Description
Technical Field
[0001] This invention relates to the field of metallurgical furnace accessories, and in particular to an intelligent cantilever metallurgical furnace slag outlet plugging and slag discharge device. Background Technology
[0002] Metallurgy refers to the process and technology of extracting metals or metal compounds from minerals and processing these metals into metallic materials with specific properties through various methods. In recent years, China's metallurgical industry has achieved significant development, with continuously expanding production scale, improving technological levels, and increasing product variety. However, the metallurgical industry also faces some challenges.
[0003] Specifically, in current metallurgical processes, workers often rely on their experience to judge the liquid level and pressure within the furnace, thereby controlling slag discharge and plugging at the slag inlet. This method not only reduces the control precision of the slag discharge and plugging process, affecting metallurgical efficiency and costs, but may also reduce the safety of metallurgical operations.
[0004] The prior art disclosed in CN106440824B is a water-cooled sliding slag outlet for a metallurgical waste slag smelting furnace. By adopting a water-cooled cast copper structure, it has high strength, high thermal conductivity and fast heat dissipation. The sliding contact surface is machined to have high flatness, good fit clearance and long service life. After long-term use, it solves the problems of low service life, low fit accuracy and poor safety and reliability of sliding refractory brick slag outlets.
[0005] CN213021007U also discloses a slag plugging and discharging device for molten pool smelting metallurgical slag openings. By setting electrical limit switches, the system can automatically control the slag discharge and slag opening sealing, further realizing automated control, preventing the mechanism from detaching from the equipment, and is simple to operate without the need to constantly monitor the drive process. By installing a water tank connected to a water cooling device, the transmission device can be cooled to prevent stress deformation caused by high temperature and extend its service life. At the same time, the installation of a protective cover can prevent slag from splashing onto the transmission device and drive device and affecting the normal operation of the equipment.
[0006] Despite the aforementioned improvements, the market demand for more efficient and precise control of slag plugging and discharge operations in metallurgical processes remains strong. Therefore, this application proposes an intelligent cantilevered metallurgical slag outlet plugging and discharge device, capable of collecting slag discharge data at the slag outlet in real time during slag discharge and achieving high-precision slag plugging and discharge control based on intelligent analysis of this data. This aims to improve the control accuracy of the entire process, optimize metallurgical efficiency and cost management, and enhance operational safety. Summary of the Invention

[0017] Meanwhile, a method for controlling the slag discharge of an intelligent cantilever metallurgical slag outlet includes the following steps: S1. Initial sealing: During the operation of the metallurgical furnace, the water-cooled alloy plug keeps the slag outlet sealed. S2. Slag discharge start-up: After the metallurgical furnace has been operating for a period of time, it begins to tap iron. The weighing sensor located under the molten iron ladle car collects the weight data of the molten iron and transmits it to the intelligent plugging and discharge processing unit through the molten iron weight acquisition unit. After the intelligent plugging and discharge processing unit obtains that the weight of the molten iron has reached the set value, it controls the pushing structure through the plugging and discharge control unit to drive the water-cooled alloy plug away from the slag opening, thereby opening the slag opening and performing slag discharge operation on the metallurgical furnace. At the same time, the intelligent plugging and discharge processing unit controls the electromagnetic induction structure through the induction start-up control unit to start the electromagnetic induction structure. S3. Verification of induction: After the slag opening is open, the material in the metallurgical furnace will move from the slag opening to the slag ditch and fall. The electromagnetic induction structure senses the material flowing through the slag ditch and transmits the induction signal to the slag discharge status acquisition unit. The slag discharge status acquisition unit processes the induction signal and then transmits it to the intelligent blockage treatment unit. S4. Verification and processing: The intelligent blockage and release processing unit verifies and judges the slag discharge status. S41. When the intelligent plugging and discharge processing unit determines that the material flowing out of the slag channel is molten iron, it determines that the slag discharge time is too early and the slag outlet needs to be blocked immediately, and then directly executes step S8. S42. When the intelligent blockage and discharge processing unit determines that the material flowing out of the slag ditch is slag, and determines that the slag discharge time is accurate, then continue to execute steps S5 to S8. S5. Reset and avoidance: The intelligent plugging and release processing unit controls the reset control unit, which controls the steering seat to move. The steering seat drives the water-cooled alloy plug to reset and avoid through the intelligent base, pushing structure and guiding structure, releasing the space at the slag outlet. S6. Slag discharge sensing: After the slag continues to fall from the slag opening and slag channel for a period of time, the slag gradually decreases, and the intensity of the sensing signal sensed by the electromagnetic induction structure changes in a specific way. Then, the slag discharge status acquisition unit transmits this change data to the intelligent blockage processing unit, and the intelligent blockage processing unit determines that the slag discharge is complete based on the data at this time. S7. Avoidance and recovery: After the intelligent plugging and discharge treatment unit determines that the slag discharge is completed, it controls the reset control unit to control the steering seat. The steering seat drives the water-cooled alloy plug to move through the intelligent base, pushing structure and guiding structure, so that the water-cooled alloy plug moves to the coaxial position with the slag outlet. S8. Re-sealing: The intelligent plugging and releasing treatment unit controls the plugging and releasing control unit to move the push structure to move the water-cooled alloy plug into the slag opening and re-seal the slag opening; at the same time, the intelligent plugging and releasing treatment unit shuts down the electromagnetic induction structure through the induction start-up control unit.
