Description

Technical Field

[0001] The present invention belongs to the technical field of metallurgy, and particularly relates to a method, system, medium and electronic device for calculating the length of a continuous casting billet during continuous casting. Background Art

[0002] Continuous casting is a process in which liquid steel is cooled into a billet of a certain shape when passing through guiding devices such as a mold and segment, and is continuously pulled out of the segment at a certain speed by driving rolls, as Figure 1 shown. Among them, the tracking of the billet length is related to the control accuracy of the process control model, such as the liquid core tracking of the billet, the control of spray cooling water, the control of dynamic soft reduction, etc., which directly affects the quality of the continuous casting billet product.

The encoder rotates synchronously with the driving motor of the corresponding segment and generates counting pulses respectively, which are converted into the length of the billet for casting stream tracking. This scheme has poor accuracy and large cumulative errors due to over-reliance on a single motor device and encoder. Summary of the Invention

[0057] The following describes the implementation modes of the present application through specific specific examples. Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification. The present application can also be implemented or applied through other different specific implementation modes. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0058] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present application in a schematic manner. Therefore, only the components related to the present application are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation. The types, quantities, and proportions of the components in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0059] In the following description, a large number of details are explored to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details.

[0060] Figure 1 It is an application scenario diagram of the continuous casting billet length calculation method shown in an exemplary embodiment of the present application. The mold is connected to the continuous casting machine through a vertical section, a bending section, and a segment. In the segment, the continuous casting billet is transported by driving rolls and free rolls; in this embodiment, the segment is pre-divided to obtain 14 segment units, including hardware devices such as an upper frame, a lower frame, a hydraulic cylinder, and a distance measuring sensor. The driving rolls and free rolls are both arranged on the upper frame and the lower frame. Each segment unit includes 1-2 driving rolls, and the others are free rolls; the driving rolls are driven by a driving motor, and an encoder is installed on the driving motor to measure the speed. Distance measuring sensors are arranged on both sides of the entrance and both sides of the exit of each segment unit. The zero point of the distance measuring sensor is adjusted to the roll surface. Therefore, the thickness of the continuous casting billet can be directly obtained through distance measurement.

[0061] As Figure 2 shown, in an exemplary embodiment, the continuous casting billet length calculation method in the continuous casting process at least includes steps S210 to S250, which are introduced in detail as follows, including:

[0062] S210. Obtain the thickness data of the continuous casting billet in each segment unit, the moving speed of the continuous casting billet in the segment unit, the width data of the continuous casting billet in the segment unit, and the tail thickness data of the segment unit located at the tail end of the segment. The segment unit is obtained by dividing the segment; multiple segment units are arranged in sequence along the moving direction of the continuous casting billet;

[0063] In this embodiment, the thickness data of the continuous casting billet in the segment unit is obtained by a ranging sensor arranged on the segment unit; the moving speed of the continuous casting billet in the segment unit is obtained by the encoder on the motor to obtain the rotational speed, and then converted into the moving speed.

[0064] S220. Calculate the volume flux of the continuous casting billet on each segment unit according to the thickness data, width data, and moving speed;

[0065] In step S220, the volume flux is used to measure the volume of the continuous casting billet passing through the segment unit per unit time. The cross-sectional data of the continuous casting billet can be obtained from the thickness data and width data, and then the cross-sectional data is multiplied by the moving data to obtain the volume flux of the continuous casting billet on the segment unit.

[0066] S230. Perform an average operation on the volume fluxes of the continuous casting billets in all segment units to obtain the average volume flux;

[0067] In step S230, when the continuous casting billet moves along the segment, the closer it is to the tail end of the segment (i.e., the end closer to the continuous casting machine), the thinner the continuous casting billet is. Therefore, the thickness of the continuous casting billet in each segment unit is different. In this embodiment, the volume of the continuous casting billet in the segment is represented by the average volume flux for subsequent calculations.

[0068] S240. Calculate the incremental length of the segment unit through which the continuous casting billet passes at the tail end of the segment per unit time according to the average volume flux, width data, and tail-end thickness data;

[0069] In step S240, the cross-sectional data of the continuous casting billet located at the tail end of the segment is calculated by the width data and tail-end thickness data, and then the incremental length of the segment unit through which the continuous casting billet passes at the tail end of the segment per unit time is calculated using the average volume flux. Based on the principle of constant volume of the continuous casting billet, the incremental length per unit time is accurate.

[0070] S250. Accumulate the incremental lengths to obtain the billet length data;

[0071] In step S240, since the incremental length is the length obtained per unit time, accumulation is required to calculate the overall length.

[0072] As Figure 3 shown, in an embodiment of the present application, the process of obtaining the thickness data of the continuous casting billet located in the segment further includes steps S310 to S320, which are introduced in detail as follows:

[0073] S310. Obtain the thickness measurement data at four positions in the segment unit;

[0074] In this embodiment, each sector segment unit is correspondingly provided with 4 ranging sensors, and 4 thickness measurement data are correspondingly collected; the 4 ranging sensors are respectively the left oil cylinder at the entrance of the sector segment unit, the right oil cylinder at the entrance of the sector segment unit, the left oil cylinder at the exit of the sector segment unit, and the right oil cylinder at the exit of the sector segment unit;

[0075] In this embodiment, during the continuous casting production process, the casting blank has a production cross-section of 1650 mm in width and 230 mm in thickness; the data of the 4 ranging sensors are shown in Table 1:

[0076] Table 1. Thickness measurement data table of the sensors

[0078] S320. Perform a weighted average operation on multiple thickness measurement data to obtain the thickness data h i , the thickness data h i The mathematical expression of is:

[0079]

[0080] wherein, is the thickness measurement data of the continuous casting blank on the left side at the entrance of the i-th sector segment unit, is the thickness measurement data of the continuous casting blank on the right side at the entrance of the i-th sector segment unit, is the thickness measurement data of the continuous casting blank on the left side at the exit of the i-th sector segment unit, is the thickness measurement data of the continuous casting blank on the right side at the exit of the i-th sector segment unit.

