[0038] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

For example, some operations / steps may be decomposed, while others may be combined or partially combined. Therefore, the actual execution order may vary depending on the actual situation.
[0042] It should also be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or precedence.

[0043] In steel cold-rolled tinning lines, the electroplating line is the terminal unit for the export of finished tinned coils and is a key link in quality control. The electroplating line uses a variety of solutions to clean and process the strip surface, thereby improving the strip's corrosion resistance, aesthetics, and weldability. Controlling the solution concentration plays a crucial role in ensuring strip production quality.
[0044] In the related art, during the strip steel production process, due to the lack of concentration detection equipment, it is impossible to perform online detection of the solution concentration, that is, to detect the solution concentration on the strip steel production line. For example, the solution concentration control method of the electrotin plating unit depends on the medium inspection report. The operation area stipulates that the process solution is inspected once every four hours. The production line operator can only mechanically adjust the solution concentration according to the medium inspection report every four hours. The solution concentration adjustment cycle is long and the solution concentration cannot be effectively and timely controlled. The solution concentration exceeds the standard rate by more than 60%.
[0045] It can be seen that the traditional mechanical solution control method is very passive, the solution concentration fluctuates greatly and the continuity of concentration control is poor. Since the solution concentration cannot be detected in real time and adjusted and controlled in time, it is easy to cause quality problems such as white spots in alkali washing, over-pickling of strip steel, DR16 marks, DR16a roller marks, and blue edges of passivation, which seriously affect the stability of product quality; and the irregular adjustment of the solution causes a lot of solution waste, resulting in an increase in the solution cost per ton of steel.
[0046] Therefore, in order to reduce the error correction adjustment cycle of solution concentration and effectively ensure the stability of solution concentration control, an embodiment of the present application provides a solution concentration adjustment method, which can detect and adjust the solution concentration online in real time, thereby improving the timeliness, stability and effectiveness of solution concentration adjustment.
[0047] The solution concentration adjustment method of the embodiment of the present application will be described below with reference to specific drawings.
[0048] Figure 1 A flow chart of a method for adjusting solution concentration according to an embodiment of the present application is shown.
[0049] like Figure 1 As shown, according to one aspect of an embodiment of the present application, a solution concentration adjustment method is provided, which can be executed on a computer in an industrial site where a tin plating unit processes steel strips. The method includes but is not limited to:
[0050] Step S10. During the process of processing the steel strip based on the target solution, detecting a conductive parameter of the target solution, wherein a predetermined mapping relationship exists between the conductive parameter and the concentration of the target solution;
[0051] For example, the target solution may be an alkaline washing solution, a pickling solution, a passivation solution, or other solution known in the related art for processing steel strips.
[0052] In some embodiments, a conductivity parameter is used to characterize the conductive properties of a target solution. The conductivity parameter includes conductivity and / or resistivity. The conductivity or resistivity of a solution reflects the salinity of the solution. For example, the higher the purity of the water and the lower the salinity, the lower the conductivity and the greater the resistivity.
[0053] Conductivity is a physical quantity that measures a solution's ability to conduct electricity. It represents the conductivity per unit length and cross-sectional area, typically measured in Siemens per meter (S / m). It reflects the number of ions in a solution and their mobility. Resistivity, the reciprocal of conductivity, describes a material's ability to resist the passage of electric current. This means that a solution with high conductivity will have low resistivity. Resistivity is typically expressed in ohm-meters (Ω-m).
[0054] Generally speaking, the more freely mobile ions there are in the target solution, the greater the ion concentration, and the higher the conductivity. It is understandable that the relationship between the conductivity of the target solution and the solution concentration is not simply linear, but also depends on the type of electrolyte in the solution and the concentration level. For example, for dilute solutions, at lower concentrations, as the electrolyte concentration increases, the number of ions in the solution increases, resulting in an increase in conductivity. For concentrated solutions, when the concentration continues to increase to higher levels, although the total number of ions increases further, due to the enhanced interactions between ions (such as ion pair formation or increased frequency of inter-ion collisions), these effects may restrict the free movement of ions, resulting in a slowdown or even a decrease in the rate of increase in conductivity. In addition, for different types of electrolytes, such as strong electrolytes, the conductivity increases with increasing concentration due to almost complete dissociation into ions, but may reach a peak at extremely high concentrations and then decrease slightly; while for weak electrolytes, due to partial dissociation, the conductivity depends not only on concentration but also on the degree of dissociation. It increases with increasing concentration within a certain range, but is generally lower than that of strong electrolytes.