[0018] Compared with the prior art, the advantages of this invention are: (1) This scheme, through the combination of electromagnetic induction structure and intelligent plugging and releasing control system, can accurately identify the substances released at the slag opening and slag channel, effectively prevent molten iron from escaping from the slag opening, thereby ensuring the safety of the slag release control process. On the other hand, it can sense the release of slag in real time and quickly trigger the slag plugging action, reduce the waste of resources caused by continuous opening, significantly improve the accuracy of slag plugging and releasing control and the overall operating efficiency of the metallurgical furnace. In addition, by using the reset control unit to implement flexible avoidance control of the water-cooled alloy plug, sufficient space can be reserved for the slag discharge operation, making the layout of the water-cooled alloy plug more scientific and reasonable, ensuring the smooth operation of the metallurgical furnace, and thus greatly enhancing the level of automation and intelligent management in the slag plugging and releasing process.
[0019] (2) In the process of intelligent control of slag blocking and discharge, the addition of monitoring and verification functions for the slag discharge process can significantly improve the safety of slag discharge operation in metallurgical furnaces. At the same time, this improvement can also effectively enhance the accuracy of slag blocking and discharge control, significantly reduce energy consumption during the operation of metallurgical furnaces, improve metallurgical efficiency, and thus bring higher economic benefits. In addition, it also promotes the automation and intelligence of the slag blocking and discharge process, reduces the need for manual intervention, not only improves working environment conditions and reduces the labor intensity of workers, but also greatly reduces the risk of safety accidents such as deflagration caused by high-temperature molten slag splashing or oxygen backfire. By reducing operational deviations and resource waste caused by human factors, it further ensures the smooth progress of metallurgical production. Attached Figure Description

[0022] The technical solution will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.
[0023] First implementation method: Please see Figure 1 and Figure 3 - Figure 9 The intelligent cantilever metallurgical slag outlet plugging and slag discharge device includes an intelligent base 1 and a slag outlet 8. A steering seat 2 is installed on the upper end of the intelligent base 1, and a column 3 is installed on the upper end of the steering seat 2. A pushing structure 5 is set on the right end of the column 3, and a guide structure 6 is set on the pushing structure 5. A water-cooled alloy plug 7 that cooperates with the slag outlet 8 is set at the front end of the guide structure 6. The water-cooled alloy plug 7 is conical in shape, and functional grooves are opened on the outer conical surface of the water-cooled alloy plug 7. The functional grooves are distributed in a spiral shape, which can improve the water-cooling effect of the water-cooled alloy plug 7. A slag groove 81 located below the water-cooled alloy plug 7 is fixedly connected to the rear end of the slag outlet 8. An electromagnetic induction structure 9 is embedded at the left end of the slag groove 81. The electromagnetic induction structure 9 is installed in the slag groove 81 near the reset and avoidance direction of the water-cooled alloy plug 7. This can ensure the safety and stability of the wiring harness connection between the electromagnetic induction structure 9 and the intelligent base 1, and also avoid the impact of the wiring harness connection on the slag discharge operation space. The intelligent base 1 is equipped with an intelligent blocking and releasing control system, which includes an intelligent blocking and releasing processing unit. The input end of the intelligent blocking and releasing processing unit is connected to an iron weight acquisition unit and a slag discharge status acquisition unit. The output end of the intelligent blocking and releasing processing unit is connected to a blocking and releasing control unit, a sensing start control unit, and a reset control unit. The input terminal of the molten iron weight acquisition unit is connected to the signal of the weighing sensor installed under the molten iron ladle car. The molten iron weight acquisition unit achieves wireless signal connection with the weighing sensor through a local area network or wireless network. The input terminal of the slag discharge status acquisition unit is connected to the signal of the electromagnetic induction structure 9. The output terminal of the blocking and releasing control unit is connected to the signal of the pushing structure 5. The output terminal of the induction start-up control unit is connected to the signal of the electromagnetic induction structure 9. The output terminal of the reset control unit is connected to the signal of the steering seat 2. Through the cooperation of the electromagnetic induction structure 9 and the intelligent blocking and releasing control system, the substances released at the slag opening 8 and slag ditch 81 can be precisely controlled. The system accurately identifies and effectively prevents molten iron from escaping from the slag outlet 8, thus ensuring the safety of the slag discharge control process. On the other hand, it can sense the release of slag in real time and quickly trigger the slag blocking action, reducing resource waste caused by continuous opening and significantly improving the accuracy of slag discharge control and the overall operating efficiency of the metallurgical furnace. In addition, the reset control unit can flexibly avoid the water-cooled alloy plug 7, which can reserve sufficient space for the slag discharge operation, making the layout of the water-cooled alloy plug 7 more scientific and reasonable, ensuring the smooth operation of the metallurgical furnace, and thus greatly enhancing the level of automation and intelligent management in the slag discharge process.
