Description

Technical Field

[0001] This application relates to the field of steel bar rolling technology, and discloses a method, apparatus, medium and electronic equipment for reducing steel bar cutting damage. Background Technology

[0002] The production process of straight steel bars on the long steel bar production line involves rolling continuously cast billets with a cross-sectional size of 150mm×150mm and a length of 12m into steel bars of different specifications and sizes through the rolling mill's built-in dies. According to the law of constant volume, the length of steel bars produced from the same continuously cast billet will vary greatly due to the large difference in cross-sectional area between different specifications of steel bars. The bar cooling bed length is 120m, but the length of the steel bars rolled through the rolling mill dies is no less than 360m. Therefore, the steel bars need to be cut into specific lengths using a multiple-length flying shear located after the rolling mill, and the length cannot exceed the 120m length of the cooling bed. The multiple-length cutting length can be set through the multiple-length flying shear control program. Next, the steel bars cut into sections by the multiple-length flying shear are collected and cooled on the cooling bed. Then, the sections of steel bars are cut into 12-meter fixed lengths by a 1300T cold shear at the cooling bed exit. Finally, they are packaged into bundles of sellable steel bars in the collection area. The length of multiple-length shearing is crucial. After the transformation of long steel bars to achieve direct rolling of continuously cast billets without heating, the length of multiple-length shearing still follows the control method of multiple-length shearing when heating in a heating furnace. After multiple-length shearing, the lengths of the segments are not uniform. After collection on the cooling bed, the segments of steel bars are cut into 12-meter lengths by a 1300T cold shear. Often, there are many steel bars with less than 12 meters of excess length, which can only be sent to scrap steel. This fails to give full play to the advantages of direct rolling of continuously cast billets without heating.

[0003] When continuously cast billets are heated in a heating furnace and then rolled, considering the furnace size, the billet length must not exceed 12 meters. Therefore, the lengths of each section must be modified to be different; otherwise, the billet length will exceed the furnace size, and the billet cannot be fed into the furnace. In this case, the factors influencing the determination of the multiple lengths include: 1. The influence of production specifications: different specifications of products have different cross-sectional areas, resulting in different lengths of steel bars rolled from the continuously cast billets; 2. The multiple lengths are transferred to the cooling bed in sections, requiring that the multiple length not exceed the cooling bed length, and the number of multiple lengths should be minimized; 3. The influence of the fixed length: different fixed lengths result in different multiple lengths. Due to the factors mentioned above, the length of the segmented multiple-length steel bars will vary. Compared to the long multiple-length steel bars, the longer the multiple-length steel bar, the smaller the proportion of the head and tail material in the total weight of the segmented multiple-length steel bar. This results in more steel bars per continuous casting billet and better efficiency. Therefore, the yield of short multiple-length steel bars is lower than that of long multiple-length steel bars.

[0004] Based on this, a method to reduce steel bar cutting loss is proposed. After the implementation of the direct rolling technology without heating for bar stock, by controlling the length of multiple lengths and determining the appropriate length of the continuous casting billet, the straight steel bars can be cut to full length, eliminating the generation of short lengths, and achieving the goal of significantly reducing cutting loss and improving the efficiency of bar stock production lines.

[0029] The implementation details of the technical solutions in the embodiments of this application are described in detail below:

[0030] Figure 1 A flowchart of a method for reducing steel bar cutting damage according to an embodiment of this application is shown.

[0031] like Figure 1 As shown, the method for reducing steel bar cutting damage includes at least steps 110 to 160.

[0032] The following will be about Figure 1 Steps 110 to 160 are described in detail below:

[0033] In step 110, a first length of the steel billet and a second length of the reinforcing bar are obtained, the reinforcing bar being rolled from the steel billet by a rolling mill.

[0034] In this application, the steel billet is typically a continuously cast billet with a cross-sectional size of 150mm×150mm and a length of 12m. The continuously cast billet can be rolled into steel bars of different specifications and sizes through the die provided by the rolling mill.

[0035] In this application, according to the law of constant volume, for the same continuously cast billet, due to the large difference in the cross-sectional area of ​​different specifications of steel bars, the length of the steel bars produced by the same continuously cast billet will also vary greatly, making it difficult to obtain the required length of steel bars. The length of steel bars rolled by the rolling mill is not less than 360 meters. The length of steel bars can be obtained through the operation backend connected to the rolling mill, or through measuring equipment.

