[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0023] The embodiment of the present invention provides a production control method of a converter, referring to Figure 1 As shown, the method includes the following steps S101 to S103:

[0024] S101: Acquire the detection position of the converter skirt.

[0025] refer to Figure 2 As shown, the converter skirt is arranged above the converter mouth, which can effectively collect the smoke and exhaust gas generated by the converter. At different stages of converter blowing, the skirt needs to be adjusted up and down to make the skirt in a suitable position, thereby ensuring the safe production of the converter.

[0026] In some embodiments, the converter includes an upper limit member and a lower limit member for limiting the position of the skirt. Then, step S101 may include: if an upper limit signal generated by the upper limit member is detected, determining that the detection position is the upper limit position; if a lower limit signal generated by the lower limit member is detected, determining that the detection position is the lower limit position.

[0027] It should be noted that directly obtaining the upper limit signal and the lower limit signal to determine the detection position avoids adding other additional components to determine the detection position, thus reducing the complexity of function implementation, thereby improving the convenience of obtaining the detection position.

[0028] It should be noted that the upper limit part is used to limit the skirt to the upper limit position, which is the highest position of the skirt during the lifting process of the skirt. When the skirt is at the upper limit position, the converter can be controlled to tilt, and the converter mouth will not collide with the skirt when the converter tilts, thereby ensuring the safe production of the converter. The lower limit part is used to limit the skirt to the lower limit position, which is the lowest position of the skirt during the lifting process of the skirt. By setting the lower limit position, the skirt is prevented from falling to an excessively low position and causing the skirt to collide with the mouth, thereby avoiding safety accidents and ensuring the production safety of the converter.

[0029] It should be noted that the detection position may be the upper limit position, the lower limit position, or any intermediate position between the upper limit position and the lower limit position. In addition, if the upper limit member or the lower limit member fails, the detection position may also be a position above the upper limit position or a position below the lower limit position. Finally, the numerical representation of the detection position may use the height of the position relative to the ground, for example, the numerical representation of the upper limit position may be the height of the upper limit position relative to the ground.

[0030] In some embodiments, the upper limit member includes a first upper limit module and a second upper limit module, and the lower limit member includes a first lower limit module and a second lower limit module. The above-mentioned double limit setting improves the production safety of the converter. For example, even if the first upper limit module fails, the second upper limit module can still keep the skirt in the upper limit position, thereby preventing the skirt from suddenly falling when the converter is tilted, and thus preventing the converter furnace mouth from colliding with the skirt. Even if the first lower limit module fails, the second lower limit module can still keep the skirt in the lower limit position, thereby preventing the skirt from suddenly falling below the lower limit position, and thus preventing the converter furnace mouth from colliding with the skirt. Therefore, the production safety of the converter is improved.

[0031] In some embodiments, a camera is disposed at a position at a first horizontal distance from the converter, and step S101 may include: acquiring an environmental image including the skirt from the camera; and determining a detection position based on the environmental image.

[0032] In some embodiments, determining the detection position based on the environmental image may include: determining the converter mouth area and the hood skirt area of ​​the environmental image; determining the relative distance between the converter mouth area and the hood skirt area based on the converter mouth area and the hood skirt area; and determining the detection position based on the relative distance.

[0033] In some embodiments, a laser emitter is provided at a second horizontal distance from the converter, and the distance between the laser emitter and the ground is a preset vertical distance. The second horizontal distance and the vertical distance are such that when the detection position is the upper limit position, there is no laser emitted by the laser emitter on the skirt in the environmental image. Then, determining the detection position based on the environmental image may include: if there is no laser emitted by the laser emitter on the skirt in the environmental image, determining that the detection position is the upper limit position.

[0034] It should be noted that by setting up a laser transmitter, it is only necessary to determine whether there is a laser on the skirt in the environmental image to determine whether the detection position is the upper limit position, thereby avoiding complex image analysis, improving the convenience of obtaining the detection position, and thus improving the production control efficiency of the converter.