[0024] Please see Figure 4 - Figure 6 The electromagnetic induction structure 9 includes a protective shell 91 embedded in the slag trough 81. The protective shell 91 is made of heat-resistant stainless steel (preferably 310 stainless steel). An E-type iron core 92 is fixedly installed inside the protective shell 91. The opening of the E-type iron core 92 is set to the right. The E-type iron core 92 includes a crossbar fixed to the left inner wall of the protective shell 91. A center rod is fixedly connected to the middle of the right end of the crossbar. Side rods are fixedly connected to both the front and rear ends of the crossbar. An excitation coil 94 is wound around the outer end of the center rod, and a detection coil 93 is wound around the outer end of the side rod. A high-temperature resistant wire harness 96 is fixedly connected to the left end of the protective shell 91. The output end of the induction start-up control unit is connected to the excitation coil 94 via the high-temperature resistant wire harness 96, and the input end of the slag discharge status acquisition unit is connected to the detection coil 93 via the high-temperature resistant wire harness 96. Through the cooperation of the E-type iron core 92, the detection coil 93, the excitation coil 94, and the slag discharge status acquisition unit, the intelligent plugging and discharge processing unit can effectively assist the intelligent plugging and discharge processing unit in sensing and identifying the substances released from the slag opening 8 and the slag channel 81 based on the different magnetic properties of slag, molten iron, and air, as well as the changes in the magnetic field generated by the detection coil 93 on the excitation coil 94. This not only helps to accurately determine the key nodes for controlling the plugging and discharge of slag opening and ensure the safety of the slag discharge process, but also significantly improves the control accuracy of the plugging and discharge operation, thereby promoting the improvement of the metallurgical furnace operation efficiency and reducing its metallurgical cost.
[0025] It should be noted that the electromagnetic induction structure 9 primarily achieves its inductive monitoring function by measuring the electrical conductivity of substances. In the metallurgical industry, molten iron, as a metallic melt, is a good conductor with very high electrical conductivity; slag, as a silicate melt, is an insulator with very low electrical conductivity; and air, as an ideal insulator, has an electrical conductivity that can be approximated as zero. Therefore, from the perspective of electrical conductivity, the conductivity of molten iron is much greater than that of slag, and both are higher than that of air. This allows the electromagnetic induction structure 9 to effectively distinguish between these different substances.