[0036] Continue to refer to Figure 1 In step 120, based on the first length and the second length, a conversion factor is determined for the steel billet and the reinforcing bar, the conversion factor being used to characterize the proportional relationship between the length of the steel billet and the length of the reinforcing bar.

[0037] Continue to refer to Figure 1 In step 130, a fixed length is obtained, which is the length of the target finished steel bar.

[0038] In this application, the target finished steel bars are cut into fixed lengths by a 1300T cold shear at the outlet of the cooling bed, and finally packaged into bundles of sellable steel bars in the collection area.

[0039] In this application, the standard length is typically 12 meters, but it can also be other specific lengths, which can be adjusted for production as needed.

[0040] Continue to refer to Figure 1 In step 140, based on the fixed length, a multiple-length shearing length is determined, which is the specific length required for the multiple-length flying shear located after the rolling mill to shear the target steel bar.

[0041] In this application, the multiple-length shearing length can be set by the multiple-length flying shear control program. The multiple-length flying shear cuts the steel bars into a specific length, which is the multiple-length shearing length. The cut steel bars are collected and cooled on a cooling bed.

[0042] Continue to refer to Figure 1 In step 150, the length of the target reinforcing bar is determined based on the multiple-length shearing length.

[0043] Continue to refer to Figure 1 In step 160, the length of the target steel billet is determined based on the length of the target steel bar and the conversion factor.

[0044] In one embodiment of this application, determining the conversion factor of the steel billet and the reinforcing bar based on the first length and the second length includes: calculating the ratio of the first length and the second length, and using the ratio as the conversion factor of the steel billet and the reinforcing bar.

[0045] In this application, the quotient of the length of the steel billet divided by the length of the reinforcing bar rolled from the steel billet is calculated, and the quotient is used as the conversion factor for the steel billet and the reinforcing bar.

[0046] In this application, for example, if the length of the steel billet is 12 meters and the length of the reinforcing bar is 430 meters, then the conversion factor is 0.028.

[0047] In one embodiment of this application, determining the multiple-length shearing length based on the fixed length includes: obtaining a third length of a cooling bed, the cooling bed being used to cool the reinforcing bars sheared by the multiple-length flying shear; obtaining an initial multiple-length shearing length; calculating the sum of the initial multiple-length shearing length and the error length to obtain an intermediate multiple-length shearing length; determining whether the intermediate multiple-length shearing length is greater than the third length; if the intermediate multiple-length shearing length is less than or equal to the third length, then using the intermediate multiple-length shearing length as the target multiple-length shearing length.

[0048] In this application, the length of the cooling bed is typically 120 meters. The error length includes at least the shrinkage length and the head and tail shearing length. The shrinkage length is set because the temperature of the steel bars on the cooling bed is generally around 900℃, while the temperature of the steel bars in the 1300T cold shear at the cooling bed outlet is generally around 200℃. This length takes into account the thermal expansion and contraction of the steel bars. The head and tail shearing length is set when the 1300T cold shear cuts the steel bars to length, requiring the cutting of the head and tail of each segment of multiple length steel bars to remove problems such as bending at the head and tail and burrs. The head and tail shearing length is typically 15-20cm. The longer the multiple length, the smaller the proportion of the head and tail material of the segmented multiple length to the total weight of the multiple length, and the more steel bars are obtained from a single continuous casting billet.

[0049] In this application, the sum of the initial multiple-length shearing length and the error length is calculated to obtain the intermediate multiple-length shearing length. Since the steel bars sheared by the multiple-length flying shear cannot exceed the length of the cooling bed, it is necessary to determine whether the intermediate multiple-length shearing length exceeds the length of the cooling bed. If it is less than or equal to the length of the cooling bed, the intermediate multiple-length shearing length is taken as the target multiple-length shearing length. The target multiple-length shearing length can be set as the multiple-length flying shear length through the multiple-length flying shear control program.

[0050] In one embodiment of this application, obtaining the initial multiple shear length includes: obtaining the greatest common multiple of the fixed length that is less than or equal to the third length, and using the greatest common multiple as the initial multiple shear length.

[0051] In this application, the greatest common multiple of the fixed length is obtained, but it cannot be greater than the length of the cooling bed. That is, the greatest common multiple of the fixed length is obtained within the range of less than or equal to the length of the cooling bed, and the greatest common multiple is used as the initial multiple length.

