Abstract
Description
Technical Field
[0001] This application relates to the field of iron and steel metallurgy technology, and in particular to a method, apparatus, electronic device and storage medium for determining the surface cleaning of steel strip. Background Technology
[0002] Currently, in the pretreatment process before the cold rolling process in the metallurgical industry, rolling oil and emulsion are used. Inevitably, some metal particles, decomposed carbon, hydrogen compounds, incidental chemical reaction products, leaked machine oil, and dust generated during the rolling process remain on the surface of the strip steel. These impurities mix together to form highly viscous oil stains that adhere firmly to the strip steel. If the strip steel is not cleaned properly, the oil stains will be carried into the annealing furnace, which will damage the protective atmosphere composition inside the furnace and affect the decarburization efficiency.
[0003] However, traditional strip steel cannot be completely cleaned after alkaline spraying and brushing because the surface of the strip steel has a certain roughness after rolling. Many oil and dirt particles are attached to the pits on the surface of the strip steel, which are very difficult to remove completely. This can easily lead to poor coating quality on the surface of the strip steel, causing defects such as scratches on the surface of the strip steel, and in severe cases, it can cause nodules on the furnace bottom rolls. Summary of the Invention
[0004] This application provides a method, apparatus, electronic device, and storage medium for determining the surface cleaning of strip steel. The embodiments provided by this application solve the technical problem in the prior art where many oil and dirt particles adhere to the pits on the surface of strip steel, making them difficult to thoroughly remove and clean. This can easily lead to defects such as poor coating quality, scratches, and even nodule formation on the furnace bottom rolls. The embodiments provided by this application achieve the electrolysis of strip steel and encapsulate a large amount of gas on the surface of the strip steel, forcing the oil and dirt in the pits to leave the strip steel. This effectively reduces the problems of incomplete cleaning, difficulty in thorough removal, and lack of complete cleaning of the strip steel surface, thereby reducing the probability of scratches on the strip steel surface and improving the cleaning quality of the strip steel.
[0005] In a first aspect, this application provides a method for determining the surface cleanliness of a strip steel, using an external strip steel surface cleaning device. The method includes: Based on the preset electrolysis parameters of the strip steel during the electrolytic cleaning stage, the surface of the strip steel is electrolytically cleaned to determine the target polarity of the strip steel surface; Based on the target polarity and the preset electrolytic cleaning chemical formula, the amount of gas released during the electrolytic reaction on the surface of the strip is determined. Based on the gas release amount and the preset gas release amount threshold of the strip surface under the oil stain removal state, the cleaning quality parameters of the strip surface are determined.
[0006] In one feasible implementation, the preset electrolysis parameters for the strip steel during the electrolytic cleaning stage are determined by the following method: The actual current output value, actual voltage output value, and actual electrolysis time of the external strip steel surface cleaning device are obtained, wherein the external strip steel surface cleaning device is a device for electrolytically cleaning the strip steel.

[0008] In one feasible implementation, determining the oil stain removal status at the depressions on the strip surface based on the gas release amount and a preset gas release amount threshold for the strip surface under oil stain removal conditions includes: If the amount of gas released is less than the preset gas release threshold of the strip surface under the state of oil stain removal, the state of oil stain removal at the depression on the strip surface is determined to be the state of incomplete oil stain removal. If the gas release amount is greater than or equal to the preset gas release amount threshold of the strip surface under the oil stain peeling state, the oil stain peeling state at the depression of the strip surface is determined to be the oil stain completely peeled state.
[0009] In one feasible implementation, determining the quality parameters of the strip steel surface cleaning based on the oil stain peeling state and a preset cleaning quality mapping rule includes: If the oil stains in the depressions on the surface of the strip are completely removed, the quality parameter of the strip surface cleaning is determined to be 100%. If the oil stains in the depressions on the surface of the strip are not completely removed, the quality parameter ratio of the strip surface cleaning is determined based on the preset cleaning quality mapping rule.

In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element. The term "two or more" includes two or more cases.
