[0044] First, the application scenarios applicable to this application are introduced. The embodiments provided in this application are applicable to but not limited to the technical fields of strip steel and the galvanizing technology of cold-rolled strip steel surface. It has been found that in the cold rolling production process of strip steel, the surface of the strip steel needs to be galvanized to prevent corrosion of steel. Therefore, the quality of the zinc layer on the surface of the strip steel has a great influence on the product quality of the strip steel. In addition, in the process of galvanizing the strip steel, the air knife, as an important part of the galvanizing process, plays an important role in the quality of the zinc layer on the surface of the strip steel.

[0045] Based on this, the embodiments of the present application provide a method, device, electronic device and storage medium for galvanizing steel strip. The embodiments provided in the present application not only improve the quality of galvanizing steel strip, but also enhance the stability of air knife production, thereby improving the accuracy of galvanizing treatment of the steel strip to be processed and the stability of the steel strip product.

[0046] See also Figure 1 , Figure 1 This is one of the flow charts of a method for galvanizing a steel strip provided in an embodiment of the present application. Figure 1 As shown in the figure, the strip galvanizing treatment method provided in the embodiment of the present application comprises the following steps:

[0047] S101. Based on the target galvanizing task, obtain target parameters corresponding to the target air knife for galvanizing the steel strip to be processed.

[0048] In this step, in the embodiment provided in the present application, the operator will determine the target galvanizing task according to customer needs or other production needs, that is, which and what type of unprocessed steel strips need to be galvanized. At this time, after determining the target galvanizing task, it is necessary to determine the target air knife for galvanizing the above batches of unprocessed steel strips, as well as the target parameters corresponding to the target air knife.

[0049] Here, the type of target air knife in the embodiment provided in the present application can be customized according to different application scenarios and requirements. It is assumed that the target air knife in the embodiment provided in the present application is specifically but not limited to the Duma air knife angle.

[0050] Optionally, the above-mentioned target parameters include a target angle. The embodiment provided in the present application needs to ensure that the Duma air knife works in a relatively horizontal ideal state by determining the target angle of the Duma air knife, so as to avoid defects on the zinc layer on the surface of the strip caused by zinc slag splashing during the galvanizing process of the strip.

[0051] S102. Based on the steel type of the steel strip to be processed, determine a target insertion amount of the external zinc pot correction roller into the steel strip to be processed.

[0052] In this step, after determining the target parameters corresponding to the target air knife, the strip to be processed will not be directly galvanized. Instead, it is necessary to further determine the target insertion amount of the external zinc pot correction roller into the strip to be processed based on the steel type of the strip to be processed.

[0053] Here, due to the different steel types of the strip to be processed, the target insertion amount of the external zinc pot correction roller needs to be different. Therefore, determining the target insertion amount of the external zinc pot correction roller inserted into the strip to be processed of different steel types can avoid the strip from being scratched by the air knife due to large transverse bending.

[0054] Among them, the steel types in the embodiments provided in the present application can be customized according to different application scenarios and usage requirements. It is assumed that the steel types in the embodiments provided in the present application are classified according to the hardness of the steel type and are divided into three categories, namely: low carbon steel, ordinary carbon steel and high-strength steel.

[0055] S103. Based on the target parameters and the target insertion amount, control the target air knife to perform galvanizing on the steel strip to be processed.

[0056] In this step, after determining the target parameters and the target insertion amount in the embodiment provided in the present application, the target air knife is adjusted according to the target parameters, and the external steel zinc pot correction roller is inserted into the strip to be processed according to the specified target insertion amount according to the corresponding steel type, and then the galvanizing treatment of the strip to be processed is started.

[0057] Here, after determining and adjusting the target parameters and the target insertion amount, the zinc pressure can be strictly controlled to reduce the uneven thickness of the zinc layer on the surface of the strip when galvanizing the strip.

[0058] Optionally, step S101 includes the following sub-steps:

[0059] Sub-step 1011, based on the historical splash data of zinc particles in the historical galvanizing tasks, determine the preset splash data of the zinc particles when the to-be-processed steel strip is galvanized in the target galvanizing task.