[0026] Specifically, when the induction start-up control unit energizes the excitation coil 94, it works in conjunction with the neutral rod to generate a stable alternating magnetic field. Due to the overall design of the E-type iron core 92, the detection coil 93 can sensitively sense changes in the magnetic field generated by the excitation coil 94. The slag discharge status acquisition unit amplifies, filters, and demodulates this signal, ultimately converting it into a standardized and easily identifiable electrical signal (here, it is set to convert to a voltage signal). Subsequently, the intelligent blockage treatment unit makes corresponding analyses and judgments based on these electrical signal data transmitted from the slag discharge status acquisition unit. When molten iron flows inside the slag trough 81, given that molten iron is an excellent conductor of electricity, it creates strong eddy currents in the area where the excitation coil 94 is located. These eddy currents further generate a strong reverse magnetic field, which significantly weakens the original magnetic field strength generated by the excitation coil 94, causing the voltage value induced by the detection coil 93 to drop sharply to a low level. Subsequently, the data processed by the slag discharge status acquisition unit is transmitted to the intelligent plugging and releasing processing unit. Based on the received low voltage signal, the intelligent plugging and releasing processing unit can confirm the presence of a highly conductive substance—that is, molten iron—currently flowing inside the slag trough 81, and thus determine that there is an abnormality in this slag discharge process. When slag flows inside 81, the slag itself has good insulating properties and hardly generates eddy current effects, thus causing minimal magnetic field interference to the excitation coil 94. However, it is worth noting that although the impact is slight, the flowing slag may still carry away some heat, causing a slight and slow change in the temperature of the head of the protective shell 91. This thermal effect may subtly change the resistance characteristics of the excitation coil 94 or the working state of the neutral rod, causing a certain fluctuation in the voltage value detected by the detection coil 93. In this case, the detection coil 93 will capture a relatively stable but high voltage signal. Similarly, this information is converted by the slag discharge status acquisition unit and transmitted to the intelligent plugging and discharge processing unit. Based on the received stable high voltage signal, the intelligent plugging and discharge processing unit can confirm the current situation and determine that there is an insulating medium flowing inside the slag groove 81, that is, there is insulating material—slag—flowing inside the slag groove 81, indicating that normal slag discharge operation is underway. When the slag trough 81 is filled only with air, since air is a near-perfect insulator, it hardly induces any form of eddy current. Therefore, the alternating magnetic field released by the excitation coil 94 can propagate without obstruction. At this time, the detection coil 93 can accurately detect a reference voltage value within the middle range. Based on such a constant reference voltage signal input, the intelligent plugging and releasing unit can react quickly, indicating that the slag trough 81 is currently in an unloaded state, with no substantial material moving inside. Therefore, as time progresses until the slag discharge is nearing its end, with the remaining slag gradually decreasing, the intelligent plugging and releasing unit will continuously receive fluctuation signals of the reference voltage signal and the high voltage signal. Once such alternating fluctuation signal characteristics are detected, it means that it is time to initiate the slag plugging operation to ensure safety. Therefore, the intelligent plugging and releasing unit will control the water-cooled alloy plug 7 to produce the corresponding slag plugging action.
[0027] Please see Figure 4 - Figure 6 The protective shell 91 extends to the inside of the slag trench 81 at its right end and is fixedly connected to a ceramic spacer 95. The right end face of the ceramic spacer 95 is flush with the inner wall of the slag trench 81. The protective shell 91 is filled with a high-temperature insulating material, which can be any one of magnesium oxide powder, ceramic wool, and special high-temperature resistant cement. The high-temperature insulating material can effectively fix the E-type iron core 92, detection coil 93, and excitation coil 94. It not only prevents loosening and provides good insulation performance, but also conducts the heat generated inside to the protective shell 91, thereby enhancing the cooling effect of the subsequent water cooling system. This ensures the safety and stability of the E-type iron core 92, detection coil 93, and excitation coil 94 in long-term use and significantly improves their durability.
[0028] Please see Figure 1 , Figure 3 , Figure 7 and Figure 8 A water-cooled alloy plug 7 has a water-cooled cavity 73 inside. A water-cooled circulation pipe assembly 72 is fixedly connected to the rear end of the water-cooled cavity 73. A water-cooled shell is fitted on the outer end of the protective shell 91. A water-cooled auxiliary pipe assembly is installed inside the water-cooled shell and wound around the outside of the protective shell 91. The output of the intelligent plugging and discharge treatment unit is also connected to a water-cooled circulation control unit. The output of the water-cooled circulation control unit is connected to the water-cooled circulation system located at the rear of the intelligent base 1. The water-cooled circulation system is connected to the water-cooled circulation pipe group 72 and the water-cooled auxiliary pipe group through a splitter. Through the cooperation of the water-cooled circulation control unit, the water-cooled circulation system, the water-cooled circulation pipe group 72 and the water-cooled auxiliary pipe group, effective cooling and protection of the water-cooled alloy plug 7 and the electromagnetic induction structure 9 can be achieved. This not only prevents the water-cooled alloy plug 7 from being damaged due to overheating during the plugging process, but also avoids damage to the electromagnetic induction structure 9 caused by heat accumulation during monitoring and induction. This significantly improves the durability of the water-cooled alloy plug 7 and the electromagnetic induction structure 9. At the same time, it also ensures good plugging effect and induction accuracy, providing a strong guarantee for the stable operation of the plugging and discharge control process.