[0020] First, the applicable application scenarios of this application will be introduced. The embodiments provided in this application are applicable to the field of iron and steel metallurgy technology.
[0021] Currently, traditional strip steel cannot be completely cleaned after alkaline spraying and brushing because the surface of the strip steel has a certain roughness after rolling. Many oil and dirt particles are attached to the pits on the surface of the strip steel, which are very difficult to remove completely. This can easily affect the coating quality of the strip steel surface, causing defects such as scratches on the strip steel surface, and in severe cases, it can cause nodules on the furnace bottom rolls.
[0022] Based on this, the embodiments of this application provide a method, apparatus, electronic device, and storage medium for determining the surface cleaning of strip steel. The embodiments provided by this application solve the technical problem in the prior art where many oil and dirt particles adhere to the pits on the surface of strip steel, making them difficult to thoroughly remove and clean completely. This can easily lead to defects such as poor coating quality and scratches on the surface of the strip steel, and in severe cases, it can cause nodules on the furnace bottom rolls. The embodiments provided by this application realize the electrolysis of strip steel and wrap a large amount of gas around the surface of the strip steel to force the oil and dirt in the pits on the surface of the strip steel to leave the strip steel, effectively reducing the problem of incomplete cleaning and difficulty in thoroughly removing and cleaning the surface of the strip steel, thereby reducing the probability of scratches on the surface of the strip steel and improving the cleaning quality of the strip steel.
[0023] Figure 1A flowchart illustrating a method for determining the surface cleaning of a steel strip provided in this application embodiment is shown below. Figure 1 As shown, the method for determining the surface cleaning of strip steel includes the following steps: S101. Based on the preset electrolysis parameters of the strip steel during the electrolytic cleaning stage, the surface of the strip steel is electrolytically cleaned to determine the target polarity of the strip steel surface.
[0024] In this step, the embodiments provided in this application require four stages for cleaning the strip steel surface when it is determined that cleaning is necessary: alkaline spraying, alkaline brushing, water brushing, and water rinsing. However, after alkaline spraying and alkaline brushing, the embodiments provided in this application require electrolytic cleaning of contaminants hidden in the pits of the strip steel. At this time, it is necessary to pre-determine the preset electrolytic parameters of the strip steel in the electrolytic cleaning stage, and then perform electrolytic cleaning on the surface of the strip steel based on the above preset electrolytic parameters to determine the target polarity of the strip steel surface.
[0025] It should be noted that, in the embodiments provided in this application, when electrolytically cleaning the surface of the strip steel, motors need to be installed on both sides of the strip steel first, and then direct current is applied. When the electrode is polarized, the strip steel will be charged with a charge opposite to that of the electrode due to induction. If the electrode is negative, the strip steel is positive; conversely, if the electrode is positive, the strip steel is negative. However, regardless of whether the strip steel is positive or negative, a large amount of gas will be released.
[0026] Understandably, alkaline spraying is used to characterize a chemical degreasing reaction, which is a chemical method that uses the saponification, emulsification, and dispersing effects of degreasing agents to remove grease from the surface of the steel plate. Alkaline brushing is used to characterize a physical cleaning process, specifically the process of removing residual oil and other contaminants floating on the surface of the strip steel after alkaline spraying by mechanical brushing. Water brushing further removes floating oil and alkaline solution left on the surface of the strip steel by brushing with brush rollers and rinsing with hot water. Water rinsing uses rinsing water to rinse the strip steel, thereby removing all residual contaminants and cleaning agents.
[0027] Among them, saponification is used to characterize the process in which fats (esters) react with alkali to produce glycerol and soap (i.e., fatty acid salts).
[0028] For example, the embodiments provided in this application determine the preset electrolysis parameters of the strip steel during the electrolytic cleaning stage in the following manner: The process involves acquiring the actual current output, actual voltage output, and actual electrolysis time of an external strip steel surface cleaning device (which performs electrolytic cleaning on the strip steel). Based on the target steel type corresponding to the strip steel, target current threshold, target voltage threshold, and target time threshold matching the target steel type are determined from a pre-set electrolysis parameter database. The actual current output is compared with the target current threshold, the actual voltage output is compared with the target voltage threshold, and the actual electrolysis time is compared with the target time threshold to determine the comparison results. Compliance verification is performed based on the comparison results to determine the preset electrolysis parameters for the strip steel during the electrolytic cleaning stage.
