Description

Technical Field

[0001] This invention relates to the field of steel manufacturing technology, and in particular to a method, apparatus, equipment, and computer-readable storage medium for controlling the material distribution of an auxiliary door in a sintering machine. Background Technology

[0002] In the sintering process of the steel industry, sintering is always the core of the sintering process, and its production rhythm and efficiency directly affect various indicators such as output, quality, and energy consumption. Sintering is the central link in sintering production, including major processes such as material distribution, ignition, and sintering. Material distribution involves laying the base material and the mixture onto the sintering machine trolley. When using the base material process, a layer of small sintered ore with a particle size of 10-25mm and a thickness of 20-25mm is laid as the base material before the mixture is laid. This is to protect the grate bars, reduce dust removal load, extend the life of the blower rotor, and reduce or eliminate material adhesion to the grate bars. After laying the base material, the mixture is then distributed. During distribution, the particle size and chemical composition of the mixture must be evenly distributed along the longitudinal and transverse directions of the trolley, with a certain degree of looseness and a smooth surface.

[0003] Currently, a circular roller spreader is commonly used for material distribution. The mixture is drawn out from the bottom of the mixing buffer trough by the rotation of the circular rollers, and then evenly spread onto a moving trolley by a nine-roller spreader (e.g., Figure 1 and Figure 2 (As shown). The size of the discharge from the mixing buffer tank is generally determined by two factors. First, the rotational speed of the roller directly determines the discharge speed from the mixing buffer tank. The faster the rotational speed, the greater the discharge speed. Second, the size of the discharge opening of the mixing buffer tank also determines the discharge volume. When the rotational speed of the roller is constant, the larger the opening, the greater the discharge volume. The discharge opening of the mixing buffer tank is determined by the positions of the main door and auxiliary door installed on the tank. The distribution of the mixture at the sintering machine head is controlled by controlling the opening of the main and auxiliary doors.

[0004] Since the smoothness of the sintering mixture surface also affects the sintering effect and output, how to improve the smoothness of the sintering mixture surface by controlling the material distribution through the auxiliary door of the sintering machine during the material distribution process has become a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a method, device, equipment, and computer-readable storage medium for controlling the material distribution of the auxiliary door of a sintering machine. During use, the flatness of the sintering mixture surface can be adjusted, which is beneficial to improving the sintering effect and output.

[0006] To address the aforementioned technical problems, embodiments of the present invention provide a method for controlling the material distribution at the auxiliary door of a sintering machine, comprising:

[0022] For each of the auxiliary doors, the difference between the current thickness value and the adjusted target thickness value corresponding to the auxiliary door is calculated to obtain the thickness deviation corresponding to each of the auxiliary doors respectively;

[0023] If at least one of the thickness deviations is greater than a preset deviation, the cross-sectional shape of the mixture is determined to be inconsistent with the preset shape requirement; if none of the thickness deviations exceed the preset deviation, the cross-sectional shape of the mixture is determined to be consistent with the preset shape requirement.

[0024] Optionally, adjusting the target thickness value corresponding to each auxiliary door based on the average target thickness value and the average current thickness value to obtain an adjusted target thickness value includes:

[0025] For each of the auxiliary doors, the target thickness value corresponding to the auxiliary door is adjusted according to the first calculation formula based on the average target thickness value and the average current thickness value to obtain the adjusted target thickness value, wherein:

[0027] Optionally, when it is determined that the cross-sectional shape of the mixture does not meet the preset shape requirements, adjusting the opening of the corresponding auxiliary door to adjust the flatness of the mixture includes:

[0028] Based on the thickness deviation of each auxiliary door, the auxiliary door with a thickness deviation greater than a preset deviation is taken as the target auxiliary door.

[0029] According to the second calculation formula, the opening of the target auxiliary door is adjusted based on the target thickness value and the current thickness value corresponding to the target auxiliary door, wherein:

[0030] The second calculation formula is Vi=Vi0-Perc*(PVLi-SPLi+(AvgSP-AvgPV)), where Vi0 represents the current opening degree of the target auxiliary door, Perc represents the opening degree adjustment coefficient, PVLi represents the current thickness value corresponding to the i-th target auxiliary door, SPLi represents the target thickness value of the auxiliary door area corresponding to the i-th target auxiliary door, AvgSP represents the average target thickness value, and AvgPV represents the average current thickness value.

