[0042] During the process of charging molten iron into a ladle, there are often situations where the molten iron overflows and damages or burns out the rail scale, resulting in inaccurate measurement of the molten iron charging amount, thereby affecting the control accuracy of the molten iron charging amount in the ladle. For this reason, the embodiments of the present disclosure provide a molten iron charging amount control method, device, system, equipment, and medium, which can effectively solve this problem. The molten iron charging amount control method, device, system, equipment, and medium provided by the embodiments of the present disclosure will be further described in detail below.

[0043] Figure 1 It is a flowchart of a molten iron charging amount control method provided by an embodiment of the present disclosure. This embodiment is applicable to the situation of automatically controlling the molten iron charging amount in a ladle. This method can be executed by a molten iron charging amount control device, which can be implemented in the form of hardware and / or software, and the molten iron charging amount control device can be configured in electronic devices such as terminals and servers. As Figure 1As shown, the method includes:

[0044] S110. Obtain the cross-sectional area of the molten iron in the runner, the flow velocity of the molten iron in the runner, and the duration of filling the ladle with molten iron.

[0045] Herein, the runner is a device that collects the molten iron in the blast furnace and transports it to the ladle, and can also be referred to as the iron runner. Exemplarily, Figure 2 is a schematic diagram of molten iron supply provided according to an embodiment of the present disclosure; 1 represents the blast furnace, 2 represents the runner, and 3 represents the ladle. The cross-sectional area refers to the instantaneous cross-sectional area of the flowing molten iron in the runner, which can be measured and / or calculated by an electronic device, and is not specifically limited herein. The flow velocity refers to the instantaneous flow velocity of the molten iron in the runner, which can be measured and / or calculated by an electronic device, and is not specifically limited herein. The duration refers to the time length of filling the ladle with molten iron, which can be measured and / or calculated by an electronic device, and is not specifically limited herein.

[0046] S120. Determine the filling weight of the molten iron in the ladle based on the cross-sectional area of the molten iron in the runner, the flow velocity of the molten iron in the runner, and the duration of filling the ladle with molten iron.

[0047] Herein, the filling weight refers to the weight of the molten iron filled into the ladle.

[0048] Specifically, the volume of the molten iron filled into the ladle can be calculated according to the cross-sectional area of the molten iron in the runner, the flow velocity of the molten iron in the runner, and the duration of filling the ladle with molten iron, and then the filling weight of the molten iron in the ladle can be calculated based on the volume of the molten iron filled into the ladle.

[0049] It should be noted that through the cross-sectional area of the molten iron, the flow velocity of the molten iron, and the filling duration, the accurate calculation of the filling weight of the molten iron in the ladle is realized. This method does not need to worry about the situation of molten iron overflowing and burning out the rail scale, and effectively improves the accuracy of the filling weight of the molten iron in the ladle.

[0050] S130. When the filling weight of the molten iron in the ladle meets the molten iron filling stop condition, send a signal for the molten iron launder to flip, so that the molten iron launder flips.

[0051] Herein, the molten iron filling stop condition refers to the judgment condition for whether to stop filling the ladle with molten iron, which can be a single threshold judgment condition or a range interval judgment condition, etc., and is not specifically limited herein. Preferably, the molten iron filling stop condition may include that the filling weight of the molten iron in the ladle reaches a preset weight threshold.

[0052] Exemplarily, the preset weight threshold may be W1, and the charged weight of the molten iron in the ladle may be W. When W reaches W1, that is, when W = W1, the electronic device may send a signal to flip the molten iron launder, so that the molten iron launder flips, and the molten iron launder stops charging the current ladle with molten iron, and the molten iron flows into other ladles.

