[0002] Titanium alloys are widely used in aerospace, medical, chemical and other fields due to their excellent strength, corrosion resistance and light weight. However, in the actual production process, after multiple rolling passes at room temperature, the deformation resistance of titanium alloy plates increases sharply, resulting in rolling difficulties. Therefore, it is usually necessary to transfer the plates to other production lines for annealing to reduce the deformation resistance, and then return them for subsequent rolling. This process is very cumbersome, resulting in low operating efficiency of the overall production line. In addition, if the temperature of titanium alloy plates drops too quickly during transportation, it will also have an adverse effect on subsequent production. Summary of the invention

[0050] This embodiment provides a cold rolling method, device, equipment and storage medium for a titanium alloy plate.

[0051] like Figure 1 As shown, a cold rolling method for a titanium alloy plate provided in an embodiment of the present invention is applied to a cold rolling system, wherein the cold rolling system includes a heat preservation system, and the cold rolling method for a titanium alloy plate includes:

[0052] Step S100, obtaining the current titanium alloy plate.

[0053] Specifically, according to the production order or customer needs, confirm the required titanium alloy plate type, specification and thickness. Usually includes determining the required chemical composition, physical properties, etc. to ensure that it meets the specific application. Select titanium alloy plates that meet the standards from the material library or storage area. When selecting, factors such as the thickness, width, length and surface condition of the plate should be considered to ensure that it meets the requirements of the rolling process.

[0054] Carry out necessary inspections on the selected titanium alloy plates, such as: Appearance inspection: Check whether there are obvious scratches, dents and other defects on the surface. Thickness measurement: Use a thickness gauge to confirm whether the actual thickness of the plate is within the preset range to avoid material deviation affecting subsequent rolling. Hardness test: Perform appropriate hardness or other physical property tests as needed to ensure that it is suitable for the cold rolling process.

[0055] Step S200, controlling the current titanium alloy plate to enter a rolling process, the rolling process comprising: repeatedly rolling the current titanium alloy plate based on preset parameters until the hardening state of the titanium alloy plate reaches a predetermined standard, stopping the rolling process, and obtaining a hardened titanium alloy plate.

[0056] Specifically, step S200 is an important step in the cold rolling process of the titanium alloy sheet, which involves feeding the obtained titanium alloy sheet into a cold rolling device and performing repeated rolling to achieve a desired hardened state.

[0057] In the feeding area of ​​the cold rolling mill, the conveying of titanium alloy plates is monitored and controlled to ensure that they enter the rolling equipment smoothly (the cold rolling system includes rolling equipment, such as a four-roll cold rolling mill 4. Sensors or automation devices are used to determine the position and state of the material and start the rolling process at the appropriate time.

[0058] According to the characteristics of titanium alloy and the expected rolling effect, the preset parameters of the rolling process are set. These parameters usually include: Rolling pressure: controlled within a specific range to ensure plastic deformation without material cracking. Rolling speed: The rolling speed is appropriately selected to ensure processing efficiency while avoiding overheating of the material.

[0059] The rolling mill is started to roll the titanium alloy plate repeatedly. Each rolling will exert pressure on the plate, gradually reducing its thickness and increasing the strength and hardening of the material. During the rolling process, the material status is monitored in real time to ensure that the rolling is always within the appropriate temperature and pressure range. If any abnormal situation occurs, the rolling is adjusted or suspended immediately.

[0060] The hardening of the titanium alloy sheet is monitored by sensors, monitoring systems or data acquisition systems in the equipment. When it is detected that the material reaches the preset hardness or hardening state, this state will be automatically recorded and the rolling process will be suspended.

[0061] The rolling process is controlled automatically, which reduces manual intervention and human errors, significantly improves the rolling speed and stability, and thus improves the overall production efficiency. The repeated rolling increases the strength, hardness and wear resistance of the titanium alloy sheet, improves the microstructure of the material, and makes the final product more reliable and adaptable to various harsh environments. At the same time, the rolling parameters are flexibly adjusted according to the properties of the titanium alloy material to meet the requirements of materials of different thicknesses and specifications, which improves the flexibility and pertinence of the production process.

