Description

Technical Field

[0001] The present application relates to the field of control technology in the steelmaking process of the metallurgical industry, and in particular to a method for accurately collecting time in the process of adding molten iron to a converter and related equipment. Background Art

[0002] At present, in the steelmaking process of the metallurgical industry, after desulfurization, molten iron is usually hoisted to the converter by a crane, and then the crane cooperates with the tilting of the converter to pour the molten iron into the converter for smelting. The operation time of adding molten iron is crucial to the entire production process, involving production safety, operation efficiency and environmental protection control.

[0003] However, during the coordinated operation of the overhead crane and the converter, the recording of the time of adding molten iron is usually done manually. The operator observes the outflow and stop of molten iron based on experience, and records the start and end time of adding molten iron. Since the existing method of recording the time of adding molten iron mainly relies on manual recording triggers, there are inaccurate records, time delays and personnel negligence. Sometimes, the operator forgets to record due to busyness, and the time error is large during the subsequent supplementary recording, resulting in unstable process control. Although simple automatic monitoring devices have been introduced in some systems, most of them are limited to the position recording of the overhead crane, and fail to accurately combine various data such as the weight of the overhead crane, image recognition and the angle change of the converter for comprehensive analysis. At present, there is no appropriate method to solve the above problems. Therefore, it is necessary to propose a method for accurate time collection in the process of adding molten iron to the converter to at least solve some of the above problems.

[0043] See also Figure 1 , which is a schematic diagram of a process of accurately collecting time in a converter adding molten iron process provided by an embodiment of the present application, and may specifically include:

[0044] S110, obtaining weight information of the iron ladle in the overhead travelling crane;

[0045] Exemplarily, the weight information of the iron ladle in the overhead crane is obtained. This weight information is real-time weight information, which can ensure the safety of the overhead crane during the lifting process. If the lifting is overweight, serious accidents such as damage to the mechanical structure of the overhead crane and breakage of the wire rope may occur. By obtaining the weight information in real time, the operator can take measures before overweight to avoid dangerous situations. For iron ladle of different weights, the operating parameters of the overhead crane (such as lifting speed, running speed, etc.) also need to be adjusted accordingly. Understanding the weight information helps the operator to reasonably set the parameters of the overhead crane to ensure the smoothness and safety of the lifting process.

[0046] S120, in response to a preset condition, determining whether the weight information is reduced;

[0047] Exemplarily, different overhead cranes lift the iron ladle containing molten iron from the desulfurization, and the crane moves to the designated converter. The overhead crane operator is responsible for operating the overhead crane to move the iron ladle containing molten iron to the converter iron filling port. In response to the preset conditions, it is proved that the overhead crane has the iron filling conditions at this time, and then it is determined whether the weight information is reduced. S130. In the case where the weight information is reduced, the start time of adding molten iron is obtained according to the current time;

[0048] For example, when the weight information of the iron ladle is monitored to decrease, it means that the molten iron begins to flow out of the iron ladle. This is because the overhead crane moves the iron ladle to the iron-adding port of the converter and starts the iron-adding operation, and the molten iron flows from the iron ladle into the converter, causing the weight of the iron ladle to decrease. When it is detected that the weight of the iron ladle begins to decrease, the system automatically obtains the current time and marks this time as the start time of adding molten iron. This time can be very precise, for example, accurate to seconds or even smaller time units, so that the subsequent iron-adding process can be analyzed and monitored more accurately. Determining the start time of adding molten iron is very important for monitoring and management of the steel production process. It can help production personnel understand the specific time point of the iron-adding operation so as to better arrange subsequent production steps. At the same time, this time information can also be used for recording and analyzing production data. For example, the duration of the iron-adding process can be counted, the flow rate of the molten iron can be calculated, etc., so as to optimize the production process and improve production efficiency and quality.

[0049] S140. When the weight information is 0, the end time of adding molten iron is obtained according to the current time.

[0050] For example, when the weight information of the iron ladle becomes 0, it means that all the molten iron in the iron ladle has been poured out. This is because during the iron addition process, the molten iron flows from the iron ladle into the converter. As the molten iron continues to flow out, the weight of the iron ladle will gradually decrease. When the molten iron in the iron ladle is completely emptied, the weight will become 0. The system continuously monitors the weight information of the iron ladle. When it is detected that the weight of the iron ladle becomes 0, the system will immediately obtain the current time. This time is marked as the end time of adding molten iron, which is used to accurately record the completion time of the iron addition operation. Determining the end time of adding molten iron is very important for process control and data analysis of steel production. It can help production personnel understand the duration of the iron addition process so as to reasonably arrange subsequent production processes. This time information can also be combined with the start time of adding molten iron to calculate the total duration of adding iron, providing data support for optimizing the production process and improving production efficiency. At the same time, recording the end time of adding molten iron also helps to trace and control the production process and ensure that every production link can proceed as planned.

