[0048] Example 1

[0049] The embodiment of the present application provides a method for detecting a bottom blowing element of a converter, which can detect blockage of the bottom blowing element of the converter.

[0050] See also Figure 1 The converter includes a bottom blowing element 1, a refractory material 2 and an oxygen lance 3. Figure 2 , the converter also includes a profile scanning probe 4, a controller 5, a bottom blowing element pipeline 6 and a 7-ring seam gas channel. The profile scanning probe 4 is arranged at the bottom of the bottom blowing element, the profile scanning probe 4 is connected to the controller 5, and the 7-ring seam gas channel is arranged close to the bottom blowing element pipeline 6. The converter bottom blowing element detection method can be stored in the controller 5 in the form of a program. In this embodiment, the bottom blowing gas is a colorless, transparent, room temperature gas without solid particles. Combined with the vertical geometric structure of the bottom blowing gas path, a stable optical channel is provided for the profile scanning probe, which meets the continuous and efficient monitoring requirements of the profile scanning probe. The profile scanning probe can be a laser ranging probe. At the same time, the molten metal in the converter is a non-transparent liquid entity medium, which provides a basic condition for the laser reflection effect. And at the outlet of the bottom blowing element, the liquid metal molten pool continues to fluctuate within a certain range under the action of the bottom blowing stream, which causes the bottom blowing element gas path measurement value to continue to fluctuate within a certain range, providing a measurement data reference basis for the detection benchmark of the bottom blowing element during the converter smelting process.

[0051] join Figure 3 The converter bottom blowing element detection method includes steps S301-S306, and each step is described below.

[0052] Step S301, obtaining the converter tonnage and the bottom blowing biomass mode characteristics, and obtaining the bottom blowing element detection benchmark according to the converter tonnage and the bottom blowing biomass mode characteristics.

[0053] In this embodiment, the tonnage and bottom blowing biomass mode characteristics of different converters can be collected to obtain the diameter specifications of the bottom blowing elements of each model of converter, and the diameter threshold of the bottom blowing element when working in the forward direction can be determined. The diameter threshold of the bottom blowing element when working in the forward direction can be used as a bottom blowing element detection benchmark. When it is detected that the current bottom blowing element is smaller than the bottom blowing element detection benchmark, it is determined that the bottom blowing element is blocked.

[0054] In one embodiment, the converter bottom blowing element detection method further includes:

[0055] Determine corresponding bottom blowing element detection benchmarks for different converter tonnages and bottom blowing biomass mode characteristics, so as to form a corresponding relationship between the converter and the bottom blowing element detection benchmarks, and store the corresponding relationship between the converter and the bottom blowing element detection benchmarks;

[0056] The obtaining of the bottom blowing element detection benchmark according to the converter tonnage and the bottom blowing biomass mode characteristics includes:

[0057] Read the current tonnage of the current converter and the characteristics of the bottom-blowing biomass mode;

[0058] The bottom blowing element detection benchmark of the current converter is determined according to the corresponding relationship between the converter and the bottom blowing element detection benchmark.

[0059] Exemplarily, the converter bottom blowing element detection method can set an initialization detection benchmark mode and an operation status detection mode. In the initialization detection benchmark mode, the corresponding bottom blowing element detection benchmarks are intelligently determined for different converter tonnages and bottom blowing biomass mode characteristics to form a correspondence between the converter and the bottom blowing element detection benchmarks, and the correspondence between the converter and the bottom blowing element detection benchmarks is stored and transmitted.

[0060] Step S302, configuring the scanning range and resolution of the profile scanning probe according to the size of the bottom blowing element, and setting the profile scanning probe at the bottom of the bottom blowing element.

[0061] In this embodiment, the contour scanning probe can be a laser ranging probe, which is used to efficiently capture the diameter change of the bottom blowing element. Based on the bottom blowing element detection benchmark, the blockage state of the bottom blowing element is judged to achieve efficient and reliable operation of the bottom blowing element and improve the technical indicators and economic benefits of the converter bottom blowing biomass powder process.

[0062] It should be noted that biomass powder generally only adheres to the pipe wall of the bottom blowing element near the bottom blowing hole. Therefore, the profile scanning probe needs to be set at the tail end of the pipe of the bottom blowing element. It is difficult to accurately measure the blockage situation if it is installed at other positions.

[0063] The preparation work for the profile scanning probe includes: ensuring that the profile scanning probe is in good working condition; calibrating the profile scanning probe to ensure that it measures accurately. Setting scanning parameters for the profile scanning probe includes configuring the scanning range and resolution of the profile scanning probe. In this embodiment, the scanning range and resolution of the profile scanning probe can be adjusted according to the size of the bottom blowing element.

