Description

Technical Field

[0001] This invention relates to the technical field of electrode paste experimental measurement and monitoring, and in particular to an experimental device for simulating abnormal electrode consumption in a submerged arc furnace. Background Technology

[0002] Abnormal electrode consumption in submerged arc furnaces directly impacts smelting efficiency, increases energy consumption, and can even lead to equipment failure. Related simulation experimental devices are crucial for exploring the mechanisms behind this problem and optimizing production processes. Existing simulation experimental devices typically include a basic experimental chamber, a simple electrode simulation structure, and single-parameter monitoring elements. They can preliminarily simulate electrode energization scenarios and provide basic data support for research by monitoring certain physical parameters. These devices are widely used in metallurgical materials research and development and submerged arc furnace operation and maintenance optimization.

[0003] Existing technologies have significant drawbacks: they have a single monitoring dimension, focusing mainly on temperature or electrical parameters, making it difficult to simultaneously capture multi-dimensional coupled features such as pressure, displacement, gas composition, and weight changes, and thus failing to fully reconstruct the complex process of abnormal electrode consumption; this results in poor repeatability of experimental data and limited reference value, making it difficult to meet the research needs for in-depth exploration of the mechanism of abnormal electrode consumption.

When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0032] Example 1 Reference Figures 1-9 This first embodiment of the invention provides a simulation experimental device for abnormal electrode consumption in a submerged arc furnace, comprising an experimental body 100, a monitoring and analysis component 200, and a pressure relief component. The three components work together to achieve accurate simulation of abnormal electrode consumption scenarios in a submerged arc furnace, synchronous monitoring of multi-dimensional parameters, safe pressure relief, and convenient experimental operation. It specifically solves the problems of traditional simulation devices, such as single monitoring parameters, untimely pressure relief, and cumbersome operation connections. At the same time, it takes into account experimental safety and data reliability, greatly improving the realism and experimental efficiency of abnormal electrode consumption simulation, and adapting to the simulation experimental needs of abnormal electrode consumption in submerged arc furnaces under different operating conditions.

[0033] Furthermore, the experimental body 100 is the core simulation unit of the device, providing the main experimental structure of the electrode paste. It is internally sealed and can perform various experiments on different types of electrode paste. In this embodiment, the experimental body 100 includes an experimental box 101, a simulation component 102 disposed inside the experimental box 101, and a top lifting component 103 disposed on the experimental box 101. The top lifting component 103 is used to control the simulation action of the simulation component 102.

[0034] The simulation component 102 is mainly used to energize the electrode paste to simulate actual use scenarios, while the top lifting component 103 is mainly used to control the position of the electrodes and to facilitate the operator to install the electrode paste between the two electrodes.

[0035] Furthermore, an opening and closing door 104 is provided on the experimental chamber 101, and an observation window is provided on the opening and closing door 104. The observation window allows the operator to observe the internal experimental situation. A latch is provided on the opening and closing door 104, which can lock the opening and closing door 104 to the experimental chamber 101.

[0036] Furthermore, in this embodiment, the simulation component 102 includes a lower support frame 1021 disposed within the experimental chamber 101, an upper support frame 1022 slidably connected within the experimental chamber 101, a first electrode 1023 disposed at the upper end of the lower support frame 1021, a second electrode 1024 disposed at the lower end of the upper support frame 1022, and mounting components disposed on the first electrode 1023 and the second electrode 1024. The lower support frame 1021 is generally cylindrical, while the upper support frame 1022 is disposed opposite to the lower support frame 1021 and has the same shape. The first electrode 1023 is connected to the lower support frame 1021 by bolts, and the second electrode 1024 is also connected to the upper support frame 1022 by bolts. The first electrode 1023 and the second electrode 1024 are made of conductive metal and are generally cylindrical. Grooves are provided on the first electrode 1023 and the second electrode 1024 for mounting electrode paste.

[0037] In this embodiment, the mounting member is used to fix the electrode paste inside the first electrode 1023. In this embodiment, the mounting member includes a mounting protrusion disposed inside the first electrode 1023, and a plurality of friction protrusions are provided on the mounting protrusion. When the electrode paste is installed inside the first electrode 1023, the mounting protrusion can restrict the electrode paste.

[0038] The experimental chamber 101 is a sealed structure. The observation window of the door 104 allows for real-time observation of the experimental process without opening the chamber, and avoids interference from the experimental environment. The lower support frame 1021 fixes the first electrode 1023, and the upper support frame 1022 drives the second electrode 1024 to slide, which can simulate the positional changes during the adjustment and consumption of the electrode spacing. The mounting parts ensure that the electrode paste is firmly fixed and prevent it from falling off during the experiment.