[0051] In summary, the precise time acquisition method during the process of adding molten iron to the converter proposed in the embodiment of the present application obtains the weight information of the iron ladle in the overhead crane; in response to a preset condition, determines whether the weight information is reduced; when the weight information is reduced, obtains the start time of adding molten iron according to the current time; when the weight information is 0, obtains the end time of adding molten iron according to the current time. The start and end times of adding molten iron can be automatically collected to avoid errors in human recording. The real-time transmission of the position information of the overhead crane and the weight information of the iron ladle is achieved through the communication system, which greatly improves the operating efficiency.

[0052] In some examples, in response to a preset condition, the step of determining whether the weight information is reduced includes:

[0053] Get the location information of the overhead crane;

[0054] When the position information reaches a preset position, it is determined whether the weight information decreases.

[0055] For example, an overhead crane is responsible for carrying heavy objects such as iron ladles during steel production. The position information of the overhead crane can accurately reflect the specific position coordinates of the overhead crane in the production workshop. Once the position information of the overhead crane reaches the preset position, the system will start to check the weight information of the iron ladle. By comparing with the previously recorded weight data, it is determined whether the current weight of the iron ladle is less than before. If the weight decreases, it may mean that molten iron begins to flow out of the iron ladle and the iron addition operation is carried out; if the weight does not change or increases, it may mean that the iron addition operation has not yet started or an abnormal situation has occurred. The judgment of the iron ladle weight information is triggered by monitoring the position information of the overhead crane to determine whether the iron addition operation has started. This can achieve precise control and monitoring of the production process and improve production efficiency and safety.

[0056] In some examples, the step of obtaining the position information of the overhead travelling vehicle includes:

[0057] Obtain the crane's trolley position information based on the Gray busbar;

[0058] Obtain the position information of the overhead crane in real time based on the laser rangefinder;

[0059] The position information of the overhead crane is obtained by performing calculations based on the position information of the large vehicle and the position information of the small vehicle.

[0060] For example, Gray busbar is a device that uses the principle of electromagnetic induction to achieve position detection. It is usually installed on the overhead crane sliding wire bracket to record the position of the overhead crane trolley in real time. The trolley of the overhead crane refers to the part of the overhead crane that moves on the horizontal track of the workshop as a whole. When the trolley moves on the track, the Gray busbar can determine the position coordinates of the trolley on the track in real time by sensing a specific signal source on the overhead crane (such as an induction coil, etc.). This position information can be an absolute position (such as a specific length from the starting point of the track) or a relative position (such as a position relative to a specific reference point). A laser rangefinder is an instrument that uses a laser beam to measure distance. It is usually installed on the trolley of the overhead crane or fixed at a certain position in the workshop and aimed at the trolley for measurement. The laser rangefinder emits a laser beam and receives the reflected laser signal, calculates the distance to the trolley based on the propagation time and speed of the laser, and thus determines the position of the trolley on the overhead crane beam in real time. The position information of the trolley on the track and the position information of the trolley on the overhead crane beam are comprehensively calculated. For example, if the trolley is at the X coordinate on the track and the trolley is at the Y coordinate on the overhead crane beam, the overall position of the overhead crane can be expressed as (X, Y). Through this calculation, the specific position of the overhead crane in the three-dimensional space of the workshop can be accurately determined.

[0061] In some examples, in response to a preset condition, the step of determining whether the weight information is reduced further includes:

[0062] Get real-time iron clad images;

[0063] Analyzing and processing the iron bag image according to a pattern recognition algorithm to obtain the iron bag number;

[0064] Obtaining an iron bag characteristic image according to the iron bag number;

[0065] Calculating the iron ladle feature image according to an edge detection algorithm to obtain the iron ladle edge feature;

[0066] Calculating the position information of the iron ladle according to the edge features of the iron ladle;

[0067] When the iron ladle position information reaches a preset position, it is determined whether the weight information decreases.

[0068] Exemplarily, a real-time image of the current iron bag is obtained by installing a camera or image acquisition device at a specific location. This image contains information such as the appearance, shape, and position of the iron bag. The collected iron bag image is analyzed and processed using computer vision and image processing technology. For example, specific identification, numbering, and other information on the iron bag can be identified through methods such as image feature extraction and template matching, thereby determining the iron bag package number. Each iron bag has a unique package number, which can be associated with specific iron bag information, such as the capacity of the iron bag, historical usage records, etc., which helps to accurately track and manage the iron bag.