[0062] Real-time monitoring of the hardening status ensures that each batch of products can meet the set indicators, greatly reducing the production of defective products and also reducing production losses caused by material performance problems.

[0063] Step S300, heating the hardened titanium alloy plate to a preset temperature through the insulation system to obtain a heated titanium alloy plate; using the heated titanium alloy plate as the current titanium alloy plate, and returning to perform the rolling process, repeating the above steps until the thickness of the current titanium alloy plate reaches the preset thickness, to obtain a final titanium alloy plate.

[0064] Specifically, in the process flow, step S300 is crucial for the subsequent rolling of the titanium alloy plate. This step heats the hardened titanium alloy plate through the heat preservation system to return it to a suitable processing temperature, thereby increasing the plasticity of the material and providing conditions for subsequent rolling.

[0065] The hardened titanium alloy plate obtained from the previous step S200 enters the heating stage to confirm whether its state and specifications meet the heating requirements. The hardened titanium alloy plate is sent to the insulation system to ensure that the plate does not come into direct contact with the outside world during the heating process to prevent heat from being lost too quickly. Check the temperature setting of the insulation system to ensure that the preheating temperature has been calibrated to an appropriate preset value. The preset temperature is usually determined according to the specifications and processing requirements of the material, generally between 400°C and 800°C. Turn on the insulation system, such as an insulation furnace, to gradually heat up the titanium alloy plate in the insulation furnace. During the heating process, the temperature should be evenly distributed, and the temperature control system and sensor can be used to monitor the temperature of the plate in real time. The heating time is adjusted according to the thickness and initial temperature of the material to ensure that the plate reaches the set heating temperature. During the process, the material should be prevented from overheating or other changes in physical state due to excessive heating.

[0066] Once the titanium alloy plate reaches the preset temperature, the system should automatically record and generate a data report for reference in subsequent operations. At the same time, ensure that the heating state is stable so that the plate remains at this temperature suitable for rolling. The heated titanium alloy plate is used as the "current titanium alloy plate" and is re-sent into the rolling mill for subsequent rolling. All relevant parameters (such as rolling pressure, speed, etc.) should be adjusted according to the state of the material after heating to adapt to the new rolling requirements. Repeat steps S200 and S300 and continue this cycle until the titanium alloy plate reaches the preset final thickness (preset thickness).

[0067] The heating process in the production process can significantly improve the plasticity of the titanium alloy, reduce the deformation resistance of the material during the rolling process, make the subsequent rolling smoother, and effectively reduce the occurrence of fractures, cracks and other phenomena. And through the correct heating temperature control, the characteristics of the titanium alloy plate rolled each time are ensured to be consistent, and the quality stability of the final product is improved. That is, the mutual circulation of the insulation system and the rolling process is combined to improve the continuity of the entire production process, and reduce production interruptions and unnecessary waiting time caused by temperature loss. Therefore, by effectively managing the heating process, the rolling equipment is operated in an efficient state, the idle and non-production time are reduced as much as possible, and the overall utilization rate of the equipment is improved. At the same time, systematic temperature monitoring and control ensure that the operation is within a safe range, which helps to reduce the risks of equipment damage, personal injury and the like caused by temperature runaway. That is, through the effective implementation of step S300, the titanium alloy plate can be smoothly advanced after hardening treatment, and efficient and continuous cold rolling processing can be achieved.

