[0042] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

[0043] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0044] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The embodiments will be described in detail below with reference to the accompanying drawings.

[0045] A Hot Metal Detector (HMD) is a photoelectric detection device used to identify the leading edge and direction of hot metal movement. It utilizes a thermopile sensor as the detection element, combined with the imaging principle of a germanium lens, to achieve hot metal detection.

[0046] F1E, finishing mill vertical roller, that is, the finishing mill front vertical roller mill, is attached in front of the F1 finishing mill. Its main function is to further control the strip width.

[0047] F1~F7, finishing mill stands.

[0048] CS, flying shear, is a shearing machine that transversely cuts running rolled products. It is a processing equipment that can quickly cut iron plates, steel pipes, and paper rolls. It is a fixed-length shearing machine for the metallurgical steel rolling industry, high-speed wire and rebar, and is a product in modern rolled bar shearing.

[0049] Under the national energy conservation and emission reduction policy, steel mills focus on improving product efficiency, that is, producing the most products with the lowest consumption. For a conventional hot rolling production line, improving the rolling rhythm becomes the key to achieving a breakthrough in production and reducing consumption of the entire production line. Figure 1 The tracking zone before optimization is shown in the figure. The finishing rolling entrance tracking zone FMEZ and the finishing rolling tracking zone FMZ are divided by F1. The FMEZ includes two partitions (such as Figure 2 (As shown in the figure, the tracking zones before optimization are as follows): the hot coil box HMD01 to the flying shear constitutes the flying shear entry tracking zone (CSEZ), while the flying shear to F1 constitutes the fine descaling zone (FSB). The FSB tracking zone extends from the flying shear to F1, covering a distance of 10.88m. Slabs cannot remain stationary before the hot coil box HMD01 hot inspection. Slabs must wait until the slab shadow is clear in the FSB tracking zone at the finishing mill entrance, meaning that the finishing mill F1 is unloaded. Only then can the next slab enter the finishing mill entrance tracking zone. The minimum interval between the two slabs is 17 seconds. Due to the unreasonable division of tracking zones for steel feeding conditions and speed settings, the rolling rhythm is significantly restricted. Under the current tracking zone configuration, the interval between the two slabs is too long, hindering further efficiency improvements. To shorten the interval between slabs in the finishing mill and further improve the rolling rhythm, optimization of the finishing mill entrance tracking zone and the finishing mill tracking zone is required.

[0050] To address the above problems, based on the study of finishing rolling tracking zoning, combined with a large amount of rolling data statistical analysis and field experiments, a method for optimizing finishing rolling tracking zoning and improving rolling rhythm is proposed within the capacity of existing rolling mill equipment.

[0051] In order to solve the problems of the prior art, the embodiments of the present application provide a steel rolling system control method, device, equipment, storage medium and program product. The steel rolling system control method provided by the embodiments of the present application is first introduced below.

[0052] Figure 3 The following is a flow chart of a steel rolling system control method provided by an embodiment of the present application. The method includes the following steps:

[0053] S301, when detecting that a first rolled piece enters a first tracking area, obtaining real-time position data of the first rolled piece, and preventing a second rolled piece from entering the first tracking area.

[0054] The first tracking area is the area between the hot coil box and the vertical roller, and the second rolled piece is the rolled piece to be rolled after the first rolled piece.

[0055] The vertical rollers here can be finishing mill vertical rollers.

[0056] The real-time position of the first rolled piece can be monitored by setting up a hot metal detector. Specifically, a hot metal detector can be set at the starting position of the first tracking area, that is, the hot coil box position. When the hot metal detector detects the first rolled piece, it indicates that the first rolled piece has entered the first tracking area. At this time, the position of the first rolled piece in the first tracking area can be tracked in real time.

[0057] S302, when it is determined based on the real-time position data that the tail of the first rolled piece leaves the vertical roller, controlling the second rolled piece to enter the first tracking area.

