DETAILED DESCRIPTION

[0019] In order to enable people in the technical field to better understand the present solution, the technical solution in the embodiment of the present solution will be clearly described below in conjunction with the drawings in the embodiment of the present solution. Obviously, the described embodiment is an embodiment of a part of the present solution, not all of the embodiments. Based on the embodiments in the present solution, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present solution.

[0020] The term "including" and any other variations in the specification and claims of this solution and the above drawings mean "including but not limited to", and is intended to cover non-exclusive inclusions and is not limited to the examples listed in the text. In addition, the terms "first" and "second" are used to distinguish different objects, not to describe a specific order.

[0021] The following is a detailed description of the implementation of the present disclosure in conjunction with the specific drawings: Figure 1 This is a schematic diagram of the structure of an automatic control system for a heat treatment device provided in an embodiment of the present disclosure. Figure 1 , the automatic control system of the heat treatment device includes: A heat treatment furnace 101, used for treating materials; The conveying module 102 is connected to the heat treatment furnace 101 and is used to convey the material into the heat treatment furnace 101; The detection module 103 is used to detect the working parameters of the heat treatment furnace 101; The positioning module 104 is connected to the conveying module 102 and is used to determine the material position of the conveying module 102; The control module 106 is respectively connected to the detection module 103, the positioning module 104, the heat treatment furnace 101, and the conveying module 102, and is used to determine the working mode of the heat treatment furnace 101 according to the material information of the material, and control the conveying speed of the conveying module 102 according to the working parameters and the material position.

[0022] In this embodiment, the heat treatment furnace 101 has a specific heating and heat preservation environment inside the cavity, and can perform heat treatment operations such as heating, heat preservation, and cooling on the material according to the set process requirements to change the physical and chemical properties of the material. The heat treatment furnace 101 heats the material to a predetermined temperature, maintains it for a period of time (heat preservation), and then cools it down at a specific speed to achieve the desired performance change. The purpose of heat treatment includes but is not limited to improving the mechanical properties of the material, removing stress, and improving wear resistance or corrosion resistance. For example, when quenching a metal material, the heat treatment furnace 101 can quickly heat the material to a specific high temperature and then quickly cool it to change the internal structure of the metal and improve its hardness and strength.

[0023] The conveying module 102 is connected to the heat treatment furnace 101 and is responsible for accurately and timely conveying the material to be processed into the heat treatment furnace 101. The conveying module 102 can be in various forms such as a conveyor belt, a mechanical push rod, a manipulator, etc. to meet the conveying requirements of materials of different shapes, sizes and weights.

[0024] For example, in a continuous heat treatment production line, the conveying module 102 can be a conveyor belt running at a uniform speed, which delivers materials into the heat treatment furnace 101 in sequence at certain time intervals; and for large and irregular materials, a robot can be used to accurately grasp and place them.

[0025] The detection module 103 is responsible for real-time detection of various working parameters of the heat treatment furnace 101, such as temperature, pressure, heating time, etc., which is very important for ensuring the quality of heat treatment and the stability of the process. The detection equipment may include various types of sensors and data acquisition systems.

[0026] For example, the temperature in the furnace cavity can be accurately measured by a thermocouple; the pressure sensor can detect the gas pressure in the furnace cavity to ensure the stability of the state in the furnace cavity.

[0027] The positioning module 104 is connected to the conveying module 102 and is responsible for determining the position information of the material on the conveying module 102, which is beneficial to subsequent operations and facilitates the control module 106 to more accurately control the conveying speed and time, ensuring that the material enters the heat treatment furnace 101 at the right time and is accurately conveyed to the designated position after the treatment is completed. For example, a photoelectric sensor or an encoder is used to determine the position of the material on the conveyor belt to provide accurate position data for the control module 106.

[0028] The control module 106 is responsible for receiving the relevant information of the detection module 103, the positioning module 104, the heat treatment furnace 101 and the conveying module 102, and can issue corresponding control instructions after analysis and processing. First, the optimal working mode of the heat treatment furnace 101 is determined according to the material information such as the type, specification, and processing requirements of the material, such as selecting a suitable temperature curve, heating time, and cooling method. At the same time, according to the working parameters of the heat treatment furnace 101 provided by the detection module 103 and the material position determined by the positioning module 104, the conveying speed of the conveying module 102 is dynamically adjusted to achieve accurate feeding and discharging of materials.

