[0038] During submerged arc furnace production, electrode paste is calcined at high temperatures, carbonizing it into solid electrodes. This electrode is constantly consumed during operation, necessitating timely addition of electrode paste to prevent potential electrode accidents. Therefore, electrode paste height has always been a crucial production control parameter. During normal production, large amounts of dust and small amounts of harmful gases, such as CO, are constantly generated within the electrode shell. Currently, electrode paste measurement is mostly done manually, which can lead to measurement errors and can also cause significant harm to the human body.

[0039] Manual measurement typically involves manually lowering a rope with a heavy hammer attached into the electrode shell. Once the heavy hammer is lowered onto the paste in the electrode shell, the length of the rope is recorded as the length of the paste. When adding paste, the paste is also manually hoisted into the electrode shell using an electric hoist. During normal production, large amounts of dust and small amounts of harmful gases such as CO are continuously generated within the electrode shell. Operators must perform paste measurement and addition tasks in this hazardous environment, which can be extremely harmful to the human body over the long term. Furthermore, this method relies entirely on manual control and measurement based on the naked eye or experience, lacking a calibration algorithm, resulting in low precision and efficiency.

[0040] In view of this, the present application provides an operation and control system for electrode paste for an electric arc furnace, which can automatically measure the height of the electrode paste column, replace manual operation, improve measurement accuracy and efficiency, and reduce safety risks.

[0041] Figure 1A and Figure 1B A schematic diagram of an operation control system for electrode paste for a submerged arc furnace according to an embodiment of the present application is shown.

[0042] like Figure 1A As shown, the operation control system 100 for electrode paste for an electric arc furnace provided in the embodiment of the present application includes: an intelligent overhead crane system 110, a weighing system 120, a lifting length encoder 130, and a paste measurement control module (not shown in the figure).

[0043] The intelligent overhead crane system 110 is provided with a traction device 111 and a counterweight device 112 connected to one end of the traction device 111, and is configured to control the lifting and lowering of the traction device based on the received control instructions, so as to lift the counterweight device connected to one end of the traction device to the surface of the electrode paste column in the electrode shell; the weighing system 120 is configured to measure the weight change data of the counterweight device 112 during the process of lifting the counterweight device to the surface of the electrode paste column; the lifting length encoder 130 is configured to record the first lifting length data of the traction device 111; the paste measurement control module is configured to send control instructions to the intelligent overhead crane system 110, and measure the height data of the electrode paste column based on the weight change data of the counterweight device 112 and the first lifting length data of the traction device 111.

[0044] Exemplarily, the intelligent overhead crane system 110 is a lifting equipment that integrates advanced technologies such as artificial intelligence and automatic control. The traction device 111 can be, for example, a winch rope with a winch, and the counterweight device 112 can be, for example, a heavy hammer. The heavy hammer can be divided into an external conical barrel and an internal electrode paste. The external material is steel that is exactly the same as the material of the electrode shell, forming a conical iron barrel. The inside of the iron barrel can be filled with electrode paste. Therefore, when the heavy hammer falls into the electrode barrel under special circumstances, it can be used as a material for electrode roasting in the electric arc furnace, and there is no need for salvage; the intelligent overhead crane system 110 can be installed above the electrode shell. The (electrode) electrode shell can include multiple, for example, three. The intelligent overhead crane system 110 can control the lifting and lowering of the winch rope based on control instructions to control the lifting and lowering of the heavy hammer above multiple electrode shells, thereby ensuring that the heavy hammer falls accurately in the center of each electrode shell according to the measurement process, and thus hangs on the surface of the electrode paste in the electrode shell.

