Description

TECHNICAL FIELD

[0002] Direct reading spectrometer has the advantages of simultaneous analysis of multiple elements, fast, accurate, simplified analysis process, etc., and is widely used in chemical composition analysis of metal materials. When spark analysis is performed using a direct reading spectrometer, sample preparation is crucial to spectral analysis, directly affecting the accuracy and precision of the analysis results. According to the standards such as HB / Z206 "Sampling Specification for Spectral Analysis of Steel and High Temperature Alloy" and HB / Z208 "Sampling Specification for Spectral Analysis of Non-ferrous Metal Materials", the surface of the test sample must be prepared before being analyzed by the instrument, and surface defects such as pits, oxidation layers, and contaminants that affect testing must be removed to achieve a smooth, clean, and appropriately rough surface for testing. However, the standard recommends that the metal thickness of the sample for spectral analysis should be greater than 3mm. For thin plate materials below 3mm, the content of each element can generally only be detected by conventional chemical analysis methods. Conventional chemical analysis methods require multiple reagents and have a long test cycle, resulting in low detection efficiency. Therefore, more and more users hope to use spectral analysis methods to quickly and accurately analyze the elements of metal sheets or strips below 3mm, especially the rapid composition analysis of stainless steel sheets.

[0003] Most of the currently disclosed solutions for preparing chemical samples of thin plate materials are designed to use mechanical clamping devices to achieve fixation and clamping during preparation. However, due to the thinness of the sample, the friction during polishing and the metal sparks and grinding heat generated during grinding make it difficult to clamp, resulting in poor operation stability and making it difficult to prepare a smooth surface that meets the excitation requirements. At the same time, there are also unsafe factors such as sample being thrown and mechanical damage during preparation.