[0058] Specifically, when the detected real-time position data of the first rolled piece indicates that the tail of the first rolled piece has left the vertical roller (that is, the first rolled piece has completed unloading at the vertical roller), there is no material in the first tracking area at this time. Therefore, the second rolled piece is controlled to enter the first tracking area and the rolled piece is continuously rolled.

[0059] In specific implementation, steps S301 to S302 can be applied to a hot rolling production line, but can also be applied to other production lines, which is not limited in the embodiment of the present application.

[0060] This embodiment proposes a method for controlling a steel rolling system. Upon detecting that a first workpiece has entered a first tracking zone, the system acquires the first workpiece's real-time position data and prevents a second workpiece from entering the first tracking zone. The first tracking zone is the area between the hot coil box and the vertical rollers, and the second workpiece is the workpiece to be rolled after the first workpiece. Upon determining, based on the real-time position data, that the tail of the first workpiece has left the vertical rollers, the second workpiece is controlled to enter the first tracking zone. This allows the next workpiece to enter the first tracking zone as soon as the previous workpiece has been unloaded from the vertical rollers, shortening the rolling gap between workspieces and improving rolling efficiency.

[0061] Specifically, if Figure 4 As shown in the figure, taking the 7-stand irreversible four-high finishing mill configured in the hot rolling production line as an example, the zoning of the finishing mill entrance tracking area is optimized, and the boundary point between the finishing entrance tracking area FMEZ (i.e., the first tracking area) and the finishing tracking area FMZ is changed from F1 to the finishing vertical roll F1E, and the condition for steel feeding at the finishing entrance is changed from F1 unloading to vertical roll F1E unloading. By adjusting the size of the tracking area, the function of early steel feeding is realized.

[0062] In some embodiments, in S302, before preventing the second rolled piece from entering the first tracking area, the steps may include:

[0063] When it is determined based on the real-time position data that the tail of the first rolled piece passes through the hot coil box, obtaining a gap between the tail of the first rolled piece and the head of the second rolled piece;

[0064] Preventing the second rolled piece from entering the first tracking area includes:

[0065] When the gap along the transport direction of the rolled piece is smaller than the length of the first tracking area, if the head of the second rolled piece reaches the hot coil box, the hot coil box is controlled to prevent the second rolled piece from passing through.

[0066] Specifically, when it is detected that the tail of the first rolled piece passes through the hot coil box, the gap between the tail of the first rolled piece and the head of the second rolled piece is obtained. If the gap is less than the length of the first tracking area along the direction of transmission of the rolled piece, it means that the second rolled piece may have reached the position of the hot coil box before the first rolled piece leaves the first tracking area. Therefore, if the first rolled piece already exists in the first tracking area, the hot coil box is controlled to prevent the second rolled piece from passing.

[0067] In some embodiments, after obtaining the gap between the tail of the first rolled piece and the head of the second rolled piece, the following steps may also be performed:

[0068] When the first width of the gap along the transport direction of the rolled piece is greater than the second width of the first tracking area, the relative transport speed between the first rolled piece and the second rolled piece is adjusted so that the head of the second rolled piece can reach the hot coil box before the tail of the first rolled piece leaves the first tracking area;

[0069] Preventing the second rolled piece from entering the first tracking area includes:

[0070] When the head of the second rolled piece reaches the hot coil box, the hot coil box is controlled to prevent the second rolled piece from passing through.

[0071] Specifically, when the first width of the gap along the workpiece transmission direction is greater than the second width of the first tracking area, it means that when the first workpiece leaves the first tracking area, the second workpiece may not have reached the position of the hot coil box. At this time, there may be no material in the first tracking area for a long time, resulting in a waste of resources. Therefore, in order to avoid an excessively large gap between the first and second workpieces, the second workpiece needs to be accelerated so that when the first workpiece leaves the first tracking area, the second workpiece can reach the hot coil box position, thereby minimizing the rolling gap between the first and second workpieces and further improving the rolling efficiency.

