Description

Technical Field

[0001] The utility model relates to the technical field of automatic analyzers for steel inclusions, and particularly relates to a sample stage of an automatic analyzer for inclusions with adjustable height. Background Art

[0002] An automatic analyzer for steel inclusions can automatically and quickly identify, analyze, and classify and count inclusions in steel, including the morphology, size, composition, and classification of inclusions, the distribution of inclusions, the composition and content information of different types of inclusions, reflect the composition distribution of all inclusions in a custom ternary distribution map, reposition specific inclusions, and perform compositional surface distribution scanning.

[0003] Currently, for the sample stage of the automatic analyzer for inclusions, in order to obtain accurate data, it is required that the heights of the samples to be tested are roughly the same. However, in practice, there are often situations where the heights of the samples to be tested vary greatly. Samples with large height differences need to be tested in batches. When using the automatic analyzer for inclusions to test samples each time, it is necessary to evacuate the air, and when changing samples after the test, it is necessary to release the vacuum, which wastes time, limits the test efficiency, and increases the experimental cost. Generally, when testing samples with different heights, it is impossible to test multiple samples simultaneously and adjust the height flexibly. Designing a sample stage of an automatic analyzer for inclusions with adjustable height is very necessary for its test accuracy and test efficiency. Moreover, when detecting inclusions, it is very important to keep the detection surface of the detection sample horizontal to ensure that the focus does not deviate significantly from the normal position, so that the inclusions in the detected field of view can be accurately identified and analyzed, thereby ensuring the reliability of the analysis results.