[0064] Step S303, aligning the contour scanning probe with the surface of the bottom blowing element, receiving a start scanning instruction, controlling the contour scanning probe to move or rotate along the surface of the bottom blowing element according to the start scanning instruction, and scanning according to the scanning range and resolution to obtain scanning measurement data.

[0065] In this embodiment, the scanning by the contour scanning probe specifically includes the following steps: aiming the contour scanning probe at the surface of the bottom blowing element, starting the scanning process, the contour scanning probe will move or rotate along the surface of the bottom blowing element, and scan according to the scanning range and resolution to obtain scanning measurement data.

[0066] See also Figure 4 , scanning according to the scanning range and resolution to obtain scanning measurement data, including:

[0067] Step S3031, vertically projecting a laser plane onto the bottom blowing element according to the scanning range and resolution; detecting reflected light reflected from the bottom blowing element;

[0068] Step S3032, generating a bottom blowing element profile according to the reflected light, and determining the bottom blowing element diameter data according to the bottom blowing element profile.

[0069] It should be noted that the contour scanning probe is installed at the tail end of the bottom blowing element pipeline, and the laser plane is projected onto the surface of the object to be measured. Here, the laser plane is projected vertically. When there is an inclination between the surface of the object to be measured and the laser plane, it is difficult to accurately measure the blockage. For example, by vertically projecting the laser plane through the sheet of light of the contour scanning probe, and by using a CMOS camera to receive the changes in the reflected light of the object to be measured, the height, height difference, width and other contour information of the object to be measured can be measured in a non-contact manner. The contour information can be the cross-sectional shape of the bottom blowing element, and the current diameter data of the bottom blowing element can be directly measured based on the cross-sectional shape. When the biomass powder adheres to the wall of the bottom blowing tube, the diameter of the bottom blowing element changes, and the blockage is judged based on the detected current diameter data.

[0070] Step S304, extracting current diameter data of the bottom blowing element from the scanning measurement data, and determining whether the bottom blowing element is blocked according to the bottom blowing element diameter data and the bottom blowing element detection reference.

[0071] In one embodiment, the scanning measurement data includes profile information and diameter data of the bottom blowing element. The profile scanning probe includes a data output interface, through which the scanning measurement data is transmitted to the controller, and the controller extracts the current diameter data of the bottom blowing element from the scanning measurement data. The scanning measurement data is compared with the design specifications to check whether they meet the requirements.

[0072] Step S305: If the current diameter data of the bottom blowing element meets the bottom blowing element detection reference, it is determined that the bottom blowing element is not blocked.

[0073] In this embodiment, if the current diameter data of the bottom blowing element meets the bottom blowing element detection benchmark, it means that the bottom blowing element is currently operating normally, so it can be determined that the bottom blowing element is not blocked.

[0074] Step S306: If the current diameter data of the bottom blowing element does not meet the bottom blowing element detection benchmark, it is determined that the bottom blowing element is blocked.

[0075] In this embodiment, if the current diameter data of the bottom blowing element does not meet the bottom blowing element detection benchmark, it means that the bottom blowing element currently meets the design specifications, and it can be determined that the bottom blowing element is blocked.

[0076] In this embodiment, the scanning measurement data and the detection result of whether the converter is blocked can be saved. If there is a deviation between the scanning measurement data and the detection result, the deviation data can be recorded and adjusted or maintained.

[0077] In this embodiment, scanning measurement data is acquired by a contour scanning probe, and the current diameter value of the bottom blowing element is determined through the scanning measurement data. Whether the bottom blowing element is blocked can be accurately judged based on the current diameter value of the bottom blowing element and the bottom blowing element detection benchmark. The blockage state of the bottom blowing element can be accurately detected within the designed operation cycle of the converter bottom blowing element, thereby ensuring the normal operation of the converter bottom blowing element, effectively improving the technical indicators of the converter bottom blowing biomass powder process, and generating better economic benefits.

[0078] In one embodiment, the bottom blowing element detection reference includes a bottom blowing element forward working diameter reference, and the converter bottom blowing element detection method further includes:

[0079] Determine whether the bottom blowing element is blocked according to the diameter data and the bottom blowing forward working diameter reference;

[0080] If the diameter data is greater than or equal to the bottom blowing forward working diameter reference, it is determined that the bottom blowing element is not blocked;

[0081] If the diameter data is smaller than the bottom blowing forward working diameter reference, it is determined that the bottom blowing element is clogged.

