Description

Technical Field

[0001] This invention relates to the field of metallurgical technology, and in particular to a slag control method, system, equipment and medium based on image recognition. Background Technology

[0002] During VD (Vacuum Degassing) refining, due to the poor surface fluidity and increased bubble-holding capacity of the steel slag, the volume expansion becomes increasingly violent as the vacuum level increases and argon gas is introduced. This makes it difficult for bubbles to move freely through the slag and escape. When the amount of gas entering the slag layer exceeds the amount exiting, bubbles accumulate in the slag layer. This manifests as the steel slag churning and rising continuously along the ladle wall. If slag pressing is not performed, the steel slag will overflow the ladle cover and damage the relevant vacuum equipment. Summary of the Invention

[0045] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0046] It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. Unless otherwise specified, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0047] This application provides an image recognition-based slag control method, system, device, and medium, which at least partially solves the technical problem in the prior art where steel slag overflows from the ladle cover and damages related vacuum equipment. It achieves the technical effect of adjusting the overflow rate of gas from the slag and the exhaust rate to a balance point, thereby preventing steel slag from overflowing from the ladle cover.

[0048] The technical solution of this application embodiment is to solve the above-mentioned technical problems, and the general idea is as follows:

[0049] Image recognition technology is used to capture slag-turning features. By calculating the slag-rising rate, the risk level of slag-turning at the onset of slag-rising is quantified. During the slag-pressing circulation stage, based on parameters such as the slag-rising rate, the peak slag-rising and peak slag-pressing fall are calculated, optimizing the pressure relief valve opening mechanism during the slag-rising and slag-pressing fall stages. When the vacuum level meets the requirements and molten steel is exposed, the slag-pressing control ends. By opening the pressure relief valve, the rate of vacuum decrease in the furnace is reduced, slowing down the rate of gas overflow from the slag until the overflow rate and exhaust rate reach an equilibrium point. This achieves the effect of preventing slag from overflowing from the ladle cover by controlling the pressure relief valve.

[0050] In the embodiments of this application, the following are provided: Figure 1 and Figure 2 The image recognition-based slag control method shown includes steps S101 to S104:

[0051] Step S101: Obtain slag turning features using image recognition;

[0052] The feature extraction process employs image recognition technology, primarily identifying features such as slag height, molten steel exposure, and ladle edge appearance for each second of the image. The initial slag height is based on the relative height when the initial molten steel level is 0. Slag control is calculated every 5 seconds, and the processed slag height is the average of the slag heights within the previous 5 seconds.

[0053] Step S102: Quantify the risk level of slag overturning based on the slag-raising rate;

[0054] In this step, the risk level of slag overturning at the moment of slag removal is quantified. When the slag removal height is greater than 500mm, the risk level of slag overturning and the number of pressure relief valves to be opened are initialized based on the slag removal rate.

[0055] Step S103: Establish a pressure relief valve opening and closing mechanism based on the above-mentioned slag spill risk level.

[0056] Please refer to Figure 4 The specific implementation method is as follows:

[0057] S301: When the height of the slag rising in the above-mentioned slag-turning features exceeds a preset threshold, calculate the slag-turning rise rate;

[0058] When the slag height exceeds 500mm, calculations are performed, firstly by determining the rising rate v. up The calculation is performed using the following formula:

[0059] v up =(d H1 -d H0 ) / dt

[0060] Where, d H0d represents the initial slag removal height. H1 The height of the slag within time t;

[0061] S302: Set risk levels according to the above-mentioned rate of increase.

[0062] Therefore, the risk level R is calculated using the following formula:

[0063] R = v up / 3

[0064] S303: Preset risk warning ranges according to different risk levels mentioned above, and control the corresponding pressure relief valve to perform the opening operation according to the risk warning range that the current risk level value meets.

[0065] The judgment criteria for establishing this mechanism are as follows:

[0066] When the risk level R is in the range [0,5), the number of pressure relief valves opened is 0.

