The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0038] The following describes the slag slow cooling full process control system, method, electronic device and storage medium of the embodiment of the present application with reference to the accompanying drawings. In view of the related technologies mentioned in the above background technology center, employees must carry handheld operators to operate on the vehicle, the working environment of employees is poor, the labor intensity is high, the cooling time needs to rely on experience judgment and manual on-site measurement, there are subjective deviations, it is easy to cause slag type deterioration, affect the flotation effect, the manual intervention rate is high, and the labor efficiency and economic benefits are low.

This solves the problem that in related technologies, employees must hold a handheld operator to operate the vehicle, their working environment is poor, the labor intensity is high, the cooling time needs to rely on experience and manual on-site measurement, there are subjective deviations, and it is easy to cause slag type deterioration, affect flotation effect, have a high rate of manual intervention, and low labor efficiency and economic benefits.

[0039] Specifically, Figure 1 This is a schematic structural diagram of a slag slow cooling full-process control system 10 provided in an embodiment of the present application.

[0040] like Figure 1As shown, the slag slow cooling full-process control system 10 includes: a transportation component 100, a lifting component 200 and a cooling component 300.

[0041] Specifically, the transport assembly 100 is used to carry the slag bag, receive the slag from the slag opening, transport it along the track to the slag slow cooling field, and transport the empty slag bag back to the position corresponding to the slag opening.

[0042] It can be understood that, different from the manual control method of the related art, the embodiment of the present application can automatically control the movement of the transport component, so that the slag bag carrying slag is received from the slag mouth and transported along the track to the slag slow cooling field without manual operation.

[0043] Specifically, the embodiment of the present application can carry the slag bag from the slag opening through the transport component 100, and then transport it along the track to the slag slow cooling field. After the slag bag is emptied, the empty slag bag can be put back on the transport component 100 through the lifting component 200, and then transported to the corresponding position of the slag opening again. The embodiment of the present application can avoid manual intervention in the entire process, thereby improving labor efficiency and economic benefits.

[0044] Optionally, in one embodiment of the present application, the transport assembly 100 includes: an electric flat car, an on-board unit, a main control unit, and a remote control center.

[0045] Among them, the on-board unit and the main control unit are used to control the movement of the electric flat car according to the dispatching instructions and send the position information.

[0046] The remote control center is used to receive location information and generate dispatch instructions for the electric flat car to receive slag from the slag outlet, transport it along the track to the slag slow cooling field, and re-transport the empty slag bag to the corresponding position of the slag outlet.

[0047] It can be understood that the embodiments of the present application can issue dispatch instructions through a remote control center such as a remote operation platform, receive data analysis and display from the on-board unit and the main control unit, and perform automatic control, collect data from the flat car PLC through wireless communication, and issue control commands.

[0048] For example, the embodiment of the present application can realize the precise positioning of the electric flat car through the combination of "travel encoder + RFID (Radio Frequency Identification) tag positioning technology + reflector laser positioning technology". Among them, the encoder can be used for the rough positioning of the electric flat car, and the position of the flat car can be displayed in real time on the interface. In addition, an RFID card reader can be installed on the car, and an RFID tag can be installed at a key position of the flat car running track. When the flat car passes the tag, the card reader collects the tag position and the controller can display the running track and position coordinates of the electric flat car on the display in real time. At the same time, this positioning system can also be used to calibrate the position information of the original system, thereby solving the problem of disordered position information of the original system. Furthermore, the embodiment of the present application can detect key position information by laser scanning the reflector installed on the ground, and make real-time corrections to the current travel speed and position of the flat car.

[0049] The embodiment of the present application can transfer slag bags through an intelligent process without the need for employees to operate the vehicle, thereby reducing the labor intensity of employees and improving labor efficiency and economic benefits.

[0050] The lifting assembly 200 is used to lift the slag bag arriving at the slag slow cooling field to the cooling bag position, and lift the cooled slag bag to the slag pouring pool to pour it out to obtain an empty slag bag.

[0051] It is understandable that transporting the slag bag to the cooling bag for slow cooling can eliminate white spots in the steel and avoid cracks caused by thermal stress and structural stress during the re-cooling process.

