Description

Technical Field

[0001] The present invention relates to the technical field of nonferrous smelting related equipment, and in particular to an anti-corrosion intelligent electrode lifting control system and device for a metallurgical furnace. Background Art

[0002] There are many types of electric furnaces used in the field of nonferrous smelting, including electric arc furnaces for smelting concentrates, electric furnaces for slag depletion and slag insulation, electric heating front beds, and sedimentation furnaces for mixed melt sedimentation and separation. Their basic working principles are roughly the same, using electrodes inserted into the slag layer to generate current or arc, and the molten pool current is converted into resistance heat through the molten electric energy. In recent years, nickel-iron smelting furnaces and vanadium-titanium-carbon iron ore smelting furnaces have emerged, which use the characteristics of more concentrated arc heat and higher temperature to accelerate the material smelting speed and improve smelting efficiency. Compared with other smelting furnaces, electric furnaces have the advantages of high thermal utilization rate, small flue gas volume, can be used for smelting of multiple metals, and high total recovery rate of smelted metals, and are developing in the direction of large-scale, high-power, and high-voltage operation. The electrodes face a harsh working environment, not only corrosive erosion from high-temperature flue gas, but also scratching from cold materials and melt bonding, so an electrode protection device is urgently needed. The charge in an electric furnace generally includes a cold material layer, a slag layer and a metal layer. During the smelting process, the addition of cold material will increase the thickness of the slag layer. The electrode is inserted too deeply, resulting in uneven heat distribution in the furnace and crusting on the slag surface. However, as the cold material melts, the thickness of the slag layer gradually decreases, and the height of the metal layer liquid level continues to increase. The immersed part of the electrode is constantly corroded by the high-temperature melt. If the electrode tip is inserted into the metal layer, the electrode corrosion rate will be greatly increased and the current efficiency will be reduced. Therefore, the relative depth of the electrode in the melt is constantly changing. In addition, the highest temperature area of ​​the electric furnace is at the end of the electrode inside the molten pool. When the electrode is inserted too deeply into the slag layer, it is easy to cause damage to the bottom of the furnace, greatly shortening the overhaul cycle of the furnace body. At present, the lifting and lowering of the electrode in the electric furnace is usually controlled manually, which is labor-intensive, complicated, and slow and lagging. The electrode insertion depth cannot be accurately controlled in real time during the smelting process. Therefore, the anti-corrosion intelligent lifting and lowering control of the electrode is urgently needed by the metallurgical industry.

[0003] Prior art 1, Chinese patent, application number 202311023642.9 discloses an electrode replacement device for electric furnace steelmaking; comprising a vertical rod, the upper end face of the vertical rod is rotatably connected with a lifting ring for connecting an external hook, the external hook is connected to a hoist, the outer peripheral surface of the vertical rod is fixedly connected to an anchor hook for hooking the electrode ear, multiple anchor hooks are provided, and are arranged in a circular array on the lower side of the outer peripheral surface of the vertical rod, and the shape of the anchor hook away from one end of the vertical rod is conical; the anchor hook is easier to combine with the surface gap of the ear, and then the crane hook is controlled to move the vertical rod and the anchor hook upward, and the anchor hook can take out the electrode, and then the electrode to be replaced is hung on the anchor hook, and then the crane hook is controlled to place the vertical rod, the anchor hook and the electrode to be replaced in the electric furnace steelmaking, although the function of automatic replacement of electric furnace steelmaking is realized, it is safe and convenient to use, and at the same time, anchor hooks arranged in a circular array are provided at the bottom of the vertical rod, which greatly increases the probability of hooking the electrode ear and saves time. However, the equipment maintenance is more difficult, and the installation and maintenance costs are high.

[0004] Prior art 2, Chinese patent, application number 202111544285.1 discloses an anti-corrosion equalizing electrode for a converter valve, including a stainless steel base, a plastic shell and a stainless steel electrode.

Although the corrosion and deposition rate of the equalizing electrode is greatly reduced. However, sleeved plastic shell will reduce the current efficiency, and may not completely cover all corrosion factors, resulting in unsatisfactory anti-corrosion effect.