[0067] When the risk level R is in the range [5,7), the number of pressure relief valves opened is 1.

[0068] When the risk level R is in the range [7,9), the number of pressure relief valves opened is 2.

[0069] When the risk level R is in the range [9,10], the number of pressure relief valves opened is 3.

[0070] Step S104: The pressure relief valve is automatically adjusted according to the above opening and closing mechanism until the preset slag-turning state is identified.

[0071] It should be noted that the pressure relief valve is controlled using a preset mechanism through data communication between the slag control system and the primary basic automation control system. This enables automatic control of the pressure relief valve, thereby shortening the vacuum pre-evacuation time and improving VD refining efficiency. It also completes the automatic control of slag-turning characteristics capture, quantifies the slag-turning risk level at the start of slag removal, and coordinates with the pressure relief valve's opening and closing mechanism.

[0072] Furthermore, such as Figure 3 As shown; after establishing the pressure relief valve opening and closing mechanism based on the aforementioned slag spill risk level, the above method further includes:

[0073] Step S201: Determine the slag rising stage and the slag falling stage based on the change value of the slag rising rate within a preset time period;

[0074] Step S202: Calculate the number of pressure relief valves that need to be opened; and update the opening and closing mechanism as described above.

[0075] It should be noted that the calculations related to the peak values ​​of slag rise and slag fall are intended to optimize the preset mechanism, thereby achieving more precise adjustment of the pressure relief valve. Essentially, it calculates the number of pressure relief valves to be opened based on the change in the slag rise rate.

[0076] During the slag-raising phase, the change in slag-raising rate is d. vup =(v up1 -v up0 The calculation of ) / dt here is essentially equivalent to calculating its acceleration, which can more intuitively show the rising and falling stages of slag, and thus optimize the original mechanism. The optimization is as follows:

[0077] (1) If the current stage is the slag rise phase:

[0078] When d vup Within the range [0,5), the number of pressure relief valves opened remains unchanged;

[0079] When d vup Within [5,10), the number of pressure relief valves opened increases by one;

[0080] When d vup Within [10,∞], the number of pressure relief valves opened increases by two.

[0081] (2) If the current stage is the slag falling back: (It can also be referenced to the change value of slag lifting rate d) vup =(v up1 -v up0 The difference between this and the rising slag stage is that the resulting value is negative.

[0082] When d vup Less than 0, and |d vup If the number is less than 5, the number of pressure relief valves opened remains unchanged;

[0083] When d vup Less than 0, and |d vup If the value is within [5,10), the number of pressure relief valves opened decreases by one;

[0084] When d vup Less than 0, and |d vup If the value is in the range [10,∞], then the number of pressure relief valves opened is reduced by two.

[0085] Furthermore, the steps for determining the slag-raising and slag-falling stages mentioned above also include:

[0086] Based on the edge-wrapping characteristics in the above-mentioned slag-turning features, and the positive or negative value of the slag-rising rate change value, the slag-rising stage and the slag-pressing and falling stage are determined.

[0087] The opening and closing of the aforementioned pressure relief valves are controlled according to the preset pressure relief valve opening priority.

[0088] It should be noted that the calculation of the slag rising and pressing falling phases is equivalent to calculating the peak values ​​of the slag rising and pressing falling phases. Essentially, it involves calculating the peak and trough states based on the rate of change of the slag rising speed, with the aim of preparing for optimizing the pressure relief valve opening mechanism. The implementation method is as follows:

[0089] Set a reference value, namely the current state V. c =0;

[0090] The calculation of the rising stability signal is as follows: when the height of the slag removal from the ladle edge is greater than 50mm, the slag removal speed is within the range of (0,5), and the duration is greater than 10s, it is determined that the ladle edge has not been reached. When the height of the slag removal from the ladle edge is less than or equal to 50mm and the slag is exposed above the ladle edge, it is determined that the ladle edge has been reached and the top of the ladle is exposed above the ladle edge.

