In order to better understand the technical scheme of the present invention, the following detailed description will refer to the accompanying drawings and specific embodiments.
First, the term "and/or" appearing herein is merely an association relationship describing associated objects, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
As shown in fig. 1, the method for optimizing the automatic tapping model curve of the converter according to the embodiment includes:
step S1, acquiring automatic regulating quantity of the converter posture and manual regulating quantity of the converter posture when the converter tilts each step in each automatic tapping process of the converter;
step S2, after the converter finishes the process of multiple times of automatic tapping, determining a converter posture automatic adjustment target value corresponding to each step of tilting according to a plurality of converter posture automatic adjustment amounts corresponding to each step of tilting of the converter, and determining a converter posture manual adjustment target value corresponding to each step of tilting of the converter according to a plurality of converter posture manual adjustment amounts corresponding to each step of tilting of the converter;
and step S3, correcting the target angle of the automatic converter tapping model curve corresponding to each step of tilting according to the automatic converter posture adjustment target value and the manual converter posture adjustment target value corresponding to each step of tilting.
As shown in fig. 2 and 3, the converter tapping system includes a converter, a ladle, and an alloy chute, which are interlocked according to a predetermined model. The converter is molten steel smelting equipment, after smelting, the converter is tilted to enable molten steel to flow out of the steel outlet, steel slag floats on the surface of the molten steel in the steel tapping process, and in order to improve the steel tapping efficiency, the converter is tilted to enable the steel outlet to maintain the maximum static pressure under the condition that the steel slag does not overflow from the converter outlet.
The ladle is a container for receiving molten steel flowing out of the converter, the alloy chute is a conveying device for adding alloy, aluminum slag balls and other materials to the ladle, and when the molten steel flowing out of the converter exceeds 1/3 of the total weight, the alloy chute aligns with the steel flow and adds the alloy to the ladle.
In this embodiment, when the converter tilts each step in each automatic tapping process, if the converter mouth has slag overflow, the primary control system L1 will issue an instruction to gradually slow down and stop the converter, fine-tune the converter without interrupting automatic tapping, control the converter to lift back, and make the single adjustment amount be δ, as shown in fig. 2, after the fine-tuning is performed once, it will be determined again whether the slag overflow exists at the converter mouth, if so, fine-tune the converter is repeated, but the total adjustment amount does not exceed the set maximum δmax; when the slag-down detection system detects that molten steel slag is rolled up at the tapping hole of the converter under the condition that tapping is not finished, the automatic tapping is not interrupted, the automatic pressing gesture is carried out on the converter, the single adjustment quantity is-delta, as shown in fig. 3, after the operation is carried out, whether the slag-up phenomenon is carried out at the tapping hole of the converter under the condition that tapping is not finished is judged again, if so, the instruction is repeatedly carried out, and the total adjustment quantity is not smaller than the set minimum value-delta max.

Of course, after the maximum value and the minimum value of all the automatic converter posture adjustment amounts corresponding to each step of tilting are removed, the average value of the remaining automatic converter posture adjustment amounts may be obtained to obtain the automatic converter posture adjustment target value.
In step S2, determining a manual adjustment target value of the converter posture corresponding to each step of tilting according to the manual adjustment amounts of the plurality of converter postures corresponding to the step of tilting, including: solving each tilting of the converterThe average value of all corresponding manual adjustment amounts of the converter gesture is used for obtaining a manual adjustment target value of the converter gesture corresponding to the tilting, and the manual adjustment target value is expressed as follows by a formula: ΔM i ＝(ξ i1 +ξ i2 +…+ξ in )/n；ξ in For the manual adjustment quantity of the converter gesture corresponding to the ith tilting in the nth automatic tapping process, delta M i And (5) manually adjusting a target value for the converter posture corresponding to the ith tilting. Of course, after the maximum value and the minimum value in all the manual adjustment amounts of the converter posture corresponding to each step of tilting are removed, the average value of the remaining manual adjustment amounts of the converter posture may be obtained to obtain the manual adjustment target value of the converter posture. The automatic converter attitude adjustment target value and the manual converter attitude adjustment target value for each step tilting shown in table 1 can be obtained by step S2.