[0055] This shows that the concentration of ions in the target solution indirectly affects the solution's conductivity. Changes in the solution's dielectric parameters satisfy ionic dynamic equilibrium, meaning that changes in ion concentration lead to changes in the solution's conductivity. The relationship between ion concentration and conductivity parameters maintains a dynamic equilibrium. Furthermore, the solution temperature target is quantitative and can be considered to have minimal fluctuations, with a negligible impact on conductivity. Therefore, the solution concentration can be determined based on conductivity.
[0056] On the basis of the above, in order to obtain a dynamic equilibrium relationship between the ion concentration and the conductive parameters of the target solution, the embodiment of the present application establishes a mapping relationship between the solution concentration and the conductive parameters through a sufficient amount of sample analysis, thereby making the dynamic equilibrium relationship between the solution concentration and the conductive parameters explicit, which is conducive to the subsequent online adjustment of the solution concentration based on the conductive parameters.
[0057] In some embodiments, before detecting the conductivity parameter of the target solution, the method further comprises:
[0058] Step S01. During the process of processing the steel strip based on the target solution, detecting the conductive parameter data of the target solution at intervals of a first time, and sampling the target solution to obtain a solution sample;
[0059] For example, during the process of processing the steel strip based on the target solution, the target solution is sampled at a certain interval, where the certain interval can be 2 hours, 3 hours, 4 hours, or 5 hours, and is not limited here. The concentration of the sampled solution is tested offline, that is, the concentration test is not performed on the steel strip production line, to obtain solution concentration data of the solution sample. In this way, a solution concentration test table of the medium can be obtained based on each solution sample, as shown in Table 1.
[0060] Table 1 Solution concentration test table
[0061]
[0062] It is understandable that the conductivity of the target solution may be different when the medium is different. Therefore, it is necessary to test the concentration of solutions containing different media. For example, the media include alkaline spraying, electrolytic spraying, pickling, pre-plating, Flux (flux), surface treatment liquid, etc. The solutions of different media are sampled multiple times and the concentration of the solution is recorded at each sampling.
[0063] Step S02. Obtaining the conductive parameter data and the corresponding solution concentration data at each sampling moment, wherein the solution concentration data is obtained by performing offline detection on the solution sample;
[0064] Step S03: establishing the mapping relationship according to each of the conductive parameter data and the corresponding solution concentration data.
[0065] It can be understood that when sampling the target solution, the conductivity or resistivity at that time is recorded at the same time. Thus, by obtaining several conductivity data of a certain medium and the corresponding solution concentration data, through data analysis, the mapping relationship (dynamic equilibrium relationship) between the conductive parameters and the solution concentration can be obtained.
[0066] In some embodiments, the mapping relationship may be recorded in a mapping relationship table, that is, the mapping relationship table records a plurality of the conductive parameters and the solution concentration corresponding to each conductive parameter.
[0067] Figure 2 A dynamic relationship diagram showing the correlation between conductivity and solution concentration in an embodiment of the present application. Figure 2 It can be seen that the fluctuation trends of conductivity and free oxygen concentration are very similar, showing a strong correlation.
[0068] Step S20. Determine whether the conductive parameter is within a preset conductive parameter range. If not, add a concentration adjusting medium to the target solution until the conductive parameter enters the conductive parameter range, wherein the conductive parameter range and the preset solution concentration range satisfy the mapping relationship, and within the solution concentration range, the processing performance of the target solution on the strip meets the production standard.
[0069] It is understandable that in order to ensure the quality of the strip steel production line, the production line has pre-established production standards. The production standards can be standards implemented by the strip steel production enterprise itself or industry standards, which are not limited here. Therefore, the solution concentration of the target solution needs to be maintained in a certain solution concentration range, for example, the target alkali solution concentration is 32±5g / L, that is, 27g / L-37g / L. Through the above mapping relationship, it can be known that if the solution concentration is maintained within the preset solution concentration range, the corresponding conductivity parameter range can be 37.5ms / cm-42.5ms / cm.
