[0002] Intelligent temperature control systems are temperature regulation solutions based on sensor technology, automatic control algorithms, and the Internet of Things (IoT), widely used in homes, industries, and agriculture. The core of an intelligent temperature control system is to collect ambient temperature data in real time using temperature sensors. This data is then processed by a controller (such as a PLC, microcontroller, or smart thermostat), and algorithms are used to adjust actuators (such as air conditioners, heaters, and ventilation equipment) to achieve the target temperature. However, traditional intelligent temperature control systems often experience large temperature differences during operation, requiring significant energy consumption and increasing operating costs.

[0003] To address the issue of high energy consumption, a certain intelligent temperature control system on the market adopts a variable frequency control design and has a certain market share.

The system includes a temperature sensor installed in the working area of ​​the test chamber. The output of the temperature sensor is connected to the input of a PLC. The PLC's cooling output controls a refrigeration system, and its heating output controls a heater. The heater and the evaporator in the refrigeration system are installed within the temperature control zone of the test chamber. The significant advantages are: fewer system loops, simple structure, efficient resource utilization, low energy consumption, fast adjustment time, simple operation, and low equipment load – making it an intelligent high and low temperature test chamber temperature control system.

[0005] Chinese invention patent application CN118295477A discloses an intelligent dynamic temperature and humidity control system, including a first control subsystem, a second control subsystem, and a third control subsystem.

The AC fan in the first control system, the DC brushless fan in the second control system, and the fan in the third control system are all used to receive commands and operate for temperature and humidity control. The analog signal electric regulating valve in the first, second, and third control subsystems is used to control the analog regulating valve to infinitely regulate the chilled water flow. This system enables better and more comprehensive intelligent dynamic temperature and humidity control.

[0006] While the aforementioned technologies have addressed the issue of high energy consumption due to large temperature differences during temperature balancing in intelligent temperature control systems to some extent, they still have limitations in metallurgical applications. Specifically, some complex metallurgical processes often require coordinated temperature control of multiple zones to ensure metal smelting quality and production efficiency. However, existing intelligent temperature control systems generally lack the ability to coordinate temperature control across multiple zones, thus failing to be effectively applied to complex metallurgical processes and unable to effectively guarantee the stability of metallurgical product quality and production efficiency. Summary of the Invention

[0014] An insulating strip is fixedly connected to the lower end of the dynamic sensing block. A long sliding hole that matches the insulating strip is opened at the lower end of the step sensing cylinder. The lower end of the insulating strip extends to the outside of the step sensing cylinder through the long sliding hole and is fixedly connected to the slider of the sliding rheostat in the sliding rheostat circuit of the composite circuit.

[0015] As a supplement to this application, temperature change imaging components are fixedly connected to both ends of the dynamic sensing block, and the end of the temperature change imaging component away from the dynamic sensing block is fixedly connected to the electric beam connector.

On the one hand, by monitoring and controlling the temperature of each zone, the temperature control accuracy of the temperature control device can be effectively improved, making the device suitable for complex metallurgical processes and ensuring metallurgical quality and production efficiency. On the other hand, by dynamically controlling the temperature difference of adjacent zones, the accuracy and effectiveness of overall metallurgical temperature control can be effectively guaranteed, improving the intelligence level of the temperature control process, ensuring low temperature fluctuations in the metallurgical process, reducing the metallurgical defect rate, reducing temperature control energy consumption, and effectively promoting the economic efficiency of the temperature control device in complex metallurgical processes.

Detailed Implementation

[0035] The three embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0036] Implementation method 1:

[0037] Figure 10 The present invention illustrates an intelligent temperature control system for metallurgy, including a metallurgical furnace 9, a temperature control device body 1 that cooperates with the metallurgical furnace 9, and thermal resistors 3 installed in each smelting zone of the metallurgical furnace 9. The thermal resistors 3 can be distributed and installed at key locations in each smelting zone of the metallurgical furnace 9, such as the furnace wall, furnace core, and discharge port, and can collect temperature data in each smelting zone of the metallurgical furnace 9 in real time. The temperature control device body 1 is connected to multiple temperature control pipes 2 that are respectively installed in each smelting zone of the metallurgical furnace 9, and electromagnetic flow valves 21 are fixedly installed on the temperature control pipes 2.

[0038] The thermal resistor 3 uses a high-precision thermocouple sensor or thermal resistance sensor, which has the characteristics of fast response speed and high measurement accuracy. It can accurately measure the temperature in the range of -200℃ to 1800℃, with the error controlled within ±0.5℃.

[0039] A smart temperature control box that works in conjunction with the temperature control device body 1 is fixedly installed on the metallurgical furnace 9. The smart temperature control box contains a smart temperature control processing unit. The input end of the smart temperature control processing unit is connected to a regional temperature monitoring unit, and the output end of the smart temperature control processing unit is connected to a temperature control unit.

