Description

Technical Field

[0001] This invention relates to the field of bag penetration warning, and more specifically, to a method, apparatus, electronic device, and storage medium for intermediate bag penetration warning. Background Technology

[0002] During continuous casting, molten steel from the ladle is poured into the tundish through a single nozzle, continuously impacting the tundish's impact zone. This area, where the refractory material endures the high temperature and pressure of the molten steel, is the most severely corroded part. If the quality of the refractory material or the lining quality fluctuates, or if the impact angle is not properly adjusted, the refractory material at the bottom of the impact zone corrodes too quickly. The tundish cannot withstand the high temperature and pressure of the molten steel, and the bottom of the ladle turns red. Even if detected in time, this will cause production interruption. If not detected in time, the molten steel will penetrate the tundish, posing a significant risk to equipment and personal safety. While increasing the continuous casting time in the tundish can improve production efficiency and reduce fuel and steel consumption, the longer the continuous casting time, the more severe the refractory material corrosion, and the greater the risk of steel penetration.

[0003] Currently, some steel mills use thermal imaging technology to monitor ladles. Theoretically, thermal imaging technology can be used to monitor tundishes, but the presence of flowing molten steel inside the tundish interferes with the thermal imaging display. Furthermore, the contrast of thermal images is inherently low, resulting in poor detail resolution and inaccurate tundish penetration warnings. Summary of the Invention

[0092] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0094] Through extensive research, the inventors discovered that during continuous casting, molten steel is injected into the tundish through a single nozzle, continuously impacting the tundish's impact zone. This area, where the refractory material endures the high temperature and pressure of the molten steel, is the most severely corroded part. If the quality of the refractory material or the lining quality fluctuates, or if the impact angle is not properly adjusted, the refractory material at the bottom of the impact zone corrodes too quickly. The tundish cannot withstand the high temperature and pressure of the molten steel, and the bottom of the ladle turns red. Even if this is detected in time, it will cause production interruption. If it is not detected in time, the molten steel will penetrate the tundish, posing a significant risk to equipment and personal safety. While increasing the continuous casting time in the tundish can improve production efficiency and reduce fuel and steel consumption, the longer the continuous casting time, the more severe the refractory material corrosion, and the greater the risk of steel penetration.

[0095] Currently, some steel mills use thermal imaging technology to monitor ladles. Theoretically, thermal imaging technology can be used to monitor tundishes, but the presence of flowing molten steel inside the tundish interferes with the thermal imaging display. Furthermore, the contrast of thermal images is inherently low, resulting in poor detail resolution and inaccurate tundish penetration warnings.

[0096] In view of the above-mentioned problems, this embodiment provides a method, device, electronic device, and storage medium for tundish penetration warning. It can acquire first temperatures at the bottom of the tundish impact zone within a preset time period, and second temperatures at the outer shell of the tundish within the same preset time period. The tundish consists of a bottom and four outer shells. Based on the first temperatures, trend parameters are calculated; based on the second temperatures, monitoring values ​​are calculated; the molten steel phase line temperature and safe pouring temperature of the tundish are determined; an upper limit value is calculated based on the molten steel phase line temperature and safe pouring temperature; a maximum edge temperature is determined based on the first temperatures, trend parameters, and upper limit value; and a warning temperature is determined based on the maximum edge temperature. The real-time temperature at the bottom of the tundish impact zone is acquired, and penetration warnings are issued for the tundish based on the real-time temperature, monitoring values, maximum edge temperature, and warning temperature. Using the tundish penetration warning method provided in this application, the impact zone of the tundish can be monitored in real time, and penetration warnings can be issued. Compared with thermal imaging technology for tundish monitoring, it has lower investment costs, can be widely promoted, and improves the accuracy of penetration warnings. The solution provided in this embodiment is described in detail below.

