[0011] In some embodiments, Figure 1 A functional block diagram of the control system 100 for a continuous annealing furnace provided in this application embodiment is shown below. Figure 1 As shown, an embodiment of this application provides a control system 100 for a continuous annealing furnace, including: The process control module 101 is used to: detect the operating status of the continuous annealing furnace after it is started and run, and generate control commands for the continuous annealing furnace according to the operating status. The equipment management module 102 is used to: perform fault detection on the continuous annealing furnace during the operation of the continuous annealing furnace according to the control instructions, so as to obtain the fault detection result of the continuous annealing furnace, and determine the fault handling plan of the continuous annealing furnace if the fault detection result is that a fault exists.

[0012] In this embodiment, a control system 100 for a continuous annealing furnace is proposed. The continuous annealing furnace is an industrial device used for continuous heat treatment of metal strips, widely applied in the production of materials such as steel, aluminum alloys, and copper alloys. Through continuous heating, holding, and cooling processes, it eliminates work hardening, improves material forming properties, and enhances surface quality. The control system 100 is a system for managing and controlling the continuous annealing furnace. The control system 100 can control the production process of the continuous annealing furnace and manage its equipment maintenance.

[0013] The control system 100 includes a process control module 101 and an equipment control module 102, which are respectively connected to the continuous annealing furnace.

[0014] For example, the process control module 101 can control the production process of the continuous annealing furnace.

[0015] For example, the equipment management module 102 can manage the equipment maintenance of the continuous annealing furnace.

[0016] After the continuous annealing furnace is started up, the process control module 101 is used to detect the operating status of the continuous annealing furnace, wherein the operating status represents the real-time production status of the continuous annealing furnace.

[0017] For example, the running status can be normal or abnormal.

[0018] For example, the process control module 101 can collect the real-time operating parameters of the continuous annealing furnace and compare the real-time operating parameters with the standard parameters to determine the operating status of the continuous annealing furnace.

[0019] For example, when the real-time operating parameters differ from the standard parameters, the operating status is determined to be abnormal.

[0020] For example, when the real-time operating parameters and standard parameters are the same, the operating status is determined to be normal.

[0021] The process control module 101 is also used to generate control instructions for the continuous annealing furnace based on the operating status. The control instructions are real-time instructions for controlling the operation of the continuous annealing furnace.

[0022] For example, control instructions may include instructions to adjust the temperature of a continuous annealing furnace.

[0023] For example, control commands may include commands to adjust the state of the blowers inside the continuous annealing furnace.

[0024] For example, control commands may include commands to adjust the drive motor inside the continuous annealing furnace.

[0025] For example, control commands may include commands to adjust the furnace rollers inside the continuous annealing furnace.

[0026] The equipment management module 102 is used to perform fault detection on the continuous annealing furnace during the operation of the continuous annealing furnace according to the control instructions, so as to obtain the fault detection result of the continuous annealing furnace, wherein the fault detection result indicates whether there is a fault in the continuous annealing furnace.

[0027] For example, the fault detection result can be either that a fault exists or that a fault does not exist.

[0028] For example, the fault detection result may indicate that there is a fault in the drive motor of the continuous annealing furnace.

[0029] For example, fault detection results may indicate that there is a fault in the furnace rollers of a continuous annealing furnace.

[0030] The equipment management module 102 is also used to determine the fault handling plan for the continuous annealing furnace when the fault detection result indicates that a fault exists. The fault handling plan is a solution to the specific fault of the continuous annealing furnace.

[0031] For example, if the fault detection result indicates that there is no fault, the equipment management module 102 can also continuously monitor the continuous annealing furnace.

[0032] For example, the troubleshooting solution may specifically be to replace the parts in the continuous annealing furnace.

[0033] For example, the troubleshooting solution may specifically involve maintaining the faulty part.

