Description

Background Art

[0002] Converter steelmaking uses hot metal and scrap steel as the main raw materials, and uses slag-making materials such as lime, lightly burned dolomite, and ore as auxiliary materials. A high-speed oxygen jet is blown into the furnace through an oxygen lance, so that oxygen, slag-making materials, and coolant react with hot metal in the furnace to undergo complex physical and chemical reactions, achieving the purpose of removing impurities in the molten steel and increasing the temperature of the molten steel. Due to the numerous influencing factors of materials, operations, and equipment in converter steelmaking, production is prone to fluctuations, production still relies on experience, and the degree of unmanned operation is low.

[0003] However, the reaction speed of converter steelmaking is fast and the smelting cycle is short. The slag melting effect during the smelting process directly affects the quality of molten steel and the steelmaking efficiency. The slag melting effect during the smelting process is closely related to the flame effect in the converter. In existing methods, the flame effect is usually adjusted through manual intervention, and this method has the problem of inaccurate adjustment, which in turn leads to the inability to effectively achieve the purpose of converter steelmaking.

[0046] The implementation details of the technical solutions of the embodiments of the present application are elaborated in detail as follows:

[0047] First of all, it should be noted that the control scheme of the converter oxygen lance proposed in the present application can be applied to the related technical fields of converter steelmaking. By obtaining various different control modes of the converter oxygen lance, different feeding operations can be carried out according to different control modes, and thus the diversity of converter steelmaking in different modes can be adapted. At the same time, the flame index of the converter under different control modes can be obtained, and then the position of the converter oxygen lance can be adjusted according to the obtained flame index so that the flame index can be adjusted to the preset range, thereby improving the quality and efficiency of converter steelmaking.

[0048] According to one aspect of the present application, a control method for a converter oxygen lance is provided. Figure 1 FIG. is a flowchart of the control method for the converter oxygen lance shown according to the embodiments of the present application. The control method for the converter oxygen lance at least includes steps 110 to 140, which are introduced in detail as follows:

[0049] In step 110, obtain the control mode of the converter oxygen lance.

[0050] Specifically, there can be various control modes for the converter oxygen lance. For example, the converter oxygen lance can be controlled solely based on the flame index, or controlled based on both the flame index and the audio index, etc., which can adapt to a variety of different control modes. Under different control modes, the adjustment methods for the converter oxygen lance will be different. Therefore, the control method for the converter oxygen lance provided in this application can adapt to a variety of different control modes, thereby improving the diversity of converter steelmaking.

[0051] In step 120, perform a preset feeding operation in the converter based on the control mode.

[0052] In an embodiment of this application, the control mode includes a preset first control mode and a preset second control mode, and the feeding operation includes a first feeding operation and a second feeding operation. Refer to Figure 2 , step 120 can be carried out according to steps S1 - S2:

[0053] Step S1: If the control mode is the first control mode, perform the first feeding operation in the converter.

[0054] Step S2: If the control mode is the second control mode, perform the second feeding operation in the converter.

[0055] Specifically, the preset first control mode can be set according to actual needs. In the embodiment of this application, the first control mode is specifically a mode in which the position of the converter oxygen lance is adjusted according to the flame index in the converter, that is, the influencing factor for adjusting the position of the converter oxygen lance is the flame index in the converter.

[0056] Furthermore, the preset second control mode can also be set according to actual needs. In the embodiment of this application, the second control mode is specifically a mode in which the position of the converter oxygen lance is adjusted according to the flame index in the converter and the audio index of the sonar device in the converter, that is, the influencing factors for adjusting the position of the converter oxygen lance are the flame index in the converter and the audio index of the sonar device.

[0057] Furthermore, the preset first feeding operation can be set according to actual needs. In the embodiment of this application, the first feeding operation can specifically be adding 500 kg of materials into the converter. The preset second feeding operation can also be set according to actual needs. In the embodiment of this application, the second feeding operation can specifically be carried out in two batches. The first batch of feeding is adding 500 kg of materials into the converter, and the second batch is adding another 250 kg of materials into the converter.

