[0001] The present invention relates to the field of tundish temperature detection, and in particular to a tundish temperature early warning method, device, equipment, and readable storage medium. Background Art

[0002] Currently, tundish temperature monitoring primarily relies on temperature guns, making it impossible to measure the temperature in the narrow area where the tundish is located. For example, in a 10-machine, 10-stream continuous casting machine with two connected tundish impactors, the area between the two tundishes is too small to measure with a temperature gun, making it very prone to breakouts. Consequently, existing technology is unable to measure the narrow area (impact zone) where the tundish is located. Consequently, when the temperature in the impact zone is too high, a timely warning cannot be issued, significantly increasing the frequency of breakouts. Summary of the Invention

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0040] Please refer to Figure 1 , Figure 1 This is a flow chart of a tundish temperature early warning method provided by an embodiment of the present invention. The method may include:

[0041] S100, obtaining temperature data of the impact zone of the tundish collected by a temperature measuring thermal resistor transmitter; wherein the temperature measuring thermal resistor transmitter is a temperature measuring device arranged in the impact zone of the tundish.

[0042] The temperature-measuring RTD transmitter in this embodiment consists of a reference unit, an R / V conversion unit, a linear circuit, reverse polarity protection, current limiting protection, and a V / I conversion unit. After the RTD signal is converted and amplified, a linear circuit compensates for the nonlinear relationship between temperature and resistance. After passing through the V / I conversion circuit, a constant current signal of 4-20 mA is output that is linearly related to the measured temperature. This embodiment uses the RTD transmitter to obtain temperature data from the tundish impact zone. This embodiment does not limit the specific type of temperature data. For example, the temperature data can be a specific temperature value or the rate of temperature rise. This embodiment does not limit the specific location of the tundish impact zone; the data only need to be located at the tundish impact zone. For example, the tundish impact zone can be the junction of the two tundishes in a 10-machine, 10-stream continuous casting machine; or the bottom of the tundish in a 6-machine, 6-stream continuous casting machine; or the junction and bottom of the two tundishes in a 10-machine, 10-stream continuous casting machine. The temperature-measuring RTD transmitter in this embodiment is located in the tundish impact zone. This embodiment does not limit the specific installation method of the temperature measuring thermal resistor transmitter in the tundish impact zone. For example, the temperature measuring thermal resistor transmitter can be drilled and installed in the tundish impact zone, or the temperature measuring thermal resistor transmitter can be clipped into the tundish impact zone.

[0043] S101, obtaining a preset warning temperature threshold.

[0044] This embodiment does not limit the specific value of the preset warning temperature threshold, as long as it can detect that the temperature in the impact zone of the tundish is too high. For example, the preset warning temperature threshold may be 320°C, 321°C, or 322°C.

[0045] S102: Compare the temperature data with a preset warning temperature threshold, and issue a warning when it is determined that the temperature data exceeds the preset warning temperature threshold.

[0046] This embodiment compares the temperature data collected by a temperature-measuring resistance thermometer (RTM) in the impact zone of the tundish with a preset warning temperature threshold. If the temperature data exceeds the preset warning temperature threshold, an early warning is issued. This embodiment does not limit the specific actions performed when the temperature data does not exceed the preset warning temperature threshold. For example, if the temperature data does not exceed the preset temperature threshold, no display is displayed. Alternatively, if the temperature data does not exceed the preset temperature threshold, a normal prompt message is displayed.

[0047] Furthermore, in order to fully obtain the temperature of the impact zone of the tundish, the temperature data of the impact zone of the tundish collected by the temperature measuring resistance thermometer may include:

[0048] The temperature data of the impact zone of the tundish collected by the temperature measuring thermal resistance transmitter is obtained; wherein the temperature measuring thermal resistance transmitter is installed at the joint of the two tundishes and the bottom of the two tundishes.

[0049] In this embodiment, the temperature-measuring RTD transmitters are installed at the two intermediate joints and at the bottoms of the two tundishes. By designating the area with the smallest separation between the tundishes—the joints and the bottoms—as the intermediate impact zone, and installing the RTD transmitters there, this embodiment provides more comprehensive and robust temperature data, thereby enabling comprehensive monitoring of the non-impact zone. This embodiment does not limit the specific number of RTD transmitters. For example, six, ten, or even twelve RTD transmitters may be used.

