[0044] First, the terms involved in this application are explained:

[0045] A torpedo ladle is a torpedo-shaped molten iron ladle with a relatively long transverse length used in large blast furnaces, also known as a torpedo car. It includes a speed reducer, a support shaft of the torpedo ladle, and a bearing seat. The support shaft of the torpedo ladle is supported by the bearing seat. The output shaft of the speed reducer is coaxially connected to the support shaft of the torpedo ladle, which can be a coaxial rigid fixed connection or a coaxial flexible connection. As an indispensable molten iron transportation and storage device in modern metallurgy industry, it plays an important role in metallurgical enterprises.

[0046] With the development of technology, certain progress has been made in the monitoring technology for the erosion of refractories in torpedo ladles. The inventors found that existing detection methods such as the weighing method, the cold inspection method, and the instrument spot inspection method all have limitations. For example, the weighing method cannot accurately reflect the situation of uneven erosion.

[0047] Based on the above technical problems, in some embodiments of this application, a temperature detection layer is provided between the inner wall of the steel shell of the torpedo ladle and the refractory coating to collect multiple temperature values at different positions on the inner wall of the steel shell of the torpedo ladle, and based on the correlation between the inner wall temperature and the thickness of the refractory coating, the erosion thickness of the refractory coating corresponding to each temperature value is determined. When the erosion thickness of any refractory coating is greater than a preset thickness threshold, a safety reminder message is sent. In this application, multiple temperature sensing strips in the temperature detection layer are arranged in parallel with each other on the inner wall of the steel shell, realizing the comprehensive monitoring of the temperature on the inner wall of the steel shell of the torpedo ladle. At the same time, since the refractory coating at the liquid level is more vulnerable to erosion than the refractory coating at other positions, each temperature sensing strip is parallel to the liquid level of the liquid contained in the torpedo ladle. The greater the erosion thickness of the refractory coating, the higher the corresponding temperature value collected, making it easier to detect the erosion situation in the refractory coating and effectively reducing the leakage risk of the torpedo ladle.

[0048] Next, specific embodiments are used to elaborate in detail on the technical solutions of this application and how the technical solutions of this application solve the above technical problems. These specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below in conjunction with the drawings.

[0049] In the embodiments of this application, a safety monitoring method for a torpedo ladle is provided, which can be applied to a torpedo ladle. The tank body of the torpedo ladle includes a steel shell, a temperature monitoring layer, and a refractory coating; the temperature detection layer is arranged between the inner wall of the steel shell and the refractory coating; the temperature detection layer includes multiple temperature sensing strips, and the multiple temperature sensing strips are arranged on the inner wall of the steel shell. Each temperature sensing strip is parallel to each other, and each temperature sensing strip is parallel to the liquid level of the liquid contained in the torpedo ladle. As Figure 1 shown, the method includes:

[0050] S101. Based on the preset acquisition frequency, collect the temperature values of the inner wall of the steel shell based on each temperature sensing strip.

[0051] Specifically, within the preset acquisition time period, such as within one day, collect the temperature according to the preset acquisition frequency through each temperature sensing strip to obtain the temperature values at multiple locations on the inner wall of the steel shell.

[0052] S102. Obtain the correlation between the inner wall temperature of the steel shell and the thickness of the refractory coating.

[0053] Among them, the above correlation can be preset and constructed by linear fitting. Specifically, multiple historical inner wall temperatures and the historical coating erosion thickness corresponding to each historical inner wall temperature can be obtained in advance, and then linear fitting is performed based on the above multiple historical inner wall temperatures and the historical coating erosion thickness corresponding to each historical inner wall temperature to obtain the corresponding fitting function, and this fitting function is used as the above correlation.

[0054] S103. Based on the correlation, determine the refractory coating erosion thickness corresponding to each temperature value.

[0055] Specifically, each collected temperature value can be substituted into the above fitting function to obtain the refractory coating erosion thickness corresponding to each temperature value.

[0056] S104. When any refractory coating erosion thickness is greater than the preset thickness threshold, send a safety reminder message.

[0057] Among them, the above preset thickness threshold can be half of the initial thickness of the refractory coating.

[0058] Specifically, when any refractory coating erosion thickness is greater than the preset thickness threshold, it indicates that the refractory coating is eroded too much and the steel shell has a risk of high-temperature softening. In order to avoid the leakage of the liquid contained in the torpedo ladle, a safety reminder message can be sent so that the user can timely perform targeted repairs on the corresponding parts of the inner wall of the steel shell.

