Description

Technical Field

[0001] This application relates to the field of automatic control technology for continuous annealing production lines, and in particular to a cutting edge control method, device, medium, and equipment. Background Technology

[0002] The continuous rolling production line needs to roll strip steel of different specifications. The amount of trimming is different for different specifications of strip steel. Therefore, it is necessary to adjust the trimming width of the trimming shear. When it is necessary to adjust the trimming width of the trimming shear on the continuous rolling production line, the feed rate needs to be adjusted after stopping the cutting shear area (hereinafter referred to as blade adjustment).

[0003] Furthermore, to prevent the shearing blade from impacting the strip steel, a crescent shape needs to be pre-cut at the weld seam using crescent shears, and the blade is adjusted only after the crescent shape is positioned at the shearing blade head. This method has the following two disadvantages:

[0004] First, the production line needs to be shut down, which takes a long time and is not conducive to speeding up the continuous production line. Second, adjusting the blade at the crescent shape will cause the cut edges to break, potentially resulting in fraying.

[0005] In the dark, existing technology severely affects the production rhythm of continuous retraction production lines when adjusting the feed rate of the cutting shear, and production efficiency cannot be guaranteed. Summary of the Invention

[0021] If it is determined that the crescent shears did not perform a shearing operation at the weld seam between the current coil and the previous coil, then the side shape of the weld seam is determined to be non-crescent-shaped.

[0022] In the above scheme, determining whether the current strip steel meets the preset online adjustment strategy for edge trimming based on the weld side shape, the current strip steel trimming amount, and the actual thickness of the current strip steel includes:

[0024] In the above scheme, the determination of the online adjustment strategy for the cutting edge is triggered, including:

[0025] Obtain the weld position between the current coil and the previous coil;

[0026] If the actual width of the current coiled strip is less than the actual width of the previous coiled strip, and the weld position has not yet reached the edge shear position, and the distance between the weld and the edge shear reaches a preset distance, it is determined that the online adjustment strategy of the edge shear is triggered.

[0046] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0047] This invention provides a method for controlling edge trimming, such as... Figure 1 As shown, the method includes the following steps:

[0048] S110, determine the trimming amount of the current coiled strip based on the actual width of the current coiled strip and the actual width of the previous coiled strip;

[0049] When a steel coil enters the continuous annealing production line, its specifications, including model, thickness, and width, are acquired in real time. Therefore, the actual width and thickness of the current coil, as well as the actual width and thickness of the previous coil, can be obtained from this specifications.

[0050] In a continuous rolling mill, steel coils of different specifications can be rolled continuously. Different specifications of steel coils require different cutting edge widths, and therefore the required feed rate of the cutting shears also varies. Therefore, for any given coil of steel, the cutting edge amount must be determined based on the actual width of the current coil and the actual width of the previous coil.

[0051] In one embodiment, determining the trimming amount of the current coil based on the actual width of the current coil and the actual width of the previous coil includes:

[0052] If it is determined that the actual width of the current coiled strip is greater than or equal to the actual width of the previous coiled strip, the first cutting edge width of the current coiled strip is obtained.

[0053] The difference between the actual width of the current coiled strip and the first trimmed edge width is used as the trimmed edge amount of the current coiled strip.

[0054] In another embodiment, determining the trimming amount of the current coil based on the actual width of the current coil and the actual width of the previous coil includes:

[0055] If it is determined that the actual width of the current coil is less than the actual width of the previous coil, the second tangential width of the current coil is obtained.

[0056] The difference between the actual width of the previous coil and the second trimmed edge width is used as the trimmed edge amount of the current coil.

[0057] Specifically, refer to Figure 2Along the strip running direction, mark 21 represents the current coil of strip, mark 22 represents the previous coil of strip, mark 23 represents the weld between the current and previous coils of strip, and mark 24 represents the edge trimming shear. The actual width of the current coil of strip is greater than the actual width of the previous coil of strip. Therefore, the edge trimming amount of the current coil of strip is the difference between the actual width of the current coil of strip and the edge trimming width (the required width).