[0005] Prior art three, Chinese patent, application number 202210080581.9 discloses a new 3 / 2 electrode arrangement structure for anti-corrosion deposition in a converter valve, including a busbar, an aluminum alloy radiator and a thyristor assembly. Two groups of busbars are arranged, and each group of busbars is equipped with equalizing electrode one, equalizing electrode two and equalizing electrode three. Branch tubes are evenly installed on the busbar and 14 groups are arranged. The aluminum alloy radiator is arranged at the connection of the branch tubes on both sides. The thyristor assembly is arranged at the connection of two adjacent groups of aluminum alloy radiators. The equalizing electrode one, the equalizing electrode two, the equalizing electrode three and the aluminum alloy radiator are all connected by wires. Although the leakage current is avoided from flowing through the radiator, the electrochemical corrosion and deposition problems inside the cooling system are solved from the root, and the safe operation of the power transmission system is ensured, the new 3 / 2 electrode arrangement structure for anti-corrosion deposition in the converter valve is provided. However, the equipment maintenance is more difficult, and the installation and maintenance costs are high.

[0006] At present, the existing technologies 1, 2 and 3 have the problems of difficult equipment maintenance, high installation and maintenance costs, and may not fully cover all corrosion factors, resulting in unsatisfactory anti-corrosion effects. Therefore, the present invention proposes an anti-corrosion intelligent electrode lifting control system and device for metallurgical furnaces, and installs a silicon carbide ceramic sleeve on the top of the electric furnace. The sleeve, booster air pump and sealing device prevent the high-temperature flue gas from scouring and corroding the part of the electrode in the furnace that is not inserted into the melt. In addition, the present invention also proposes an electrode depth calculation method for measuring the relative depth of the electrode and using visual image monitoring technology in the electrode intelligent lifting system to achieve accurate real-time control of the electrode depth; reduce the electrode corrosion rate, improve current efficiency, effectively protect the furnace bottom and extend the furnace overhaul cycle, help enterprises improve production efficiency, reduce production costs, and achieve energy conservation and emission reduction, cost reduction and efficiency improvement.

[0024] As a further improvement of the present invention, the second acquisition module further includes:

[0025] When the calculated height change is less than or equal to 0, and the remaining descending stroke is greater than the absolute value of the height change, the lifting cylinder drives the upper brake to descend by the absolute value of the height change; when the remaining stroke is less than the absolute value of the height change, the lifting cylinder stroke is adjusted;

[0026] When adjusting the stroke of the lifting cylinder, the holding force of the lower brake increases, the upper brake releases, the lifting cylinder drives the upper brake to 1 / 2 of the stroke, then the holding force of the upper brake increases, and the lower brake releases;

[0027] After the lifting cylinder stroke is adjusted, the electrode lifting process continues. After the lifting is completed, the clamping force of the clamping ring increases, and after the set time, the next slag surface height collection process begins.

[0069] like Figure 4 As shown, this embodiment also provides an embodiment of an anti-corrosion intelligent electrode lifting control method. In this embodiment, the anti-corrosion intelligent electrode lifting control method is applied to the anti-corrosion intelligent electrode lifting control device in the above embodiment. The anti-corrosion intelligent electrode lifting control method specifically includes the following steps:

[0071] Step S2: Set to collect the slag surface height once every certain period of time, then calculate the height change, adjust the clamping force of the clamping ring, and collect the remaining ascending stroke and the remaining descending stroke of the lifting cylinder; if the height change is less than zero, when the remaining descending stroke is greater than the absolute value of the height change, the lifting cylinder drives the upper brake to descend by the absolute value of the height change; when the remaining stroke is less than the absolute value of the height change, adjust the lifting cylinder stroke, specifically: increase the clamping force of the lower brake, release the upper brake, the lifting cylinder drives the upper brake to 1 / 2 of the stroke, then increase the clamping force of the upper brake, and release the lower brake;

[0072] Step S3: After the lifting cylinder stroke is adjusted, the electrode lifting process continues; after the lifting is completed, the clamping force of the clamping ring increases, and after a period of time, the next slag surface height collection process begins.