[0097] This embodiment provides an electronic device capable of providing early warning of packet penetration in intermediate packages. In one possible implementation, the electronic device can be a user terminal, such as, but not limited to, a server, smartphone, personal computer (PC), tablet computer, personal digital assistant (PDA), mobile internet device (MID), etc.

[0098] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of the electronic device 100 provided in the embodiments of this application. The electronic device 100 may further include... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown. Figure 1 The components shown can be implemented using hardware, software, or a combination thereof.

[0099] The electronic device 100 includes an intermediate package penetration warning device 110, a memory 120, and a processor 130.

[0100] The components of the memory 120 and processor 130 are electrically connected directly or indirectly to achieve data transmission or interaction. For example, these components can be electrically connected to each other through one or more communication buses or signal lines. The intermediate package penetration warning device 110 includes at least one software function module that can be stored in the memory 120 in the form of software or firmware or embedded in the operating system (OS) of the electronic device 100. The processor 130 is used to execute the executable modules stored in the memory 120, such as the software function modules and computer programs included in the intermediate package penetration warning device 110.

[0102] Please refer to Figure 2 , Figure 2 For application Figure 1 The flowchart below shows a method for early warning of intermediate package penetration in an electronic device 100. The method includes a detailed description of each step.

[0103] Step 201: Obtain the first temperature at the bottom of the intermediate impact zone within a preset time period.

[0104] Step 202: Obtain the second temperature of the outer shell of the intermediate package within a preset time period.

[0105] The intermediate package consists of a bottom and four outer shells.

[0106] Step 203: Calculate trend parameters based on each first temperature.

[0107] Step 204: Calculate the monitoring value based on each second temperature.

[0108] Step 205: Determine the phase line temperature of the molten steel in the tundish and the safe pouring temperature.

[0109] Step 206: Calculate the upper limit value based on the phase line temperature of molten steel and the safe pouring temperature.

[0110] Step 207: Determine the maximum edge temperature based on each first temperature, trend parameter, and upper limit value.

[0111] Step 208: Determine the warning temperature based on the maximum edge temperature.

[0112] Step 209: Obtain the real-time temperature at the bottom of the intermediate impact zone.

[0113] Step 210: Provide a bag penetration warning for the intermediate package based on real-time temperature, monitoring value, maximum edge temperature, and warning temperature.

[0114] Using an infrared high-temperature thermometer, the first temperatures at the bottom of the tundish impact zone and the second temperatures of the tundish shell are collected. Trend parameters for the temperature at the bottom of the impact zone are determined based on the first temperatures, and the trend of the shell temperature (i.e., monitoring values) is determined based on the second temperatures. The maximum edge temperature and warning value are determined based on the molten steel phase line temperature and the safe pouring temperature. Finally, based on the real-time temperature at the bottom of the impact zone, the monitoring values, the maximum edge temperature, and the warning temperature, a tundish penetration warning is issued.

[0115] The method for determining and obtaining the first temperatures at the bottom of the intermediate package impact zone within a preset time period can be as follows: obtaining the first sub-temperatures at the bottom of the intermediate package impact zone within a first preset time period, and obtaining the second sub-temperatures at the bottom of the intermediate package impact zone within a second preset time period, wherein the first preset time period is earlier than the second preset time period.

[0116] For example, the first sub-temperature of the bottom of the intermediate pack impact zone can be obtained in the first hour, and the second sub-temperature of the bottom of the intermediate pack impact zone can be obtained in the second hour. It should be noted that the sampling frequency of the first sub-temperature and the second sub-temperature can be once per minute, once every five minutes, or once every ten minutes.

[0117] There are multiple ways to calculate trend parameters based on each first temperature. In one implementation method, such as... Figure 3 As shown, it includes the following steps:

[0118] Step 203-1: Determine the first mean value of each first sub-temperature.

[0119] Step 203-2: Determine the second mean value of each second sub-temperature.

[0120] Step 203-3: Determine the minimum temperature among the first sub-temperatures as the first target sub-temperature.

