Description

[0002] The continuous casting process includes the cooling and solidification process of molten steel. In the cooling and solidification process of the continuous casting billet, the secondary cooling water cooling characteristic is an important link of the continuous cooling, and has a significant influence on the quality of the billet. The cooling characteristic will affect the control of the surface crack and the internal performance of the billet.

[0003] For slab continuous casting, since the width of the billet is wide, a plurality of nozzles are usually arranged in a row (along the width direction of the billet) to spray water. If the selection and arrangement design of the nozzles are unreasonable, the water distribution will be unreasonable, and then the cooling of the billet in the width direction will be uneven, the temperature difference at different positions in the width direction of the billet is large, and cracks are prone to occur during straightening, which affects the quality of the billet. It can be seen that the water distribution of the secondary cooling water is particularly important for the slab continuous casting process.

[0004] In actual production, whether the water distribution of the secondary cooling water is uniform is usually judged by measuring the temperature of the billet or observing the color of the surface of the billet with the naked eye, and the accuracy is not high. Therefore, a higher accuracy technology is needed to determine the distribution of the nozzles on the secondary cooling production line of the continuous casting, and to improve the uniformity of the water distribution of the secondary cooling water.

[0052] The embodiment of the present application provides a method for determining distribution of continuous casting secondary cooling nozzles, and solves the technical problem that in the prior art, whether the secondary cooling water distribution is uniform is determined by measuring the temperature of a casting blank or observing the color of the surface of the casting blank by naked eyes, and the accuracy is not high.

[0053] To solve the above technical problem, the technical scheme of the embodiment of the present application is as follows:

[0054] The method comprises the following steps: acquiring water distribution corresponding to M types of nozzles under the same spraying condition; M is a positive integer; according to the width range of a casting blank adapted to a target secondary cooling production line and the M types of nozzles, N arrangement modes are formed; N is a positive integer; according to the water distribution corresponding to each nozzle in each arrangement mode and the relative position relationship between the nozzles, the superimposed water distribution corresponding to each arrangement mode on the target secondary cooling production line is determined; and according to the superimposed water distribution corresponding to each arrangement mode and a target water distribution feature, a target arrangement mode is selected from the N arrangement modes, so as to be used for the design and production of the target secondary cooling production line.

[0055] In the embodiment, the water distribution corresponding to each of the M types of nozzles is acquired first, then according to the width range of a casting blank adapted to a target secondary cooling production line and the M types of nozzles, N arrangement modes are formed, the superimposed water distribution corresponding to each arrangement mode is determined, and a target arrangement mode meeting the target water distribution feature is selected from the N arrangement modes as the target arrangement mode, so as to be used for the design and production of the target secondary cooling production line. It can be seen that, on the one hand, the embodiment can quickly select multiple target arrangement modes meeting the target water distribution feature, and on the other hand, the arrangement mode can be selected at will from the multiple target arrangement modes in the design and production process of the target secondary cooling production line, so that the arrangement mode of the nozzles on the secondary cooling production line is more consistent with the characteristics of the production line itself, the accuracy of determining the distribution of the nozzles on the continuous casting secondary cooling production line is improved, and the consistency with the actual continuous casting process is improved, the transverse cooling uniformity of the continuous casting blank is improved, the probability of occurrence of quality defects such as cracks of the continuous casting blank is reduced, and the quality of the continuous casting blank is improved.

[0056] In order to better understand the above technical scheme, the above technical scheme will be described in detail in combination with the drawings of the specification and specific embodiments.

[0057] Firstly, the term "and / or" appearing in the present text only describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in the present text generally represents an "or" relationship between the front and rear associated objects.

[0058] The embodiment provides a method for determining a distribution of a continuous casting secondary cooling nozzle as shown in Figure 1 The method comprises steps S11-S14.

[0059] In step S11, the water distribution of M different types of nozzles under the same spraying condition is obtained; M is a positive integer.

[0060] In step S12, N arrangement modes are formed according to the width range of the adapted casting blank on the target secondary cooling line and the M different types of nozzles; N is a positive integer.