[0035] It should be noted that the laser emitted by the laser emitter can form a fan-shaped surface, and the fan-shaped surface can be kept horizontal with the plane where the furnace mouth is located. In this case, if the laser is irradiated on the skirt, it is also possible to determine whether the skirt is tilted by the parallel relationship between the laser and the bottom of the skirt. Specifically, if the laser is parallel to the bottom of the skirt, it is determined that the skirt is not tilted. If the laser is not parallel to the bottom of the skirt, it is determined that the skirt is tilted. In addition, the laser emitter can be a red laser emitter with an operating temperature of -20℃ to 60℃ and an irradiation range of 20m to 30m. It can fully irradiate the 5-meter diameter of the skirt ground, fully reflect the state of the skirt, and can be intuitively compared once tilt occurs.

[0036] S102: Determine the position deviation of the hood skirt based on the detected position and the set position of the hood skirt.

[0037] In some implementations, step S102 may be: taking the difference between the detected position and the set position of the skirt as the position deviation of the skirt.

[0038] S103: If the position deviation is less than a preset deviation threshold, the converter is controlled to execute a set production action corresponding to the set position.

[0039] It should be noted that a position deviation less than a preset deviation threshold indicates that the skirt is in a set position.

[0040] In some embodiments, the set position may include an upper limit position, and the set production action corresponding to the upper limit position may include tilting. It should be noted that when adding scrap steel before blowing, adding molten iron, tapping steel after smelting, and pouring slag, the skirt needs to be lifted to a high position, such as the upper limit position, before the converter can be tilted to avoid collision between the converter mouth and the skirt. Here, the set position is limited to the upper limit position, which can avoid collision between the converter mouth and the skirt to the greatest extent, thereby greatly improving production safety.

[0041] It should be noted that, in some special cases, in step S103, even if the position deviation is less than the preset deviation threshold, it is not possible to control the converter to perform the set production action corresponding to the set position. For example, the skirt is in the set position but tilted. At this time, controlling the converter to perform the set production action may cause an accident. Therefore, before controlling the converter to perform the set production action corresponding to the set position, the situation that may cause an accident should be judged and an alarm should be issued. The following is a specific explanation:

[0042] In some embodiments, the converter may include a skirt hydraulic system, which may include multiple cylinders and multiple piston rods corresponding to the multiple cylinders, one end of each of the multiple piston rods is connected to the skirt, and the multiple piston rods are used to control the lifting and lowering of the skirt. Before controlling the converter to perform a set production action corresponding to a set position, it may also include: obtaining multiple pressure values ​​of the multiple cylinders; determining the number of abnormal pressure values ​​that are less than a preset pressure lower limit value among the multiple pressure values; if the number of abnormal pressure values ​​is less than a preset number threshold, allowing the converter to be controlled to perform the set production action corresponding to the set position; if the number of abnormal pressure values ​​is equal to or greater than the preset number threshold, not allowing the converter to be controlled to perform the set production action corresponding to the set position, and outputting a first alarm message.

[0043] It should be noted that the pressure value of the oil cylinder is less than the preset pressure lower limit, indicating that the oil cylinder has internal unloading. The number of abnormal pressure values ​​is less than the preset number threshold, indicating that although there is a small amount of internal unloading in the oil cylinder, the hood skirt hydraulic system can normally control the lifting and lowering of the hood skirt, and the inclination of the hood skirt is very small. The number of abnormal pressure values ​​is equal to or greater than the preset number threshold, indicating that there are many cylinders with internal unloading, the hood skirt hydraulic system cannot normally control the lifting and lowering of the hood skirt, and the inclination of the hood skirt may be large. The first alarm information can be information used to prompt that the hood skirt hydraulic system has a fault. Therefore, if the number of abnormal pressure values ​​is equal to or greater than the preset number threshold, the set production action is not allowed to be executed, which avoids the collision between the furnace mouth and the hood skirt when the inclination of the hood skirt is large, thereby improving production safety.

[0044] It should be noted that the preset pressure lower limit may be 80 bar, the multiple oil cylinders may be 4 oil cylinders, the preset quantity threshold may be 1 or 2, etc. In particular, when the preset quantity threshold is 1, if any oil cylinder is unloaded, the converter is not allowed to execute the set production action corresponding to the set position, thus avoiding the possibility of risk and greatly improving the production safety of the converter.