[0053] In the technical solution of the embodiment of the present disclosure, by obtaining the cross-sectional area of the molten iron in the runner, the flow velocity of the molten iron in the runner, and the duration of charging the ladle with molten iron, and then determining the charged weight of the molten iron in the ladle based on the cross-sectional area of the molten iron in the runner, the flow velocity of the molten iron in the runner, and the duration of charging the ladle with molten iron; when the charged weight of the molten iron in the ladle meets the condition for stopping charging the molten iron, a signal to flip the molten iron launder is sent, so that the molten iron launder flips. In the above technical solution, through the cross-sectional area of the molten iron, the flow velocity of the molten iron, and the charging duration, the accurate calculation of the molten iron charged into the ladle is realized, and there is no need for a rail scale measurement. Then, according to the charged weight of the molten iron in the ladle, the flipping control of the molten iron launder is carried out, so that the molten iron stops being injected into the ladle, thereby improving the accuracy of controlling the charged amount of the molten iron.

[0114] After the calibration of the molten iron cross-sectional area measurement part and the molten iron flow rate measurement part is completed, the formula can be calibrated for k using the weighing data of the rail scale. When there are different process conditions, for example, S1 and V1 are obtained by calibration under the first process condition, and S2 and V2 are obtained by calibration under the second process condition, then the calibration coefficient k1 corresponding to the first process condition and the calibration coefficient k2 corresponding to the second process condition can be calibrated.

[0115] Figure 12 This is a schematic structural diagram of another molten iron charging amount control system provided by the embodiments of the present disclosure. As Figure 12 shown, the molten iron charging amount control system further includes a ladle number identification unit 550, a radar level gauge 560, and a rail scale 570.

[0116] Among them, the ladle number identification unit 550 is used to identify the ladle number information of the ladle, and the ladle number information may include, but is not limited to, information such as the ladle type and the charging amount control requirements of the ladle. The radar level gauge 560 is used to measure the height of the molten iron in the ladle. The rail scale 570 is used to weigh the ladle and the molten iron, and it can be a dynamic rail scale or a static rail scale, and no specific limitation is made here.

[0117] Specifically, the ladle number identification unit 550 can read the ladle number information of the molten iron ladle under the blast furnace. According to this ladle number information, the empty ladle weight W0 weighed by the rail scale for this molten iron ladle can be obtained. According to the control requirements such as the ladle type and filling amount of this molten iron ladle, the ladle filling amount control system gives the filling amount control parameter value (i.e., the preset weight threshold) and the liquid level upper limit control value. Further, the ladle filling amount control system issues the receivable molten iron information, and the blast furnace tapping system starts to release molten iron. The ladle filling amount control system measures data such as the cross-sectional area of the molten iron in the runner, the flow rate of the molten iron in the runner, the duration of filling the ladle with molten iron, and the liquid level, etc. Then, based on the cross-sectional area of the molten iron in the runner, the flow rate of the molten iron in the runner, and the duration of filling the ladle with molten iron, cumulative calculation is performed to obtain the filling weight of the molten iron in the ladle. When the filling weight of the molten iron in the ladle reaches the filling amount control parameter value, the ladle filling amount control system issues a runner chute flipping signal to flip the runner chute flap, and the molten iron stops flowing into the current molten iron ladle.

[0118] In some embodiments, if the filling weight of the molten iron in the ladle does not reach the filling amount control parameter value, but the liquid level of the radar level gauge has reached the liquid level upper limit control value, then the ladle filling amount control system also issues a runner chute flipping signal to stop filling the ladle with molten iron.

[0119] The technical solution of the embodiment of the present disclosure obtains the cross-sectional area of the molten iron in the runner, the flow rate of the molten iron in the runner, and the duration of filling the ladle with molten iron, and then determines the filling weight of the molten iron in the ladle based on the cross-sectional area of the molten iron in the runner, the flow rate of the molten iron in the runner, and the duration of filling the ladle with molten iron; when the filling weight of the molten iron in the ladle meets the condition for stopping filling the molten iron, a runner chute flipping signal is sent to flip the runner chute. In the above technical solution, through the cross-sectional area of the molten iron, the flow rate of the molten iron, and the filling duration, accurate calculation of the molten iron filled in the ladle is achieved without the need for rail scale measurement. Then, based on the filling weight of the molten iron in the ladle, the runner chute flipping control is performed to stop injecting the molten iron into the ladle, thereby improving the accuracy of the molten iron filling amount control.
