Description
Technical Field
[0001] The invention relates to the technical field of titanium-aluminium solid-liquid composite casting, in particular to a titanium-aluminium solid-liquid composite casting safety device. Background Art
[0002] In the production process of titanium aluminum solid-liquid composite pipes, a crucial step is the use of crystallizers, in which the flow rate and temperature control of cooling water are crucial links. If these key parameters are not properly managed and adjusted, the material may not be crystallized in time during the continuous composite process, thus affecting the quality of the final product. In addition, during the heating process of the medium-frequency graphite furnace, cracking defects may occur due to uneven heating of the material. These cracks may cause the leakage of high-temperature aluminum liquid, which will flow into the collection well of secondary cooling water. When these high-temperature aluminum liquids come into contact with water vapor, violent chemical reactions will occur to produce hydrogen. If hydrogen accumulates rapidly in a local space and its concentration in the air reaches about 4%, if it encounters high-temperature aluminum liquid or other ignition sources at this time, it is very likely to cause an explosion accident, posing a serious threat to the production environment and the safety of operators. Summary of the invention

[0050] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0051] like Figures 1 to 5 As shown, a titanium-aluminum solid-liquid composite casting safety device is provided on a furnace base 1, a furnace 2 is provided on the furnace base 1, a deep well 6 is provided on one side of the base 1, and the safety device includes:
[0052] An aluminum ingot tank 3, movably disposed on one side of the melting furnace 2, for storing high-temperature aluminum liquid leaking from the melting furnace 2;
[0053] It should be noted that in the present embodiment, the side of the aluminum ingot trough 3 is a trapezoidal structure, which is made of a high-temperature resistant and structurally stable metal material. The design of this trapezoidal structure is intended to better receive and accommodate the leaked high-temperature aluminum liquid to prevent it from overflowing. The top of the trapezoidal structure is wider, which is convenient for the collection and subsequent treatment of the high-temperature aluminum liquid. In addition, the material selection of the aluminum ingot trough 3 is crucial. Considering the high-temperature characteristics of the high-temperature aluminum liquid, the aluminum ingot trough 3 must be able to withstand extremely high temperatures without deformation or damage. Therefore, it is an ideal choice to use a high-temperature resistant and structurally stable metal material, such as special alloy steel or high-temperature resistant cast iron. These materials not only have excellent high-temperature resistance, but also have good mechanical strength and corrosion resistance, ensuring that the aluminum ingot trough 3 maintains stable performance during long-term use.
[0054] In the specific implementation, the aluminum ingot trough 3 is connected to the furnace base 1 through the starter 4. The starter 4 is responsible for driving the turning action of the aluminum ingot trough 3. When the data collector detects the leakage of high-temperature aluminum liquid, the control module will immediately send a signal to the starter 4, and the starter 4 will respond quickly to drive the aluminum ingot trough 3 to turn to the working position (such as Figure 1 As shown, in this embodiment, it is turned clockwise by 90 degrees to reach a horizontal position) to catch the high-temperature aluminum liquid leaking from the melting furnace 2, thereby effectively preventing the leakage of the high-temperature aluminum liquid.
[0055] A starter 4 is provided on the furnace base 1 and is used to drive the aluminum ingot trough 3 to flip;
[0056] In this embodiment, the starter 4 is a servo motor, and the end of the output shaft of the starter 4 is fixed to one side of the furnace base 1 through a fixed plate 5. The aluminum ingot trough 3 is fixed to the output shaft of the starter 4 by welding, and rotates synchronously with the output shaft of the starter 4. When the data acquisition device detects a leakage signal of high-temperature aluminum liquid, the control module will immediately send a start instruction to the starter 4, and the starter 4 will start quickly, driving the aluminum ingot trough 3 to flip to a preset working position, ensuring that the high-temperature aluminum liquid can be caught in time and safely. In addition, in order to ensure the stability and accuracy of the aluminum ingot trough 3 during the flipping process, the starter 4 adopts a high-precision servo control system. The system can accurately control the rotation angle and speed of the output shaft of the starter 4 according to the instructions of the control module, thereby ensuring that the aluminum ingot trough 3 can accurately flip to the preset working position.
