thickness stability.

[0099] S540: Adjust the tension and rolling temperature of the next rolling pass according to the rolling speed and reduction of the next rolling pass.

[0100] For example, a model (multivariate linear regression model, multi-layer perceptron (MLP), convolutional neural network (CNN), etc.) can be established based on historical production data to respectively relate tension and rolling temperature to rolling speed and reduction, and the rolling speed and reduction of the next rolling pass are input into the model to obtain the tension and rolling temperature of the next rolling pass.

[0101] Through steps S510 to S540, the coordinated adjustment of rolling reduction and rolling speed reduces thickness deviation and improves product qualification rate. By balancing metal flow and optimizing tension, steel accumulation and pulling accidents are eliminated, reducing equipment failure rate. Dynamic temperature adjustment allows rolling at a higher rolling reduction, improving production efficiency. By reducing scrap caused by thickness deviations, material utilization is improved and energy consumption is reduced.

[0102] S600: Adjust the rolling parameters according to second quality data of the copper rod after continuous rolling using the rolling parameters, wherein the second quality data includes oxygen content, surface defects, and dimensions of the copper rod in each rolling pass.

[0103] For example, whether the quality of the copper rod in each rolling pass is qualified can be determined based on the second quality data of the copper rod after continuous rolling using the rolling parameters. If it is determined based on the second quality data that the oxygen content, surface defects or size of the copper rod in a certain rolling pass exceed a quantity threshold, then the quality of the copper rod in this rolling pass is determined to be unqualified, and the rolling parameters of this rolling pass and subsequent rolling passes are adjusted based on the deviation between the second quality data and the qualified quality range.

[0104] In one possible implementation, see Figure 5 S600, adjusting the rolling parameters according to the second quality data of the copper rod after continuous rolling using the rolling parameters, including: S610: Determine a second adjustment target for each rolling pass based on the second quality data, wherein the second adjustment target includes reducing surface defects and / or improving dimensional accuracy.

[0105] For example, data such as oxygen content deviation, length or area of surface defects, and size deviation can be converted into a standardized score (0 to 100 points) based on the second quality data, and the standardized score can be compared with a preset score threshold to determine the second adjustment target.

[0106] S620: Determine a corresponding second adjustment plan according to each second adjustment target, wherein the second adjustment plan includes an adjustment condition and an adjustment direction.

[0107] For example, historical production data can be used to train a machine learning model (such as a decision tree, a neural network) to predict the impact of the adjustment of rolling parameters on the second adjustment target, establish a mapping relationship table between the second adjustment target and the rolling parameters, and determine the second adjustment plan based on the mapping relationship table.

[0108] Optionally, see Figure 5 S620: Determine a corresponding second adjustment plan according to each second adjustment target, including: S621: When the second adjustment target includes reducing surface defects, the adjustment direction in the second adjustment scheme includes adjusting the rolling temperature and / or adjusting the rolling speed.

[0109] For example, when the second adjustment target includes reducing surface defects, the rolling temperature and / or the rolling speed may be adjusted.

[0110] S622: When the second adjustment target includes improving dimensional accuracy, the adjustment direction in the second adjustment solution includes adjusting the rolling speed.

[0111] For example, the rolling speed can be adjusted when the second adjustment target includes improving dimensional accuracy. For example, if the size is too large, the rolling speed can be reduced (such as from 6 m / s to 5.5 m / s) to increase the rolling force; if the size is too small, the rolling speed can be increased (such as from 5 m / s to 5.5 m / s) to reduce the rolling force.

[0112] S623: When the rolling temperature needs to be increased, the adjustment condition includes that the area of cracks and scratches on the copper rod after a certain rolling pass exceeds a third area threshold.

[0113] For example, when the area of cracks and scratches on the copper rod after a certain rolling pass exceeds a third area threshold (such as 2%), the rolling temperature is increased. For example, if the crack and scratch area is 2.5%>2%, the rolling temperature is increased from 720°C to 750°C.

[0114] S624, in the case where the rolling temperature needs to be lowered, the adjustment conditions include the occurrence of overheating, burnt areas or melting phenomena.

[0115] For example, when overheating, burnt area or melting occurs, the rolling temperature is lowered. For example, if the burnt area accounts for 0.5%>0.1%, it is determined that a burnt area has occurred, and the rolling temperature is lowered from 850°C to 800°C.

[0116] S625, when the rolling speed needs to be increased, the adjustment conditions include that the size of the copper rod after a certain rolling pass is smaller than a first size threshold or the surface roughness of the copper rod after a certain rolling pass is greater than a second roughness threshold.

