Abstract
The invention discloses a spectrum detection method for components of a rod wire in the diameter not larger than 14 mm. The spectrum detection method comprises the following steps that (1) preparing an excitation panel in the pore diameter of 6 mm; 2) preparing an eccentric standard sample; 3) drawing a special analysis curve of a standard sample; 4) preparing a sample; 5) covering a detection hole in the pore diameter of 6mm by the sample; 6) carrying out excitation, and comparing spectrum data with the 6mm standard analysis curve; and 7) obtaining a detection result. The problems that the small-specification wire rod cannot be subjected to spectral detection and a small sample mold is limited when being used for spectral detection are solved, and rapid accurate analysis on the rod-shapedsample in the diameter not greater than 14mm is realized.
Description
technical field [0001] The invention belongs to the technical field of material analysis, and in particular relates to a spectral detection method for components of rods and wires with a diameter not greater than 14mm. Background technique [0002] The aperture of the excitation platform for spectral analysis is 12mm. For rods and wires with a diameter of less than 14mm, it cannot be directly detected by spectrum, because the spectral component analysis requires that the excitation point be on the circumference of the 1 / 4 section of the rod and wire, so the rods and wires with a diameter of less than 14mm Rods and wires cannot process eccentric samples. In addition, samples smaller than this diameter cannot cover the excitation hole, and the excitation cannot be excited due to the influence of protective gas leakage during excitation. [0003] In the process of realizing the present invention, the inventor has found that the prior art has at least the following problems: th...