[0052] In the actual implementation process, the embodiment of the present application can lift the hot slag bag to the designated bag position through the lifting assembly 200. After the smelted slag in the slag bag is completely solidified, it is lifted to the slag pouring pool and poured out to obtain an empty slag bag, thereby improving the intelligence of the equipment, reducing the work intensity of employees, and improving production efficiency.

[0053] Optionally, in one embodiment of the present application, the lifting assembly 200 includes: a metallurgical gantry crane and a crane control system.

[0054] Among them, the crane control system is used to control the metallurgical gantry crane to perform automatic bag picking, automatic bag placing and automatic slag dumping actions on the slag bag, so as to lift the slag bag to the cooling bag position, and lift the cooled slag bag to the slag dumping pool for dumping.

[0055] It can be understood that the automatic control operation technology of the crane can realize the intelligent control of the metallurgical gantry crane with integrated functions such as intelligent positioning, automatic bag picking, automatic bag placing, automatic hooking and automatic slag dumping.

[0056] Specifically, the embodiments of the present application can control the crane to complete the process of automatic bag picking, automatic bag placing, and automatic slag dumping by obtaining real-time and accurate position information. In the process of automatic bag picking, automatic bag placing, and automatic slag dumping, the crane trolley can be moved above the slag bag position to lift the slag bag, wherein the positioning accuracy of the trolley can be less than or equal to 3cm. During the operation of the system, if a slag bag is manually placed by the operator's remote control, there will be a deviation between the position of the slag bag and the position set by the system. If the deviation is greater than 3cm, it will affect the automatic hooking in the automatic control process, and the position of the trolley can be fine-tuned through the operating console handle. If the slag bag is automatically placed by the system, it will not be affected and the slag bag can be automatically hooked.

[0057] The embodiment of the present application can realize automatic control process through the metallurgical gantry crane, improve the interactivity and intelligence of the equipment, and improve production efficiency.

[0058] The cooling assembly 300 is used to cool the slag ladle hoisted to the cooling ladle position until the smelting slag in the slag ladle reaches a preset solidification condition to obtain a cooled slag ladle.

[0059] It is understandable that when the smelting slag reaches the preset solidification conditions, copper mineral particles that can be separated mechanically can be formed, which are significantly different from other slag-forming materials, thereby achieving separation.

[0060] During the actual implementation process, the embodiment of the present application can cool the slag ladle hoisted to the cooling ladle position through the cooling component 300 until the smelting slag in the slag ladle reaches a certain solidification condition such as the smelting slag temperature reaches room temperature, thereby obtaining a cooled slag ladle, thereby improving the intelligence level of the equipment, eliminating safety risks on site, and reducing the workload of employees.

[0061] Optionally, in one embodiment of the present application, the cooling assembly 300 includes: a cooling unit and a control unit.

[0062] Wherein, the cooling unit is used to cool the slag bag.

[0063] The control unit is used to control the operation of the cooling unit according to the actual temperature of the slag ladle and the actual slow cooling time based on the smelting slag temperature change model and the slag ladle temperature change model corresponding to the current season.

[0064] It is understandable that the temperature changes of the smelting slag and the slag bag vary according to the season, so it is necessary to accurately control the cooling process according to the influence of the season on the temperature change parameters.

[0065] Specifically, the embodiment of the present application can cool the slag ladle through the cooling unit, and can detect the temperature of the slag ladle through sensors and other detection devices, and establish a smelting slag temperature change model through the control unit in consideration of different seasonal conditions. Combined with the slag ladle temperature change model, valves are added on site to achieve one-to-one intelligent control of a single slag ladle spray system, and the valves are automatically opened and closed in combination with the slow cooling time and the temperature of the slag ladle, without the need for manual opening and closing of valves on site, thus achieving intelligent operation of the slag slow cooling process, eliminating safety risks on site, and improving production efficiency.

[0066] Optionally, in one embodiment of the present application, the cooling unit includes a spray water cooling system.

[0067] It can be understood that by using the spray water cooling method, the various parts of the high-temperature object can be cooled evenly, and the heat can be dissipated through flow, thereby achieving a better cooling effect.

[0068] The embodiment of the present application can evenly cool the slag bag and improve production efficiency by using a cooling unit such as a spray water cooling system.