[0061] In step S13, the superimposed water distribution of each arrangement mode on the target secondary cooling line is determined according to the water distribution of each nozzle in each arrangement mode and the relative position relationship between the nozzles.

[0062] In step S14, the target arrangement mode is selected from the N arrangement modes according to the superimposed water distribution of each arrangement mode and the target water distribution characteristics, so as to be used for the design and production of the target secondary cooling line.

[0063] In step S11, the water distribution of M different types of nozzles under the same spraying condition is obtained; M is a positive integer.

[0064] The spraying condition includes the water pressure, air pressure and spraying distance provided by the nozzle. The spraying distance here refers to the distance between the water sprayed by the nozzle and the water receiving plane. In actual operation, the water receiving plane is the surface of the casting blank on the continuous casting secondary cooling line.

[0065] The water distribution of different types of nozzles under the same spraying condition is different, for example, the water distribution of some nozzles involves a wider range, the water distribution of some nozzles involves a narrower range, the water area shape of some nozzles is a circle, and the water area shape of some nozzles is an ellipse.

[0066] Figure 2 As shown in the figure, the water distribution diagram formed by the nozzle of a certain type extending from the nozzle center (i.e. the horizontal axis 0) to the edge of the region, from Figure 2As can be seen from the water volume distribution column chart, the water volume is the largest at the center of the nozzle, and the farther the distance from the center of the nozzle, the smaller the water volume. Although different types of nozzles have different water volume distribution, the basic feature is that the water volume is the largest at the center of the nozzle, and the farther the distance from the center of the nozzle, the smaller the water volume. The embodiment only takes the water volume distribution column chart as an example to illustrate the water volume distribution of the nozzle. Figure 2

[0067] M can be determined according to the type of the nozzle actually selected, or can be determined according to the actual demand of the continuous casting secondary cooling line.

[0068] Regarding step S12, N arrangement modes are constituted according to the width range of the slab adapted to the target secondary cooling line and M different types of nozzles; N is a positive integer.

[0069] Different widths of slabs can be cooled on the same secondary cooling line, and the narrowest width of the slab and the widest width of the slab that can be cooled are determined according to the design demand of the target secondary cooling line, and the width range of the slab can be constituted according to the narrowest width of the slab and the widest width of the slab.

[0070] A row of nozzles is arranged along the transmission direction of the slab on the same secondary cooling line, and each row of nozzles is arranged along the width direction of the slab (the width direction is perpendicular to the transmission direction). The number and arrangement position of the nozzles in different rows can be selected and set according to actual conditions.

[0071] The N arrangement modes refer to the arrangement mode of each row in N, or the arrangement mode constituted by two adjacent rows in N.

[0072] The types of the nozzles in the same row can be the same or different. In actual operation, the number of types involved in the nozzles in the same row can be determined according to the difficulty of system control. For example, if the processing capacity of the control system of the secondary cooling line is good, a larger number of types of nozzles (such as 3 types or more) can be arranged in a row of nozzles; if the processing capacity of the control system of the secondary cooling line is poor, a smaller number of types of nozzles (such as 1 type or 2 types) can be arranged in a row of nozzles.

[0073] It should be noted that when a row of nozzles has multiple nozzles of different types, the middle line of the secondary cooling line in the width direction is taken as the reference, and the types of the two nozzles on both sides of the middle line and symmetric about the middle line need to be the same. For example, a row of nozzles has 6 nozzles, which are denoted as a1, a2, a3, a4, a5 and a6, then the types of a1 and a6 are the same, the types of a2 and a5 are the same, and the types of a3 and a4 are the same. For another example, a row of nozzles has 5 nozzles, which are denoted as b1, b2, b3, b4 and b5, then b3 is on the middle line, the types of b1 and b5 are the same, and the types of b2 and b4 are the same.

[0074] ​The N arrangement methods include one or more of the following arrangement methods, and by combining the following four methods with the spacing between adjacent nozzles and the different types of nozzles, N arrangement methods can be obtained.