[0058] In an embodiment of the present application, different feeding operations are performed under different control modes to obtain corresponding flame indices, and then different operations are performed on the obtained different flame indices, so that the oxygen lance can continuously adjust its position to control the flame index in the converter and ensure that the foaming degree of the converter is within an appropriate range.

[0059] In step 130, the flame index of the converter is obtained based on the feeding operation after a preset time.

[0060] In an embodiment of the present application, the preset time includes a first preset time and a second preset time. The obtaining of the flame index of the converter based on the feeding operation after a preset time includes:

[0061] If the feeding operation is the first feeding operation, the flame index of the converter is obtained after the first preset time;

[0062] If the feeding operation is the second feeding operation, the flame index of the converter is obtained after the second preset time.

[0063] Specifically, the first preset time and the second preset time can be set according to actual needs. In the embodiment of the present application, the first preset time can be specifically 2 minutes, and the second preset time can be specifically 4 minutes and 40 seconds. As mentioned above, the first feeding operation only requires one batch of feeding, while the second feeding operation requires two batches of feeding. Therefore, the first preset time is significantly less than the second preset time.

[0064] By performing different feeding operations to obtain the corresponding flame index of the converter after different times, the flame index of the converter can be obtained more accurately, improving the accuracy of obtaining the flame index.

[0065] In step 140, the position of the converter oxygen lance is adjusted based on the flame index and the control mode.

[0066] In an embodiment of the present application, step 140 can be carried out according to steps S3 - S4:

[0067] Step S3: If the control mode is the first control mode and the flame index is lower than a preset first threshold, lower the oxygen lance of the converter so that the flame index is within the preset flame index range.

[0068] Step S4: If the control mode is the first control mode and the flame index is higher than a preset second threshold, raise the oxygen lance of the converter so that the flame index is within the preset flame index range.

[0069] Specifically, the preset first threshold, the preset second threshold, and the preset flame index range can all be set according to actual needs. In the embodiments of the present application, the preset first threshold can specifically be 10%, the preset second threshold can specifically be 20%, and the preset flame index range can specifically be between 10% and 20%.

[0070] Further, if the current control mode is the first control mode, the control method at this time is as follows: When the flame index is less than 10%, the oxygen lance descends at a speed of 50 mm each time. Each time the oxygen lance descends, the flame index of the converter will be judged again until the flame index is 10% - 20%, and then the lance lowering operation will no longer be performed; when the flame index is greater than 20%, the oxygen lance rises at a speed of 100 mm each time. Each time the oxygen lance rises, the flame index of the converter will be judged again until the flame index is 10 - 20%, and then the lance raising operation will no longer be performed.

[0071] Further, if the current control mode is the second control mode, the sonar device's audio index in the converter will be combined for adjustment at this time. The control method at this time is as follows:

[0072] When the flame index is less than 10%, the audio index at this time is generally lower than 10%. The oxygen lance descends at a speed of 50 mm each time. At this time, the audio index is increased to the range of 10% - 20% through the sonar device. Each time the oxygen lance descends, the flame index of the converter will be judged again until both the flame index and the audio index are within 10% - 20%, and then the lance stopping operation is performed.

[0073] When the flame index is greater than 20%, the audio index at this time is generally higher than 20%. The oxygen lance rises at a speed of 100 mm each time. At this time, the audio index is decreased to the range of 10% - 20% through the sonar device. Each time the oxygen lance rises, the flame index of the converter will be judged again until both the flame index and the audio index are within 10% - 20%, and then the lance stopping operation is performed.

[0074] In an embodiment of the present application, the method provided by the present application further includes:

[0075] If the flame index is higher than the preset third threshold, a preset dose of slag-making agent is added to the converter to make the flame index within the preset flame index range, where the third threshold is higher than the second threshold.

