[0002] As is known, grain size is an important indicator to measure the quality of aluminum sheet and strip. Generally, the finer the grain, the better the room temperature mechanical properties of the sheet and strip, the better the plasticity and toughness, and the better the performance and surface quality can be obtained in the post-processing process. After finishing, aluminum sheet and strip with coarse grain structure will produce many coarse grain stripes along the rolling direction. It has a great impact on product quality, reduces the mechanical properties of materials, causes bending and cracking during use, and holes during punching. If aluminum foil is produced from aluminum plates and strips with coarse grain structure, the number of pinholes in the produced aluminum foil will increase. Therefore, it is necessary to frequently test the grain size of the product. The existing detection method generally has the following operating steps: ① on-site sampling; ② sending to a dedicated grain size detection room; ③ corroding with acid and washing with water; ④ observing the grain size of the sample and comparing the grain size spectrum; ⑤ grading; on-site sampling and transfer to a dedicated grain size detection room wastes a lot of time. If the inspector carries a pickling bottle for on-site inspection, once the pickling bottle leaks, it will threaten the life safety of the inspector.
