Abstract
Description
Background Art
[0002] Ladle Furnace (LF) furnace has become a rising star in the metallurgical industry due to its simple equipment, low investment cost, flexible operation and good refining effect. LF furnace refining mainly relies on the white slag in the ladle. In a low-oxygen atmosphere (oxygen content is 5%), argon is blown into the ladle for stirring and the molten steel passing through the primary refining furnace is heated by graphite electrodes for refining. Since argon stirring accelerates the chemical reaction between slag and steel, arc heating is used for temperature compensation, which can ensure a longer refining time, thereby reducing the oxygen and sulfur content in the steel.
[0003] However, in the existing refining soft blowing process, it is usually the operator who observes the bottom blowing port flow in the refining furnace in real time and controls the bottom blowing port flow in real time. The problem is that the operator's observation accuracy through the naked eye is low and errors are prone to occur, resulting in poor soft blowing effects and more inclusions in the molten steel.

[0045] The implementation details of the technical solution of the embodiment of the present application are described in detail below:
[0046] According to one aspect of the present application, a method for controlling argon gas flow is provided. Figure 1 FIG. 1 is a flow chart of an argon gas flow control method according to an embodiment of the present application. Figure 2 As shown, Figure 2 This is an example diagram of image data obtained when the target refining furnace performs soft blowing on molten steel. The argon gas flow control method includes at least steps 110 to 130, which are described in detail as follows:
[0047] In step 110, when the target refining furnace is operated at a preset initial bottom blowing flow rate value, image data inside the target refining furnace is acquired.
[0048] Specifically, Figure 2 As shown, Figure 2This is an example diagram of image data obtained when the target refining furnace performs soft blowing on molten steel, which includes two bottom blowing ports. The parameters of the two bottom blowing ports can be compared with the parameters of the reference bottom blowing port to determine whether the two bottom blowing ports have achieved the desired soft blowing effect.
[0049] Furthermore, in the embodiment of the present application, image data in a target refining furnace is collected by a camera, and then bottom blowing port parameters of the target refining furnace in the image data are obtained by a calculation model.
[0050] In one embodiment of the present application, before the target refining furnace is operated at a preset initial bottom blowing flow rate value, the method further includes:
[0051] Acquire the type of steel in the target refining furnace and the pipeline pressure in the target refining furnace;
[0052] The initial bottom blowing flow rate value is determined according to the steel type and the pipeline pressure.
[0053] By obtaining the steel type and pipeline pressure in the target refining furnace and the empirical value obtained through historical statistics, a preset initial bottom blowing flow value is input into the target refining furnace through the controller. However, the target refining furnace does not always operate according to the initial bottom blowing flow value. If the bottom blowing port parameters obtained by image data analysis are inconsistent with the benchmark bottom blowing port parameters, the initial bottom blowing flow value needs to be adjusted to achieve the best soft blowing effect.
[0054] Furthermore, for each different type of steel and the pipeline pressure of the current target refining furnace, after the bottom blowing flow rate of the target refining furnace is adjusted and the final bottom blowing flow rate is confirmed, the final bottom blowing flow rate is used as the latest empirical value. The next time the target refining furnace needs to soft-blow the steel type under the corresponding pipeline pressure, the latest empirical value is input, that is, the final bottom blowing flow rate value mentioned above is input. The bottom blowing flow rate value can be self-learned through a preset model to obtain the optimal soft blowing flow values of different steel grades under different pipeline pressures, so as to quickly achieve the best soft blowing effect.
[0055] In step 120, bottom blowing port parameters are determined according to the image data, and the bottom blowing port parameters are compared with reference bottom blowing port parameters.
[0056] In one embodiment of the present application, determining the bottom blowing port parameters according to the image data includes:
[0057] Acquire the area of slag floating on the surface of molten steel in the target refining furnace and the surface area of molten steel in the target refining furnace according to the image data;
[0058] The bottom blowing port area of the target refining furnace is determined according to the slag area and the surface area of the molten steel.
[0059] Specifically, the preset calculation model can be used to analyze the area of slag floating on the surface of molten steel in the target refining furnace and the surface area of molten steel in the target refining furnace. Then, the corresponding bottom blowing mouth area can be obtained by subtracting the slag area from the surface area of molten steel. In other words, the size of the bottom blowing mouth area can be used to judge whether the current soft blowing effect reaches the preset optimal soft blowing effect. The optimal soft blowing effect can be judged by the preset benchmark bottom blowing mouth area.