[0040] The intelligent temperature control processing unit uses a high-performance microprocessor to receive data from the regional temperature monitoring unit. On the one hand, it performs preprocessing such as filtering and amplification on the data to remove noise interference. On the other hand, based on the preset metallurgical process temperature curve, it uses advanced fuzzy control algorithm and PID control algorithm to analyze and calculate the temperature data, calculate the deviation and rate of change between the current temperature and the target temperature, and then generate control commands to send to the temperature control unit.

[0041] The input terminal of the zone temperature monitoring unit is connected to the signal of the thermal resistor 3, and the output terminal of the temperature control unit is connected to the signal of the temperature control device body 1 and the electromagnetic flow valve 21 respectively. Through the cooperation of the thermal resistor 3, the zone temperature monitoring unit, the intelligent temperature control processing unit and the temperature control unit, the problems of inaccurate and inefficient multi-zone temperature control in existing metallurgical processes can be effectively solved. This enables intelligent, accurate and stable control of the temperature in each zone during the metallurgical process, improves the quality of metallurgical products, effectively reduces the energy consumption of the metallurgical furnace 9 and reduces the production cost of the metallurgical process.

[0042] The temperature control unit 1 also includes an intelligent power regulator, a heating element, and a cooling device. The temperature control unit transmits control commands to the intelligent power regulator, which adjusts the heating output by changing the input power of the heating element. When the temperature is below the target value, the heating power is increased; when the temperature is above the target value, the heating power is decreased. The cooling device uses a combination of air cooling and water cooling. It activates when the temperature is too high to quickly reduce the temperature inside the furnace. Air cooling uses a high-power fan to accelerate airflow and dissipate heat, while water cooling uses circulating water pipes to remove heat, ensuring that the temperature quickly and stably approaches the target value.

[0043] Figure 10 The input terminal of the intelligent temperature control processing unit is also connected to a metallurgical parameter setting unit and a metallurgical command acquisition unit. The input terminals of the metallurgical parameter setting unit and the metallurgical command acquisition unit are both connected to the data input signal of the intelligent temperature control box.

[0044] The data input of the intelligent temperature control box is connected to the touch screen. Operators can input metallurgical process parameters, such as target temperature, heating rate, and holding time, into the metallurgical parameter setting unit on this interface, so as to conveniently and flexibly set temperature control schemes. Operators can also input commands about controlling the metallurgical furnace 9 into the metallurgical command acquisition unit through the touch screen, such as start-stop control and parameter adjustment control commands.

[0045] The output of the intelligent temperature control processing unit is also connected to a metallurgical data output unit and an abnormality warning unit. The outputs of both the metallurgical data output unit and the abnormality warning unit are connected to the data transmission port signal of the intelligent temperature control box, and the output of the abnormality warning unit is also connected to the warning signal installed on the metallurgical furnace 9.

[0046] The intelligent temperature control box's data transmission port connects to a touchscreen display. The metallurgical data output unit can display real-time temperature data, current temperature curves, and equipment operating status at various monitoring points within the furnace via the touchscreen, allowing operators to intuitively understand the equipment's working condition. The abnormality warning unit and alarm work together to promptly issue audible and visual alarm signals when the temperature exceeds the set safe range or when equipment malfunctions, reminding operators to take appropriate measures.

[0047] The data input and data transmission ports of the intelligent temperature control box can also transmit and interact with the factory's host computer system or remote monitoring center through various communication methods such as Wi-Fi, Bluetooth, and Ethernet; enabling remote monitoring and operation. Managers can view temperature data and equipment operating status in the metallurgical process anytime and anywhere through mobile phones, computers, and other terminal devices. When necessary, they can also remotely adjust control parameters, improving the convenience and intelligence of production management.

[0048] By utilizing the thermal resistor 3 and intelligent temperature control processing unit, precise temperature control is achieved, effectively controlling metallurgical temperatures within ±1℃, thus improving metal product quality and reducing defect rates. It also offers energy savings, intelligently adjusting heating and cooling based on real-time temperature to avoid energy waste, reducing energy consumption by 15%–25% compared to traditional temperature control methods. Furthermore, it effectively improves metallurgical efficiency; automated intelligent control reduces manual intervention, shortens the metallurgical cycle, and increases production efficiency by over 20%. Additionally, it provides remote monitoring capabilities, supporting remote operation via various communication methods, facilitating production management and enhancing factory intelligence.

[0049] Figure 10 The diagram shows the RTD 3 installed on the metallurgical furnace 9 according to the designed position, with the RTD 3 installed at a 45° angle to ensure a secure installation and good contact for accurate temperature measurement. The wiring between each unit is connected to ensure stable signal transmission. The touchscreen display is installed in a location convenient for operators to observe and operate.