[0057] A data collector is provided on the furnace 2 and is used to collect leakage information of high-temperature aluminum liquid in real time;
[0058] It should be noted that the data collector includes a temperature sensor and a flow sensor, both of which are installed outside the furnace 2 and near the high-temperature aluminum liquid leakage port. The temperature sensor is used to monitor the temperature changes at the leakage port in real time to ensure that the temperature changes caused by the high-temperature aluminum liquid leakage can be accurately captured. The flow sensor is used to monitor the aluminum liquid flow at the leakage port. When the flow rate increases abnormally, it indicates that the high-temperature aluminum liquid may leak. The two sensors work together to collect relevant information about the high-temperature aluminum liquid leakage in real time and accurately, providing reliable data support for subsequent control and processing.
[0059] The control module is connected to the real-time data collector and the starter 4, and is used to control the starter 4 to start when the data collector collects the high-temperature aluminum liquid leakage information, so that the aluminum ingot tank 3 is in a working state.
[0060] It should be noted that in this embodiment, the control module is specifically a programmable logic controller (PLC), which receives temperature data and flow data from the data collector and processes and judges according to a preset logic algorithm. When the PLC determines that the high-temperature aluminum liquid is leaking, it immediately sends a control signal to the starter 4 and the cooling module to achieve rapid flipping of the aluminum ingot slot and the spraying of cooling water. The use of PLC makes the control of the entire safety device more intelligent and automated, and improves the response speed and accuracy.
[0061] In summary, the titanium-aluminum solid-liquid composite casting safety device of this embodiment first collects the temperature data and flow data of the furnace 2 in real time through the temperature sensor and flow sensor installed on the outside of the furnace 2 and near the aluminum liquid leakage port. These data are transmitted to the control module, that is, the programmable logic controller (PLC) in real time. When the PLC receives the temperature data and flow data, it will analyze and process these data according to the preset algorithm. The core of the algorithm is to compare the actual collected temperature data and flow data with the preset safety threshold. If the temperature data exceeds the temperature anomaly index threshold, and the flow data exceeds the flow anomaly index threshold, the PLC will determine it as a high-temperature aluminum liquid leakage event.
[0062] Once it is determined that the high-temperature aluminum liquid is leaking, the PLC will take immediate action. First, it will send a signal to the starter 4, which will quickly drive the aluminum ingot trough 3 to flip to the working position after receiving the signal. This process is automatic and rapid, and is designed to catch the high-temperature aluminum liquid leaking from the furnace 2 as quickly as possible to prevent it from further spreading and causing greater harm.
[0063] At the same time, the PLC will also send a signal to the cooling module. After receiving the signal, the cooling module will start immediately and spray cooling water to the leakage point. The spraying of cooling water can effectively reduce the temperature at the leakage point, prevent the high-temperature aluminum liquid from contacting with water vapor and causing an explosion, and further enhance the protective effect of the safety device. In this embodiment, the use of PLC makes the control of the entire safety device more intelligent and automated. Through preset algorithms and logical judgments, the PLC can accurately and quickly respond to high-temperature aluminum liquid leakage events and take effective measures to deal with them. This not only improves the safety of the production environment, but also greatly protects the life safety of operators.
[0064] As an optional embodiment of the present invention, optionally, the data collector collects the high-temperature aluminum liquid leakage information including:
[0065] S1, setting the data collector at the high-temperature aluminum liquid leakage port of the melting furnace 2;
[0066] It should be noted that in step S1, in order to ensure that the signal of high-temperature aluminum liquid leakage can be accurately captured, the data acquisition device is set at the high-temperature aluminum liquid leakage port of the melting furnace 2. The selection of this position is based on the physical characteristics generated when the high-temperature aluminum liquid leaks, such as temperature changes and flow anomalies, which can be most directly detected at the leakage port.