[0034] The continuous annealing furnace management system 100 in this embodiment monitors the furnace's operating status in real time through the process control module 101. Based on the operating status, it generates control commands for the furnace, ensuring the timeliness of the operating status data and thus the accuracy of the control commands. This ensures the furnace operates according to the control commands, guaranteeing its operational stability. The equipment management module 102 performs fault detection on the furnace, obtaining the fault detection results and ensuring their timeliness. If a fault is detected, a fault handling plan is determined, ensuring the timeliness of the plan. Maintenance is then performed on the furnace based on the fault handling plan, preventing delays in furnace management and improving the timeliness of the management system 100's control over the continuous annealing furnace.

[0035] In some embodiments of this application, a control system 100 for a continuous annealing furnace is provided, wherein the process control module 101 includes: a heat balance diagnostic unit 1011; The thermal balance diagnostic unit 1011 is used for: Detect the heat parameters inside the continuous annealing furnace; The operating status of the continuous annealing furnace is determined based on the heat parameters.

[0036] In this embodiment, the process control module 101 includes a thermal balance diagnostic unit 1011.

[0037] The heat balance diagnostic unit 1011 is used to detect the heat parameters inside the continuous annealing furnace, wherein the heat parameters are used to represent the heat balance situation inside the continuous annealing furnace.

[0038] The heat balance diagnostic unit 1011 is also used to determine the operating status of the continuous annealing furnace based on heat parameters.

[0039] For example, the heat balance diagnostic unit 1011 constructs a mathematical model based on the principle of heat balance. The chemical energy brought in by the gas fuel is taken as the total input energy, and the output energy items include: physical heat carried away by the strip steel, physical heat carried away by the flue gas, physical heat carried away by the cooling water, physical heat absorbed by the superheated water, heat loss from the furnace wall, and other unstated heat losses.

[0040] For example, the thermal balance diagnostic unit 1011 collects the parameters corresponding to each output energy item in real time and calculates the thermal balance distribution under the current operating conditions.

[0041] For example, when producing strip steel of the same specification, if the proportion of a certain output energy item fluctuates abnormally compared to a preset standard threshold, it is determined that the subsystem corresponding to that energy item (such as the cooling system, the flue gas system, or the furnace body insulation system) has deteriorated or malfunctioned.

[0042] For example, the system has a built-in experience base that automatically pushes preset optimization solutions to the operation terminal based on the determined fault type.

[0043] In some embodiments of this application, a control system 100 for a continuous annealing furnace is provided, wherein the process control module 101 further includes a furnace roller system management unit 1012; The furnace roll system management unit 1012 is used to detect the furnace rolls of the continuous annealing furnace, determine the first usage state of the furnace rolls, and determine the first remaining life of the furnace rolls based on the first usage state.

[0044] In this embodiment, the process control module 101 further includes a furnace roll system management unit 1012.

[0045] The furnace roll system management unit 1012 is used to detect the furnace rolls of the continuous annealing furnace and determine the first usage state of the furnace rolls, wherein the first usage state indicates the usage status of the furnace rolls.

[0046] For example, the first usage state can represent the usage time of the furnace roller.

[0047] The furnace roll system management unit 1012 is also used to determine the first remaining life of the furnace roll based on the first usage state, wherein the first remaining life represents the service life of the furnace roll.

[0048] For example, the first remaining lifetime can be specifically 50 hours.

[0049] For example, the furnace roll system management unit 1012 includes a database that stores the technical parameters of all furnace rolls (such as model, installation location, and material) and preset accumulated experience (such as historical replacement records and common fault modes).

[0050] For example, the furnace roll system management unit 1012 accesses the inspection result data of the furnace roll (such as roll surface wear, nodule formation, bearing clearance, and motor current fluctuation).

[0051] For example, the furnace roll system management unit 1012 dynamically calculates the remaining lifespan of the furnace rolls based on a preset lifespan prediction model and the current inspection results, pushes a suggested furnace roll replacement cycle, and issues a reminder message 3 months in advance of the expected replacement date.

[0052] In some embodiments of this application, a control system 100 for a continuous annealing furnace is provided, wherein the process control module 101 further includes a radiant tube management unit 1013; Radiation tube management unit 1013 is used for: Inspect the radiant tubes of the continuous annealing furnace to determine the second usage status of the furnace rollers; The second remaining lifespan of the radiant tube is determined based on the second usage condition.

[0053] In this embodiment, the process control module 101 further includes a radiation tube management unit 1013.