[0050] The operator inputs the required parameters for the metallurgical process into the metallurgical parameter setting unit on the touch screen interface, such as a target temperature of 1200℃, a heating rate of 5℃ / min, and a holding time of 30min. The intelligent temperature control processing unit generates the corresponding temperature control curve based on the data transmitted from the metallurgical parameter setting unit. Subsequently, the intelligent temperature control processing unit starts the metallurgical furnace 9 and the temperature control device body 1 based on the operator's command data transmitted from the metallurgical command acquisition unit. The thermal resistor 3 and the zone temperature monitoring unit collect the furnace temperature data in real time and transmit it to the intelligent temperature control processing unit. The intelligent temperature control processing unit analyzes the received data and calculates the deviation by comparing it with the preset temperature curve.

[0051] When the current temperature is determined to be lower than the target value and the deviation reaches the set adjustment threshold, the intelligent temperature control processing unit sends an instruction to the temperature control unit, which then controls the intelligent power regulator in the temperature control device body 1 and the opening status of the electromagnetic flow valve 21. The intelligent power regulator increases the power of the heating element and begins to heat up. When the temperature approaches the target value, the heating power is finely adjusted through an algorithm to stabilize the temperature within the range of ±1℃ of the target value.

[0052] When the current temperature is determined to be higher than the target value, the intelligent temperature control processing unit sends a command to the temperature control unit, which then controls the cooling device in the temperature control device body 1 to cool down the device.

[0053] Furthermore, during the operation of the metallurgical furnace 9 and the temperature control device body 1, the intelligent temperature control processing unit can also display temperature and other information in real time through the metallurgical data output unit via the touch screen, and transmit the data to the remote monitoring center via remote communication. When there is a temperature abnormality, the abnormal temperature data is displayed on the touch screen through the abnormality warning unit, and transmitted to the remote monitoring center via remote communication. The abnormality warning unit also activates the alarm, generating an audible and visual alarm to remind the operator to check and handle the abnormality.

[0054] After the metallurgical furnace 9 and the temperature control device body 1 have been in continuous use, the operator needs to regularly inspect and maintain them, such as cleaning the thermal resistor 3 and checking the wiring connections of each unit.

[0055] The second implementation method:

[0056] Figure 1 - Figure 9The present invention illustrates an intelligent temperature control system for metallurgy, comprising a metallurgical furnace 9, a temperature control device body 1 that cooperates with the metallurgical furnace 9, and thermal resistors 3 installed on each smelting zone of the metallurgical furnace 9. Multiple temperature difference dynamic sensing components 4 corresponding to the thermal resistors 3 are fixedly installed on the outer end of the metallurgical furnace 9. Multiple temperature control pipes 2 are connected to the temperature control device body 1 and are respectively installed on each smelting zone of the metallurgical furnace 9. Electromagnetic flow valves 21 are fixedly installed on the temperature control pipes 2 and the electromagnetic flow valves 21 cooperate with the corresponding temperature difference dynamic sensing components 4.

[0057] A smart temperature control box that works in conjunction with the temperature control device body 1 is fixedly installed on the metallurgical furnace 9. The smart temperature control box is equipped with a smart temperature control processing unit. The input end of the smart temperature control processing unit is connected to a zone temperature monitoring unit and a zone temperature difference monitoring unit. The output end of the smart temperature control processing unit is connected to a temperature control unit.

[0058] The input terminal of the zone temperature monitoring unit is connected to the signal of the thermal resistor 3, and the input terminal of the zone temperature difference monitoring unit is connected to the signal of the temperature difference dynamic sensing component 4. The output terminal of the temperature control unit is connected to the signal of the temperature control device body 1 and the electromagnetic flow valve 21 respectively. Through the synergistic effect of the electromagnetic flow valve 21, the thermal resistor 3, the temperature difference dynamic sensing component 4, the intelligent temperature control processing unit, and the zone temperature difference monitoring unit, the dual function of individually controlling the temperature of each zone of the metallurgical furnace 9 and dynamically controlling the temperature difference of adjacent zones can be effectively realized. On the one hand, through the individual monitoring and control of the temperature of each zone, the temperature control accuracy of the temperature control device body 1 can be effectively improved, promoting the application of the temperature control device body 1 to the needs of complex metallurgical processes, ensuring the quality and production efficiency of metallurgy. On the other hand, through the dynamic control of the temperature difference of adjacent zones, the accuracy and effectiveness of the overall metallurgical temperature control can be effectively guaranteed, the intelligence level of the temperature control process can be improved, the low temperature fluctuation in the metallurgical process can be guaranteed, the metallurgical defect rate can be reduced, the temperature control energy consumption can be reduced, and the economic efficiency of the application of the temperature control device body 1 in complex metallurgical processes can be effectively promoted.