[0067] S2, collecting temperature data and flow data in real time through the temperature sensor and flow sensor on the data collector respectively;
[0068] It should be noted that in step S2, the temperature sensor and flow sensor continuously monitor the state of the furnace 2 to ensure that any slight temperature change or flow fluctuation can be captured immediately. The temperature sensor, with its high sensitivity and accuracy, can quickly respond to the temperature changes caused by the leakage of high-temperature aluminum liquid and provide key temperature data for the control module. The flow sensor accurately monitors the flow of aluminum liquid. Once the flow rate increases abnormally, it is regarded as an early warning signal of high-temperature aluminum liquid leakage.
[0069] S3. Compare the collected temperature data and flow data with their respective preset safety thresholds. When both the temperature data and the flow data exceed their respective safety thresholds, it is determined that there is a leakage of high-temperature aluminum liquid, and a signal of the high-temperature aluminum liquid leakage information is sent to the control module.
[0070] It should be noted that in step S3, the control module receives temperature data and flow data from the data collector, which are the key basis for judging whether the high-temperature aluminum liquid has leaked. A set of rigorous logic algorithms is preset inside the control module, which can quickly and accurately analyze and process the received data. When the temperature data and flow data exceed the preset safety threshold at the same time, the control module will immediately respond, determine it as a high-temperature aluminum liquid leakage event, and then trigger a series of emergency response measures.
[0071] As an optional embodiment of the present invention, optionally, determining the leakage of high-temperature aluminum liquid in step S3 includes:
[0072] S301, calculating a temperature sliding average based on the collected temperature data; calculating a flow sliding average based on the flow data;
[0073] S302, calculating the temperature sliding standard deviation based on the temperature sliding average; calculating the flow sliding standard deviation based on the flow sliding average;
[0074] S303, calculating a temperature anomaly index based on a temperature sliding standard deviation; calculating a flow anomaly index based on a flow sliding standard deviation;
[0075] S304, setting a temperature anomaly index threshold and a flow anomaly index threshold, and determining that high-temperature aluminum liquid is leaking when the temperature anomaly index is greater than the temperature anomaly index threshold and the flow anomaly index is greater than the flow anomaly index threshold.
[0076] It should be noted that based on the above steps S301, S302, S303 and S304, this judgment method not only improves the accuracy of high-temperature aluminum liquid leakage detection, but also effectively avoids false alarms and missed reports. The calculation of the temperature sliding mean and the flow sliding mean can smooth data fluctuations and reduce the impact of accidental factors on the detection results. The calculation of the temperature sliding standard deviation and the flow sliding standard deviation can reflect the degree of change of the data and provide a basis for the calculation of the abnormal index. By setting reasonable temperature abnormal index thresholds and flow abnormal index thresholds, the control module can accurately judge high-temperature aluminum liquid leakage events and take corresponding emergency response measures in a timely manner. The application of this method further enhances the safety and reliability of the present invention.
[0077] As an optional embodiment of the present invention, optionally, the expression for calculating the temperature anomaly index is:
[0078]
[0079] in, represents the sliding average of temperature, W represents the time window size, t represents the total time period, i represents the time point, T(i) represents the temperature data at time point i, σ T (t) represents the sliding standard deviation of temperature, T(t) represents the temperature data changing with time t, I T (t) represents the temperature anomaly index;
[0080] The expression for calculating the flow anomaly index is:
[0081]
[0082]
[0083] in, represents the flow sliding average, F(i) represents the flow data at time point i, σ F (t) represents the flow sliding standard deviation, F(t) represents the flow data changing with time t, and I F (t) represents the flow anomaly index.
[0084] As an optional embodiment of the present invention, optionally, the safety device further includes:
[0085] The temperature reduction module is connected to the control module and is disposed on the melting furnace 2, and is used for spraying cooling water to the leakage point when the high-temperature aluminum liquid leaks.
