Description

Technical Field

[0001] This application relates to the field of casting control technology, and in particular to a casting alarm interlock control method. Background Technology

[0002] With the expanding applications of aluminum materials, various aluminum manufacturing equipment has developed rapidly. Casting is a commonly used aluminum processing method, and the horizontal hot-top aluminum rod deep-well casting machine is currently the most widely used semi-continuous aluminum and aluminum alloy casting machinery. In the aluminum rod casting process, it is necessary to rationally proportion the raw materials and add them to a melting furnace for melting. Impurities and gases in the molten material are removed through degassing and slag removal refining processes to form molten aluminum. Then, under specific casting process conditions, the molten aluminum is cast using a casting machine to form cylindrical aluminum rods of various specifications.

[0003] During the aluminum rod casting process, manual intervention is usually required. Due to operator error or unforeseen circumstances, a large amount of molten aluminum may leak into the deep well during casting, causing accidents such as explosions. Alternatively, there may be sudden water or power outages during casting, resulting in low safety. Summary of the Invention

[0004] To improve the safety of aluminum bars during the casting process, this application provides a casting alarm method.

[0005] This application provides a casting alarm interlock control method, which includes the following steps:

[0006] Obtain the detection node;

[0007] Based on the detection nodes, obtain node detection information;

[0008] Determine whether the node detection information meets the preset security standards;

[0009] If the preset security standard is not met, then an anomaly detection item is obtained based on the node detection information;

[0010] Based on the anomaly detection items, obtain the corresponding anomaly detection data;

[0011] Determine whether the abnormal detection data meets the preset alarm criteria;

[0012] If the preset alarm criteria are not met, a corresponding abnormal prompt signal will be generated based on the abnormal detection data.

[0013] If the preset alarm criteria are met, the abnormal detection data will be analyzed according to the preset alarm criteria to generate a linkage alarm signal;

[0014] Based on the alarm signal, perform the safety operation corresponding to the alarm signal.

[0015] By adopting the above technical solution, the node detection information of each detection node is obtained, and abnormal detection items that do not meet the preset safety standards in the node detection information are identified. Abnormal detection data in the abnormal detection items are further obtained, and the abnormal detection data is analyzed in combination with the preset alarm standards to obtain the linkage alarm signal that meets the preset alarm standards. The system executes the corresponding safety operation according to the linkage alarm signal. The obtained linkage alarm signal can more comprehensively reflect the alarm information of the detection nodes during the aluminum rod casting process, thereby improving the safety of the aluminum rod during the casting process.

[0016] Optionally, the abnormal detection data includes aluminum liquid level data, and the step of analyzing the abnormal detection data according to a preset alarm standard and generating a linkage alarm signal includes the following steps:

[0017] Based on the aluminum liquid level data, obtain the unit fluctuation rate value;

[0018] According to the preset alarm standard, obtain the fluctuation alarm threshold;

[0019] Determine whether the unit fluctuation rate value exceeds the fluctuation alarm threshold;

[0020] If the unit fluctuation rate value meets the fluctuation alarm threshold, then the difference between the unit fluctuation rate value and the fluctuation alarm threshold is obtained, and a liquid level alarm signal is obtained based on the difference value.

[0021] Based on the difference value and the preset alarm gradient, the alarm signal strength corresponding to the liquid level alarm signal is set;

[0022] If the alarm signal strength meets the preset linkage alarm standard, then the linkage alarm signal is acquired.

[0023] By adopting the above technical solution, the actual fluctuation of the aluminum liquid level can be reflected according to the intensity of the alarm signal corresponding to the liquid level alarm signal, thereby improving the safety of aluminum liquid level detection during the casting process of aluminum rods.

[0024] Optionally, if the alarm signal strength meets the preset linkage alarm standard, obtaining the linkage alarm signal includes the following steps:

[0025] Based on the liquid level alarm signal, obtain the tilting furnace self-test signal;

[0026] The tilting furnace return status is obtained based on the tilting furnace self-test signal;

[0027] Based on the tilting furnace return status and the preset return standard, the return difference and the liquid level alarm signal are obtained as the linkage alarm signal.