[0073] Preferably, step S1 of this embodiment ensures the stability of the electrode during the insertion process, and prevents the electrode from being offset or shaking during the insertion process; keeps the conductive copper tile in slight contact with the electrode, and ensures that the electrode or copper tile will not be damaged due to excessive clamping force during the electrode insertion process; accurately controls the insertion depth of the electrode to ensure that the electrode can reach the expected operating position; provides a reference point for height change measurement to ensure the accuracy of height measurement; ensures that the electrode and the conductive copper tile fit closely to improve the conductivity efficiency and stability. Step S2 monitors the change of the slag surface height in real time to ensure that the operating environment of the electrode is always within the controllable range; dynamically adjusts the clamping force according to the change of the slag surface height to ensure that the electrode can remain stable at different heights; ensures that the lifting cylinder has sufficient travel margin during the adjustment process to avoid operation failure due to insufficient travel; adjusts the operation of the lifting cylinder according to the remaining travel to ensure that the electrode can accurately drop to the required height, and at the same time ensures the stability and safety of the electrode by adjusting the brake force. After the lifting cylinder stroke is adjusted in step S3, the electrode lifting process continues to be executed to ensure that the electrode can continue to work normally after the adjustment to avoid operation interruption caused by stroke adjustment; after the lifting is completed, the clamping force of the clamping ring is increased to ensure that the electrode can be stably fixed after the lifting is completed to prevent the electrode from loosening or shifting during operation; after a period of time, the next slag surface height collection process is entered to continuously monitor the changes in the slag surface height to ensure that the operating environment of the electrode is always in the best state.

[0074] In summary, this embodiment ensures the stability and safety of the electrode in a corrosive environment by precisely controlling the insertion depth of the electrode and dynamically adjusting the clamping force and lifting stroke. This not only improves the service life and conductive efficiency of the electrode, but also reduces the operational risks caused by unstable electrodes, thereby improving the reliability and operational efficiency of the entire system.

[0075] In step S1 of this embodiment, the upper brake is tightened and the lower brake is released to ensure the stability of the electrode during the lifting process; the clamping ring is loosened but some clamping force is retained to keep the conductive copper tile in contact with the electrode and prepare for current transmission; the lifting cylinder descends and inserts the electrode to achieve accurate insertion of the electrode; the slag surface height is collected and set to 0 to provide a reference for the change in slag surface height; the clamping force of the clamping ring is increased to make the conductive copper tile fit closely with the electrode to ensure the current transmission efficiency; step S2 regularly collects the slag surface height and calculates the change to monitor the dynamic change of the slag surface; adjusts according to the height change The clamping force of the clamping ring and the stroke of the lifting cylinder are used to achieve precise control of the electrode lifting; when the remaining formation is insufficient, the clamping force of the upper and lower brakes is adjusted to improve the stability of the electrode and the continuity of the lifting; after the lifting cylinder stroke is adjusted in step S3, the electrode lifting process is continued to be executed so that the electrode is lifted and lowered according to the predetermined requirements; after the lifting is completed, the clamping force of the clamping ring is increased to consolidate the contact between the electrode and the conductive copper tile, and prepare for the next lifting; enter the next collection process to realize the cyclic operation of the system; allow manual intervention and manual control, which improves the operability and emergency handling capabilities of the system.

[0076] In this embodiment, the upper brake is first tightened and the clamping force is set to N1, the lower brake is released, that is, the clamping force is 0, and the clamping ring is loosened but retains part of the clamping force N 2 Make sure that the conductive copper tile can still fit the electrode, the lifting cylinder descends and inserts the electrode into the predetermined depth H, collect the slag surface height A at this time, and set the slag surface height at this time to 0 (if A>0, it means the slag surface is raised, and A<0, it means the slag surface is lowered). Then the clamping ring is clamped, and the clamping force is N 2 Increase to the set value N 3 Make the conductive copper tile fit tightly with the electrode. Set each interval t, collect the slag surface height A once, and then calculate Δh=A-ηt (where η is the corrosion rate perpendicular to the electrode surface in the slag layer, and η under different furnace types and smelting conditions can be determined experimentally), and adjust the clamping force of the clamping ring to N 2 , collect the remaining ascending stroke D and the remaining descending stroke d of the lifting cylinder. If △h>0, when the remaining ascending stroke D is greater than △h, the lifting cylinder drives the upper brake to ascend by △h; if △h<0, when the remaining descending stroke d is greater than |△h|, the lifting cylinder drives the upper brake to descend by |△h|; when the remaining stroke is less than |△h|, adjust the stroke of the lifting cylinder, specifically: the clamping force of the lower brake is increased to N 1, the upper brake is released, the lifting cylinder drives the upper brake to 1 / 2 stroke, and then the upper brake holding force increases to N 1 , the lower brake is released; the lifting cylinder stroke is adjusted and the electrode lifting process is continued. After the lifting is completed, the clamping force of the clamping ring increases to N 3 , and after time t, the next A acquisition process is entered. In the intelligent electrode lifting control system, human intervention and manual control of each actuator can be performed (see the attached schematic for the specific schematic diagram). Fig.10 ).