[0031] Optionally, adjusting the rotational speed of the roller to adjust the overall thickness of the mixture includes:

The method includes: determining whether the current flatness of the mixture in the material distribution area of ​​the sintering machine meets a preset flatness requirement; if not, adjusting the opening of the corresponding auxiliary door to adjust the flatness of the mixture; and determining whether the current overall thickness of the mixture meets a preset thickness requirement; if not, adjusting the rotational speed of the rollers to adjust the overall thickness of the mixture.

[0043] As can be seen, in this embodiment of the invention, during the material feeding process at the auxiliary gate of the sintering machine, the current flatness of the mixture in the feeding area of ​​the sintering machine is obtained, and it is determined whether the current flatness of the mixture meets the preset flatness requirement. If the preset flatness requirement is not met, the flatness of the mixture is adjusted by adjusting the opening of the corresponding auxiliary gate to make the surface of the mixture flatter. Furthermore, it is determined whether the current overall thickness of the mixture meets the preset thickness requirement. If the preset thickness requirement is not met, the overall thickness of the mixture is adjusted by adjusting the rotation speed of the roller.

[0051] This invention provides a method, device, equipment, and computer-readable storage medium for controlling the material distribution of an auxiliary door in a sintering machine. During use, the smoothness of the sintering mixture surface can be adjusted, which is beneficial to improving the sintering effect and output.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] Please refer to Figure 3 , Figure 3 This is a flowchart illustrating a method for controlling the material distribution at the auxiliary door of a sintering machine, provided in an embodiment of the present invention. The method includes:

[0054] S110: Determine whether the current flatness of the mixture in the feeding area of ​​the sintering machine meets the preset flatness requirements. If not, proceed to S120; if yes, proceed to S130.

[0055] It should be noted that, in this embodiment of the invention, when feeding material into the sintering machine, the current flatness of the mixture in the feeding area of ​​the sintering machine can be obtained, and it can be determined whether the current flatness meets the preset flatness requirement. If the preset flatness requirement is met, proceed to S130; if the preset flatness requirement is not met, proceed to S120.

[0056] S120: Adjust the opening degree of the corresponding auxiliary gate to adjust the flatness of the mixture;

[0057] Specifically, in the embodiments of the present invention, when it is determined that the current flatness does not meet the preset flatness requirements, it means that the current flatness of the mixture is not good and does not meet the flatness requirements. At this time, the flatness of the mixture can be further adjusted by adjusting the opening of the corresponding auxiliary door. After the flatness adjustment is completed, S130 can be further executed to determine whether the current overall thickness of the mixture meets the preset thickness requirements.

[0058] S130: Determine whether the current overall thickness of the mixture meets the preset thickness requirement. If not, proceed to S140.

[0059] Specifically, after adjusting the opening of the corresponding auxiliary gate to adjust the flatness of the mixture surface, it is necessary to further determine whether the current overall thickness of the mixture meets the preset thickness requirement. If it does not meet the preset thickness requirement, proceed to S140. Additionally, if it is determined that the current flatness meets the preset flatness requirement, it indicates that the flatness of the mixture is good. At this point, it is also necessary to further determine whether the current overall thickness of the mixture meets the preset thickness requirement. If it does not meet the requirement, proceed to S140.

[0060] Of course, if it is determined that the current overall thickness of the mixture meets the preset thickness requirement, then as the fabric is laid, the process proceeds to the next time step, and the method provided by the embodiments of the present invention is executed in the next time step.

[0061] S140: Adjust the rotational speed of the rollers to adjust the overall thickness of the mixture.

[0062] Specifically, if the current overall thickness does not meet the preset thickness requirement, the overall thickness of the mixture is further adjusted by regulating the rotation speed of the rollers so that the overall thickness of the mixture reaches the preset thickness requirement. Of course, after adjusting the roller speed, the process can proceed to the next time step and execute the method provided in this embodiment of the invention in the next time step.

[0063] It is understood that, in order to reduce the frequent operation of the auxiliary door, stabilize the thickness of the sintering machine mixture, improve the flatness of the mixture surface, and improve the overall effect of sintering and material distribution, the functions of the control equipment can be reassigned based on the original control equipment. The flatness of the mixture on the sintering machine can be adjusted by adjusting the opening of the auxiliary door, and the overall flatness of the mixture can be adjusted by adjusting the rotation speed of the roller.