[0029] For example, if it is detected that the temperature in the furnace chamber has not reached the set value, the control module 106 will reduce the conveying speed and let the material wait outside the furnace; when the material position deviates from the predetermined position, the control module 106 will promptly adjust the operating parameters of the conveying module 102 for correction.

[0030] It can be concluded from the above that the present embodiment significantly improves production efficiency and product quality through integrated design. The present embodiment can detect the working parameters of the heat treatment furnace 101 in real time, ensure that the heat treatment process is accurately controllable, and effectively avoid the problem of uneven heat treatment caused by parameter fluctuations. At the same time, combined with the precise coordination of the positioning module 104 and the conveying module 102, the accurate tracking of the material position and the automatic adjustment of the conveying speed are realized, which not only optimizes the residence time of the material in the heat treatment furnace 101 cavity, but also greatly reduces the energy waste and safety hazards caused by position deviation. In addition, the control module 106 intelligently selects the working mode according to the material information, further improves the flexibility and adaptability of the heat treatment process, provides customized heat treatment solutions for materials of different materials and specifications, and promotes the intelligence and efficiency of the production process. Therefore, the present embodiment can improve the efficiency of heat treatment.

[0031] In one embodiment of the present disclosure, reference Figure 2 , the working parameters include temperature and pressure values; The detection module 103 includes a pressure detection unit 202 and a temperature detection unit 201; The pressure detection unit 202 is disposed in the furnace chamber of the heat treatment furnace 101 and connected to the control module 106, and is used to detect the pressure value of the heat treatment furnace 101 and send the pressure value to the control module 106; The temperature detection unit 201 is disposed in the furnace chamber of the heat treatment furnace 101 and connected to the control module 106 , and is used to detect the temperature value of the heat treatment furnace 101 and send the temperature value to the control module 106 .

[0032] In this embodiment, the working parameters mainly include temperature values ​​and pressure values, and the pressure detection unit 202 and the temperature detection unit 201 in the detection module 103 are responsible for the detection work.

[0033] The pressure detection unit 202 is arranged in the furnace chamber of the heat treatment furnace 101 and is directly connected to the control module 106. The pressure detection unit 202 is responsible for detecting the pressure value in the furnace chamber in real time. Through the built-in pressure sensor, it can keenly sense the change of the pressure in the furnace chamber, and quickly send the detected accurate pressure value to the control module 106, so that the control module 106 can timely understand the pressure condition in the furnace chamber, so as to take corresponding control measures when the pressure is abnormal, and ensure that the heat treatment process is carried out under safe and stable pressure conditions. For example, if the pressure exceeds the preset safety upper limit, the control module 106 can adjust related equipment, such as an exhaust device, to reduce the pressure in the furnace chamber to prevent the occurrence of dangerous situations.

[0034] The temperature detection unit 201 is also arranged in the furnace chamber of the heat treatment furnace 101 and is connected to the control module 106. The temperature detection unit 201 is equipped with a temperature sensor for accurately detecting the temperature value in the furnace chamber. During the heat treatment process, the change of temperature has a very important influence on the performance of the material. The temperature detection unit 201 will continuously monitor the temperature in the furnace chamber and transmit the real-time temperature value to the control module 106 in time. The control module 106 compares and analyzes the received temperature data with the preset temperature curve, and then adjusts the power or other control parameters of the heating element accordingly to ensure that the temperature in the furnace chamber always meets the requirements of the heat treatment process. For example, when it is detected that the temperature is lower than the set value, the control module 106 will increase the heating power to make the temperature return to the ideal range.

[0035] It can be concluded from the above that, by introducing the pressure detection unit 202 and the temperature detection unit 201, this embodiment can obtain the pressure value and temperature value in the furnace chamber in real time and accurately, providing a solid data basis for accurately controlling the heat treatment process. It not only enhances the stability and reliability of the system, but also ensures that the heat treatment parameters are strictly up to standard, thereby significantly improving product quality and production efficiency. At the same time, the intelligent detection and feedback mechanism further simplifies the operation process, reduces human intervention errors, and promotes the modernization of production management.

[0036] In one embodiment of the present disclosure, reference Figure 2 , the control module 106 includes a temperature control unit 301 and a pressure control unit 302; The temperature control unit 301 and the pressure control unit 302 are both connected to the heat treatment furnace 101; The temperature control unit 301 is used to control the temperature of the heat treatment furnace 101 , and the pressure control unit 302 is used to control the pressure of the heat treatment furnace 101 .

