[0030] Embodiment 1

[0031] Figure 1 The following is a flowchart of a soft stirring timing method for metal refining provided in Embodiment 1 of the present invention. This embodiment is applicable to the scenario of pyrometallurgical refining of metals, especially the control of the soft stirring process. This method can be executed by a soft stirring timing device for metal refining, and this device can be implemented in the form of hardware and / or software, and this device can be configured in an electronic device. As Figure 1 shown, this method includes:

[0032] S110. Obtain detection data in the metallurgical bath according to a preset detection period; the detection data includes at least one of the bottom blowing gas flow rate and the pressure.

[0033] This solution can be executed by a refining control platform, which can control the metal refining process to ensure the quality of metal refining products. Metal refining is a process of removing impurities from crude metal by physical or chemical means to improve the purity of the metal. The core goal of metal refining is to adjust the chemical composition and improve the physical properties. Pyrometallurgical refining of metals is usually carried out in a metallurgical bath, and impurities in the crude metal are removed by slag making, volatilization or oxidation at high temperatures. The pyrometallurgical refining process of metals can include steps such as feeding, heating, soft stirring, vacuum pumping and casting, and soft stirring is an important part of it.

[0034] It is understandable that in the soft stirring process, the bottom-blowing gas flow rate needs to be within a certain range. When blowing gas at a gas flow rate outside this range, the purpose of soft stirring cannot be achieved, that is, the effect of promoting the floating of impurities cannot be realized. The bottom-blowing gas flow rate can affect the pressure in the metallurgical bath. Therefore, the size of the bottom-blowing gas flow rate can be judged based on the pressure condition in the metallurgical bath, and then whether the purpose of soft stirring is achieved can be judged. At the same time, abnormal situations such as air leakage may occur during the bottom-blowing gas process, resulting in abnormal pressure in the metallurgical bath. The abnormal pressure in the metallurgical bath can be used to characterize whether there is an abnormality during the bottom-blowing gas process.

[0035] A variety of detection devices can be deployed in the metallurgical bath to detect the metal refining process in the metallurgical bath. Each detection device can perform detection according to a preset detection period, for example, once every 0.001 s. The refining control platform can communicate with the detection devices deployed on the metallurgical bath to obtain the detection data in the metallurgical bath. According to the characteristics of the soft stirring process, a pressure measuring device can be deployed in the metallurgical bath, and the pressure measuring device can be used to measure the melt pressure in the metallurgical bath. The metallurgical bath can also be provided with a flow measuring device at the gas inlet at the bottom for measuring the bottom-blowing gas flow rate.

[0036] The refining control platform can obtain the detection data in the metallurgical bath during the metal refining process. Among them, the detection data can include at least one of the bottom-blowing gas flow rate and the pressure. The refining control platform can obtain the detection data of one detection period in the metallurgical bath according to the preset detection period each time, or can obtain the detection data of each detection period in the metallurgical bath at the end of the metal refining. According to the detection data in the metallurgical bath, the refining control platform can judge whether the soft stirring process is normally executed and record the soft stirring time of normal execution to achieve accurate timing of soft stirring.

[0037] S120. Judge whether the detection data of the current detection period is within the preset reference range.

[0038] The refining control platform can judge whether the detection data of the current detection period is within the preset reference range. If the detection data of the current detection period is not within the preset reference range, then execute S130. If the detection data of the current detection period is within the preset reference range, then execute S140.

[0039] S130. Do not perform soft stirring timing for the current detection period.

[0040] S140. Perform soft stirring timing for the current detection period.

[0041] S150. Determine the current soft stirring timing duration according to the pre-determined soft stirring timing start time and the number of detection periods for which soft stirring timing is performed before the end of the current detection period.

[0042] The start time of soft stirring timing can be the trigger time when the soft stirring process starts. In a feasible solution, the user terminal of the refining control platform can set a physical button or a virtual button for indicating the start of soft stirring, and the start time of soft stirring timing can be the time when the process personnel press or click the soft stirring start button. In another feasible solution, the refining control platform can track each process step of metal refining, determine whether the previous process step of the soft stirring process is completed, if completed, then start the soft stirring timing, and record the start time of soft stirring timing. For example, if the previous process before soft stirring is heating, the refining control platform can collect the heating time of the metallurgical bath, and based on the heating time, determine the start time of soft stirring timing.