[0064] As can be seen, in this embodiment of the invention, during the material feeding process at the auxiliary gate of the sintering machine, the current flatness of the mixture in the feeding area of ​​the sintering machine is obtained, and it is determined whether the current flatness of the mixture meets the preset flatness requirement. If the preset flatness requirement is not met, the flatness of the mixture is adjusted by adjusting the opening of the corresponding auxiliary gate to make the surface of the mixture flatter. Furthermore, it is determined whether the current overall thickness of the mixture meets the preset thickness requirement. If the preset thickness requirement is not met, the overall thickness of the mixture is adjusted by adjusting the rotation speed of the roller. This achieves the adjustment of the thickness and flatness of the mixture, promotes combustion and ignition, and is beneficial to improving the sintering effect and output.

[0065] Furthermore, the process in S110 above, which determines whether the current flatness of the mixture in the material distribution area of ​​the sintering machine meets the preset flatness requirement, may specifically include:

[0066] Obtain the current cross-sectional shape information of the mixture in the material feeding area of ​​the sintering machine;

[0067] Based on the cross-sectional shape information of the mixture, it is determined whether the cross-sectional shape of the mixture meets the preset shape requirements. If the cross-sectional shape of the mixture meets the preset shape requirements, it is determined that the current flatness meets the preset flatness requirements. If the cross-sectional shape of the mixture does not meet the preset shape requirements, it is determined that the current flatness does not meet the preset flatness requirements. It should be noted that the sintering machine is equipped with multiple auxiliary doors, and the entire area corresponding to all auxiliary doors can be used as the feeding area. In order to detect the flatness of the mixture in the feeding area, the current cross-sectional shape information of the mixture in the feeding area of ​​the sintering machine can be obtained during the feeding process.

[0068] Specifically, in practical applications, the shape requirements of the mixture cross-section can be preset, that is, the standard shape of the mixture cross-section can be predetermined. Then, based on the preset shape requirements, the obtained current mixture cross-section shape information is judged to determine whether the current mixture cross-section shape information meets the preset shape requirements. If the preset shape requirements are met, it means that the current flatness of the mixture meets the preset flatness requirements. At this time, it can enter S130 to further judge whether the current thickness value of the mixture meets the preset thickness value requirements. If the preset shape requirements are not met, it means that the current flatness of the mixture does not meet the preset flatness requirements. Then it is necessary to enter S120 to adjust the flatness of the mixture by adjusting the opening of the corresponding auxiliary door.

[0069] Furthermore, the process of obtaining the current cross-sectional shape information of the mixture in the material distribution area of ​​the sintering machine can specifically include:

[0070] Obtain the current thickness value of the mixture in the auxiliary gate area corresponding to each auxiliary gate;

[0071] The current cross-sectional shape information of the mixture in the fabric area is determined based on each current thickness value.

[0072] Understandably, in practical applications, each auxiliary gate corresponds to a specific auxiliary gate area on the sintering machine, and each auxiliary gate corresponds to a layer thickness gauge used to obtain the thickness value of the mixture in the area corresponding to that auxiliary gate. When obtaining the current cross-sectional shape information of the mixture in the material distribution area on the sintering machine, specifically, the current thickness value of the mixture in each auxiliary gate area can be obtained through the layer thickness gauge corresponding to each auxiliary gate, and the current cross-sectional shape information of the mixture in the material distribution area can be further determined based on each current thickness value. That is, each area corresponds to a current thickness value, and the cross-sectional shape of the mixture formed in each area can be determined based on each current thickness value.

[0073] Furthermore, the process of determining whether the cross-sectional shape of the mixture meets the preset shape requirements based on the cross-sectional shape information of the mixture can specifically include:

[0074] Obtain the target thickness value of the mixture in the area corresponding to each auxiliary gate;

[0075] Based on the preset deviation and the current thickness value and target thickness value corresponding to each auxiliary gate, it is determined whether the cross-sectional shape of the mixture meets the preset shape requirements. The preset shape requirements are determined based on each target thickness value.

