Description

Technical Field

[0001] The utility model belongs to the technical field of test fixtures and relates to a test fixture used for analyzing residual dust on the surface of an aluminum plate. Background Art

[0002] After rolling, a lot of aluminum powder, dust and other particles still remain on the surface of the aluminum plate. Since aluminum is relatively soft compared to ferrous metals such as steel, these dusts will damage the surface of the plate. At the very least, the surface of the aluminum plate will have different colors, bright spots, etc. after rolling, and at worst, scratches, holes and other defects will appear. These defects may cause more plate defects during subsequent processing. Therefore, it is necessary to understand and analyze the content of residual aluminum powder and dust on the surface of the aluminum plate, so as to analyze the reasons why aluminum powder and dust remain on the surface of the aluminum plate, so as to further improve the rolling process of the aluminum plate. In addition, considering that these dusts may cause secondary pollution during the analysis process, it is necessary to design a test fixture that can prevent secondary pollution of the aluminum plate sample and ensure accurate experimental data.