[0045] Exemplarily, the weighing system 120 may be, for example, a high-precision weighing sensor, which can measure the weight change of the weight (counterweight device 112) in real time, reliably and accurately during the process of the weight being lifted to the surface of the electrode paste column through the weighing system 120; the lifting length encoder 130 may be, for example, a high-precision absolute value encoder, which can measure the lifting length (first lifting length data) of the weight in real time and reliably during the process of the weight being lifted to the surface of the electrode paste column, thereby measuring the height of the electrode paste (column); the paste measurement control module may be, for example, an automatic paste measurement control system, which can issue a winch rope lifting command and a stop command (control instruction) to the intelligent overhead crane, and determine whether the weight has been hung on the surface of the electrode paste column in the electrode shell according to the change in the measurement data of the weighing system 120, thereby measuring the height data of the electrode paste column. The height data of the electrode paste column can be expressed as the height between the bottom of the electrode shell and the surface of the electrode paste column. According to the measurement process requirements, the intelligent overhead crane system 110 can be controlled by the paste measurement control module to move to the top of the corresponding electrode shell, and ensure the accuracy of the measurement of the weighing system 120 and the lifting length encoder 130 during the descent of the heavy hammer, and record the height data of the automatically measured electrode paste in real time.

[0046] The measurement frequency of the electrode paste column can be set at a preset time interval, such as once every 40 minutes or one hour. It can also be measured based on peripheral data such as current and voltage to preliminarily determine whether there is any abnormality in the operation of the electric arc furnace. It can also be measured when there is no external abnormality to prevent abnormalities in the furnace from causing danger. There is no specific limitation.

[0047] In the technical solution of the embodiment of the present application, the intelligent overhead crane system controls the lifting and lowering of the traction device based on the received control instructions, and lifts the counterweight device connected to one end of the traction device to the surface of the electrode paste column in the electrode shell. The weighing system measures the weight change data of the counterweight device during the process of lifting the counterweight device to the surface of the electrode paste column, records the first lifting length data of the traction device through the lifting length encoder, and sends control instructions to the intelligent overhead crane system through the paste measurement control module, and measures the height data of the electrode paste column based on the weight change data of the counterweight device and the first lifting length data of the traction device. It can automatically measure the height of the electrode paste column, replace manual operation, improve measurement accuracy and efficiency, and reduce safety risks. It adopts advanced sensor technology and data processing algorithms, can monitor the paste height and distribution in the electric arc furnace in real time, automatically measure the height of the electrode paste column and add paste, and improve measurement accuracy and efficiency.

[0048] For example, the operation control system 100 for the electrode paste for the submerged arc furnace further includes: an automatic paste adding system (for details, refer to Figure 1B ).

[0049] The automatic paste adding system is configured to add electrode paste to the electrode shell when the height data of the electrode paste column meets a first preset threshold value, so that the height data of the electrode paste column reaches the target height data.

[0050] Specifically, the first preset threshold value can be, for example, a critical value of the electrode paste column height set according to a specific production process, which causes abnormal operation of the submersible arc furnace and requires the addition of electrode paste. The target height data can be, for example, the optimal electrode paste column height for the submersible arc furnace to operate stably, which is analyzed and sorted out based on long-term production data analysis and experience summary, and is recorded as Loptimal. For example, when the measured electrode paste column height data reaches an artificially preset critical value, paste can be added to the electrode shell to make the height of the electrode paste column reach the optimal value, thereby ensuring the stable operation of the submersible arc furnace.

[0051] In the technical solution of the embodiment of the present application, when the height data of the electrode paste meets the first preset threshold, the automatic paste adding system adds electrode paste to the electrode shell so that the height data of the electrode paste column reaches the target height data, thereby automatically measuring the amount of paste added and adding paste, replacing manual operation, significantly improving work efficiency, and improving measurement accuracy and stability.

[0052] like Figure 1B As shown, the automatic paste adding system includes: a paste adding device 140 and a paste adding control module (not shown in the figure).

[0053] The paste adding device 140 is configured to add electrode paste of target weight data into the electrode shell so that the height data of the electrode paste column reaches the target height data; the paste adding control module is configured to send a paste adding instruction to the intelligent overhead crane system 110 when the height data of the electrode paste column meets a first preset threshold; wherein the intelligent overhead crane system 110 is further configured to control the lifting and lowering of the traction device 111 based on the paste adding instruction, so as to lift the paste adding device 140 connected to one end of the traction device 111 to the surface of the electrode shell for adding paste.

