Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] In the present invention, descriptions such as "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments may be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0024] An embodiment of the present invention provides a method for controlling the transfer of a molten iron ladle. Referring to Figure 1 as shown, the method includes the following steps S101 to S103:

[0025] S101: When the overhead crane transfers the first molten iron ladle and the first molten iron ladle is at a first preset position, obtain a plurality of first detected temperatures obtained by a plurality of infrared thermal imagers detecting the temperature of the outer shell of the first molten iron ladle.

[0026] It should be noted that if the temperature of the outer shell of the first molten iron ladle is detected only by a single infrared thermal imager, the temperature detection may be inaccurate, such as in the case where a single infrared thermal imager fails. Therefore, the embodiment of the present invention limits the temperature detection of the outer shell of the first molten iron ladle by a plurality of infrared thermal imagers, and then obtains the outer shell temperature of the first molten iron ladle based on a plurality of first detected temperatures, avoiding the occurrence of inaccurate temperature detection due to the failure of a single infrared thermal imager. Therefore, the detection accuracy of the outer shell temperature of the first molten iron ladle is improved.

[0027] In some embodiments, a plurality of infrared thermal imagers may include: a first group of infrared thermal imagers for detecting the bottom temperature of the first molten iron ladle shell; a second group of infrared thermal imagers for detecting the side wall temperature of the first molten iron ladle shell.

[0028] Specifically, the number of the first group of infrared thermal imagers may be one, and the number of the second group of infrared thermal imagers may be four. When the first molten iron ladle is in a first preset position, the first group of infrared thermal imagers is located in the area near the bottom of the first molten iron ladle, and the distance between the first group of infrared thermal imagers and the first molten iron ladle may be any distance between 5 meters and 30 meters. When the first molten iron ladle is in the first preset position, two of the second group of infrared thermal imagers may be located in the area near the first side wall of the first molten iron ladle, and the other two of the second group of infrared thermal imagers may be located in the area near the second side wall of the first molten iron ladle. The second side wall is opposite to the first side wall, and the distance between the second group of infrared thermal imagers and the first molten iron ladle may be any distance between 5 meters and 30 meters.

[0029] S102: Determine the shell temperature of the first molten iron ladle shell based on a plurality of first detected temperatures.

[0030] In some embodiments, step S102 may include: using the maximum detected temperature among the plurality of first detected temperatures as the shell temperature of the first molten iron ladle shell.

[0031] In other embodiments, step S102 may include: eliminating outliers from the plurality of first detected temperatures based on a preset reasonable temperature range to obtain a plurality of second detected temperatures; determining the shell temperature of the first molten iron ladle shell based on the plurality of second detected temperatures.

[0032] It should be noted that if the infrared thermal imager fails, the first detected temperature will be inaccurate data. In this case, determining the shell temperature based on the plurality of first detected temperatures is likely to result in inaccurate detection of the shell temperature. Therefore, the embodiments of the present invention define eliminating outliers from the plurality of first detected temperatures and then determining the shell temperature based on the plurality of second detected temperatures. Since the outliers are eliminated, it avoids inaccurate detection of the shell temperature due to the influence of incorrect data. Therefore, the accuracy of detecting the shell temperature of the first molten iron ladle shell is improved.

[0033] In some embodiments, determining the shell temperature of the first molten iron ladle shell based on the plurality of second detected temperatures may include: using the maximum detected temperature among the plurality of second detected temperatures as the shell temperature of the first molten iron ladle shell.

[0034] It should be noted that each of the multiple infrared thermal imagers is set at a different position. Therefore, each of the multiple second detected temperatures reflects the temperature of a different position on the outer shell of the first molten iron ladle. Also, since the heating conditions vary at different positions on the outer shell of the molten iron ladle, in the embodiments of the present invention, it is defined that the maximum detected temperature among the multiple second detected temperatures is used as the outer shell temperature of the first molten iron ladle, which can more timely detect the risk of penetration and leakage of the outer shell of the molten iron ladle, thus improving the transfer safety of the molten iron ladle.

[0035] In some other embodiments, based on the multiple second detected temperatures, determining the outer shell temperature of the first molten iron ladle may include: taking the average value of the multiple second detected temperatures as the outer shell temperature of the first molten iron ladle.