[0077] During the smelting process of the electric furnace of this embodiment, if the electrode lifting amplitude is too large, it will seriously affect the stability of the molten pool. If the electrode lifting frequency is too low, it will be difficult to adapt to the furnace conditions that change at any time. Therefore, the time t and △h need to be set according to different furnace types and smelting conditions, generally 5 to 10 seconds, △h is generally set to 10 to 20 mm, and the electrode lifting speed for electrodes with a diameter greater than 1 meter is generally 3 to 8 mm per second, and the electrode lifting speed for electrodes with a diameter less than 1 meter is 6 to 13 mm per second. The electrode stroke depends on the liquid level fluctuation and the insertion depth, and is generally 1.2 to 1.6 meters.

[0078] To sum up, the silicon carbide ceramic sleeve of this embodiment can prevent the high-temperature flue gas from scouring and corroding the part of the intracranial electrode that is not inserted into the melt, reduce the adhesion of splashing melt, and prevent cold materials such as scrap steel from colliding and scratching the electrode to cause damage to the electrode structure; the intelligent electrode lifting system can accurately control the electrode depth in real time, so that the electrode tip is always at the appropriate depth, reduce the electrode corrosion efficiency, effectively protect the furnace bottom and extend the furnace overhaul cycle, help enterprises improve production efficiency, reduce production costs, achieve energy conservation and emission reduction, and reduce costs and increase efficiency.

[0079] Furthermore, if Figure 5 As shown, step S2 specifically includes:

[0080] Step S21: After collecting the slag surface height and setting it to 0, the clamping ring is clamped to make the conductive copper tile fit closely with the electrode. When the time from the last slag surface height collection is greater than or equal to the set interval time, the slag surface height is collected;

[0081] Step S22: Calculate the product of the collected slag surface height and the corrosion efficiency and interval time perpendicular to the electrode surface in the slag layer to obtain the height change value, adjust the clamping force of the clamping ring, and collect the remaining ascending stroke and remaining descending stroke of the lifting cylinder;

[0082] Step S23: Based on whether the calculated height change value is greater than 0, it is determined whether the lifting cylinder should drive the upper brake to descend or ascend.

[0083] Preferably, in step S21 of this embodiment, the slag surface height is collected and set to 0, a reference height is set, and a reference point is provided for subsequent height change measurement to ensure the accuracy and consistency of height measurement; the clamping ring is clamped to make the conductive copper tile fit closely with the electrode to ensure that the electrode remains stable during the slag surface height change process, and to prevent the electrode from loosening and affecting the conductivity efficiency and safety; when the time from the last slag surface height collection is greater than or equal to the set interval time, the slag surface height is collected, and the slag surface height is collected regularly to ensure real-time monitoring of changes in the electrode surrounding environment and timely adjustment of operating parameters. Step S22 calculates the product of the collected slag surface height and the corrosion efficiency and interval time perpendicular to the electrode surface in the slag layer, and quantifies the corrosion of the electrode in the slag layer by calculating the height change value, providing data support for subsequent adjustments; adjusts the clamping force of the clamping ring, and adjusts the clamping force according to the height change value to ensure that the electrode can remain stable under different corrosion degrees, and to prevent the electrode from loosening or damage due to corrosion; collects the remaining ascending stroke and the remaining descending stroke of the lifting cylinder to ensure that the lifting cylinder has sufficient stroke margin during the adjustment process to avoid operation failure due to insufficient stroke. In step S23, based on whether the calculated height change value is greater than 0, it is determined whether the lifting cylinder should drive the upper brake to descend or ascend, and the operating direction of the lifting cylinder is determined based on the positive or negative height change value, to ensure that the electrode can be accurately adjusted to the required height and maintain the stability of the operating environment; it is determined whether the lifting cylinder should drive the upper brake to descend or ascend, and through precise judgment and adjustment, it is ensured that the electrode can maintain the best working state at different heights, thereby improving operating efficiency and safety.

