[0002] In blast furnace metallurgy, the blast furnace charge surface refers to the shape formed by the furnace charge at the throat inside the blast furnace. It reflects the distribution of the charge within the blast furnace and is an important indicator for judging the degree of combustion and the distribution of gas flow. One of the keys to determining the shape of the blast furnace charge surface is the blast furnace charging process, which refers to the process of feeding the metallurgical raw materials (mainly ores and coke) into the blast furnace according to a certain method. Therefore, by monitoring the shape of the blast furnace charge surface and adjusting the charging parameters based on it, the blast furnace charging process can be controlled, thereby maintaining the shape of the blast furnace charge surface in an ideal state. However, the existing methods for monitoring the blast furnace charge surface are not yet perfect and it is difficult to accurately monitor the blast furnace charge surface to adjust the charging parameters. Therefore, how to accurately detect the blast furnace charge surface to improve the accuracy of blast furnace charging control is a technical problem that urgently needs to be solved.

[0006] In some embodiments of this application, based on the foregoing scheme, before adjusting the tilt angle of the blast furnace charging chute to a preset angle, the method further includes: determining the time interval between the current time and the time of the last adjustment of the blast furnace charging parameters; if the time interval is greater than the preset time interval, then performing the step of adjusting the tilt angle of the blast furnace charging chute to the preset angle.

[0007] In some embodiments of this application, based on the foregoing scheme, the denoising process of the initial three-dimensional point cloud image includes: removing interfering point cloud data from the initial three-dimensional point cloud image, wherein the interfering point cloud data includes furnace wall point cloud data, furnace top point cloud data, and furnace dust point cloud data; the cutting process of the target three-dimensional point cloud image includes: cutting the target three-dimensional point cloud image according to a preset cutting direction and a preset cutting angle.

[0008] In some embodiments of this application, based on the foregoing scheme, the material surface data includes at least material surface shape data, the position of the highest point of the material surface, the position of the lowest point of the material surface, the height difference between the highest point and the lowest point of the material surface, and the interval distance between the highest point of the material surface and the center point of the blast furnace. The step of determining the material surface data from the target three-dimensional point cloud map and the two-dimensional cross-sectional view includes: determining the material surface shape data from the target three-dimensional point cloud map; and determining the position of the highest point of the material surface, the position of the lowest point of the material surface, the height difference, and the interval distance from the two-dimensional cross-sectional view.

[0009] In some embodiments of this application, based on the aforementioned scheme, the blast furnace charging parameters include at least the charging chute position, the charging chute angle, and the number of charging rings. Adjusting the blast furnace charging parameters based on the material surface data includes: determining the gas flow direction and gas flow rate in the blast furnace based on the material surface shape data, the high point position, and the low point position; and adjusting the number of charging chute positions, the size of the charging chute angle, and the number of charging rings based on the gas flow direction, the gas flow rate, the height difference, and the interval distance, so that the blast furnace charging is concentrated in the area where the gas flow direction is concentrated and the gas flow rate is large.

[0010] According to a second aspect of the embodiments of this application, a blast furnace charging parameter adjustment system is provided, characterized in that the system is used to perform the method described in any one of the first aspects above, the system comprising: a three-dimensional scanner for scanning the blast furnace charge surface to obtain an initial three-dimensional point cloud image; a data processing device connected to the three-dimensional scanner via a cable for performing noise reduction processing on the initial three-dimensional point cloud image and cutting processing on the target three-dimensional point cloud image; and a cooling device for controlling the temperature of the three-dimensional scanner.

[0015] Based on the technical solution proposed in this application, firstly, after the blast furnace charging is completed, the tilt angle of the charging chute is adjusted to a preset angle. This avoids the charging chute blocking the laser signal emitted by the 3D scanner, thereby improving the accuracy of the initial 3D point cloud map obtained by the 3D scanner from the blast furnace charge surface. Secondly, after adjusting the tilt angle to the preset angle for a first preset time, the 3D scanner is controlled to scan the blast furnace charge surface for a second preset time. The purpose is that by waiting for the first preset time, the dust raised by the charging in the blast furnace can settle down, thus avoiding the dust affecting the scanning of the 3D scanner, thereby improving the accuracy of the initial 3D point cloud map obtained by the 3D scanner. Then, the initial 3D point cloud map is denoised to obtain a target 3D point cloud map. The target 3D point cloud map is then cut to obtain a 2D cross-sectional view, which can more clearly and accurately display the charge surface data of the blast furnace. Based on the charge surface data, the charging parameters are adjusted to improve the accuracy of the charging parameter adjustment.