[0059] Figure 1 and Figure 9The diagram shows that the thermal resistor 3, the temperature difference dynamic sensing component 4, and the electromagnetic flow valve 21 are electrically connected via a composite circuit 7. The composite circuit 7 is equipped with a sliding rheostat circuit that cooperates with the temperature difference dynamic sensing component 4 and the electromagnetic flow valve 21. The sliding rheostat circuits located at the left and right ends of the temperature difference dynamic sensing component 4 are mirror-image arranged. The output terminals of the two thermal resistors 3 installed in two adjacent smelting zones are respectively connected to the left and right ends of the temperature difference dynamic sensing component 4 located at corresponding positions. The output terminals of the two thermal resistors 3 installed in the first and last smelting zones are respectively connected to the left and right ends of the last temperature difference dynamic sensing component 4. The terminals are connected to form a closed-loop connection between the thermal resistor 3 and the temperature difference dynamic sensing component 4. This enables real-time monitoring of the temperature of each smelting zone, as well as effective monitoring of the temperature difference between two adjacent smelting zones and between the first and last smelting zones. While ensuring temperature uniformity and control effectiveness between two adjacent smelting zones, it also enables precise matching of temperature regulation throughout the entire smelting process. This achieves intelligent, high-precision, and high-stability temperature control, effectively promoting smelting efficiency and quality, reducing energy consumption for temperature control during smelting, and lowering smelting costs.

[0060] The current output terminal of the thermal resistor 3 is connected to the signal of the zone temperature monitoring unit, and is also electrically connected to the temperature difference dynamic sensing component 4 through the composite circuit 7. The specific connection of the thermal resistor 3 and the temperature difference dynamic sensing component 4 is illustrated in the following example: There are 3 smelting zones on the metallurgical furnace 9, and a thermal resistor 3 is installed in each smelting zone. Therefore, the number of temperature difference dynamic sensing components 4 is the same as the number of thermal resistors 3, which is 3.

[0061] The output terminals of the first thermal resistor 3 and the second thermal resistor 3 are respectively connected to the left and right ends of the first temperature difference dynamic sensing component 4 through the composite circuit 7. The first temperature difference dynamic sensing component 4 can monitor the temperature difference data between the first thermal resistor 3 and the second thermal resistor 3 to ensure the temperature balance and the effectiveness of temperature control between two adjacent smelting areas, and avoid the problem of metallurgical quality reduction caused by excessive temperature difference.

[0062] The output terminals of the second and third thermal resistors 3 are respectively connected to the left and right ends of the second temperature difference dynamic sensing component 4 through the composite circuit 7. The second temperature difference dynamic sensing component 4 can monitor the temperature difference data between the second and third thermal resistors 3 to ensure the temperature balance and the effectiveness of temperature control between two adjacent smelting areas, and avoid the problem of metallurgical quality reduction caused by excessive temperature difference.

[0063] The output terminals of the third thermal resistor 3 and the first thermal resistor 3 are respectively connected to the left and right ends of the third temperature difference dynamic sensing component 4 through the composite circuit 7. The third temperature difference dynamic sensing component 4 can monitor the temperature difference data between the third thermal resistor 3 and the first thermal resistor 3 to ensure the accurate matching of the overall metallurgical temperature control and achieve the goal of intelligent, high precision and high stability temperature control.

[0064] Figure 3 - Figure 8 The temperature difference dynamic sensing component 4 includes a stepped sensing cylinder 41 fixedly installed on the metallurgical furnace 9. Both ends of the stepped sensing cylinder 41 are fitted with electric beam connectors 45, and the electric beam connectors 45 are electrically connected to the thermal resistor 3 through the composite circuit 7. A dynamic sensing block 43 is slidably arranged in the middle of the inner wall of the stepped sensing cylinder 41.

[0065] An insulating strip 44 is fixedly connected to the lower end of the dynamic sensing block 43. A long sliding hole 42, matching the insulating strip 44, is provided at the lower end of the step sensing cylinder 41. The lower end of the insulating strip 44 extends through the long sliding hole 42 to the outside of the step sensing cylinder 41 and is fixedly connected to the slider of the sliding rheostat in the sliding rheostat circuit on the composite circuit 7. The insulating strip 44 is also fixed to the sliders of the sliding rheostats in the two sliding rheostats circuits on the left and right sides, causing them to move in the same direction. Since the two sliding rheostats circuits are mirror images, when the insulating strip 44 causes the sliders of the two sliding rheostats to move in the same direction, the resistance of one sliding rheostat circuit increases, while the resistance of the other sliding rheostat circuit decreases. Therefore, the dynamic sensing block 43 can effectively move the insulating strip 44. The different control actions of the electromagnetic flow valves 21 on the two corresponding smelting areas effectively achieve the balanced regulation of the temperature difference between the two corresponding smelting areas. The dynamic sensing block 43 dynamically senses the temperature of the two corresponding smelting areas and works in conjunction with the insulating strip 44 to act on the sliding rheostat in the sliding rheostat circuit. When the temperature difference between the two corresponding smelting areas becomes unbalanced, the resistance value of the sliding rheostat is changed synchronously, which acts on the circuit of the electromagnetic flow valve 21 to control the flow of hot gas in the temperature control pipeline 2. This effectively achieves the automated regulation of the temperature difference between the two corresponding smelting areas. While promoting the intelligence level of the temperature control device 1, it can also effectively promote the regulation and control of the metallurgical temperature in each area, ensure metallurgical quality, and promote the applicability to complex metallurgical processes.