[0084] In step S21 of this embodiment, the slag surface height is collected and set to 0, providing a reference point for calculating the height change of the slag surface; the clamping ring is clamped to make the conductive copper tile fit tightly with the electrode, so that the current can be efficiently transmitted to the electrode through the conductive copper tile; when the time from the last slag surface height collection is greater than or equal to the set interval time, the slag surface height is collected, which allows the system to periodically monitor the height change of the slag surface and adjust the position of the electrode in time; step S22 compares the current slag surface height with the reference height to obtain the height change of the slag surface, which reflects the corrosion of the electrode in the slag layer; according to the height change value, the system can automatically adjust the clamping force of the clamping ring to adapt to the changes of the electrode during the corrosion process and improve the stability and safety of the electrode; collecting the remaining rising stroke and remaining descending stroke of the lifting cylinder helps the system determine whether the position of the electrode needs to be adjusted, as well as the adjustment range; step S23 determines whether the lifting cylinder should drive the upper brake to descend or ascend according to the height change value.

[0085] In this embodiment, after collecting the slag surface height A and setting it to 0, the clamping ring is clamped, and the clamping force is N 2 Increase to the set value N 3Make the conductive copper tile fit tightly with the electrode. When the time from the last slag surface height collection is greater than or equal to the set interval time t, collect the slag surface height A; calculate the product of the collected slag surface height A and the corrosion efficiency η perpendicular to the electrode surface in the slag layer and the interval time t (Δh=A-ηt), and obtain the height change value Δh. Adjust the clamping force of the clamping ring to N 2 , and collect the remaining ascending stroke D and the remaining descending stroke d of the lifting cylinder; according to whether the calculated height change value Δh is greater than 0, it is judged whether the lifting cylinder should drive the upper brake to descend or ascend (for the specific principle diagram, please refer to the attached Fig.10 ).

[0086] In summary, this embodiment ensures the stability and safety of the electrode in a corrosive environment by regularly collecting the slag surface height, calculating the height change value, and dynamically adjusting the clamping force and lifting stroke. Not only does it improve the service life and conductive efficiency of the electrode, but it also reduces the operational risks caused by electrode instability, thereby improving the reliability and operational efficiency of the entire system.

[0087] Furthermore, if Figure 6 As shown, the process of step S23 determining whether the lifting cylinder should drive the upper brake to descend or ascend specifically includes:

[0088] Step S231: When the calculated height change is less than or equal to 0, and the remaining descending stroke is greater than the absolute value of the height change, the lifting cylinder drives the upper brake to descend by the absolute value of the height change; when the remaining stroke is less than the absolute value of the height change, the lifting cylinder stroke is adjusted;

[0089] Step S232: When adjusting the stroke of the lifting cylinder, the holding force of the lower brake increases, the upper brake is released, the lifting cylinder drives the upper brake to 1 / 2 of the stroke, then the holding force of the upper brake increases, and the lower brake is released;

[0090] Step S233: After the lifting cylinder stroke is adjusted, the electrode lifting process continues to be executed. After the lifting is completed, the clamping force of the clamping ring increases, and after a set time, the next slag surface height collection process begins.

[0091] Preferably, step S231 of this embodiment accurately controls the descent height, and ensures that the lifting cylinder only descends to the required height by calculating the height change to avoid excessive descent; the stroke adjustment mechanism, when the remaining stroke is insufficient to complete the required height change, the system can automatically adjust the stroke of the lifting cylinder to avoid operation failure or equipment damage. Significance: Accurately control the descent height to ensure that the equipment remains stable during operation and reduce errors; through the stroke adjustment mechanism, avoid equipment damage caused by insufficient stroke and extend the service life of the equipment. Step S232 Dynamic adjustment of the brake force When adjusting the stroke of the lifting cylinder, by increasing the clamping force of the lower brake, ensure the stability of the equipment during the adjustment process; the smooth transition of the stroke adjustment is to ensure a smooth transition of the stroke adjustment process by first releasing the upper brake and then increasing the clamping force to avoid impact. Significance: By dynamically adjusting the brake force, ensure the safety of the equipment during the stroke adjustment process and prevent accidents; the smooth transition of the stroke adjustment process reduces equipment vibration and impact, and improves the stability and comfort of operation. Step S233: After the stroke of the lifting cylinder is adjusted, the electrode lifting process is continued to ensure the continuity of the entire operation process; after the lifting is completed, the clamping force of the clamping ring is increased to ensure the stability of the equipment after the operation. Significance: Through the continuity of the process, the operation interruption is reduced and the overall operation efficiency is improved; the clamping force of the clamping ring is increased to ensure the stability of the equipment after the operation is completed, and to prevent the equipment from shifting or being damaged due to looseness.