[0028] By adopting the above technical solution, the return status of the tilting furnace can be analyzed while acquiring the liquid level alarm signal, which makes it easier for the subsequent system to adjust the return of the tilting furnace more accurately based on the return difference.

[0029] Optionally, if the alarm signal strength meets the preset linkage alarm standard, obtaining the linkage alarm signal includes the following steps:

[0030] The flow rate of the aluminum liquid in the flow channel is obtained based on the liquid level alarm signal;

[0031] The gate valve opening is obtained based on the flow rate of the molten aluminum in the flow channel;

[0032] According to the preset alarm standard, obtain the opening alarm threshold;

[0033] Determine whether the opening degree of the gate valve exceeds the opening degree alarm threshold;

[0034] If the gate valve opening degree exceeds the opening degree alarm threshold, then the gate valve opening degree and the liquid level alarm signal are used as the linkage alarm signal.

[0035] By adopting the above technical solution, the flow rate of aluminum liquid in the flow channel is analyzed while the liquid level alarm signal is obtained, and the corresponding gate valve opening is further obtained. If the gate valve opening exceeds the opening alarm threshold, the gate valve opening that does not meet the opening alarm threshold is obtained as the corresponding linkage alarm signal based on the liquid level alarm signal. Thus, an adaptive alarm can be made according to the actual flow rate of aluminum liquid in the flow channel and the corresponding gate valve opening, which facilitates the subsequent system to accurately adjust the gate valve opening.

[0036] Optionally, after using the gate valve opening degree and the liquid level alarm signal as the linkage alarm signal, the following steps are further included:

[0037] The volume of aluminum liquid in the accident pool is obtained based on the flow rate of the aluminum liquid in the flow channel;

[0038] The volume difference is obtained based on the flow rate of the molten aluminum in the flow channel and the volume of the molten aluminum in the emergency pool;

[0039] Determine whether the volume difference meets the preset difference standard;

[0040] If the volume difference does not meet the preset difference standard, then an accident pool warning message is obtained based on the volume difference.

[0041] By adopting the above technical solution, the real-time information of the flow rate of the aluminum liquid in the flow channel can be reflected based on the volume difference, thereby improving the safety of the aluminum rod during the casting process.

[0042] Optionally, if the alarm signal strength meets the preset linkage alarm standard, obtaining the linkage alarm signal includes the following steps:

[0043] Based on the liquid level alarm signal, obtain the automatic device signal;

[0044] Based on the signal from the automatic device, the outlet alarm signal is obtained as the linkage alarm signal.

[0045] By adopting the above technical solution, while issuing a liquid level alarm signal, the system can promptly block the outlet based on the outlet alarm signal, reducing the occurrence of emergencies.

[0046] Optionally, the abnormal detection data includes cast well water temperature data, and the step of analyzing the abnormal detection data according to a preset alarm standard to obtain a linkage alarm signal includes the following steps:

[0047] Based on the cast well water temperature data, obtain the cast well water temperature value;

[0048] According to the preset alarm standard, obtain the water temperature alarm threshold;

[0049] Determine whether the cast well water temperature exceeds the water temperature alarm threshold;

[0050] If the well water temperature exceeds the water temperature alarm threshold, the linkage alarm signal is obtained.

[0051] By adopting the above technical solution, if the water temperature in the casting well is detected to exceed the corresponding water temperature alarm threshold, the alarm signal can be used to comprehensively alarm the important safety nodes of the casting device, thereby improving the safety of aluminum rods during the casting process.

[0052] Optionally, the abnormal detection data includes circulating water data, and the step of analyzing the abnormal detection data according to a preset alarm standard to obtain a linkage alarm signal includes the following steps:

[0053] Based on the preset alarm criteria, obtain the circulating water indicators;

[0054] Determine whether the circulating water data meets the circulating water index;

[0055] If the circulating water data does not meet the circulating water index, then the linkage alarm signal is obtained.

[0056] By adopting the above technical solution, if the circulating water data is found to be inconsistent with the corresponding circulating water index, the alarm signal can be used to comprehensively alarm the important safety nodes of the casting device, thereby improving the safety of aluminum rods during the casting process.