[0066] Figure 3 - Figure 8The dynamic sensing block 43 is shown to have temperature-changing imaging components 5 fixedly connected to both ends. The end of the temperature-changing imaging component 5 furthest from the dynamic sensing block 43 is fixedly connected to the electric beam connector 45. The temperature-changing imaging component 5 includes a magnetically shielding elastic sleeve 51 fixedly installed between the dynamic sensing block 43 and the electric beam connector 45. Electromagnetic repulsion blocks 52 are fixedly connected to the inner walls of the magnetically shielding elastic sleeve 51 via a composite circuit 7 and electrically connected to the thermal resistor 3. An elastic spacer 53 is fixedly connected between the two electromagnetic repulsion blocks 52. A pressure sensing probe is installed inside the magnetically shielding elastic sleeve 51. The input end of the area temperature difference monitoring unit is connected to the pressure sensing probe. The head signal connection, through the composite circuit 7, electrically connects the thermal resistor 3 and the elastic spacer 53, which can effectively realize the real-time display of the temperature of each area, effectively act on the dynamic sensing block 43, realize its dynamic balancing effect on the temperature difference between the two corresponding smelting areas, improve the temperature control accuracy and promote the smelting quality, and can also effectively reduce the energy loss of the temperature control device body 1 when controlling the temperature. In addition, by controlling the flow of the temperature control pipe 2, the temperature in the smelting area can be adjusted within a small range, effectively reducing the temperature fluctuation during the temperature control process, ensuring the stability of the temperature, and promoting the quality of metallurgical products.

[0067] Figure 1 and Figure 2 The input terminal of the intelligent temperature control processing unit is also connected to a metallurgical parameter setting unit and a metallurgical command acquisition unit. The input terminals of the metallurgical parameter setting unit and the metallurgical command acquisition unit are both connected to the data input signal of the intelligent temperature control box.

[0068] The output of the intelligent temperature control processing unit is also connected to a metallurgical data output unit and an abnormality warning unit. The outputs of both the metallurgical data output unit and the abnormality warning unit are connected to the data transmission port of the intelligent temperature control box. The output of the abnormality warning unit is also connected to the warning signal installed on the metallurgical furnace 9. The setting of the metallurgical parameter setting unit and the metallurgical command acquisition unit can effectively promote the intelligence level of the intelligent temperature control processing unit, promote its subsequent temperature regulation, fully ensure the stability and safety of the metallurgical process, and also realize the human-machine interaction through the setting of the metallurgical data output unit and the abnormality warning unit, improve the emergency response efficiency of operators in emergency situations, and ensure the safety of the metallurgical process.

[0069] Figure 1 and Figure 2The output of the intelligent temperature control processing unit is also connected to a current direction adjustment unit. The output of the current direction adjustment unit is connected to the electromagnetic repulsion block 52 via the composite circuit 7. The current direction adjustment unit enables effective control and change of the electromagnetic repulsion or electromagnetic attraction between the two electromagnetic repulsion blocks 52 within the same magnetically shielded elastic sleeve 51. This enables the effective dynamic balancing of the temperature difference dynamic sensing component 4 and the temperature change imaging component 5. It is applicable to two corresponding smelting areas with different temperature gradients and different gradient directions, promoting the applicability of the temperature difference dynamic sensing component 4 and the temperature change imaging component 5, fully ensuring the control of temperature balance in each area, and promoting the applicability of the temperature control device body 1 to complex metallurgical processes.

A pressure acquisition device 8 is fixedly installed on the temperature control pipeline 2 to cooperate with it. The input end of the temperature control pressure monitoring unit is connected to the pressure acquisition device 8. The setting of the temperature control pressure monitoring unit and the pressure acquisition device 8 can fully ensure the safety of the temperature control device 1 during the temperature control process. By sensing the pressure inside the temperature control pipeline 2, the function of the electromagnetic flow valve 21 is verified and feedback is achieved. This ensures the effectiveness of the dynamic temperature difference sensing component 4 and the temperature change imaging component 5 in dynamically regulating the electromagnetic flow valve 21. It can also ensure the safety of the operation of the temperature control pipeline 2 after the electromagnetic flow valve 21 generates regulation, and avoid mechanical damage caused by excessive pressure inside the temperature control pipeline 2.