[0029] It is understood that the embodiments provided in this application verify and determine the preset electrolysis parameters of different types of strip steel in the electrolytic cleaning stage by using different target steel types, thereby meeting the needs of different types of strip steel.
[0030] It should be noted that the different target steel types in the embodiments provided in this application can be customized and used according to different application scenarios and usage conditions.
[0031] S102. Based on the target polarity and the preset electrolytic cleaning chemical formula, determine the amount of gas released from the strip surface during the electrolytic reaction.
[0032] In this step, after determining the target polarity of the strip surface, the embodiments provided in this application begin to determine the amount of gas released when the strip surface undergoes an electrolytic reaction by using a preset electrolytic cleaning chemical formula, i.e., the formula for electrolyzing water. The gas generated during the electrolytic reaction in the embodiments provided in this application can be hydrogen (H2) and oxygen (O2), etc.
[0033] As can be understood, the electrolytic cleaning process of the strip surface in the embodiments provided in this application is actually a water electrolysis process, which involves the decomposition of water in a solution. The specific electrolytic chemical formula is as follows:
[0034] The chemical formula for the hydrogen gas produced during the reaction at the cathode is: ; The chemical formula for the oxygen released during the reaction at the anode is: ; Here, as a large amount of gas is generated on the surface of the strip, the oil stains in the pits on the strip surface are removed from the strip, thereby reducing the problem of incomplete cleaning of the strip surface.
[0035] S103. Based on the gas release rate and the preset gas release rate threshold of the strip surface under the oil stain removal state, determine the cleaning quality parameters of the strip surface.
[0036] In this step, after completing water electrolysis and generating gas release, the embodiments provided in this application determine the cleaning quality parameters of the strip surface by comparing the gas release amount with a preset gas release amount threshold of the strip surface under oil stain removal state.
[0037] For example, the oil stain removal status at the depressions on the strip surface is determined based on the gas release amount and a preset gas release amount threshold on the strip surface under oil stain removal status; the cleaning quality of the strip surface is determined based on the oil stain removal status and a preset cleaning quality mapping rule.
[0038] In the above, if the gas release amount is less than the preset gas release amount threshold of the strip surface under the oil stain peeling state, the oil stain peeling state of the depression on the strip surface is determined to be the state of incomplete oil stain peeling; if the gas release amount is greater than or equal to the preset gas release amount threshold of the strip surface under the oil stain peeling state, the oil stain peeling state of the depression on the strip surface is determined to be the state of complete oil stain peeling.
[0039] For example, if the oil stains in the depressions on the strip surface are completely removed, the quality parameter of the strip surface cleaning is determined to be 100%; if the oil stains in the depressions on the strip surface are not completely removed, the quality parameter ratio of the strip surface cleaning is determined based on the preset cleaning quality mapping rules.
[0040] In the above, this application determines the state of oil stain removal at the depression on the strip surface as an incomplete oil stain removal state, determines the residual coverage ratio of the depression area on the strip surface, and determines the corresponding strip surface cleaning quality parameter ratio from the preset cleaning quality mapping rules based on the above coverage ratio.
[0041] It should be noted that when it is determined that the oil stains have not been completely removed, the proportion of quality parameters is adjusted based on the multi-level cleaning synergy strategy. Then, the alkali concentration of the strip in the alkali spray washing stage, the brush roller pressure of the strip in the alkali brush washing stage, and the water flow rate of the strip in the water rinsing stage are obtained. Based on the above parameters and the defect location distribution of the incomplete oil stain removal, the parameter values of at least one of the above three stages are dynamically increased according to the preset weight coefficient.
