[0032] 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 only to provide a better understanding of the present application by illustrating the examples of the present application.

[0033] It should be noted that, in this article, relational terms such as target and preset are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "include..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0034] In the process of steel finishing rolling, the steel needs to be transferred to the rolling mill through rollers under high temperature and high speed conditions, and the steel is rolled by the rolling mill to obtain strip steel. In the process of steel finishing rolling, multiple rolling mills can be used to continuously roll the strip steel so that the strip steel can achieve the required shape, size and performance.

[0035] During the hot rolling process of strip steel, due to various reasons such as operating environment, equipment status, raw material quality and improper process control, impurities and pollutants such as scale, iron oxide, fine particles (such as dust), grease residue and other types of impurities and pollutants are pressed into the surface or deeper inside of the strip steel, affecting the quality and performance of the steel.

[0036] It is understandable that the impact of impurities and contaminants on the strip is multifaceted. For example, in terms of appearance, impurities and contaminants may reduce the surface finish of the strip and affect the aesthetics of the strip; in terms of physical properties, impurities and contaminants may cause the mechanical properties of the strip to decline, including strength, toughness and other indicators; in terms of service life, impurities and contaminants may easily cause cracks, corrosion and other problems during subsequent processing and use, shortening the service life. Furthermore, the many adverse effects of impurities and contaminants on the strip may lead to product downgrades, returns and other problems, and even legal disputes, seriously affecting the company's economic benefits and market competitiveness. Therefore, reducing the problem of impurities and contaminants being pressed into the strip during the finishing rolling process plays an important role in improving the quality and performance of the strip.

[0037] In the related art, during the finish rolling of the strip steel, the impurities and pollutants pressed in can be controlled by adding side spray sweeping devices, improving dust removal equipment, strengthening rolling mill cleaning, and improving water quality.

[0038] Figure 1 A schematic diagram of a rolling mill provided by an embodiment of the present application is shown. Figure 1 As shown, the rolling mill 10 includes a main body 11, a transverse spray device 12 and a side spray device 13. Among them, the main body 11 can be used to roll the steel to be processed, thereby reducing the thickness of the steel to be processed; the transverse spray device 12 and the side spray device 13 can be used to remove impurities and pollution from the steel to be processed. It can be understood that during the rolling process of the steel to be processed, its surface will react with the oxygen in the air to form iron oxide scale. Therefore, the transverse spray device 12 and the side spray device 13 can be set to spray water mist or oil mist on the surface of the hot-rolled steel to form a protective film, which effectively reduces the direct contact between the steel and oxygen, thereby reducing the generation of oxide scale. At the same time, the transverse spray device 12 and the side spray device 13 can also help remove the oxide scale and other pollutants that have been attached to the surface of the steel, such as oil stains, dust, etc., to further improve the surface quality of the steel.

[0039] However, for rolling mills with different rolling specifications, the situations of impurities and contaminants being pressed into the steel strip are different. In the related art, controlling the impurity removal device with the same control strategy cannot effectively reduce the problem of impurities and contaminants being pressed into the steel strip. Therefore, how to control the impurity removal device to reduce the problem of impurities and contaminants being pressed into the steel, thereby ensuring the quality and performance of the steel, is a technical problem that needs to be solved urgently by related technicians.

[0040] In order to solve the problems of the prior art, the embodiments of the present application provide a control method, device, equipment and computer storage medium for a dust removal device. The control method for a dust removal device provided in the embodiments of the present application is first introduced below.

[0041] Figure 2 The schematic diagram of the control method of the dust removal device provided by one embodiment of the present application is shown. The dust removal device includes dust removal devices corresponding to multiple rolling mills for hot rolling of the steel to be processed. Figure 2 As shown, the control method of the dust removal device includes the following steps:

[0042] S210, determining a target dust removal timing control strategy corresponding to the steel to be processed according to the rolling specifications of the steel to be processed and a preset corresponding relationship.

[0043] S220: Calculate the corresponding opening time of each dust removal device based on the target dust removal timing control strategy.

[0044] S230, controlling the corresponding dust removal device according to the opening time.

