It should be noted that the described embodiments are only a part of the present application, not all embodiments. In the following description, the "some embodiments" mentioned are only subsets of all possible embodiments, which may be the same or different subsets, and different embodiments may be combined with each other without conflict.

[0025] Figure 1Schematic diagram of a pickling steel rolling method provided in the embodiment of the present application. Figure 1 The pickling steel rolling method provided in the embodiment of the present application may include the following steps 101 to 104:

[0026] Step 101, obtaining a pickled steel rolling transition material according to a first preset rolling parameter configuration, and rolling the pickled steel rolling transition material, wherein the first preset rolling parameter configuration may include a steel billet thickness greater than or equal to 2.5 mm and a steel billet number of 12;

[0027] In some examples, the first preset rolling parameter configuration refers to the preset specific rolling parameters for the steel billets of the pickled steel transition material in order to ensure the smooth start-up and stability of the production process during the pickled steel rolling process, including the thickness of the steel billets, the number of pieces, etc.; at this stage, the selected steel billet thickness range is required to be at least 2.5 mm, and a total of 12 steel billets are selected for rolling. The pickled steel transition material refers to a special steel used to smoothly start the rolling equipment and production line during the pickled steel production process. Its function is to control the initial rolling state to avoid excessive burden on the production line, ensure that the equipment can start smoothly and adapt to subsequent rolling with higher requirements.

[0028] Exemplarily, by selecting steel billets that meet the first preset rolling parameter configuration, such as 12 steel billets with a thickness greater than or equal to 2.5 mm, the rolling of pickled steel transition materials is carried out, thereby ensuring the smooth start-up of the rolling equipment and making full preparations for the subsequent rolling stage; through this configuration, the production line is successfully started while ensuring that the rolling process does not fluctuate violently, thereby improving the stability and efficiency of the subsequent main rolled material production.

[0029] By implementing step 101, excessive deformation and waste in the early stage of rolling can be avoided, while early load fluctuations can be reduced to ensure a smooth start of the rolling process.

[0030] Step 102, obtaining a pickled steel main rolling material according to a second preset rolling parameter configuration, and rolling the pickled steel main rolling material, wherein the second preset rolling parameter configuration may include a steel billet thickness less than or equal to 2.5 mm, and a steel billet number less than or equal to 30;

[0031] In some examples, the second preset rolling parameter configuration refers to a preset rolling parameter for specific needs of the pickled steel main rolling products in order to ensure the smooth progress of the subsequent production stage during the pickled steel production process. The pickled steel main rolling products refer to steel products that enter the formal production stage after preliminary treatment during the pickled steel production process. These steel products are the basis of the final product. After the main rolling, they will be transformed into thinner steel products with a certain strength and surface quality.

[0032] Exemplarily, according to the second preset rolling parameter configuration, a steel billet with a thickness less than or equal to 2.5 mm and a number of steel billet blocks less than or equal to 30 is selected for rolling the pickled steel main rolled product. Through this configuration, the production of the main rolled product can ensure the final formation of high-quality pickled steel while precisely controlling the steel thickness and the number of blocks, thereby improving the efficiency of the production line and the qualified rate of steel.

[0033] By implementing step 102, the thickness (≤2.5mm) and number of blocks (≤30) of the pickled steel main rolled product are precisely controlled, which can ensure that the steel specifications are consistent during the rolling process and effectively avoid the problem of uneven thickness during the rolling process.

[0034] Step 103, obtaining a rebound transition material according to a third preset rolling parameter configuration, and rolling the rebound transition material, wherein the third preset rolling parameter configuration may include that the thickness of the steel billet is greater than or equal to 3.5 mm, the number of steel billet blocks is greater than or equal to 3, and the rolling width difference between adjacent steel billets is less than or equal to 200 mm;

[0035] In some examples, the third preset rolling parameter configuration is the specific parameters of the rebound transition material preset to ensure that the steel can better transition and meet the subsequent processing requirements during the rolling process. The rebound transition material refers to the transitional steel billet that appears during the rolling process, which is transformed from a thicker steel billet to a thinner steel billet; since the shape and size of the steel billet may fluctuate greatly in the early stage of rolling, the rebound transition material, as the steel in the transition stage, ensures the stability of the steel billet size and promotes the smooth progress of the rolling process; in this step, a steel billet with a thickness greater than or equal to 3.5 mm is selected as the rebound transition material, so that such steel can enter the next stage of the finishing process more smoothly after the initial rolling.