[0076] It should be noted that in practical applications, a target thickness value can be set for each auxiliary door in advance, and a preset deviation can also be set. Therefore, after obtaining the current thickness value corresponding to each auxiliary door, the cross-sectional shape of the mixture can be further determined based on the target thickness value, the current thickness value, and the preset deviation corresponding to each auxiliary door. The preset shape requirement can be determined based on the target thickness value corresponding to each auxiliary door.

[0077] Furthermore, the process of determining whether the cross-sectional shape of the mixture meets the preset shape requirements based on the preset deviation and the current thickness value and target thickness value corresponding to each auxiliary gate can specifically include:

[0078] The average target thickness value is calculated based on the target thickness value corresponding to each auxiliary door.

[0079] The average current thickness value is calculated based on the current thickness value corresponding to each auxiliary door.

[0080] For each auxiliary door, the target thickness value corresponding to the auxiliary door is adjusted based on the average target thickness value and the average current thickness value to obtain the adjusted target thickness value;

[0081] For each auxiliary door, calculate the difference between the current thickness value and the adjusted target thickness value corresponding to the auxiliary door to obtain the thickness deviation corresponding to each auxiliary door.

[0082] If at least one of the thickness deviations is greater than the preset deviation, the cross-sectional shape of the mixture is determined to be inconsistent with the preset shape requirements. If none of the thickness deviations exceed the preset deviations, the cross-sectional shape of the mixture is determined to be consistent with the preset shape requirements.

[0083] It should be noted that in practical applications, the sintering machine has multiple auxiliary doors (generally 5 to 7 sets of auxiliary doors are set according to the width of the sintering trolley), and multiple auxiliary doors jointly control the lateral flatness of the mixture surface. Each auxiliary door corresponds to a layer thickness gauge. In order to further ensure that the flatness of the mixture after material distribution is consistent with the set target shape, in the implementation of this invention, for the target thickness value of the auxiliary door area of ​​each auxiliary door, the average target thickness value can be calculated based on each target thickness value, and the current thickness value corresponding to each auxiliary door can be obtained at the current moment. Then, the average current thickness value can be calculated based on each current thickness value.

[0084] In this embodiment of the invention, five auxiliary doors and five layer thickness gauges are arranged at equal intervals along the transverse direction of the sintering trolley as an example. Each auxiliary door and its corresponding layer thickness gauge are directly opposite each other along the longitudinal direction of the sintering machine. Figure 2 As shown. The target layer thickness values ​​for each auxiliary door area are SPL1, SPL2, SPL3, SPL4, and SPL5, which correspond to the control targets of layer thickness gauges #1, #2, #3, #4, and #5. In actual production applications, the target layer thickness values ​​after the three middle layers are usually consistent, while the two target layer thickness values ​​at both ends are appropriately larger, as shown below. Figure 4 As shown. At the current moment, the current thickness values ​​of the mixture in the auxiliary gate area corresponding to each auxiliary gate are PVL1, PVL2, PVL3, PVL4, and PVL5, respectively. The opening degrees of the five auxiliary gates are represented by V1, V2, V3, V4, and V5, respectively.

[0085] Therefore, the target average thickness value is AvgSP = (SPL1 + SPL2 + SPL3 + SPL4 + SPL5) / 5, and the current average thickness value is AvgPV = (PVL1 + PVL2 + PVL3 + PVL4 + PVL5) / 5.

[0086] In this embodiment of the invention, to further ensure that the cross-sectional shape of the mixture after fabrication is consistent with the preset shape, the target thickness value corresponding to each auxiliary gate can be adjusted using the average target thickness value and the current average thickness value to eliminate the average difference between the average value of the set material level and the detected thickness value, thereby obtaining the adjusted target thickness value corresponding to each auxiliary gate. Then, for each auxiliary gate, the difference between the current thickness value corresponding to the auxiliary gate and the adjusted target thickness value is calculated, and this difference is used as the thickness deviation corresponding to the auxiliary gate, thereby obtaining the thickness deviation corresponding to each auxiliary gate. Furthermore, it is determined whether there is at least one thickness deviation greater than the preset deviation among the various thickness deviations. If there is at least one thickness deviation greater than the preset deviation, it is determined that the cross-sectional shape of the mixture does not meet the preset shape requirements. If none of the thickness deviations exceed the preset deviation, it is determined that the cross-sectional shape of the mixture meets the preset shape requirements.