[0054] The radiant tube management unit 1013 is used to detect the radiant tubes of the continuous annealing furnace and determine the second usage state of the furnace rollers, wherein the second usage state indicates the usage status of the radiant tubes.

[0055] For example, the second usage state can represent the usage time of the radiant tube.

[0056] The radiant tube management unit 1013 is also used to determine the second remaining lifetime of the radiant tube based on the second usage state.

[0057] For example, the second remaining lifetime can be specifically 45 hours.

[0058] For example, the radiator management unit 1013 can obtain the technical parameters and preset accumulated experience of all radiators.

[0059] For example, the radiant tube management unit 1013 accesses the inspection result data of the radiant tube (such as the deformation of the tube body and the composition of online exhaust gas), pushes the recommended replacement cycle of the radiant tube, and issues a reminder message 3 months in advance of the expected replacement date.

[0060] In some embodiments of this application, a control system 100 for a continuous annealing furnace is provided, wherein the process control module 101 is further configured to: The control command is determined based on the first remaining lifetime and the second remaining lifetime.

[0061] In this embodiment, the process control module 101 is further configured to determine control commands based on the first remaining lifetime and the second remaining lifetime.

[0062] For example, the process control module 101 can adjust the real-time parameters of the continuous annealing furnace according to the first remaining life and the second remaining life, and then generate control commands.

[0063] In some embodiments of this application, a control system 100 for a continuous annealing furnace is provided, wherein the equipment control module 102 includes: an instrument assessment unit 1021; Instrument assessment unit 1021 is used for: Obtain the instrument parameters of the equipment management module 102; Based on the instrument parameters, the first test result of the continuous annealing furnace is determined.

[0064] In this embodiment, the equipment management module 102 includes an instrument assessment unit 1021.

[0065] The instrument assessment unit 1021 is used to acquire the instrument parameters of the continuous annealing furnace, wherein the instrument parameters are the real-time parameters of the instruments on the continuous annealing furnace.

[0066] The instrument assessment unit 1021 is also used to determine the first test result of the continuous annealing furnace based on the instrument parameters, wherein the first test result is the test result of the continuous annealing furnace instrument.

[0067] For example, the instrument assessment unit 1021 designs assessment indicators for key process detection equipment during the operation of the continuous annealing furnace, specifically including: nitrogen and hydrogen injection flow rate and pressure, furnace pressure detection, water content detection, micro-oxygen detection, hydrogen content detection, furnace temperature detection, belt temperature detection, air temperature and air pressure, and cooling water temperature and water pressure.

[0068] For example, the instrument assessment unit 1021 collects repetitive fault data from each testing device. When the frequency of the same type of fault (such as furnace pressure fluctuation or abnormal hydrogen content) exceeds a preset threshold, it automatically associates historical processing records and pushes targeted problem-solving solutions.

[0069] In some embodiments of this application, a control system 100 for a continuous annealing furnace is provided, and the equipment control module 102 further includes: a fan status monitoring unit 1022; The fan status monitoring unit 1022 is used for: Detect the first operating parameters of the internal fan of the continuous annealing furnace; Based on the first operating parameters, the second detection result of the continuous annealing furnace is determined.

[0070] In this embodiment, the equipment management module 102 further includes a fan status monitoring unit 1022.

[0071] The fan status monitoring unit 1022 is used to detect the first operating parameter of the fan inside the continuous annealing furnace, wherein the first operating parameter is the real-time parameter of the fan inside the continuous annealing furnace.

[0072] The fan status monitoring unit 1022 is also used to determine the second detection result of the continuous annealing furnace based on the first operating parameters, wherein the second detection result is the detection result of the fan inside the continuous annealing furnace.

[0073] For example, the fan status monitoring unit 1022 has a built-in vibration spectrum analysis and temperature trend analysis model for monitoring the vibration and temperature of the fan bearing housing of the annealing furnace. When the vibration amplitude or temperature exceeds the alarm threshold of different levels, it pushes the corresponding handling solution (such as dynamic balance correction, adding grease, or bearing replacement) in combination with the fault feature library (such as imbalance, misalignment, bearing fault characteristic frequency).

