【摘要】：应用激光诱导击穿光谱技术定性分析钢液中多元素的成分,并且结合自由定标法定量分析各元素的含量。为使检测结果更准确,加入一个平面镜反射装置,来减小自吸收现象。采集标准钢液样品中各元素的光谱,提取光谱强度,结合自由定标法建立样品中各元素的波尔兹曼平面,通过计算得到样品中各元素的含量,其中Mn元素的含量相对误差为22.178%,Fe元素含量相对误差为2.900%。实验表明实验值可以表征样品值,LIBS结合自由定标法可以对钢液中多元素成分进行定量分析。
[Abstract]:Laser induced breakdown spectroscopy was used to analyze the composition of multi-element in molten steel, and the content of each element was quantitatively analyzed by free calibration method. In order to make the detection results more accurate, a plane mirror reflector is added to reduce the self-absorption phenomenon. The spectra of each element in the sample of standard molten steel were collected, the spectral intensity was extracted, and the Boltzmann plane of each element in the sample was established with the free calibration method, and the content of each element in the sample was obtained by calculating the content of each element in the sample. The relative error of Mn and Fe is 22.178% and 2.900% respectively. The experiment shows that the experimental value can be used to characterize the sample value, and the LIBS combined with free calibration method can be used to quantitatively analyze the multi-element composition in molten steel.
