Description

Technical Field

[0001] This invention belongs to the field of cold-rolled hot-dip galvanizing technology, specifically relating to a high-pressure cleaning control method, system, terminal, and storage medium for a finishing machine. Background Technology

[0002] With hot-dip galvanizing production lines typically producing a wide variety of products and specifications, color difference defects significantly hinder the production of high-surface-requirement appliance or automotive steel sheets. Hot-dip galvanizing lines employ wet finishing, which involves spraying finishing solution for lubrication during rolling. After finishing, a spiral high-pressure cleaner is used to rinse the roll surface. To ensure the roll surface is quickly cleaned and to reduce defects such as roll marks, the high-pressure cleaner typically uses 95-110 bar. After the rolls finish the strip surface, a large amount of zinc powder adheres to the roll surface. High-pressure water rinsing leaves rinsing marks, i.e., tire marks, on the roll surface. A mismatch between the support roll speed and the high-pressure cleaning carriage speed can lead to repeated high-pressure water rinsing of certain areas of the roll surface, exacerbating the tire marks. Uneven spraying of the finishing solution or an inappropriate conductivity can result in poor roll surface wettability, causing the support roll tire mark defects to be replicated on the sheet surface during rolling, resulting in downgraded products.

[0003] The current high-pressure rinsing process requires frequent adjustments and controls by personnel. These personnel must monitor and handle abnormal situations in real time, resulting in a heavy workload and a high probability of quality problems. There is an urgent need to establish a dynamic adjustment model for the high-pressure cleaning pressure and conductivity of the finishing fluid, as well as a speed control model for the high-pressure cleaning trolley, to achieve automatic control and parameter adjustment.

[0008] The running speed of the support roller and the distance from the nozzle to the roller surface are collected, and the running speed of the support roller and the distance from the nozzle to the roller surface are input into a pre-built speed control model to obtain the target speed of the high-pressure cleaning trolley.

[0009] The actual cleaning speed of the high-pressure cleaning cart is continuously monitored, and the operating status of the cleaning pump is controlled based on the comparison result between the actual cleaning speed and the preset threshold.

[0025] In one optional implementation, the continuous monitoring of the actual cleaning speed of the high-pressure cleaning cart, and the control of the cleaning pump's operating state based on a comparison between the actual cleaning speed and a preset threshold, includes:

[0027] If the actual cleaning speed is less than 50 m / min or equal to 0, the speed is determined to be abnormal and timing begins.

[0028] The timing time is compared with a preset time threshold. If the timing time reaches the time threshold, the cleaning pump is turned off and the operating status of the cleaning pump is recorded as off.

[0029] Secondly, the present invention provides a high-pressure cleaning control system for an optical finishing machine, comprising:

[0038] The curve fitting unit is used to perform curve fitting on the adaptation relationship between the high-pressure cleaning pressure and the conductivity of the finishing fluid, and obtain the relationship curve between the conductivity of the finishing fluid and the high-pressure cleaning pressure: y=0.1×(x-x0)+y0, where y is the target pressure, y0 is the lower limit of the pressure, x0 is the lower limit of the conductivity, and x is the current conductivity.

[0039] The rule storage unit is used to save the relationship curve as a cleaning pressure control rule.

[0040] In an optional implementation, the speed control model includes:

[0055] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0057] The high-pressure cleaning control method for the optical rectifier provided in this embodiment of the invention is executed by a computer device, and correspondingly, the high-pressure cleaning control system for the optical rectifier runs in the computer device.

[0058] Figure 1 This is a schematic flowchart illustrating a method according to an embodiment of the present invention. Wherein, Figure 1 The executing entity can be a high-pressure cleaning control system for a complete machine. Depending on different requirements, the order of steps in this flowchart can be changed, and some steps can be omitted.

[0059] like Figure 1 As shown, the method includes:

[0060] Step 110: Set the cleaning pressure control rules according to the compatibility between high-pressure cleaning pressure and the conductivity of the finishing solution;

[0061] Step 120: Collect the current conductivity of the polishing solution and the current cleaning pressure, and generate the target cleaning pressure based on the cleaning pressure control rule and the current conductivity of the polishing solution and the current cleaning pressure.

[0062] Step 130: Collect the running speed of the support roller and the distance from the nozzle to the roller surface, and input the running speed of the support roller and the distance from the nozzle to the roller surface into the pre-built speed control model to obtain the target speed of the high-pressure cleaning trolley;

[0063] Step 140: Continuously monitor the actual cleaning speed of the high-pressure cleaning cart, and control the operating status of the cleaning pump based on the comparison result between the actual cleaning speed and the preset threshold.

[0064] Step 150: If the cleaning pump is operating normally, adjust the cleaning pressure of the cleaning pump to the target cleaning pressure and adjust the cleaning speed of the high-pressure cleaning trolley to the target speed.

[0065] To facilitate understanding of the present invention, the high-pressure cleaning control method for the optical rectifier provided by the present invention will be further described below, based on the principle of the high-pressure cleaning control method for the optical rectifier and in conjunction with the process of controlling the high-pressure cleaning of the optical rectifier in the embodiments.