[0070] In some embodiments, the solution temperature is automatically controlled by the system according to the temperature setting to stabilize at 60±10°C, and the current density is automatically controlled by the system according to the temperature setting to stabilize at 18±3A / dm2, and the solution concentration is adjusted by detecting the conductivity.
[0071] In some embodiments, the conductivity parameter range includes a parameter upper limit value, and if not, adding a concentration adjusting medium to the target solution until the conductivity parameter enters the conductivity parameter range, comprising:
[0072] If the conductivity parameter is greater than the parameter upper limit, add diluent to the target solution at least once, and detect the conductivity parameter after each addition of the diluent until the conductivity parameter enters the conductivity parameter range, and stop adding the diluent to the target solution.
[0073] Exemplarily, the upper limit of the parameter may be a conductivity of 42.5 ms / cm, and the diluent may be desalted water.
[0074] It can be understood that when the conductivity parameter exceeds the upper limit of the parameter, it means that the solution concentration is too high and needs to be diluted. By adding desalted water to the target solution, adding a certain amount each time, for example, 500L, a stirring device can also be configured for rapid stirring. After adding the desalted water, the conductivity of the target solution is tested at a certain interval, for example, one minute, until the conductivity enters the conductivity parameter range after a certain addition of desalted water, and the addition of desalted water is stopped.
[0075] In some embodiments, the conductivity parameter range includes a parameter lower limit, and if not, adding a concentration adjusting medium to the target solution until the target conductivity parameter enters the conductivity parameter range, comprising:
[0076] If the conductivity parameter is less than the parameter lower limit, the solute is added to the target solution at least once, and the conductivity parameter is detected after each addition of the solute until the conductivity parameter enters the conductivity parameter range, and then the solute is stopped from being added to the target solution.
[0077] Exemplarily, the upper limit of the parameter may be a conductivity of 37.5 ms / cm, and the solute may be an alkali solution.
[0078] It can be understood that when the conductivity parameter is lower than the lower limit of the parameter, it means that the solution concentration is too low and the solution concentration needs to be increased. By adding alkali solution to the target solution, adding a certain amount each time, for example, 30L, a stirring device can also be configured for rapid stirring. After adding the alkali solution, the conductivity of the target solution is tested at a certain interval, for example, one minute, until the conductivity enters the conductivity parameter range after a certain addition of alkali solution, and the addition of alkali solution is stopped.
[0079] In some embodiments, the step of adding a concentration adjusting medium to the target solution comprises:
[0080] A concentration adjusting medium is added to the target solution at least once within a second time period, wherein the second time period is less than or equal to a preset time period, the at least one time is less than or equal to a preset number of times, and within the preset time period and the preset number of times, the concentration change of the target solution has an impact on the quality of the strip that is less than or equal to a preset impact.
[0081] For example: the maximum number of times the medium is replenished within a time limit of 15 minutes is no more than 3 times, so as to prevent the detection error of the conductivity detection instrument from causing the replenishment error, which will affect the quality of the strip steel, and also prevent the concentration change of the circulation tank solution and the delay error of the detection value from causing excessive replenishment.
[0082] For ease of understanding, the above conductivity adjustment process is described below by way of example:
[0083] 1) During the process of processing the steel strip based on the target solution, detecting the conductivity value in real time;
[0084] 2) Execute the first if-else (yes-no) process control: determine whether the online conductivity exceeds the conductivity parameter range [37.5, 42.5] ms / cm;
[0085] 3) If the conductivity does not exceed [37.5,42.5]ms / cm, it means that the solution concentration is at the standard state and no adjustment is required. Continue to test the conductivity;
[0086] 4) If the conductivity exceeds [37.5, 42.5] ms / cm, execute the second if-else flow control, that is, first determine whether the conductivity exceeds 42.5 ms / cm, so as to determine whether the solution concentration exceeds the upper limit of 37 g / L);
[0087] 5) If the upper limit is exceeded, it means that the solution concentration is too high. Execute the dilution concentration program to compensate for the desalted water, adding 500L each time, stirring the proportioning circuit rapidly, and judge the conductivity data every one minute (the interval time can be flexibly set according to the proportioning reaction of the production line solution);
[0088] 6) If the solution concentration does not exceed the upper limit and is not within the target conductivity parameter range, indicating that the solution concentration is below the lower limit of 27g / L, execute the concentration increase procedure to compensate for the alkali solution, adding 30L at a time, and stir the proportioning circuit rapidly. Analyze the conductivity data every one minute (the interval time can be flexibly set according to the production line control requirements and the solution proportioning reaction);
[0089] 7) Execute the third if-else process control: take the conductivity every one minute (the interval time can be flexibly set according to the production line control requirements and the solution ratio reaction) to determine whether the conductivity parameter range has been restored;
[0090] 8) If the conductivity parameter range is restored, it means that the solution concentration is in the standard state and no adjustment is required. Keep testing.