[0036] S103: If the outer shell temperature is greater than the preset temperature threshold, control the overhead crane to stop transferring the first molten iron ladle and output an alarm message.

[0037] It should be noted that the alarm message may be information for prompting the risk of molten iron overflow.

[0038] In some embodiments, before obtaining the multiple first detected temperatures obtained by the multiple infrared thermal imagers for temperature detection of the outer shell of the first molten iron ladle, it may further include: calibrating the multiple infrared thermal imagers.

[0039] It should be noted that due to on-site conditions, especially in the case of severe on-site dust, dust particles will absorb or scatter infrared radiation, resulting in an increase in temperature measurement error. Especially in long-distance measurements, this effect is more obvious because the interference of dust in the air on infrared radiation is greater during long-distance measurements. In addition, the infrared thermal imagers cannot be placed in ideal positions, and there are systematic biases in the temperatures detected by the infrared thermal imagers, which need to be corrected. Therefore, in the embodiments of the present invention, it is defined to calibrate the multiple infrared thermal imagers, thereby improving the accuracy of the temperatures detected by the infrared thermal imagers.

[0040] In some embodiments, calibrating the multiple infrared thermal imagers may include: sequentially taking each of the multiple infrared thermal imagers as the target infrared thermal imager; controlling the infrared pyrometer to be at the target position, where the target position is such that when the second molten iron ladle is at the second preset position, the coincidence degree of the laser spot of the infrared pyrometer with the target area of the outer shell of the second molten iron ladle is greater than the preset coincidence degree threshold; when the overhead crane transfers the second molten iron ladle and the second molten iron ladle is at the second preset position, controlling the infrared pyrometer to perform temperature detection on the target area of the outer shell of the second molten iron ladle to obtain the third detected temperature; and calibrating the target infrared thermal imager based on the third detected temperature.

[0041] It should be noted that when the overhead crane transfers the molten iron ladle, the molten iron ladle first passes through the second preset position and then passes through the first preset position. In addition, the target position can also make the angle deviation between the ray and the normal of the target area of ​​the second molten iron ladle shell less than a preset angle deviation threshold, the ray is determined according to the line connecting the infrared spot thermometer and the target area of ​​the second molten iron ladle shell, and the angle deviation threshold can be 0° to 10°.

[0042] It should be noted that, in the process of calibrating the target infrared thermal imager according to the third detection temperature of the infrared spot thermometer, the third detection temperature of the infrared spot thermometer needs to be used as the reference temperature to adjust the target infrared thermal imager so that the detection temperature of the target infrared thermal imager after adjustment is close to the third detection temperature of the infrared spot thermometer. Therefore, in order to ensure the temperature detection accuracy of the infrared spot thermometer, the embodiment of the present invention limits the position of the infrared spot thermometer by the target position to improve the temperature detection accuracy of the infrared spot thermometer, thereby achieving the beneficial effect of ensuring the calibration effectiveness of the infrared thermal imager.

[0043] In some embodiments, calibrating the target infrared thermal imager based on the third detection temperature may include: when the overhead crane transfers the second molten iron ladle and the second molten iron ladle is in a first preset position, controlling the target infrared thermal imager to perform temperature detection on a target area of ​​the outer shell of the second molten iron ladle to obtain a fourth detection temperature; and calibrating the target infrared thermal imager based on the fourth detection temperature and the third detection temperature.

[0044] In some embodiments, calibrating the target infrared thermal imager based on the fourth detection temperature and the third detection temperature can include: determining the temperature deviation between the fourth detection temperature and the third detection temperature; adjusting the emissivity of the target infrared thermal imager based on the temperature deviation between the fourth detection temperature and the third detection temperature so that the temperature deviation between the fifth detection temperature and the third detection temperature is less than a preset temperature deviation threshold, the fifth detection temperature being obtained by the target infrared thermal imager performing temperature detection on the target area of ​​the second molten iron ladle shell after adjusting the emissivity.

[0045] It should be noted that, in theory, a laboratory black body furnace can be used as a heat source to calibrate each fixed infrared thermal imager, but it is difficult to set up a black body furnace on the thermal imaging thermometer area several meters to more than ten meters above the ground, and adjust the angle so that it is aimed at each infrared thermal imager. The embodiment of the present invention directly uses the shell of the molten iron tank itself as a heat source, combines with the calibration measuring instrument, and formulates a certain operation process for calibration, which solves the problem that the on-site infrared thermal imager of the molten iron tank water shell temperature measuring device is difficult to calibrate.