[0036] Exemplarily, according to the third preset rolling parameter configuration, steel billets with a thickness greater than or equal to 3.5 mm, a number of blocks greater than or equal to 3, and a rolling width difference between adjacent steel billets less than or equal to 200 mm can be selected for rolling of rebound transition materials, thereby ensuring the uniformity of steel deformation during the transition stage and avoiding production problems caused by uneven thickness.

[0037] Through the implementation of step 103, the configuration of the billet thickness (≥3.5mm) and the number of pieces (≥3 pieces) of the rebound transition material can effectively alleviate the pressure fluctuation caused by the deformation or width difference of the transition material during the rolling process, and play a role in smooth transition; controlling the rolling width difference of adjacent billets (≤200mm) avoids the need for frequent roll changes, making the rolling process more continuous and stable.

[0038] Step 104, obtaining the first rebound enlarged unit main rolling material according to the fourth preset rolling parameter configuration, and rolling the first rebound enlarged unit main rolling material, wherein the fourth preset rolling parameter configuration may include that the billet type is automobile steel, the billet thickness is greater than or equal to 3 mm, the number of billet blocks is less than or equal to 40, and the difference between the billet rolling width and the minimum billet rolling width of the pickled steel main rolling material is less than or equal to 400 mm;

[0039] In some examples, the fourth preset rolling parameter configuration refers to a set of detailed rolling parameters set according to factors such as specific steel type, thickness, number of blocks and width difference, which are used to optimize the production process and ensure high quality of the final product. The first rebound expansion unit main rolling material is the steel that begins to enter the rebound expansion unit main rolling stage after a certain thickness change. In this step, the steel billet variety is automobile steel, the thickness is greater than or equal to 3 mm, and the number of blocks is less than or equal to 40. As the first rebound expansion unit main rolling material, it is selected to ensure that it can smoothly transition to the main rolling stage and meet the required specifications. Automobile steel refers to high-strength steel specially used for automobile manufacturing, with high tensile strength, excellent processing performance and corrosion resistance.

[0040] Exemplarily, according to the fourth preset rolling parameter configuration, a steel billet that meets the specifications of automobile steel is selected, with a thickness greater than or equal to 3 mm, a number of blocks not exceeding 40, and the difference between the rolling width of the steel billet and the minimum width of the pickled steel main rolling material is ensured to be less than or equal to 400 mm. Such a configuration can help avoid the need to frequently change rolls or adjust rolling parameters due to large differences in specifications, and reduce the frequency of roll changes and downtime. For example, when rolling pickled steel plates, if there is no suitable transition material, directly processing steel billets with large differences in specifications will increase the equipment adjustment time and roll change time. Through reasonable transition material arrangement, it can be ensured that steels of different specifications can be smoothly connected, reducing the downtime caused by adjustments during the production process; through the use of rebound transition materials, it can be avoided that the specification difference has an excessive impact on the roll, and the need for frequent roll replacement can be reduced, thereby improving the equipment's use efficiency and production efficiency.

[0041] Through the implementation of step 104, the control of the billet thickness (≥3mm) and the billet width difference (≤400mm) can ensure the matching of the main rolled material with the previous rolled material, reduce the number of roll changes caused by specification mismatch, and improve rolling efficiency; the control of the number of blocks (≤40) ensures the load stability of the production line, avoids production interruptions or excessive equipment load caused by excessive changes in steel types, thereby improving equipment utilization and reducing downtime.

[0042] In summary, the embodiments of the present application can make the rolling process more refined and reduce roll changing and downtime by setting different rolling parameter configurations for different types of steel (such as pickled steel start-rolling transition material, pickled steel main rolling material, rebound transition material, etc.); for example, the rolling setting of the start-rolling transition material is different from that of the subsequent main rolling material, so that the production line can be started smoothly at the initial stage of rolling, and the reasonable arrangement of the rebound transition material and the rebound expansion unit main rolling material reduces the frequency of steel billet roll changing and downtime, thereby improving the rolling efficiency and the stability of the production line; and by reasonably allocating parameters such as the number of steel billet blocks and thickness, it avoids waste of resources caused by improper handling during the rolling process; by setting specific requirements such as the thickness, number of blocks, width, etc. of the steel billet, it ensures that the rolling conditions of each steel are optimized and the quality of the steel after rolling is guaranteed; for example For example, when processing the main rolled material of pickled steel, surface defects caused by uneven thickness can be effectively avoided by precisely controlling the thickness; the thickness of the rebound transition material is greater than or equal to 3.5 mm, and the rolling width difference is limited, which can reduce surface defects during the rolling process and ensure the quality of the finished product; in addition, the rolling width difference of the main rolled material of the first rebound expansion unit is less than or equal to 400 mm, which further controls the uniformity and surface flatness of the steel and reduces quality fluctuations; by setting the restrictions on the "number of billet blocks" and "rolling width difference", frequent roll changes and shutdowns caused by unreasonable scheduling are avoided, especially in the scheduling of the main rolled material of the first rebound expansion unit, the control of the billet width difference can reduce the number of roll changes during the production process, thereby reducing production interruption time and improving equipment utilization. In summary, the pickled steel rolling method provided in the embodiment of the present application optimizes steel quality, improves rolling efficiency, reduces roll change and downtime by accurately setting the rolling parameters of different steels, thereby improving production line stability and resource utilization, and reducing production costs.

