[0051] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

In addition, in order to facilitate the clear description of the technical solution of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and the like are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not limit them to be necessarily different.

[0053] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0054] Figure 1 A schematic diagram of a hot rolling production line applicable to a hot rolling production line control method provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the hot rolling production line applicable to the present application includes a roughing mill and a finishing mill, between which a plurality of sequentially connected rollers RX1, RX2, FE3, FE2 and FE1 are arranged, and on both sides of the connecting point are the roughing rolling area (RX1 and RX2) and the waiting rolling area (FE3, FE2 and FE1), respectively. It can be understood that the number of rollers in the figure is only for illustration and is not a sole limitation.

[0055] In actual production, the roller table turns from the roughing mill to the finishing mill, and the head and tail of the steel billets to be batched (the front end is the head end, and the back end is the tail end) pass through the billet connection point in turn and enter the rolling area to be rolled, completing the reading of the information of the steel billets to be batched to form the steel billets to be rolled.

[0056] Figure 2A schematic diagram of a hot rolling production line applicable to another hot rolling production line control method provided in an embodiment of the present application, wherein a cooling device is added to the rough rolling area, and the billets need to be cooled. After cooling, some rollers need to be left to output the cooled billets, thereby compressing the space between the original rough rolling mill and the finishing mill for storing the intermediate billets (i.e., the billets rolled in batches in the figure). In view of this, the present application proposes a hot rolling production line control method to at least solve the above technical problems.

[0057] Figure 3 A schematic flow chart of a hot rolling production line control method provided in an embodiment of the present application, such as Figure 3 As shown, including:

[0058] S110, in response to the detection instruction, determining whether the cooling device is in use.

[0059] S120, when the cooling device is in use, the position of the connecting point is adjusted toward the area to be rolled, so as to form a cooling output roller table between the rough rolling area and the area to be rolled.

[0060] S130, cooling the steel billet by a cooling device, and outputting the cooled steel billet to a cooling output roller.

[0061] S140, identifying the steel billet on the cooling output roller table through the billet connection point, and completing the handover of the steel billet information.

[0062] A hot rolling production line control method provided in an embodiment of the present application, when a cooling device of the production line is put into use, adjusts the position of the billet connection point, and can use the cooling output roller behind the cooling device to identify the billet, thereby ensuring the space to be rolled without increasing the roller or expanding the production line area. In this way, for some production lines that are later equipped with cooling devices or need to process longer billets, the rolling rhythm of the production line can be maintained.

[0063] Since the cooling device may be put into use or not, the hot rolling production line control method provided in this application can be processed in different ways for the two situations. Figure 4 A schematic flow chart of another hot rolling production line control method provided in an embodiment of the present application, Figure 5 A schematic diagram of a production line flow chart of a hot rolling production line control method without using a cooling device provided in an embodiment of the present application, Figure 6 A schematic diagram of a production line flow diagram of a hot rolling production line control method provided in an embodiment of the present application and a cooling device. Figure 4As shown, after necessary preparations, S01 is used to collect the rolling status of the finishing mill, such as whether the working status is normal, whether there are workpieces to be processed, etc., and then S02 is used to determine whether the cooling device is put into use. Based on whether it is put into use, it is divided into two parts. One part is A01, A02, A03, A04, A05, A06, and A07, which are related to the processing process when the cooling device is put into use, corresponding to Figure 6 The other part is B01, B02, B03, B04, B05, B06, B07 involving the processing process when the cooling device is not put into use, corresponding to Figure 5 , the hot rolling production line control method provided in the embodiment of the present application is introduced below in conjunction with the accompanying drawings.

[0064] According to some embodiments, before the cooling device, the rough rolling area is provided with at least one rough rolling output roller table, and the above step S110 may include:

[0065] In response to the detection instruction, the residence time of the steel billet on at least one rough rolling output roller is determined. When the residence time reaches a preset value, it is determined that the cooling device is in use; when the residence time is less than the preset value, it is determined that the cooling device is not in use.

[0066] For example, Figure 4 In S02, if there is no cooling device in use, the steel billets to be batched in the rough rolling area will not stay for too long, and will directly follow the roller to enter the waiting rolling area, and will be scanned by the billet connection point to be converted into steel billets for batch rolling. In the case where the cooling device is in use, since the billets need to be cooled, the billets often need more time to stay in the rough rolling area. Therefore, the billets in front of the cooling device (near the rough rolling mill side) are also detained. Therefore, it can be judged by judging the residence time of the billets on the rough rolling output roller in front of the cooling device. When the residence time reaches the preset value, it can be judged that the cooling device is in use. Otherwise, the cooling device is not in use. The setting of the specific preset time can be set according to the cooling time of the cooling device, and is not specifically limited.

