Therefore, the temperatures of the upper area and the lower area in the ladle can be obtained and determined in time, and accurate basis is provided for controlling the wire feeding speed of the guiding device.

Optionally, S02, controlling the wire feeding speed of the guiding device according to the temperature, comprises:

the wire feeding speed of the guide means is controlled according to the temperature of the upper region and the temperature of the lower region in the ladle.

Therefore, the wire feeding speed of the guide device can be matched with the temperature of molten steel in the ladle, and the cored wire is favorably conveyed into the ladle and melted by the molten steel better, so that a nodulizer can be diffused into the molten steel more uniformly, and the uniformity of spheroidizing treatment is improved.

Optionally, controlling the wire feed speed of the guiding means according to the temperature of the upper zone and the temperature of the lower zone in the ladle comprises:

determining a difference between a temperature of a lower region within the ladle and a temperature of an upper region thereof;

and controlling the wire feeding speed of the guide device according to the difference value.

Therefore, the melting speed of the core-spun yarn in the molten steel is different due to the different temperatures of the upper part and the lower part of the molten steel in the ladle, so that the yarn feeding speed of the guide device is controlled according to the difference between the temperature of the lower part area and the temperature of the upper part area in the ladle, the conveying speed of the core-spun yarn can be matched with the temperature of the molten steel, the core-spun yarn is favorably in better contact with the molten steel, the core-spun yarn can be more uniformly diffused into the molten steel after being melted by the molten steel, and the spheroidizing effect is improved.

Optionally, controlling the wire feeding speed of the guiding device according to the difference comprises:

when the difference value is larger than the set value, the wire feeding speed of the guide device is increased;

and when the difference value is smaller than the set value, reducing the wire feeding speed of the guide device.

Therefore, the wire feeding speed of the guide device can be accurately controlled, the conveying speed of the core-spun wire is matched with the temperature of the molten steel, the core-spun wire can be uniformly diffused into the molten steel after entering the molten steel and being melted by the molten steel, and the spheroidizing effect is favorably improved.

It is understood that increasing or decreasing the feed speed of the guide means increasing or decreasing the rotational speed of the guide means.

For example, the set value is 100 ℃, when the temperature of the lower region in the ladle is 1200 ℃ and the temperature of the lower region is 1260 ℃, the difference is determined to be 60 ℃, and the difference 60 ℃ is smaller than the set value of 100 ℃, so that the wire feeding speed of the guiding device can be controlled to be reduced; when the temperature of the lower area in the ladle is 1300 ℃ and the temperature of the lower area is 1180 ℃, the difference is determined to be 120 ℃, and at the moment, the difference of 120 ℃ is greater than the set value of 100 ℃, so that the wire feeding speed of the guide device can be controlled to be increased.

Optionally, increasing or decreasing the feed rate of the guide comprises:

and controlling the rotating speed of the guiding device according to the corresponding relation between the difference value and the wire feeding speed.

Therefore, the rotation of the guide device can be accurately controlled according to the temperature difference between the upper area and the lower area of the molten steel in the ladle, the cored wire can be straightened and conveyed into the ladle better, and the cored wire can be uniformly diffused into the molten steel after being melted by the molten steel, so that the spheroidizing effect can be improved.

For example, when the difference is 20 ℃, the corresponding wire feeding speed is 10cm/s, and the rotating speed of the control guide device is 200r/s; when the difference is 30 ℃, the corresponding wire feeding speed is 20cm/s, and the rotating speed of the guide device is controlled to be 400r/s; when the difference is 40 ℃, the corresponding wire feeding speed is 30cm/s, and the rotating speed of the control guide device is 600r/s.

As shown in fig. 9, optionally, after controlling the wire feeding speed of the guiding device according to the temperature, the method further includes:

s03, acquiring image information of the surface of molten steel in a steel ladle;

and S04, controlling the opening and closing state of the shearing assembly according to the image information of the surface of the molten steel.

Therefore, the core-spun yarn can form residues to float on the surface of the molten steel after entering the molten steel to be melted, and the core-spun yarn can enter the molten steel to be melted and diffused better by acquiring the image information of the surface of the molten steel and controlling the on-off state of the shearing assembly according to the image information of the surface of the molten steel, so that the length of the core-spun yarn entering the molten steel is controlled accurately.

Referring to fig. 10, optionally, S04, controlling the opening and closing state of the shearing module according to the image information of the molten steel surface includes:

s41, determining the coverage area of the point distribution on the image information;

s42, calculating the number of the point objects in a unit area according to the coverage area of the distribution of the point objects;

s43, when the number of the dots in the unit area exceeds the set number, the cutting assembly is controlled to be opened.

Therefore, the length of the cored wire entering the molten steel can be accurately controlled, the phenomenon that the length of the cored wire entering the molten steel is too large to influence the spheroidization effect of the molten steel is avoided, and the spheroidization quality is improved.

For example, when the coverage area of the point objects on the acquired image information is 10cm < 2 >, the unit area is 3 cm < 2 >, and the set number is 10, the number of the point objects in the unit area of 3 cm < 2 > is calculated to be 12 at the moment, and the number exceeds the set number of 10, the cutting assembly is controlled to be started, and the cored wire is cut; when the coverage area of the point objects on the acquired image information is 10cm < 2 >, the unit area is 3 cm < 2 >, and the set number is 10, the number of the point objects in the unit area of 3 cm < 2 > is calculated to be 6 and less than the set number of 10, and the cutting assembly does not need to be controlled to be started.