[0071] Figure 1 - Figure 9The diagram shows a temperature control device 1 applied to a metallurgical furnace 9. Multiple temperature control pipes 2 are used to independently control the temperature of various smelting zones within the furnace 9. When the temperature control device 1 and the metallurgical furnace 9 are started, the intelligent temperature control processing unit, based on the instructions and metallurgical parameter data transmitted by the metallurgical instruction acquisition unit and the metallurgical parameter setting unit, issues control commands to the temperature control unit. This causes the temperature control unit to deliver heat to each zone of the metallurgical furnace 9 through the temperature control pipes 2, raising its internal temperature to meet the required metallurgical temperature. Furthermore, the temperature control unit also controls the electromagnetic flow valve 21. The system is opened to meet the flow requirements of the temperature control pipeline 2 to deliver heat to each smelting area of ​​the metallurgical furnace 9. Then, the thermal resistor 3 collects the temperature of the corresponding smelting area in real time and transmits the temperature data of each smelting area to the intelligent temperature control processing unit through the area temperature monitoring unit. The intelligent temperature processing unit can judge the effectiveness of the temperature control based on the acquired data. If there is a temperature control error, it will continue to control the temperature control device body 1 through the temperature control unit, so that it can effectively and accurately control the temperature in each smelting area of ​​the metallurgical furnace 9 and ensure the quality of smelting.

[0072] During the temperature control process by the intelligent temperature control processing unit, the resistance change generated by the temperature sensing of the thermal resistor 3 can act on the circuit entering the corresponding electromagnetic repulsion block 52 through the composite circuit 7. Therefore, when the resistance of the thermal resistor 3 changes, it can change the magnitude of the current entering the electromagnetic repulsion block 52, thereby changing the electromagnetic force between the two electromagnetic repulsion blocks 52 within the same magnetically shielding elastic sleeve 51. This causes the magnetically shielding elastic sleeve 51 to deform along its length. Since the two magnetically shielding elastic sleeves 51 at both ends of the dynamic sensing block 43 are affected by the resistance values ​​of the thermal resistors 3 in the corresponding two smelting areas, after deformation of one side of the magnetically shielding elastic sleeve 51, the position of the dynamic sensing block 43 within the stepped sensing cylinder 41 changes. This displacement of the dynamic sensing block 43 can effectively display the temperature difference data between the corresponding two smelting areas. The dynamic sensing block 43 drives the insulating strip 44 to move, so that the insulating strip 44 acts on the slider of the sliding rheostat in the sliding rheostat circuit of the composite circuit 7, so that the slider moves in the sliding rheostat, changing the current in the electromagnetic flow valve 21 of the corresponding smelting area of ​​the composite circuit 7, thereby changing the flow rate of the electromagnetic flow valve 21, realizing small-range control of the flow in the temperature control pipeline 2, thereby realizing the dynamic regulation of the temperature difference between the two corresponding smelting areas. At the same time, during the deformation of the magnetic insulating elastic sleeve 51, the pressure sensing probe inside it transmits the internal pressure change data to the area temperature difference monitoring unit. The area temperature difference monitoring unit transmits the data to the intelligent temperature control processing unit, so that the intelligent temperature control processing unit can effectively judge the temperature difference data of the two corresponding smelting areas based on the pressure change data, and judge the accuracy of temperature control of each area.

[0073] When the temperature difference data between the two corresponding smelting areas is in a balanced state, the resistance values ​​of the two corresponding thermal resistors 3 do not change significantly. This allows the electromagnetic repulsion blocks 52 located in the magnetically shielded elastic sleeves 51 on both sides of the dynamic sensing block 43 to achieve dynamic balance. Consequently, the dynamic sensing block 43 will not undergo a large range of displacement or will not undergo any displacement, thus not affecting the current of the composite circuit 7 acting on the electromagnetic flow valve 21. This satisfies the temperature accuracy of each smelting area and the temperature difference balance between each smelting area.

