[0017] To sum up, the present application sets different rolling parameter configurations for different types of steel materials (such as pickling steel opening rolling transition material, pickling steel main rolling material, reverse jump transition material, etc.), so that the rolling process can be more finely managed, and the roll changing and downtime can be reduced. For example, the rolling setting of the opening rolling transition material is different from that of the subsequent main rolling material, which can smoothly start the production line at the initial stage of rolling. The reasonable arrangement of the reverse jump transition material and the reverse jump expansion unit main rolling material reduces the frequency of changing the billet and the downtime, thereby improving the rolling efficiency and the stability of the production line. By reasonably allocating the parameters such as the number of billets and the thickness, the waste of resources caused by improper handling during the rolling process can be avoided. By setting specific requirements for the thickness, the number of billets, the width, etc., the rolling conditions of each type of steel material can be optimized, and the quality of the rolled steel material can be ensured. For example, when processing the pickling steel main rolling material, the thickness can be accurately controlled to effectively avoid surface defects caused by uneven thickness. The thickness of the reverse jump transition material is greater than or equal to 3.5 mm, and the rolling width difference is limited, which can reduce surface defects during rolling and ensure the quality of the finished product. In addition, the rolling width difference of the first reverse jump expansion unit main rolling material is less than or equal to 400 mm, which further controls the uniformity and surface flatness of the steel material and reduces the quality fluctuation. By setting the limits of the "number of billets" and the "rolling width difference", the frequent roll changing and downtime caused by unreasonable arrangement can be avoided, especially in the arrangement of the first reverse jump expansion unit main rolling material. The control of the billet width difference can reduce the number of roll changes during production, thereby reducing the production downtime and improving the utilization rate of the equipment. To sum up, the pickling steel rolling method provided by the present application can optimize the quality of the steel material, improve the rolling efficiency, reduce the roll changing and downtime, and thereby improve the stability of the production line and the resource utilization rate, and reduce the production cost.

[0024] The technical solutions in the present application will be described in detail below in conjunction with the drawings in the embodiments. It should be noted that the described embodiments are only a part of the present application, not all embodiments. In the following description, "some embodiments" mentioned is only a subset of all possible embodiments, which can be the same or different subset, and different embodiments can be combined with each other without conflict.

[0025] Figure 1is a flowchart of a rolling method of a pickled steel provided by an embodiment of the present application. By way of example, see Figure 1 The rolling method of the pickled steel provided by an embodiment of the present application can include the following steps 101 to 104:

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

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

[0028] By way of example, by selecting billets that meet the first preset rolling parameter configuration, such as 12 billets with a thickness greater than or equal to 2.5 mm, the rolling of the pickled steel open rolling transition material is carried out, ensuring the smooth start of the rolling equipment and making sufficient preparations for the subsequent rolling stage; through this configuration, the start of the production line is successfully achieved under the condition that the rolling process does not occur sharply, thereby improving the stability and efficiency of the subsequent main rolling material production.

[0029] Through the implementation of step 101, excessive deformation and waste at the initial stage of rolling can be avoided, and early load fluctuations can be reduced, ensuring the smooth start of the rolling process.

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

[0031] In some examples, the second preset rolling parameter configuration refers to the rolling parameters preset for the specific needs of the pickled steel main rolling material in the production process of the pickled steel, in order to ensure the smooth progress of the subsequent production stage. The pickled steel main rolling material refers to the steel that enters the formal production stage after preliminary processing in the production process of the pickled steel, and these steels are the basis for the final product. After main rolling, they will be converted into thinner steel with certain strength and surface quality.

[0032] For example, according to the second preset rolling parameter configuration, the steel billets with a thickness less than or equal to 2.5 mm and a block number less than or equal to 30 are selected to perform the rolling of the pickling steel main rolled material. Through this configuration, the production of the main rolled material can ensure the formation of high-quality pickling steel under the condition of accurate control of the thickness and block number of the steel material, thereby improving the efficiency of the production line and the qualified rate of the steel material.

[0033] Through the implementation of step 102, the accurate control of the thickness (≤2.5 mm) and block number (≤30) of the pickling steel main rolled material can ensure the consistency of the specifications of the steel material during the rolling process, thereby effectively avoiding the problem of uneven thickness during the rolling process.

[0034] In step 103, the skip transition material is obtained according to the third preset rolling parameter configuration, and the foregoing skip transition material is rolled, wherein the third preset rolling parameter configuration can include a steel billet thickness greater than or equal to 3.5 mm, a steel billet block number greater than or equal to 3, and a rolling width difference between adjacent steel billets less than or equal to 200 mm.