[0069] Optionally, in one embodiment of the present application, the cooling assembly 300 further includes: a state management unit.

[0070] The status management unit is used to identify the actual status of all cooling ladle positions in the slag ladle area of ​​the slow cooling field to display the actual status of each cooling ladle position.

[0071] For example, the embodiment of the present application can number each slag bag position based on the on-site slag bag layout through the status management unit, determine the slag bag number through the position information of the crane, and then determine the bag position status information through the movement state of the crane, the crane weighing system and the slag bag temperature detection system. The implementation of the present application can display the status information of each slag bag position in real time on the upper computer interface, and manually configure the status of each slag bag position in abnormal situations, thereby improving the intelligence of the slag slow cooling process, improving production efficiency, and reducing employee workload.

[0072] The classification of packet position status will be described in detail below.

[0073] Optionally, in one embodiment of the present application, the actual state is one of an empty state, an empty package state, an air-cooled state, and a water-cooled state.

[0074] Here, the classification of the bag position status is illustrated. Among them, the actual status of the cooling bag position may include but is not limited to the empty state, empty bag state, air-cooled state and water-cooled state. When the main hoist of the crane rises and the weight is greater than 10 tons and less than 70 tons, the control algorithm will set the slag bag position to an empty state; if the weight is greater than 70 tons, it indicates that the weight sensor is abnormal. When the main hoist of the crane descends and the weight is less than 30 tons, the control algorithm will set the slag bag position to an empty state; if the weight is greater than 70 tons, it indicates that the weight sensor is abnormal. When the main hoist of the crane descends, the weight is greater than 30 tons and less than 70 tons, and the temperature is greater than 200°C, the control algorithm will set the slag bag position to an air-cooled state; if the weight is greater than 70 tons, it indicates that the weight sensor is abnormal. When the slag bag position is in an air-cooled state, if the slag bag temperature is less than 200°C and the air-cooling time is greater than 4 hours, the control algorithm will automatically turn on the spray water of the slag bag position and set the slag bag position to a water-cooled state.

[0075] The embodiment of the present application can monitor the actual status of the cooling bag position in real time, thereby recording the bag position status information of each slag bag, completing the slag bag scheduling management work, and improving the intelligence of the system.

[0076] Combine the following Figure 2-Figure 10 As shown, the slag slow cooling full-process control system 10 of the embodiment of the present application is described in detail with a specific embodiment.

[0077] The embodiment of the present application can be divided into three modules and can be implemented through 5G (5 th The fifth generation mobile communication technology) communication system links the three modules to establish a full-process intelligent slag slow cooling process, among which the three modules can specifically include:

[0078] S201: Intelligent electric flat car.

[0079] It is understandable that the electric flat car intelligent control system is mainly composed of a remote control center, a main control PLC (Programmable Logic Controller), and a vehicle-mounted PLC. The remote operation platform is responsible for issuing dispatch instructions and receiving data analysis and display from the vehicle-mounted unit and the control console control unit and performing automatic control. It collects data from the flat car PLC through wireless communication and issues control commands. Among them, the control system UI (User Interface) interface can be as follows Figure 3 As shown, the automation process can be Figure 4 shown.

[0080] The embodiment of the present application can realize the precise positioning of the electric flat car through the combination of "travel encoder + RFID tag positioning technology + reflective plate laser positioning technology". The encoder is used for the rough positioning of the electric flat car, and the position of the flat car is displayed in real time on the interface. The embodiment of the present application can install an RFID reader on the car, and install an RFID tag at a key position on the flat car running track. When the flat car passes the tag, the card reader collects the tag position and can display the electric flat car running track and position coordinates on the display in real time through the intelligent calculation of the controller. This positioning system can also solve the problem of disordered position information of the original system, and can be used as Figure 5 As shown in the figure, this positioning system is used to calibrate the position information of the original system. Figure 6 As shown, by laser scanning the reflective plate installed on the ground to detect key position information, the current travel speed and position of the flat car can be corrected in real time.

[0081] In addition, the embodiment of the present application can read the original flat car control system data, process its control program, integrate it into the slag slow cooling full-process control system, and link the electric flat car with the crane to ensure safe and reliable operation.