[0057] Optionally, after obtaining the corresponding anomaly detection data based on the anomaly detection item, the method further includes the following steps:

[0058] Determine whether the abnormal detection data meets the preset early warning standard;

[0059] If the abnormal detection data meets the preset early warning standard, an early warning signal is obtained.

[0060] By adopting the above technical solution, early warning processing can be performed on abnormal detection items corresponding to abnormal detection data, thereby reducing the occurrence of security problems.

[0061] Optionally, obtaining the corresponding anomaly detection data based on the anomaly detection item further includes the following steps:

[0062] Determine whether the abnormal detection data meets the preset alarm criteria;

[0063] If the abnormal detection data meets the preset alarm standard, an emergency power signal is acquired, and the preset emergency power supply is switched on according to the emergency power signal.

[0064] By adopting the above technical solution, a preset emergency power supply can continuously supply power to the system device in the event of an abnormal power outage.

[0065] In summary, this application includes the following beneficial technical effects: acquiring node detection information of each detection node, identifying abnormal detection items in the node detection information that do not meet the preset safety standards, further acquiring abnormal detection data in the abnormal detection items, analyzing each abnormal detection data in combination with the preset alarm standards, acquiring linkage alarm signals that meet the preset alarm standards, and the system executing corresponding safety operations based on the linkage alarm signals. The acquired linkage alarm signals can more comprehensively reflect the alarm information of the detection nodes during the aluminum rod casting process, thereby improving the safety of the aluminum rod during the casting process.

[0077] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0078] like Figure 1 The diagram shown is a layout of an aluminum rod casting equipment. The corresponding relationships between the components and markings are as follows: ① Insulation furnace; ② Automatic mechanical device; ③ Degassing box; ④ Filter box; ⑤ Aluminum liquid drain valve; ⑥ Aluminum liquid drain valve; ⑦ Flow channel gate; ⑧ Liquid level measuring instrument; ⑨ Casting machine; ⑩ Casting well water temperature detection and alarm instrument.

[0079] Under normal circumstances, the deep well casting process of aluminum processing enterprises is as follows: First, the aluminum liquid enters the holding furnace through the melting furnace, then flows into the degassing box through the automated mechanical device, then flows through the filter box, until it reaches the flow channel gate, and finally flows to the mold plate through the liquid level measuring instrument. The finished aluminum rod is obtained by the crystallizer. When the relevant safety parameters are abnormal during the casting process, the supply of aluminum liquid to the flow channel is cut off, and the aluminum liquid in the flow channel is discharged into the emergency accident pool through the aluminum liquid drain valve.

[0080] This application discloses a casting alarm interlock control method, such as... Figure 2 As shown, it includes the following steps:

[0081] S101, Obtain the detection node;

[0082] S102. Obtain node detection information based on the detection nodes;

[0083] S103. Determine whether the node detection information meets the preset security standards;

[0084] S104. If the preset safety standards are not met, obtain the abnormal detection items based on the node detection information.

[0085] S105. Obtain the corresponding anomaly detection data based on the anomaly detection items;

[0086] S106. Determine whether the abnormal detection data meets the preset alarm standard;

[0087] S107. If the preset alarm standard is not met, a corresponding abnormal prompt signal will be generated based on the abnormal detection data.

[0088] S108. If the preset alarm criteria are met, analyze the abnormal detection data according to the preset alarm criteria and generate a linkage alarm signal.

[0089] S109. Based on the linkage alarm signal, perform the safety operation corresponding to the linkage alarm signal.

[0090] Inspection nodes refer to the various safety inspection points in the deep well casting process of aluminum rods. These safety inspection nodes involve the key core links that the aluminum liquid passes through in the casting device. These key core links are also important nodes in the deep well casting process of aluminum processing enterprises. Node inspection information refers to the safety inspection information corresponding to each inspection node.

[0091] The preset security standard refers to the security standard that the node detection information should meet. The abnormal detection item refers to the node detection information that does not meet the preset security standard. Through the node detection information, the abnormal detection data corresponding to the detection node can be further obtained.