[0037] In this embodiment, the temperature control unit 301 is directly connected to the heat treatment furnace 101 and is responsible for accurately controlling the temperature in the chamber of the heat treatment furnace 101. The control module 106 receives real-time temperature data from the temperature detection unit 201 and compares and analyzes it with a preset ideal temperature curve or set value, and the temperature control unit 301 can make a corresponding decision.

[0038] For example, if the current temperature is lower than the set value, the temperature control unit 301 will issue an instruction to increase the heating power to increase the temperature in the heat treatment furnace 101 chamber; if the temperature is too high, the temperature control unit 301 will reduce the heating power or start the cooling device accordingly to ensure that the temperature in the furnace chamber is always maintained within the range that meets the process requirements.

[0039] The pressure control unit 302 is also connected to the heat treatment furnace 101 and is responsible for effectively controlling the pressure in the heat treatment furnace 101. After the control module 106 receives the pressure data from the pressure detection unit 202, the pressure control unit 302 will compare it with the preset safety pressure range. If the pressure exceeds the normal range, such as the pressure is too high, the exhaust device will be controlled to open to release the excess gas in the furnace chamber and reduce the pressure; conversely, if the pressure is too low, the air intake device will be adjusted to increase the amount of gas in the furnace chamber to keep the pressure stable.

[0040] For example, when a certain metal is annealed, the temperature control unit 301 strictly controls the heating and cooling process according to the temperature curve required by the annealing process, while the pressure control unit 302 ensures that the pressure in the furnace chamber is always at an appropriate level to avoid metal oxidation or other adverse phenomena, and ultimately the treated metal obtains ideal performance.

[0041] It can be concluded from the above that the temperature control unit 301 and the pressure control unit 302 built into the control module 106 directly act on the heat treatment furnace 101, realize the precise control of the temperature and pressure in the furnace chamber, ensure the strict compliance of the heat treatment process parameters, and effectively avoid the adverse effects of parameter fluctuations on product quality. At the same time, the coordinated work of the temperature control unit 301 and the pressure control unit 302 improves the controllability and stability of the production process, reduces the defective rate, and further improves production efficiency and economic benefits.

[0042] In one embodiment of the present disclosure, reference Figure 2 , an automatic control system for a heat treatment device further includes a fault detection module 107 and an alarm module 108; The fault detection module 107 is connected to the heat treatment furnace 101 and the control module 106 respectively, and is used to send fault information to the control module 106 when it is detected that the heat treatment furnace 101 is in a fault state; The control module 106 is connected to the alarm module 108 and is used to send an alarm signal to the alarm module 108 when a failure of the heat treatment furnace 101 is detected. The alarm signal is used to instruct the alarm module 108 to issue an alarm.

[0043] In this embodiment, the fault detection module 107 can continuously monitor the operating state of the heat treatment furnace 101. By collecting and analyzing data from various key parts of the heat treatment furnace 101, such as temperature, pressure, equipment operating state, etc., it is determined whether there is a fault. Once it is detected that the heat treatment furnace 101 is in a fault state, such as abnormally high temperature and uncontrollable, pressure exceeding the safety range, key components stopping operation, etc., the fault detection module 107 will immediately send detailed fault information to the control module 106.

[0044] The control module 106 will respond quickly after receiving the fault information from the fault detection module 107. The control module 106 is connected to the alarm module 108, and sends a specific alarm signal to the alarm module 108 when confirming that the heat treatment furnace 101 has a fault.

[0045] After receiving the alarm signal, the alarm module 108 will take corresponding alarm methods to attract the attention of the operator. The alarm methods include but are not limited to sound alarms (such as sirens and buzzers), flashing lights (such as red warning lights), pop-up alarm prompts on the display screen, etc., which can ensure that the operator can know the fault situation in time and take measures quickly, such as emergency shutdown and maintenance, to avoid further expansion of the fault and minimize the losses caused.

[0046] For example, if the heating element of the heat treatment furnace 101 suddenly short-circuits, causing the temperature to run out of control, the fault detection module 107 will quickly capture this abnormality and transmit the fault information to the control module 106. The control module 106 then sends an alarm signal to the alarm module 108, which prompts the operator through a loud siren and a flashing red light, so that the operator can take emergency shutdown measures as soon as possible to prevent damage to the materials in the furnace cavity and the occurrence of safety accidents.