[0058] refer to Figure 3 Along the strip running direction, mark 31 represents the current coil of strip, mark 32 represents the previous coil of strip, mark 33 represents the weld between the current and previous coils of strip, and mark 34 represents the edge trimming shear. The actual width of the current coil of strip is less than the actual width of the previous coil of strip. Therefore, the edge trimming amount of the current coil of strip is the difference between the actual width of the previous coil of strip and the edge trimming width of the current coil of strip (the required width).

[0059] S111, Obtain the weld side shape of the current strip and the previous strip;

[0060] In traditional edge-cutting shear adjustment methods, to prevent the edge-cutting shear from impacting the strip steel, a crescent shape needs to be cut at the weld seam in advance using crescent shears (cutting an arc at both ends of the weld seam). When using the edge-cutting shear control method provided in this embodiment, it is not necessary to cut a crescent shape at the weld seam in advance. If a crescent shape is cut at the weld seam in advance, and the edge-cutting shear is adjusted using the method provided in this embodiment, the cut strip steel edge wire will break. Therefore, it is necessary to obtain the weld seam side shape of the current coil strip steel and the previous coil strip steel, and determine whether the online adjustment strategy of the edge-cutting shear is met based on the weld seam side shape.

[0061] In one embodiment, obtaining the weld side shape of the current coil and the previous coil includes:

[0062] Track the execution data of the crescent-shaped shears;

[0063] If it is determined that the crescent shears performed a shearing operation at the weld seam between the current coil and the previous coil, then the side shape of the weld seam is determined to be crescent-shaped.

[0064] If it is determined that the crescent shears did not perform a shearing operation at the weld seam between the current coil and the previous coil, then the weld side shape is determined to be non-crescent shape.

[0065] Specifically, the crescent-shaped shear is installed at the production line entrance, and the edge-cutting shear is installed at the production line exit. The execution data of the crescent-shaped shear can be tracked in real time to determine whether the crescent-shaped shear has performed a cutting operation at the weld seam of the current coil and the previous coil of strip. If a cutting operation is performed, it means that the side shape of the weld seam of the current coil and the previous coil of strip is crescent-shaped; if a cutting operation is not performed, it means that the side shape of the weld seam of the current coil and the previous coil of strip is not crescent-shaped.

[0066] S112, Based on the weld side shape, the current strip steel trimming amount, and the actual thickness of the current strip steel, determine whether the current strip steel meets the preset trimming shear online adjustment strategy;

[0067] In one implementation, determining whether the current strip meets the preset online trimming adjustment strategy based on the weld side shape, the current trimming amount of the current strip, and the actual thickness of the current strip includes:

[0068] If the weld side shape is determined to be non-crescent-shaped, the current strip thickness is between 0.45 and 0.9 mm, and the current strip trimming amount is less than or equal to the maximum feed rate of the trimming shear, then the current strip meets the online adjustment strategy for the trimming shear. The maximum feed rate of the trimming shear can be determined based on actual conditions; in this embodiment, the maximum feed rate is 80 mm.

[0069] Specifically, the thickness of the strip steel produced by the continuous strip production line is generally 0.45mm to 2.5mm. When producing thicker materials, the online adjustment strategy of the edge trimmer cannot be used, otherwise the blade of the edge trimmer will be damaged.

[0070] The difference in the cutting edge width between the current coil and the previous coil should not be too large, otherwise it will cause the cutting edge shear box to collide with the strip. Therefore, it is necessary to determine whether the current coil meets the preset online adjustment strategy of the cutting edge shear based on the shape of the weld side, the cutting edge amount of the current coil, and the actual thickness of the current coil.

[0071] S113, if satisfied, then when the online adjustment strategy of the cutting edge shear is triggered, the feed rate of the cutting edge shear is adjusted online.

[0072] If it is determined that the current strip steel meets the online adjustment strategy of the edge trimmer, it is further determined whether the online adjustment strategy of the edge trimmer has been triggered. If it is determined that the online adjustment strategy of the edge trimmer has been triggered, the feed rate of the edge trimmer is adjusted online.