[0054] For example, the paste adding device 140 may include an automatic unloading bin 141, a mobile trolley 142, a paste adding hopper 143, a material unloading weighing system 144, and a ground track 145. When the height data of the electrode paste column meets the critical value (the first preset threshold), the automatic paste adding control system (paste adding control module) issues a paste adding command, and the intelligent overhead crane system 110 moves to the top of the electrode shell to be added with paste, and uses a sling to lift the electrode cover on the electrode shell (see the electrode in the figure below). Figure 2 ), and transported to the cover placement area, the mobile trolley 142 moves the paste hopper 143 to the discharge port of the automatic unloading bin 141 through the ground track 145 according to the paste adding command, the automatic paste adding control system controls the automatic unloading bin 141 to start unloading, and measures the weight of the electrode paste in the paste hopper 143 in real time through the unloading weighing system 144. When the unloading weighing system 144 shows that the weight of the electrode paste reaches a certain weight (target weight), the automatic unloading bin 141 stops unloading, and the automatic paste adding control system controls the mobile trolley 142 to transport the paste hopper 143 to the top of the corresponding electrode shell. For example, the intelligent overhead crane system 110 can, based on the paste adding instruction, pull the paste hopper 143 containing the target weight of electrode paste in the paste adding device 140 to the surface of the electrode shell through the traction device 111 and add paste, so that the height data of the electrode paste in the electrode shell reaches the target height data.

[0055] In the technical solution of the embodiment of the present application, electrode paste of target weight data is added to the electrode shell by a paste adding device so that the height data of the electrode paste column reaches the target height data. When the height data of the electrode paste column meets the first preset threshold value, a paste adding instruction is sent to the intelligent overhead crane system by the paste adding control module, and the intelligent overhead crane system controls the lifting and lowering of the traction device based on the paste adding instruction to lift the paste adding device connected to one end of the traction device to the surface of the electrode shell for adding paste. Through the application of this system, the manual operation problem in the process of adding and measuring paste is successfully solved, and the precise optimization control of the process is achieved, which not only helps to improve the production efficiency and product quality of the electric arc furnace, but also reduces the production cost for the enterprise and enhances the market competitiveness. In addition, the intelligent and automated features of the system also provide operators with a safer and more comfortable working environment, reducing the interference and influence of human factors on the production process.

[0056] Figure 2 A schematic diagram of an electrode for an electric arc furnace according to an embodiment of the present application is shown.

[0057] like Figure 2 As shown, the electrode 200 includes an electrode cover 201 and an electrode shell 202, and the interior of the electrode shell 202 is filled with electrode paste ( Figure 3 203), the electrode cover 201 covers the opening of the electrode shell 202. The electrodes in the electric arc furnace may include multiple electrodes, for example, three. The electrode cover 201 can prevent oxygen in the air from contacting the electrode paste, reducing oxidation and contamination of the electrode paste. When it is necessary to add paste, the electrode cover 201 can be moved to the cover placement area by a sling to add paste, and after stopping the addition of paste, the electrode cover 201 is covered on the electrode shell 202.

[0058] Based on the above-mentioned operation and control system of electrode paste for electric arc furnace, it is possible to automatically measure the accurate height of the electrode paste column, accurately calculate the amount of paste required based on the actual electrode paste consumption, and accurately add paste, thereby realizing the automation, unmanned and refined management of the entire paste measurement and addition process, which is described in detail below.

[0059] Exemplarily, the paste measurement control module is further configured to determine the first lifting length data of the traction device when the weight change data of the counterweight device meets the preset conditions; then, based on the first lifting length data, determine the height data of the electrode paste column.

[0060] Specifically, when the weight change data of the weight hammer descends to the weighing system and decreases, the preset condition is met, indicating that the weight hammer has just been lowered to the surface of the electrode paste column. Then, based on the first lifting length data of the hoisting rope when the weight hammer is lifted to the surface of the electrode paste column measured by the lifting length encoder, the distance between the height of the hoist and the surface of the electrode paste column in the electrode shell can be obtained, thereby determining the height data of the electrode paste column.

[0061] In the technical solution of the embodiment of the present application, the paste measurement control module determines the first lifting length data of the traction device when the weight change data of the counterweight device meets the preset conditions, and then determines the height data of the electrode paste column based on the first lifting length data, thereby accurately and reliably measuring the height of the electrode paste column automatically, replacing manual operation, improving measurement accuracy and efficiency, and reducing safety risks.