[0072] In some embodiments, adjusting the relative transport speed between the first workpiece and the second workpiece includes:

[0073] Get the width difference between the first width and the second width;

[0074] Based on the width difference, the target relative transmission speed is determined;

[0075] The transmission speed of the second rolled piece is adjusted to increase from the first transmission speed to the second transmission speed, and the difference between the second transmission speed and the first transmission speed is the target relative transmission speed.

[0076] The first width is the distance between the first rolled piece and the second rolled piece, and the second width is the width of the first tracking area, that is, the distance between the hot coil box and the vertical roller.

[0077] Specifically, when it is detected that the tail of the first rolled piece passes through the hot coil box, the distance difference (i.e., the width difference) between the first width (the distance between the first rolled piece and the second rolled piece) and the second width (the width of the first tracking area) is obtained, and the transmission speed of the second rolled piece is adjusted from the first transmission speed to the second transmission speed to reduce the distance between the first rolled piece and the second rolled piece; when the distance between the first rolled piece and the second rolled piece is reduced until the distance between the first rolled piece and the second rolled piece (the first width) is no greater than the width of the first tracking area (the second width), the second rolled piece arrives at the hot coil box when the first rolled piece leaves the first tracking area. At this time, the second rolled piece can immediately enter the first tracking area, so that the first rolled piece and the second rolled piece are just connected, so that the steel rolling operation can be carried out continuously in the first tracking area, thereby improving the steel rolling efficiency.

[0078] In this embodiment, the first width between the first rolled piece and the second rolled piece can be reduced by controlling the moving speed of the second rolled piece.

[0079] For example, when the first width is L1, the second width is L2, the speed of the first workpiece is V1, and the speed of the second workpiece is V2, the adjustable speed of the second workpiece can be calculated using formula (1): ΔV = (L1-L2) / (L2 / V1), which means that the speed of the second workpiece can be increased by ΔV.

[0080] In some embodiments, in the above S302, when it is determined based on the real-time position data that the tail of the first rolled piece has left the vertical roller, controlling the second rolled piece to enter the first tracking zone may include:

[0081] When the real-time position data indicates that the tail of the first rolled piece has left the vertical roller, the vertical roller is controlled to open;

[0082] When the vertical rolls are opened, the hot coil box is controlled to be ready so that the second rolled piece passes through the hot coil box and enters the first tracking area.

[0083] Specifically, after the tail of the first workpiece is unloaded by the vertical rollers, the vertical roller gap closes. Due to the vertical rollers' head avoidance function, the vertical rollers' APC action causes finishing mills to be unready, preventing the second workpiece from passing through the hot coil box. Therefore, the control conditions of the rolling system need to be modified. After the tail of the first workpiece is unloaded by the vertical rollers, the vertical rollers are controlled to open. When the vertical rollers are open, it indicates that the finishing mill is ready for rolling. At this time, the hot coil box allows the second workpiece to pass through and enter the first tracking zone. Compared to the prior art, where the first workpiece must be unloaded at F1 before the second workpiece can pass through the hot coil box, the control method provided in the embodiment of the present application only requires modifying the control method of the rolling system to achieve the second workpiece entering the first tracking zone in advance, shortening the rolling gap and reducing costs.

[0084] In one embodiment, if Figure 4 As shown, new correction conditions for the head and tail areas are established. The head of F1 loading is moved into the finishing area, and the head of finishing vertical roll F1E loading is changed to move into the finishing area; the tail of F1 unloading is moved out of the finishing entrance area, and the tail of finishing vertical roll F1E unloading is changed to move out of the finishing entrance area. The slab is unloaded at the finishing vertical roll F1E, triggering the APC action. The vertical roll gap is opened by 20mm, avoiding the slab being blocked at the hot coil box HMD01.