[0059] In the embodiment of the present application, a temperature detection layer is arranged between the inner wall of the steel shell of the torpedo ladle and the refractory coating to collect multiple temperature values at different positions on the inner wall of the steel shell of the torpedo ladle, and the erosion thickness of the refractory coating corresponding to each temperature value is determined based on the correlation between the inner wall temperature and the refractory coating thickness. When the erosion thickness of any refractory coating is greater than the preset thickness threshold, a safety reminder message is sent. In the present application, multiple temperature sensing strips of the temperature detection layer are arranged in parallel with each other on the inner wall of the steel shell, realizing comprehensive monitoring of the temperature on the inner wall of the steel shell of the torpedo ladle. At the same time, since the refractory coating at the liquid level is more vulnerable to erosion than the refractory coating at other positions, each temperature sensing strip is parallel to the liquid level of the liquid contained in the torpedo ladle. The greater the erosion thickness of the refractory coating, the higher the corresponding collected temperature value, making it easier to detect the erosion situation in the refractory coating and effectively reducing the leakage risk of the torpedo ladle.

[0060] In a possible implementation provided in the embodiment of the present application, after collecting the temperature value of the inner wall of the steel shell based on each temperature sensing strip, the above method further includes:

[0061] Obtain the current time information, associate and store the current time information with each temperature value, and display the temperature value on a preset display screen.

[0062] Specifically, the torpedo ladle is connected to a preset visualization terminal. After obtaining the current time information, the torpedo ladle can associate and store the current time information with each temperature value and send the temperature value to the visualization terminal so that the temperature value can be displayed on the display screen of the visualization terminal. Users can monitor the erosion state of the refractory coating of the torpedo ladle in real time according to the displayed numerical value on the display screen, enhancing the user experience.

[0063] In a possible implementation provided in the embodiment of the present application, each temperature value corresponds to a label information, and the label information is used to indicate the temperature sensing strip corresponding to the temperature value.

[0064] In the embodiment of the present application, each temperature value can correspond to a label information, and the label information is used to indicate the temperature sensing strip corresponding to the temperature value. Since the distribution positions of each temperature sensing strip are fixed, the erosion situation of the refractory coating at different parts of the inner wall of the steel shell can be determined based on the temperature value. When the temperature value is too high, it indicates that the refractory coating at the corresponding position is eroded too much, posing a safety risk, laying a good foundation for subsequent safety warning.

[0065] In a possible implementation provided in the embodiment of the present application, after collecting the temperature value of the inner wall of the steel shell based on each temperature sensing strip, the above method further includes:

[0066] When any temperature value is greater than the preset temperature threshold, a safety warning message is sent.

[0067] In an embodiment of the present application, a possible implementation is provided, and the above temperature threshold is 300 °C.

[0068] In an embodiment of the present application, a possible implementation is provided, and the liquid contained in the torpedo ladle includes hot metal.

[0069] In an embodiment of the present application, when the liquid contained in the torpedo ladle is hot metal, a separation phenomenon of hot metal and slag will occur at the liquid level of the hot metal. Then, the erosion rate of the refractory coating at the liquid level, that is, the slag-iron interface, is relatively faster than that of the refractory coating at other positions on the inner wall. Therefore, laying the temperature sensing strip parallel to the slag-iron interface can ensure full coverage of the easily eroded parts of the refractory coating and enhance the accuracy of safety monitoring of the torpedo ladle.

[0070] In an embodiment of the present application, a possible implementation is provided, and the above temperature sensing strip is a thermal sensitive cable, and the temperature measurement range of the thermal sensitive cable is 30 °C - 600 °C.

[0071] In an embodiment of the present application, the temperature of different positions on the inner wall of the torpedo ladle can be collected through the thermal sensitive cable to obtain the temperature changes of each part of the refractory coating, so as to analyze the erosion state of the refractory coating, realize the automatic detection and early warning of the erosion of the refractory coating of the torpedo ladle, improve the safety detection efficiency of the torpedo ladle, and enhance the user experience.

[0072] To better understand the above safety monitoring method of the torpedo ladle, the following combines Figures 2 - 4 A detailed example of the safety monitoring method of the torpedo ladle of the present application is elaborated.

The method includes the following steps:

[0073] S201, obtain the temperature values collected by each thermal sensitive cable through the temperature monitor, and transmit the temperature values back to the data analysis terminal, and the data analysis terminal sends each temperature value to the client for visual display.

[0074] As Figure 2 shown, it is a side view of the torpedo ladle. Each thermal sensitive cable is arranged on the inner wall of the steel shell 204. The first thermal sensitive cable 201, the second thermal sensitive cable 202, and the third thermal sensitive cable 203 are externally connected to the first temperature detector 205. As Figure 3As shown, it is a cross-sectional view of a torpedo ladle.

[0075] S202, the data analysis terminal obtains the correlation between the inner wall temperature of the steel shell and the thickness of the refractory coating, and based on the correlation, determines the erosion thickness of the refractory coating corresponding to each temperature value.

[0076] S203, when the erosion thickness of any refractory coating is greater than the preset thickness threshold, the data analysis terminal sends a reminder instruction to the client, and the client issues a safety reminder message. When any temperature value is greater than 300 °C, the data analysis terminal sends a warning instruction to the client, and the client issues a safety warning message.