[0043] It can be understood that if the refining control platform obtains the detection data of each detection cycle each time, the refining control platform can judge whether to perform soft stirring timing for the current detection cycle according to the detection data of the current detection cycle. If soft stirring timing is performed for the current detection cycle, the refining control platform can determine the current soft stirring timing duration according to the pre-determined start time of soft stirring timing and the number of detection cycles for which soft stirring timing is performed before the end of the current detection cycle. Specifically, the current soft stirring timing duration is the sum of the cycle lengths of each detection cycle for which soft stirring timing is performed after the start time of soft stirring timing and before the end of the current detection cycle.

[0044] S160. Judge whether the current soft stirring timing duration reaches the preset soft stirring duration.

[0045] The refining control platform can judge whether the current soft stirring timing duration reaches the preset soft stirring duration. If not, execute S170; if so, execute S180.

[0046] S170. Update the next detection cycle to the current detection cycle.

[0047] If the current soft stirring timing duration does not reach the preset soft stirring duration, the refining control platform can continue to control the metallurgical bath to perform soft stirring, then update the next detection cycle to the current detection cycle, and return to execute S120 until the current soft stirring timing duration reaches the preset soft stirring duration.

[0048] S180. Output the soft stirring timing result.

[0049] If the current soft stirring timing duration reaches the preset soft stirring duration, the refining control platform can stop the soft stirring and output the soft stirring timing result in the metal refining process. It should be noted that the soft stirring timing result can include information such as the soft stirring timing duration, whether soft stirring timing is performed for each detection cycle, and whether the soft stirring timing is interrupted.

[0050] The technical solution of the embodiment of the present invention obtains the detection data in the metallurgical molten bath according to a preset detection period; the detection data includes at least one of the bottom blowing gas flow rate and the pressure; if the detection data in the current detection period is not within the preset reference range, the soft stirring timing is not performed in the current detection period; if the detection data in the current detection period is within the preset reference range, the soft stirring timing is performed in the current detection period; the current soft stirring timing duration is determined according to the pre-determined soft stirring timing start time and the number of detection periods for which the soft stirring timing is performed before the end of the current detection period; if the current soft stirring timing duration has not reached the preset soft stirring duration, the next detection period is updated as the current detection period, and it is returned to determine whether the detection data in the current detection period is within the preset reference range; if the current soft stirring timing duration reaches the preset soft stirring duration, the soft stirring timing result is output. This technical solution solves the problem of inaccurate soft stirring timing. By collecting the detection data in the metallurgical molten bath, the refined timing of soft stirring is realized, the accuracy of soft stirring timing in the metal refining process is improved, and the metal refining quality is guaranteed.

[0051] Embodiment 2

[0052] Figure 2 The flowchart of a soft stirring timing method for metal refining provided by the second embodiment of the present invention. This embodiment is based on the above embodiment and details the determination process of the soft stirring timing start time. As Figure 2 shown, the method includes:

[0053] S201. Detect the first material adjustment event in the metallurgical molten bath to determine the first material adjustment time; detect the first temperature adjustment event in the metallurgical molten bath to determine the first temperature adjustment time; the first material adjustment event is the material adjustment event in the metallurgical furnace before determining the soft stirring timing start time; the first material adjustment time is the detection time of the first material adjustment event; the first temperature adjustment event is the temperature adjustment event in the metallurgical furnace before determining the soft stirring timing start time; the first temperature adjustment time is the detection time of the first temperature adjustment event.

[0054] In this solution, the start time of the soft stirring timing can be determined based on the material adjustment time and the temperature adjustment time in the metallurgical bath. It is easy to understand that before the soft stirring process, process steps such as material adjustment and temperature adjustment need to be carried out in the metallurgical bath. The soft stirring must be carried out after the material adjustment is completed and the temperature adjustment is completed. Therefore, the metallurgical bath can be equipped with material adjustment detection equipment to detect whether there is a material adjustment event in the metallurgical bath. For example, an infrared opposed sensor can be set at the feeding inlet of the metallurgical bath to detect whether materials are added to the metallurgical bath; another example is to set weighing equipment at the bottom of the metallurgical bath to weigh the materials in the metallurgical bath to detect whether a material adjustment event occurs. The temperature adjustment of the metallurgical bath is usually achieved by electrically heating the metallurgical bath. The refining control platform can detect whether there is an energization signal in the metallurgical bath, and then judge whether the temperature adjustment in the metallurgical bath is completed. Temperature measuring equipment can also be deployed in the metallurgical bath to measure the temperature of the melt in the metallurgical bath. The refining control platform can judge whether the temperature adjustment is completed by obtaining the temperature in the metallurgical bath. For example, if the temperature no longer rises, it is determined that the temperature adjustment is completed.

[0055] If there is no start time for the soft stirring timing of the current metal refining, the refining control platform can detect the first material adjustment event in the metallurgical bath. When the first material adjustment event is detected, the first material adjustment time is recorded. At the same time, the refining control platform can detect the first temperature adjustment event in the metallurgical bath. When the first temperature adjustment event is detected, the first temperature adjustment time is recorded. Among them, the first material adjustment event is the material adjustment event in the metallurgical furnace before the start of the soft stirring timing, and the first material adjustment time is the detection time of the first material adjustment event; the first temperature adjustment event is the temperature adjustment event of the metallurgical furnace before the start of the soft stirring timing, and the first temperature adjustment time is the detection time of the first temperature adjustment event. The material adjustment event can be an event of adding or extracting materials into the metallurgical bath, and the temperature adjustment event can be an event of heating or cooling the metallurgical bath.

[0056] S202. Determine the start time of the soft stirring timing according to the first material adjustment time and the first temperature adjustment time.

[0057] The refining control platform can judge whether the material adjustment is completed according to the first material adjustment time. For example, calculate the time difference between the first material adjustment time and the current time. If the time difference is greater than or equal to the preset duration, it is determined that the material adjustment is completed. The refining control platform can also judge whether the temperature adjustment is completed according to the first temperature adjustment time. For example, if the current time is after the first temperature adjustment time and there is no energization heating signal in the metallurgical bath, it is determined that the temperature adjustment is completed. If the material composition adjustment in the metallurgical bath is completed at the current time and the temperature adjustment in the metallurgical bath is completed, the refining control platform can determine that the current time is the start time of the soft stirring timing.

[0058] In a preferred embodiment, after determining the start time of the soft stirring timing, the method further includes:

[0059] Detecting a second material adjustment event in the metallurgical bath and detecting a second temperature adjustment event in the metallurgical bath; the second material adjustment event is a material adjustment event in the metallurgical furnace after determining the start time of the soft stirring timing; the second temperature adjustment event is a temperature adjustment event in the metallurgical furnace after determining the start time of the soft stirring timing;

[0060] If there is a second material adjustment event or there is a second temperature adjustment event, the start time of the soft stirring timing is updated according to a preset timing update principle.

[0061] After the start of the soft stirring timing, it is possible that the process operator adjusts the materials in the metallurgical bath again or adjusts the temperature in the metallurgical bath. For example, if the process operator adds insufficient materials, it is necessary to add materials into the metallurgical bath again and heat the metallurgical bath again. It can be understood that the material adjustment and temperature adjustment after the start of the soft stirring timing will affect the soft stirring effect. For example, the newly added materials will bring the floating impurities back into the melt interior again.

[0062] To overcome the influence of the material adjustment and temperature adjustment after the start of the soft stirring timing, the refining control platform can detect the material adjustment event and temperature adjustment event after the start of the soft stirring timing. If there is a second material adjustment event or there is a second temperature adjustment event, the refining control platform can re-determine the start time of the soft stirring timing according to a preset timing update principle.