[0082] For example, the converter bottom blowing element detection method can set an initialization detection benchmark mode and an operation detection mode. In the initialization detection benchmark mode, a bottom blowing element forward working diameter benchmark is formed according to the tonnage and bottom blowing mode characteristics of different converters. In the operation detection mode, a contour scanning detection probe built into the bottom of the bottom blowing element is used to obtain the scanning measurement data of the bottom blowing element, and the current diameter data of the bottom blowing element is determined from the contour information of the bottom blowing element in the scanning measurement data. The judgment of whether the bottom blowing element is blocked is completed based on the current diameter data of the bottom blowing element and the forward working diameter benchmark of the bottom blowing element.

[0083] In one embodiment, the converter bottom blowing element detection method further includes:

[0084] Before the start of smelting, the direction of the converter mouth is adjusted to a vertical downward state, and a converter adjustment end signal is generated; a measurement start signal is generated according to the converter adjustment end signal;

[0085] A probe power-on signal is transmitted to the contour scanning probe according to the measurement start signal, so as to control the contour scanning probe to start a working mode.

[0086] It should be noted that, in the operation detection mode, before the start of smelting, the direction of the converter mouth is adjusted to a vertical downward state, and a converter adjustment end signal is generated; a measurement start signal is generated according to the converter adjustment end signal; a probe start signal is transmitted to the profile scanning probe according to the measurement start signal, and the profile scanning probe built into the bottom of the bottom blowing element is controlled to start the working mode; after the profile scanning probe enters the working mode, the scanning measurement data of the bottom blowing element is scanned and the current diameter data of the bottom blowing element is extracted from the profile information of the bottom blowing element in the scanning measurement data, and the judgment of whether the bottom blowing element is blocked is completed according to the current diameter data of the bottom blowing element and the bottom blowing element forward working diameter benchmark. If the analysis result is that the bottom blowing forward working diameter benchmark is met, the operation detection mode is restarted, and the normal operation signal of the bottom blowing element is stored and transmitted.

[0087] In one embodiment, the converter bottom blowing element detection method further includes:

[0088] In the case where the converter is blocked, a blockage alarm signal is generated and the blockage alarm signal is visually displayed.

[0089] In this embodiment, if the analysis result shows that the bottom blowing element forward working diameter standard is not met, the blockage alarm signal is stored and synchronously transmitted, and visually displayed to quickly and accurately alarm.

[0090] For example, during the use of a 100t converter bottom blowing element, the diameter of the bottom blowing element is 11mm, and a profile scanning probe is installed below the outlet of the bottom blowing element, including the following steps: After the profile scanning probe is installed on the bottom blowing element, the initialization detection benchmark mode is selected. In the initialization detection benchmark mode, the bottom blowing element forward working diameter benchmark of the bottom blowing element is generated according to the tonnage of the 100t converter and the characteristics of the bottom blowing mode: the bottom blowing element diameter measurement value ≥ 7mm. The generated bottom blowing element forward working diameter benchmark is stored internally, and the forward benchmark generation signal is synchronized to the controller.

[0091] The controller generates a signal according to the forward reference. Before the 100t converter starts smelting, the operation detection mode is selected. The specific control process is as follows: before the start of this heat smelting, the converter control system adjusts the direction of the 100t converter mouth to a vertical downward state; after the 100t converter mouth is adjusted to a vertical downward state, a converter adjustment end signal is generated and transmitted to the controller. The controller receives the converter adjustment end signal and generates a measurement start signal according to the converter adjustment end signal; according to the measurement start signal, the probe start signal is transmitted to the profile scanning probe to control the profile scanning probe built into the bottom of the bottom blowing element to start the working mode; after the profile scanning probe enters the working mode, it scans and obtains the scanning measurement data of the bottom blowing element, and extracts the current diameter data of the bottom blowing element from the profile information of the bottom blowing element in the scanning measurement data. If the current diameter data of the bottom blowing element is ≥7mm, it returns to restart the operation status detection mode, and transmits the bottom blowing element normal operation signal to the controller; if the current diameter data of the bottom blowing element is ≤7mm, the blocking alarm signal is synchronously transmitted to the controller, and the controller performs the blocking alarm operation.

[0092] After adopting the converter bottom blowing element detection method of this embodiment, the average oxygen supply time of 100t converter smelting is shortened by 14s, the service life of the bottom blowing element is increased by 1138 furnaces, the average oxygen utilization rate is increased by 2.2%, the terminal average carbon-oxygen product is reduced from 0.0030 before the implementation of the technology to below 0.0029, and the terminal average molten steel phosphorus content is stably controlled within 0.033% from 0.035% before the implementation of the technology.