[0062] The following combination Figure 3 , specifically describes how the paste measurement control module determines the height data of the electrode paste column based on the first lifting length data.

[0063] Figure 3 A measurement schematic diagram of an electrode paste column according to an embodiment of the present application is shown.

[0064] like Figure 3As shown, the paste measurement control module is further configured to obtain first height data based on the first lifting length data, wherein the first height data includes the distance between the traction device 111 and the surface of the electrode paste column; then, based on the height difference between the first height data and the second height data, determine the height data of the electrode paste column, wherein the second height data represents the distance between the traction device 111 and the bottom of the electrode shell 202.

[0065] Specifically, refer to Figure 3 When the intelligent overhead crane system 110 controls the weight to drop onto the electrode paste in the electrode shell 202, the weight of the weighing sensor changes immediately, approaching no-load (no weight of the weight at all), indicating that the weight has touched the electrode paste in the electrode shell 202. At this time, the length measured by the lifting length encoder 130 is the height from the hoist height to the electrode paste column in the electrode shell 202 (first height data), recorded as L 自测 The height from the hoist to the bottom of the electrode shell 202 is fixed, denoted as L 卷 (second height data), thus, the paste measurement control module can calculate the actual electrode paste column height in the electrode shell 202 as shown in formula (1):

[0066] L 糊 =L 卷 -L 自测 (1)

[0067] Among them, L 糊 is the height of the electrode paste column, L 卷 is the height from the hoist to the bottom of the electrode shell 202 (second height data), and L self-measurement is the height from the hoist height to the electrode paste column in the electrode shell 202 (first height data).

[0068] In the technical solution of the embodiment of the present application, the paste measurement control module obtains the first height data according to the first lifting length data of the traction device, and then determines the height data of the electrode paste based on the height difference between the first height data and the second height data, thereby automatically measuring the height of the electrode paste column, significantly improving work efficiency, improving measurement accuracy and stability, and providing operators with a safer and more comfortable working environment, reducing the interference and influence of human factors on the production process.

[0069] Based on the electrode paste column height measured by the paste measurement control module, the automatic paste adding system can monitor the electrode pressure release (electrode paste consumption) and automatically calibrate according to the changes in data, so as to accurately calculate the weight of electrode paste to be added and automatically add paste to make the electrode paste column reach the target height data. The specific instructions are as follows.

[0070] Exemplarily, the weighing system is further configured to measure the weight change data of the paste adding device during the process of the paste adding device being lifted and lowered to the surface of the electrode shell, and the lifting length encoder is further configured to record the second lifting length data of the traction device when the weight change data of the paste adding device meets the preset conditions; the paste adding control module is further configured to determine and store the height data of the electrode shell based on the second lifting length data, and determine the target weight data based on the height data of the electrode paste column and the height data of the electrode shell; wherein the height data of the electrode shell represents the distance between the traction device and the surface of the electrode shell.

[0071] Specifically, the intelligent overhead crane transports the paste hopper to the top of the corresponding electrode shell. In the process of the paste hopper being lifted and lowered to the surface of the electrode shell, the weight change data of the paste hopper is measured by the weighing system and recorded in real time using the lifting length encoder. When the paste hopper slowly descends to the point where the weighing system of the intelligent overhead crane is reduced, the preset conditions are met, indicating that the paste hopper is just lowered onto the electrode shell. At this time, the length recorded by the lifting length encoder of the intelligent overhead crane is the second lifting length data. The second lifting length represents the height between the traction device and the surface of the electrode shell, thereby determining the height data of the electrode shell and saving the data in the automatic paste adding control system. Based on the height data of the electrode paste column and the height data of the electrode shell, the weight data of the electrode paste to be added is obtained, and paste is added based on this to optimize the height of the electrode paste column, thereby ensuring the stable operation of the electric arc furnace.

[0072] In the technical solution of the embodiment of the present application, the weight change data of the paste adding device is measured by the weighing system during the process of the paste adding device being lifted and lowered to the surface of the electrode shell. The second lifting length data of the traction device is recorded by the lifting length encoder when the weight change data of the paste adding device meets the preset conditions. The height data of the electrode shell is determined and stored based on the second lifting length data by the paste adding control module, and the target weight data is determined based on the height data of the electrode paste column and the height data of the electrode shell. The electrode paste consumption is then accurately calculated based on the height data of the electrode paste column and the height data of the electrode shell to add paste, thereby realizing automated, unmanned and refined management of the entire paste measuring and adding process.

