In order to better understand the technical scheme of the invention, the technical scheme of the invention is described in detail in the following with the accompanying drawings and specific embodiments.
First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
As shown in fig. 1, the method for optimizing a converter automatic tapping model curve according to the present embodiment includes:
step S1, acquiring the automatic converter posture adjustment amount and the manual converter posture adjustment amount when the converter tilts at each step in each automatic steel tapping process of the converter;
s2, after the converter finishes a plurality of automatic steel tapping processes, determining a converter attitude automatic adjustment target value corresponding to each step of tilting according to a plurality of converter attitude automatic adjustment quantities corresponding to each step of tilting of the converter, and determining a converter attitude manual adjustment target value corresponding to each step of tilting according to a plurality of converter attitude manual adjustment quantities corresponding to each step of tilting of the converter;
and S3, correcting the target angle of the converter automatic steel tapping model curve corresponding to each step of tilting according to the converter attitude automatic adjustment target value corresponding to each step of tilting and the converter attitude manual adjustment target value.
As shown in fig. 2 and 3, the converter tapping system comprises a converter, a ladle and an alloy chute, wherein the converter, the ladle and the alloy chute move in a chain manner according to a preset model. The converter is a molten steel smelting device, the converter is tilted after smelting is finished to enable molten steel to flow out of the steel outlet, and steel slag floats on the surface of the molten steel in the steel tapping process.
The steel 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 steel ladle, and when the molten steel flowing out of the converter exceeds 1/3 of the total weight, the alloy chute is aligned with the steel flow and adds the alloy to the steel ladle.
In the embodiment, in each automatic tapping process of the converter, when the converter tilts for each step, if the converter mouth overflows slag, the first-level control system L1 issues an instruction for gradually reducing the speed of the converter and stopping the converter, fine-tuning the converter without interrupting the automatic tapping, and controlling the converter to lift back, wherein the single adjustment amount is δ, as shown in fig. 2, after the fine-tuning is performed for one time, whether the converter mouth overflows slag is judged again, if yes, the fine-tuning of the converter is repeated, but the total adjustment amount does not exceed the set maximum value δ max; when the slag tapping detection system detects that molten steel slag entrapment occurs in the converter steel tapping hole under the condition that steel tapping is not finished, the converter is automatically pressed down under the condition that automatic steel tapping is not interrupted, the single adjustment amount is-delta, as shown in fig. 3, after the operation is executed, whether the molten steel slag entrapment phenomenon exists in the converter steel tapping hole under the condition that steel tapping is not finished is judged again, if yes, the instruction is executed repeatedly, and the total adjustment amount is not less than the set minimum value-delta max. The converter posture automatic adjustment amount in the step S1 is a total adjustment amount of the primary control system L1 for fine adjustment of the converter posture at each step of tilting of the converter.
In each automatic tapping process of the converter, when the converter tilts at each step, when a converter operator pre-judges that dross on the surface of molten steel in the converter is about to overflow a converter mouth of the converter, the angle of the converter is raised by pressing a 'slight lifting' button on an operation platform behind the converter, the single adjustment amount is xi, as shown in figure 2, the steel slag is prevented from dripping into a steel ladle or splashing onto a molten steel trolley track bearing the steel ladle, and the total adjustment amount does not exceed a set maximum upward-facing value xi max; when a converter rocking worker finds that converter scum is deeper away from the converter edge, the converter angle needs to be pressed down by pressing a 'micro-drop' button on a rear operation platform of the converter, and the single adjustment amount-xi is shown in figure 3, so that the tapping steel flow keeps higher ferrostatic pressure, the steel slag is prevented from being carried out by molten steel from a tapping hole, the tapping efficiency is improved, and the total adjustment amount does not exceed the set maximum pressing value-xi max. The manual converter posture adjustment amount in the step S1 is the total adjustment amount of the converter shaking worker for adjusting the converter posture when the converter tilts at each step.

Of course, after the maximum value and the minimum value of all the converter posture automatic adjustment quantities corresponding to each tilting are removed, the average value of the remaining converter posture automatic adjustment quantities can be obtained to obtain the converter posture automatic adjustment target value.
In step S2, determining a converter attitude manual adjustment target value corresponding to each step of tilting according to a plurality of converter attitude manual adjustment amounts corresponding to each step of tilting of the converter, including: calculating the average value of all converter attitude manual adjustment quantities corresponding to each step of tilting of the converter to obtain a converter attitude manual adjustment target value corresponding to the step of tilting, and expressing the manual adjustment target value as follows by using a formula: Δ M i ＝(ξ i1 +ξ i2 +…+ξ in )/n；ξ in Manually adjusting the converter posture corresponding to the ith tilting in the nth automatic steel tapping process by delta M i And manually adjusting the target value for the converter attitude corresponding to the ith tilting. Of course, after the maximum value and the minimum value of all converter posture manual adjustment amounts corresponding to each tilting step are removed, the average value of the remaining converter posture manual adjustment amounts can be obtained to obtain the converter posture manual adjustment target value.