[0067] According to some embodiments, the hot rolling production line control method further includes: when the cooling device is not in use, the position of the billet connection point is kept unchanged, and the billet on the roller in the rough rolling area is identified by the billet connection point to complete the handover of the billet information.

[0068] For example, Figure 4 and Figure 5 As shown, if it is determined in S02 that the intermediate cooling device is not put into use, the process proceeds to steps B01 to B07. Figure 5As shown in (a), the billet connection point is at position 1, namely, billet connection point 1, and its two sides are respectively the rough rolling area (RX1, RX2) and the waiting area (FE3, FE2, FE1). When there is a billet in RX2, namely, waiting batch 1, the roller conveyor is started to transport the billet, and the billet connection point is scanned with the roller conveyor. After scanning, waiting batch 1 enters FE3 of the waiting area, namely, Figure 5 In (b), batch 4, correspondingly, as the roller table turns to, the positions of batch 3, batch 2 and batch 1 of the steel billet previously scanned will move back. In this way, the information of the steel billet processed by the roughing mill is completed to wait for the rolling in the finishing mill.

[0069] In some examples, the step of identifying the steel billet on the roller in the rough rolling area through the steel billet connection point and completing the steel billet information handover may include:

[0070] Determine whether the end of the steel billet in the rough rolling area close to the billet joining point has reached the billet joining point.

[0071] If the billet connection point is reached, the roller table is controlled to rotate so that the billet enters the rolling area until the other end of the billet reaches the billet connection point.

[0072] For example, Figure 5 As shown in (a) and (b), when one end of batch 1 close to joining point 1 reaches joining point 1, the roller is controlled to rotate, batch 1 moves forward, and joining point 1 scans batch 1 until the other end of batch 1 also reaches the position of joining point 1, indicating that the transfer of billet information is completed.

[0073] When the cooling device is put into use, Figure 4 and Figure 6 As shown, the processing process of steps A01 to A07 is entered. The roller information of RX1 is collected through A01 to A02 to determine whether there is a steel billet to be cooled on RX1 ( Figure 6 In the step (a) of waiting for cooling 1), when there is a steel billet on RX1, it is necessary to reserve a cooling output roller on the original roller for temporarily storing the cooled steel billet to be batched. According to some embodiments, the above step S120 may include:

[0074] When the cooling device is put into use, the length of the steel billet to be cooled is determined.

[0075] The position of the billet connection point is adjusted toward the area to be rolled to form a cooling output roller conveyor between the rough rolling area and the area to be rolled, and the length of the cooling output roller conveyor is greater than the length of the billet to be cooled.

[0076] For example, the length of the billet to be cooled can be determined by recording or on-site measurement, and after the determination, the billet connection point is adjusted from position 1 to position 2, that is, Figure 6As shown in the middle billet connection point 2, the position difference between the two forms a cooling output roller, the length of which is greater than the length of the billet to be cooled to ensure that the billet is completely placed. Figure 4 As shown in A03, the rotating roller moves the steel billet in the original rolling area toward the finishing mill to vacate the cooling output roller. Figure 6 As shown in (a) to (b), the position of the connecting point is adjusted to use FE3 as the cooling output roller, and the roller is turned to move batch rolling 3, batch rolling 2 and batch rolling 1 to FE2 and FE3.

[0077] It should be noted that the adjustment of the position of the blank joining point in the embodiment of the present application can move the original position to a new position, or add a new blank joining point at the new position.

[0078] After the cooling output roller is cleared, the billet to be cooled can be cooled and output to the cooling output roller after cooling. Figure 6 As shown in (c).

[0079] After cooling, the steel billet is scanned. The above step S140 may include:

[0080] Determine whether the end of the billet on the cooling output roller table close to the billet connection point has reached the billet connection point;

[0081] If the billet connection point is reached, the roller table is controlled to rotate so that the billet enters the rolling area until the other end of the billet reaches the billet connection point.

[0082] For example, based on Figure 4 A05 and A06, such as Figure 6 As shown in (c), the cooled billet (cold end 1) is waiting for the connection point scanning on the cooling output roller FE3. When the end of the cold end 1 on FE3 close to the connection point 2 reaches the position of the connection point 2, the roller is controlled to rotate, and the information of the cold end 1 is transferred through the connection point 2 to form Figure 6 (d) batch rolling 4.

[0083] After the information transfer of the steel billet is completed, in order to prevent the steel billet from being stationary and damaging the roller, in some examples, the following processing can be performed: after the information transfer of the steel billet is completed, the steel billet on the output roller and the roller in the rolling area is swung to cool down to prevent the steel billet from being stationary.

[0084] For example, Figure 4 As shown, after the steel billet has been delivered through A01 to A06 or BO1 to B06, the rollers FE3, FE2, and FE1 in the rolling area can continue to swing to prevent the steel billet that has just been processed by the rough rolling mill from being stationary and scalding the rollers.