[0043] In some embodiments, it may also include: obtaining the second rebound expansion unit main rolling material according to the fifth preset rolling parameter configuration, and rolling the aforementioned second rebound expansion unit main rolling material, wherein the fifth preset rolling parameter configuration may include that the billet type is container steel, the billet thickness is greater than or equal to 3 mm, the difference between the billet rolling width and the minimum billet rolling width of the pickling steel main rolling material is less than or equal to 400 mm, and the sum of the number of billet blocks of the first rebound expansion unit main rolling material and the number of billet blocks of the second rebound expansion unit main rolling material is less than or equal to 70.

[0044] In some examples, the fifth preset rolling parameter configuration refers to a set of predetermined parameters set according to production requirements and steel specifications, which help optimize the rolling process and ensure product quality and production efficiency. Similar to the first rebound expansion unit main rolling material, the second rebound expansion unit main rolling material is a steel processing unit set up to avoid production interruptions and optimize the rolling process. Container steel refers to steel used to manufacture containers, which usually needs to have high strength, corrosion resistance, good weldability and impact resistance to withstand the complex environment and high-intensity physical pressure that may be encountered during transportation. The minimum billet rolling width of the pickled steel main rolling material refers to the minimum width of the billet used when rolling the pickled steel main rolling material.

[0045] Exemplarily, according to the fifth preset rolling parameter configuration, container steel is selected as the billet variety, ensuring that the thickness of the billet is greater than or equal to 3 mm, and the difference between the billet rolling width and the minimum billet width of the pickled steel main rolling material is less than or equal to 400 mm, ensuring that the size of the billet during the rolling process meets the requirements; through this configuration, the second rebound expansion unit main rolling material can be reasonably adjusted during the rolling process, and the total number of billet blocks of the first rebound expansion unit main rolling material and the second rebound expansion unit main rolling material is ensured not to exceed 70, thereby reducing waste and downtime in production, improving rolling efficiency and ensuring product quality and production stability.

[0046] Through the implementation of the above embodiments, a reasonable combination of different steel types (container steel) and rolling parameters is achieved, unreasonable combinations of the number of steel billets are avoided, the production process is optimized, and the waste of steel billets and downtime in the production process are reduced, thereby improving the overall efficiency of the production line.

[0047] In some embodiments, the aforementioned first preset rolling parameter configuration may also include: the number of steel billet blocks with a thickness of 2.5 mm is less than or equal to 3.

[0048] Exemplarily, during the rolling process, for a material with a billet thickness of 2.5 mm, the number cannot exceed 3.

[0049] Through the implementation of the above-mentioned embodiments, further refined control of the rolling transition material (control of the number of 2.5 mm thick steel billet blocks) helps to optimize the specifications of the rolling transition material, avoid excessive deformation of the steel billet, improve the stability of the rolling stage and product quality, and reduce potential defects in the subsequent rolling process.

[0050] In some embodiments, the main pickled steel rolled product is C material pickled steel rolled product or high-strength pickled steel rolled product.

[0051] Exemplarily, C material pickled steel is ordinary carbon steel (Carbon Steel) that has been pickled. It is usually used to manufacture some ordinary structural materials. It has lower strength and better processability. The pickling treatment is used to remove the oxide scale on the surface of the steel and improve the surface quality of the steel. For example, a common C material pickled steel may be used for body structural parts in the automotive industry, or supporting materials in the construction industry. The strength of these steels does not need to be particularly high, but the surface is required to be smooth and free of oxide layer for subsequent processing and use. High-strength pickled steel rolled products are high-strength steels that have been pickled. They have high yield strength and tensile strength. They are usually used to withstand large forces or in special environments. When this type of steel is rolled, in addition to surface treatment, the strength of the steel itself is relatively high, and it is suitable for application scenarios that require higher mechanical properties. For example, high-strength pickled steel is often used in automobile manufacturing for frames, bridges and other parts that need to withstand large loads, or for the production of some high-strength structural parts, such as the load-bearing parts of high-rise buildings or heavy machinery parts.