[0121] Step 203-4: Calculate the first difference between the first mean and the first target sub-temperature.

[0122] Step 203-5: Determine the maximum temperature among all the second sub-temperatures as the second target sub-temperature.

[0123] Step 203-6: Calculate the second difference between the second mean and the second target sub-temperature.

[0124] Step 203-7: Calculate the first ratio of the second difference to the first difference, as a trend parameter.

[0125] For example, the temperature data collected over 2 hours is statistically summarized to determine the trend parameter. The first sub-temperature T1 of the first hour is collected, the first mean of each T1 is determined, the smallest value among the T1 values ​​is determined as the first target sub-temperature, and the first difference between the first mean and the first target sub-temperature is calculated as the trend temperature difference t1. The difference between the second mean of each second sub-temperature T2 collected in the second hour and the maximum temperature among the T2 values ​​is calculated as the trend temperature difference t2. The first ratio of the second difference to the first difference is used as the trend parameter, i.e., t2 / t1 = v, where v is the trend parameter, t2 is the second difference, and t1 is the first difference.

[0126] There are multiple ways to obtain the second temperatures of the outer shell of the intermediate package within a preset time period. In one way, the second temperatures of any outer shell of the intermediate package within the preset time period are obtained, or the second temperatures of each outer shell of the intermediate package within the preset time period are obtained.

[0127] When obtaining the second temperature of any shell of the intermediate package, the second temperature of the first shell of the intermediate package, the second temperature of the second shell of the intermediate package, the second temperature of the third shell of the intermediate package, and the second temperature of the fourth shell of the intermediate package can be obtained. The first shell and the third shell are arranged in parallel, and the second shell and the fourth shell are arranged in parallel.

[0128] The second temperature of each of the four outer shells of the intermediate package is obtained, and the fifth sub-temperature group of each of the four sides of the intermediate package is obtained within the first preset time period; the fifth average value of each fifth sub-temperature group is determined as the second temperature of each outer shell of the intermediate package within the preset time period.

[0129] When obtaining the second temperatures of any outer shell of the intermediate package, there are multiple ways to calculate trend parameters based on each first temperature. In one implementation, such as... Figure 4 As shown, it includes the following steps:

[0130] Step 204-1: Obtain the third sub-temperature of any shell of the intermediate package of the first preset duration.

[0131] Step 204-2: Obtain the fourth sub-temperature of any shell of the intermediate package for the second preset duration.

[0132] Step 204-3: Determine the minimum temperature of each third sub-temperature.

[0133] Step 204-4: Determine the third mean of each third sub-temperature.

[0134] Step 204-5: Calculate the third difference between the third mean and the minimum temperature.

[0135] Step 204-6: Determine the maximum temperature of each fourth sub-temperature.

[0136] Step 204-7: Determine the fourth mean of each fourth sub-temperature.

[0137] Step 204-8: Calculate the fourth difference between the fourth mean and the maximum temperature.

[0138] Step 204-9: Calculate the second ratio of the fourth difference to the third difference.

[0139] Step 204-10: Calculate the product of the second ratio and the preset value, and use it as the monitoring value.

[0140] For example, the third average value of the third sub-temperature T3 collected in the first hour and the third difference between the minimum temperature of T3 are taken as the trend temperature difference t01, and the fourth average value of the temperature T4 collected in the second hour and the fourth difference between the maximum temperature of T4 are taken as the trend temperature difference t02. The monitoring value is calculated based on the following formula:

[0141] v2 = t02 / t01 × 0.8, where v2 is the monitored value, t02 is the fourth difference, t01 is the third difference, and 0.8 is the preset value.

[0142] It should be noted that since the outer shell is not directly impacted by the molten steel and is far from the center, its temperature is relatively low. Therefore, a temperature drop coefficient of 0.8 is set as the preset value. The preset value can be set to 0.9, 0.8, or 0.7, and this embodiment does not impose any specific limitations on this.