[0068] In this embodiment, the cold rolling method of the titanium alloy plate first obtains the current titanium alloy plate, and a suitable titanium alloy plate can be obtained from a production line or a warehouse to prepare for rolling. The selected titanium alloy plate (current titanium alloy plate) is sent to the rolling equipment and repeatedly rolled according to the set preset parameters. This process will continue until the hardening state of the material reaches the predetermined standard, and then the rolling is stopped. The hardened titanium alloy plate is heated by the insulation system, and when the temperature rises to the preset level, the plate is processed again. Such a heating process can enhance the plasticity of the material and facilitate subsequent rolling. The heated titanium alloy plate is put back into rolling, and the preset number of rollings is continued until the set final thickness is reached to form a standard titanium alloy plate product.

[0069] This method can reduce production interruptions caused by temperature drop by combining the insulation system and the heating furnace, thereby improving overall production efficiency and continuity. The combination of repeated rolling and heating helps to improve the microstructure of titanium alloy, enhance its strength and toughness, and ultimately obtain titanium alloy plates with higher performance. And through the cold rolling system, the rolling parameters can be flexibly adjusted according to the change of the thickness of the raw material, which is suitable for the production of titanium alloy plates of different specifications and thicknesses to meet market demand. At the same time, in the overall production process, by removing cumbersome production links (such as annealing), the time and labor costs in the production process are reduced, that is, while ensuring production efficiency, the application of the insulation system helps to reduce energy consumption. By effectively controlling the heating and rolling process, the waste of heat energy can be reduced. At the same time, by improving the qualified rate and reducing the defective rate, the overall production cost is further reduced. And this scheme can optimize the rolling of titanium alloy plates of different thicknesses and types, improve the utilization rate and adaptability of the equipment, and make the operation of the production line more efficient.

[0070] Therefore, the cold rolling method of titanium alloy sheet not only optimizes the production process and improves product quality and efficiency, but also has flexibility and economy, adapting to the complex needs of today's titanium alloy sheet production. In addition, the cold rolling system can integrate intelligent control systems to achieve process automation, improve the overall operating efficiency of the production line, and reduce the need for manual intervention.

[0071] Optionally, the cold rolling system further includes a first transport roller 3, a second transport roller 5 and a four-roller cold rolling mill 4, wherein the first transport roller 3 and the second transport roller 5 are symmetrically arranged on both sides of the four-roller cold rolling mill 4; the current titanium alloy plate is repeatedly rolled based on preset parameters until the hardening state of the titanium alloy plate reaches a predetermined standard, and the rolling process is stopped, comprising:

[0072] The titanium alloy sheet is transported to the four-roller cold rolling mill 4 through the first transport roller 3, the titanium alloy sheet is pressed and rolled according to the preset parameters based on the four-roller cold rolling mill 4, and the titanium alloy sheet after rolling is transported to the second transport roller 5 under control;

[0073] Control the second transport roller 5 to transport the titanium alloy plate to the four-roller cold rolling mill 4 in the reverse direction for rolling, roll the titanium alloy plate according to the preset parameters based on the four-roller cold rolling mill 4, and control the rolled titanium alloy plate to the first transport roller 3;

[0074] The rolling process is repeated until the hardening state of the titanium alloy plate reaches a predetermined standard, and then the rolling process is stopped.

[0075] Specifically, Figure 2 As shown, in the cold rolling system, the designs of the first transport roller 3, the second transport roller 5 and the four-roller cold rolling mill 4 constitute an efficient and cyclic processing flow.

[0076] Transport by the first transport roller 3 (i.e. the transport roller or chain before the rolling mill): The obtained titanium alloy plate (current titanium alloy plate) is sent from the storage area to the first transport roller 3, which is responsible for transporting the material to the four-roll cold rolling mill 4. During transportation, ensure that the material is fully supported and properly aligned. Once the titanium alloy plate arrives at the four-roll cold rolling mill 4, rolling will be performed according to preset parameters. These parameters usually include rolling pressure, speed, temperature control, etc., with the aim of gradually reducing the thickness of the plate during repeated rolling. During the rolling process, the four-roll mill uses working rolls to roll the plate. Control the rolled plate to the second transport roller 5: After rolling is completed, the cold rolling mill accurately delivers the rolled titanium alloy plate to the second transport roller 5. This process requires a high degree of automated control to prevent the material from slipping or becoming chaotic.