[0074] When a large temperature fluctuation occurs in one of the smelting areas, causing a change in its temperature, the thermal resistor 3 transmits the temperature data to the area temperature monitoring unit. When the intelligent temperature control processing unit determines that the temperature fluctuation is within the controllable range, it does not control the temperature control unit. At the same time, the resistance of the thermal resistor 3 also acts on the electromagnetic repulsion block 52 connected to it through the composite circuit 7, causing a change in magnetic force between the two electromagnetic repulsion blocks 52, which in turn causes the magnetic isolation elastic sleeve 51 to deform. After the magnetic isolation elastic sleeve 51 on the other side deforms, it causes the dynamic sensing block 43 to move within the stepped sensing cylinder 41. The dynamic sensing block 43 causes the insulating strip 44 to move synchronously, which in turn causes the insulating strip 44 to act on the slider of the sliding rheostat in the sliding rheostat circuit of the composite circuit 7, causing the slider to move within the sliding rheostat and change the current magnitude of the electromagnetic flow valve 21 in the corresponding smelting area of ​​the composite circuit 7, thereby changing the flow rate of the corresponding electromagnetic flow valve 21 in the two corresponding smelting areas.

[0075] For example, when a single smelting zone experiences a low temperature, increasing the flow rate of the electromagnetic flow valve 21 within that low-temperature smelting zone promotes heat transfer within the temperature control pipe 2, raising the temperature of the low-temperature smelting zone. Simultaneously, the dynamic sensing block 43, acting on the insulating strip 44, also affects the corresponding smelting zone within that low-temperature zone. This causes the slider of the sliding rheostat in the sliding rheostat circuit of the composite circuit 7 connected to the electromagnetic flow valve 21 in that zone to move in the same direction, reducing the flow rate of the electromagnetic flow valve 21, suppressing heat transfer within the temperature control pipe 2, and thus reducing the temperature difference between the two corresponding smelting zones, maintaining their temperature balance. Furthermore, when the dynamic temperature difference control range is large, the electromagnetic flow valves 21 in the sequentially related zones will undergo synchronous control under the action of the thermal resistor 3 and the temperature difference dynamic sensing component 4, resulting in a more balanced overall smelting zone. The temperature is balanced; subsequently, as the temperature in the low-temperature smelting zone gradually rises and reaches the smelting temperature standard, the resistance of the thermal resistor 3 will act on the corresponding electromagnetic repulsion block 52, causing it to generate an electromagnetic force recovery effect, thereby restoring the position of the dynamic sensing block 43. Then, through the insulating strip 44, it acts on the slider of the sliding rheostat in the sliding rheostat circuit of the composite circuit 7, so that the flow of the electromagnetic flow valve 21 in the two corresponding smelting zones is restored, completing the temperature difference balancing effect of the two corresponding smelting zones. At the same time, the related smelting zones will also generate a synchronous recovery effect, thereby effectively avoiding smelting abnormalities caused by local temperature fluctuations, ensuring smelting quality, promoting temperature control efficiency, reducing smelting temperature fluctuation rate, and effectively reducing the energy consumption of the temperature control device body 1 in the temperature control process, thus reducing smelting costs.

[0076] Furthermore, during the control process, the pressure acquisition unit 8 transmits the pressure data of the temperature-controlled pipeline 2 to the intelligent temperature control processing unit through the temperature control pressure monitoring unit. This allows the intelligent temperature control processing unit to determine the effectiveness of the control effect of the thermal resistor 3 and the temperature difference dynamic sensing component 4 on the electromagnetic flow valve 21 through the composite circuit 7 based on the pressure data in the temperature-controlled pipeline 2. It can also promptly control the temperature through the temperature control unit when the pressure in the temperature-controlled pipeline 2 is too high, preventing the thermal resistor 3 and the temperature difference dynamic sensing component 4 from continuously acting on the electromagnetic flow valve 21 through the composite circuit 7, which could cause excessive pressure in the temperature-controlled pipeline 2, damage the connection points and pipe walls, improve the durability of the temperature-controlled pipeline 2, and reduce heat loss.

[0077] During the process of regulating the electromagnetic flow valve 21 through the composite circuit 7 by the thermal resistor 3 and the temperature difference dynamic sensing component 4, the intelligent temperature control processing unit judges the effectiveness of the small-range temperature regulation based on the temperature data continuously transmitted by the regional temperature monitoring unit. If the regulation is deemed effective, no regulation is performed. If the regulation is deemed ineffective, a regulation command is transmitted to the temperature regulation unit to readjust the temperature. Furthermore, the unit transmits warning data about the small-range temperature regulation to the data transmission port through the abnormality warning unit and activates the alarm to issue a reminder. This allows operators to respond promptly based on the warning data and signals, ensuring the effectiveness of temperature control in the subsequent smelting process. When the intelligent temperature control processing unit determines that the small-range temperature regulation is abnormal, it judges the data transmitted by the regional temperature difference monitoring unit and determines that it is in an abnormal state. The system monitors the pressure changes within the magnetically shielded elastic sleeve 51 at normal data positions to determine whether the problem lies in the composite circuit 7 connecting the thermal resistor 3 and the electromagnetic repulsion block 52, or in the sliding rheostat circuit on the composite circuit 7 connecting the electromagnetic repulsion block 52 and the electromagnetic flow valve 21. If a corresponding pressure change occurs within the magnetically shielded elastic sleeve 51, the composite circuit 7 connecting the thermal resistor 3 and the electromagnetic repulsion block 52 is considered normal, while the sliding rheostat circuit on the composite circuit 7 connecting the electromagnetic repulsion block 52 and the electromagnetic flow valve 21 may be malfunctioning. If no corresponding pressure change occurs within the magnetically shielded elastic sleeve 51, the composite circuit 7 connecting the thermal resistor 3 and the electromagnetic repulsion block 52 may be malfunctioning, and the intelligent temperature control processing unit will transmit the corresponding abnormal data to the data transmission port through the abnormality warning unit.