[0029] It should be noted that the water-cooled circulation system is an existing mechanical component, which is directly referenced here without any changes to its structure and principle. Those skilled in the art can select it according to actual needs. For example, the water-cooled circulation system includes components such as water pump, heat exchanger, deionized water tank, filter, valve and control instrument. The output end of the water-cooled circulation control unit is connected to the water pump, the distributor and the corresponding valves respectively. It can use the water pump to transport the deionized water in the deionized water tank to the water-cooled circulation pipe group 72 and the water-cooled auxiliary pipe group through the distributor, and respectively control the water-cooled alloy plug 7 and the electromagnetic induction structure 9 for water-cooled circulation. Specifically, the water-cooled circulation pipe assembly 72 is responsible for delivering deionized water to the water-cooled chamber 73 so that heat exchange can be performed when the water-cooled alloy plug 7 is in a blocked state. Then, it is sent to the heat exchanger through the water-cooled circulation pipe assembly 72, and finally returned to the deionized water tank after being treated by the filter, thus completing the water-cooled circulation process for the water-cooled alloy plug 7. The deionized water flowing in the water-cooled auxiliary tube assembly will perform heat exchange on the protective shell 91. After the heat exchange is completed, it flows into the heat exchanger, and after being filtered by the filter, it flows back to the deionized water tank, thus achieving the purpose of water cooling circulation for the protective shell 91. The water-cooled circulation control unit has the ability to independently control the water-cooled circulation pipe group 72 and the water-cooled auxiliary pipe group through the distributor. This allows the water-cooled circulation control unit to implement separate water-cooled control for the water-cooled alloy plug 7 and the electromagnetic induction structure 9, thereby ensuring the safety of both during application. This will not be elaborated further here.
[0030] Please see Figure 1 , Figure 3 , Figure 7 and Figure 8The pushing structure 5 includes a pushing cover 51, with pushing liner plates 53 fixedly connected to both the front and rear ends of the pushing cover 51, and a pushing hydraulic rod 52 fixedly installed on the upper end of the pushing cover 51 between the two pushing liner plates 53. The guide structure 6 includes multiple guide rods 61. Multiple guide rods 61 are slidably connected between two push liner plates 53. The rear end of the guide rod 61 extends to the outside of the push liner plate 53 located on the rear side and is fixedly connected to a rear push plate 62. The front end of the guide rod 61 extends to the outside of the push liner plate 53 located on the front side and is fixedly connected to a front push plate 63. An assembly plate 71 is fixedly connected to the front end of the front push plate 63. A water-cooled alloy plug 7 is fixedly connected to the front end of the assembly plate 71. The movable end of the push hydraulic rod 52 extends to the outside of the push liner 53 located at the rear and is fixedly connected to the rear push plate 62. The output end of the plugging control unit is connected to the push hydraulic rod 52. Through the cooperation of the plugging control unit and the push hydraulic rod 52, the movement of the water-cooled alloy plug 7 in the axial direction of the slag opening 8 can be precisely controlled, thereby realizing the effective management of the plugging operation at the slag opening 8. This not only improves the control efficiency of the plugging process but also significantly enhances its accuracy. In addition, the design of the guide rod 61 provides guiding constraints for the water-cooled alloy plug 7, further ensuring the accuracy and stability of the movement of the water-cooled alloy plug 7, reducing mechanical wear, and effectively extending the service life of the water-cooled alloy plug 7.
[0031] Please see Figure 1 , Figure 3 , Figure 7 and Figure 8 The right end of the column 3 is hinged to a lifting arm 41 and a lifting hydraulic rod 4 located on the upper side of the lifting arm 41. The lower end of the lifting hydraulic rod 4 is hinged to the middle of the upper end of the lifting arm 41. A push cover 51 is fixedly installed on the right end of the lifting arm 41. The output end of the reset control unit is connected to the lifting control unit. The output end of the lifting control unit is connected to the lifting hydraulic rod 4. Through the cooperation of the lifting control unit and the lifting hydraulic rod 4, the water-cooled alloy plug 7 can be effectively lifted and controlled, further enhancing its avoidance performance and reducing the space occupied by the water-cooled alloy plug 7 at the slag outlet 8. This helps to optimize the subsequent slag discharge operation process and ensure the safety and reliability of the metallurgical furnace operation.