[0091] 9) If the conductivity parameter range is not restored, return to the loop to execute the second if-else process control, and set the upper limit of the number of rehydration executions within the time limit of 15 minutes to no more than 3 times to prevent instrument detection errors and rehydration errors caused by changes in the circulation tank solution concentration and detection value delay errors. Excessive rehydration.
[0092] 10) Circulate until the solution concentration recovers to the conductivity parameter range and maintain the online detection state.
[0093] For ease of understanding, the above conductivity adjustment process is described below in conjunction with Table 2.
[0094] Table 2 Conductivity-solution concentration data comparison execution table
[0095]
[0096]
[0097] Table 2 shows that, based on the real-time data recorded from actual production solutions, a conductivity-solution concentration data comparison table is generated, and the execution steps corresponding to each sampling moment are described. When the conductivity is in the range of [37.5, 42.5] ms / cm, it meets the operating standard and testing continues. When the conductivity exceeds the upper limit of 42.5 ms / cm, the solution concentration also exceeds the upper limit of the control standard of 37 g / L, requiring compensation with desalted water. When the conductivity falls below the lower limit of 37.5 ms / cm, the solution concentration also falls below the lower limit of the control standard of 27 g / L, requiring compensation with solute (alkali solution).
[0098] It has been verified that the solution concentration adjustment method in the embodiment of the present application can improve the efficiency of solution concentration adjustment compared with not using the solution concentration adjustment method. As shown in Table 3, a schematic table of concentration parameters before and after the solution is subjected to dynamic equilibrium adjustment is shown. Taking the alkaline spray solution as an example, the concentration parameters of some solutions listed in Table 3 before and after the dynamic equilibrium method are performed. Under the conditions of the concentration standard with an upper limit of 37g / L and a lower limit of 27g / L, the ratio of the data exceeding the upper and lower limits before the dynamic equilibrium control method is about 40-60%; using the solution dynamic equilibrium control method, the actual concentration of the solution is compared with the empirical concentration range estimated by the conductivity, and the deviation rate is kept within the error allowable range of no more than 0.1%, so that the solution concentration is relatively constant and stable in the effective range, the process solution concentration exceeding the standard rate is reduced to below 3%, the standardization of the solution concentration control is improved, the control method is more reliable, and the surface quality of the tinplate is effectively guaranteed.

[0101] Figure 3 A schematic diagram comparing the effects of the solution concentration adjustment method in the embodiment of the present application and the related art is shown.
[0102] In addition, it has been verified that the solution concentration adjustment method in the embodiment of the present application can improve the efficiency of solution concentration adjustment compared with the solution concentration adjustment method in the related art. Figure 3 As shown, a comparison is made between the offline mechanical solution concentration adjustment method in the related art and the online solution dynamic balance adjustment method of the embodiment of the present application. In terms of solution stability, the solution dynamic balance adjustment method of the embodiment of the present application shows that the solution concentration change trend is more stable and the fluctuation range is small; the mechanical solution control method in the related art shows that the solution concentration change trend is less stable and the fluctuation range is larger.

If not, a concentration adjustment medium is added to the target solution until the conductive parameter enters the conductive parameter range, wherein the conductive parameter range and the preset solution concentration range satisfy the mapping relationship, and within the solution concentration range, the processing performance of the target solution on the strip meets the production standard.