[0077] The second transport roller 5 (i.e., the transport roller or chain after the rolling mill) transports in reverse: the transport direction of the second transport roller 5 is controlled so that it can send the rolled titanium alloy sheet back to the four-roller cold rolling mill 4. This process is cyclical, and the purpose is to use a new round of rolling to further improve the hardening state of the material.

[0078] In the four-roller cold rolling mill 4, the same rolling operation as before is performed on the returned titanium alloy sheet, and rolling is performed again according to the preset parameters. After completion, the material is again sent to the first transport roller 3 through control, and the cycle continues, so that the effect of each rolling is accumulated.

[0079] The above steps are repeated, with periodic transportation and rolling, until the hardening state of the titanium alloy plate reaches a predetermined standard, and then the rolling process is automatically stopped.

[0080] By constructing an efficient combination of the transport roller and the four-roller cold rolling mill 4, the seamless connection of the materials on the production line is ensured, making the entire rolling process smooth and efficient, and reducing downtime. The system has a high degree of automation and can monitor the rolling parameters and the transportation process in real time, which not only improves the accuracy of the operation, but also ensures the safety of the production process. The design allows titanium alloy plates of different thicknesses and specifications to be continuously rolled in a cycle to meet diverse production needs and increase the adaptability of the system. At the same time, the automated transportation system reduces the need for manual operation, reduces the probability of human error, and improves the overall safety and efficiency of production.

[0081] Through the above steps and optimized design, the cold rolling system improves the production efficiency and product quality of titanium alloy plates.

[0082] Optionally, the insulation system also includes a first insulation device 6 and a second insulation device 7, and the first insulation device 6 and the second insulation device 7 are respectively symmetrically arranged on the supporting structure of the transport roller, and the first insulation device 6 and the second insulation device 7 are both used to heat the titanium alloy plate during the rolling process to achieve online temperature compensation, wherein the transport roller includes the first transport roller 3 and the second transport roller 5.

[0083] Optionally, the heat preservation system further includes a heat preservation device 1 , and the heat preservation device 1 is used to heat the titanium alloy plate before the titanium alloy plate enters the first transport roller 3 .

[0084] Specifically, in the cold rolling system, the effective design of the insulation system is crucial to ensure that the titanium alloy plate maintains a suitable temperature throughout the rolling process. The system includes a first insulation device 6 and a second insulation device 7, and is also equipped with a special insulation device 1, which will help improve the rolling effect.

[0085] Before the titanium alloy plate enters the first transport roller 3, it is first preheated by the heat preservation device 1. The device can use electric heating elements or other heating methods to ensure that the titanium alloy plate is heated to a temperature close to that required for rolling, thereby improving its plasticity and reducing deformation resistance during subsequent rolling.

[0086] The titanium alloy sheet is first transported on the first conveyor roller 3, and then rolled on the four-roller cold rolling mill 4, and then reaches the second conveyor roller 5. Both are equipped with insulation devices, which are respectively located on the support structure of the conveyor rollers to ensure that the temperature of the sheet is maintained during transportation. The first insulation device 6 heats the titanium alloy sheet transported to the four-roller cold rolling mill 4, while the second insulation device 7 is used to supplement the temperature of the returned titanium alloy sheet to prevent the temperature drop caused by roller transportation.

[0087] During the rolling process, the first heat preservation device 6 and the second heat preservation device 7 monitor the temperature in real time to perform dynamic heating or heat preservation to ensure that the temperature of the plate remains appropriate during the rolling process.