[0092] The criteria for identifying major production safety hazards in aluminum processing using deep-well casting technology are roughly as follows: ① Fixed molten aluminum outlets lack mechanical or automatic locking devices; the interfaces between the molten aluminum outlet and the flow channel, and between the flow channel and the casting mold plate, in both fixed and tilting molten aluminum furnaces, lack liquid level monitoring and interlocking alarm devices; ② The installed liquid level sensors are not interlocked with the quick-cut-off valve and emergency discharge valve on the molten aluminum flow channel; tilting molten aluminum furnaces cannot automatically reset in an emergency; ③ The ground where raw materials are placed in the furnace is damp; and there are dampness in the molten aluminum furnace, holding furnace, and casting work areas. ④ The circulating water system of the deep well casting purifier is not equipped with monitoring and alarm devices for inlet and outlet water temperature, inlet water pressure, and inlet water flow. The monitoring and alarm devices are not interlocked with the quick shut-off valve and emergency discharge valve on the flow channel, nor with the control system of the tilting smelting furnace. The circulating water system is not equipped with an emergency water source. The emergency water source pipeline is not connected in parallel with two control valves, or is missing a normally closed solenoid valve (automatic control valve). ⑤ The aluminum casting process is not equipped with emergency discharge or emergency storage facilities in a standardized manner. ⑥ The wire rope of the ingot tray bracket of the wire hoisting system is not regularly inspected and replaced.

[0093] After eliminating the aforementioned major production safety hazards, the node detection information of each of the above detection devices is further collected. Based on the preset safety standards, the abnormal detection items in the node detection information during the aluminum rod casting process are analyzed and judged. The corresponding abnormal detection data is then obtained through the abnormal detection items.

[0094] The preset alarm standard refers to the various criteria for abnormal detection data to reach the alarm. The linkage alarm signal refers to the analysis of the associated detection data when an alarm is issued for an abnormal detection data that meets the preset alarm standard, and the linkage alarm is issued by combining the abnormal detection data and the associated detection data.

[0095] For example, if a large fluctuation in the molten aluminum level is detected in a short period of time, potentially indicating a risk of aluminum leakage from the mold, an alarm is triggered on the molten aluminum level. Simultaneously, the tilt angle of the tilting furnace supplying the molten aluminum is analyzed. Based on preset alarm standards, the tilting furnace should reset when a risk of aluminum leakage from the mold occurs. Furthermore, the alarm threshold for the tilt angle of the tilting furnace can be determined based on the preset alarm standards. If the tilt angle exceeds the alarm threshold, a linkage alarm signal regarding the tilt angle of the tilting furnace is issued simultaneously with the molten aluminum level alarm. The system then performs corresponding safety operations based on the linkage alarm signal.

[0096] In the casting alarm method provided in this embodiment, node detection information of each detection node is obtained, abnormal detection items in the node detection information that do not meet the preset safety standards are identified, abnormal detection data in the abnormal detection items are further obtained, and each abnormal detection data is analyzed in combination with the preset alarm standards to obtain a linkage alarm signal that meets the preset alarm standards. The system performs corresponding safety operations according to the linkage alarm signal. The obtained linkage alarm signal can more comprehensively reflect the alarm information of the detection nodes during the casting process of aluminum rod, thereby improving the safety of aluminum rod during the casting process.

[0097] In one embodiment of this example, such as Figure 3 As shown, the abnormal detection data includes aluminum liquid level data, and step S108 includes the following steps:

[0098] S201. Obtain the unit fluctuation rate value based on the aluminum liquid level data;

[0099] S202. Obtain the fluctuation alarm threshold according to the preset alarm standard;

[0100] S203. Determine whether the unit fluctuation rate value exceeds the fluctuation alarm threshold.

[0101] S204. If the unit fluctuation rate value meets the fluctuation alarm threshold, then obtain the difference between the unit fluctuation rate value and the fluctuation alarm threshold, and obtain the liquid level alarm signal based on the difference value.

[0102] S205. Set the alarm signal strength corresponding to the liquid level alarm signal based on the difference value and the preset alarm gradient.

[0103] S206. If the alarm signal strength meets the preset linkage alarm standard, then obtain the linkage alarm signal.