[0082] S202: Intelligent gantry crane.

[0083] like Figure 7 As shown, the automatic control operation technology of the crane in the embodiment of the present application can realize intelligent control of the metallurgical gantry crane, integrating functions such as intelligent positioning, automatic bag picking, automatic bag placing, automatic hooking and automatic slag dumping.

[0084] Among them, the encoding ruler sensor and the motor absolute encoder can be combined to form a dual positioning system. By comparing the position information fed back by the two position sensors, the accuracy of the positioning system can be judged in real time, thereby realizing the precise positioning of the crane trolley, car, main hook and auxiliary hook. There is no cumulative error, and there is no error caused by track and wheel wear.

[0085] When the crane trolley is running, the embodiment of the present application can feed back the measurement value generated by the detection to the crane control system, and the control system uses the sequential data to correct and apply the position data to form a closed-loop feedback control, so that the crane reaches the specified position. Due to the fixation of the encoder and the detection sensor, the position detection of the trolley and the carriage is realized as absolute displacement, without cumulative errors, and errors caused by track and wheel wear, so it can meet the precise requirements of positioning accuracy of ≤±5mm.

[0086] By obtaining real-time and accurate position information, the embodiment of the present application can control the crane to complete the process of automatic bag picking, automatic bag placing, and automatic slag dumping. In the process of automatic bag picking, automatic bag placing, and automatic slag dumping, the crane trolley will move above the slag bag position and lift the slag bag. The positioning accuracy of the trolley is ≤3cm. During the operation of the system, if a slag bag is manually placed by the operator's remote control, there will be a deviation between the position of the slag bag and the position set by the system. If the deviation is greater than 3cm, it will affect the automatic hooking in the automatic control process, which requires fine-tuning the position of the trolley through the console handle. If the slag bag is automatically placed by the system, it will not be affected and the slag bag can be automatically hooked.

[0087] In addition, the embodiments of the present application can be Figure 8 As shown in the figure, a complete video monitoring system and database are established to assist in automated operation, making it convenient for employees to remotely monitor the automated operation status of equipment in the main control room, realize system status monitoring, fault self-diagnosis and alarm, and reduce the difficulty of equipment maintenance.

[0088] S203: Intelligent water spraying.

[0089] The embodiment of the present application can establish a smelting slag temperature variation model by detecting the temperature of the slag bag and considering different seasonal conditions. By combining the slag bag temperature variation model, adding valves on site, realizing one-to-one intelligent control of a single slag bag spray system, and automatically opening and closing the valves in combination with the slow cooling time and the temperature of the slag bag, without the need for manual opening and closing of the valves on site, such as Fig. 9 shown.

[0090] Furthermore, the embodiment of the present application can realize the slag bag state management, automatically identify all the empty spaces, empty bags and full bags in the slow cooling area of ​​the slag bag, and can Fig.10 As shown, a process system diagram is established to realize information visualization, and the status information of each bag position, slag bag, valve, instrument and other equipment is reflected on the display screen. The details are as follows:

[0091] First, each slag bag position is numbered according to the on-site slag bag layout, and then the slag bag number is determined by the crane's position information. The bag position status information is determined by the crane's motion status, crane weighing system and slag bag temperature detection system. The bag position status includes: empty position status, empty bag status, air cooling status and water cooling status. The status information of each slag bag position will be displayed on the upper computer interface. In abnormal situations, the status of each slag bag position can be manually configured.

[0092] 1. Empty state: When the crane main hoist rises and the weight is greater than 10 tons and less than 70 tons, the control algorithm will set the slag bag position to an empty state; if the weight is greater than 70 tons, it indicates that the weight sensor is abnormal.

[0093] 2. Empty bag status: When the crane main hoist descends and the weight is less than 30 tons, the control algorithm will set the slag bag position as empty bag status; if the weight is greater than 70 tons, it indicates that the weight sensor is abnormal.

[0094] 3. Air cooling state: When the main hoist of the crane descends, the weight is greater than 30 tons and less than 70 tons, and the temperature is greater than 200°C, the control algorithm will put the slag bag position into air cooling state; if the weight is greater than 70 tons, it indicates that the weight sensor is abnormal.

[0095] 4.