[0045] For example, multiple rolling mills can be arranged in sequence, and the rolling specifications of each rolling mill are gradually reduced, so that the steel to be processed can be gradually rolled into the rolling specifications required by the user after passing through each rolling mill in sequence. In one example, the user needs a steel with a thickness of 2 millimeters (mm), and the thickness of the steel to be processed, that is, the steel to be rolled, is 5 centimeters (cm). In the process of passing through the rolling mills in sequence, the thickness of the steel to be processed gradually becomes thinner, and finally the steel with the thickness required by the user is obtained.

[0046] In some embodiments, in S210, the target dust removal timing control strategy corresponding to the steel to be processed can be determined according to the rolling specifications of the steel to be processed and the preset corresponding relationship. The preset corresponding relationship includes the rolling specification conditions corresponding to different dust removal timing control strategies, and the target dust removal timing control strategy is at least one of the different dust removal timing control strategies.

[0047] For example, the rolling specification is used to characterize the specifications of the steel required by the user. That is, after the steel to be processed is subjected to hot continuous rolling, the steel with the rolling specification is finally obtained.

[0048] For example, the dust removal timing control strategy can be used to control the dust removal device corresponding to each rolling mill in the hot rolling process. The dust removal device corresponding to each rolling mill can include a horizontal spray device and / or a side spray device.

[0049] Exemplarily, different dust removal timing control strategies may be determined for different rolling specification conditions, and the correspondence between the different rolling specification conditions and each dust removal timing control strategy may be used as a preset correspondence.

[0050] After obtaining the rolling specifications corresponding to the steel to be processed, the rolling specification conditions satisfied by the rolling specifications of the steel to be processed can be determined, and the dust removal timing control strategy corresponding to the rolling specification conditions can be determined according to the preset corresponding relationship, and the dust removal timing control strategy can be used as the target dust removal timing control strategy.

[0051] In some optional embodiments, the rolling specifications include at least a rolling thickness parameter. Figure 3 FIG. 2 shows a flow chart of S210 provided by an embodiment of the present application. Figure 3 As shown, S210 includes the following steps:

[0052] S211. Determine the target rolling specification conditions that the rolling thickness parameters satisfy.

[0053] S212: Determine a target dust removal timing control strategy corresponding to the target rolling specification condition from a preset corresponding relationship.

[0054] It is understandable that the relevant technicians have obtained a large amount of experimental data through experiments and tests, and through analysis of the experimental data, have determined that when the steel to be processed is rolled into different thicknesses, the rework rate caused by impurities and contaminants being pressed into the steel is different. That is, the relevant technicians have determined that the rolling thickness of the steel to be processed has a greater impact on the problem of impurities and contaminants being pressed into the steel.

[0055] Therefore, different dust removal device control strategies can be adopted for different rolling thicknesses, thereby reducing the problem of impurities and pollutants being pressed into steel and improving the quality and performance of steel.

[0056] In some embodiments, in S211, relevant technicians can determine the relationship between the impurities and pollutants pressed into the steel and the rolling thickness through data analysis, so as to determine different rolling specification conditions.

[0057] Furthermore, from a plurality of determined rolling specification conditions, a rolling specification condition satisfied by the rolling thickness parameter may be determined as a target rolling specification adjustment condition.

[0058] According to the situation of impurities and pollutants being pressed into steel under different rolling thicknesses, different rolling thicknesses can be divided to obtain different rolling thickness intervals, and different rolling thickness intervals can be used as different rolling specification conditions. Among them, different rolling thickness intervals can reflect the situation of different impurities and pollutants being pressed into steel. Furthermore, according to the rolling thickness parameters corresponding to the steel to be processed, the rolling thickness interval in which it is located can be determined.

[0059] In one example, when the rolling thickness is less than 3mm, it can be determined that the repair rate caused by impurities and contaminants being pressed into the steel is low; when the rolling thickness is between 3mm and 6mm, it can be determined that the repair rate caused by impurities and contaminants being pressed into the steel is moderate; when the rolling thickness is greater than 6mm, it can be determined that the repair rate caused by impurities and contaminants being pressed into the steel is high. Furthermore, different rolling specification adjustment conditions can be determined for different rolling thickness intervals.