[0104] In practical applications, the unit fluctuation rate value refers to the rate at which the aluminum liquid level drops per unit time; the fluctuation alarm threshold refers to the value at which the rate at which the aluminum liquid level drops per unit time reaches the alarm threshold; the preset alarm gradient refers to the alarm level gradient corresponding to the magnitude of the difference value, with smaller differences corresponding to lower alarm level gradients and larger differences corresponding to higher alarm level gradients. A lower alarm level gradient corresponds to a weaker alarm signal strength, while a higher alarm level gradient corresponds to a stronger alarm signal strength. If the alarm signal strength at this time meets the preset linkage alarm standard, the associated abnormal detection data is further analyzed to obtain the corresponding linkage alarm signal. The linkage alarm signal refers to the alarm signal of the associated safety processing device issued at the same time as the alarm signal is issued based on the abnormal detection data.

[0105] For example, when the aluminum molten level drops rapidly, the level detector senses the change in the aluminum molten level. The unit rate of descent of the aluminum molten level is 5 cm per minute, and the fluctuation alarm threshold is 2.5 cm per minute. It can be determined that the unit rate of descent of the aluminum molten level has exceeded the fluctuation alarm threshold, thus obtaining a level alarm signal with a difference of 2.5 cm per minute. According to the preset alarm gradients, the first alarm gradient corresponds to a difference of 0.5 cm per minute, the second alarm gradient corresponds to a difference of 1.5 cm per minute, and the third alarm gradient corresponds to a difference of 2.5 cm per minute. Therefore, matching the third alarm gradient with a difference of 2.5 cm per minute results in the strongest output alarm signal. The alarm signal strength reflects the actual fluctuation of the aluminum molten level, improving the safety of aluminum molten level detection during the casting process.

[0106] In one embodiment of this example, such as Figure 4 As shown, step S206 includes the following steps:

[0107] S301. Obtain the tilting furnace self-test signal based on the liquid level alarm signal;

[0108] S302. Obtain the tilting furnace return status based on the tilting furnace self-test signal;

[0109] S303. Based on the tilting furnace return status and preset return standard, obtain the return difference and liquid level alarm signals as linkage alarm signals.

[0110] In practical applications, the tilting furnace self-check signal refers to the signal that requires the tilting furnace to return to its original position when a liquid level alarm signal is issued, and the signal is used to check the return status of the tilting furnace; the preset return standard refers to the standard that the tilting furnace should meet when a liquid level alarm signal is issued; the return difference refers to the difference between the return status of the tilting furnace when a liquid level alarm signal is issued and the preset return standard.

[0111] For example, the tilting furnace is hydraulically driven and can tilt back in case of casting failure, or safely reset after depressurization in the event of a power outage. When a liquid level alarm signal is issued, the tilting furnace is checked based on its self-test signal to obtain the corresponding tilting furnace return status. Furthermore, based on the difference between the tilting furnace return status and the corresponding preset return standard, combined with the liquid level alarm signal, a corresponding linkage alarm signal is issued.

[0112] While acquiring the liquid level alarm signal, the return status of the tilting furnace is analyzed, which makes it easier for the subsequent system to adjust the return of the tilting furnace more accurately based on the return difference.

[0113] In one embodiment of this example, such as Figure 5 As shown, step S206 includes the following steps:

[0114] S401. Obtain the flow rate of aluminum liquid in the flow channel based on the liquid level alarm signal;

[0115] S402. Obtain the gate valve opening degree based on the flow rate of the aluminum liquid in the flow channel;

[0116] S403. Obtain the opening alarm threshold according to the preset alarm standard;

[0117] S404. Determine whether the gate valve opening degree exceeds the opening degree alarm threshold.

[0118] S405. If the gate valve opening degree meets the opening degree alarm threshold, then the gate valve opening degree and liquid level alarm signals will be used as linkage alarm signals.

[0119] In practical applications, the opening alarm threshold refers to the alarm threshold set according to the opening degree of the pneumatic gate valve when a liquid level alarm signal is issued, which requires driving the pneumatic gate valve to descend and cut off the supply of molten aluminum. If the opening degree of the pneumatic gate valve exceeds the opening alarm threshold at this time, the opening degree of the gate valve will be used as the corresponding linkage alarm signal.