[0075]

Method 1

[0076]

Method 2

[0077]

Method 3

[0078]

Method 4

[0079] Regarding step S13, based on the water distribution of each nozzle in each arrangement and the relative positional relationship between each nozzle, the superimposed water distribution of each arrangement on the target second cooling production line is determined.

[0080] After determining N arrangement methods, the type and number of nozzles in each arrangement method are known. Then, the water volume distribution of each type of nozzle obtained in step S11 can be superimposed to obtain the superimposed water volume distribution corresponding to each arrangement method.

[0081] Specifically, based on the water distribution of each nozzle in each arrangement and the relative positional relationship between each nozzle, the overlapping and non-overlapping water distribution areas of each nozzle can be determined. The water distribution corresponding to the overlapping water distribution areas of each nozzle is superimposed, and the superimposed water distribution is spliced ​​with the water distribution corresponding to the non-overlapping water distribution areas to obtain the superimposed water distribution of each arrangement on the target second cold production line.

[0084] Regarding step S14, according to the superimposed water volume distribution corresponding to each arrangement mode and the target water volume distribution characteristics, a target arrangement mode is selected from the N arrangement modes for the target secondary cooling line design and production.

[0085] The target water volume distribution characteristics include one or more of the following characteristics:

[0086]

Feature One

[0087]

Feature Two

[0088] The division of the middle or edge of the secondary cooling line (or the middle or edge of the casting blank) can be determined according to the actual situation, such as dividing the casting blank into four parts along the width direction, the middle two parts are the middle region, and the remaining two parts are the edge region. Of course, it can also be divided into six parts along the width direction, the middle four parts are the middle region, and the remaining two parts are the edge region.

[0089] The first preset proportion range can be 30%-60%, and the second preset proportion range can be ±15%. That is, the water amount of the edge of the casting blank is 30%-60% of the water amount of the middle, and the water amount fluctuation of the middle of the casting blank cannot exceed ±15% of the average water amount. Generally, the water amount of the edge of the casting blank needs to be low, and the water amount of the middle needs to be balanced.

[0090] According to the target water amount distribution characteristics, each arrangement manner in the N arrangement manners is screened, and the arrangement manner meeting the target water amount distribution characteristics is recorded as a target arrangement manner. Thus, in the target secondary cooling line design and production process, a suitable nozzle distribution manner can be directly selected from the target arrangement manner.

[0091] To sum up, in the embodiment, the water amount distribution of each nozzle of M different types is obtained, N arrangement manners are formed according to the width range of the casting blank adapted to the target secondary cooling line and the M nozzles, the superimposed water amount distribution corresponding to each arrangement manner is determined, and the arrangement manner meeting the target water amount distribution characteristics is screened from the N arrangement manners as the target arrangement manner for the target secondary cooling line design and production. It can be seen that the embodiment can quickly screen multiple target arrangement manners meeting the target water amount distribution characteristics, and can also select an arrangement manner from the multiple target arrangement manners in the target secondary cooling line design and production process, so that the nozzle arrangement manner of the secondary cooling line is more consistent with the characteristics of the line itself, the accuracy of determining the nozzle distribution of the continuous casting secondary cooling line is improved, and the consistency with the actual continuous casting process is improved, the transverse cooling uniformity of the continuous casting blank is improved, the occurrence probability of quality defects such as cracks of the continuous casting blank is reduced, and the quality of the continuous casting blank is improved.

[0092] After obtaining the target arrangement manner, the embodiment can further perform steps S21-S22.

[0093] In step S21, Y original arrangement manners of nozzles on a non-target secondary cooling line on which nozzles have been arranged are obtained; Y is a positive integer.

[0094] In step S22, whether each original arrangement manner needs to be changed is determined according to the water amount distribution corresponding to each original arrangement manner and the target water amount distribution characteristics.

[0095] The foregoing target secondary cooling line can be a line on which nozzles need to be rearranged, or a new line on which nozzles have not been arranged, and the non-target secondary cooling line refers to a line on which nozzles have been arranged.