[0060] In some embodiments, in S212, a target dust removal timing control strategy corresponding to the target rolling specification condition may be determined from a preset correspondence.

[0061] Exemplarily, different rolling specification conditions correspond to different dust removal timing control strategies. The target dust removal timing control strategy corresponding to the target rolling specification condition can be determined from the preset corresponding relationship.

[0062] In one example, when the target rolling specification condition is a target thickness interval among multiple rolling thickness intervals, a target dust removal timing control strategy corresponding to the target thickness interval may be determined.

[0063] In an embodiment of the present application, when the rolling specification is the rolling thickness parameter, different rolling specification conditions can be constructed according to different rolling thickness intervals, and the rolling specification conditions satisfied by the rolling thickness parameters corresponding to the steel to be processed can be determined, so as to determine the dust removal timing control strategy for the rolling thickness parameters corresponding to the steel to be processed, that is, the target dust removal timing control strategy.

[0064] Exemplarily, different dust removal timing control strategies may also include the purge intensity of the dust removal device. In one example, the control of different purge intensities may be achieved by setting the spray intensity of water mist or oil mist.

[0065] In some embodiments, in S220, the opening time corresponding to each dust removal device may be calculated based on the target dust removal timing control strategy.

[0066] For example, the opening time corresponding to each dust removal device may be calculated according to the determined target timing control strategy, wherein the opening time corresponding to different dust removal devices may be different.

[0067] In some embodiments, in S230, the corresponding dust removal device may be controlled according to the opening time.

[0068] For example, a control signal may be sent to the dust removal device at the start time so that the dust removal device is turned on to spray water mist or oil onto the steel material to be processed.

[0069] In one example, when the horizontal spray device and / or the side spray device receives an on signal, it starts spraying water mist or oil onto the steel to be treated.

[0070] In the embodiment of the present application, the target dust removal timing control strategy corresponding to the steel to be processed is determined by the rolling specifications of the steel to be processed and the preset corresponding relationship, and the corresponding opening time of each dust removal device is calculated according to the target dust removal timing control strategy, so as to realize the control of each dust removal device. It can be understood that in the embodiment of the present application, different dust removal timing control strategies are adopted for the steel to be processed with different rolling specifications to realize the control thereof, so as to reduce the impurities and pollutants pressed in during the finishing rolling process, thereby ensuring the quality and performance of the steel.

[0071] Furthermore, in order to determine the opening time corresponding to each dust removal device, as another implementation method of the present application, the present application also provides another implementation method of the control method of the dust removal device, please refer to the following embodiments for details.

[0072] Figure 4 FIG. 2 is a flow chart of a control method for a dust removal device provided in another embodiment of the present application. The dust removal device includes dust removal devices corresponding to multiple rolling mills for hot rolling of the steel to be processed. Figure 4As shown, the control method of the dust removal device includes the following steps:

[0073] S410, determining a target dust removal timing control strategy corresponding to the steel to be processed according to the rolling specifications of the steel to be processed and a preset corresponding relationship.

[0074] S420, in response to detecting that the steel to be processed arrives at the flying shear position, determining the dust removal opening position information corresponding to each dust removal device according to the target dust removal timing control strategy.

[0075] S430, obtaining the speed of the steel to be processed.

[0076] S440, calculating the opening time for the steel to be processed to reach the dust removal opening position according to the speed and the dust removal opening position information.

[0077] S450, controlling the corresponding dust removal device according to the opening time.

[0078] Exemplarily, step S410 is consistent with step S210, and step S450 is consistent with step S230, which will not be described in detail here.

[0079] In some embodiments, in S420, when it is determined that the steel to be processed reaches the flying shear position, the dust removal opening position information corresponding to each dust removal device can be determined according to the target dust removal timing control strategy.

[0080] For example, the shear position can be used to indicate that the steel to be processed has entered the hot rolling area. Therefore, judging whether the steel to be processed has reached the shear position can be used as a trigger condition for calculating the opening time. This ensures that the opening time of each dust removal device is calculated at an appropriate time, and while ensuring that the dust removal device can be opened according to the opening time, it avoids wasting computing resources.