[0074] In some embodiments of this application, a control system 100 for a continuous annealing furnace is provided, and the equipment control module 102 further includes: a furnace roller frequency conversion drive monitoring unit 1023; The furnace roller frequency conversion drive monitoring unit 1023 is used for: Detect the second operating parameter of the furnace roller motor inside the continuous annealing furnace; Based on the second operating parameters, the third test result of the continuous annealing furnace is determined.

[0075] In this embodiment, the equipment management module 102 further includes a furnace roller frequency conversion drive monitoring unit 1023.

[0076] The furnace roller frequency conversion drive monitoring unit 1023 is used to detect the second operating parameters of the furnace roller motor inside the continuous annealing furnace, wherein the second operating parameters are the real-time parameters of the furnace roller motor inside the continuous annealing furnace.

[0077] The furnace roller frequency conversion drive monitoring unit 1023 is also used to determine the third detection result of the continuous annealing furnace based on the second operating parameters, wherein the third detection result is the detection result of the furnace roller motor inside the continuous annealing furnace.

[0078] For example, the furnace roller frequency conversion drive monitoring unit 1023 performs statistical monitoring on the frequency converter temperature, output current, output torque and motor body temperature of the furnace roller motor.

[0079] For example, the furnace roller frequency conversion drive monitoring unit 1023 establishes the normal operating baseline of each parameter. When the parameter is detected to be outside the baseline range or abnormal fluctuations occur (such as sudden current change or torque overload), the corresponding handling solution is automatically pushed (such as checking mechanical jamming, optimizing frequency converter parameters, and cleaning motor heat dissipation).

[0080] In some embodiments of this application, a control system 100 for a continuous annealing furnace is provided, wherein the equipment control module 102 is further configured to: The fault detection result is determined based on the first, second, and third test results.

[0081] In this embodiment, the device management module 102 is also used to determine the fault detection result based on the first detection result, the second detection result, and the third detection result.

[0082] For example, if the first detection result, the second detection result, and the third detection result are all without fault, the fault detection result is determined to be without fault.

[0083] For example, if the first detection result, the second detection result, or the third detection result indicates that a fault exists, the fault detection result is determined to be faulty.

[0084] For example, communication is established with the annealing furnace process control system, line operation control system, and equipment vibration detection system to collect the required data parameters into the intelligent control system 100 database; a database is constructed using the location information related to the technical parameters of the furnace rollers and radiant tubes. Real-time system information and system structure are then established.

[0085] For example, the collected data is combined with the system architecture to decompose the annealing furnace system into multiple small data association systems. Composite rules are established in both time and cycle dimensions. At the same time, diagnostic rules or models are established by combining process interlocking characteristics, such as establishing the cooling efficiency of the annealing furnace heat exchanger, combustion status evaluation, and equipment health, so as to achieve a more accurate health assessment in the daily operation of the annealing furnace.

[0086] For example, the model judgment logic is used to push response solutions to the interface of equipment and process management and execution personnel, and includes the name of the alarm device for abnormal production operation status monitoring data, alarm time, alarm level and whether someone has confirmed the status.

[0087] This embodiment has the following beneficial effects: 1. Intelligent process diagnosis: By performing "energy audit" on the annealing furnace based on the principle of heat balance, it can accurately locate hidden faults in various subsystems of the furnace (cooling, flue gas, and heat preservation) without intruding on production, changing "post-event remediation" to "pre-event warning" and improving the stability of process control.

[0088] 2. Precision equipment maintenance: For long-cycle components such as furnace rollers and radiant tubes, a dynamic life prediction mechanism based on inspection results and an early warning mechanism three months in advance have been introduced to avoid unplanned downtime and realize the transformation from "periodic maintenance" to "predictive maintenance".

[0089] 3. Closed-loop management and control system: Deeply integrate process parameters with equipment status, establish indicator assessment for key instruments, conduct feature-level monitoring of rotating equipment such as fans and motors, and automatically push handling solutions through statistical repetitive faults, thus constructing a closed-loop intelligent management and control system of "monitoring-diagnosis-push-handling", which significantly reduces fault handling time.