[0073] Exemplarily, the height data of the electrode shell includes a first height difference between the height data of the current electrode shell and the height data of the previous electrode shell; the paste measurement control module is further configured to calculate the first paste addition length data based on the second height difference between the target height data and the height data of the electrode paste column; the paste addition control module is further configured to calculate and determine the second paste addition length data based on the first height difference between the height data of the current electrode shell and the height data of the previous electrode shell, and determine the target weight data based on the first paste addition length data and the second paste addition length data.

[0074] First, combine Figure 4 Describe how to determine the first paste length data through the paste detection control module.

[0075] Figure 4 A schematic diagram of calculating the first blur length data according to an embodiment of the present application is shown.

[0076] For example, Figure 4 As shown, based on long-term production data analysis and experience summary, the optimal electrode paste column height of the submerged arc furnace is analyzed and sorted out, that is, the target height data is recorded as L 优 , the preliminary paste length can be automatically measured and calculated, that is, the first paste length data, as shown in formula (2):

[0077] L 计 =L 优 -L 糊 (2)

[0078] Among them, L 计 The first fuzzy length data, L 优 is the target height data, L 糊 is the electrode paste column height. However, regardless of the optimal electrode paste column height L 优 , or the electrode paste column height L calculated by the paste measurement control module 糊 There will be some errors, especially under some abnormal working conditions, so L 计 It cannot be used directly as the basis for automatic blurring.

[0079] In the technical solution of the embodiment of the present application, the paste measurement control module obtains the first paste adding length data based on the second height difference between the target height data and the height data of the electrode paste column, thereby preliminarily and automatically measuring the height of the electrode paste to be added, ensuring the stable operation of the electric arc furnace and improving the measurement accuracy and stability.

[0080] Next, combine Figure 5 and Figure 6 The following describes in detail how to determine the second blur length data by the blur control module.

[0081] For example, the production process of the submerged arc furnace requires that during production, the electrodes need to be continuously pressed downward into the submerged arc furnace. The electrodes are continuously consumed in the submerged arc furnace. Therefore, when the consumption reaches a certain level, it is necessary to add an electrode shell and add electrode paste to the electrode shell. The length of the electrode pressed each time is as follows:

[0082] The length L of the electrode pressed into the lower electrode furnace at time t1 t1 ;

[0083] The length L of the electrode pressed into the lower electrode furnace at time t2 t2 ;

[0084] The length L of the electrode pressed into the lower electrode furnace at time t3 t3 ;

[0085] …

[0086] At time ti, the length L of the electrode pressed into the lower electrode furnace ti ;

[0087] The actual electrode consumption length is obtained by superimposing the real-time compression and release statistics of the electrode as shown in formula (3):

[0088] L 压 =L t1 +L t2 +L t3 +……+L ti (3)

[0089] Among them, L 压 The actual length of electrode consumption, theoretically the amount of paste added automatically = the actual length of electrode consumption, the amount of electrode paste added is equal to the amount of electrode paste consumed. However, in actual production, due to the weight of the electrode itself and frequent pressing and releasing, errors may occur, and each error will be superimposed, resulting in the final statistically obtained L 压 The error is large, so L 压 It cannot be used directly as a basis for automatic blurring.

[0090] Therefore, the actual electrode consumption length L obtained by superimposing the real-time electrode pressure and release statistics can be calculated and corrected based on the electrode shell height data during automatic paste addition. 压 , and the correction result is used as the second blur length data, which is described in detail below.

[0091] Figure 5 One of the second blur length data calculation schematic diagrams of an embodiment of the present application is shown.

[0092] For example, Figure 5 As shown, the blurring control module calculates the second blurring length data based on the first height difference between the height data of the current electrode shell 202 and the height data of the previous electrode shell 202. For example, when the first height difference between the height data of the current electrode shell 202 and the height data of the previous electrode shell 202 is greater than or equal to zero, the second blurring length data includes the first height difference.