[0076] Specifically, the preset third threshold and the preset dosage of the slag-making agent can both be set according to actual needs. In the embodiments of the present application, the preset third threshold can specifically be 40%. That is, when the flame index of the converter is higher than 40%, at this time, simply adjusting the position of the converter oxygen lance can no longer effectively adjust the flame index of the converter, and an appropriate amount of slag-making agent needs to be added to reduce the flame index to between 10% and 20%.

[0077] In an embodiment of the present application, the method provided by the present application can also be carried out according to steps 150-170:

[0078] Step 150: If the flame index is within the preset flame index range, determine whether the converter oxygen lance reaches the preset end-stop position.

[0079] Step 160: If the converter oxygen lance does not reach the preset end-stop position, lower the converter oxygen lance to make the converter oxygen lance reach the end-stop position.

[0080] Step 170: If the converter oxygen lance reaches the preset end-stop position, stop the converter oxygen lance and calculate the dynamic blowing oxygen consumption of the converter.

[0081] In the embodiments of the present application, the preset end-stop position can be set according to actual needs, and the preset end-stop position can specifically be the lowest position in the converter. If the converter oxygen lance does not reach the preset end-stop position, then the converter oxygen lance needs to be further lowered until the oxygen lance reaches the end-stop position. If the converter oxygen lance reaches the end-stop position, then at this time, the dynamic blowing oxygen consumption can be determined by measuring the sublance or the bomb measurement point.

[0082] Furthermore, the control method of the converter oxygen lance provided by the embodiments of the present application can also be used for converters without intermediate measuring devices such as sublances or bombs: after adding a batch of materials to the converter, determine the flame index at this time; when the flame index is 10% - 20%, if the lance position has not been dynamically adjusted, the lance position is controlled to the next step according to the normal oxygen step; when the flame index is less than 10%, the oxygen lance is lowered at a speed of 50 mm each time. Each time the oxygen lance is lowered, the flame index of the converter is judged again. The lowest lance position drops to the end blowing position until the flame index is 10 - 20%, and then the adjusted lance position is maintained and the next step is entered; when the flame index is greater than 20%, the oxygen lance is lifted at a speed of 100 mm each time. Each time the oxygen lance is lifted, the flame index of the converter is judged again. The highest lance position is lifted to the highest blowing point position. If the oxygen lance is already at the high position and the flame index is greater than 40% at this time, then a slag-making agent can be added for adjustment until the flame index is 10 - 20%, and then the adjusted lance position is maintained.

[0083] When the converter smelting reaches the end-point gun lowering point, the lance position of the oxygen lance gets out of the control of the flame index. If the oxygen lance is not at the blowing end-point position, the oxygen lance automatically descends to the end-point lance position at a speed of 50 mm per step every 2 seconds; if the converter smelting does not reach the end-point gun lowering point, continue to lower the lance to make the oxygen lance reach the end-point position; at this time, continue blowing, and the end point can be judged according to the furnace mouth flame or flue gas analysis. When reaching the end point, raise the lance. The oxygen lance is raised to the oxygen cut-off point to cut off oxygen, and is raised to the waiting position to stop the lance.

[0084] For a better explanation of the above embodiments, the following examples can be used for understanding:

[0085] Example 1: In the first control mode, that is, only using the flame index control, the material parameters at this time are: 33 t of scrap steel charged into the furnace, 204 t of hot metal charged into the furnace, and the silicon content in the hot metal is 0.17%. The lance position at the start of blowing is 2.5 m. After 2 minutes of blowing, a batch of materials is added. At this time, the detected flame index is 16%, and the lance position remains at 2.5 m. When blowing to 3'40", the flame index is detected. At this time, the flame index is 12%. After 25", the flame index becomes 8%, and the oxygen lance descends 100 mm. The lance position remains at the lowered lance position; after 10", the flame index is still 8%, and the oxygen lance continues to descend 100 mm. At this time, the flame index is 12%, and the lance position remains at the lowered lance position; when blowing to 6'12", the flame index is 9%, and the oxygen lance descends 100 mm. The flame index becomes 13%, and the lance position remains at the lowered lance position; when blowing to 7'40", the flame index is 22%, and at this time, the lance is raised 100 mm. The flame index becomes 15%, and the lance position remains at the raised lance position. When blowing to 10'09", it reaches the sublance measurement point, gets out of the control of the flame index, and the oxygen lance automatically descends to the end-point lance position of 1.7 m at a speed of 50 mm per step every 2 seconds; measure the sublance, the oxygen lance maintains the end-point lance position, continues blowing to the end point, and automatically raises the lance.

[0086] Example 2: In the second control mode, that is, combined control of the flame index and the audio index, the material parameters at this time are as follows: 33 t of scrap steel charged into the furnace, 204 t of hot metal charged into the furnace, and the silicon content in the hot metal is 0.38%. The lance position at the start of blowing is 2.2 m. After 3 minutes and 37 seconds of blowing, a batch of materials is added, and then the addition of the second batch of materials continues. At this time, the flame index is 19%, and the lance position is maintained at 2.2 m. At this time, the audio index is input, and the audio index is 17%; when blowing reaches 6 minutes and 11 seconds, the audio index is 8%, the flame index is 9%, the lance position drops by 100 mm, the audio index becomes 13%, the flame index is 12%, and the lance position is maintained at the lowered lance position; at 6 minutes and 54 seconds, the audio index is 24%, the flame index is 21%, the oxygen lance is raised by 100 mm. At this time, the audio index is 18%, the flame index is 17%, and the lance position is maintained at the raised lance position; when blowing reaches 10 minutes and 18 seconds, the audio index is 23%, the flame index is 22%, the oxygen lance is raised by 100 mm, the audio index is 17%, the flame index becomes 15%, and the lance position is maintained at the raised lance position; when blowing reaches 11 minutes and 57 seconds, the sublance measurement point is reached, and the control by the audio index and the flame index is released. The oxygen lance automatically drops to the end lance position of 1.7 m at a speed of 50 mm per step every two seconds; the sublance is measured, the oxygen lance maintains the end lance position, and blowing continues to the end point, and the lance is automatically raised.

[0087] Example 3: The first control mode is adopted, that is, separate control of the flame index, without a sublance and without sonar slag melting. The material parameters at this time are as follows: 33 t of scrap steel charged into the furnace, 204 t of hot metal charged into the furnace, and the silicon content in the hot metal is 0.29%. The lance position at the start of blowing is 2.4 m. After 1 minute and 48 seconds of blowing, a batch of materials is added. At this time, the flame index is 15%, and the lance position is maintained at 2.4 m. When blowing reaches 2 minutes and 53 seconds, the second batch of materials starts to be added, and when the second batch of materials is added at 3 minutes and 58 seconds, the flame index is 17%, and the lance position is maintained at 2.4 m; when blowing reaches 4 minutes and 23 seconds, the flame index is still 8%, the oxygen lance drops by 100 mm. At this time, the flame index is 14%, and the lance position is maintained at the lowered lance position; when blowing reaches 5 minutes and 53 seconds, the flame index is 23%, the oxygen lance is raised by 100 mm, the flame index becomes 24%, and the lance position is maintained at the lowered lance position; 20 seconds later, the flame index is 25%, and the lance is continued to be raised by 100 mm, the flame index becomes 18%, and the lance position is maintained at the raised lance position; when blowing reaches 11 minutes and 09 seconds, the lance lowering point is reached, and the control by the flame index is released. The oxygen lance automatically drops to the end lance position of 1.7 m at a speed of 50 mm per step every two seconds; blowing continues, and the end point is judged by the flue gas composition. When the end point is reached, the lance is automatically raised.