[0081] For example, after detecting that the steel material to be processed has arrived at the flying shear position, the flying shear may feed back a flying shear occupancy signal to indicate that the steel material to be processed has arrived at the flying shear position.

[0082] In one example, the shearing action signal of the flying shear may be used as a flying shear occupancy signal, that is, a compact strip production (CSP) start signal, that is, a CSP ON signal.

[0083] In another example, a hot metal detector (HMD) can be provided in a production line for rolling the steel to be processed, wherein the position of the HMD can be set by a technician in an area where the steel is hot-rolled according to different requirements, and the position of the HMD can be saved in a control system, which also stores the position information of the flying shear. The running speed of the steel to be processed in the roller is obtained, and then, according to the position of the HMD, the position information of the flying shear and the running speed, it is determined whether to generate a flying shear occupancy signal.

[0084] Exemplarily, different dust removal timing control strategies may correspond to different dust removal opening positions. It is understandable that for different dust removal transpositions, under the same dust removal timing control strategy, there may be different dust removal opening positions. And for the same dust removal device, under different dust removal timing control strategies, its corresponding dust removal opening positions may be different.

[0085] In some optional embodiments, the dust removal timing control strategy includes a first dust removal timing control strategy, a second dust removal timing control strategy and a third dust removal timing control strategy. The first dust removal timing control strategy, the second dust removal timing control strategy and the third dust removal timing control strategy may be dust removal timing control strategies corresponding to different rolling specifications. For example, the first dust removal timing control strategy may be a dust removal timing control strategy corresponding to a rolling specification with a rolling thickness of less than 3 mm; the second dust removal timing control strategy may be a dust removal timing control strategy corresponding to a rolling specification with a rolling thickness of 3 mm to 6 mm; the third dust removal timing control strategy may be a dust removal timing control strategy corresponding to a rolling specification with a rolling thickness greater than 6 mm. It can be understood that the division of rolling specifications in the embodiments of the present application is only for exemplary purposes, and the division of rolling specifications may also include a variety of situations, which are not listed one by one in the embodiments of the present application.

[0086] Figure 5 FIG. 4 shows a flow chart of S420 provided by an embodiment of the present application. Figure 5 As shown, S420 includes the following steps:

[0087] S421. Obtain rolling mill position information of n rolling mills arranged sequentially along the running direction of the steel to be processed, where n is a positive integer.

[0088] Exemplarily, n rolling mills may be sequentially arranged along the running direction of the steel to be processed, and the position information of the n rolling mills may be acquired respectively.

[0089] S422. When it is determined that the target dust removal timing control strategy is the first dust removal timing control strategy, the rolling mill position information of the nth rolling mill is used as the dust removal start position information of the dust removal device corresponding to the nth rolling mill.

[0090] In one example, when the target dust removal timing control strategy is determined to be the dust removal timing control strategy corresponding to the rolling specification with a rolling thickness less than 3 mm, the rolling mill position information of the nth rolling mill can be used as the dust removal start position information of the dust removal device corresponding to the nth rolling mill. That is, when the steel to be processed reaches the nth rolling mill, its corresponding dust removal device starts working.

[0091] S423. When it is determined that the target dust removal timing control strategy is the second dust removal timing control strategy, the rolling mill position information of the n-1th rolling mill is used as the dust removal start position information of the dust removal device corresponding to the nth rolling mill.

[0092] In one example, when the target dust removal timing control strategy is determined to be the dust removal timing control strategy corresponding to the rolling specification with a rolling thickness of 3mm to 6mm, the rolling mill position information of the n-1th rolling mill is used as the dust removal opening position information of the dust removal device corresponding to the nth rolling mill. That is, when the steel to be processed reaches the n-1th rolling mill, the dust removal device corresponding to the nth rolling mill is turned on. It can be understood that when the rolling thickness is 3mm to 6mm, the dust removal device corresponding to the previous stand can be turned on.