[0047] It can be concluded from the above that this embodiment can timely detect and respond to the failure of the heat treatment device by integrating the fault detection module 107 and the alarm module 108, and effectively prevent the expansion of the fault by sending the fault information to the control module 106 and triggering the alarm signal, thereby ensuring production safety. Therefore, this embodiment not only improves the diagnosis and maintenance capabilities of the system, but also significantly shortens the fault response time, ensures the continuous and stable operation of the production line, and provides a strong guarantee for safe production and efficient operation.

[0048] In one embodiment of the present disclosure, reference Figure 2 , an automatic control system for a heat treatment device further includes a human-computer interaction module 110 and a communication module 109; The control module 106 is connected to the human-computer interaction module 110 via the communication module 109 .

[0049] In this embodiment, through the human-computer interaction module 110, the operator can conveniently input various instructions and parameters, such as setting the process requirements of the heat treatment, adjusting the control range of temperature and pressure, selecting different working modes, etc. At the same time, the human-computer interaction module 110 can also display important information such as the operating status of the system, the processing progress, the detected temperature and pressure data in real time, so that the operator can have a clear and intuitive understanding of the entire heat treatment process.

[0050] The communication module 109 is responsible for establishing an effective data transmission channel between the control module 106 and the human-computer interaction module 110, and also ensures that the control module 106 can accurately and quickly transmit the real-time data of the system to the human-computer interaction module 110, and can also promptly transmit the instructions entered by the operator on the human-computer interaction module 110 to the control module 106.

[0051] For example, the operator inputs a new temperature setting value on the interface of the human-machine interaction module 110, and this instruction is transmitted to the control module 106 through the communication module 109. After receiving the instruction, the control module 106 will adjust the temperature control strategy accordingly, and feed back the adjusted temperature data to the human-machine interaction module 110 through the communication module 109 for display.

[0052] Exemplarily, when the system detects a potential failure risk, the control module 106 will send relevant warning information to the human-computer interaction module 110 through the communication module 109 to remind the operator to take preventive measures in time.

[0053] It can be concluded from the above that this embodiment realizes the friendliness of the operation interface and the convenience of remote monitoring of the system by introducing the human-computer interaction module 110 and the communication module 109. The operator can intuitively operate through the human-computer interaction module 110 to improve work efficiency; and the introduction of the communication module 109 supports remote data interaction and command transmission, which enhances the flexibility and scalability of the system. Therefore, this embodiment realizes the remote monitoring and flexible control of the heat treatment device by the operator. Even if the operator is not at the equipment site, he can understand the system status through the human-computer interaction module 110 and make necessary operational adjustments.

[0054] In one embodiment of the present disclosure, reference Figure 2 , the working parameters include temperature and pressure values; Controlling the conveying speed of the conveying module 102 according to the working parameters and the material position includes: Determine a first weight according to the temperature value and the standard temperature value, where the standard temperature value is an ideal working temperature value corresponding to the material; The second weight is determined according to the pressure value and the standard pressure value, where the standard pressure value is the ideal working pressure value corresponding to the material; Determine the target speed according to the material position; The conveying speed of the conveying module 102 is calculated according to the first weight, the second weight, and the target speed amount.

[0055] In this embodiment, first, this embodiment will compare the detected real-time temperature value with the ideal working temperature value (i.e., standard temperature value) corresponding to the material, and determine the first weight accordingly. If the current temperature value is close to or equal to the standard temperature value, it means that the temperature condition is relatively ideal, and the first weight will be higher; on the contrary, if the temperature value deviates greatly from the standard temperature value, the first weight will be relatively low.

[0056] Similarly, the real-time pressure value is compared with the ideal working pressure value (standard pressure value) corresponding to the material to determine the second weight. The closer the pressure value is to the standard pressure value, the higher the second weight; the greater the deviation, the lower the second weight.

[0057] Then, the target speed is determined according to the position of the material on the conveying module 102. For example, it is calculated according to factors such as the distance of the material from the entrance of the heat treatment furnace 101 and the current processing progress in the furnace.

[0058] Finally, the first weight, the second weight and the target speed are comprehensively considered to calculate the conveying speed of the conveying module 102. The specific calculation method may be through weighted average or other complex mathematical models.