[0045] In some embodiments, if the position deviation is greater than or equal to a preset deviation threshold, a second alarm message is output, wherein the second alarm message may be information for prompting that the skirt is not in a set position.

[0046] It should be noted that due to the particularity of steelmaking, the main function of the active skirt of the converter is to be able to rise and fall to ensure that the atmospheric pressure inside and outside the hood is roughly equal during the converter blowing. This can not only avoid the safety hazard caused by the diffusion of gas in the converter area due to the overflow of high-temperature CO-containing flue gas, but also control the quality of the recovered gas and the amount of recovered steam from being reduced due to excessive air intake. Therefore, in each stage of blowing, the skirt needs to be adjusted to the required gap with the furnace mouth. Before blowing, when adding scrap steel, adding molten iron, and when smelting is completed, the skirt needs to be lifted to a high position and cannot hinder the tilting of the converter. Nowadays, steel mills have higher requirements for the safety of converter smelting and higher reliability. The skirt lifting mechanism can be hydraulically driven. When the skirt is lifted, the 4 oil cylinders can be driven by the skirt hydraulic system to ensure the synchronous lifting and lowering of the skirt. When the skirt is lowered, the 4 oil cylinders are driven to drag the skirt down by switching the hydraulic valve passage. However, due to the heavy deadweight of the skirt, which is usually more than 10 tons, once the synchronous cylinder or the oil cylinder itself has internal unloading, the hydraulic lock fails, etc., the skirt will be reduced to the lower limit with its deadweight, resulting in the skirt slipping. At this time, if the skirt slipping is not discovered in time, once the converter needs to tilt and shake the furnace for smelting, it will cause the furnace mouth and the skirt to interfere and cause a serious accident of scratching the skirt. Therefore, the position of the skirt has always been an important interlock in the converter steelmaking process and is directly involved in steelmaking production. Therefore, the detection of the skirt position occupies a very important position in the converter steelmaking process. All steel mills regard the scraping of the skirt by the furnace mouth as a serious production accident, which also causes great economic losses.

[0047] It should be noted that the skirt located above the converter mouth is in a high temperature environment of about 1600℃. Although there is a protective structure, the high temperature radiation also causes abnormal damage to the detection elements. The necessary actions are provided with the alternating changes in the converter smelting rhythm. When the converter starts to blow, a large amount of high-temperature flue gas flows through the vaporization flue, and the heat load in the vaporization flue increases sharply, and the tube wall temperature and the medium temperature rise sharply. When the smelting reaction reaches the standard gas content, it is necessary to adjust the position of the skirt to ensure the smooth progress of the reaction and to ensure a certain amount of air to enter to ensure the continuous progress of the smelting reaction. When the blowing reaches a certain degree, it is necessary to check the smelting flame by lifting the skirt to judge the smelting temperature and smelting reaction. After the smelting is completed, the skirt is lifted to a high position. After the high position signal appears, the operator is allowed to perform the converter tilting operation to complete the backward steel tapping and forward slag pouring operations. During converter smelting, under the action of charging and oxygen supply intensity, the reaction is violent and splashing is easy to occur, which poses a great safety hazard to personnel around the converter. Therefore, most steel mills take measures to install fire doors in front of and behind the converter to ensure the closedness of the converter space, and only retain a small observation window for observing the smelting reaction. Due to limited vision and insufficient lighting, it will not be discovered in time if the skirt slips. The skirt is water-cooled, and once it is damaged and leaks, it also poses a great safety hazard. Therefore, in view of the special working conditions and operating conditions of converter smelting, how to ensure safe and stable operation, accurately and intuitively feedback the state of the skirt above the furnace mouth to the operator, and avoid serious production accidents such as the furnace mouth scratching the skirt when the converter is tilted, has always been the maintenance focus of safe and stable operation of the converter.

