Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the feature.

[0056] Figure 1 shows a schematic diagram of a strip steel continuous coating unit, Figure 1 In the figure, the arrows correspond to the running direction of the strip steel, 1 is the spray beam, 2 is the coating machine, 3 is the coating roller, 4 is the drying furnace, 5 is the liquid collecting tank, 6 is the liquid level gauge, 7 is the coating liquid circulation tank, and 8 is the circulation pump. For a better understanding of the embodiments of the present application, see Figure 1 , the strip steel continuous coating unit is described:

[0057] The strip enters the coating machine, and the circulation pump transports the coating liquid in the coating liquid circulation tank to the spray beam. The spray beam allows the coating liquid to hit the upper and lower surfaces of the strip. The coating roller evenly applies the coating liquid to the upper and lower surfaces of the strip. The excess coating liquid falls into the liquid collecting tank and then flows back to the coating liquid circulation tank through the pipeline. The strip enters the drying furnace from the coating machine, and the drying furnace dries the strip. The coating liquid on the upper and lower surfaces of the strip becomes a coating.

[0058] Figure 2 A flow chart showing a method for determining a coating amount in an embodiment of the present application is shown, see Figure 2 , provides a coating amount determination method, applied to strip steel, including at least S1 to S5,:

[0059] In step S1, the inner bottom area of ​​the coating liquid circulation tank, the coating liquid density, the strip speed, the strip width, the target time period, and the drying ratio coefficient corresponding to the coating liquid after being dried in the drying furnace are obtained. The coating liquid circulation tank is used to store the coating liquid. The inner bottom area of ​​the coating liquid circulation tank refers to the bottom area of ​​the inner wall of the coating liquid circulation tank. The product of the inner bottom area and the height of the inner wall of the coating liquid circulation tank is the volume of the inner wall of the coating liquid circulation tank, that is, the volume of the coating liquid that can be stored in the coating liquid circulation tank. The coating liquid density refers to the density of the coating liquid. The strip speed refers to the speed of the strip passing through the coating machine. The strip width refers to the width of the strip perpendicular to the running direction of the strip. The target time period refers to the corresponding time period for determining the coating coating amount. The drying ratio coefficient refers to the ratio of the first mass of the coating liquid after being dried in the drying furnace to the second mass of the coating liquid before being dried in the drying furnace.

[0060] In some embodiments, obtaining the strip speed includes: obtaining the strip speed according to a rotary encoder of a tension roller, wherein the coating machine is located between the tension roller and a drying furnace, that is, the tension roller is located in front of the coating machine, and the drying furnace is located behind the coating machine.

[0061] In some embodiments, when obtaining the inner bottom area, it can be obtained through the parameters of the coating liquid circulation tank, or it can be obtained by measurement; when obtaining the coating liquid density, it can be obtained through the coating liquid parameters, or it can be obtained by measurement, such as by measuring the mass of the coating liquid per unit volume to measure the density of the coating liquid; when obtaining the strip width, it can be obtained through the strip parameters, or it can be obtained by measurement, such as by measuring with a tape measure; when obtaining the target time period, it can be set according to experience, or it can be set according to the strip speed, for example, the faster the strip speed, the shorter the target time period, so that the strip coating amount can be determined in time, or the target time period can be set to a fixed value.

[0062] In step S2, the amount of change in the liquid level of the coating liquid circulation tank within the target time period is determined. The target time period refers to the time period between the first time and the second time, wherein the first time is before the second time, and the amount of change in the liquid level refers to the amount of change in the liquid level of the coating liquid circulation tank corresponding to the second time relative to the liquid level of the coating liquid circulation tank corresponding to the first time, for example, if the liquid level of the coating liquid circulation tank corresponding to the second time is 60 cm and the liquid level of the coating liquid circulation tank corresponding to the first time is 62 cm, then the amount of change in the liquid level is 2 cm.

[0063] In some embodiments, the determination of the liquid level change of the coating liquid circulation tank within the target time period includes: using a liquid level detection device to detect a first liquid level of the coating liquid circulation tank at the start time point of the target time period and a second liquid level of the coating liquid circulation tank at the end time point of the target time period, that is, using a liquid level detection device to detect a first liquid level of the coating liquid circulation tank at a first time and a second liquid level of the coating liquid circulation tank at a second time; and determining the liquid level change according to the first liquid level and the second liquid level. The first time corresponds to the first liquid level, and the second time corresponds to the second liquid level.

[0064] In step S3, the coating liquid consumption is determined according to the inner bottom area, the coating liquid density and the liquid level change. The coating liquid consumption refers to the consumption of the coating liquid within the target time period.

[0065] In step S4, the strip passing area is determined according to the strip speed, the strip width and the target time period. The strip passing area refers to the area of ​​the strip passing through the coating machine within the target time period.

[0066] In step S5, the first strip coating amount is determined according to the coating liquid consumption, the strip passing area and the drying ratio coefficient. The first strip coating amount refers to the coating amount per unit area of ​​the strip within the target time period.

[0067] In some embodiments, the method further includes: determining a second steel strip coating amount according to at least three of the first steel strip coating amounts. The at least three first steel strip coating amounts may be first steel strip coating amounts corresponding to at least three consecutive target time periods. Determining the second steel strip coating amount according to multiple first steel strip coating amounts can reduce the impact of abnormal data on the coating amount, and the coating amount can be determined with higher accuracy.