[0093] S424. When it is determined that the target dust removal timing control strategy is the third dust removal timing control strategy, the flying shear position is used as the dust removal opening position information corresponding to each dust removal device.

[0094] In one example, when the target dust removal timing control strategy is determined to be the dust removal timing control strategy corresponding to the rolling specification with a rolling thickness greater than 6 mm, the flying shear position is used as the dust removal opening position information corresponding to each dust removal device. That is, when it is detected that the steel to be processed reaches the flying shear position, each dust removal device can be turned on.

[0095] In an embodiment of the present application, the dust removal timing control strategy described in the target dust removal timing control strategy is determined to determine the dust removal opening position of each dust removal device, which can reduce impurities and pollutants pressed in during the finishing rolling process, thereby ensuring the quality and performance of the steel.

[0096] In some embodiments, in S430, the speed of the steel material to be processed may be obtained.

[0097] For example, the running speed corresponding to the steel material to be processed may be determined based on the speed of the roller.

[0098] In some embodiments, in S440, the opening time for the steel material to be processed to reach the dust removal opening position is calculated based on the speed and the dust removal opening position information.

[0099] Exemplarily, the running speed of the steel to be processed and the opening time of the dust removal opening position information can be calculated according to the kinematic formula, so as to determine the opening time when the steel to be processed reaches the dust removal opening position.

[0100] In one example, the opening time when the steel to be processed reaches the dust removal opening position can be calculated by the following formula (1):

[0101]

[0102] Among them, P can represent the dust removal start position information; P0 can represent the flying shear position information, that is, the position information corresponding to the trigger calculation start time; It represents the integration of the speed V from time t1 to time t, wherein time t1 may be the time information when the steel to be processed reaches the flying shear position, and t represents the opening time.

[0103] In an embodiment of the present application, the time information when the steel to be processed reaches the dust removal starting position information is determined by the dust removal starting position information determined by the target dust removal timing control strategy and the speed of the steel to be processed, and the time information is used as the starting time of the dust removal device. In this way, it can be ensured that each dust removal device can be turned on according to the calculated starting time, thereby reducing the problem of impurities and pollutants being pressed into the steel, thereby ensuring the quality and performance of the steel.

[0104] In order to ensure the accuracy of the opening time, as another implementation of the present application, the present application also provides another implementation of the control method of the dust removal device, please refer to the following embodiments for details.

[0105] Figure 6 FIG. 2 is a flow chart of a control method for a dust removal device provided in another embodiment of the present application. The dust removal device includes dust removal devices corresponding to multiple rolling mills for hot rolling of the steel to be processed. Figure 6 As shown, the control method of the dust removal device includes the following steps:

[0106] S610: Determine a target dust removal timing control strategy corresponding to the steel to be processed according to the rolling specifications of the steel to be processed and a preset corresponding relationship.

[0107] S620: Calculate the corresponding opening time of each dust removal device based on the target dust removal timing control strategy.

[0108] S630, controlling the corresponding dust removal device according to the opening time.

[0109] Exemplarily, steps S610-S630 are consistent with steps S210-S230, and will not be described in detail here.

[0110] S640. Obtain a detection signal, where the detection signal at least includes the detection position information corresponding to the detection device and the detection time information of the steel to be processed detected by the detection device.

[0111] Exemplarily, the detection signal at least includes at least one of the signal obtained based on a hot metal detector and the signal of biting the steel obtained based on a pressure sensor. That is, it can be understood that the signal obtained by the hot metal detector can be used as the detection signal; or the signal of biting the steel collected by the pressure sensor installed in the rolling mill can be used as the detection signal.

[0112] In one example, when the detection signal is the signal obtained by the hot metal detector, the detection signal may include the position information of the hot metal detector and the time information of the hot metal detector detecting the steel to be processed.

[0113] In another example, when the detection signal is the signal of biting the steel obtained by the pressure sensor, the detection signal may include the position information of the rolling mill and the time information of detecting the signal of biting the steel.

[0114] S650. In the case where the biting state of the target rolling mill is not detected at the opening time, correct the opening time corresponding to the first dust removal device according to the detection position information and the detection time information.