[0120] For example, while issuing a liquid level alarm signal, the flow rate of molten aluminum in the flow channel is obtained through a liquid level detection instrument. Based on the flow rate, the actual gate valve opening of the pneumatic gate is further deduced. At this time, the gate valve opening is 30%. Since the obtained liquid level alarm signal is the strongest, the corresponding opening alarm threshold is 0%, which means the pneumatic gate needs to be in a completely closed state. The 30% gate valve opening is further used as a linkage alarm signal. While obtaining the liquid level alarm signal, the flow rate of molten aluminum in the flow channel is analyzed to obtain the corresponding gate valve opening. If the gate valve opening exceeds the opening alarm threshold, the gate valve opening that does not meet the opening alarm threshold is obtained as the corresponding linkage alarm signal based on the liquid level alarm signal. Thus, an adaptive alarm can be made according to the actual flow rate of molten aluminum in the flow channel and the corresponding gate valve opening, which facilitates the subsequent accurate adjustment of the gate valve opening by the system.

[0121] In one embodiment of this example, such as Figure 6 As shown, the following steps are included after step S405:

[0122] S501. Obtain the volume of aluminum liquid in the emergency pool based on the flow rate of the aluminum liquid in the flow channel;

[0123] S502. Obtain the volume difference based on the flow rate of the aluminum liquid in the flow channel and the volume of the aluminum liquid in the emergency pool;

[0124] S503. Determine whether the volume difference meets the preset difference standard;

[0125] S504. If the volume difference does not meet the preset difference standard, obtain the accident pool warning information based on the volume difference.

[0126] In practical applications, the volume of aluminum liquid in the accident pool refers to the volume of aluminum liquid collected in the accident pool. The preset difference standard refers to the volume difference standard between the reduced aluminum liquid in the flow channel and the excess aluminum liquid in the accident pool when a failure occurs during the casting process and the aluminum liquid in the flow channel needs to be discharged into the accident pool.

[0127] For example, during normal casting, the molten aluminum level is stable. When the level drops rapidly, the level detector senses the change and triggers a corresponding alarm signal. This is then controlled by the PLC, opening the molten aluminum drain valve and draining the remaining molten aluminum from the flow channel into the emergency pool. The volume difference obtained at this time is 3 liters. According to the preset difference standard, the volume difference standard is 0 liters, which means that all the molten aluminum in the flow channel must be drained into the emergency pool. However, the actual volume difference obtained at this time is 3 liters, indicating that there are still 3 liters of molten aluminum in the flow channel that have not been completely drained into the emergency pool. The volume difference reflects the real-time information of the molten aluminum flow in the flow channel, improving the safety of the aluminum rod during the casting process.

[0128] In one embodiment of this example, such as Figure 7 As shown, step S206 includes the following steps:

[0129] S601. Obtain the automatic device signal based on the liquid level alarm signal;

[0130] S602. Based on the signal from the automatic device, obtain the outlet alarm signal and the liquid level alarm signal as linkage alarm signals.

[0131] In practical applications, when a fault such as aluminum leakage occurs in the mold during the casting process, the alarm system simultaneously sends a signal to the automatic mechanical device of the fixed holding furnace to drive the automatic mechanical device to block the outlet. At the same time, it acquires the outlet alarm signal as a linkage alarm signal. Based on the outlet alarm signal, the actual blocking status of the outlet can be obtained. Thus, while issuing the liquid level alarm signal, the system can promptly block the outlet based on the outlet alarm signal, reducing the occurrence of emergencies.

[0132] In one embodiment of this example, such as Figure 8 As shown, the abnormal detection data includes cast well water temperature data, and step S108 includes the following steps:

[0133] S701. Obtain the cast well water temperature value based on the cast well water temperature data;

[0134] S702. Obtain the water temperature alarm threshold according to the preset alarm standard;

[0135] S703. Determine whether the well water temperature exceeds the water temperature alarm threshold.

[0136] S704. If the water temperature in the cast well exceeds the water temperature alarm threshold, a linkage alarm signal will be obtained.

