After summarizing various quality information, it is passed to the shearing unit for trimming and coiling according to the conventional production sequence. After the shearing unit completes the cutting, the finished coil is packaged and put into storage.

[0040] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0041] In order to better understand the application scheme of the present invention, the implementation reasons of the present invention are first introduced here. Figure 1 As shown in the figure, the conventional cold rolling process of electrical steel includes rolling → continuous annealing → shearing → packaging. The raw material coil used in the annealing unit is a chilled coil, which is formed into an annealed coil after continuous annealing. Figure 1 According to the conventional process, all annealed coils need to enter the shearing unit for shearing and then enter the packaging unit to be packaged into finished coils and delivered to downstream users.

[0042] However, at present, some users do not need the upstream production line to cut the annealed coils, but need to cut the annealed coils by themselves. This means that the rolling process of the upstream production line needs to identify which annealed coils can be directly packaged as finished products, and which annealed coils still need to be cut before being packaged as finished products.

[0043] Based on this, the present invention provides a method for determining the process flow of a steel coil, such as Figure 2 As shown, the method mainly includes the following steps:

[0044] S210, determining a first slitting determination result of the chilled coil according to a transverse thickness difference of the chilled coil, a longitudinal thickness difference of the chilled coil, and a surface appearance of the chilled coil; the first slitting determination result is used to indicate whether the chilled coil needs to be sheared in an annealing process.

[0045] The raw material of the continuous annealing unit (continuous annealing unit) is a chilled coil, which is formed into an annealed coil after annealing. The transverse thickness difference, longitudinal thickness difference and surface appearance of the chilled coil and the annealed coil are consistent. Therefore, in order to shorten the time for determining the process flow of the steel coil, before continuous annealing, the transverse thickness of the chilled coil at different positions and the longitudinal thickness at different positions can be collected by thickness measuring equipment, and the transverse thickness difference can be determined according to the transverse thickness at different positions, and the longitudinal thickness difference can be determined according to the longitudinal thickness at different positions, and the surface appearance of the chilled coil can be determined by image recognition equipment.

[0046] When using image recognition equipment to determine the surface appearance of a cold-hardened coil, it is necessary to collect the current appearance image of the cold-hardened coil, use the image recognition algorithm to compare the current appearance image with the pre-stored appearance defect image, and finally determine whether there are abnormal appearance features on the surface of the cold-hardened coil. For example, abnormal appearance features may include: hole features, defect features (such as scratches, peeling), etc. Then, when there are abnormal appearance features, the surface appearance is determined to be an abnormal appearance type; if there are no abnormal appearance features, the surface appearance is determined to be a normal appearance type.

[0047] Then, the first slitting determination result of the chilled coil is determined according to the transverse thickness difference of the chilled coil, the longitudinal thickness difference of the chilled coil and the surface appearance of the chilled coil. The first slitting determination result is used to indicate whether the chilled coil needs to be sheared in the annealing process.

[0048] For example, if the first slitting judgment result includes the judgment result that the head and / or tail of the chilled coil need to be sheared, since it is the head and / or tail that need to be sheared, then in the annealing process, the head and / or tail of the chilled coil can be sheared first.

[0049] Therefore, in one embodiment, after determining the first slitting determination result of the chilled coil according to the transverse thickness difference of the chilled coil, the longitudinal thickness difference of the chilled coil and the surface appearance of the chilled coil, the method further includes:

[0050] In the annealing process, if it is determined in the first slitting judgment result that the chilled coil head and / or the chilled coil tail have an unqualified plate difference, an abnormal longitudinal thickness of the chilled coil head and / or the chilled coil tail, or an unqualified appearance of the chilled coil head and / or the chilled coil tail, the chilled coil head and / or the chilled coil tail are sheared in the annealing process.