[0093] Specifically, continue to refer to Figure 5 , read the actual measured and recorded electrode shell 202 height (the distance between the traction device 111 and the surface of the electrode shell 202) h during the current paste addition process t , and then calculate the height difference of the electrode shell 202 between the two time intervals of adding paste (the first height difference), as shown in formula (4):

[0094] Δh=h ti -h ti-1 (4)

[0095] Among them, Δh is the time between adjacent blurring i -t i-1 The height difference of the electrode shell 202 during the time period, h ti is the current height of the electrode shell 202, h ti-1 is the height of the preceding electrode shell 202 (the height of the electrode shell 202 represents the distance between the traction device 111 and the surface of the electrode shell 202).

[0096] When Δh≥0, the electrode shell 202 is i -t i-1 The consumption during this period is L 壳 =Δh, since the consumed electrode shell 202 is consumed in the ore-fired furnace by pressing the electrode downward, therefore, at t i -t i-1 The length of electrode paste that needs to be added during this period is L 壳 =L 压 , which is used as the actual electrode consumption length L obtained by superimposing the real-time electrode pressure and release statistics. 压 The calibration value, that is, the second added blur length data.

[0097] Figure 6 The second schematic diagram of calculating the second blurred length data according to an embodiment of the present application is shown.

[0098] For example, Figure 6 As shown, the blurring control module calculates the second blurring length data based on the first height difference between the height data of the current electrode shell 202 and the height data of the previous electrode shell 202. For example, when the first height difference between the height data of the current electrode shell 202 and the height data of the previous electrode shell 202 is less than zero, the second blurring length data includes the sum of the first height difference and the third blurring length data; wherein the third blurring length data represents the height of the electrode shell 202 added between the previous blurring time and the current blurring time.

[0099] Specifically, continue to refer to Figure 6 , based on the adjacent blurring time t obtained above i -t i-1 The height difference Δh of the electrode shell 202 during the time period is Δh<0, indicating that at t i- t i-1 During this period, a new electrode shell 202 ( Figure 6The upper portion of the electrode shell 202 in the middle left figure is shaded), the standard height of the added electrode shell 202 is h0, that is, the third added paste length data, so the electrode shell 202 is at t i -t i-1 The consumption during this period is L 壳 =Δh+h0, which is L 压 The calibration value and the second add the fuzzy length data.

[0100] Based on the calibration of the actual consumption length of the electrode by the above-mentioned paste adding control module, the height difference of the electrode shell 202 in two adjacent time periods can be used to calibrate the actual consumption length of the electrode again. 壳 =L 压 The actual electrode consumption length L is obtained by superimposing the real-time compression and release statistics of the electrode. 压 Perform calibration.

[0101] In the technical solution of the embodiment of the present application, the first paste adding length data is calculated by the paste measuring control module according to the second height difference between the target height data and the height data of the electrode paste column. The paste adding control module determines that the second paste adding length data is the first height difference when the first height difference between the height data of the current electrode shell and the height data of the previous electrode shell is greater than or equal to zero. When the first height difference between the height data of the current electrode shell and the height data of the previous electrode shell is less than zero, the second paste adding length data is determined to include the sum of the first height difference and the third paste adding length data, and the target weight data is determined based on the height data of the electrode paste column and the height data of the electrode shell. Therefore, a special calibration algorithm is used to overcome the error generated during automatic measurement, and the paste measuring results are automatically calibrated to ensure the accuracy and reliability of the measurement results, thereby ensuring the accuracy of paste measurement and real-time adjustment of paste adding, realizing precise process optimization control, and ensuring the stable operation of the entire electric arc furnace. In addition, the algorithm also has self-learning and self-adaptive capabilities, which can continuously optimize calibration parameters and improve measurement accuracy and stability.

[0102] Exemplarily, the paste adding control module determines the target weight data based on the first paste adding length data and the second paste adding length data. For example, first, the first paste adding length data and the second paste adding length data are weighted to obtain the target paste adding length data, wherein within a preset time, when the number of electrode pressure discharges in the submersible arc furnace is less than a second preset threshold, the weight of the first paste adding length data is less than the weight of the second paste adding length data; when the number of electrode pressure discharges in the submersible arc furnace is greater than or equal to the second preset threshold, the weight of the first paste adding length data is greater than the weight of the second paste adding length data; then, the target weight data is calculated based on the product of the target paste adding length data, the cross-sectional area of ​​the electrode shell, and the density of the electrode paste.