[0085] In some embodiments, the first tracking area includes a second tracking area and a third tracking area, the second tracking area is the area between the hot coil box and the flying shear, and the third tracking area is the area between the flying shear and the vertical roller;

[0086] In the above S302, when it is determined based on the real-time position data that the tail of the first rolled piece has left the vertical roller, controlling the second rolled piece to enter the first tracking area may further include:

[0087] When the real-time position data indicates that the tail of the first rolled piece leaves the vertical roller and there is no material in the third tracking area, the flying shear is controlled to be ready to allow the second rolled piece to pass through the flying shear.

[0088] Specifically, the steel rolling system includes a flying shear between the hot coil box and the vertical rollers, so the first tracking zone also includes the second and third tracking zones. In existing control methods, the ready condition for activating the flying shear head requires that the first rolled piece be unloaded at F1 and that there is no material tracking within the third tracking zone. To further optimize the control method of this application, the flying shear is controlled to be ready when the tail of the first rolled piece is unloaded at the vertical rollers, that is, when the tail of the first rolled piece leaves the vertical rollers, and there is no material tracking within the third tracking zone, allowing the second rolled piece to pass through the flying shear.

[0089] In one example, if Figure 5As shown, the ready condition for the flying shear head to start is changed to unloading the finishing vertical roll F1E, and the flying shear head interlocking condition is ready. The finishing descaling area FSBZ is adjusted from flying shear to F1 to flying shear to finishing vertical roll F1E, and the F1 tracking area F1Z is adjusted from F1 to F2 to finishing vertical roll F1E to F2.

[0090] Based on the steel rolling system control method provided in the above embodiment, the present application also provides a specific implementation of the steel rolling system control method. Please refer to the following embodiment.

[0091] This embodiment discloses a method for optimizing finishing rolling area tracking of a 2250 hot rolling production line to achieve early steel feeding, shorten the interval time, and improve the rolling rhythm and rolling efficiency.

[0092] (1) Re-divide the finishing and finishing entrance areas, and adjust the FSBZ and F1Z tracking area ranges, boundary points, and corresponding chain conditions. Adjust the finishing entrance area FMEZ from HMD01 to F1 to HMD01 to finishing vertical roll F1E, adjust the finishing area FMZ from F1 to F7 to finishing vertical roll F1E to F7, adjust the descaling area FSBZ from flying shear to F1 to flying shear to finishing vertical roll F1E, and adjust the F1 tracking area from F1 to F2 to finishing vertical roll F1E to F2.

[0093] (2) Establish new correction conditions for the head and tail areas. Instead of the F1 loading head moving into the finishing area, the finishing vertical roller F1E loading head moving into the finishing area is changed; instead of the F1 unloading tail moving out of the finishing entrance area, the finishing vertical roller F1E unloading tail moving out of the finishing entrance area is changed.

[0094] (3) After the finishing vertical roller F1E is unloaded and the tail moves out of the FSB tracking area, the corresponding tracking positions are all reset to zero, and the position of the tail between the finishing vertical rollers F1E and F1 is calculated by using the finishing entrance synchronous speed integral.

[0095] (4) When the tail is unloaded at F1, the head of the finishing vertical roll F1E avoids the function, and the roll gap of the vertical roll opens 20mm. The APC action of the finishing vertical roll F1E causes the finishing rolling to be unready, resulting in the slab being prohibited at the hot coil box HMD01. By modifying the finishing vertical roll F1E to unload, the APC action is triggered, and the roll gap of the vertical roll opens 20mm, avoiding the prohibition of the slab at HMD01.

[0096] (5) The ready condition for the flying shear head to start requires that F1 is unloaded and there is no material tracking in the fine descaling area FSBZ. After tracking optimization, due to the unloading of the vertical roller F1E, the tail leaves the FSBZ area. At this time, the next slab is fed into the steel, but because F1 has not yet been unloaded, the flying shear head does not cut. The condition is modified to the unloading of the finishing vertical roller F1E, and the interlocking condition of the flying shear head is ready.

[0097] (6) When the fast steel feeding mode is put into use, the shortest interval time for finishing rolling reaches 12.55s, that is, the shortest interval time from unloading the previous piece of steel F1 to loading the next piece of steel F1 is 12.55s.