[0063] Specifically, the condition for effective soft stirring is the alloying of the melt in the metallurgical bath, that is, when the soft stirring starts, the melt in the metallurgical furnace must be alloyed, otherwise the soft stirring process is invalid. The adjustment of materials and temperature indicates that the materials in the metallurgical bath do not meet the alloying conditions. Therefore, the soft stirring process before the material and temperature adjustment is invalid, and it is necessary to clear the soft stirring timing and re-time the soft stirring process after alloying. The preset timing update principle may include: if there is a second material adjustment event and there is no second temperature adjustment event, update the start time of the soft stirring timing to the moment at a preset time interval after the second material adjustment time; if there is no second material adjustment event and there is a second temperature adjustment event, update the start time of the soft stirring timing to the moment after the second temperature adjustment time; if there are both a second material adjustment event and a second temperature adjustment event, the updated start time of the soft stirring timing satisfies: after the second material adjustment time, after the second temperature adjustment time, and at a time interval greater than or equal to the preset time interval from the second material adjustment time. The preset time interval can be set according to the metal production process.

[0064] After the start time of the soft stirring timing is determined, this solution can continue to detect material adjustment events and temperature regulation events, and correct the start time of the soft stirring timing after detecting a material adjustment event or a temperature regulation event, which is beneficial to improving the accuracy of the soft stirring timing and ensuring the reliability of the soft stirring process.

[0065] S203. Obtain the detection data in the metallurgical bath according to a preset detection period; the detection data includes at least one of the bottom blowing gas flow rate and the pressure.

[0066] S204. Determine whether the detection data of the current detection period is within the preset reference range.

[0067] S205. Do not perform soft stirring timing in the current detection period.

[0068] S206. Perform soft stirring timing in the current detection period.

[0069] S207. Determine the current soft stirring timing duration according to the pre-determined start time of the soft stirring timing and the number of detection periods for which soft stirring timing is performed before the end of the current detection period.

[0070] S208. Determine whether the current soft stirring timing duration reaches the preset soft stirring duration.

[0071] S209. Update the next detection period as the current detection period.

[0072] S210. Output the soft stirring timing result.

[0073] In a feasible solution, the refining control platform can obtain the bottom blowing gas flow rate in the metallurgical bath according to a preset detection period during the metal refining process. If the bottom blowing gas flow rate in the current period is not within the preset flow rate range, soft stirring timing is not performed in the current period. If the bottom blowing gas flow rate in the current period is within the preset flow rate range, soft stirring timing is performed in the current period. The refining control platform can output the soft stirring timing duration up to the current period after the end of the current period. If the soft stirring timing duration output in the current period reaches the preset duration, the soft stirring timing result is output. If the soft stirring timing duration output in the current period does not reach the preset duration, the refining control platform can continue to collect the bottom blowing gas flow rate in the metallurgical bath in the next period to perform the soft stirring timing judgment in the next period until the soft stirring timing duration output in the subsequent period reaches the preset duration.

[0074] In another feasible solution, the refining control platform can obtain the pressure inside the metallurgical bath according to a preset detection period during the metal refining process. If the pressure in the current period is not within the preset pressure range, the soft stirring timing is not performed in the current period; if the pressure in the current period is within the preset pressure range, the soft stirring timing is performed in the current period; after the end of the current period, the refining control platform can output the soft stirring timing duration up to the current period. If the soft stirring timing duration output in the current period reaches the preset duration, the soft stirring timing result is output. If the soft stirring timing duration output in the current period does not reach the preset duration, the refining control platform can continue to collect the pressure inside the metallurgical bath in the next period to determine the soft stirring timing in the next period until the soft stirring timing duration output in the subsequent period reaches the preset duration.