[0032] Please see Figure 2 and Figure 9The steering seat 2 includes an outer ring seat fixedly installed on the upper end of the intelligent base 1. A drive housing is fixedly connected to the rear end of the outer ring seat and communicates with it. An inner ring seat is rotatably connected to the inner wall of the outer ring seat. The upper end of the inner ring seat is fixedly connected to the column 3. A steering gear is fixedly connected to the outer end of the inner ring seat. A worm gear meshing with the steering gear is rotatably connected inside the drive housing. A steering motor is fixedly installed at the front end of the drive housing. The front end of the worm gear extends to the outside of the drive housing and is fixedly connected to the output shaft of the steering motor. The output end of the reset control unit is connected to the steering control unit. The output end of the steering control unit is connected to the steering motor signal. Through the cooperation of the steering control unit and the steering motor, the steering control of the water-cooled alloy plug 7 can be realized, directly guiding the water-cooled alloy plug 7 to avoid the slag outlet 8 and move it to a safe area, thereby fully releasing the space required for slag discharge and ensuring the safe operation of subsequent slag discharge.
[0033] Please see Figure 2 The input end of the intelligent plugging and releasing unit is also connected to a metallurgical parameter setting unit and an instruction receiving unit. The input ends of both the metallurgical parameter setting unit and the instruction receiving unit are connected to the data port signal set on the intelligent base 1. The output end of the intelligent plugging and releasing unit is also connected to a plugging and releasing feedback unit and an abnormality warning unit. The output end of the plugging and releasing feedback unit is connected to the data port signal set on the intelligent base 1, and the output end of the abnormality warning unit is connected to the alarm signal set on the intelligent base 1. Through the setting of the metallurgical parameter setting unit and the instruction receiving unit, the intelligent plugging and releasing control system can achieve collaborative work with the metallurgical furnace. This not only facilitates the control of the plugging and releasing process according to the actual operating status of the metallurgical furnace, but also enables interaction with the staff, ensuring the controllability of the entire process. Furthermore, through the setting of the plugging and releasing feedback unit and the abnormality warning unit, plugging and releasing data can be output, and an alarm signal can be issued immediately when any abnormality is detected, thereby helping the staff to quickly take emergency measures and ensure the safety of the metallurgical furnace operation.
[0034] It should be noted that the intelligent base 1 is equipped with multiple data ports, which can be connected to mobile devices, metallurgical furnace control systems, control buttons, and metallurgical monitoring platforms. This not only enables the input of metallurgical parameters and control commands, but also allows for the feedback and output of slag discharge and plugging data. This facilitates real-time viewing and adjustment of relevant parameters by staff, thereby ensuring the accuracy of subsequent plugging and control and guaranteeing the safety of metallurgical operations.
[0035] Please see Figure 1 - Figure 9Operators input relevant parameters into the metallurgical parameter setting unit via the data port. These parameters include total metallurgical output, rated furnace efficiency, and single tapping weight. The metallurgical parameter setting unit converts these parameters and transmits them to the intelligent blockage handling unit. The intelligent blockage handling unit calculates and processes the parameters to determine the data required for subsequent control.
[0036] Then, during the operation of the metallurgical furnace, the operator transmits the metallurgical start command to the command receiving unit via the data port. The command receiving unit then transmits the command to the intelligent plugging and releasing unit. The intelligent plugging and releasing unit controls the reset control unit, causing the reset control unit to issue control commands to the steering control unit and the lifting control unit respectively. The steering control unit controls the steering motor to rotate, which in turn drives the intelligent base 1 to rotate via the steering seat 2, causing the water-cooled alloy plug 7 to gradually approach the slag opening 8. The lifting control unit controls the lifting hydraulic rod 4, causing the lifting hydraulic rod 4 to act on the lifting arm 41, which, through the pushing structure 5, causes the water-cooled alloy plug 7 to descend and move to the same position as the slag opening 8. At the shaft position, the intelligent plugging and releasing unit synchronously controls the plugging and releasing control unit and the water-cooling circulation control unit, so that the plugging and releasing control unit controls the retraction of the push hydraulic rod 52. The moving end of the push hydraulic rod 52 retracts, causing the rear push plate 62 to move forward. Then, the rear push plate 62 pushes the front push plate 63 forward through the guide rod 61, so that the front push plate 63 drives the water-cooled alloy plug 7 to gradually move into the slag opening 8 through the assembly plate 71, and performs the slag plugging function of the slag opening 8. The water-cooling circulation control unit acts on the water-cooling circulation system, and through the cooperation of the water-cooling circulation pipe group 72 and the water-cooling cavity 73, the water-cooled alloy plug 7 in the blocked state is protected by water-cooling circulation.