[0042] Compared with the prior art, the method for determining the surface cleaning of strip steel provided in this application provides an embodiment that electrolyzes the surface of the strip steel based on preset electrolysis parameters during the electrolytic cleaning stage, determines the target polarity of the strip steel surface, and then determines the amount of gas released during the electrolytic reaction based on the target polarity and the preset electrolytic cleaning chemical formula. Based on the amount of gas released and the preset gas release threshold of the strip steel surface under the oil stain peeling state, the cleaning quality parameters of the strip steel surface are determined. The embodiment provided in this application realizes the electrolysis of strip steel and forces the oil stains in the pits of the strip steel surface to leave the strip steel by wrapping a large amount of gas on the strip steel surface. This effectively reduces the problems of incomplete cleaning, difficulty in thorough removal and complete cleaning of the strip steel surface, thereby reducing the probability of scratches on the strip steel surface and improving the cleaning quality of the strip steel.
[0043] Figure 2 This application provides an external connection circuit for a steel strip surface cleaning device according to an embodiment of the present application. For example... Figure 2 As shown, the strip surface cleaning device 300 is connected to the electrode plate in the external electrolytic cell via wires, and strip steel is placed in both the strip surface cleaning device 300 and the external electrolytic cell.
[0044] In the embodiments provided in this application, the positive electrode of the electrode plate is connected to the strip steel surface cleaning device 300 via 8 cables, and the negative electrode of the electrode plate is connected to the strip steel surface cleaning device 300 via 4 cables.
[0045] It should be noted that in the embodiments provided in this application, electrode plates are installed on both sides of the strip and a direct current is applied. When the electrode plates are polarized, the strip will be charged with a polarity opposite to that of the electrode plates due to induction. At this time, if the electrode plates are negative, the strip will be positive; conversely, if the electrode plates are positive, the strip will be negative. However, regardless of whether the strip is positive or negative, a large amount of gas will be released.
[0046] The electrode plate in the embodiments provided in this application can generate positive and negative electrodes, causing the electrolyte to generate positive and negative ions. The positive and negative ions react chemically to generate gas, which cleans the oil stains on the surface of the strip steel.
[0047] Figure 3 This is a circuit diagram of a strip steel surface cleaning device 300 provided for an embodiment of this application. Figure 3As shown, the strip surface cleaning device 300 includes a main circuit breaker 1, a main transformer 2, a thyristor rectifier 3, a sensor assembly 4, a power supply 6, and a main controller 5. The power supply terminal of the power supply 6 is electrically connected to one end of the main circuit breaker 1, and the other end of the main circuit breaker 1 is electrically connected to the AC input terminal of the thyristor rectifier 3. The DC output terminal of the thyristor rectifier 3 is electrically connected to the input terminal of the sensor assembly 4, and the output terminal of the sensor assembly 4 is electrically connected to the input terminal of the main controller 5. The power supply terminal of the main controller 5 is electrically connected to one end of the main circuit breaker 1, and the output terminal of the main controller 5 is electrically connected to the signal terminal of the thyristor rectifier 3.
[0048] It should be noted that the sensor component 4 in the embodiments provided in this application includes a voltage sensor and a current sensor, and the thyristor rectifier 3 in the embodiments provided in this application adopts anti-parallel thyristor rectification to realize the positive and negative commutation function.
[0049] For example, the strip surface cleaning device 300 also includes a water circulation component 7, which is connected to the main transformer 2, the thyristor rectifier 3 and the sensor component 4, and the water circulation component 7 is composed of a heat exchanger, a cooler and a water supply tank.
[0050] In the embodiments provided in this application, the alternating current is converted into direct current through the thyristor rectifier 3, and the anti-parallel thyristors in the thyristor rectifier 3 can realize the positive and negative commutation function. In the embodiments provided in this application, the voltage sensor and the current sensor feed back the signal to the main controller 5. The main controller 5 controls the current output by adjusting the on and off of the thyristors, and the water circulation component 7 ensures the heat dissipation of electrical components. Since the electrical equipment generates a lot of heat, the cooling effect of the water circulation component 7 is more prominent.