[0039] Furthermore, the monitoring and analysis component 200 serves as the core data acquisition unit, enabling synchronous monitoring and analysis of multi-dimensional parameters. In this embodiment, the monitoring and analysis component 200 includes a temperature monitoring module 201, a pressure and displacement monitoring module 202, an electrical parameter monitoring module 203, a gas monitoring module 204, and a weight monitoring module 205, all housed within the experimental chamber 101.

[0040] The temperature monitoring module 201 is an infrared temperature sensor that monitors the internal ambient temperature of the experimental chamber 101, the electrode surface temperature, and the sample center temperature. The pressure and displacement monitoring module 202 is a high-precision pressure sensor and a laser displacement sensor that are used to monitor the electrode contact pressure, the gas pressure inside the furnace, and the downward displacement of the upper electrode, reflecting the electrode consumption rate and sintering state.

[0041] Preferably, the electrical parameter monitoring module 203 is a Hall current sensor and a high-precision voltage transmitter, which are respectively set on the first electrode 1023 and the second electrode 1024. The electrical parameter monitoring module 203 is used to collect the changes in current, voltage and resistivity during the experiment and correlate the conductivity and consumption characteristics of the electrode paste.

[0042] Preferably, the gas monitoring module 204 is an electrochemical oxygen sensor and an infrared gas analyzer; the weight monitoring module 205 is used to monitor the weight change after the electrode is consumed.

[0043] Furthermore, a real-time monitoring and visualization module is also installed on the experimental chamber 101, which can provide experimental personnel with an intuitive status monitoring interface and support real-time intervention.

[0044] A dynamic parameter dashboard is set up on the experimental chamber 101: it displays the real-time changes of core parameters such as temperature, pressure, and current in the form of an instrument panel and trend curves, and supports multi-parameter comparison views; and a remote access submodule is set up: it supports remote viewing of experimental data and equipment status on PC / mobile devices, making it convenient for R&D personnel to track the experimental progress at any time.

[0045] Furthermore, multi-module synchronous monitoring provides more comprehensive data dimensions compared to traditional single-parameter monitoring. It can capture the correlation between temperature gradient, pressure change, electrical parameter fluctuation, gas composition change and weight consumption. Infrared temperature sensors can accurately capture temperature changes during abnormal consumption; laser displacement sensors monitor electrode displacement changes in real time to reflect the consumption rate; Hall current sensors and voltage transmitters accurately collect electrical parameters and capture electrical signal fluctuations during abnormal consumption; gas sensors and analyzers can detect oxygen content and other characteristic gases, and promptly detect abnormal combustion or reaction caused by abnormal consumption.

[0046] Example 2 Reference Figures 1-3 The difference between this embodiment and the previous embodiment is that in this embodiment, the top lifting component 103 includes a bracket 1031 disposed on the upper end of the experimental chamber 101, a downward pressure rod 1032 slidably connected to the bracket 1031, a sliding rod 1033 rotatably connected to the upper end of the downward pressure rod 1032, and a spacer locking member 105 disposed on the upper end of the sliding rod 1033. The bracket 1031 is disposed on the upper end of the experimental chamber 101, and a truss 1034 is disposed on the bracket 1031. A sleeve 1035 is provided on the truss 1034. There are two sleeves 1035, which are slidably connected to the lower pressure rod 1032. At the same time, the lower end of the lower pressure rod 1032 extends into the experimental box 101 and is connected to the upper support frame 1022. A spring is provided between the lowermost sleeve 1035 and the lower pressure rod 1032. One end of the spring is connected to the lowermost sleeve 1035, and the other end is connected to the lower pressure rod 1032. When the lower pressure rod 1032 moves down, it will compress the spring.

[0047] Furthermore, in this embodiment, the spacer locking member 105 includes a first rotating disk 1051 disposed on the bracket 1031, a ratchet 1052 disposed on the first rotating disk 1051, a ratchet 1053 disposed inside the experimental chamber 101 and meshing with the ratchet 1052, a dial 1054 coaxially disposed with the ratchet 1052, and an extension rod 1055 disposed on the dial 1054. The first rotating disk 1051 is fixed to the inner wall of the experimental chamber 101, and the ratchet 1052 is fixedly connected to the first rotating disk 1051. Meanwhile, one end of the ratchet 1053 is provided with a rotation center, so that the ratchet 1053 rotates at a certain angle. A torsion spring is also provided on the ratchet 1053, which will keep the ratchet 1053 meshing with the ratchet 1052. Preferably, both the actuating disk 1054 and the first rotating disk 1051 are arranged vertically, and the extension rod 1055 extends radially from the actuating disk 1054. A chuck 1056 rotates on the first rotating disk 1051, and a mating contact 1057 extends from the chuck 1056 radially. A locking rod 1058 is provided on the mating contact 1057, and the locking rod 1058 is perpendicular to the surface of the mating contact 1057. The mating contact 1057 is provided with a hinge joint 1059 that is hinged to the upper end of the slide bar 1033. The hinge joint 1059 also extends along the vertical direction of the mating contact 1057. The rotation center of the ratchet 1053 is also located on the mating contact 1057. When the actuating disk 1054 rotates, it will contact the locking lever 1058. With the actuation of the locking lever 1058, the locking lever 1058 moves together, thereby causing the chuck 1056 to rotate together, which in turn drives the ratchet 1053 to move together.