[0096] For the non-target secondary cooling production line, the original arrangement mode involved can be collected, and the water distribution of each original arrangement mode is analyzed based on the target water distribution characteristics to determine whether the original arrangement mode meets the water distribution characteristics. If it meets, it means that the original arrangement mode can provide good secondary cooling characteristics for the casting blank, and it can not be adjusted; if it does not meet, it means that the original arrangement mode cannot provide good secondary cooling characteristics for the casting blank, and it needs to be adjusted.

[0097] When the original arrangement mode needs to be adjusted, scheme one, or scheme two, or a combination of scheme one and scheme two can be used.

[0098]

Scheme one

[0099] Step S31, when the original arrangement mode needs to be changed, a similar arrangement mode is selected from the target arrangement mode according to the similarity between the original arrangement mode to be changed and the target arrangement mode;

[0100] Step S32, the original arrangement mode is adjusted according to the similar arrangement mode corresponding to the original arrangement mode to be changed.

[0101] The original arrangement mode is compared with various target arrangement modes to determine the similarity between the original arrangement mode and the various target arrangement modes, and the target arrangement mode with the greatest similarity is selected as the similar arrangement mode from the target arrangement modes with a similarity greater than a preset threshold, and the original arrangement mode is adjusted according to the similar arrangement mode. When the similarity between the original arrangement mode and the various target arrangement modes is less than the preset threshold, the target arrangement mode with the greatest similarity can also be selected as the similar arrangement mode, and the original arrangement mode is modified according to the similar arrangement mode.

[0102] It can be seen that the embodiment can modify the nozzle distribution of the already constructed production line (i.e. the old production line) based on the target arrangement mode determined in the foregoing, can improve the accuracy of the water distribution of the old production line under the premise of lower modification cost, and further improve the compliance with the actual continuous casting process, can improve the transverse cooling uniformity of the continuous casting blank, reduce the probability of quality defects such as cracks of the continuous casting blank, and improve the quality of the continuous casting blank.

[0103]

Scheme two

[0104] Step S41, according to the water distribution of each original arrangement mode and the target water distribution characteristics, the defects of the water distribution of each original arrangement mode are determined;

[0105] Step S42, adjusting the water quantity of each nozzle in each original arrangement mode according to the defects of the water quantity distribution corresponding to each original arrangement mode, so that the water quantity distribution of the original arrangement mode after modification meets the target water quantity distribution characteristics.

[0106] According to the target water quantity distribution characteristics, the water quantity distribution corresponding to each original arrangement mode is checked to determine whether the water quantity distribution corresponding to each original arrangement mode has defects, that is, whether there is a difference between the water quantity distribution corresponding to each original arrangement mode and the target water quantity distribution characteristics. If there is a difference, the water quantity of each nozzle in the original arrangement mode is changed without changing the number and type of nozzles in the original arrangement mode, so that the original arrangement mode after adjusting the water quantity matches the target water quantity distribution characteristics.

[0107] As can be seen, the embodiment can also be based on the target water quantity distribution characteristics to reform the nozzle distribution of the already constructed production line (i.e. the old production line). Without replacing the nozzle equipment, the accuracy of the water quantity distribution of the old production line can be improved at a lower reconstruction cost, thereby improving the compliance with the actual continuous casting process, improving the transverse cooling uniformity of the continuous casting billet, reducing the occurrence probability of quality defects such as cracks of the continuous casting billet, and improving the quality of the continuous casting billet.

[0108] After the nozzle distribution determination method provided in the embodiment is used, the nozzle arrangement or nozzle selection of unreasonable water quantity distribution is optimized, and the occurrence probability of the edge cracks of the billet is obviously improved. The average value of the production technical indexes in the three months after the method is used is counted. The temperature difference between the edge temperature of the billet and the intermediate temperature of the billet is reduced from 50-90℃ to 10-40℃, the occurrence probability of the cracks of the billet is reduced from the original 2.55% to 0.50%, the performance of the billet is improved, and the quality of the billet meets the subsequent production and customer demand.