[0068] In some embodiments, the determining of the second steel strip coating amount according to at least three of the first steel strip coating amounts includes: determining the maximum value, the minimum value and the first sum of at least three of the first steel strip coating amounts; determining the second sum of the maximum value and the minimum value; determining the first difference between the first sum and the second sum and the second difference between the corresponding number of the first steel strip coating amount and 2; determining the second steel strip coating amount according to the first quotient of the first difference and the second difference. Remove the maximum value and the minimum value of the at least three first steel strip coating amounts, and then determine the average value of the remaining first steel strip coating amounts, so as to determine the second steel strip coating amount. Removing the maximum value and the minimum value can be understood as removing abnormal data, so as to determine the coating amount with higher accuracy.

[0069] In some embodiments, determining the coating liquid consumption according to the inner bottom area, the coating liquid density and the liquid level change includes: determining the coating liquid consumption according to the product of the inner bottom area, the coating liquid density and the liquid level change. The product of the inner bottom area and the liquid level change is the volume of the consumed coating liquid, and the coating liquid consumption is the product of the volume of the consumed coating liquid and the coating liquid density, that is, the mass of the consumed coating liquid.

[0070] In some embodiments, the determining of the strip passing area according to the strip speed, the strip width and the target time period includes: determining the single-sided strip passing area according to the product of the strip speed, the strip width and the corresponding time length of the target time period; determining the strip passing area according to the product of the single-sided strip passing area and 2. The single-sided strip passing area refers to the area of ​​the upper surface of the strip or the lower surface of the strip passing the coating machine. Since the area of ​​the upper surface of the strip passing the coating machine is the same as the area of ​​the lower surface of the strip passing the coating machine, the single-sided strip passing area multiplied by 2 is the strip passing area.

[0071] In some embodiments, determining the first strip coating amount based on the coating liquid consumption, the strip passing area and the drying ratio coefficient includes: determining a second quotient based on the coating liquid consumption and the strip passing area; determining the first strip coating amount based on the product of the second quotient and the drying ratio coefficient.

[0072] In some embodiments, the formula for determining the coating amount of the first strip coating is as follows: T = k*(ρ*S*Δh) / (2*v*Δt*W), wherein T is the coating amount of the first strip coating, ρ is the coating liquid density, S is the inner bottom area, Δh is the change in the strip liquid level, v is the strip speed, Δt is the duration corresponding to the target time period, and W is the strip width.

[0073] In some embodiments, the unit of k is %, the unit of T is g / m3, the unit of ρ is g / cm3, and the unit of S is m 2 , Δh is in m, v is in m / min, Δt is in s, and W is in mm, the formula for determining the coating amount of the first strip steel is as follows: T = k*6*10 10 *(ρ*S*Δh) / (2*v*Δt*W).

[0074] According to a second aspect of the present application, a coating amount alarm method is provided, comprising:

[0075] Determine the coating amount of the first steel strip coating according to a coating amount determination method according to any embodiment of the first aspect of the present application;

[0076] Whether to alarm is determined according to the coating amount of the first steel strip coating and the target value.

[0077] In some embodiments, determining whether to alarm based on the first steel strip coating amount and the target value includes: determining a first threshold value and a second threshold value based on the target value, wherein the first threshold value is greater than the second threshold value; if the first steel strip coating amount is less than or equal to the first threshold value and greater than or equal to the second threshold value, no alarm is issued; if the first steel strip coating amount is greater than the first threshold value or less than the second threshold value, an alarm is issued.

[0078] In some embodiments, determining whether to alarm based on the coating amount of the second steel strip and the target value includes: determining a first threshold and a second threshold based on the target value, wherein the first threshold is greater than the second threshold; if the coating amount of the second steel strip is less than or equal to the first threshold and greater than or equal to the second threshold, no alarm is issued; if the coating amount of the second steel strip is greater than the first threshold or less than the second threshold, an alarm is issued.

[0079] When the first coating amount or the second coating amount is not between the first threshold and the second threshold, an alarm is given, that is, the strip coating amount does not meet the requirements and needs to be adjusted. When the strip coating amount is too little, that is, the strip coating is too thin, the coating roller pressure can be reduced, and when the strip coating amount is too much, that is, the strip coating is too thick, the coating roller pressure can be increased.

[0080] In some embodiments, determining the first threshold and the second threshold based on the target value includes: obtaining a threshold percentage; determining a threshold product of the target value and the threshold percentage; determining the first threshold based on the sum of the target value and the threshold product; determining the second threshold based on the difference between the target value and the threshold product.

[0081] In the present application, on the one hand, the coating liquid consumption is determined according to the inner bottom area, the coating liquid density and the liquid level change, and on the other hand, the strip passing area is determined according to the strip speed, the strip width and the target time period; thereby, the first strip coating amount is determined according to the coating liquid consumption, the strip passing area and the drying ratio coefficient, and then according to the first strip coating amount, it is determined whether the strip coating is too thick or too thin, so as to control the strip coating amount and ensure the strip coating quality.