[0035] In some examples, the third preset rolling parameter configuration is a specific parameter of the skip transition material that is preset to ensure that the steel material can better transition during the rolling process and meet the subsequent processing requirements. The skip transition material refers to the transition steel billet that appears during the rolling process, which is the transition from a steel billet with a larger thickness to a steel billet with a smaller thickness. Since the shape and size of the steel billet may fluctuate greatly at the beginning of the rolling, the skip transition material as the steel material in the transition stage ensures the stability of the size of the steel billet and promotes the smooth progress of the rolling process. In this step, the steel billet with a thickness greater than or equal to 3.5 mm is selected as the skip transition material, which can more smoothly enter the next stage of the finish rolling process after passing through the initial rolling.

[0036] For example, according to the third preset rolling parameter configuration, the steel billet with a thickness greater than or equal to 3.5 mm, a block number 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 to perform the rolling of the skip transition material, thereby ensuring the uniformity of the deformation of the steel material in the transition stage and avoiding production problems caused by uneven thickness.

[0037] Through the implementation of step 103, the configuration of the thickness (≥3.5 mm) and block number (≥3 blocks) of the skip transition material can effectively alleviate the pressure fluctuation caused by the deformation or width difference of the transition material during the rolling process, thereby playing a role in smooth transition. Controlling the rolling width difference (≤200 mm) between adjacent steel billets avoids the frequent need for roll replacement, thereby making the rolling process more continuous and stable.

[0038] In step 104, the first skip-expanding unit main rolled material is obtained according to the fourth preset rolling parameter configuration, and the first skip-expanding unit main rolled material is rolled, wherein the fourth preset rolling parameter configuration can include that the billet variety is automobile steel, the billet thickness is greater than or equal to 3 mm, the billet block number 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 rolled 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 specific steel material categories, thicknesses, block numbers, and width differences, etc., for optimizing the production process and ensuring high-quality final products. The first skip-expanding unit main rolled material is a steel material that has undergone a certain thickness change and has begun to enter the skip-expanding unit main rolling stage. In this step, the billet variety is selected as automobile steel, the thickness is greater than or equal to 3 mm, and the block number is less than or equal to 40, to ensure that it can smoothly transition to the main rolled material stage and achieve the required specifications. Automobile steel refers to high-strength steel material specifically used for automobile manufacturing, which has high tensile strength, excellent processing performance, and corrosion resistance.

[0040] For example, according to the fourth preset rolling parameter configuration, billets that meet the specifications of automobile steel are selected, with a thickness greater than or equal to 3 mm, a block number not exceeding 40, and a billet rolling width difference from the minimum billet width of the pickled steel main rolled material less than or equal to 400 mm. This configuration can help avoid the need for frequent roll changes or adjustments of rolling parameters due to large specification differences, reducing roll change frequency and downtime. For example, when rolling pickled steel plates, if there is no suitable transition material, directly processing steel billets with large specification differences will increase equipment adjustment time and roll change time. Through reasonable transition material arrangement, different specifications of steel can be smoothly connected, reducing downtime caused by adjustments in the production process; through the use of skip-expanding transition materials, the impact of specification differences on the roll can be avoided, reducing the need for frequent roll changes, thereby improving the efficiency of the equipment and the production efficiency.

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

[0042] In summary, the rolling method for pickling steel provided in the embodiments of the present application can improve the stability of the production line and the utilization rate of resources, reduce the production cost by accurately setting the rolling parameters of different steel materials, optimizing the quality of steel materials, improving the rolling efficiency, and reducing the roll changing and downtime.

[0043] In some embodiments, the method can further include: obtaining a second reverse jump expansion unit main rolling material according to a fifth preset rolling parameter configuration, and rolling the second reverse jump expansion unit main rolling material, wherein the fifth preset rolling parameter configuration can include that the steel billet variety is container steel, the steel billet thickness is greater than or equal to 3 mm, the difference between the steel billet rolling width of the second reverse jump expansion unit main rolling material and the minimum steel billet rolling width of the pickling steel main rolling material is less than or equal to 400 mm, and the sum of the steel billet block number of the first reverse jump expansion unit main rolling material and the steel billet block number of the second reverse jump 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 pre-specified parameters set according to production requirements and steel specifications, which help to optimize the rolling process and ensure the quality and production efficiency of the product. Similar to the first skip-up unit main rolling material, the second skip-up unit main rolling material is a steel processing unit set to avoid production interruption and optimize the rolling process. Container steel refers to steel used to manufacture containers, which generally needs to have high strength, corrosion resistance, good weldability, and impact resistance to withstand complex environments and high-strength physical pressure that may be encountered during transportation. The minimum billet rolling width of the pickling steel main rolling material refers to the minimum width of the billet used when rolling the pickling steel main rolling material.