[0103] Specifically, the blurring control module performs weighted processing on the first blurring length data and the second blurring length data to obtain target blurring length data. For example, a first product is obtained according to the weight of the first blurring length data and the first blurring length data, and a second product is obtained according to the weight of the second blurring length data and the second blurring length data; the target blurring length data is obtained by dividing the sum of the first product and the second product by the sum of the weight of the first blurring length data and the weight of the second blurring length data.

[0104] For example, based on the corrected actual automatic paste adding length L, i.e., the first paste adding length data and the second paste adding length data, a weighted average method is used to perform comprehensive measurement to obtain target paste adding length data. The target paste adding length data represents the length of electrode paste that needs to be added to make the electrode paste column reach the target height after calibration, as shown in formula (5):

[0105] L=(a×L 计 +b×L 压 ) / (a+b)(5)

[0106] Among them, L is the target pasting length data, a is the paste column weight coefficient (for the electrode paste column height data obtained by automatic measurement, that is, the weight of the first pasting length data), and b is the pressure release weight coefficient (for the statistical consumption of electrode pressure release, that is, the weight of the second pasting length data).

[0107] Through a large amount of actual data statistics, under different working conditions, the paste column weight coefficient a and the pressure release weight coefficient b are different. Within the preset working time of the submerged arc furnace, for example, 8 hours, according to the actual furnace conditions, it is necessary to perform specific weighted calculations on the target paste length data. When the furnace condition is stable, when the number of electrode pressure releases is less than the second preset threshold, it means that the electrode pressure release is not frequent. At this time, the pressure release error is relatively small, and the target length is calculated based on the actual furnace conditions. 压 Mainly, that is, a<b, the specific size is analyzed according to the actual situation, and the second preset threshold can be set according to the process requirements; when the furnace condition is unstable, when the number of electrode pressing and releasing is greater than or equal to the second preset threshold, it means that the electrode pressing and releasing is too frequent and the pressing and releasing amount error is large, and L 计 Mainly, that is, a>b, the specific size is analyzed according to the actual situation.

[0108] Then, according to the target paste length data, the cross-sectional data of the electrode shell, and the density of the electrode paste, the specific paste weight (target weight data) can be calculated, as shown in formula (6):

[0109] m=L×s×ρ (6)

[0110] Where s is the cross-sectional area of ​​the electrode shell (the electrode shell can be a cylinder), and ρ is the electrode paste density.

[0111] In the technical solution of the embodiment of the present application, the first paste adding length data and the second paste adding length data are weightedly processed by the paste adding control module to obtain the target paste adding length data, and then the target weight data of the electrode paste is obtained according to the product of the target paste adding length data, the cross-sectional area of ​​the electrode shell, and the density of the electrode paste. The paste adding amount is automatically adjusted according to the preset process parameters, the paste measurement results are automatically calibrated, and the calibration parameters can be continuously optimized, which greatly reduces the errors occurring in the measurement process, thereby ensuring the accuracy of paste measurement and real-time adjustment of paste adding, improving lean control in the production process, and ensuring the stable operation of the entire electric arc furnace.

[0112] Figure 7 A schematic diagram of automatic paste addition in an embodiment of the present application is shown.

[0113] For example, Figure 7 As shown, the weighing system 120 is further configured to measure the weight data of the remaining electrode paste in the paste adding device 140 and send the weight data of the remaining electrode paste to the paste adding control module during the paste adding process; the paste adding control module is further configured to send a stop paste adding instruction to the intelligent overhead crane system 110 when the weight data of the remaining electrode paste is zero based on the received weight data of the remaining electrode paste.

[0114] Specifically, continue to refer to Figure 7 According to the weight data of the electrode paste, the automatic paste adding system performs the following working process of adding paste:

[0115] (1) The automatic paste adding control system issues a paste adding command. The intelligent overhead crane first moves to the top of the electrode shell 202 where paste needs to be added, and uses a hoist to lift the electrode cover 201 on the electrode shell 202 and move it to the cover placement area.