[0059] For example, if the current temperature and pressure values ​​are very close to the standard values, the first weight and the second weight are both high, then when calculating the conveying speed in combination with the target speed, the conveying speed will tend to be maintained or appropriately increased to ensure efficient production. However, if the temperature or pressure deviates greatly from the standard value, the weight is reduced, and the calculated conveying speed will be slowed down accordingly to wait for the temperature and pressure to be adjusted to the appropriate range to ensure that the material is heat treated under ideal conditions.

[0060] It can be concluded from the above that this embodiment significantly improves the accuracy and efficiency of material processing by controlling the conveying speed of the conveying module 102 using the above method. By dynamically adjusting the deviation between the actual working parameters based on temperature and pressure and the standard values, the weight is calculated in real time to ensure that the conveying speed is highly matched with the current state of the material. At the same time, combined with the consideration of the material position, the precise control of the conveying speed is achieved, which not only avoids material damage or inefficiency caused by improper speed, but also ensures the continuity and stability of the production process.

[0061] In one embodiment of the present disclosure, reference Figure 2 , calculating the conveying speed of the conveying module 102 according to the first weight, the second weight and the target speed, including: The conveying speed of the conveying module 102 is calculated using the first formula: The first formula includes:

[0062] in, Indicates the conveying speed, Indicates the standard conveying speed, represents the first weight, represents the second weight, Indicates the target speed amount.

[0063] In this embodiment, It represents the actual conveying speed of the conveying module 102 obtained by final calculation, taking into account the influence of various factors. It represents the standard conveying speed, which is a reference value, that is, the default operating speed of the conveying module 102 when there is no influence of other factors. It is determined by comparing the temperature value with the standard temperature value. Based on the comparison between the pressure value and the standard pressure value. Indicates the target speed, which is the speed adjustment amount determined according to the material position.

[0064] The first weight is calculated using the third formula: The third formula includes:

[0065] in, Indicates the temperature value, Indicates standard temperature value.

[0066] The second weight is calculated using the fourth formula: The fourth formula includes:

[0067] in, Indicates the pressure value. Indicates pressure and temperature values.

[0068] The target speed is calculated using the fifth formula: The fifth formula includes:

[0069] in, Indicates the conveyor belt length, Indicates the material location, Indicates standard time.

[0070] Indicates the distance from the initial position of the conveyor belt to the current position of the material. Indicates the distance from the material to the heat treatment furnace 101.

[0071] For example, when the temperature value is less than the standard temperature value, the first weight value is negative, indicating that deceleration is required; when the temperature value is greater than or equal to the standard temperature value, the first weight value is positive, indicating that acceleration is required. When the pressure value is less than the standard pressure value, the second weight is negative, indicating that deceleration is required; when the pressure value is greater than or equal to the standard pressure value, the second weight is positive, indicating that acceleration is required. If the temperature value is less than the standard temperature value and the pressure value is greater than or equal to the standard pressure value, whether acceleration or deceleration is required is determined based on the specific calculation results.

[0072] It can be concluded from the above that this embodiment significantly improves the speed adjustment flexibility and accuracy of the conveying module 102 by adopting the above calculation method. Therefore, the dynamic weighted adjustment mechanism not only optimizes production efficiency, but also reduces material loss or equipment wear that may be caused by speed mismatch, thereby achieving high efficiency and stability in the conveying process.

[0073] In one embodiment of the present disclosure, reference Figure 2 , material information includes multiple types of materials, size information of each type of material, and material information of each type of material; The working mode of the heat treatment furnace 101 is determined according to the material information of the material, including: Calculate the working mode selection value based on multiple types of materials, size information of each type of materials, and material information of each type of materials; The operation mode of the heat treatment furnace 101 is determined according to the mode selection value.

[0074] In this embodiment, the material information includes multiple types of materials, size information of each type of material, and material information. First, this embodiment calculates the working mode selection value based on the detailed material information.

[0075] When calculating the operating mode selection value, many factors are taken into consideration. For example, different types of materials have different thermal treatment requirements, some materials require higher temperatures and longer processing times, while others require special pressure environments or cooling methods.

[0076] The size of the material is also critical. Larger materials require slower heating rates and longer holding times to ensure that they achieve the desired heat treatment effect both inside and outside.

[0077] Material information is equally important. Different materials have different thermal conductivity, phase change temperature and chemical properties, which will affect the parameter settings of heat treatment.

[0078] Through calculation rules, the categories of multiple types of materials, size information of each type of material, and material information are integrated and analyzed, so as to obtain a working mode selection value that can reflect the requirements of the material characteristics on the working mode of the heat treatment furnace 101.

