[0060] In the hot repair process of a ladle in a steel plant refining operation area, a ladle off-line needs to be subjected to a bottom blowing brick treatment. The bottom blowing brick of the ladle off-line is blocked by solidified molten steel, and an operator needs to hold a coal-oxygen gun to perform burning. The burning state is as shown in the figure. Figure 6As shown, the process removes the attached solidified molten iron while minimizing damage to the bottom-blown brick, reducing material and energy consumption. Traditionally, argon gas is externally supplied to the bottom-blown brick, and workers visually inspect it to determine if any defects are present. Figure 7 The black box shown (ventilation area) is used to make simple judgments based on auxiliary flow data, but the judgment error is relatively large, and the technology is relatively outdated.

[0061] In view of this, this application provides a bottom-blown brick processing system, please refer to... Figure 1 , Figure 1 This is a wireframe diagram of the bottom-blown brick processing system in an embodiment of this application, such as... Figure 1 As shown, the bottom-blown brick processing system 100 provided in this application embodiment includes:

[0062] Argon source 101;

[0063] The first branch pipeline 102 has an inlet connected to the argon source 101 and an outlet connected to the first bottom blow hole of the ladle 107. The first bottom blow brick to be processed is placed inside the ladle 107 and corresponds to the position of the first bottom blow hole.

[0064] The first gas mass flow controller 103 is installed in the first branch pipeline 102;

[0065] The first pressure sensor 104 is installed in the first branch pipeline 102;

[0066] The first solenoid valve 105 is installed in the first branch pipeline 102;

[0067] The controller 106 is electrically connected to the first gas mass flow controller 103, the first pressure sensor 104, and the first solenoid valve 105, respectively.

[0068] The bottom-blown brick processing system 100 provided in this application embodiment controls the process of hot repairing the bottom-blown bricks in the ladle 107 as follows: Figure 2 As shown, argon gas from argon source 101 is introduced into ladle 107 through first branch pipeline 102. Controller 106 controls the opening of first gas mass flow controller 103 to adjust the argon flow rate in first branch pipeline 102. Controller 106 simultaneously receives the actual flow rate of argon gas through first branch pipeline 102 from first gas mass flow controller 103. Controller 106 also receives the actual pressure value of argon gas through first branch pipeline 102 sent by first pressure sensor 104. Based on the ratio of actual pressure value to actual flow rate value, controller 106 determines whether the bottom-blown brick is qualified and whether there is a leak in the bottom-blown brick processing system 100, thereby achieving rapid identification of bottom-blown brick hot repair results and accelerating bottom-blown brick hot repair efficiency.

[0069] The controller 106 can adopt a PLC to complete direct control of system pressure flow and state recording, for example, a S7-200 smart programmable controller 106 of Siemens, Germany, as the control core.

[0070] In some optional embodiments, as shown in the figure, the bottom blowing brick treatment system 100 further comprises: Figure 2

[0071] The second branch pipeline 201 is connected with the argon source 101 at the inlet and connected with the second bottom blowing hole of the ladle 107 at the outlet, and the second bottom blowing brick to be treated is arranged in the ladle 107 and corresponds to the position of the second bottom blowing hole;

[0072] The second gas mass flow controller 202 is arranged in the second branch pipeline 201.

[0073] The second pressure sensor 203 is arranged in the second branch pipeline 201.

[0074] The second electromagnetic valve 204 is arranged in the second branch pipeline 201.

[0075] The controller 106 is electrically connected with the second gas mass flow controller 202, the second pressure sensor 203 and the second electromagnetic valve 204 respectively.

[0076] The ladle 107 is usually provided with two bottom blowing bricks, and the first branch pipeline 102 and the second branch pipeline 201 correspond to the two bottom blowing bricks respectively. In the process of hot repair of the bottom blowing bricks in the ladle 107, the two bottom blowing bricks can be simultaneously hot repaired, and the two bottom blowing bricks can also be alternately hot repaired.

[0077] Exemplarily, the determination process of hot repair of the two bottom blowing bricks of the ladle 107 is as shown in the figure. Figure 3 As shown in the figure, the operator uses a hot gun to heat the bottom blowing bricks in the ladle 107, triggers an operation start signal on site, and makes the two branch pipelines (the first branch pipeline 102 and the second branch pipeline 201) ventilate and pressurize, and identifies single-brick operation or double-brick operation. When the single-brick operation is performed, the controller 106 controls the first gas mass flow controller 103 to perform multiple opening degree circulation actions, and simultaneously performs flow and pressure acquisition, and judges whether the opening degree flow pressure wheel tour meets the model condition. When the double-brick operation is performed, the controller 106 controls the first gas mass flow controller 103 and the second gas mass flow controller 202 to perform multiple opening degree circulation actions respectively, and simultaneously performs flow and pressure acquisition, and judges whether the opening degree flow pressure wheel tour meets the model condition. The model condition specifically refers to a pressure flow relationship curve.