[0050] Furthermore, in order to reduce the impact caused by excessive temperature, when it is determined that the temperature data exceeds the preset warning temperature threshold, issuing a warning may include:

[0051] When it is determined that the temperature data exceeds the preset warning temperature threshold and the duration exceeds the preset time threshold, an early warning is issued and casting is stopped.

[0052] In order to reduce the impact of excessive temperature, this embodiment determines that when the temperature data exceeds the preset warning temperature threshold and the duration exceeds the preset time threshold, an early warning is issued and casting is stopped, thereby reducing the temperature of the tundish from being continuously too high. This embodiment does not limit the specific value of the early warning temperature threshold. For example, the preset early warning temperature threshold can be 320°C, or the preset early warning temperature threshold can be 321°C, or the preset early warning temperature threshold can also be 322°C. This embodiment does not limit the specific data of the preset time threshold. For example, the preset time threshold can be 4 minutes, or the preset time threshold can be 5 minutes, or the preset time threshold can be 8 minutes.

[0053] Furthermore, in order to replace the tundish in a timely manner, the tundish temperature detection method may further include:

[0054] After casting is completed, the damage degree of the impact zone of the tundish is detected based on the temperature data;

[0055] When the damage level reaches the preset replacement state, replace the tundish.

[0056] This embodiment does not limit the specific state of the preset tundish replacement state. For example, the preset replacement state may be when the tundish is very thin or when a hole is present. After casting is completed, when temperature data reaches the warning temperature, this embodiment detects the extent of damage to the impact zone of the tundish based on the temperature data. If the damage reaches the preset replacement state, the tundish is replaced, thereby ensuring timely replacement.

[0057] Furthermore, in order to monitor the status of the tundish in real time, the above-mentioned acquisition of the temperature data of the impact zone of the tundish collected by the temperature measuring resistance thermometer may include:

[0058] The temperature data of the impact zone of the tundish is acquired in real time by the temperature measuring resistance thermometer.

[0059] In order to realize real-time monitoring of the temperature of the impact zone of the tundish, this embodiment obtains the temperature data of the impact zone of the tundish collected by the temperature measuring resistance thermometer in real time.

[0060] Furthermore, in order to obtain the temperature of the non-impact zone of the tundish, the tundish detection method may further include:

[0061] Obtaining temperature data of the non-impact area corresponding to the non-impact area of ​​the tundish collected by an infrared thermal imager, wherein the infrared thermal imager is placed around the tundish;

[0062] Determine whether to issue a non-impact area warning based on the temperature data of the non-impact area.

[0063] In this embodiment, an infrared thermal imager collects temperature data corresponding to the non-impact area of ​​the tundish. The non-impact area of ​​the tundish in this embodiment refers to locations other than the impact area of ​​the tundish. For example, the non-impact area of ​​the tundish can be the outer area of ​​a single tundish (excluding the bottom of the single tundish), or the non-impact area of ​​the tundish can be the outer area of ​​a double tundish (excluding the junction of the double tundish and the bottom of the double tundish). The infrared thermal imager in this embodiment is placed around the tundish. An infrared thermal imager is a device that uses infrared thermal imaging technology to detect infrared radiation from a target object and converts an image of the target object's temperature distribution into a visual image by performing signal processing, photoelectric conversion, and other means. The infrared thermal imager accurately quantifies the actual heat detected and creates a real-time image of the entire target object in the form of a surface, thereby accurately identifying suspected fault areas that are heating. The operator uses the image color and hotspot tracking display function displayed on the screen to preliminarily determine the heating situation and fault location, and conducts rigorous analysis, thereby demonstrating high efficiency and high accuracy in confirming the problem.

[0064] Furthermore, in order to prevent the non-shock zone temperature of the tundish from being too high, the above-mentioned determination of whether to issue a non-shock zone warning based on the non-shock zone temperature data includes:

[0065] When the temperature data of the non-impact area exceeds the preset rising speed threshold, a non-impact area warning is issued; wherein the temperature data of the non-impact area is the temperature rising speed.