[0048] Furthermore, there is a drive unit inside the sealed box that drives the dial 1054 to rotate. In this embodiment, the drive unit includes a motor mounted on the bracket 1031, and the motor drives the dial 1054 to rotate.

[0049] The interval locking component 105, through the cooperation of ratchet 1052 and ratchet 1053, realizes the intermittent lifting and lowering of the pressing rod 1032, which can precisely control the descent amplitude of the electrode, so that the electrode paste can be pressed down intermittently. When the upper support frame 1022 is lifted, the pressing rod 1032 will move up quickly, so that the electrode paste can be removed more quickly.

[0050] Furthermore, an installation frame 300 is provided on the experimental chamber 101. A storage box 301 is rotatably connected to one end of the installation frame 300. A gripping rod 302 is rotatably connected to the end of the installation frame 300 away from the storage box 301. A gripping plate 303 is provided at one end of the gripping rod 302. A storage slot 304 is provided on the storage box 301. A gripping component for gripping electrode paste is provided on the gripping plate 303. A plurality of storage slots 304 are arranged in a circumferential array on the outer peripheral wall of the storage box 301. The gripping rod 302 and the storage box 301 are vertically arranged. An opening 305 for the gripping plate 303 to move out is provided on the side wall of the experimental chamber 101. A sealing passage component is provided on the opening 305. A rotating component 400 for driving the storage box 301 to rotate is provided on the installation frame 300.

[0051] The gripping plate 303 is equipped with gripping components, including a vacuum electrically controlled suction cup, which can be electrically controlled by the operator to grip the electrode paste.

[0052] Some of the electrode paste is stored in the storage tank 304. The storage tank 304 serves to store old electrode paste and supply new electrode paste. The storage tank 304 does not need to be completely filled with new electrode paste when in use. When the gripping rod 302 removes the old electrode paste, it is placed in the storage tank 304 for temporary storage.

[0053] The mounting bracket 300 has two support rods 306 at one end, which are arranged parallel to each other. The gripping rod 302 is mounted on the support rod 306. The slider 307 is rotatably connected to the support rod 306 via a shaft. The gripping rod 302 has an elongated slot 308 for the slider 307 to slide, so that the elongated slot 308 and the slider 307 are slidably connected. The slider 307 is rectangular in shape, which allows the slider 307 to slide in a straight line.

[0054] In this embodiment, the rotating component 400 includes a guide plate 401 disposed on the mounting frame 300, a guide wheel 402 disposed at one end of the storage box 301, an extension rod 403 disposed on the guide plate 401, a mating arc groove 404 formed on the guide wheel 402 that mates with the guide plate 401, and a driving elongated groove 405 formed on the guide plate 401. The guide plate 401 is disposed on one side of the storage box 301 and close to the lower end of the storage box 301. A side frame 406 extends upward from the middle section of the mounting frame 300. A first control rod 407 is rotatably connected to the side frame 406. A second control rod 408 extends from the first control rod 407 and is connected to the gripping rod 302. An angle changing rod 409 is rotatably connected to the first control rod 407.

[0055] Preferably, the guide plate 401 has a disc-shaped structure with a notch formed on it, and the extension rod 403 extends out from the notch of the guide plate 401. The second control rod 408 and the first control rod 407 are both hinged to the side frame 406 and are respectively arranged on both sides of the side frame 406.

[0056] Preferably, in this embodiment, the angle changing rod 409 is hinged to the first control rod 407, and a first support rod 4091 is rotatably connected to the angle changing rod 409. The first support rod 4091 is connected to the rotation center of the guide disk 401, so that the rotation of the guide disk 401 will drive the swing of the first support rod 4091.

[0057] Preferably, a crossbar 4071 is connected between the rotation centers of the two first control rods 407. The storage slot 304 of the storage box 301 can store electrode paste of different specifications. The rotating component 400 drives the storage box 301 to rotate, which, together with the gripping rod 302 and the gripping plate 303, realizes automatic gripping and replacement of electrode paste. The vacuum electronically controlled suction cup is adapted to the shape of the electrode paste and grips it firmly.