[0075] In a preferred solution, the detection data may include the bottom blowing gas flow rate and pressure. The refining control platform can obtain the bottom blowing gas flow rate and pressure inside the metallurgical bath according to a preset detection period during the metal refining process. If the bottom blowing gas flow rate in the current period is not within the preset flow rate range, or the pressure in the current period is not within the preset pressure range, the soft stirring timing is not performed in the current period; if the bottom blowing gas flow rate in the current period is within the preset flow rate range and the pressure in the current period is within the preset pressure range, the soft stirring timing is performed in the current period; after the end of the current period, the refining control platform can output the soft stirring timing duration up to the current period. If the soft stirring timing duration output in the current period reaches the preset duration, the soft stirring timing result is output. If the soft stirring timing duration output in the current period does not reach the preset duration, the refining control platform can continue to collect the detection data in the next period to determine the soft stirring timing in the next period until the soft stirring timing duration output in the subsequent period reaches the preset duration.

[0076] By judging whether to perform soft stirring timing for each detection period in the above solution, it is beneficial to accurately control the duration of the soft stirring process and ensure the quality stability of the metal refining products.

[0077] In this solution, optionally, after outputting the soft stirring timing result, the method further includes:

[0078] Obtaining the liquid metal component data inside the metallurgical bath after the end of the soft stirring timing;

[0079] Judging whether the soft stirring timing result is abnormal according to the liquid metal component data.

[0080] It is easy to understand that after soft stirring the melt in the metallurgical bath according to the preset soft stirring duration, the melt in the metallurgical bath reacts sufficiently, and the liquid metal composition in the metallurgical bath should be uniform and within the preset composition range. The operating behavior of on-site process operators may lead to misjudgment of the soft stirring timing period. For example, the operating behavior of process operators causes the infrared pair emission device to lose power and fails to detect the feeding event, resulting in an incorrect soft stirring timing result. Therefore, after the soft stirring timing ends, the refining control platform can detect the liquid metal composition in the metallurgical bath to obtain the liquid metal composition data in the metallurgical bath, and based on the liquid metal composition data, determine whether the soft stirring timing result is abnormal.

[0081] Specifically, the liquid metal composition data may include the liquid metal compositions at multiple positions in the metallurgical bath. The refining control platform can determine the liquid metal composition differences between different positions in the metallurgical bath. If the liquid metal composition differences between two positions are greater than the preset composition difference threshold, it indicates that the soft stirring process is not executed sufficiently and the soft stirring timing result is abnormal. The refining control platform can also compare the liquid metal compositions at each position with the preset composition range. If the liquid metal composition at a target position is not within the preset composition range, the soft stirring process is not executed sufficiently and the soft stirring timing result is abnormal.

[0082] This solution can determine whether the soft stirring timing result is normal based on the liquid metal composition after the soft stirring ends, so as to inspect the detection equipment when the soft stirring timing result is abnormal and ensure the reliability of the subsequent soft stirring timing result.

[0083] In this embodiment, after outputting the soft stirring timing result, the method further includes:

[0084] Determine the soft stirring end time according to the soft stirring timing result;

[0085] Judge whether the soft stirring time is abnormal according to the soft stirring end time and the previously obtained casting start time.

[0086] It can be understood that the soft stirring during the metal refining process should be continuous, minimizing the number and duration of interruptions. There should be a certain time interval between the soft stirring process and the casting process. Therefore, after the soft stirring ends, the refining control platform can determine the end time of the soft stirring based on the soft stirring timing result, calculate the time difference between the end time of the soft stirring and the casting start time, and judge whether the continuity of the soft stirring time is abnormal according to the time difference between the end time of the soft stirring and the casting start time. If the time difference between the end time of the soft stirring and the casting start time is less than the preset time interval, the continuity of the soft stirring time is poor, and the refining control platform can determine that the soft stirring time is abnormal and issue an alarm for abnormal soft stirring. If the time difference between the end time of the soft stirring and the casting start time is greater than or equal to the preset time interval, it is determined that the soft stirring time is normal. If the soft stirring time is abnormal, the metallurgical molten pool and the detection equipment deployed inside the metallurgical molten pool can be inspected to judge the cause of the abnormality to ensure the reliability of the subsequent soft stirring process.

[0087] This solution can judge whether the continuity of the soft stirring time is good through the time interval between the casting start time and the end time of the soft stirring, which is conducive to ensuring the strict implementation of the soft stirring process and improving the quality of metal refining products.