[0087] Furthermore, the process of adjusting the target thickness value corresponding to each auxiliary door based on the average target thickness value and the average current thickness value to obtain the adjusted target thickness value can specifically include:

[0088] For each auxiliary door, according to the first calculation formula, the target thickness value corresponding to the auxiliary door is adjusted based on the average target thickness value and the average current thickness value to obtain the adjusted target thickness value, where:

[0089] The first calculation formula is spLi=SPLi-(AvgSP-AvgPV), where spLi represents the adjusted target thickness value corresponding to the i-th auxiliary gate, SPLi represents the target thickness value corresponding to the i-th auxiliary gate, AvgSP represents the average target thickness value, and AvgPV represents the average current thickness value.

[0090] Understandably, in practical applications, the target thickness value can be adjusted based on the first calculation formula spLi=SPLi-(AvgSP-AvgPV) to obtain the adjusted target thickness value. For example, the adjusted target thickness value for auxiliary door 1 is spL1=SPL1-(AvgSP-AvgPV), and the adjusted target thickness value for auxiliary door 2 is spL2=SPL2-(AvgSP-AvgPV).

[0091] Furthermore, when it is determined that the cross-sectional shape of the mixture does not meet the preset shape requirements, the opening of the corresponding auxiliary gate is adjusted to adjust the flatness of the mixture. This process may specifically include:

[0092] Based on the thickness deviation of each auxiliary door, the auxiliary door with a thickness deviation greater than the preset deviation is taken as the target auxiliary door;

[0093] According to the second calculation formula, the opening of the target auxiliary door is adjusted based on the target thickness value and the current thickness value corresponding to the target auxiliary door, wherein:

[0094] The second calculation formula is Vi=Vi0-Perc*(PVLi-SPLi+(AvgSP-AvgPV)), where Vi0 represents the current opening degree of the target auxiliary door, Perc represents the opening degree adjustment coefficient, PVLi represents the current thickness value corresponding to the i-th target auxiliary door, SPLi represents the target thickness value of the auxiliary door area corresponding to the i-th target auxiliary door, AvgSP represents the average target thickness value, and AvgPV represents the average current thickness value.

[0095] Specifically, in this embodiment of the invention, the target auxiliary gate with a thickness deviation greater than the preset deviation can be determined first based on the thickness deviation of each auxiliary gate and the preset deviation. This target auxiliary gate is the auxiliary gate whose opening needs to be adjusted. Then, the opening of the target auxiliary gate is adjusted according to the second calculation formula Vi=Vi0-Perc*(PVLi-SPLi+(AvgSP-AvgPV)) to improve the adjustment accuracy and make the adjusted mixture smoother. The target auxiliary gate can be one or multiple, depending on the actual situation. This embodiment of the invention does not impose any special limitations on this, as long as the purpose of the invention is achieved.

[0096] Furthermore, the process of adjusting the rotational speed of the roller in S140 above to adjust the overall thickness of the mixture may specifically include:

[0097] The rotational speed of the roller is adjusted based on the average target thickness value, the average current thickness value, and the current rotational speed of the roller to adjust the overall thickness of the mixture.

[0098] It should also be noted that, in the embodiments of the present invention, when determining whether the current overall thickness of the mixture meets the preset thickness requirement, it can be determined whether the average current thickness value meets the requirement of the translation target thickness value. If it does not meet the requirement, the overall thickness of the sintering machine mixing layer (i.e., the longitudinal flatness of the sintering machine) can be controlled by controlling the rotation speed of the roller. Furthermore, during the material distribution process, the rotation speed of the roller is adjusted by PID based on the target average thickness value, the current target thickness value, and the current rotation speed of the roller, so as to accurately control the overall thickness of the sintering machine mixing layer.

[0101] The first adjustment module 12 is used to adjust the opening degree of the corresponding auxiliary door in order to adjust the flatness of the mixture;

[0102] The second judgment module 13 is used to determine whether the current overall thickness of the mixture meets the preset thickness requirement. If not, the second adjustment module 14 is triggered.

[0103] The second adjustment module 14 is used to adjust the rotation speed of the roller to adjust the overall thickness of the mixture.