[0079] Then, the specific working mode of the heat treatment furnace 101 is determined according to the working mode selection value obtained by calculation. The working mode may include different combinations of parameters in terms of temperature curves, heating time, holding time, cooling speed, etc.

[0080] For example, if the material is high-hardness alloy steel and has a large size, the calculated working mode selection value will correspond to a working mode of high temperature, long-time heating, slow cooling, and controlled specific pressure. If the material is aluminum alloy and has a small size, the working mode selection will cause the system to select a working mode of relatively low temperature, short-time heating, and fast cooling.

[0081] It can be concluded from the above that by comprehensively considering the size and material information of multiple types of materials, accurately calculating and determining the working mode of the heat treatment device, the pertinence and efficiency of the heat treatment are significantly improved. This embodiment ensures that the heat treatment process can accurately match the characteristic requirements of different materials, avoiding the waste of resources or insufficient processing caused by the traditional one-size-fits-all model.

[0082] In one embodiment of the present disclosure, reference Figure 2 , the working modes include annealing mode, quenching mode and tempering mode; The operating mode of the heat treatment furnace 101 is determined according to the mode selection value, including: If the mode selection value is less than the first preset value, the heat treatment furnace 101 is controlled to be in the annealing mode; If the mode selection value is greater than or equal to the first preset value and less than or equal to the second preset value, the heat treatment furnace 101 is controlled to be in the quenching mode; If the mode selection value is greater than the second preset value, the heat treatment furnace 101 is controlled to be in the tempering mode; The first preset value is smaller than the second preset value.

[0083] In this embodiment, the working modes are clearly divided into annealing mode, quenching mode and tempering mode, and the working mode is determined based on the comparison between the calculated mode selection value and the preset value.

[0084] First, there are two preset values, ie, a first preset value and a second preset value, and the first preset value is smaller than the second preset value.

[0085] When the calculated mode selection value is less than the first preset value, the system controls the heat treatment furnace 101 to be in the annealing mode. The annealing mode is generally used to reduce the hardness of the material, improve its cutting performance, eliminate internal stress, etc. If the mode selection value corresponding to the material characteristics and processing requirements is small, it indicates that the material is more suitable for annealing to achieve the desired performance improvement.

[0086] If the mode selection value is greater than or equal to the first preset value and less than or equal to the second preset value, the heat treatment furnace 101 will be controlled to be in the quenching mode. Quenching is to greatly improve the hardness and wear resistance of the material, but it will also cause greater internal stress inside the material. At this time, the characteristics and processing requirements of the material require it to undergo a quenching process to obtain specific properties.

[0087] When the mode selection value is greater than the second preset value, the heat treatment furnace 101 is in the tempering mode. Tempering is generally performed after quenching, the purpose of which is to reduce the internal stress generated by quenching, improve the toughness and plasticity of the material, and make the performance of the material more stable and applicable. When the mode selection value is large, the material needs to be tempered to further optimize its performance.

[0088] For example, assuming that the first preset value is 30 and the second preset value is 60, if the calculated mode selection value of a certain material is 20, the heat treatment furnace 101 will use the annealing mode. If the mode selection value is 50, the quenching mode will be used. If the mode selection value reaches 70, the tempering mode will be used.

[0089] From the above, it can be concluded that this embodiment finely divides the working mode of the heat treatment device by setting a specific preset value range. This strategy greatly enhances the flexibility and accuracy of heat treatment, and can automatically select the most suitable treatment method according to the characteristics of the material, which not only ensures the treatment effect but also optimizes energy consumption.

[0090] In one embodiment of the present disclosure, reference Figure 2 , calculate the working mode selection value according to multiple types of materials, the size information of each type of materials and the material information of each type of materials, including: Calculate the working mode selection value using the second formula; The second formula includes:

[0091] in, Indicates the type and quantity of materials. Indicates Kind of materials, Indicates The hardness of the material, Indicates The main chemical composition content of the material, Indicates The size of the material, Indicates The weight of the material, Indicates The performance requirements of the materials Indicates The material of the material, is a constant, Indicates The weight of the hardness of the material, Indicates The weight of the main chemical component content of the material, Indicates The weight of the material size, Indicates The weight of the material, Indicates The weight of the material performance requirements, Indicates The weight of the material.