[0060] In this step, the embodiment provided in the present application first obtains the historical spatter data generated by the historical batches of strip steel during the historical galvanizing task, and based on the mapping relationship (data mapping table) between the above historical spatter data, the historical air knife and the historical air knife angle corresponding to the historical air knife, or predicts or determines the preset spatter data of zinc particles when the strip steel to be processed is galvanized in the target galvanizing task.

[0061] Sub-step 1012: determining a target angle corresponding to a target air knife for galvanizing the steel strip to be processed based on the preset spatter data.

[0062] In this step, the embodiment provided in the present application determines the target angle corresponding to the target air knife according to the preset splashing data of zinc particles when the strip to be processed is subjected to galvanizing treatment and the above-mentioned data mapping table.

[0063] Optionally, the target parameter corresponding to the target air knife also includes a target position, where the target position is used to characterize the distance between the edge baffle of the target air knife and the strip to be processed. Therefore, step S101 in the embodiment provided by the present application also includes the following sub-steps:

[0064] Sub-step 1013: Based on the target galvanizing task, determine the distance between the edge baffle of the target air knife and the strip to be processed.

[0065] In this step, the strip galvanizing processing method in the embodiment provided in the present application also requires limiting the target position corresponding to the target air knife so that the edge baffle of the target air knife is parallel to the strip to be processed.

[0066] Sub-step 1014: when the distance satisfies a preset distance threshold range, determining the position of the target air knife as the target position.

[0067] In this step, the target position of the target air knife is determined by ensuring that the distance between the edge baffle of the target air knife and the strip to be processed meets a preset distance threshold range.

[0068] Among them, the target position of the target air knife in the embodiment provided in the present application can be customized according to different application scenarios and different strip processing requirements. It is assumed that the target position of the above-mentioned target air knife is specifically at a position 2-5mm away from the strip to be processed, and the target air knife at the target position is parallel to the strip to be processed.

[0069] In this way, the embodiment provided by the present application can adjust the horizontal position in time according to the changes of the center line of the air knife.

[0070] Optionally, the target parameters corresponding to the target air knife also include a target air knife pressure and a target air knife height. The target galvanizing task includes a target strip zinc layer thickness. Here, determining the target air knife pressure and target air knife height corresponding to the target air knife can better avoid Duma air knife streaks caused by zinc slag splashing and zinc flow lines caused by the target air knife pressure and target air knife height.

[0071] Therefore, step S101 in the embodiment provided by the present application also includes the following sub-steps:

[0072] Sub-step 1015, based on the target strip zinc layer thickness, determine the target air knife pressure and target air knife height corresponding to the target air knife for galvanizing the strip to be processed.

[0073] In this step, the target galvanizing task in the embodiment provided in the present application includes but is not limited to the steel type of the steel strip to be processed and the target strip zinc layer thickness. At this time, according to the preset target strip zinc layer thickness, the target air knife pressure matching the target strip zinc layer thickness is determined, and then the target air knife height corresponding to the target air knife is determined according to the target air knife pressure and the preset air knife height-air knife pressure mapping table.

[0074] Here, it is assumed that the preset air knife height-air knife pressure mapping table in the embodiment provided in this application is specifically as shown in the following Table 1:

[0075] Table 1

[0076]

[0077] It is assumed that the statistical unit of the target air knife height in the embodiment provided in the present application is mm, and the statistical unit of the target air knife pressure is MPa.

[0078] In the above, the embodiments provided in the present application can also control the target linear velocity of the target air knife, that is, the embodiments provided in the present application can also specifically include the target linear velocity, so that the target linear velocity satisfies the preset linear velocity rule, thereby realizing the target linear velocity adjustment of the target air knife.

[0079] Optionally, the target angle corresponding to the target air knife includes the target upper and lower blade body angles and the target upper and lower blade body angle difference. In this case, sub-step 1012 further includes the following sub-steps:

[0080] Sub-step 10121, based on the preset spatter data, determining the actual upper and lower blade angles and the actual upper and lower blade angle difference in the target air knife for galvanizing the steel strip to be processed.