[0046] refer to Figure 2 As shown, Figure 2Schematic diagram for calibrating multiple infrared thermal imagers in an embodiment of the present invention. Among them, a to e are infrared thermal imagers, f is an infrared spot thermometer, g is a computer, h is a switch, i is a server, and j is a ladle. The model of the infrared thermal imager can be STGT-1, the temperature measurement range can be -20 to 650 °C, and the accuracy is ±2% of the reading. The switch can be a 16-port switch H3CS5000-16X-EI, the server 3 can be an HP DL388G10 server, the infrared spot thermometer can be a T40-LT-70-SF2-0 infrared spot thermometer, the temperature measurement range of the infrared spot thermometer is -20 to 1000 °C, the accuracy is ±1%, and the distance-to-diameter ratio is 70:1. Each thermal imager is connected to the switch through an optical fiber, the switch is connected to the server through a network cable, and the infrared spot thermometer is connected to the computer through a USB communication cable. The server reads the temperature data of the ladle shell from the infrared thermal imager. The computer reads the spot temperature data of the ladle shell from the infrared spot thermometer.

[0047] The calibration process is illustrated by the following example: Step 1, calibrate the target area on the second ladle. On the ladle shell area covered by n thermal imagers, circular areas with diameters of d1, d2,... dn are selected as the target areas and marked. The diameter can be 115 mm. The areas are denoted as b1, b2,... bn respectively. Step 2, measure the temperature values of each area with the calibrated infrared spot thermometer. Keep the second ladle stationary, move the infrared spot thermometer to the appropriate positions respectively, aim at the temperature measurement blocks b1, b2,..., bn on the second ladle in sequence, and measure the temperature values TC1, TC2,... TCn of each block. When measuring, the positions of the infrared spot thermometer are determined as follows: the laser spot of the infrared spot thermometer is aligned with the center of the circular area, and the distance between the infrared spot thermometer and the target area is the diameter di (i = 1, 2,... n) of the area multiplied by the distance-to-diameter ratio of the infrared spot thermometer. The angle between the ray of the infrared spot thermometer aiming at the corresponding target area and the normal of the target area is controlled within the angle deviation threshold, and the infrared spot thermometer can be assisted in positioning by a laser rangefinder. Step 3, measure the temperature values of each target area with each thermal imager to be calibrated. Lift the second ladle to the thermal imaging measurement area (the first preset position), and n thermal imagers measure the average temperatures TU1, TU2,... TUn of the target areas b1, b2,..., bn respectively; Step 4, correct the temperature values of each thermal imager. Adjust the emissivity of each thermal imager so that the temperature value of the thermal imager in the corresponding area is TC1, TC2,... TCn.

[0048] In an embodiment of the present invention, when a crane transfers a first molten iron ladle and the first molten iron ladle is in a first preset position, a plurality of first detected temperatures obtained by a plurality of infrared thermal imagers detecting the temperature of the outer shell of the first molten iron ladle are acquired; based on the plurality of first detected temperatures, the outer shell temperature of the first molten iron ladle is determined; if the outer shell temperature is greater than a preset temperature threshold, the crane is controlled to stop transferring the first molten iron ladle, and an alarm message is output. By using a plurality of infrared thermal imagers to detect the temperature of the outer shell of the first molten iron ladle to determine the outer shell temperature of the first molten iron ladle, and since the outer shell temperature being greater than the preset temperature threshold indicates that there is a risk of penetration and leakage in the outer shell of the first molten iron ladle, at this time, the crane is controlled to stop transferring the first molten iron ladle, avoiding the transfer of the molten iron ladle when there is a risk of penetration and leakage in the outer shell of the first molten iron ladle, and at the same time avoiding the overflow of molten iron due to the penetration and leakage of the outer shell of the first molten iron ladle, minimizing the severity of the accident to the greatest extent. At the same time, an alarm message is output to prompt relevant personnel to take shelter and take corresponding measures in a timely manner, further reducing the severity of the accident. Therefore, the transfer safety of the molten iron ladle is improved.