[0028] To enable those skilled in the art to better understand this application, the blast furnace charging and blast furnace burden surface proposed in this application will be briefly described first.

[0029] In the blast furnace metallurgical process, the blast furnace charge surface refers to the shape formed by the furnace charge at the throat inside the blast furnace. It reflects the distribution of the charge within the blast furnace and is an important indicator for judging the degree of combustion and the distribution of gas flow within the furnace. One of the keys to determining the shape of the blast furnace charge surface lies in the blast furnace charging process, which refers to the process of feeding the metallurgical raw materials (mainly ores and coke) into the blast furnace according to a certain method. Therefore, by monitoring the shape of the blast furnace charge surface and adjusting the charging parameters based on it, the blast furnace charging process can be controlled, thereby maintaining the shape of the blast furnace charge surface in an ideal state. However, in the existing technology, the methods for monitoring the blast furnace charge surface are not yet perfect and it is difficult to accurately monitor the blast furnace charge surface to adjust the charging parameters. Based on this, this application proposes a method and system for adjusting blast furnace charging parameters to improve the accuracy of blast furnace charging control.

[0030] Next, we will combine Figure 1 and Figure 2 The blast furnace charging parameter adjustment system proposed in this application is described in detail.

[0031] See Figure 1 The diagram shows a schematic of a blast furnace charging parameter adjustment system in one embodiment of this application. See also: Figure 2 This shows an enlarged schematic diagram of a 3D scanner and a cooling device in one embodiment of this application, as shown below. Figure 1 and Figure 2 As shown, the blast furnace charging parameter adjustment system may include at least a 3D scanner 101, a data processing device 102, and a cooling device.

[0032] Please refer to Figure 1As shown, the 3D scanner 101 and the data processing device 102 can be connected by a cable. The 3D scanner can be fixed to the top of the blast furnace by a flange, which can, to a certain extent, avoid the high temperature inside the blast furnace from affecting the operation of the 3D scanner 101. In addition, the 3D scanner 101 needs to be kept horizontal during operation to ensure that the initial 3D point cloud map obtained by the 3D scanner 101 is in a horizontal state, thereby improving the accuracy of the initial 3D point cloud map and thus improving the accuracy of blast furnace charging control.

[0033] In this application, the 3D scanner may be a high-speed 3D scanner, specifically a simultaneous localization and mapping laser scanner (i.e., a SLAM 3D laser scanner), and this application does not make any specific limitation in this regard.

[0034] In this application, a high-speed 3D scanner can quickly scan the blast furnace charge surface in a short time and establish an initial 3D point cloud map. This allows for timely subsequent processing of the initial 3D point cloud map and acquisition of the charge surface data, thereby providing guidance for the charge distribution parameters of the blast furnace.

[0035] In this application, the data processing device can specifically be a computer. The initial three-dimensional point cloud map can be denoised using denoising software (such as Geomagic software) to obtain the target three-dimensional point cloud map, and then the target three-dimensional point cloud map can be cut using cutting software to obtain a two-dimensional slope map. This application does not make specific limitations in this regard.

[0036] Please refer to Figure 2 As shown, the cooling device may specifically include a radiator 205 and a cooling pipe, wherein the cooling pipe may include an air inlet 203 and an air outlet 204. The three-dimensional scanner 101 may include at least a laser signal transmitter 201 and a laser signal processor 206. The laser signal transmitter 201 can pass through the furnace wall 202 of the blast furnace and enter the interior of the blast furnace to scan the blast furnace charge surface inside the blast furnace.

[0037] In this application, the cooling device can be used to control the temperature of the 3D scanner to prevent the high temperature inside the blast furnace from affecting the normal operation of the 3D scanner. The radiator is located outside the 3D scanner and can be used to assist the 3D scanner in dissipating heat. The cooling pipe passes through the inside of the 3D scanner and can be used to control the temperature of the 3D scanner. Specifically, compressed air can be introduced into the cooling pipe to reduce the internal temperature of the 3D scanner.

[0038] Next, we will combine Figure 3The method for adjusting the blast furnace charging parameters proposed in this application is described in detail.

[0039] See Figure 3 The diagram illustrates a flowchart of a blast furnace charging parameter adjustment method according to one embodiment of this application. This method can be applied to the system described above, and the blast furnace charging parameter adjustment method may include at least the following steps 310 to 340.

[0040] Step 310: After the blast furnace charging is completed, the tilt angle of the charging chute of the blast furnace is adjusted to a preset angle.