[0045] For example, 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 rolling width of the billet and the minimum billet width of the pickling steel main rolling material is less than or equal to 400 mm, ensuring that the size of the billet meets the requirements during rolling. Through this configuration, the second skip-up unit main rolling material can be reasonably adjusted during rolling, and the total number of billet blocks of the first skip-up unit main rolling material and the second skip-up unit main rolling material is ensured to be no more than 70, thereby reducing waste and downtime during production, improving rolling efficiency, and ensuring product quality and production stability.

[0046] Through the implementation of the above examples, a reasonable combination of different steel types (container steel) and rolling parameters is achieved, avoiding unreasonable billet block combinations, optimizing the production process, reducing billet waste and downtime during production, and thereby improving the overall efficiency of the production line.

[0047] In some examples, the first preset rolling parameter configuration can further include that the number of billet blocks with a thickness of 2.5 mm is less than or equal to 3.

[0048] For example, during rolling, the number of materials with a billet thickness of 2.5 mm cannot exceed 3.

[0049] Through the implementation of the above examples, further refined control of the roughing transition material (control of the number of 2.5 mm thick billet blocks) helps to optimize the specifications of the roughing transition material, avoids excessive deformation of the billet, improves the stability and product quality of the roughing stage, and reduces potential defects in the subsequent rolling process.

[0050] In some examples, the pickling steel main rolling material is C-grade pickling steel rolling material or high-strength pickling steel rolling material.

[0051] For example, 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 and are usually used to withstand large forces or be used in special environments. When this type of steel is rolled, in addition to surface treatment, the strength of the steel itself is 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 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 the sixth preset rolling parameter configuration, and rolling the C material pickled steel rolled product, wherein the sixth preset rolling parameter configuration may include the steel billet thickness being less than or equal to 2.5 mm and the number of steel billet blocks being less than or equal to 30; obtaining high-strength pickled steel rolled product according to the seventh preset rolling parameter configuration, and rolling the high-strength pickled steel rolled product, wherein the seventh preset rolling parameter configuration may include the steel billet thickness being less than or equal to 2.5 mm and the number of steel billet blocks being 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 of C-grade pickled steel products; this configuration requires that the billet thickness does not exceed 2.5 mm and the number of billet blocks does not exceed 30; these parameter configurations ensure the production efficiency and quality of C-grade pickled steel products. 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; this configuration requires that the billet thickness does not exceed 2.5 mm and the number of billet blocks does not exceed 20; these parameter configurations are intended to ensure the strength and surface quality of the high-strength pickled steel products.

[0055] Through the implementation of the above embodiments, the production efficiency and quality of different types of pickled steel (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 steel 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 can further include: the number of billets with a thickness less than or equal to 2 mm is less than or equal to 15, and the number of billets with a thickness less than 2 mm is less than or equal to 6; the aforementioned seventh preset rolling parameter configuration can further include: the number of billets with a thickness less than or equal to 2 mm is less than or equal to 12, and the number of billets with a thickness less than 2 mm is less than or equal to 6.

[0057] For example, in the sixth preset rolling parameter configuration, by setting the thickness of the billet to be less than or equal to 2 mm, and the number of billets with a thickness less than 2 mm to be controlled within 6, the surface quality and size consistency of the C material pickling steel can be effectively controlled, and it is ensured that the rolled steel meets the quality standard; in the seventh preset rolling parameter configuration, by setting the thickness of the billet to be less than or equal to 2 mm, and the number of billets with a thickness less than 2 mm to be no more than 6, it can be ensured that the high-strength pickling steel has high tensile strength and durability during rolling.

[0058] Through the implementation of the above embodiments, more detailed adjustments can be ensured to meet the rolling needs of steel materials of different thicknesses, avoid the generation of surface defects of the steel materials, and improve the uniformity and surface quality of the products.

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

[0060] For example, the second preset rolling parameter configuration not only limits the thickness and the number of billets, but also further specifies the width condition of the billet, i.e., the width of the billet should be greater than or equal to 1000 mm.

[0061] Through the implementation of the above embodiments, it is helpful to improve the production capacity of the main rolling material, especially when processing large-width billets, the processing capacity of the production equipment can be fully utilized, the frequency of roll replacement, downtime and adjustment time is reduced, and the rolling efficiency and equipment utilization rate are improved.

[0062] Based on the rolling method of pickled steel provided in the embodiments 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 replacement in the production process is effectively reduced through accurate thickness, width and block number control. For example, by adjusting the rolling rhythm and block number of high-strength pickled steel and ordinary pickled steel (Steel Plate for Hot-rolled Commercial, SPHC), the production stability can be ensured while maximizing the yield and reducing the roll replacement and downtime. The improved scheme not only improves the overall efficiency of the production line, but also significantly improves the hourly output, and maximally shortens the production rhythm, ensuring higher production efficiency and stability. The following table shows the changes in production efficiency and yield of high-strength pickled steel and ordinary pickled steel before and after the rolling method of pickled steel provided in the embodiments of the present application is improved, further verifying the effect of the optimization scheme.