[0060] In one embodiment of the present application, the reference bottom blowing port parameter is a reference bottom blowing port area, and comparing the bottom blowing port parameter with the reference bottom blowing port parameter comprises:
[0061] The size relationship between the bottom blowing port area and the reference bottom blowing port area is compared.
[0062] Specifically, the size of the bottom blowing port area is used to judge whether the current soft blowing effect reaches the preset optimal soft blowing effect. The optimal soft blowing effect can be judged by the preset reference bottom blowing port area. That is to say, if the bottom blowing port area in the current target refining furnace is consistent with the preset reference bottom blowing port area, it means that the optimal soft blowing effect has been achieved in the refining furnace.
[0063] In step 130, if the bottom blowing port parameters are inconsistent with the reference bottom blowing port parameters, the bottom blowing flow rate of the target refining furnace is adjusted at least once until the bottom blowing port parameters are consistent with the reference bottom blowing port parameters after adjustment.
[0064] Specifically, if the bottom blowing mouth parameters are inconsistent with the reference bottom blowing mouth parameters, it means that the soft blowing effect in the target refining furnace has not reached the preset optimal soft blowing effect. Then, what affects the soft blowing effect is the bottom blowing flow rate of the target refining furnace. At this time, the bottom blowing flow rate of the target refining furnace is adjusted at least once until the bottom blowing mouth parameters are consistent with the reference bottom blowing mouth parameters after the adjustment, which means that the soft blowing effect reaches the preset optimal soft blowing effect.
[0065] In one embodiment of the present application, if the bottom blowing port parameter is inconsistent with the reference bottom blowing port parameter, adjusting the bottom blowing flow rate of the target refining furnace at least once includes:
[0066] If the bottom blowing port area is smaller than the reference bottom blowing port area, a first bottom blowing flow value after the current adjustment is determined according to the difference between the bottom blowing port area and the reference bottom blowing port area, and the first bottom blowing flow value is greater than the bottom blowing flow value at the last adjustment;
[0067] Input the first bottom blowing flow value after adjustment, and obtain the adjusted first bottom blowing port adjustment area after adjustment after a first preset time;
[0068] If the first bottom blowing port adjustment area is not consistent with the reference bottom blowing port area, the next adjustment is performed according to the difference between the first bottom blowing port adjustment area and the reference bottom blowing port area until the first bottom blowing port adjustment area is consistent with the reference bottom blowing port area.
[0069] Specifically, if the bottom blowing port area is smaller than the reference bottom blowing port area, it means that the bottom blowing flow rate of the target refining furnace needs to be increased to increase the bottom blowing port area to approach the reference bottom blowing port area. By the difference between the bottom blowing port area and the reference bottom blowing port area, if the difference is too large, the bottom blowing flow rate of the target refining furnace is greatly increased. If the difference is small, the bottom blowing flow rate of the target refining furnace can be slightly increased. The specific difference corresponding to the bottom blowing port flow rate to be adjusted can be shown in Table 1. It should be noted that Table 1 is only an exemplary description, and the numerical value is not limited here. The above difference is used to make the adjusted first bottom blowing port adjustment area quickly approach the reference bottom blowing port area.
[0070] Furthermore, the first preset time can be set according to actual needs. In the present application, the first preset time can be specifically 30-45 seconds, because after increasing the bottom blowing flow rate of the target refining furnace, it is necessary to wait for the reaction time of the argon blowing gas to change. After the first preset time, the adjusted first bottom blowing port adjustment area is obtained. If the first bottom blowing port adjustment area is not consistent with the reference bottom blowing port area, the next adjustment is performed according to the difference between the first bottom blowing port adjustment area and the reference bottom blowing port area until the first bottom blowing port adjustment area is consistent with the reference bottom blowing port area.
[0071] In one embodiment of the present application, if the bottom blowing port parameter is inconsistent with the reference bottom blowing port parameter, adjusting the bottom blowing flow rate of the target refining furnace at least once includes:
[0072] If the bottom blowing port area is larger than the reference bottom blowing port area, a second bottom blowing flow value after the current adjustment is determined according to the difference between the bottom blowing port area and the reference bottom blowing port area, and the second bottom blowing flow value is smaller than the bottom blowing flow value at the last adjustment;
[0073] Input the second bottom blowing flow value after adjustment, and obtain the adjusted second bottom blowing port adjustment area after the second preset time;
[0074] If the second bottom blowing port adjustment area is not consistent with the reference bottom blowing port area, the next adjustment is performed according to the difference between the second bottom blowing port adjustment area and the reference bottom blowing port area until the second bottom blowing port adjustment area is consistent with the reference bottom blowing port area.