[0041] Step 320: After adjusting the tilt angle to a preset angle for a first preset time, control the 3D scanner to scan the blast furnace material surface within a second preset time to obtain an initial 3D point cloud map.

[0042] Step 330: Denoise the initial three-dimensional point cloud image to obtain the target three-dimensional point cloud image of the blast furnace material surface, and cut the target three-dimensional point cloud image to obtain a two-dimensional cross-sectional view.

[0043] Step 340: Determine the material surface data from the target three-dimensional point cloud map and the two-dimensional cross-sectional map, and adjust the blast furnace charging parameters based on the material surface data.

[0044] In this application, it should be noted that the preset angle can be 15° or 14°. Depending on the actual needs, the preset angle can also be other angles, and this application does not make any specific limitation on this.

[0045] In this application, the first preset duration can be 30 seconds, and the second preset duration can be 10 seconds or 20 seconds. Depending on actual needs, the first preset duration and the second preset duration can also be other durations. This application does not make any specific limitations on this.

[0046] In this application, the completion of blast furnace charging can specifically refer to completing one round of blast furnace charging, that is, adding a layer of ore and a layer of coke into the blast furnace.

[0047] In this application, firstly, after the blast furnace charging is completed, the tilt angle of the charging chute is adjusted to a preset angle. This prevents the charging chute from blocking the laser signal emitted by the 3D scanner, thereby improving the accuracy of the initial 3D point cloud map obtained by the 3D scanner from the blast furnace charge surface. Secondly, after adjusting the tilt angle to the preset angle for a first preset time, the 3D scanner is controlled to scan the blast furnace charge surface for a second preset time. The purpose is that by waiting for the first preset time, the dust raised by the charging in the blast furnace can settle down, thus avoiding the dust affecting the scanning of the 3D scanner and improving the accuracy of the initial 3D point cloud map obtained by the 3D scanner. Then, the initial 3D point cloud map is denoised to obtain a target 3D point cloud map. The target 3D point cloud map is then cut to obtain a 2D cross-sectional view, which can more clearly and accurately display the charge surface data of the blast furnace. Based on the charge surface data, the charging parameters are adjusted to improve the accuracy of the charging parameter adjustment.

[0048] In the blast furnace charging parameter adjustment method proposed in this application, before adjusting the inclination angle of the blast furnace charging chute to a preset angle, the method may also be performed according to the following steps 301 to 302:

[0049] Step 301: Determine the time interval between the current time and the time of the last adjustment of the blast furnace charging parameters.

[0050] Step 302: If the time interval is greater than the preset time interval, then perform the step of adjusting the tilt angle of the charging chute of the blast furnace to the preset angle.

[0051] In this application, the preset time interval can be 1 day or 0.5 days. Depending on actual needs, the preset time interval can also be other time intervals. This application does not make any specific limitation on this.

[0052] In this application, by determining the time interval between the current time after the completion of blast furnace charging and the time of the last adjustment of blast furnace charging parameters, and judging whether the time interval is greater than a preset time interval, the frequency of blast furnace charging parameter adjustment can be controlled by this method. This allows the frequency of blast furnace charging parameter adjustment to better match the adjustment frequency required for actual production, thereby improving the accuracy of blast furnace charging control.

[0053] In step 330 above, the initial three-dimensional point cloud image is subjected to noise reduction processing, which can be specifically performed according to step 331 below:

[0054] Step 331: Remove interfering point cloud data from the initial three-dimensional point cloud map. The interfering point cloud data includes furnace wall point cloud data, furnace top point cloud data, and furnace dust point cloud data.

[0055] In step 330 above, the cutting process of the target 3D point cloud map can be specifically performed according to step 332 below:

[0056] Step 332: Cut the target three-dimensional point cloud map according to the preset cutting direction and preset cutting angle.

[0057] In this application, firstly, by denoising the initial three-dimensional point cloud map, i.e., removing interfering point cloud data from the initial three-dimensional point cloud map, including furnace wall point cloud data, furnace top point cloud data, and furnace dust point cloud data, the accuracy of the target three-dimensional point cloud map in representing the blast furnace burden surface can be improved, and the influence of other point cloud data on the target three-dimensional point cloud map can be reduced, thereby improving the accuracy of the target three-dimensional point cloud map and thus improving the accuracy of blast furnace charging control. Secondly, by cutting the target three-dimensional point cloud map according to a preset cutting direction and preset cutting angle to obtain a two-dimensional cross-sectional view, the burden surface data of the blast furnace burden surface can be displayed more comprehensively, thereby obtaining more specific burden surface data. Based on the burden surface data, the charging parameters of the blast furnace can be adjusted, thereby improving the accuracy of blast furnace charging control.