[0143] The process involves acquiring the second temperature of each of the four outer shells of the intermediate package, acquiring the fifth sub-temperature group of each of the four sides of the intermediate package within the first preset time period, determining the fifth mean of each of the fifth sub-temperature groups, acquiring the sixth sub-temperature group of each of the four sides of the intermediate package within the second preset time period, determining the sixth mean of each of the sixth sub-temperature groups, determining the minimum mean of each of the fifth mean, determining the seventh mean of each of the fifth mean, calculating the fifth difference between the seventh mean and the minimum mean, determining the maximum mean of each of the sixth mean, determining the eighth mean of each of the sixth mean, calculating the sixth difference between the eighth mean and the maximum mean, calculating the third ratio between the sixth difference and the fifth difference, and calculating the product of the third ratio and the preset value as the monitoring value.

[0144] There are multiple ways to determine the maximum edge temperature based on each first temperature, the trend parameter, and the upper limit value. In one implementation, such as... Figure 5 As shown, it includes the following steps:

[0145] Step 207-1: Calculate the difference between the molten steel phase line temperature and the safe pouring temperature as the upper limit.

[0146] Step 207-2: Calculate the mean of each first temperature.

[0147] Step 207-3: Calculate the first product of the upper limit value and the trend parameter.

[0148] Step 207-4: Calculate the first sum of the product of the mean of each first temperature and the first product.

[0149] Step 207-5: Calculate the second product of the second preset value and the trend parameter.

[0150] Step 207-6: Calculate the second sum of the second product and the first product as the maximum edge temperature.

[0151] The average of the first temperature collected in the first hour is taken as the initial temperature Tinitial of the impact zone, and the difference between the liquidus temperature of the molten steel in the tundish and the safe pouring temperature is taken as the upper limit.

[0152] The upper limit value can also be implemented by using the difference between the highest value of the liquidus temperature of the molten steel in the tundish and the highest value of the safe pouring temperature as the upper limit value.

[0153] S1 = S + 10v, S = T_initial + vL, S1 is the maximum edge temperature, T_initial is the average of all first temperatures, and L is the upper limit value.

[0154] >S1 is S2, and S2 is the warning temperature.

[0155] There are several ways to implement packet penetration warning for intermediate packets based on real-time temperature, monitored values, maximum edge temperature, and warning temperature. In one implementation method, such as... Figure 6 As shown, it includes the following steps:

[0156] Step 210-1: When the real-time temperature equals the maximum edge temperature, compare the real-time temperature with the warning temperature.

[0157] Step 210-2: When the real-time temperature equals the warning temperature, compare the trend parameter with the first value.

[0158] The first value is the product of the third preset value and the monitored value.

[0159] Step 210-3: When the trend parameter is greater than the first value, output the first prompt message.

[0160] Step 210-4: When the trend parameter is greater than the first value, compare the trend parameter with the second value.

[0161] The second value is the product of the fourth preset value and the monitored value, and the third preset value is less than the fourth preset value.

[0162] Step 210-5: If the trend parameter is greater than the second value, then it is determined that there is a risk of the bag being penetrated.

[0163] For example, when the real-time temperature reaches S1, the temperature of the tundish shell is monitored simultaneously with the temperature at the bottom of the tundish impact zone:

[0164] When the real-time temperature reaches the warning temperature S2, the trend parameter is compared with the monitoring value. If the trend parameter is greater than the first value (2v2), a yellow warning light is issued, which is the first prompt message, and monitoring continues.

[0165] It should be noted that 2v2 is the product of the third preset value and the monitoring value, and the third preset value can be set to 2.

[0166] If the trend parameter is greater than the second value, i.e., 3v2, it can be determined that the refractory material at the bottom of the impact zone of the tundish is severely corroded, posing a risk of tundish penetration. A red light will be activated, and an audible alarm will be triggered as a warning. It should be noted that 3v2 is the product of the fourth preset value and the monitoring value; the fourth preset value can be set to 3.