[0086] It should be noted that in the present embodiment, the cooling module is installed on the furnace 2. In the present embodiment, specifically, the cooling module is a water mist injection system, which includes a water pump, a water storage tank, a water pipe and a water mist nozzle. When the PLC determines that the high-temperature aluminum liquid is leaking, it will immediately send a signal to the cooling module. After the cooling module receives the signal, the high-pressure water pump starts quickly, draws cooling water from the water storage tank, and transports the water to the water mist nozzle through the water pipe. The water mist nozzle can atomize water into fine droplets and spray it to the leakage point at high speed. This high-pressure water mist injection system can not only effectively reduce the temperature at the leakage point, but also quickly cover the surface of the high-temperature aluminum liquid to form a protective layer to prevent the high-temperature aluminum liquid from directly contacting with water vapor to cause an explosion accident. At the same time, due to the coverage of water mist, the heat radiation of the high-temperature aluminum liquid to the surrounding environment can also be reduced, further reducing the degree of harm of the accident.
[0087] As an optional embodiment of the present invention, optionally, the control module controls the starter 4 and the cooling module including:
[0088] S4. When the control module receives the high-temperature aluminum liquid leakage information, it controls the furnace 2 to stop working;
[0089] It should be noted that in step S4, the primary task of the control module is to ensure personnel safety and prevent the situation from escalating. Therefore, once the information of high-temperature aluminum liquid leakage is received, the control module will immediately send instructions to the furnace 2 to stop all work-related operations, including heating, stirring, etc., to avoid further leakage of high-temperature aluminum liquid or aggravation of the leakage. This step is a key link in the emergency response process, which aims to cut off the possibility of high-temperature aluminum liquid leakage from the source and gain valuable time for subsequent processing work.
[0090] S5, the control module controls the starter 4 to start, so that the aluminum ingot trough 3 is quickly turned to the working position of the furnace 2 to catch the high-temperature aluminum liquid leaking from the furnace 2;
[0091] It should be noted that in step S5, the control module sends a command to the starter 4 through precise calculation and logical judgment. After the starter 4 receives the command, the servo motor inside it responds quickly and the output shaft starts to rotate. This rotation is transmitted to the aluminum ingot slot 3 through the fixed plate 5 and the welding connection, so that the aluminum ingot slot 3 can be flipped to the working position of the furnace 2 at a preset angle and speed. The entire flipping process is smooth and rapid, ensuring that the aluminum ingot slot 3 can catch the high-temperature aluminum liquid leaking from the furnace 2 in the shortest time, effectively preventing the further spread of the high-temperature aluminum liquid and potential safety risks.
[0092] S6. The control module controls the cooling module to start and spray cooling water to the leakage point.
[0093] It should be noted that in step S6, after confirming the leakage of high-temperature aluminum liquid, the control module will immediately send a start signal to the cooling module. When the cooling module receives the signal, the water pump of the water mist injection system inside it will start immediately to extract a large amount of cooling water from the water tank. The cooling water is quickly transported to the water mist nozzle through the water pipe. The water mist nozzle uses high pressure to atomize water into extremely fine droplets and sprays them to the leakage point at a very high speed. This high-pressure water mist can not only quickly reduce the temperature at the leakage point to prevent the high-temperature aluminum liquid from causing explosions and other dangerous situations, but also effectively cover the surface of the high-temperature aluminum liquid to form a protective barrier to isolate the high-temperature aluminum liquid from direct contact with water vapor, further enhancing the protection effect of the safety device. At the same time, the coverage of water mist can also significantly reduce the thermal radiation of the high-temperature aluminum liquid to the surrounding environment, reducing the potential threat of accidents to personnel and equipment.
[0094] As an optional embodiment of the present invention, optionally, the time taken for the leaked high-temperature aluminum liquid to fall to the working position of the aluminum ingot slot 3 is greater than the time taken for the control module to control the aluminum ingot slot 3 to rotate to the working position.