[0051] However, if the first slitting judgment result includes the judgment result that the middle part of the chilled coil needs to be sheared, since the running time of the chilled coil in the annealing furnace is very short (generally only 3 to 5 minutes), the middle part of the chilled coil cannot be sheared in the annealing process, and the transverse thickness difference of the annealing coil cannot be detected by the transverse thickness difference measuring equipment. Therefore, the transverse thickness difference judgment result of the chilled coil in the first slitting judgment result will be inherited to the annealing process and then converted into the transverse thickness difference of the annealing coil (there is no need to re-judge the transverse thickness difference of the annealing coil in the annealing process). The longitudinal thickness difference of the annealing coil and the surface appearance of the annealing coil need to be re-judged and confirmed in the annealing process to provide a reference for the subsequent determination of the annealing mark.

[0052] S211, in the process of annealing the chilled coil to form an annealed coil, determining a second slitting judgment result of the annealed coil according to a transverse thickness difference of the annealed coil, a longitudinal thickness difference of the annealed coil, and a surface appearance of the annealed coil.

[0053] In order to improve the accuracy of determining the process flow, in the process of annealing the cold hard coil to form the annealed coil, it is also necessary to determine the second slitting judgment result of the annealed coil based on the transverse thickness difference of the annealed coil, the longitudinal thickness difference of the annealed coil and the surface appearance of the annealed coil.

[0054] The second slitting determination result includes: a slitting determination result of a transverse thickness difference of the annealed coil, a slitting determination result of a longitudinal thickness difference of the annealed coil, and a slitting determination result of a surface appearance of the annealed coil; the second slitting determination result of the annealed coil is determined according to the transverse thickness difference of the annealed coil, the longitudinal thickness difference of the annealed coil, and the surface appearance of the annealed coil, including:

[0055] If it is determined that the transverse thickness difference of the annealed coil meets the preset first threshold range, the transverse thickness difference slitting judgment result of the annealed coil is determined to be qualified for the same plate difference;

[0056] If it is determined that the longitudinal thickness difference of the annealed coil meets the preset second threshold range, then the longitudinal thickness difference slitting judgment result of the annealed coil is determined to be normal in longitudinal thickness; and

[0057] If it is determined that the surface appearance of the annealed coil does not have abnormal appearance features, then the annealed coil surface appearance slitting judgment result is determined to be qualified in appearance.

[0058] S212, determining an annealing mark according to the second slitting determination result; the annealing mark is used to indicate whether the annealing coil needs to be sheared; obtaining an actual width of the annealing coil, and determining a trimming mark according to the actual width.

[0059] After the second cutting determination result is determined, in one embodiment, determining the annealing mark according to the second cutting determination result includes:

[0060] If the annealing coil transverse thickness difference slitting judgment result is determined to be qualified for the same plate difference, the annealing coil longitudinal thickness difference slitting judgment result is determined to be normal for the longitudinal thickness, and the annealing coil surface appearance slitting judgment result is determined to be qualified for the surface appearance, then the annealing mark is determined to be the finished product packaging mark.

[0061] In one embodiment, determining the annealing mark according to the second cutting determination result includes:

[0062] If the annealed coil transverse thickness difference cut judgment result is determined to be unqualified; or

[0063] If the longitudinal thickness difference of the annealed coil is determined to be abnormal; or

[0064] If the annealing coil surface appearance slitting judgment result is determined to be unqualified in appearance, the annealing mark is determined to be the annealing shear mark.

[0065] Specifically, if it is determined that the transverse thickness difference of the annealed coil meets the preset first threshold range, the transverse thickness difference slitting judgment result of the annealed coil is determined to be qualified for the same plate difference; if it is determined that the transverse thickness difference of the annealed coil meets the preset second threshold range, the longitudinal thickness difference slitting judgment result of the annealed coil is determined to be normal for the longitudinal thickness; if it is determined that there is no abnormal appearance feature on the surface appearance of the annealed coil, the surface appearance slitting judgment result of the annealed coil is determined to be qualified for appearance, and the annealing mark is determined to be the finished product packaging mark, indicating that the annealed coil can be directly packaged. Among them, the first threshold range and the second threshold range can be specifically set according to the type of steel, and are not limited here.

[0066] On the contrary, if the annealing coil transverse thickness difference slitting judgment result is determined to be unqualified for the same plate difference, or the annealing coil longitudinal thickness difference slitting judgment result is determined to be abnormal longitudinal thickness, or the annealing coil surface appearance slitting judgment result is determined to be unqualified for appearance, then the annealing mark is determined to be the annealing shear mark, indicating that the defects of the annealing coil need to be sheared before entering the packaging process.

[0067] In practical applications, the annealing and shearing mark and the finished product packaging mark can be represented by different characters, for example, the annealing and shearing mark can be 0, and the finished product packaging mark can be 1; other identifiers can also be used for identification, which is not limited here.

[0068] In addition, if the annealing coil transverse thickness difference slitting judgment result is determined to be unqualified with the same plate difference, the specific position of the unqualified with the same plate difference will be given at the same time (for example, 0 to 300 meters). When the annealing coil longitudinal thickness difference judgment result is abnormal longitudinal thickness, the abnormal position will also be output (for example, 0 to 200 meters). When the surface appearance slitting judgment result is unqualified appearance, the position of the abnormal appearance feature of the annealing coil will also be output (for example, 2950m to 2955m). In addition, if the head or tail of the cold hard coil is sheared off due to defects during the annealing process, the total length of the steel coil will change. Therefore, the above-mentioned abnormal position information of the annealing coil will be automatically converted at the same time, so that the unqualified strip can be sheared off later.

[0069] It should be noted that when the cold hard coil is annealed to form an annealed coil, the actual width of the annealed coil will also affect the process flow of the annealed coil. For example, if the actual width is the finished product width, the process flow can be the packaging process; if the actual width is greater than the finished product width (the middle width or the untrimmed width), the process flow is the shearing process.

[0070] Based on this, the actual width needs to be obtained and the trimming mark is determined according to the actual width; the trimming mark can also be used to determine whether the annealing coil needs to be sheared.

[0071] In one embodiment, determining the trimming mark according to the actual width includes:

[0072] If it is determined that the actual width is the finished product width, the trimming mark is determined to be the first mark corresponding to the unnecessary trimming; the first mark is the finished product mark;

[0073] If it is determined that the actual width is the middle width or the untrimmed width, the trimming mark is determined to be the second mark corresponding to the required trimming, and the second mark is the unfinished product mark.

[0074] In one embodiment, determining the actual width as the finished product width includes:

[0075] Find the corresponding order width according to the coil number of the annealed coil;

[0076] If it is determined that the difference between the actual width and the order width is within a first threshold range, the actual width is determined to be the finished product width.

[0077] In one implementation, determining the actual width as the intermediate width includes:

[0078] If it is determined that the difference between the actual width and the order width is within the second threshold range, the actual width is determined to be the middle width; the second threshold range is greater than the first threshold range.

[0079] Specifically, each steel coil has a unique steel coil number. For the same steel coil, the steel coil numbers of the cold-hardened coil and the annealed coil are the same. Therefore, the corresponding order width (the steel coil width required by the customer) can be queried by the steel coil number of the annealed coil. If the difference between the actual width and the order width is within the first threshold range [0, 1.5mm), it means that the actual width is the finished product width. If the difference between the actual width and the order width is within the second threshold range [1.5mm, 10mm), it means that the actual width is the middle width (the annealed coil has been trimmed but not cut to the order width); if the difference between the actual width and the order width is greater than 10mm, it means that the annealed coil has not been trimmed and the actual width is the untrimmed width.

[0080] When it is determined that the actual width is the finished product width, the trimming mark may be the first mark, indicating that trimming of the annealed coil is not required.

[0081] When it is determined that the actual width is the middle width or the untrimmed width, the trimming mark may be a second mark, indicating that the annealed coil needs to be trimmed.

[0082] S213, obtaining a manual comprehensive determination result, and determining the process flow of the annealing coil according to the annealing mark, the trimming mark and the manual comprehensive determination result.

[0083] In order to improve the accuracy of determining the process flow of the steel coil, it is also necessary to obtain the results of manual comprehensive determination, and then determine the process flow of the annealed coil based on the annealing mark, trimming mark and manual comprehensive determination results.

[0084] The result of the manual comprehensive judgment is determined based on manual experience and then input through the human-machine interface. For example, if the result of the manual comprehensive judgment is a qualified product, the staff will input "qualified" in the corresponding position of the human-machine interface; if the result of the manual comprehensive judgment is a usable material, the staff will input "usable material" in the corresponding position of the human-machine interface, indicating that the result of the manual comprehensive judgment is unqualified. Among them, only the two words "qualified" in the manual comprehensive judgment result indicate that the manual comprehensive judgment result is a qualified product.

[0085] In one embodiment, the process flow of the annealed coil is determined according to the annealing mark, the trimming mark and the manual comprehensive determination result, including:

[0086] If the annealing mark is determined to be the finished product packaging mark, the trimming mark is determined to be the first mark, and the manual comprehensive determination result is determined to be a qualified product, the process flow of the annealed coil is determined to be the finished product packaging process.

[0087] In one embodiment, the process flow of the annealed coil is determined according to the annealing mark, the trimming mark and the manual comprehensive determination result, including:

[0088] If the annealing mark is determined to be the annealing shear mark; or,

[0089] If the trimming mark is determined to be the second mark; or,

[0090] If the result of the manual comprehensive judgment is determined to be a defective product, the process flow of the annealing coil is determined to be a shearing process.

[0091] Specifically, only when the manual comprehensive judgment result is a qualified product, the trimming mark is the first mark corresponding to the unnecessary trimming, and the annealing mark is the finished product packaging mark, it is determined that the annealed coil can be directly packaged, and the process flow is the packaging process.

[0092] However, if the annealing mark is the annealing shear mark, or the trimming mark is the second mark corresponding to the trimming required, or the manual comprehensive judgment result is a defective product, it is determined that the annealed coil needs to be sheared before packaging, then the process flow is determined to be the shearing process.

[0093] For example, the manual comprehensive judgment result, annealing mark, trimming mark, transverse thickness difference cutting judgment result, longitudinal thickness difference cutting judgment result and surface appearance cutting judgment result can be shown in Table 1:

[0094] Table 1

[0095]

[0096] Taking the annealed coil A as an example, the manual comprehensive judgment result is that it is a qualified product, the annealing mark is the finished product packaging mark, and the trimming mark is the first mark, so the process flow of the annealed coil is determined to be the packaging process.

[0097] Taking the annealed coil B as an example, the manual comprehensive judgment result is a qualified product, the annealing mark is a finished product annealing shear mark, and the trimming mark is a second mark, so the process flow of the annealed coil is determined to be a shearing process.

[0098] In this way, by associating the surface defects, thickness information, hole information and width information of the steel coil, the process flow of the annealing coil can be automatically determined. That is, the present invention can determine the annealing mark according to the surface defects and thickness information of the chilled coil. Since the transverse thickness difference, longitudinal thickness difference and surface appearance of the chilled coil and the annealing coil are consistent, the annealing mark can indicate whether the annealing coil needs to be sheared, and then the process flow of the annealing coil is determined by combining the trimming mark and the manual comprehensive judgment result, so that the annealing coil that does not meet the packaging conditions can be efficiently transferred to the shearing unit, and the annealing coil that meets the packaging conditions can be directly transferred to the packaging unit for packaging across the shearing unit, thereby improving the operation efficiency of the production line.

[0099] Based on the same inventive concept as in the above-mentioned embodiment, this embodiment also provides a device for determining the process flow direction of a steel coil, such as Figure 3 As shown, the device comprises:

[0100] a first determination unit 31, configured to determine a first slitting determination result of the chilled coil according to a transverse thickness difference of the chilled coil, a longitudinal thickness difference of the chilled coil, and a surface appearance of the chilled coil; the first slitting determination result is used to indicate whether the chilled coil needs to be sheared in an annealing process;

[0101] A second determination unit 32 is used to determine a second slitting determination result of the annealing coil according to a transverse thickness difference of the annealing coil, a longitudinal thickness difference of the annealing coil, and a surface appearance of the annealing coil during annealing of the chilled coil to form the annealing coil;