[0117] For example, when the size of the copper rod after a certain rolling pass is smaller than a first size threshold or the surface roughness of the copper rod after a certain rolling pass is greater than a second roughness threshold, the rolling speed is increased. For example, when the size of the copper rod after a certain rolling pass is smaller than a first size threshold (such as 9.9 mm) or the surface roughness is greater than a second roughness threshold (such as 3.2 μm), the rolling speed is increased from 4 m / s to 4.5 m / s.

[0118] S626, when the rolling speed needs to be reduced, the adjustment conditions include that the size of the copper rod after a certain rolling pass is greater than the second size threshold, the size change of the copper rod after a certain rolling pass is not within the fluctuation range, or the area of cracks and scratches on the copper rod after a certain rolling pass exceeds the third area threshold.

[0119] Exemplarily, the rolling speed may be reduced when the size of the copper rod after a certain rolling pass is greater than the second size threshold, the size change of the copper rod after a certain rolling pass is not within the fluctuation range, or the area of cracks and scratches on the copper rod after a certain rolling pass exceeds the third area threshold. For example, when the size of the copper rod after a certain rolling pass is greater than the second size threshold (such as 10.05 mm), the size change is not within the fluctuation range (such as ±0.01 mm), or the area of cracks and scratches exceeds the third area threshold (such as 2%), the rolling speed is reduced from 5 m / s to 4.5 m / s.

[0120] Through steps S621 to S626, real-time monitoring of crack / scratch area, dimensional deviation, and roughness allows targeted adjustments to temperature and speed to reduce surface defects and dimensional deviations. Dynamic adjustment of rolling parameters can minimize dimensional fluctuations and reduce surface roughness. Real-time monitoring of overheating and melting prevents equipment damage caused by high temperatures and extends equipment life. Rapid response to quality defects reduces downtime and defective product rates, thereby improving production efficiency.

[0121] S630: When the second quality data meets the adjustment condition, adjust the rolling parameters according to the adjustment direction.

[0122] For example, when the second quality data meets the adjustment condition, the rolling parameters may be adjusted according to the deviation between the second quality data and the qualified quality range in the adjustment direction.

[0123] Through steps S610 to S630, the correlation model between quality data and parameters enables targeted repair of surface defects and dimensional deviations, reducing the defective rate caused by blind adjustments. Dynamic parameter adjustment shortens adjustment cycles, reduces downtime, and improves production efficiency. By reducing surface defects and dimensional deviations, material utilization is increased, and lubricant and energy consumption are reduced. Through iterative adjustments, rolling process stability is improved, equipment failure rates are reduced, and maintenance costs are reduced.

[0124] In one possible implementation, see Figure 6 S600, adjusting the rolling parameters according to the second quality data of the copper rod after continuous rolling using the rolling parameters, further comprising: S601: When there is only one second adjustment target, obtain a fourth weight according to the degree of influence of the rolling parameter on the second adjustment target in the adjustment direction.

[0125] For example, an association model between rolling parameters and the second adjustment target (such as a multivariate linear regression model, a support vector machine model, etc.) can be established through historical production data to quantify the degree of influence of the rolling parameters on the second adjustment target, and the degree of influence can be normalized to a fourth weight.

[0126] S602: Obtain an adjustment range of the rolling parameter according to the fourth weight.

[0127] For example, the deviation between the second quality data and the corresponding qualified quality range, ie, the second target deviation, can be obtained based on the second quality data, and the adjustment range of the rolling parameters can be calculated based on the fourth weight and the second target deviation.

[0128] S603 , when the second adjustment target includes multiple targets, determine a fifth weight of each target in the second adjustment target and a sixth weight of the rolling parameter to each target in the second adjustment target under the adjustment direction.

[0129] Exemplarily, a fifth weight can be assigned according to the priority of each target in the second adjustment target. For each target, the influence of the rolling parameters is calculated according to an association model (such as a multivariate linear regression model, a support vector machine model, etc.) and normalized to a sixth weight.

[0130] S604: Obtain an adjustment range of the rolling parameters according to the fifth weight and the sixth weight.

[0131] For example, for each rolling parameter, the comprehensive adjustment range of the parameter to all targets in the second adjustment target can be calculated according to the fifth weight and the sixth weight.

[0132] Through steps S601 to S604, the fifth and sixth weights can be used to quantify the comprehensive contribution of parameters to multiple objectives, achieving coordinated optimization of surface defect rate and dimensional accuracy, thereby reducing the defective rate. The fourth and sixth weights can be used to quantify the contribution of parameters to the target, ensuring that the adjustment range is proportional to the target deviation, avoiding over-adjustment or under-adjustment. By assigning weights and calculating the adjustment range, dimensional fluctuations can be minimized, reducing the surface defect rate and improving process stability. By quickly responding to quality defects, downtime and defective rates can be reduced, thereby improving production efficiency.