[0095] It should be noted that this design ensures that the aluminum ingot trough 3 can be quickly in place at the moment of high-temperature aluminum liquid leakage to catch the leaked high-temperature aluminum liquid, thereby minimizing the diffusion of high-temperature aluminum liquid and the harm to the surrounding environment. In order to achieve this goal, this embodiment accurately calculates the flipping speed of the aluminum ingot trough 3 and the response speed of the starter 4. Through simulation experiments and data analysis, the shortest time required for the aluminum ingot trough 3 to flip to the working position is determined, and it is ensured that the control module can send instructions and start the starter 4 in a shorter time. This design not only improves the response speed of the safety device, but also further enhances its reliability and effectiveness in practical applications.
[0096] As an optional embodiment of the present invention, optionally, the expression for calculating the time taken for the high-temperature aluminum liquid to fall to the working position of the aluminum ingot slot is:
[0097]
[0098] Among them, t drop It indicates the time when the aluminum liquid falls, h indicates the height from which the aluminum liquid falls, and g indicates the acceleration due to gravity;
[0099] The calculation control module controls the time for the aluminum ingot slot 3 to rotate to the working position as follows:
[0100] t total =t accel +t cruise +t decel +t m
[0101]
[0102] Among them, t total Indicates the time it takes for the aluminum ingot slot 3 to rotate to the working position, t cruise Indicates the time of the acceleration stage of the aluminum ingot tank 3, t cruise Indicates the time of the uniform speed stage of the aluminum ingot slot 3, t decel Indicates the time of the deceleration stage of the aluminum ingot tank 3, t m Indicates the control module reaction time, ω accel-end represents the angular velocity of the aluminum ingot slot 3 during the acceleration phase, α accel represents the angular acceleration of the aluminum ingot slot 3 during the acceleration phase, θ cruise represents the angular displacement of the aluminum ingot slot 3 at the uniform speed stage, ω max represents the maximum angular velocity of the aluminum ingot slot 3 in the uniform speed stage, |α decel | represents the angular acceleration of the aluminum ingot slot 3 during the deceleration phase.
[0103] As an optional embodiment of the present invention, optionally, the safety device is provided with at least one data collector.
[0104] It should be noted that, since the aluminum liquid leakage points on different models of furnaces 2 are different, multiple data collectors are set at key parts of the furnace 2 to monitor the status of the furnace more comprehensively. These data collectors are distributed at the leak-prone points, high-temperature areas and key connection parts of the furnace to ensure that no matter where the aluminum liquid leaks, it can be detected immediately. Each data collector has high sensitivity and accuracy, and can collect temperature data and flow data in real time, and quickly transmit these data to the control module. This multi-point monitoring design not only improves the coverage of high-temperature aluminum liquid leakage detection, but also enhances the reliability and response speed of the safety device. In practical applications, this design can more effectively prevent the occurrence of high-temperature aluminum liquid leakage accidents and ensure the safety of personnel and equipment.
[0105] As an optional embodiment of the present invention, optionally, when the number of the data collectors is greater than or equal to two, when the temperature data and flow data collected by one or more of the data collectors exceed their respective safety thresholds, it is determined that the high-temperature aluminum liquid has leaked. This judgment method further improves the accuracy and reliability of the detection of high-temperature aluminum liquid leakage. Due to the complex internal environment of the furnace, a single data collector may be affected by various factors and produce errors. Therefore, by setting up multiple data collectors and conducting comprehensive analysis and judgment on the data collected by them, false alarms and missed alarms can be more effectively avoided. When the temperature data and flow data collected by one or more of the data collectors exceed their respective safety thresholds, the control module will immediately respond, determine it as a high-temperature aluminum liquid leakage event, and initiate corresponding emergency response measures. The application of this multi-point judgment method further enhances the safety and stability of this embodiment, and provides strong support for safety assurance in the high-temperature aluminum liquid casting process.
[0106] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