[0066] Specifically, the high-pressure cleaning control methods for the entire machine include:

[0067] S1. Set cleaning pressure control rules based on the compatibility between high-pressure cleaning pressure and the conductivity of the finishing fluid.

[0068] Orthogonal experiments were conducted using various high-pressure cleaning pressures combined with different conductivity levels of finishing solutions to obtain test data. From the test data, the compatibility between high-pressure cleaning pressures that resulted in no tire tracks and the conductivity levels of the finishing solutions was determined. The specific compatibility relationships are shown in Table 1.

[0069] Table 1

[0070] Conductivity / ms 295 305 342 384 422 456 477 514 559 613 667 724 765 793 852 High-pressure water pressure / bar 63 64 69 73 76 78 79 82 84 88 92 97 99 102 108

[0071] Curve fitting was performed on the adaptation relationship between high-pressure cleaning pressure and the conductivity of the finishing solution to obtain the relationship curve between the conductivity of the finishing solution and the high-pressure cleaning pressure: y = 0.1 × (x - x0) + y0, where y is the target pressure, y0 is the lower limit of pressure, x0 is the lower limit of conductivity, and x is the current conductivity. The relationship curve was saved as a cleaning pressure control rule.

[0072] S2. Collect the current conductivity of the polishing solution and the current cleaning pressure, and generate the target cleaning pressure based on the cleaning pressure control rules and the current conductivity of the polishing solution and the current cleaning pressure.

[0073] The current conductivity of the polishing solution and the current cleaning pressure are collected using corresponding sensors. The standard pressure range for the polishing solution is set to 4.5-5 bar, and the spray pressure of the polishing solution is controlled within this standard pressure range.

[0074] Please refer to Figure 2 For the dispersibility test of zinc powder in a certain type of brightening solution, the conductivity of the brightening solution in the range of 550-850ms showed the best effect on zinc powder dispersion. Therefore, the threshold range of conductivity of the brightening solution was set to 550-850ms.

[0075] Determine if the current conductivity of the finishing solution is within the threshold range: If the current conductivity is within the threshold range, continue calculating the target cleaning pressure; if the current conductivity is not within the threshold range, adjust the finishing solution spray parameters until the conductivity is within the range of 550-850ms. This ensures the effective dispersion of zinc powder.

[0076] Methods for calculating the target cleaning pressure include:

[0077] The current conductivity of the finishing fluid is incorporated into the cleaning pressure control rule to obtain the target cleaning pressure. Based on the difference between the current cleaning pressure and the target cleaning pressure, the actual cleaning pressure is adjusted to the target cleaning pressure.

[0078] S3. Collect the running speed of the support roller and the distance from the nozzle to the roller surface, and input the running speed of the support roller and the distance from the nozzle to the roller surface into the pre-built speed control model to obtain the target speed of the high-pressure cleaning trolley.

[0079] Speed ​​control model for high-pressure cleaning trolley: V = K × (100 - A%) / 100 × h × S / r

[0080] In the formula, K=1.3263; A is the tire print overlap rate; h is the distance from the nozzle to the roller surface; S is the running speed of the support roller; and r is the diameter of the support roller.

[0081] Among them, the tire print overlap rate A, the support roller diameter r, and K are all fixed parameters that are pre-imported into the model.

[0082] The distance h from the nozzle to the roller surface and the running speed S of the support roller are obtained by the production line sensors. h and S are input into the speed control model to obtain the target speed V.

[0083] S4. Continuously monitor the actual cleaning speed of the high-pressure cleaning cart, and control the operating status of the cleaning pump based on the comparison result between the actual cleaning speed and the preset threshold.

[0084] Considering that the production line speed for all specifications of hot-dip galvanized strip steel is above 50m / min, any speed below this is considered an abnormal speed reduction. When this occurs, the roller system operates at a low speed, resulting in a longer time spent at the same position on the high-pressure cleaning spray roller surface. This reduces the zinc powder enrichment at the corresponding position on the roller system, leading to tire-print color differences. The program limits pump start-up conditions based on speed. If the speed is below 50m / min or the high-pressure cleaning trolley's operating speed is 0 for 5 seconds (considered a jam), the high-pressure water pump will automatically shut down. Furthermore, a jam-induced pump stop is only implemented when the distance between the weld seam and the finishing machine exceeds 5 meters, preventing roller print defects caused by stopping the pump at the weld seam.

[0085] Specifically, confirm that the distance between the cleaning machine and the weld is greater than 5m; if the actual cleaning speed is less than 50m / min or equal to 0, then the speed is determined to be abnormal and timing begins; compare the timing time with the preset time threshold, and if the timing time reaches the time threshold, then turn off the cleaning pump and record the operating status of the cleaning pump as off.

[0086] S5. If the cleaning pump is running normally, adjust the cleaning pressure of the cleaning pump to the target cleaning pressure and adjust the cleaning speed of the high-pressure cleaning trolley to the target speed.

[0087] If the cleaning pump is operating normally, adjust the cleaning pressure of the cleaning pump to the target cleaning pressure and adjust the cleaning speed of the high-pressure cleaning trolley to the target speed.

[0088] If the cleaning pump is off, no control procedure is required.

[0089] In some embodiments, the high-pressure cleaning control system of the optical rectifier may include multiple functional modules composed of computer program segments.