[0091] Among them, a clear pullback signal is defined as: the slag-raising rate is less than 0, and the absolute value of the slag-raising rate is greater than 5. If either of the two conditions for a stable upward signal is met, or if there is a clear pullback signal, let V... c =1.

[0092] The calculation of the stabilization signal is as follows: when the height of the slag riser from the edge of the container is greater than 50mm, the slag riser speed is less than 0, the absolute value of the slag riser speed is less than 5, and the duration is greater than 10s, it is determined that the top of the container edge has not been reached. When the height of the slag riser from the edge of the container is less than 50mm, the slag riser speed is less than 0, the absolute value of the slag riser speed is less than 5, and the duration is greater than 20s, it is determined that the slag riser is near the edge of the container. If one of the conditions for the stabilization signal is met, or if there is a significant upward signal, then V is set... c =0.

[0093] Among them, a significant rate of increase signal is: slag-raising speed greater than 5.

[0094] It should also be noted that the 1-second image recognition technology design is based on the image recognition capability and calculation deviation range. The 5-second slag pressing control system design is based on parameters designed to withstand large fluctuations in image recognition parameters and the stability of slag pressing data. The initial slag lifting height is the relative height predicted by image recognition calculation based on the initial molten steel level being 0. The processed slag lifting height is the average of the slag lifting heights of the previous 5 seconds. The slag lifting distance from the ladle edge is equal to the difference between the absolute clearance height and the processed slag lifting height. This gives the invention the characteristics of strong adaptability, accurate control, and high automation, facilitating the implementation of automatic VD slag pressing control.

[0095] Additionally, the priority setting is as follows:

[0096] During the slag lifting and rising phase, the priority for opening the pressure relief valves by one and two is as follows: furnace cover valve > elbow valve N > elbow valve B;

[0097] During the slag sludge fall-off stage, the priority for opening the number of pressure relief valves reduced by one and two is as follows: bend valve B > bend valve N > furnace cover valve.

[0098] Furthermore, the steps described above, up to identifying the preset slag-turning state, also include:

[0099] When the molten steel is detected to be emerging from the top of the liquid surface and in a stable state based on image recognition technology within the preset vacuum range, the slag pressing control ends.

[0100] It should be noted that this invention aims to prevent slag from overflowing the ladle cover. During the slag turning process, the slag rises, resulting in the slag being on top and the molten steel below. At this point, based on image recognition, the stable state is such that, after the aforementioned series of adjustments, the molten steel is visible from the top of the liquid surface, i.e., above the slag. Furthermore, at this time, the molten steel is yellowish-white, distinct from the reddish slag, allowing for direct image recognition using color spectroscopy, thus marking the end of the slag pressing control.

[0101] Furthermore, prior to the acquisition of slag-turning features using image recognition, the method also includes:

[0102] Once the ladle reaches the preset processing position and the sensor detects that the vacuum tank has descended, the data collected for the preset clearance height is initialized. The purpose is to initialize the data before the slag-turning process, thereby improving the convenience of subsequent calculations.

[0103] Furthermore, the steps for automatically adjusting the pressure relief valve according to the aforementioned opening and closing mechanism also include:

[0104] The aforementioned opening and closing mechanism automatically controls any of the aforementioned pressure relief valves through data communication between the slag pressure control system and the primary basic automation control system.

[0105] Based on the above method, this embodiment uses the following example: initial vacuum temperature: 1623℃; absolute clearance height: 900mm; target vacuum end temperature: 1575℃; molten steel weight: 213 tons.

[0106] Step 1: After the ladle reaches the bottom processing position and the vacuum tank descends, the initial clearance height is recorded as 900mm.