[0051] In the above-mentioned embodiments, the main transformer 2 and the thyristor rectifier 3 are the main functional electrical components of the strip steel surface cleaning device 300.
[0052] Figure 4 This is a structural block diagram of a strip steel surface cleaning determination device provided in an embodiment of this application. Figure 4 As shown, the fault identification model determination device 400 includes: The first determining module 410 is used to perform electrolytic cleaning on the surface of the strip steel based on the preset electrolytic parameters of the strip steel in the electrolytic cleaning stage, and to determine the target polarity of the strip steel surface.
[0053] The second determining module 420 is used to determine the amount of gas released from the surface of the strip steel during the electrolytic reaction based on the target polarity and the preset electrolytic cleaning chemical formula.
[0054] The third determining module 430 is used to determine the cleaning quality parameters of the strip surface based on the gas release amount and a preset gas release amount threshold of the strip surface under the oil stain peeling state.
[0055] For example, the preset electrolysis parameters for the strip steel during the electrolytic cleaning stage are determined in the following manner: The actual current output value, actual voltage output value, and actual electrolysis time of the external strip steel surface cleaning device are obtained. The external strip steel surface cleaning device is a device for electrolytic cleaning of strip steel.
[0056] Based on the target steel type corresponding to the strip, the target current threshold, target voltage threshold, and target duration threshold that match the target steel type are determined from the electrolysis parameter preset database.
[0057] The actual current output value is compared with the target current threshold, the actual voltage output value is compared with the target voltage threshold, and the actual electrolysis time is compared with the target time threshold to determine the comparison results.
[0058] Compliance verification was conducted based on the comparison results to determine the preset electrolysis parameters for the strip steel during the electrolytic cleaning stage.
[0059] For example, the third determining module 430 is specifically used for: Based on the gas release amount and the preset gas release amount threshold of the strip surface under oil stain peeling state, the oil stain peeling state of the depressions on the strip surface is determined.
[0060] The quality of the strip steel surface cleaning is determined based on the mapping rules between the oil stain peeling state and the preset cleaning quality.
[0061] For example, based on the gas release amount and a preset gas release amount threshold on the strip surface under oil stain peeling conditions, the oil stain peeling state at the depressions on the strip surface is determined, including: If the gas release is less than the preset gas release threshold for the strip surface under oil stain removal conditions, the oil stain removal state at the depression on the strip surface is determined to be an incomplete oil stain removal state.
[0062] If the gas release amount is greater than or equal to the preset gas release amount threshold of the strip surface under the oil stain peeling state, the oil stain peeling state at the depression on the strip surface is determined to be the oil stain completely peeled state.
[0063] For example, based on the oil stain peeling state and a preset cleaning quality mapping rule, the quality parameters of the strip steel surface cleaning are determined, including: If the oil stains in the depressions on the strip surface are completely removed, the quality parameter for cleaning the strip surface is set to 100%.
[0064] If the oil stains in the depressions on the strip surface are incompletely removed, the proportion of quality parameters for cleaning the strip surface is determined based on the preset cleaning quality mapping rules.
[0065] The strip surface cleaning determination device 400 provided in this application embodiment, compared with the prior art, performs electrolytic cleaning on the surface of the strip based on preset electrolytic parameters during the electrolytic cleaning stage, determines the target polarity of the strip surface, and then determines the amount of gas released during the electrolytic reaction based on the target polarity and the preset electrolytic cleaning chemical formula. Based on the gas release amount and the preset gas release amount threshold of the strip surface under the oil stain peeling state, the cleaning quality parameters of the strip surface are determined. The embodiment provided in this application realizes the electrolysis of the strip and forces the oil stains in the pits of the strip surface to leave the strip by wrapping a large amount of gas around the strip surface, effectively reducing the problems of incomplete cleaning, difficulty in thorough removal and complete cleaning of the strip surface, thereby reducing the probability of scratches on the strip surface and improving the cleaning quality of the strip.