[0069] According to the iron bag number, the iron bag feature image corresponding to the bag number is retrieved from the database or storage system. This feature image may be a pre-stored standard image, or a representative image generated based on historical data. The iron bag feature image is processed using edge detection algorithms in image processing, such as the Sobel operator, Canny edge detection, etc. These algorithms can detect the edge contours of objects in the image, thereby extracting the edge features of the iron bag. The edge features of the iron bag can provide important information about the shape, size, and position of the iron bag. For example, the center position, boundary range, etc. of the iron bag can be determined by edge features.

[0070] Using edge features and other relevant image information, mathematical calculations or geometric analysis methods are used to determine the specific location information of the iron package in space. This may include the coordinate position, height, angle, etc. of the iron package. Through precise analysis and calculation of the iron package feature image, more accurate iron package location information can be obtained, providing a reliable basis for subsequent judgment and operation.

[0071] Compare the calculated iron ladle position information with the preset position. If the iron ladle position information matches the preset position, it means that the iron ladle may have reached the position for the iron exchange operation. After determining that the iron ladle position has reached the preset position, the system starts to check whether the weight information of the iron ladle has decreased. By comparing with the previously recorded weight data, it is determined whether the current weight of the iron ladle has decreased. If the weight has decreased, it may mean that the iron exchange operation has begun; if the weight has not changed or increased, it may mean that the iron exchange operation has not yet started or an abnormal situation has occurred.

[0072] In some examples, the step of determining whether the weight information is reduced in response to a preset condition includes:

[0073] The position information and the weight information are transmitted to a ground server based on a communication system to achieve remote control of the overhead crane.

[0074] Exemplarily, the position information of the overhead crane and the weight information of the iron ladle are sent to the ground server through the communication system. The position information is very important for the ground operators, who can know the specific position of the overhead crane in the workshop in real time for scheduling and safety monitoring. The ground operators can remotely control the overhead crane through a control terminal (such as a computer, tablet computer, etc.) connected to the ground server. Based on the received position information and weight information, the operator can issue instructions to control the movement, lifting, lowering and other actions of the overhead crane. For example, when it is found that the position of the overhead crane is inaccurate, the driving direction and speed of the overhead crane can be adjusted remotely; when the weight information shows that the molten iron in the iron ladle is about to be emptied, the overhead crane can be controlled in time to stop the iron exchange operation.

[0075] In some examples, the steps after obtaining the weight information of the iron ladle in the overhead travelling vehicle include:

[0076] Based on the high-definition camera at the converter mouth, it monitors in real time whether there is molten iron flowing into the converter mouth or flowing out of the ladle mouth.

[0077] For example, a high-definition camera is installed at the converter mouth in order to clearly capture the situation of the converter mouth and the iron ladle during the iron addition process. These cameras usually have high resolution, high frame rate and good low-light performance, so as to accurately monitor the flow of molten iron in a complex industrial environment. The high-definition camera at the converter mouth continuously captures images and transmits the image data to the monitoring system in real time for analysis. This ensures that the operator can timely understand the changes in the status of the converter mouth and the iron ladle. When the sky car lifts the iron ladle above the converter for iron addition operation, it is necessary to monitor whether there is molten iron flowing into the converter mouth. If there is molten iron flowing in, it means that the iron addition operation is proceeding normally. This can be judged by observing the color change of the furnace mouth, the flow trajectory of the molten iron and other characteristics. For example, when molten iron flows into the converter, the temperature around the furnace mouth will increase and the color will become brighter. At the same time, it is also necessary to monitor whether there is molten iron flowing out of the ladle mouth. If there is molten iron flowing out of the ladle mouth, it means that the ladle is damaged or leaking. This is very dangerous because the leakage of molten iron may cause serious accidents such as fire and explosion. By monitoring the opening of the iron ladle, problems can be discovered in time and corresponding measures can be taken, such as stopping the iron adding operation, replacing the iron ladle, etc.

[0078] In some examples, the step of obtaining the weight information of the iron ladle in the overhead travelling crane includes:

[0079] Based on the pressure sensor, the pressure signal of the iron ladle is obtained.

[0080] The pressure signal is converted into the weight information based on a weighing module.

[0081] For example, a pin-type pressure sensor is installed on the drum shaft of the overhead crane, or a tension pressure sensor is installed on the fixed end of the wire rope. The weighing module is usually installed in the control room of the overhead crane or in a nearby electrical cabinet so that the operator can monitor and process the data, and the pressure signal is transmitted to the weighing module for processing to obtain the weight information of the iron ladle. This method can achieve high-precision weight measurement and can adapt to different types of overhead cranes and iron ladle.

[0082] like Figure 2 As shown, this application proposes a precise time acquisition system for the process of adding molten iron to a converter, and the system includes:

[0083] Overhead crane weighing module 21 and time acquisition module 22;

[0084] The overhead crane weighing module 21 is configured to: obtain the weight information of the iron ladle in the overhead crane; in response to a preset condition, determine whether the weight information is reduced;