[0058] During the rotation of the guide disk 401, the extended support rod 403 extending from its outer edge gradually embeds into the mating arc groove 404 of the guide wheel 402 at the end of the storage box 301. As the guide disk 401 continues to rotate, the extended support rod 403 slides and pushes along the mating arc groove 404, causing the guide wheel 402 to rotate around its own axis through a fixed angle, thereby causing the storage box 301 to rotate synchronously at a fixed angle. For each rotation of the guide disk 401, the extended support rod 403 completes one motion cycle, and the storage box 301 rotates exactly through the working angle of a storage slot 304. At the same time as the guide disk 401 rotates, the drive strip groove 405 on its disk surface drives the angle changing rod 409 to move in conjunction with the first support rod 4091. The first support rod 4091 swings in a plane with the rotation of the guide disk 401, pulling the angle changing rod 409 to move synchronously, thereby driving the first control rod 407 on the side frame 406 to swing outward around the hinge point. The first control lever 407 pulls the gripping lever 302 via the second control lever 408. The gripping lever 302 slides along the slider 307 on the frame 306 and swings outward synchronously, driving the end gripping plate 303 to approach the material picking station of the storage box 301. After the gripping plate 303 is aligned with the electrode paste sample in the storage tank 304, the gripping element starts adsorption to complete the gripping and removal of the failed electrode paste, or to complete the picking and loading of the new electrode paste.

[0059] Furthermore, the present invention also includes a pressure relief component, which is a safety assurance unit to achieve safe pressure relief and sealing of the experimental chamber 101. The sealing component includes a flexible shielding ring disposed on the opening 305 and a cooperating shielding ring disposed on the outer periphery of the gripping plate 303. In this embodiment, the pressure relief component is disposed inside the experimental chamber 101. The pressure relief component includes a pressure relief hole 501 disposed on the side wall of the experimental chamber 101, a pressure relief plug 502 disposed on the pressure relief hole 501, a pressure rod 503 rotatably connected to the pressure relief plug 502, and a first magnetic block 504 disposed at the end of the pressure rod 503. A second magnetic block 505 is disposed on the side wall of the experimental chamber 101. The first magnetic block 504 is slidably connected to the end of the pressure rod 503. The experimental chamber 101 is provided with a magnetization module for controlling the magnetization of the first magnetic block 504. The sealing component includes a flexible shielding ring on the opening 305 and a cooperating shielding ring disposed on the outer periphery of the gripping plate 303.

[0060] The flexible shielding ring works in conjunction with the matching shielding ring to ensure the airtightness of the experimental chamber 101 when the gripping plate 303 enters and exits, preventing experimental gas leakage. When the pressure inside the experimental chamber 101 exceeds the threshold, the first magnetic block 504 can be magnetized by the magnetization module and attracted to the second magnetic block 505, thereby driving the pressure rod 503 to rotate and opening the pressure relief plug 502 to release pressure, preventing equipment damage or experimental interruption caused by pressure accumulation.

[0061] Operation procedure: Open the experimental chamber 101 through the switch door 104, fix the electrode paste inside the first electrode 1023 using the mounting bracket, adjust the upper support frame 1022 to separate the second electrode 1024 from the first electrode 1023; put the spare electrode paste into the storage slot 304 of the storage box 301; start the magnetization module and ensure that the pressure relief component is in standby mode; set the parameter acquisition frequency of the monitoring and analysis component 200.

[0062] Simulation Experiment and Data Monitoring: Activate the top lifting component 103, remove the electrode paste that has already been tested through the interval locking component 105, and then replace it with another electrode paste to continue simulating the electrode consumption process; the monitoring and analysis component 200 synchronously collects data on ambient temperature, electrode surface temperature, sample center temperature, pressure, electrode displacement, current and voltage, gas composition and electrode weight, and records the parameter change characteristics corresponding to abnormal consumption in real time; the experimental status can be observed in real time through the observation window without opening the box for intervention.

[0063] Pressure relief and experimental completion: When the pressure inside the experimental chamber 101 rises abnormally, the gripping plate 303 is first driven to move to the outside of the experimental chamber 101, and the magnetization module is activated, causing the first magnetic block 504 and the second magnetic block 505 to attract each other. The movement of the gripping plate 303 drives the opening of the pressure relief plug 502, thereby relieving the pressure. After the experiment, the top lifting component 103 and the monitoring and analysis component 200 are turned off, and the electrode paste after the experiment is taken out by the gripping rod 302 and the gripping plate 303.