[0078] Meanwhile, during the operation of the temperature control device 1, the intelligent temperature control processing unit also transmits its temperature control data for each smelting area, as well as relevant data on temperature changes, to the data transmission port through the metallurgical data output unit, so as to ensure that the operator can intuitively observe the temperature changes of the metallurgical furnace 9 and ensure the safety and effectiveness of the metallurgical process.

[0079] Furthermore, after the intelligent temperature control processing unit receives the data transmitted by the metallurgical parameter setting unit and determines the temperature control standard of each area, it uses the current direction adjustment unit to change the direction of the current acting on the composite circuit 7 connected to the thermal resistor 3 and the electromagnetic repulsion block 52. This allows the electromagnetic repulsion block 52 to generate corresponding electromagnetic attraction or repulsion according to the command, thereby ensuring the effectiveness of the thermal resistor 3, the temperature difference dynamic sensing component 4, and the electromagnetic flow valve 21 in small-range temperature control. This fully ensures the temperature balance between the two corresponding smelting areas, guarantees smelting quality, reduces the defect rate, and at the same time reduces the energy consumption of the temperature control device 1 and lowers smelting costs.

[0080] The third implementation method:

[0081] Figure 1 - Figure 9 The diagram illustrates an intelligent temperature control system for metallurgy. The stepped sensing cylinder 41 consists of a dynamic cylinder and an electric cylinder fixedly connected to the left and right ends of the dynamic cylinder. The dynamic cylinder and the electric cylinder are connected and engaged. The dynamic sensing block 43 is disposed inside the dynamic cylinder, and the electric beam connector 45 is embedded in the electric cylinder. The outer diameter of the dynamic cylinder is larger than the outer diameter of the electric cylinder. Insulating blocks 62 are fixedly connected to the left and right inner walls of the dynamic cylinder. Feedback connecting plates 6 are fixedly connected to the ends of the dynamic sensing block 43 and the insulating blocks 62 that are close to each other. Multiple cooperating feedback contact rods 61 are fixedly connected to the ends of the two feedback connecting plates 6 located on the same side that are close to each other.

[0082] Figure 1 and Figure 2 The input terminal of the intelligent temperature control processing unit is also connected to a failure monitoring feedback unit. The input terminal of the failure monitoring feedback unit is connected to the feedback contact rod 61. The cooperation between the failure monitoring feedback unit and the feedback contact rod 61 can effectively monitor the effectiveness of the thermal resistor 3. While ensuring precise and balanced temperature control of the temperature control device body 1, it can also monitor and sense the actual state of the thermal resistor 3. This avoids temperature control errors caused by damage or failure of the thermal resistor 3, ensuring the reliability and effectiveness of the monitoring data of the thermal resistor 3, thereby ensuring the effectiveness of the temperature control function of the temperature control device body 1 and ensuring the stability of metallurgical product quality.

[0083] Figure 1 - Figure 9 During the application of the temperature control device body 1, the magnetically insulating elastic sleeve 51 deforms accordingly with the magnitude of the electromagnetic force of the electromagnetic repulsion block 52, and acts on the dynamic sensing block 43, causing it to move within the stepped sensing cylinder 41. During the movement of the dynamic sensing block 43, it continuously approaches the insulating liner 62 on one side, and when it comes into contact with the feedback contact rods 61 at two corresponding positions on one side, the failure monitoring feedback unit acquires the contact data and determines that the thermal resistors 3 connected to the left and right sides of the stepped sensing cylinder 41 via the composite circuit 7 have failed. The failure trigger data is then transmitted to the intelligent temperature control processing unit. Based on the failure trigger data and the subsequent data transmitted by the area temperature difference monitoring unit, the intelligent temperature control processing unit determines the location of the failed thermal resistor 3 and transmits the relevant data of the failed thermal resistor 3 to the data output port through the abnormal warning unit. The abnormal warning unit also activates the alarm to issue an abnormal alarm, reminding the operator to respond according to the abnormal data and replace the failed thermal resistor 3.

[0084] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