[0078] ​The flow pressure curve of different bottom blowing bricks is different, which will lead to the matching accuracy of the data model in the hot repair process of part of the bottom blowing bricks, and the distortion of the other part, resulting in judgment error. Therefore, batch experiments of commonly used bottom blowing bricks are needed to obtain accurate data.

[0079] In order to obtain good measurement and control effect and accurately adjust the opening of argon, the opening of the first gas mass flow controller 103 or the second gas mass flow controller 202 is increased or decreased in the multi-opening cycle operation process. The preset data model is used. Specifically, according to the type of the bottom blowing brick, the corresponding data model, i.e. the pressure-flow relationship curve, is matched.

[0080] Exemplarily, for the pressure-flow relationship of the plate-type gas distribution brick, the specific relationship between pressure and flow is shown in the following table:

[0081]

[0082]

[0083] For the plate-type gas distribution brick, the pressure-flow relationship curve as shown in Figure 4 can be obtained based on the above table. Based on the judgment logic as shown in Figure 3 , the controller 106 compares the actual flow value and the actual pressure value received. If the actual pressure value is consistent with the pressure-flow relationship curve as shown in Figure 4 under the condition of the same flow, it is determined that the bottom blowing brick is qualified, and the gas mass flow controller 106 of the corresponding branch can be closed.

[0084] If the actual pressure value is continuously higher than the pressure-flow relationship curve as shown in Figure 4 under the condition of the same flow, it is determined that the bottom blowing brick is blocked.

[0085] If the actual pressure value is continuously lower than the pressure-flow relationship curve as shown in Figure 4 under the condition of the same flow, it is determined that the bottom blowing brick treatment system 100 leaks, and the gas mass flow controller 106 of the corresponding branch needs to be closed to check the leakage point.

[0086] It can be understood that in the use process, the connection of the pipe joint part of the bottom blowing brick treatment system 100 may occasionally leak slightly. The loose connection will lead to low pressure under the condition of the same flow of the system, distortion of the pressure holding link in the early stage of the system, and further lead to misjudgment of the leakage or reaching the qualified state in advance.

[0087] To solve the above problems, the pipe joint can be replaced with a special quick connector, which can prevent the leakage of the pipe joint part and improve the operation efficiency of the pipe joint. The above problems are solved.

[0088] Exemplarily, for the diffused gas permeable brick, the specific pressure and flow rate relationship is shown in the following table:

[0089] Pressure (Mpa) Flow (m 3 / h) Flow (L / min) 0.1 10 166.7 0.2 16 266.7 0.3 18 316.7 0.4 20 283.3 0.5 22 366.7 0.6 24 400 0.7 27 450

[0090] For the diffused gas permeable brick, based on the above table, a pressure flow rate relationship curve as shown in Figure 5 may be obtained, based on the judgment logic as shown in Figure 3 , the controller 106 compares the received actual flow rate value and actual pressure value, if under the same flow rate condition, the actual pressure value is consistent with the pressure flow rate relationship curve as shown in Figure 5 , it is determined to be qualified, and the gas mass flow controller 106 of the corresponding branch can be closed. If under the same flow rate condition, the actual pressure value is continuously higher than the pressure flow rate relationship curve as shown in Figure 5 , it is determined to be blocked. If under the same flow rate condition, the actual pressure value is continuously lower than the pressure flow rate relationship curve as shown in Figure 5 , it is determined to be gas leakage, and the gas mass flow controller 106 of the corresponding branch needs to be closed to check the gas leakage point.

[0091] It can be understood that, in combination with experienced hot repair teachers, the key points of naked eye identification of abnormalities are discussed, researched and analyzed, and the visual recognition technology is deeply applied. Additional logical judgment conditions are added to the determination of the result at the end of the bottom blowing brick. By collecting and identifying the profile and heat distribution of the bottom blowing brick inside the ladle 107, the key data are compared, and the enablement is sent if the conditions are met, otherwise the hot repair personnel are reminded to confirm the abnormality. As shown in Figure 6 , it is the actual state of the bottom blowing brick of the ladle 107 hot repair.

[0092] The above embodiment can realize the result determination method of constructing a determination data model through gas flow rate, pressure and bottom blowing brick model. The fault self-diagnosis of whether the pipeline leaks is determined through flow rate, pressure and bottom blowing brick model. The argon and coal gas medium are intelligently opened and closed through the model, so as to achieve the purpose of energy medium saving.