[0037] After the metallurgical furnace has been operating for a period of time, molten iron is released into the molten iron ladle car through the tapping spout. The weighing sensor located under the molten iron ladle car monitors the weight of the molten iron in real time and transmits the data to the intelligent plugging and discharge unit through the molten iron weight acquisition unit. When the intelligent plugging and discharge unit determines that the weight of the molten iron is about to reach the set value (which can be limited to 70% to 80% of the weight of a single tap), it determines that the state of slag discharge is reached. Then, the plugging and discharge control unit controls the push hydraulic rod 52, causing the movable end of the push hydraulic rod 52 to extend. Under the linkage and guidance of the rear push plate 62, guide rod 61, front push plate 63 and assembly plate 71, the water-cooled alloy plug 7 is driven to detach from the slag outlet 8, realizing the slag discharge action of the slag outlet 8.
[0038] Meanwhile, the intelligent plugging and discharge treatment unit also controls the water-cooling circulation system through the water-cooling circulation control unit. While ensuring the continuous water-cooled circulation of the water-cooled alloy plug 7, it also circulates and cools the inside of the protective shell 91 through the water-cooled auxiliary pipe group. This prevents the material flowing on the slag ditch 81 from causing thermal damage to the internal components of the protective shell 91, ensuring the safe and effective operation of the detection coil 93 and the excitation coil 94. It also energizes the excitation coil 94 set on the slag ditch 81 through the induction start-up control unit, so that the excitation coil 94 can generate a magnetic field. When slag is discharged from the slag outlet 8, the material in the metallurgical furnace flows out through the slag ditch 81. The detection coil 93 senses the change in the magnetic field of the excitation coil 94, and then transmits the sensed data to the intelligent plugging and discharge treatment unit through the slag discharge status acquisition unit. The intelligent plugging and discharge treatment unit judges and verifies the material flowing through the slag ditch 81 at this time. When the substance is determined to be molten iron, it is identified as premature slag discharge anomaly. Subsequently, the intelligent plugging and discharge handling unit performs two operations: First, it controls the push hydraulic rod 52 through the plugging and discharge control unit to re-seal the slag outlet 8 with the water-cooled alloy plug 7; second, it transmits the abnormal data to the data port through the plugging and discharge feedback unit, so that the staff can observe it in time, and activate the alarm through the abnormality warning unit to issue a warning reminder, thereby improving the efficiency of abnormality handling; at the same time, it controls the excitation coil 94 to cut off the power through the induction start-up control unit, and shuts down the control of the water-cooled circulation system on the water-cooled auxiliary pipe group through the water-cooled circulation control unit, so as to save energy and water resources. When the substance is determined to be slag, the slag discharge is deemed effective. The intelligent plugging and discharge handling unit issues reset and avoidance commands to the lifting control unit and the steering control unit through the reset control unit. This causes the lifting control unit to control the lifting hydraulic rod 4 to move. Through the linkage of the lifting arm 41 and the pushing structure 5, the water-cooled alloy plug 7 is driven to rise. The steering control unit controls the steering motor. Through the linkage of the steering seat 2, the intelligent base 1, and the pushing structure 5, the water-cooled alloy plug 7 is driven to move away from the slag outlet 8, leaving sufficient space for subsequent slag discharge operations and ensuring the safety of subsequent slag discharge operations. After the reset control unit drives the water-cooled alloy plug 7 to reset and avoid, the intelligent plugging and discharge handling unit controls the water-cooled circulation control unit to shut off the water-cooled circulating water to the water-cooled circulation pipe group 72, thereby reducing energy consumption and saving water resources.
[0039] When the slag release at slag outlet 8 reaches its final stage, the slag flow gradually decreases and becomes interrupted. The detection coil 93 transmits the fluctuating data it senses to the intelligent plugging and releasing unit through the slag discharge status acquisition unit. This allows the intelligent plugging and releasing unit to determine that the slag plugging point has been reached. Subsequently, the reset control unit controls the lifting control unit and the steering control unit respectively. The steering control unit moves the water-cooled alloy plug 7 to a position close to slag outlet 8 via the steering motor. The lifting control unit moves the water-cooled alloy plug 7 down to a position coaxial with slag outlet 8 via the lifting hydraulic rod 4. The intelligent plugging and releasing unit then synchronously controls the plugging and releasing control unit and the water-cooled circulation control unit. This causes the plugging and releasing control unit to retract the pushing hydraulic rod 52, moving the water-cooled alloy plug 7 into slag outlet 8 to re-seal slag outlet 8. The water-cooled circulation control unit then controls the water-cooled circulation system, using the cooperation of the water-cooled circulation pipe group 72 and the water-cooled cavity 73 to provide water-cooled circulation protection for the water-cooled alloy plug 7. Finally, the intelligent blocking and releasing unit will also disconnect the current flowing into the excitation coil 94 through the sensing start-up control unit, turn off the function of the excitation coil 94, and control the water cooling circulation system through the water cooling circulation control unit to stop the water cooling auxiliary pipe group from cooling the protective shell 91, so as to achieve the purpose of energy saving and water saving.