[0088] If the temperature is found to be lower than the set value, the heat preservation device will automatically start heating to help maintain the best rolling state of the titanium alloy. The heat preservation system and the transport roller are controlled to work together. The first heat preservation device 6 and the second heat preservation device 7 are connected to the transport roller to ensure that the temperature of the material can be maintained during the movement gap and reduce the cooling time.

[0089] Therefore, online temperature compensation through the insulation system can greatly reduce the fluctuation of material properties caused by temperature reduction, ensure the uniformity and stability of titanium alloy during rolling, and dynamically heat the material during transportation and rolling to accurately control the heating demand and avoid overheating, thereby saving energy consumption and achieving energy conservation and environmental protection. In addition, suitable heating conditions enhance the plasticity of the material and reduce the deformation resistance during rolling, thereby improving the quality of the final product and reducing the risk of material breakage or damage. At the same time, by integrating the insulation device into the transport roller to form an integrated production line, interruptions and processing failures caused by temperature changes are reduced, and overall production efficiency is improved. The automated insulation process reduces the need for manual intervention, improves the controllability and safety of the system, reduces operating costs and reduces the probability of errors.

[0090] Optionally, the four-roller cold rolling mill 4 includes a first working roll and a second working roll; the cold rolling method of the titanium alloy plate further includes:

[0091] At the current titanium alloy sheet blanking stage,

[0092] Roughly rolling the current titanium alloy plate to an initial thickness by the first working roller to obtain a temporary titanium alloy plate;

[0093] Finish rolling the temporary titanium alloy plate to the preset thickness by the second working roller to obtain the final titanium alloy plate;

[0094] Wherein, the diameter of the first working roll is greater than the diameter of the second working roll.

[0095] Specifically, in the cold rolling process of titanium alloy plates, the design and operation of the four-roll cold rolling mill 4 play a key role. At present, the current production equipment faces another challenge: titanium alloy plates are usually thicker in the blanking stage, and a larger rolling force and a large-sized working roll are required to obtain the required reduction. After the titanium alloy plate is thinned by rolling, due to the limitations of the bite angle and the thinnest rollable thickness, a smaller diameter working roll is required to produce thin-gauge plates. Existing rolling mills cannot effectively meet this change in demand, so new solutions are needed.

[0096] In some embodiments, such as Figure 3 As shown, the four-roller cold rolling mill 4 includes a rolling mill frame 41, a pressing AGC cylinder 42, a support roll system 43, a working roll system 44, a working roll balance bending device 45 and a wedge zeroing device 46; wherein the working roll system 44 includes a first working roll or a second working roll. For example, the specifications of the first working roll are: Φ475 / Φ425 and the specifications of the second working roll are Φ365 / Φ340 (the initial diameter of the working roll and the diameter after wear).

[0097] At the current stage of billeting of titanium alloy plates, the material has just entered the rolling process, and the material is usually required to reach a certain temperature and state before rough rolling begins.

[0098] Rough rolling process (first working roll): The current titanium alloy plate is rough rolled using the first working roll with a larger diameter. The main goal of this stage is to quickly reduce the thickness of the plate and process it to the initial thickness. Due to the large diameter of the first working roll, a larger pressure can be effectively applied to improve the rolling effect, thereby quickly changing the shape of the material and improving its surface flatness. After rough rolling, the resulting product is called a temporary titanium alloy plate, and the thickness at this time has been reduced, but it does not meet the final specifications.

[0099] Finishing process (second working roll): Next, the temporary titanium alloy sheet enters the second process and is finished by the second working roll with a smaller diameter. If the second working roll is required for the finishing process, the working rolls in the working roll system 44 of the four-roll cold rolling mill 4 need to be replaced, that is, the first working roll is replaced with the second working roll. The function of the second working roll is to further refine the thickness of the material and improve its surface quality. Due to the small diameter and the high applied pressure, the rolling process can be more accurately controlled to achieve the preset thickness of the sheet. After the finishing process, the material will reach the designed final thickness and have the required strength and smooth surface characteristics, ready for subsequent processing or application.