[0052] The implementation of the above-mentioned embodiments helps to ensure the high quality standards of the main rolled products, especially in industries such as automobiles that have high requirements for steel performance, and can provide steel types that better meet actual needs.

[0053] In some embodiments, the aforementioned step 102 may include: obtaining C material pickled steel rolled product according to a sixth preset rolling parameter configuration, and rolling the C material pickled steel rolled product, wherein the sixth preset rolling parameter configuration may include a steel billet thickness less than or equal to 2.5 mm and a number of steel billet blocks less than or equal to 30; obtaining high-strength pickled steel rolled product according to a seventh preset rolling parameter configuration, and rolling the high-strength pickled steel rolled product, wherein the seventh preset rolling parameter configuration may include a steel billet thickness less than or equal to 2.5 mm and a number of steel billet blocks less than or equal to 20.

[0054] In some examples, the sixth preset rolling parameter configuration refers to a specific set of rolling parameter settings applicable to the production rolling of C material pickled steel products; the configuration requires that the thickness of the steel billet does not exceed 2.5 mm and the number of steel billet blocks does not exceed 30; through these parameter configurations, the production efficiency and quality of C material pickled steel products can be ensured. The seventh preset rolling parameter configuration refers to a specific set of rolling parameter settings applicable to the production of high-strength pickled steel products; the configuration requires that the thickness of the steel billet does not exceed 2.5 mm and the number of steel billet blocks does not exceed 20; these parameter configurations are intended to ensure the strength and surface quality of high-strength pickled steel products.

[0055] Through the implementation of the above embodiments, the production efficiency and quality of different types of pickled steels (C material pickled steel and high-strength pickled steel) during the rolling process can be ensured; specifically, the thickness and number of steel billets are controlled so that various types of pickled steels can achieve the expected strength and surface quality to meet the needs of different applications.

[0056] In some embodiments, the aforementioned sixth preset rolling parameter configuration may also include: the number of steel billet blocks with a thickness less than or equal to 2 mm is less than or equal to 15, and the number of steel billet blocks with a thickness less than 2 mm is less than or equal to 6; the aforementioned seventh preset rolling parameter configuration may also include: the number of steel billet blocks with a thickness less than or equal to 2 mm is less than or equal to 12, and the number of steel billet blocks with a thickness less than 2 mm is less than or equal to 6.

[0057] Exemplarily, in the sixth preset rolling parameter configuration, by setting the steel billet thickness to be less than or equal to 2 mm and controlling the number of steel billet blocks with a thickness of less than 2 mm to within 6 pieces, the surface quality and dimensional consistency of the C material pickled steel can be effectively controlled, ensuring that the rolled steel meets the quality standards; in the seventh preset rolling parameter configuration, by setting the steel billet thickness to be less than or equal to 2 mm and the number of steel billet blocks with a thickness of less than 2 mm to not more than 6 pieces, it can be ensured that the high-strength pickled steel has higher tensile strength and durability during the rolling process.

[0058] Through the implementation of the above-mentioned embodiments, more detailed adjustments can be ensured to cope with the rolling requirements of steels of different thicknesses, the generation of surface defects of steels can be avoided, and the uniformity and surface quality of products can be improved.

[0059] In some embodiments, the aforementioned second preset rolling parameter configuration may also include: the width of the steel billet is greater than or equal to 1000 mm.

[0060] Exemplarily, the second preset rolling parameter configuration not only limits the thickness and number of the steel billet, but can also further specify the width condition of the steel billet, that is, the width of the steel billet should be greater than or equal to 1000 mm.

[0061] The implementation of the above embodiments helps to improve the production capacity of the main rolled material, especially when processing large-width steel billets, it can fully utilize the processing capacity of the production equipment, reduce frequent roll changes, downtime and adjustment time, and improve rolling efficiency and equipment utilization.

[0062] Based on the pickled steel rolling method provided in the embodiment of the present application, the rolling parameter configuration for different types of steel is improved, and the production efficiency is improved and the time for frequent adjustment and roll changing in the production process is effectively reduced through precise thickness, width and block number control. For example, by adjusting the rolling rhythm and number of blocks of high-strength pickled steel and ordinary pickled steel (Steel Plate for Hot-rolled Commercial, SPHC), it is possible to maximize the output and reduce roll changing and downtime while ensuring production stability. The improved scheme not only improves the overall efficiency of the production line, but also significantly improves the hourly output, and minimizes the production rhythm, ensuring higher production efficiency and stability. The following table shows the changes in production efficiency and output of high-strength pickled steel and ordinary pickled steel before and after the improvement of the pickled steel rolling method provided in the embodiment of the present application, further verifying the effect of the optimization scheme.