[0073] In one implementation, determining that the online adjustment strategy for edge trimming is triggered includes:

[0074] Get the weld position between the current coil and the previous coil;

[0075] If the actual width of the current coiled strip is less than the actual width of the previous coiled strip, and the weld position has not yet reached the edge shear position, and the distance between the weld and the edge shear reaches the preset distance, the online adjustment strategy of the edge shear is triggered.

[0076] In another implementation, determining that the online adjustment strategy for edge trimming is triggered includes:

[0077] Get the weld position between the current coil and the previous coil;

[0078] If the actual width of the current coiled strip is greater than the actual width of the previous coiled strip, and the weld position has passed the edge shear position and the distance between the weld and the edge shear reaches the preset distance, the online adjustment strategy of the edge shear is triggered.

[0079] Specifically, the edge-trimming shear is located at the exit of the continuous annealing production line. Generally, the online adjustment strategy for the edge-trimming shear only begins when the wider strip steel reaches it. Therefore, you can refer to... Figure 2 If the actual width of the current coiled strip is greater than the actual width of the previous coiled strip, the weld position will need to pass the edge shear position before the online adjustment strategy of the edge shear will be triggered.

[0080] refer to Figure 3 If the actual width of the current coiled strip is less than the actual width of the previous coiled strip, the weld position needs to trigger the online adjustment strategy of the cutting edge shear before reaching the cutting edge shear position.

[0081] in, Figure 2 and Figure 3 The distance between the weld and the cutting shear is only an indication. The preset distance between the weld and the cutting shear can be in the millimeter range, such as 0.1 to 0.5 mm, or it can be determined based on the actual situation. There is no restriction here.

[0082] When the online adjustment strategy of the cutting shear is triggered, the feed rate of the cutting shear can be adjusted online based on the cutting edge width of the current coil. The cutting edge width of the strip is preset and can be obtained directly from the specification information.

[0083] In addition, if it is determined that the weld side shape is not crescent-shaped, the thickness of the current coiled strip is not between 0.45 and 0.9 mm, or the cutting amount of the current coiled strip is greater than the maximum feed amount of the cutting shear, it is determined that the online adjustment strategy of the cutting shear has not been triggered. If the weld reaches the cutting shear, a stop operation will be performed and the adjustment will continue in the traditional manner.

[0084] The edge-cutting shear control method provided in this embodiment allows for direct adjustment of the edge-cutting shear feed rate without stopping the machine if the preset online adjustment strategy for each current coiled strip is met, thus avoiding affecting the production rhythm and improving production efficiency.

[0085] Furthermore, it can effectively prevent edge wire burrs caused by adjusting the tool at the crescent-shaped part of the weld, reduce abnormal operations, and improve the stability of the production process.

[0086] Based on the same inventive concept as in the foregoing embodiments, this embodiment also provides a cutting edge control device, such as... Figure 4 As shown, the device includes:

[0087] The determining unit 41 is used to determine the cutting edge amount of the current coiled strip based on the actual width of the current coiled strip and the actual width of the previous coiled strip.

[0088] Acquisition unit 42 is used to acquire the weld side shape of the current coil and the previous coil;

[0089] The judgment unit 43 is used to determine whether the current strip steel meets the preset online adjustment strategy for cutting edge based on the shape of the weld side, the cutting amount of the current strip steel, and the actual thickness of the current strip steel.

[0090] The adjustment unit 44 is used to adjust the feed rate of the cutting shear online when it is determined that the online adjustment strategy of the cutting shear is triggered, based on whether the current strip steel meets the preset online adjustment strategy of the cutting shear.

All apparatuses used in the methods of the embodiments of this invention fall within the scope of protection of this invention.

[0092] In practical applications, the continuous annealing production line has an average hourly output of 100 tons, with a profit of 600 yuan per ton. Using the edge-cutting shear control method provided in this embodiment can increase the average speed of the continuous annealing furnace area by 2%, and this function can be used for an average of one hour per day. The annual benefits that can be generated after adopting this control scheme are calculated as follows:

[0093] 100 tons / hour × 2% × 1 hour × 600 yuan / ton × 365 days / year = 438,000 yuan / year.