[0092] In step S231 of this embodiment, when the calculated height change is less than or equal to 0, the system will determine the action of the lifting cylinder according to the relationship between the remaining descent stroke and the absolute value of the height change; if the remaining descent stroke is greater than the absolute value of the height change, the lifting cylinder will drive the upper brake to descend to a corresponding height so that the electrode can accurately descend to the target position; if the remaining stroke is less than the absolute value of the height change, the stroke of the lifting cylinder will be adjusted to avoid excessive descent or damage to the equipment; in step S232, when adjusting the stroke of the lifting cylinder, the system will first increase the clamping force of the lower brake so that the lower brake can stably support the electrode, and then release the upper brake to allow the lifting cylinder to drive the upper brake to move to the position of 1 / 2 stroke, then increase the clamping force of the upper brake, release the lower brake, and complete the stroke adjustment; in step S233, after the stroke of the lifting cylinder is adjusted, the system will continue to execute the electrode lifting process until the lifting is completed. After the lifting is completed, the clamping force of the clamping ring will increase to ensure the stability and safety of the electrode; after the set time, the system will enter the next slag surface height acquisition process to prepare for the next electrode lifting.

[0093] In this embodiment, when the calculated height change △h is less than or equal to 0, and the remaining descending stroke d is greater than the absolute value of the height change |△h|, the lifting cylinder drives the upper brake to descend |△h|; when the remaining stroke is less than |△h|, the lifting cylinder stroke is adjusted; when the lifting cylinder stroke is adjusted, the lower brake holding force increases to N 1 , the upper brake is released, the lifting cylinder drives the upper brake to 1 / 2 stroke, and then the upper brake holding force increases to N 1 , the lower brake is released; the lifting cylinder stroke is adjusted and the electrode lifting process is continued. After the lifting is completed, the clamping force of the clamping ring increases to N 3 , and after the set time t, the next slag surface height A collection process will begin (see the attached schematic for the specific principle diagram). Fig.10 ).

[0094] In summary, this embodiment can improve the accuracy and safety of electrode lifting by precisely controlling the action of the lifting cylinder, avoiding electrode damage or accidents caused by height calculation errors or equipment failures; it can ensure the stability and safety of the electrode during the stroke adjustment process, avoiding problems such as electrode shaking or falling off due to improper stroke adjustment; by increasing the clamping force of the clamping ring, the electrode can be stably placed at the target position after the lifting is completed, and by regularly collecting slag surface height information, the electrode wear and slag surface changes can be monitored in real time, providing accurate data support for the electrode lifting operation. This embodiment ensures the safety, accuracy and efficiency of the lifting cylinder operation through precise control, dynamic adjustment and process continuity. Each step is designed to maximize the protection of the equipment, improve the stability and efficiency of the operation, and thus achieve the best operating effect.

[0095] Furthermore, if Figure 7 As shown, the process of step S23 determining whether the lifting cylinder should drive the upper brake to descend or ascend specifically includes:

[0096] Step S234: when the calculated height change is greater than 0, and the remaining ascending stroke is greater than the height change value, the lifting cylinder drives the upper brake to rise by the height change value; when the remaining stroke is less than the absolute value of the height change, the lifting cylinder stroke is adjusted;

[0097] Step S235: When adjusting the stroke of the lifting cylinder, the holding force of the lower brake increases, the upper brake is released, the lifting cylinder drives the upper brake to 1 / 2 of the stroke, then the holding force of the upper brake increases, and the lower brake is released;

[0098] Step S236: After the stroke adjustment of the lifting cylinder is completed, the clamping force of the clamping ring is increased, and after the set time has passed, the next slag surface height collection process begins.