[0075] Specifically, if the bottom blowing port area is larger than the reference bottom blowing port area, it means that the bottom blowing flow rate of the target refining furnace needs to be reduced so that the bottom blowing port area is reduced to approach the reference bottom blowing port area. By the difference between the bottom blowing port area and the reference bottom blowing port area, if the difference is too large, the bottom blowing flow rate of the target refining furnace is greatly increased, and if the difference is small, the bottom blowing flow rate of the target refining furnace can be slightly increased. The specific difference corresponding to the bottom blowing port flow rate to be adjusted can also be shown in Table 1. It should be noted that Table 1 is only an exemplary description, and the numerical value is not limited here. The above difference is used to make the adjusted second bottom blowing port adjustment area quickly approach the reference bottom blowing port area.
[0076]
[0077] In one embodiment of the present application, after the bottom blowing port parameters are consistent with the reference bottom blowing port parameters, the method further includes:
[0078] Acquire target bottom blowing mouth parameters that are consistent with the reference bottom blowing mouth parameters;
[0079] The target bottom blowing port parameter is used as the target initial bottom blowing flow rate value required for the next soft blowing of the target refining furnace on the type of steel under the pipeline pressure.
[0080] Specifically, after the bottom blowing mouth parameters are consistent with the reference bottom blowing mouth parameters, the target bottom blowing mouth parameters that are consistent with the reference bottom blowing mouth parameters are obtained, that is, the bottom blowing flow rate value in the target refining furnace is obtained at this time, and the current bottom blowing flow rate value is used as the target initial bottom blowing flow rate value required for the target refining furnace to soft blow the steel type under the pipeline pressure next time. As shown in Table 2, through continuous adjustment and refining furnace tests, the optimal initial bottom blowing flow rate values for different steel grades under different pipeline pressures can be obtained. For example, the current steel type is AA302023 at a pipeline pressure of 0.6-0.5MPa, and the system prompts the optimal initial bottom blowing flow rate value of 50NL / min (standard liters / minute), while in the actual refining furnace soft blowing, the bottom blowing flow rate value when the best soft blowing effect is achieved is 53NL / min. At this time, the corresponding content in Table 1 can be updated, and the optimal initial bottom blowing flow rate corresponding to the steel type AA302023 at a pipeline pressure of 0.6-0.5MPa is updated from 50NL / min to 53NL / min.
[0081]
[0082] Table 2
[0083] The beneficial effects that can be achieved by the embodiments of the present application are: transforming manual naked eye observation into a visualized soft blowing effect and achieving standardization of the argon blowing flow rate in the soft blowing stage; eliminating the poor soft blowing effect caused by factors such as equipment, which causes unqualified inclusion detection in finished products; and effectively reducing the workload of operators, significantly improving the level of automation, and improving the safety of workers and equipment.
[0084] To summarize, in the technical solution of the embodiment of the present application, when the target refining furnace is operating at a preset initial bottom blowing flow rate value, the bottom blowing mouth parameters can be determined by acquiring image data within the target refining furnace, and by comparing the bottom blowing mouth parameters with the benchmark bottom blowing mouth parameters, it can be determined whether the soft blowing effect achieved by the current initial bottom blowing flow rate value is consistent with the soft blowing effect corresponding to the benchmark bottom blowing mouth parameters.
[0085] If the bottom blowing mouth parameters are inconsistent with the reference bottom blowing mouth parameters, it means that the current soft blowing effect has not achieved the required soft blowing effect, and the bottom blowing flow rate of the target refining furnace is adjusted at least once until the bottom blowing mouth parameters are consistent with the reference bottom blowing mouth parameters after adjustment. That is, the present application can automatically adjust the bottom blowing flow rate of the target refining furnace so that the bottom blowing mouth parameters are consistent with the reference bottom blowing mouth parameters, thereby improving the soft blowing effect on molten steel in the refining furnace, and improving the efficiency of automatic adjustment of soft blowing, thereby reducing labor costs.