[0137] In practical applications, the casting well water temperature value refers to the actual water temperature value of the casting well during the casting process. The water temperature alarm threshold refers to the value at which the actual water temperature of the casting well reaches the alarm standard during the casting process. The water temperature alarm threshold is based on the requirements of the casting process. The water temperature in the casting well is maintained by circulation through a cooling tower. If the water temperature exceeds the water temperature alarm threshold, there is a risk that a large amount of high-temperature aluminum liquid will enter the well.

[0138] For example, thermocouples are used to monitor the water temperature in the casting well in real time. Based on the water temperature alarm threshold, when the water temperature exceeds 60℃, the alarm system is triggered, and the water temperature alarm signal is obtained. The signal is then controlled by a PLC, and further signals from the automatic device, the gate valve opening, and the volume difference of the molten aluminum are obtained as linkage alarm signals. Through the linkage alarm signals, all important safety nodes of the casting device can be alarmed, thus improving the safety of the aluminum rods during the casting process.

[0139] In addition, a natural gas alarm device is installed near the gas pipeline near the furnace. While receiving the linkage alarm signal, the natural gas alarm device detects the natural gas. If a natural gas leak is detected, the system issues an audible and visual alarm and simultaneously drives the natural gas shut-off valve to cut off the gas supply.

[0140] In one embodiment of this example, such as Figure 9 As shown, the abnormal detection data includes circulating water data, and step S108 includes the following steps:

[0141] S801. Obtain circulating water indicators according to preset alarm standards;

[0142] S802. Determine whether the circulating water data meets the circulating water indicators;

[0143] S803. If the circulating water data does not meet the circulating water index, a linkage alarm signal will be obtained.

[0144] In practical applications, circulating water data includes data such as cooling water, water pressure, and water flow rate. Circulating water indicators refer to the various safety indicators that circulating water needs to achieve during the casting process.

[0145] At the start of casting, the self-test displays the water flow rate and pressure. The cooling water flow rate, pressure, and temperature sensors are all set to range parameters. If the water pressure and flow rate detection system detects that the circulating water data does not meet the corresponding circulating water indicators, it triggers a circulating water alarm signal. Further signals from the automatic device, the gate valve opening, and the volume difference of the molten aluminum are then used as linked alarm signals. These linked alarm signals comprehensively monitor critical safety points in the casting process, enhancing the safety of the aluminum bars during casting.

[0146] In one embodiment of this example, such as Figure 10 As shown, the following steps are included after step S105:

[0147] S901. Determine whether the abnormal detection data meets the preset early warning standard;

[0148] S902. If the abnormal detection data meets the preset early warning standard, an early warning signal is obtained.

[0149] In practical applications, the preset early warning standard refers to the standard under which various abnormal detection data reach the system's early warning criteria. After acquiring abnormal detection data, the system first judges the abnormal detection data according to the preset early warning standard. If some abnormal detection data does not meet the preset early warning standard, the system obtains the early warning signal for the corresponding abnormal detection item, thereby enabling early warning processing for the abnormal detection item corresponding to the abnormal detection data and reducing the occurrence of safety issues.

[0150] In one embodiment of this example, such as Figure 11 As shown, the following steps are included after step S105:

[0151] S1001. Determine whether the abnormal detection data meets the preset alarm standard;

[0152] S1002. If the abnormal detection data meets the preset alarm standard, then obtain the emergency power signal and switch to the preset emergency power supply according to the emergency power signal.

[0153] In practical applications, to prevent the alarm detection device from malfunctioning after a linkage alarm signal is triggered, or in the event of a sudden power or water outage during the casting process, the system generates a corresponding emergency power signal based on the linkage alarm signal. This emergency power signal then switches the electrical equipment to the preset emergency power supply during the casting process. The preset emergency power supply can be set as an uninterruptible power supply (UPS). Once the UPS is switched on, it provides power to the liquid level detector, casting well water temperature detector, natural gas detector, aluminum liquid drain valve, pneumatic gate, mechanical locking device, emergency water supply valve, and emergency lighting in the casting equipment. Thus, in the event of an abnormal power outage, the preset emergency power supply can continuously power the system.

[0154] The casting hoisting system is implemented in accordance with metallurgical industry standards. The braking system adopts a dual braking system. A speed sensor can be added to the control speed circuit on the drum, which can improve the accuracy of speed control.

[0155] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