[0100] The use of a staged approach of rough rolling and finishing rolling reduces the load at each step, making the process more efficient and helping to quickly reach the preset thickness. Rough rolling can quickly flatten the plate and reduce initial defects, while finishing rolling can achieve a higher surface finish and accurately control the final thickness, ensuring that the final product meets strict standards. The combined use of the first working roll and the second working roll allows each process to be carried out under optimal conditions, helping to reduce overall energy consumption and improve energy utilization.

[0101] The setting between rough rolling and finishing rolling allows the design to flexibly cope with titanium alloy plates of different thicknesses and specifications, enhancing the adaptability of the production line. It solves the problem of the limitation of the bite angle and the thinnest rollable thickness after the titanium alloy plate is rolled thin. That is, it avoids the limitation of the bite angle and the thinnest rollable thickness, and can produce thinner specifications of plates.

[0102] Optionally, the four-roller cold rolling mill 4 includes a pressing AGC cylinder 42, and the cold rolling method of the titanium alloy plate includes:

[0103] Get the preset distance parameters;

[0104] During the rolling process, based on the preset distance parameter, the press-down AGC cylinder 42 is controlled to automatically adjust the relative position with the working roll;

[0105] Wherein, the working roll is the first working roll or the second working roll.

[0106] Specifically, before rolling begins, the preset distance parameters that the titanium alloy plate needs to reach after rolling are obtained through a pre-set calculation and measurement method. These parameters usually take into account factors such as material properties, initial thickness, target thickness, rolling speed, etc. In the actual rolling process, the AGC cylinder 42 is pressed down to automatically adjust the relative position with the working roll (the first working roll or the second working roll) according to the preset distance parameters. That is, the AGC cylinder 42 and the working roll balance bending roll device 45 are designed with a long stroke to meet the requirements of the two diameters of the large and small working rolls (the first working roll and the second working roll). This control method selects the appropriate working roll for adjustment according to the actual rolling requirements, thereby optimizing the overall rolling effect.

[0107] By using sensors to monitor the rolling thickness and contact status of the working rolls in real time, the AGC cylinder will respond to changes in the material and automatically adjust the spacing between the working rolls to ensure that rolling is always carried out at appropriate pressure and spacing.

[0108] Due to the rapid response to material changes, the automatic adjustment of the AGC cylinder eliminates the need for frequent shutdowns for manual corrections during the rolling process, improving overall production efficiency. This method can flexibly adapt to the rolling needs of materials of different specifications and thicknesses, enhancing the production line's ability to respond to market demand and improving the versatility of the system.

[0109] Optionally, the four-roller cold rolling mill 4 adopts a working roll transmission design. The main motor directly drives the working roll through a composite reducer and a transmission shaft, so that the working roll can withstand the torque generated during the rolling process.

[0110] Traditional titanium alloy four-roller cold rolling mills use a bearing roller transmission. In cold rolling mills using bearing roller transmission, the main design problem lies in the limitation of special transmission couplings. The transmission torque of small-sized couplings is insufficient to meet the high torque requirements for rolling titanium alloy plates. Titanium alloys require greater force during rolling due to their high strength and toughness. In addition, the bearing roller transmission requires that the diameter difference between the upper and lower roller systems must be strictly controlled. If there is a difference, it will lead to a speed difference between the rollers, thereby affecting the surface quality of the plate. This speed difference may cause uneven plate surface and even cause knocking and buckling, further affecting the rolling rhythm and the plate shape quality of the final product. In addition, when rolling with large-diameter working rolls, especially in the bite stage, the rolling torque of the working rolls is large, which makes it easy for the bearing rolls and working rolls to slip. This phenomenon not only affects the surface quality of the plate, but also significantly reduces the yield of the finished product because the material cannot be deformed evenly during the rolling process.