[0092] In this embodiment, if the mode selection value If the temperature is less than the first preset value, the heat treatment furnace 101 is controlled to be in the annealing mode. The reasons for selecting the working mode include but are not limited to: First, if the calculated If the value is less than the first preset value, it means that the initial hardness of the material is higher than the first hardness value, and annealing is needed to reduce the hardness, which is beneficial to subsequent processing. During the annealing process, the crystal structure inside the material will change, and the arrangement of atoms will be more regular, thereby reducing the hardness of the material and improving its toughness and ductility. Among them, the first hardness value can be adjusted dynamically.

[0093] second, If the value is less than the first preset value, it means that the internal stress of the material is greater than the first stress value. Annealing can eliminate or reduce internal stress by heating and slowly cooling the atoms inside the material so that they have enough time to rearrange themselves. This is very important to prevent deformation or cracking of the material during subsequent processing or use. Among them, the first stress value can be adjusted dynamically.

[0094] If the mode selection value If the value is greater than or equal to the first preset value and less than or equal to the second preset value, the heat treatment furnace 101 is controlled to be in the quenching mode. The reasons for selecting the working mode include but are not limited to: First, quenching is a heat treatment method that can significantly improve the hardness and strength of materials. Through rapid cooling, the material's structure changes to form hard structures such as martensite, thereby greatly improving the mechanical properties of the material. When the value is greater than or equal to the first preset value and less than or equal to the second preset value, the material needs to be less than or equal to the first hardness value and greater than or equal to the second hardness value to meet specific usage requirements. For example, for some parts that need to withstand large loads, wear or impact, such as mechanical parts, cutting tools, etc., higher hardness and strength are crucial. Selecting the quenching mode can enable the material to obtain performance that meets the requirements of the above application scenarios. Among them, the second hardness value can be adjusted dynamically.

[0095] Second, some materials in this Within the value range, quenching can better exert its performance advantages. For example, some alloy steels can obtain excellent comprehensive mechanical properties after proper quenching treatment. At the same time, the chemical composition of the material will also affect the quenching effect. A specific combination of elements may make the material form a more stable organizational structure during the quenching process.

[0096] If the mode selection value If the temperature is greater than the second preset value, the heat treatment furnace 101 is controlled to be in the tempering mode. The reasons for selecting the working mode include but are not limited to: First, reduce brittleness. If the value is greater than the second preset value, it means that the hardness of the material is less than the second hardness value, that is, the material is relatively brittle. Tempering can reduce the brittleness of the material, improve its toughness and ductility, and make the material have better impact resistance and fracture resistance while maintaining a certain hardness and strength, so as to meet the safety and reliability requirements in actual use.

[0097] Second, in this Under certain conditions, the material needs to achieve a balance between multiple performance indicators such as hardness, strength, and toughness. Tempering can fine-tune the performance of the material. By controlling the tempering temperature and time, the material's organizational structure can be changed to varying degrees, thereby achieving a comprehensive optimization of hardness, strength, and toughness to adapt to various complex working environments and usage conditions.

[0098] The performance requirements of materials may include physical properties (such as density, melting point and thermal conductivity), mechanical properties (such as strength, hardness and toughness), and chemical properties (such as corrosion resistance and oxidation resistance).

[0099] For example, suppose there are three kinds of materials, namely .

[0100] Material 1: Hardness ; Chemical composition content ;size ;weight ;Performance requirements (Assumption 1 represents high hardness requirement); Material (Assuming 1 represents a certain material).

[0101] Material 2: Hardness ; Chemical composition content ;size ;weight ;Performance requirements (Assumption 2 represents good toughness requirements); Material .

[0102] Material 3: Hardness ; Chemical composition content ;size ;weight ;Performance requirements (Assumption 3 represents high strength demand); Material .

[0103] Assume that the weight coefficients of each material are: Material 1: , , , , , ; Item 2: , , , , , ; Material 3: , , , , , ; constant .

[0104] The calculation is as follows:

[0105] Assuming that it is set in advance, when When selecting annealing mode, When selecting the quenching mode, In this case, select the tempering mode.

[0106] It can be concluded from the above that this embodiment not only optimizes the heat treatment effect, but also improves production efficiency and consistency of material properties by finely dividing the three working modes of annealing mode, quenching mode, and tempering mode, and flexibly switching according to preset values. The above working mode setting strategy significantly improves the flexibility and adaptability of the heat treatment device.