[0052] In one embodiment of this application, the method further includes: if the intermediate multiple-length cutting length is greater than the third length, determining the difference between the initial multiple-length cutting length and the fixed length, and using the difference as the new initial multiple-length cutting length; calculating the sum of the new initial multiple-length cutting length and the error length to obtain the target multiple-length cutting length.

[0053] In this application, if the intermediate multiple-length shearing length is greater than the cooling bed length, it means that the intermediate multiple-length flying shear length cannot be used as the target multiple-length shearing length because full-length shearing is required. Therefore, the difference between the initial multiple-length flying shear length and the fixed-length length is calculated, and the difference is used as the new initial multiple-length shearing length. The sum of the new initial multiple-length shearing length and the error length is calculated to obtain the target multiple-length shearing length. The target multiple-length shearing length can be set as the multiple-length flying shear length through the multiple-length flying shear control program.

[0054] In one embodiment of this application, determining the length of the target reinforcing bar based on the multiple shear length includes: determining a multiple of the multiple shear length based on the multiple shear length; calculating the product of the multiple shear length and the multiple, and using the product as the length of the target reinforcing bar.

[0055] In this application, the multiple of the multiple shearing length can be determined according to actual production needs, and the product of the multiple shearing length and the multiple can be calculated, and the product can be used as the length of the target steel bar.

[0056] In one embodiment of this application, determining the length of the target steel billet based on the length of the target reinforcing bar and the conversion factor includes: calculating the product of the length of the target reinforcing bar and the conversion factor, and using the product as the length of the target steel billet.

[0057] In this application, for example, if the length of the target reinforcing bar is 555 meters and the conversion factor is 0.028, then the length of the target steel billet is 555 × 0.028 = 15.5 meters.

[0058] To enable those skilled in the art to more easily understand this application, a specific embodiment will be used to illustrate this application below.

[0059] After implementing the technology transformation of direct rolling without heating for bar stock, the continuous casting billet is directly rolled through the rolling mill's own die without entering the heating furnace. The continuous casting billet can be adjusted to be greater than 12 meters. With a cooling bed length of 120 meters, straight steel bars are produced. The operation plan is explained.

[0060] When producing 12-meter standard length rebar, a 120-meter cooling bed could theoretically allow for multiple lengths to be set to 120 meters, with 10 standard lengths cut from each multiple length. However, considering the thermal expansion and contraction of the rebar at high temperatures and the cutting of rebar at the beginning and end of segmented multiple lengths, the multiple length needs to be increased by an additional 3 meters. Therefore, the multiple length can only be set to 108 meters, increasing the cold shrinkage by 3 meters. The final multiple length is set to 111 meters, allowing for the cutting of 9 standard lengths that can successfully reach the cooling bed. Through this operation, with the same cutting loss, the number of qualified standard lengths can be increased by 9.

[0061] Based on the existing correspondence between billet length and existing rolled steel (reinforcing bar) length, the continuous casting billet length corresponding to the new multiple-length control method can be calculated, providing a basis for steel pulling in the continuous casting process. The specific calculation method is as follows:

[0062] L2 = B2 × L1 / B1,

[0063] Where L1 and L2 represent the original billet length and the required billet length, respectively, and B1 and B2 represent the original rolled material length and the current rolled material length, respectively.

[0064] The specific changes in billet length and rolled product length before and after production for each specification of rebar are shown in Table 1 below:

[0065]

[0066]

[0067] Table 1

[0068] Therefore, given a specified rebar specification, the required billet length can be determined based on the actual needs of the target rebar length. This can guide the billet production personnel to cast the required billets, and after rolling, the appropriate rebar length can be obtained. This enables the full-length cutting of straight rebars, eliminating the production of short lengths, and significantly reducing cutting losses and improving the efficiency of the bar production line.

[0069] The one or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0070] This application implements a direct rolling technology without heating when rolling long steel bars into reinforcing bars. The continuously cast billets are rolled directly without entering the heating furnace, which avoids oxidation and burning problems. The length of the continuously cast billets can also be adjusted to be greater than 12 meters.

[0071] The technical solution proposed in this application achieves full-length cutting of straight steel bars by controlling the length of the multiple-length sections, thus avoiding the situation where the lengths of the multiple-length sections are inconsistent, resulting in a lot of excess steel bars that are less than 12 meters long. In this case, the excess steel bars can only be treated as scrap steel, which reduces production efficiency.

[0072] The technical solution proposed in this application can eliminate the occurrence of short lengths, thereby significantly reducing the amount of steel bar cutting loss and improving the production efficiency of long steel bar production lines.