[0115] Wherein, the target rolling mill is the rolling mill where the dust removal device corresponding to the opening time is located, and the first dust removal device is the dust removal device corresponding to the rolling mill located after the target rolling mill among the multiple rolling mills arranged in sequence along the running direction of the steel to be processed.

[0116] Exemplarily, when the biting of the target rolling mill is not detected at the opening time, the opening time corresponding to the dust removal device of the rolling mill located after the target rolling mill can be corrected according to the detection position information and the detection time information.

[0117] In one example, when it is detected that the target rolling mill corresponding to the m-th rolling mill does not generate a signal of biting the steel, correct the opening times of the dust removal devices corresponding to the (m + 1)-th rolling mill, the (m + 2)-th rolling mill,..., the n-th rolling mill according to the detection position information and the detection time information. Wherein, m < n and m is a positive integer.

[0118] In some optional embodiments, the detection position information represents the distance information between the detection device and the flying shear, and the detection time information represents the moving time of the steel to be processed from the position of the flying shear to the detection device; the actual speed of the steel to be processed can be calculated according to the distance information and the moving time, and the opening time corresponding to the first dust removal device can be corrected according to the actual speed.

[0119] The actual speed of the steel material to be processed can be calculated by using the kinematic formula, distance information and moving time, and the corresponding opening time of the first dust removal device can be corrected using formula (1) and the actual speed.

[0120] In other embodiments, the detection position information may also represent the distance information between the current detection device and the previous detection device, for example, it may be the distance information between the current rolling mill and the previous rolling mill, or it may be the distance information between the current rolling mill and the previous hot metal detector; the detection time information represents the movement time of the steel to be processed from the previous detection device to the detection device; the actual speed of the steel to be processed can be calculated based on the distance information and the movement time, and the corresponding opening time of the first dust removal device can be corrected according to the actual speed.

[0121] In an embodiment of the present application, the actual speed of the steel to be processed is calculated by detecting position information and detection time information, so as to correct the opening time of the dust removal device in the subsequent rolling mill. This can improve the accuracy of the opening time of the dust removal device. Moreover, if the detection position information represents the distance information between the detection device and the flying shear, and the detection time information represents the movement time of the steel to be processed from the flying shear position to the detection device, this can more accurately determine the actual speed of the steel to be processed during this period, thereby making the corrected opening time more accurate.

[0122] Furthermore, in an embodiment of the present application, by acquiring a detection signal, and when the biting state of the target rolling mill is not detected at the start-up time, the start-up time corresponding to the first dust removal device is corrected according to the detection position information in the detection signal and the detection time information, so as to ensure the accuracy of the start-up time corresponding to the subsequent dust removal device, to ensure that the dust removal device can be accurately opened, thereby reducing impurities and pollutants being pressed into the steel, and ensuring the quality and performance of the steel.

[0123] In order to ensure the accuracy of the opening time, as another implementation of the present application, the present application also provides another implementation of the control method of the dust removal device, please refer to the following embodiments for details.

The dust removal device includes dust removal devices corresponding to multiple rolling mills for hot rolling of the steel to be processed. Figure 7 As shown, the control method of the dust removal device includes the following steps:

[0125] S710. Determine a target dust removal timing control strategy corresponding to the steel to be processed according to the rolling specifications of the steel to be processed and a preset corresponding relationship.

[0126] S720: Calculate the corresponding opening time of each dust removal device based on the target dust removal timing control strategy.

[0127] S730, controlling the corresponding dust removal device according to the opening time.

[0128] Exemplarily, steps S710-S7630 are consistent with steps S210-S230, and will not be described in detail here.

[0129] S740. When it is determined that the rolling mill has discarded its tail, turn off the dust removal device corresponding to the rolling mill.

[0130] For example, the tailing of the rolling mill can be determined by a pressure sensor installed in the rolling mill, wherein the tailing can be that all the steel to be processed passes through the rolling mill.

[0131] In the embodiment of the present application, when it is determined that the rolling mill has discarded its tail, shutting down the dust removal device corresponding to the rolling mill can avoid waste of resources and save costs.