[0099] Preferably, step S234 of this embodiment accurately controls the rising height. When the calculated height change is greater than 0 and the remaining rising stroke is greater than the height change value, the lifting cylinder can accurately drive the upper brake to rise the height change value to ensure that the height of each rise is consistent with the calculated value; when the remaining stroke is less than the absolute value of the height change, the system will adjust the stroke of the lifting cylinder to avoid operation failure or equipment damage caused by insufficient stroke. Significance: Improve operation accuracy by accurately controlling the rising height to ensure that the equipment can accurately reach the predetermined position during operation, improve the accuracy and safety of operation; prevent insufficient stroke by timely adjusting the stroke to avoid equipment jamming or damage caused by insufficient stroke, and extend the service life of the equipment. Step S235 safe transition, when adjusting the stroke of the lifting cylinder, the lower brake clamping force increases, and the upper brake is released to ensure that the equipment will not accidentally drop during the stroke adjustment process, ensuring the safety of operation; smooth transition, after the lifting cylinder drives the upper brake to 1 / 2 stroke, the upper brake clamping force increases, and the lower brake is released to achieve a smooth transition, avoiding equipment vibration or instability caused by sudden changes in the brake force. Significance: By increasing the clamping force, it is ensured that the equipment will not move accidentally during the stroke adjustment process, thereby improving the safety of operation; by smooth transition, it is prevented that the equipment will vibrate or become unstable during operation, thereby improving the stability and reliability of operation. After the stroke adjustment of the lifting cylinder in step S236 is completed, the clamping force of the clamping ring is increased to ensure that the equipment will not loosen or shift during operation; after the set time, it enters the next process; after the set time, it automatically enters the next slag surface height collection process to achieve automated operation and improve work efficiency. Significance: By increasing the clamping force, it is ensured that the equipment remains stable during operation to avoid operational failures due to looseness; automated operation, by automatically entering the next process after the set time, it achieves automated operation, reduces manual intervention, and improves work efficiency and consistency of operation.

[0100] In step S234 of this embodiment, the lifting cylinder adjusts the position of the upper brake according to the height change value, so that the upper brake maintains an appropriate distance from the slag surface. If the remaining rising stroke is less than the absolute value of the height change, in order to avoid overlimit, the stroke of the lifting cylinder needs to be adjusted; in step S235, when adjusting the stroke of the lifting cylinder, first fix the equipment by increasing the clamping force of the lower brake. After the upper brake is released, the lifting cylinder drives the upper brake to move to 1 / 2 of the stroke, and then increases the clamping force of the upper brake, releases the lower brake, and completes the adjustment of the position of the upper brake; after the stroke adjustment of the lifting cylinder is completed, the equipment is further fixed by increasing the clamping force of the clamping ring. After waiting for a set time, the equipment stabilizes and enters the next slag surface height collection process.

[0101] In this embodiment, when the calculated height change △h is greater than 0, and the remaining rising stroke D is greater than the height change value △h, the lifting cylinder drives the upper brake to rise by the height change value △h; when the remaining stroke is less than the absolute value of the height change |△h|, the lifting cylinder stroke is adjusted; when the lifting cylinder stroke is adjusted, the lower brake holding force increases to N 1 , the upper brake is released, the lifting cylinder drives the upper brake to 1 / 2 stroke, and then the upper brake holding force increases to N 1 , the lower brake is released; the lifting cylinder stroke is adjusted and the electrode lifting process is continued. After the lifting is completed, the clamping force of the clamping ring increases to N 3 , and after the set time t, the next slag surface height A collection process will begin (see the attached schematic for the specific principle diagram). Fig.10 ).

[0102] In summary, this embodiment enables the upper brake to accurately follow the changes in the slag surface, maintain the stability and work efficiency of the equipment, and avoids equipment damage or operational errors caused by exceeding the travel limit by judging the relationship between the remaining stroke and the height change; the stability of the equipment is ensured by alternating the upper brake and the lower brake, avoiding shaking or instability that may occur during the adjustment process, and improving the accuracy and efficiency of the adjustment by accurately controlling the moving distance of the upper brake; the stability of the equipment after adjustment is improved, providing a reliable basis for the next slag surface height collection, and avoiding collection errors caused by the equipment not being completely stable by setting a waiting time, thereby improving the accuracy of the collection. This embodiment ensures the safety, accuracy and efficiency of the lifting process of the upper brake driven by the lifting cylinder through precise control, safe transition and automated operation, thereby improving the overall performance of the equipment and the reliability of operation.