[0066] This embodiment performs a non-shock zone warning when determining that the non-shock zone temperature data exceeds a preset temperature increase rate threshold. This embodiment determines whether to perform a non-shock zone warning by comparing the collected non-shock zone temperature data with a preset temperature increase rate threshold.

[0067] In order to make the present invention easier to understand, please refer to Figure 2 , Figure 2 The flowchart of the tundish temperature early warning method provided by the embodiment of the present invention may specifically include:

[0068] The tundish temperature early warning method monitors the non-impact zone temperature data of the entire double tundish outer area corresponding to the tundish of the 10-machine 10-stream continuous casting machine collected by the red hot external imager, and obtains the impact zone temperature data of the double tundish junction and the impact zone corresponding to the tundish bottom of the double tundish of the 10-machine 10-stream continuous casting machine collected by the temperature measuring resistance transmitter. The installation position of the red hot external imager in this embodiment is as follows: Figure 3 As shown, Figure 3The embodiment of the present invention provides an online monitoring layout diagram of the non-impact area of ​​a double tundish. Two red-hot external imagers are installed on the pillars on both sides of the south side of the rotary field to cover the south side and both end areas of the two tundishes. A red-hot external imager is installed on each tundish car at the casting position to monitor the north side of the tundish wall. Six fixed red-hot external imagers collect temperature data of the non-impact area of ​​the corresponding area. The installation position of the temperature measuring resistance thermometer in this embodiment is as follows: Figure 4 As shown, Figure 4 This is a schematic diagram of a pre-embedded fixed-point temperature measurement RTD transmitter provided by an embodiment of the present invention. Six RTD transmitters are drilled and installed for each tundish at the junction of two tundish cars and at the bottom of the tundish. The system then obtains temperature data from the non-impact zone and determines whether it exceeds 350°C and whether the rate of temperature increase exceeds 40°C / h. If the non-impact zone temperature exceeds 350°C or 40°C / h, a warning is issued; otherwise, monitoring continues. The system also simultaneously obtains temperature data from the impact zone to determine whether it exceeds 320°C. If the impact zone temperature exceeds 320°C, a determination is made as to whether the duration exceeds 5 minutes. If the impact zone temperature is at 320°C and the duration exceeds 5 minutes, a warning is issued and casting is stopped. If only the temperature exceeds 320°C, an alarm is confirmed.

[0069] The tundish temperature early warning method provided in an embodiment of the present invention is applied to obtain temperature data of the tundish impact zone collected by a temperature measuring resistance thermometer transmitter; wherein the temperature measuring resistance thermometer transmitter is a temperature measuring device installed in the tundish impact zone; obtain a preset early warning temperature threshold; compare the temperature data with the preset early warning temperature threshold, and issue an early warning when it is determined that the temperature data exceeds the preset early warning temperature threshold. The present invention obtains temperature data of the tundish impact zone by using a temperature measuring resistance thermometer transmitter installed in the tundish, and then determines whether to issue an early warning based on the preset early warning temperature threshold and the temperature data. The present invention can obtain the temperature of the tundish impact zone through the temperature measuring resistance thermometer, so that the temperature of the tundish impact zone can be detected, thereby achieving an early warning of the temperature of the tundish impact zone. In addition, the embodiment of the present invention installs the temperature measuring resistance thermometer transmitter at the joint of the two ladles and at the bottom of the two ladles, so that the collected temperature of the non-impact zone of the tundish is more comprehensive, thereby realizing comprehensive detection of the non-impact zone of the tundish; and, when the temperature data exceeds the preset threshold and the duration reaches the preset time threshold, the embodiment of the present invention will issue an early warning and stop casting, thereby reducing damage to the tundish; and, the embodiment of the present invention will promptly detect and replace the tundish after the casting is completed; and, the embodiment of the present invention can collect the temperature of the impact zone of the tundish in real time, thereby realizing real-time monitoring of the temperature of the impact zone of the tundish; and, the non-impact zone temperature data corresponding to the non-impact zone of the tundish collected by the infrared thermal imager can be obtained, thereby realizing early warning of the non-impact zone.