[0111] The four-roll mill provided in this embodiment adopts a design of working roll transmission, which solves the limitations of the above-mentioned support roll transmission. And it enables the small-diameter working roll to meet and withstand the torque required by the large-diameter working roll. This design ensures that the transmission force is transmitted more efficiently, avoids the occurrence of slippage, and improves the overall robustness and performance of the system. Due to the ability to better control the rolling force and reduce slippage, the cold rolling mill using working roll transmission can significantly improve the surface quality and thickness uniformity of titanium alloy plates, thereby improving the yield rate and ensuring the production needs of plates with diversified specifications. Therefore, the design using working roll transmission effectively solves the problems caused by support roll transmission and ensures the production of high-quality titanium alloy plates. This design not only helps to improve production efficiency and yield rate, but also helps to ensure the stability of the rolling process.

[0112] Optionally, the process of finish rolling the temporary titanium alloy plate to the preset thickness by the second working roller to obtain the final titanium alloy plate further comprises:

[0113] Acquire parameter information and production parameter information of the current titanium alloy plate in real time, wherein the parameter information includes temperature data and pressure data;

[0114] Processing the temperature data, the pressure data and the production parameter information based on a preset model to obtain a corresponding predicted thickness;

[0115] comparing the difference between the predicted thickness and the preset thickness with a preset error,

[0116] When the difference between the predicted thickness and the preset thickness is greater than the preset error, the working parameters of the cold rolling system are adjusted, and based on the adjusted working parameters, the temporary titanium alloy plate is finish rolled by the second working roller to obtain the final titanium alloy plate.

[0117] Specifically, in the cold rolling process of titanium alloy plates, real-time monitoring and intelligent processing technology can be used to more accurately control the parameters of the rolling process. This method includes real-time acquisition of temperature, pressure, and production parameters, as well as model-based predicted thickness calculation, and then adjusting production parameters to ensure that the thickness of the final product meets the standard.

[0118] During the finishing rolling process, the parameters of the rolling process can be controlled more accurately through real-time monitoring and intelligent processing technology. That is, the key parameter information of the current titanium alloy plate is continuously monitored, including temperature data, pressure data and other production parameters (such as rolling speed, workpiece position, working roll spacing, etc.). These data can be fed back to the control system through sensors to ensure real-time updates and adjustments.

[0119] Using data analysis and machine learning preset models, the real-time acquired temperature, pressure and other production parameter information is processed to calculate the predicted thickness of titanium alloy plates under current rolling conditions. The model should be trained based on historical data and physical laws to ensure the accuracy of the prediction.

[0120] According to the preset error range, the difference between the predicted thickness and the target (preset) thickness is compared. If the difference between the predicted thickness and the preset thickness is not within the allowable preset error range, adjustment is required.

[0121] When the difference is greater than the preset error, the operating parameters of the cold rolling mill are automatically adjusted. These adjustments may include changing the pressure of the second working roll, adjusting the rolling speed, or correcting the setting of the AGC cylinder to ensure that the rolling process always operates under optimal conditions.

[0122] Based on the new working parameters (adjusted working parameters), the temporary titanium alloy plate is finished rolled by the second working roller to ensure that the thickness of the final product reaches the preset target. This process should be monitored again to confirm whether the optimization effect is achieved.

[0123] During the entire finishing rolling process, continuous feedback is required for subsequent dynamic adjustments to ensure continued production efficiency and stability.

[0124] Through real-time monitoring and prediction mechanisms, thickness fluctuations are effectively reduced, and the consistency and reliability of the final product are enhanced. Timely parameter adjustments avoid material waste due to unqualified thickness and improve the overall utilization of materials. In addition, automated adjustments reduce the frequency of shutdown corrections, improve production efficiency, reduce production costs, and also reduce the need for human intervention, ensuring the safety of equipment and operators. At the same time, reasonable feedback and adjustment mechanisms enable the production line to quickly adapt to changes in market demand and improve the flexibility of the production system.