[0116] (2) The automatic paste adding control system sends a command to the mobile car 142.

[0117] (3) The mobile trolley 142 moves the paste adding hopper 143 (paste adding device 140) to the discharge port of the automatic unloading bin 141 via the ground track.

[0118] (4) There is a material weighing system 120 on the track below the discharge port, which can measure the weight of the electrode paste in the paste hopper 143 in real time.

[0119] (5) The automatic paste adding control system calculates the weight of the electrode paste that needs to be added, which is recorded as m. The details are described in the above process.

[0120] (6) The automatic paste adding control system controls the automatic unloading bin 141 to start unloading. When the unloading weighing system 120 shows that the weight of the electrode paste reaches m, the automatic unloading bin 141 stops unloading, and the automatic paste adding control system issues a moving command to the mobile cart 142.

[0121] (7) The mobile trolley 142 moves the paste hopper 143 loaded with electrode paste of weight m to the transport position, and the automatic paste adding control system sends a transport command to the intelligent overhead crane.

[0122] (8) The intelligent overhead crane moves the paste hopper 143 to the top of the corresponding electrode shell 202, and slowly lowers the paste hopper 143 to the level of the intelligent overhead crane's weighing system 120 by means of the hoisting rope (traction device 111). When the weight of the paste hopper 143 decreases, it means that the paste hopper 143 is just placed on the electrode shell 202, and the paste hopper 143 starts to add paste. At this time, the length recorded by the lifting length encoder 130 of the intelligent overhead crane is the height h of the electrode shell 202. ti The data is saved in the automatic paste adding control system. The height of the electrode shell 202 recorded when the paste was added last time is h ti-1 , and save the data in the automatic paste control system.

[0123] (9) During the paste adding process, the intelligent overhead crane monitors the weight of the electrode paste in the paste adding hopper 143 in real time through the weighing system 120 installed on the intelligent overhead crane, and transmits the weight data to the automatic paste adding control system in real time. When the weight of the electrode paste is 0, the automatic paste adding control system sends a stop paste adding command to the intelligent overhead crane. At this time, the height data of the electrode paste column reaches the target height data.

[0124] (10) The intelligent overhead crane transports the paste hopper 143 filled with paste to the mobile trolley 142 in the transport area.

[0125] (11) The mobile trolley 142 moves the paste hopper 143 to the discharge port of the automatic unloading bin 141 via the ground track.

[0126] (12) The automatic paste adding control system issues a paste adding completion command, and the intelligent overhead crane runs to the placement area of ​​the electrode cover plate 201. The electrode cover plate 201 is lifted to the top of the electrode shell 202 where the paste adding is completed by using a sling, and then gradually descends to the height of the electrode shell 202, and the electrode cover plate 201 is covered on the electrode shell 202.

[0127] In the technical solution of the embodiment of the present application, the weighing system measures the weight data of the remaining electrode paste in the paste adding device during the paste adding process, and sends the weight data of the remaining electrode paste to the paste adding control module. The paste adding control module sends a stop paste adding instruction to the intelligent overhead crane system based on the received weight data of the remaining electrode paste when the weight data of the remaining electrode paste is zero, so that when the weight data of the remaining electrode paste is zero, the height data of the electrode paste column reaches the target height data, thereby realizing automatic paste adding and measuring, improving operation accuracy and efficiency, reducing safety risks, bringing significant economic and social benefits to the electric arc furnace industry, and having broad application prospects and promotion value.

The operation control method is applied to the operation control system of the electrode paste for a submerged arc furnace described above.

[0130] In step S810, the intelligent overhead crane system controls the lifting of the traction device based on the received control instruction, so as to lift the counterweight device connected to one end of the traction device to the surface of the electrode paste column in the electrode shell.

[0131] Step S820: Measure the weight change data of the counterweight device through the weighing system during the process of the counterweight device being raised and lowered to the surface of the electrode paste column.

[0132] Step S830: Record the first lifting length data of the traction device through the lifting length encoder.

[0133] Step S840: Send a control instruction to the intelligent overhead crane system through the paste measurement control module, and measure the height data of the electrode paste column based on the weight change data of the counterweight device and the first lifting length data of the traction device.