[0040] Second implementation method: Please see Figure 2 This embodiment is an improvement on the first embodiment. As an optional functional application, the slag plugging and discharge control method of the intelligent cantilever metallurgical slag outlet plugging and discharge device includes the following steps: S1. Initial sealing: During the operation of the metallurgical furnace, the water-cooled alloy plug 7 keeps the slag outlet 8 sealed. S2. Slag discharge start-up: After the metallurgical furnace has been operating for a period of time, the metallurgical furnace begins to tap iron. The weighing sensor located under the molten iron ladle car collects the weight data of the molten iron and transmits it to the intelligent plugging and discharge processing unit through the molten iron weight acquisition unit. After the intelligent plugging and discharge processing unit obtains that the weight of the molten iron has reached the set value, it controls the pushing structure 5 through the plugging and discharge control unit, which drives the water-cooled alloy plug 7 away from the slag opening 8, thereby opening the slag opening 8 and performing slag discharge operation on the metallurgical furnace. At the same time, the intelligent plugging and discharge processing unit controls the electromagnetic induction structure 9 through the induction start-up control unit, thereby activating the electromagnetic induction structure 9. S3. Verification of induction: After the slag opening 8 is in the open state, the material in the metallurgical furnace will move from the slag opening 8 to the slag trough 81 and fall down. The electromagnetic induction structure 9 senses the material flowing through the slag trough 81 and transmits the induction signal to the slag discharge status acquisition unit. The slag discharge status acquisition unit processes the induction signal and then transmits it to the intelligent blockage treatment unit. S4. Verification and processing: The intelligent blockage and release processing unit verifies and judges the slag discharge status. S41. When the intelligent blocking and discharge processing unit determines that the material flowing out of the slag ditch 81 is molten iron, it determines that the slag discharge time is too early and the slag outlet 8 needs to be blocked immediately, and then directly executes step S8. S42. When the intelligent blockage and discharge processing unit determines that the material flowing out of the slag ditch 81 is slag, it determines that the slag discharge time is accurate, and then continues to execute steps S5 to S8. S5. Reset and avoidance: The intelligent blockage treatment unit controls the reset control unit, which controls the steering seat 2 to move. The steering seat 2 drives the water-cooled alloy plug 7 to reset and avoid through the intelligent base 1, the pushing structure 5 and the guiding structure 6, releasing the space at the slag outlet 8. S6. Slag discharge sensing: After the slag continues to fall from the slag opening 8 and slag channel 81 for a period of time, the slag gradually decreases, and the intensity of the sensing signal sensed by the electromagnetic induction structure 9 changes in a specific way. Then, the slag discharge status acquisition unit transmits this change data to the intelligent blocking and discharge processing unit. The intelligent blocking and discharge processing unit judges that the slag discharge is completed based on the data at this time. S7. Avoidance and recovery: After the intelligent plugging and discharge treatment unit determines that the slag discharge is completed, it controls the reset control unit to control the steering seat 2 to move. The steering seat 2 drives the water-cooled alloy plug 7 to move through the intelligent base 1, the pushing structure 5 and the guiding structure 6, so that the water-cooled alloy plug 7 moves to the coaxial position with the slag outlet 8. S8. Re-sealing: The intelligent plugging and releasing unit controls the plugging and releasing control unit, causing the pushing structure 5 to move the water-cooled alloy plug 7 into the slag opening 8 to re-seal the slag opening 8. Simultaneously, the intelligent plugging and releasing unit shuts down the electromagnetic induction structure 9 through the induction start-up control unit. During the intelligent control of slag plugging and releasing, a monitoring and verification function for the slag releasing process is added, which can significantly improve the safety of slag releasing operations in metallurgical furnaces. At the same time, this improvement can also effectively enhance the accuracy of slag plugging and releasing control, significantly reduce energy consumption during the operation of metallurgical furnaces, improve metallurgical efficiency, and thus bring higher economic benefits. In addition, it promotes the automation and intelligence of the slag plugging and releasing process, reduces the need for manual intervention, not only improves working environment conditions and reduces the labor intensity of workers, but also greatly reduces the risk of safety accidents such as deflagration caused by high-temperature molten slag splashing or oxygen backfire. By reducing operational deviations and resource waste caused by human factors, the smooth operation of metallurgical production is further guaranteed.