[0048] It should be noted that the magnetic scale in the synchronous distribution cylinder of the skirt hydraulic system is used in conjunction with the travel switch and position encoder to obtain the displacement value of the synchronous cylinder in real time. The lower limit is set with double limits to achieve program protection, ensuring that the cylinder is extended to the predetermined length and the skirt is in a low position; the low-low limit is mainly used to avoid the skirt hitting the furnace mouth caused by the cylinder continuing to move when the lower limit is abnormal. Secondly, after the skirt touches the limit when it rises, it is positioned by comparing with the displacement value to ensure that the four cylinders are in the same compression state after the skirt is lifted to the upper position. A pressure detection point is set in the rod cavity of the cylinder, which is transmitted to the PLC through a 24V signal and further displayed on the centralized control screen. It is used to detect the pressure of the entire cylinder operation process. When the pressure of one of the cylinders is lower than 80bar, an alarm can be given through the main control screen. After the on-site monitoring personnel confirm that it is normal, the converter tilting operation can be performed. Then, for the cylinder pressure detection, when the pressure of more than 2 cylinders is lower than 80bar, the program interlock can be started, and the operator needs to confirm the state of the skirt on site. If it is normal, the main control personnel need to click on the screen to release the interlock before the converter tilting operation can be performed. If the on-site equipment is abnormal, it needs to be maintained and confirmed to be normal. The main control personnel can perform the converter tilting operation after clicking the fault reset. A high-definition, high-temperature fixed camera can be set on the structure opposite the furnace mouth. The camera can view the state of the furnace skirt through the observation window of the front fire-blocking door of the furnace. The camera picture is introduced into the large screen of the control room. The main control operator observes the state of the skirt through the large screen before issuing the converter tilting instruction. The high-definition camera can have a behavior action detection function. According to the intelligent algorithm, the picture analysis is performed at intervals of 10s to record the actual position of the skirt, which can be used as a judgment of the position of the skirt. Secondly, the actual position of the skirt obtained by the intelligent algorithm of the high-definition camera transmits the signal to the PLC, and is displayed to the main control screen through the digital twin, and a virtual image is output to display the displacement value of the skirt. The virtual displacement value is further compared with the displacement value displayed by the hydraulic system distribution cylinder. If it exceeds the rated deviation value (>100mm), tilting operation is prohibited and the machine needs to be stopped for inspection. A mechanical structure safety device is further set up, and a safety pin is inserted during the hydraulic system inspection to avoid the skirt action after the cylinder is depressurized.

[0049] The embodiment of the present invention obtains the detection position of the hood skirt of the converter; determines the position deviation of the hood skirt based on the detection position and the set position of the hood skirt; if the position deviation is less than the preset deviation threshold, controls the converter to execute the set production action corresponding to the set position. The position deviation less than the preset deviation threshold indicates that the hood skirt is in the set position. At this time, the converter can safely execute the set production action, avoiding the overflow of high-temperature CO-containing flue gas and the diffusion of coal gas in the converter area caused by the hood skirt not being in a suitable position, and also avoiding the collision between the converter furnace mouth and the hood skirt caused by the hood skirt not being in a suitable position, thereby reducing the possibility of safety accidents. Therefore, the production safety of the converter is improved at least to a certain extent. In addition, the position of the hood skirt is double-confirmed by the detection position and the set position, which ensures the accuracy of the positioning of the hood skirt, thereby improving the production safety of the converter.

[0050] Based on the same inventive concept, Figure 3 As shown, an embodiment of the present invention provides a production control device 10 for a converter, comprising: a detection unit 110, for obtaining a detection position of a hood skirt of the converter; a deviation determination unit 120, for determining a position deviation of the hood skirt based on the detection position and a set position of the hood skirt; and an execution unit 130, for controlling the converter to execute a set production action corresponding to the set position if the position deviation is less than a preset deviation threshold.

[0051] It can be understood that the converter includes an upper limit member and a lower limit member for limiting the position of the skirt, and the detection unit 110 is specifically used to: if the upper limit signal generated by the upper limit member is detected, determine the detection position to be the upper limit position; if the lower limit signal generated by the lower limit member is detected, determine the detection position to be the lower limit position.

Among them, the preset pressure lower limit value can be 80bar.

[0054] It can be understood that the production control device 10 of the converter further includes: an alarm unit, which is used to output a second alarm message if the position deviation is greater than or equal to a preset deviation threshold.

[0055] It can be understood that the setting position includes an upper limit position, and the setting production action corresponding to the upper limit position includes tilting.