[0081] In this step, the embodiment provided in the present application determines the corresponding actual upper and lower blade angles and the actual upper and lower blade angle difference in the target air knife according to the preset spatter data and the above-mentioned data mapping table.

[0082] Sub-step 10122: If the actual upper and lower blade body angles satisfy the first preset angle range, and the actual upper and lower blade body angle difference satisfies the second preset angle range, the actual upper and lower blade body angles are determined as the target upper and lower blade body angles corresponding to the target air knife, and the actual upper and lower blade body angle difference is determined as the target upper and lower blade body angle difference corresponding to the target air knife.

[0083] In this step, the embodiment provided by the present application needs to determine the relationship between the actual upper and lower blade body angles and the first preset angle range. If the actual lower blade body angle is within the first preset angle range (that is, the actual lower blade body angle satisfies the first preset angle range), the actual lower blade body angle is determined as the target upper and lower blade body angles corresponding to the target air knife; at the same time, the relationship between the actual upper and lower blade body angle difference and the second preset angle range is determined. If the actual lower blade body angle difference is within the second preset angle range (that is, the actual lower blade body angle difference satisfies the second preset angle range), the actual lower blade body angle difference is determined as the target upper and lower blade body angle difference corresponding to the target air knife.

[0084] Here, it is assumed that the first preset angle range of the Duma air knife in the embodiment provided in the present application is specifically -1° to -3°, and the second preset angle range of the Duma air knife is specifically 0.1° to 0.4°, so that the Duma air knife can be ensured to be in a relatively stable ideal state, avoiding slag defects in the strip caused by zinc slag splashing.

[0085] The following two embodiments illustrate the specific method of using the strip galvanizing treatment method to treat the strip to be treated:

[0086] Example 1: The production specification of the galvanizing unit is set to 0.68*1200 (thickness*width), and the steel type of the strip to be processed is M3A43:

[0087] Step 1: Adjust the upper blade angle of the Duma air knife to -2.1° and the lower blade angle of the Duma air knife to -1.9°.

[0088] Step 2: Make the distance between the edge baffle of the target air knife and the strip to be processed 3 mm, and adjust the edge baffle so that its position is straight with the strip.

[0089] Step 3: Adjust the target air knife pressure to 450 MPa and adjust the target air knife height to 380 mm.

[0090] Step 4: Adjust the target insertion amount of the external zinc pot correction roller into the strip to be processed, assuming that the strip to be processed is a low-carbon steel zinc pot roller insertion amount + 18mm, and the plate shape is straight.

[0091] Example 2: The production specification of the galvanizing unit is set to 0.9*1395 (thickness*width), and the steel type of the strip to be processed is M4A06:

[0092] Step 1: Adjust the upper blade angle of the Duma air knife to -2.0° and the lower blade angle of the Duma air knife to -1.8°.

[0093] Step 2: Make the distance between the edge baffle of the target air knife and the strip to be processed 2 mm, and adjust the edge baffle so that its position is straight with the strip.

[0094] Step 3: Adjust the target air knife pressure to 330 MPa and adjust the target air knife height to 300 mm.

[0095] Step 4: Adjust the target insertion amount of the external zinc pot correction roller into the strip to be processed, assuming that the strip to be processed is low-carbon steel zinc pot roller insertion amount + 160mm, and the plate shape is straight.

The embodiment provided by the present application obtains the target parameters corresponding to the target air knife for galvanizing the strip to be processed, and determines the target insertion amount of the external steel zinc pot correction roller into the strip to be processed based on the steel type of the strip to be processed, and then controls the target air knife to galvanize the strip to be processed according to the target parameters and the target insertion amount. While improving the galvanizing quality of the strip, the stability of the air knife production is enhanced, thereby improving the accuracy of the galvanizing of the strip to be processed and the stability of the strip steel product. The embodiment provided by the present application provides further guarantee for the quality of the strip products of the downstream production line, thereby meeting the needs of customers with higher standards.