[0107] Step 2: Slag-raising feature capture. As the vacuum level gradually decreases, the molten steel surface in the ladle begins to fluctuate. At a vacuum level of 8 kPa, the molten steel surface begins to rise along the ladle wall. Using image recognition technology, the slag-raising height, molten steel appearance, and ladle edge appearance are identified every second. The slag-raising height exhibits a sawtooth-like trend. The processed slag-raising height is the average of the slag-raising heights in the previous 5 seconds; the slag-raising rate v... up =(d H1 -dH0 ) / dt; the rate of change of slag-raising speed d vup =(v up1 -v up0 ) / dt.

[0108] Step 3: When the slag height exceeds 500mm, the peak state V c =0;

[0109] Based on the image recognition of the slag height, the slag rise rate v is calculated. up =18mm / s;

[0110] Based on the rate of slag rise, the risk level is calculated to be R = 6;

[0111] According to the risk warning standard: if the risk level is in the range of [5,7), open 1 pressure relief valve; according to the pressure relief valve opening priority standard: open the furnace cover pressure relief valve.

[0112] Through data communication between the slag pressing control system and the primary basic automation control system, the signal for opening the furnace cover pressure relief valve is sent to the primary basic automation control system for automatic execution.

[0113] Step 4: Peak State V c =0, calculate the rate of change d of the slag-raising speed. vup The current stage is determined to be the slag-raising phase. The pressure relief valve opening mechanism is calculated as follows:

[0114] When d vup Within the range [0,5), the number of pressure relief valves opened remains unchanged;

[0115] When d vup Within [5,10), the number of pressure relief valves opened increases by one;

[0116] When d vup Within [10,∞], the number of pressure relief valves opened increases by two.

[0117] Step 5: Peak State V c =0, the image identifies two signals: slag reaching the top of the ladle and then protruding from the ladle edge, which are determined to be the peak stage of slag formation V. c The change from 0 to 1 marks the beginning of a stable upward trend in slag removal, which is the end of the upward phase of slag removal.

[0118] The signal for reaching the top of the ladle is: the distance between the slag removal point and the edge of the ladle is less than or equal to 50mm.

[0119] Exposed edge signal;

[0120] Step 6: Value State V c =1, calculate the rate of change d of the slag-raising speed. vupIf the value is less than 0, it is determined that the current stage is the slag retraction phase. Calculate the pressure relief valve opening mechanism:

[0121] When d vup Less than 0, and |d vup If the number is less than 5, the number of pressure relief valves opened remains unchanged;

[0122] When d vup Less than 0, and |d vup If the value is within [5,10), the number of pressure relief valves opened decreases by one;

[0123] When d vup Less than 0, and |d vup If the value is in the range [10,∞], then the number of pressure relief valves opened is reduced by two.

[0124] Step 7: Current peak state V c =1, the height of the slag removal from the edge of the baffle is 40mm, the slag removal speed is less than 0 and the absolute value of the slag removal speed is less than 5, and the duration is 25s, which is judged as the trough state of slag pressing. c The change from 1 to 0 marks the end of the slag retraction stage;

[0125] Step 8: When the vacuum degree is less than 1 kPa, based on image recognition technology, molten steel can be seen emerging from the top of the liquid surface, and the slag turning presents a uniform and stable state, thus ending the slag pressing control.

Calculate the number of pressure relief valves that need to be opened; and update the opening and closing mechanism accordingly. Based on the edge-wrapping characteristics in the slag-turning features and the sign of the slag-rising rate change value, the slag-rising stage and the slag-pressing and falling stage are determined. The opening and closing of the pressure relief valve is controlled according to the preset pressure relief valve opening priority; During the slag lifting and rising phase, the priority for opening the pressure relief valves by one and two is as follows: furnace cover valve > elbow valve N > elbow valve B; During the slag fall-off stage, the priority of opening the pressure relief valves by one and two is as follows: bend valve B > bend valve N > furnace cover valve; the execution module is used to control the pressure relief valves to automatically adjust according to the opening and closing mechanism until the preset slag turning state is identified.