[0081] In step S320, since 4 thickness measurement data are collected, in order to represent the thickness of the continuous casting blank, the 4 thickness measurement data are weighted averaged to obtain data close to the true thickness; the thickness of the continuous casting blank in each sector segment unit after weighted averaging is shown in Table 2:

[0084] In an embodiment of the present application, the process of calculating the volume flux of the continuous casting blank on the sector segment unit according to the thickness data, width data, and movement speed further includes step S410, which is introduced in detail as follows:

[0085] S410. Multiply the thickness data, width data, and movement speed to obtain the volume flux V i , the volume flux V i The mathematical expression of is:

[0086] V i = hi wv i (2)

[0087] where w is the width data of the continuous casting billet on the i-th segment unit, and h i is the thickness data of the continuous casting billet on the i-th segment unit, and v i is the moving speed of the continuous casting billet on the i-th segment unit.

[0088] In this embodiment, the volume fluxes of the continuous casting billets in each segment unit are shown in Table 3:

[0089] Table 3. Data table of the volume fluxes of the continuous casting billets in each segment unit

[0090]

[0091]

[0092] As Figure 4 shown, in an embodiment of the present application, in the process of averaging the volume fluxes to obtain the average volume flux, steps S510 to S520 are further included, which are introduced in detail as follows:

[0093] S510. Remove the volume flux with the largest value and the volume flux with the smallest value from the n volume fluxes;

[0094] In this embodiment, before calculating the average value of the volume fluxes, it is also necessary to discard the volume flux data with too large volume flux deviation in the segment unit, and then calculate the average value of the remaining volume fluxes.

[0095] S520. Calculate the average value of the remaining n - 2 volume fluxes to obtain the average volume flux Average volume flux The mathematical expression is:

[0096]

[0097] where n is the number of segment units, and V i is the volume flux of the continuous casting billet on the i-th segment unit.

[0098] In this embodiment, segment unit 1 and segment unit 10 are discarded, and then the average value of the volume fluxes of the remaining segment units is calculated. The calculation result is 8632700.8 mm 3 / s.

[0099] In an embodiment of the present application, the mathematical expression of the incremental length Δl is:

[0100]

[0101] Among them, is the tail-end thickness data, is the average volume flux, w is the width data, and t is the unit time.

[0102] In this embodiment, after calculation, the tail-end thickness data has a value of 233.05 mm, the unit time t is taken as 1 s, and actually the cross-sectional area corresponding to the upper continuous casting billet is the average volume increase of the continuous casting billet within 1 s. Dividing the average volume by the cross-sectional area gives the incremental length.

[0103] In an embodiment of the present application, the incremental lengths are accumulated to obtain the billet length data, including:

[0104] As Figure 5 shown, in an embodiment of the present application, the process of accumulating the incremental lengths to obtain the billet length data further includes steps S710 to S720, which are introduced in detail as follows:

[0105] S710. Obtain the continuous casting billet length data of the previous calculation cycle;

[0106] In this embodiment, a calculation cycle is the same as the unit time, both being 1 s. Calculation is performed every 1 s to obtain the incremental length, which is continuously accumulated into the continuous casting billet length data. Therefore, to obtain the complete continuous casting billet length data, in addition to the incremental length of the current calculation cycle, the continuous casting billet length data of the previous calculation cycle is also required.

[0107] S720. Add the incremental length obtained in the current calculation cycle to the continuous casting billet length of the previous calculation cycle to obtain the billet length data l t of the current cycle. The mathematical expression for the billet length data l t of the current cycle is:

[0108] l t = l t-1 + Δl (5)

[0109] where l t-1 is the continuous casting billet length of the previous calculation cycle, and Δl is the incremental length.

[0110] In step S720, for example, if the billet length data l t of the previous calculation cycle is 12500 mm and the incremental length is 22.45 mm, then the billet length of this calculation cycle is 12522.45 mm.

[0111] As Figure 6As shown, in an embodiment of the present application, the process of obtaining the end thickness data further includes steps S810 to S820, which are introduced in detail as follows:

[0112] S810. Obtain two thickness measurement data of the continuous casting billet at the end of the segment unit located at the end of the sector segment;

[0113] In this embodiment, the segment unit located at the end of the sector segment is the segment unit closest to the continuous caster. At the end of this segment unit closest to the continuous caster, the thickness of the continuous casting billet is measured by two distance measuring sensors preset at this end. The continuous casting billet at this place is the thinnest, so the thickness data is the smallest.

[0114] S820. Calculate the average value of the two thickness measurement data of the continuous casting billet at the end of the segment unit located at the end of the sector segment to obtain the end thickness data End thickness data The mathematical expression is:

[0115]

[0116] Where is one of the thickness measurement data of the continuous casting billet at the end of the segment unit located at the end of the sector segment, is the other thickness measurement data of the continuous casting billet at the end of the segment unit located at the end of the sector segment.

[0117] In step S820, is 233.00 mm, is 233.13 mm, and the obtained end thickness is approximately 233.065 mm. For the convenience of calculation, 233.05 mm is directly taken.

The present application calculates the volume flux of the continuous casting billet on the segment, and then calculates the billet length data according to the volume flux and the cross-sectional data of the billet at the end of the segment, making the billet length data more accurate.

[0119] The present application also provides a system for calculating the length of a continuous casting billet in the continuous casting process. The system includes:
