Description

Technical Field

[0001] This application relates to the field of automatic control technology for rolling processes, and in particular to a method and related equipment for controlling the width of the head and tail of electrical steel. Background Technology

[0002] Currently, in the roughing process of hot-rolled strip, the use of large vertical roll side pressure width adjustment technology can reduce the online width adjustment amount of the continuous casting machine and reduce the variety of slab widths. However, the large side pressure of the vertical roll mill causes width defects over a considerable length range at the head and tail of the slab. To avoid this situation, short stroke control (SSC) is implemented at the head and tail of the strip in the hot rolling process. The vertical roll is set with different reduction and roll gap values ​​at the head and tail of the slab compared to the middle of the slab.

[0003] However, due to the influence of different steel grades, specifications, and incoming material widths, different short-stroke control parameters must be used in actual production to meet the width requirements of different strip specifications. This necessitates continuous adjustment and improvement of the short-stroke control parameters based on actual conditions, requiring a quick and effective parameter modification tool to ensure timely modification of control parameters during production to achieve good width control. Currently, there is no suitable method to solve the above problems. Therefore, it is necessary to propose a method for controlling the width of the beginning and end of electrical steel strips to at least solve some of the aforementioned issues.

[0040] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0041] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0042] To improve the yield of the silicon steel production line, the equipment was upgraded and modified. A guide belt unit was added between the CP and ZR units, reducing the head and tail cutting range of hot-rolled electrical steel from the original 10m at the head and 10-15m at the tail to within 5m at the head and 2m at the tail. The cutting loss per coil of electrical steel was reduced by nearly 15m, with an average cutting loss of 280kg-300kg, thereby significantly improving the yield of the silicon steel production line.

[0043] Due to the upgrade of equipment in the silicon steel mill, the length of the lost ladle at the ZR mill inlet has been reduced by approximately 5 meters. After the change in the silicon steel production process, the excessively wide ends of the hot-rolled electrical steel scrape against the guide rolls of the mill, causing edge breakage and, in severe cases, even the risk of strip breakage. This was not the case under the previous production conditions. This places higher quality demands on the width control of hot-rolled electrical steel, requiring that the width of the first 5-10 meters of the finished hot-rolled product exceed the overall width by within 20 mm (the first 5 meters of silicon steel needs to be cut off).

[0044] The width of finished hot-rolled electrical steel products is generally oversized by about 40mm within the first 10m, and the pass rate for those oversized by ≤20mm is very low. In order to meet the needs of users to improve yield and reduce potential customer complaints, it is urgent to improve the control accuracy of the width of the beginning and end of electrical steel products.

[0045] Please see Figure 1 This is a flowchart illustrating a method for controlling the width of the head and tail of electrical steel, provided in an embodiment of this application. Specifically, it may include:

[0046] S110. Obtain product component identification results;

[0047] For example, obtaining product composition identification results is to determine the specific chemical components and their proportions contained in the product. For electrical steel, the product composition identification results include the content of major elements such as iron, silicon, and aluminum, as well as the types and amounts of impurity elements present. This compositional information is crucial for determining whether a product is electrical steel and for selecting a specific production control mode.

[0048] S120. Classify the product composition identification results according to the finished product size and rough rolling passes to obtain classification labels;

[0049] For example, finished product size refers to the final size specification of a product after production. This can include measurements of dimensions such as length, width, and thickness. Different finished product sizes may correspond to different product applications and market demands. For instance, larger sizes of electrical steel may be used in the manufacture of large transformers, while smaller sizes may be suitable for small electrical equipment.

[0050] By considering the finished product dimensions, products with similar dimensional characteristics can be grouped together. This facilitates more targeted management and control during the production process, such as developing specific processing techniques and selecting appropriate equipment and tools.

[0051] Roughing passes are a crucial step in the steel production process. During roughing, the steel billet undergoes multiple rolling passes, gradually reducing its thickness and improving its internal structure. Different roughing passes can impact the performance and quality of the product.

[0052] For example, more roughing passes may result in a more uniform microstructure and more stable properties in the product. Classifying product composition based on the number of roughing passes allows products that have undergone similar roughing processes to be grouped together. This helps analyze the impact of different roughing passes on product composition and properties, thereby optimizing the production process.

[0053] Classifying product composition based on finished product size and roughing passes allows for a better understanding and management of product diversity, providing a basis for decision-making in the production process and improving production efficiency and product quality.

[0054] S130. Obtain the control parameters for the width of the electrical steel head and tail according to the classification identifier;

[0055] For example, the classification identifier is obtained by classifying the product composition based on the finished product size and roughing passes. Its main function is to distinguish and classify different types of products so that the corresponding control parameters and process requirements can be quickly and accurately found in subsequent production processes. The corresponding electrical steel head and tail width control parameters are read based on the classification identifier. These parameters include a first width compensation coefficient, a second width compensation coefficient, a first width reduction compensation coefficient, a second width reduction compensation coefficient, and a head and tail width control length coefficient.

[0056] S140. Control the width of the head and tail of the electrical steel according to the aforementioned head and tail width control parameters.

[0057] For example, the width of the head and tail of the electrical steel is controlled according to the head and tail width control parameters obtained above.

[0058] In summary, the head and tail width control method for electrical steel proposed in this application improves the accuracy of head and tail width control and reduces severe local over-width at the head by using a head and tail width control mode. This significantly improves the yield of silicon steel production lines and effectively prevents accidents such as scrap steel caused by the coiling side guide plate jamming when the head is severely over-width.

[0059] In some examples, the step of obtaining product ingredient identification results includes:

[0060] Obtain product information;

[0061] The product information is analyzed and identified to obtain the product component identification results.

[0062] For example, product information is acquired. This product information is then studied and analyzed to determine the components present in the product. After the analysis and identification process, the product component identification results are obtained.

[0063] In some examples, the steps following the acquisition of product ingredient identification results include:

[0064] If the product composition identification result is electrical steel, activate the electrical steel head and tail width control mode;

[0065] When the electrical steel head and tail width control mode is activated, the product composition identification results are classified according to the finished product size and roughing pass to obtain a classification label.

[0066] For example, if chemical analysis or spectral analysis determines that a product contains a specific proportion of silicon and iron, and meets the composition standards for electrical steel, then the product can be identified as electrical steel. Based on this identification result, a head-and-tail width control mode for electrical steel can be selected for production control. After this head-and-tail width control mode is activated, the product composition identification results, based on factors such as the finished product size and roughing passes, are categorized to obtain a classification identifier. This identifier can be used to distinguish different types of electrical steel products, enabling more targeted head-and-tail width control in the future. Specifically, the classification of the product composition identification results based on finished product size and roughing passes includes:

[0067] For classifying electrical steel according to specifications and pass / fail number, the algorithm function is: f2(a1,a2,...,a i ,b1,b2,...,b j c1, c2, ..., c j ,d n ), where: a1, a2, ..., a i The finished thickness of the product, b1, b2, ..., b j Let c1, c2, ..., c be the finished width of the product. j For roughing passes, d n Here, n is the category identifier, i, j, and n are positive integers;

[0068] In some examples, the step of controlling the width of the electrical steel head and tail according to the electrical steel head and tail width control parameters includes:

[0069] The electrical steel head and tail width control curve function is calculated based on the aforementioned electrical steel head and tail width control parameters.

[0070] The width of the electrical steel head and tail is controlled according to the aforementioned electrical steel head and tail width control curve function.

[0071] For example, firstly, calculations are performed based on the head and tail width control parameters of the electrical steel to obtain a curve function that describes the head and tail width control law of the electrical steel. Then, this head and tail width control curve function is used to actually control the head and tail width of the electrical steel to ensure that the head and tail width of the electrical steel product meets the production requirements.

[0072] In some examples, the electrical steel head and tail width control curve function is expressed as:

[0073]

[0074] Among them, A trim To control the opening degree with short stroke, B shaperFor arrays related to pass number and size, C length The length is controlled by the width at the beginning and end.

[0075] For example, the electrical steel head and tail width control curve function can be used to describe the pattern of electrical steel head and tail width control under different conditions. By adjusting the parameters and variables in the function, precise control of the electrical steel head and tail width can be achieved.

[0076] In some examples, the short-stroke control opening is expressed as:

[0077] A trim =W trim +S trim (2);

[0078] Among them, W trim =P width ×P1+(P fix -P width )×P2 / P fix P width For calculating the width of each pass in rough rolling, P fix This refers to the fixed width value designed based on the length of the roughing mill work roll. P1 is the first width compensation coefficient, and P2 is the second width compensation coefficient. S trim =D width ×D1+(W fix -D width )×D2 / D fix D width D is the width reduction calculated for each pass of rough rolling. fix This refers to the fixed width reduction amount designed for each pass based on equipment capacity. D1 is the compensation coefficient for the first width reduction amount, and D2 is the compensation coefficient for the second width reduction amount.

[0079] For example, the short-stroke control opening can be calculated more accurately using equation (2), thus providing a basis for controlling the width of the electrical steel head and tail.

[0080] In some examples, the head and tail width control length is expressed as:

[0081]

[0082] Among them, D width D is the width reduction calculated for each pass of rough rolling. dia The diameter of the current vertical roller, C1 is the head and tail width control length coefficient.

[0083] In some examples, by using equation (3), the appropriate head and tail width control length can be calculated according to different production conditions and requirements, so as to achieve effective control of the head and tail width of electrical steel.

[0084] The present invention will be described in detail below with reference to the embodiments, but these should not be construed as limiting the scope of protection of the present invention.

[0085] Example:

[0086] This application was applied to a hot rolling line in a steel plant. Based on the finished dimensions and roughing passes of the electrical steel, the product composition identification results were classified, resulting in eight specification groups. The scheme is shown in Table 1.

[0087]

[0089] Based on the experimental classification of electrical steel produced daily, the following parameters are configured for the head and tail width control of the electrical steel in 8 categories:

[0097] After implementing the control method described in this application, the head and tail width control accuracy of electrical steel is improved through the head and tail width control mode, reducing the severe local overwidth at the head. This significantly improves the yield of silicon steel production lines and effectively prevents accidents caused by the coiling side guide plate clamping and resulting in scrap steel due to severe local overwidth at the head. Table 5 shows the comparison results of 15,000 steel pieces before and after applying the method of this invention after the significant improvement in the head and tail width accuracy of electrical steel.