[0093] Furthermore, during the use of the bottom blowing element of the 350t converter, the diameter of the bottom blowing element is 27mm, and a profile scanning probe is installed below the outlet of the bottom blowing element, including the following steps: After the profile scanning probe is installed on the bottom blowing element, the initialization detection benchmark mode is selected. In the initialization detection benchmark mode, the bottom blowing element forward working diameter benchmark of the bottom blowing element is generated according to the tonnage of the 350t converter and the characteristics of the bottom blowing mode: the bottom blowing element diameter measurement value ≥ 14mm. The generated bottom blowing element forward working diameter benchmark is stored internally, and the forward benchmark generation signal is synchronized to the controller.

[0094] The controller generates a signal according to the forward reference. Before the 350t converter starts smelting, the operation detection mode is selected. The specific control process is as follows: before the start of this furnace smelting, the converter control system adjusts the direction of the 100t converter mouth to a vertical downward state; after the direction of the 350t converter mouth is adjusted to a vertical downward state, a converter adjustment end signal is generated and transmitted to the controller. The controller receives the converter adjustment end signal and generates a measurement start signal according to the converter adjustment end signal; according to the measurement start signal, the probe start signal is transmitted to the profile scanning probe to control the profile scanning probe built into the bottom of the bottom blowing element to start the working mode; after the profile scanning probe enters the working mode, it scans and obtains the scanning measurement data of the bottom blowing element, and extracts the current diameter data of the bottom blowing element from the profile information of the bottom blowing element in the scanning measurement data. If the current diameter data of the bottom blowing element is ≥14mm, it returns to restart the operation status detection mode, and transmits the bottom blowing element normal operation signal to the controller; if the current diameter data of the bottom blowing element is ≤14mm, the blocking alarm signal is synchronously transmitted to the controller, and the controller performs the blocking alarm operation.

[0095] After adopting the converter bottom blowing element detection method of this embodiment, the average oxygen supply time of 350t converter smelting is shortened by 11s, the service life of the bottom blowing element is increased by 1213 furnaces, the average oxygen utilization rate is increased by 1.9%, the final average carbon-oxygen product is reduced from 0.0026 before the implementation of the technology to below 0.0025, and the final average molten steel phosphorus content is stably controlled within 0.034% from 0.037% before the implementation of the technology.

[0096] Furthermore, during the use of the bottom blowing element of the 120t converter, the diameter of the bottom blowing element is 25mm, and a profile scanning probe is installed below the outlet of the bottom blowing element, including the following steps: after the profile scanning probe is installed on the bottom blowing element, the initialization detection benchmark mode is selected. In the initialization detection benchmark mode, the bottom blowing element forward working diameter benchmark of the bottom blowing element is generated according to the tonnage of the 120t converter and the characteristics of the bottom blowing mode: the bottom blowing element diameter measurement value ≥ 15mm. The generated bottom blowing element forward working diameter benchmark is stored internally, and the forward benchmark generation signal is synchronized to the controller.

[0097] The controller generates a signal according to the forward reference. Before the 120t converter starts smelting, the operation detection mode is selected. The specific control process is as follows: before the start of this heat smelting, the converter control system adjusts the direction of the 120t converter mouth to a vertical downward state; after the 120t converter mouth is adjusted to a vertical downward state, a converter adjustment end signal is generated and transmitted to the controller. The controller receives the converter adjustment end signal and generates a measurement start signal according to the converter adjustment end signal; according to the measurement start signal, the probe start signal is transmitted to the profile scanning probe to control the profile scanning probe built into the bottom of the bottom blowing element to start the working mode; after the profile scanning probe enters the working mode, it scans and obtains the scanning measurement data of the bottom blowing element, and extracts the current diameter data of the bottom blowing element from the profile information of the bottom blowing element in the scanning measurement data. If the current diameter data of the bottom blowing element is ≥15mm, it returns to restart the operation status detection mode, and transmits the bottom blowing element normal operation signal to the controller; if the current diameter data of the bottom blowing element is ≤15mm, the blocking alarm signal is synchronously transmitted to the controller, and the controller performs the blocking alarm operation.

[0098] After adopting the converter bottom blowing element detection method of this embodiment, the average oxygen supply time of 120t converter smelting is shortened by 14s, the service life of the bottom blowing element is increased by 1189 furnaces, the average oxygen utilization rate is increased by 2.1%, the terminal average carbon-oxygen product is reduced from 0.0026 before the implementation of the technology to below 0.0024, and the terminal average molten steel phosphorus content is stably controlled within 0.033% from 0.039% before the implementation of the technology.
