| 中文摘要 | 为了实现钢铁等金属熔炼过程中实时、在线监测元素组分含量,设计了一种远程双脉冲激光诱导击穿光谱(LIBS)分析系统,对远距离的样品进行非接触式远程测量、成分分析。首先利用固体标准钢样对系统进行了测试以及标定,为下一步利用此系统在线监测熔融钢液组分含量提供了基础。实验结果表明:激光远距离聚焦光斑在1 mm左右;双脉冲烧蚀比单脉冲烧蚀深度深很多;双脉冲最佳延时在不同距离下不一致;3.1 m处双脉冲增强效果比2.1 m处更好,其中Ti(Ⅰ)319.99 nrn增强最显著为5.19倍;各种元素的标定曲线相关系数r都在0.99左右,重复精度(RSD)基本都小于5%,测量偏差(RMSE)都小于0.021%,2.1m处的检出限相比3.1 m处更低,2.1 m处多数元素检出限小于500 ppm。 |
| 英文摘要 | In order to realize real-time, online monitoring of the component of steel and other metal smelting process, we designed a remote double-pulse laser-induced breakdown spectroscopy (LIBS) analysis system which can realize non-contact remote measurement and component analysis for long distance sample. The paper first tests the system on solid standard steel samples, which provides basis for online monitoring the component of molten steel. The experimental results show:laser focal spot is about 1mm in long distance; double-pulse ablation depth is deeper than single pulse's; the optimum delay of double-pulse is non-consistent in different distances; the enhancement effect of double- pulse in 3.1 m is better than that in 2.1 m, and the maximum enhancement is 5.19 of Ti(I) 319.99 nm; the calibration curve of R2is about 0.99, RSD being less than 5%, RMSE being less than 0.021%, LOD being less than 500 ppm for most elements in 2.1 m, which is better than that in 3.1 m. |