[0058] In step 340 above, the material surface data includes at least the material surface shape data, the position of the highest point of the material surface, the position of the lowest point of the material surface, the height difference between the highest and lowest points of the material surface, and the distance between the highest point of the material surface and the center point of the blast furnace. The determination of the material surface data from the target three-dimensional point cloud map and the two-dimensional cross-sectional view can be specifically performed according to the following steps 341 to 342:

[0059] Step 341: Determine the material surface shape data from the target three-dimensional point cloud map.

[0060] Step 342: Determine the high point position of the material surface, the low point position of the material surface, the height difference, and the interval distance from the two-dimensional cross-sectional view.

[0061] In this application, please refer to Figure 4 and Figure 5 See Figure 4 This shows a target three-dimensional point cloud map of the blast furnace burden surface in one embodiment of this application; see also Figure 5 This shows a two-dimensional cross-sectional view of the blast furnace burden surface in one embodiment of this application, as follows: Figure 4As shown, the shape data of the blast furnace burden surface can be determined through the target three-dimensional point cloud map. Specifically, the burden surface shape is a ring-shaped funnel, with the outermost ring being a low ring, followed by a high-slope ring, and the center being a large funnel shape. Figure 5 As shown, the two-dimensional cross-sectional view is obtained by cutting the three-dimensional point cloud map of the target in a north-south direction. The two-dimensional cross-sectional view shows that the shape of the material surface is M-shaped. The blast furnace material surface has two peaks. The height difference between the high point and the low point of the two peaks is 0.9795m and 0.8046m, respectively. The specific distances between the high point of the two peaks and the center point of the blast furnace are 2.6813m and 3.1413m, respectively.

[0062] In step 340 above, the blast furnace charging parameters include at least the charging chute position, the charging chute angle, and the number of charging rings. The adjustment of the blast furnace charging parameters based on the material surface data can be specifically performed according to steps 343 to 344 below:

[0063] Step 343: Based on the material surface shape data, the high point position and the low point position of the material surface, determine the gas flow direction and gas flow rate in the blast furnace.

[0064] Step 344: Based on the gas flow direction, gas flow rate, height difference, and interval distance, adjust the number of charging chute positions, the angle of the charging chute, and the number of charging rings to concentrate the blast furnace charging in the area where the gas flow direction is concentrated and the gas flow rate is large.

[0065] In this application, reference continues to be made to Figure 4 and Figure 5 From the target three-dimensional point cloud map and the two-dimensional cross-sectional view, it can be seen that the furnace charge of the blast furnace is concentrated at the midpoint of the blast furnace radius. The gas flow direction at the edge and center of the blast furnace is relatively concentrated and the gas flow rate is large. Therefore, by adjusting the charging chute level, the charging chute angle and the number of charging rings, the subsequent furnace charge can be distributed more at the edge and center of the blast furnace, thereby improving the efficiency of blast furnace smelting.

[0066] In this application, the blast furnace charging parameters are adjusted based on the material surface data obtained from the target three-dimensional point cloud map and two-dimensional cross-sectional view. This allows for timely adjustment of the blast furnace charging according to the shape of the blast furnace material surface, thereby improving the accuracy of blast furnace charging control. Furthermore, by controlling the blast furnace charging, the furnace charge is concentrated in areas with concentrated gas flow direction and large gas flow rate, thereby improving the efficiency of blast furnace smelting.

[0067] Based on the technical solution proposed in this application, firstly, after the blast furnace charging is completed, the tilt angle of the charging chute is adjusted to a preset angle. This avoids the charging chute blocking the laser signal emitted by the 3D scanner, thereby improving the accuracy of the initial 3D point cloud map obtained by the 3D scanner from the blast furnace charge surface. Secondly, after adjusting the tilt angle to the preset angle for a first preset time, the 3D scanner is controlled to scan the blast furnace charge surface for a second preset time. The purpose is that by waiting for the first preset time, the dust raised by the charging in the blast furnace can settle down, thus avoiding the dust affecting the scanning of the 3D scanner, thereby improving the accuracy of the initial 3D point cloud map obtained by the 3D scanner. Then, the initial 3D point cloud map is denoised to obtain a target 3D point cloud map. The target 3D point cloud map is then cut to obtain a 2D cross-sectional view, which can more clearly and accurately display the charge surface data of the blast furnace. Based on the charge surface data, the charging parameters are adjusted to improve the accuracy of the charging parameter adjustment.

[0068] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
