摘要
采用火花源原子发射光谱分析测定电工钢中超低C,研究试样制备方法、Ar纯度和压力等条件对分析结果的影响,并对工作曲线进行了优化,实现了一次分析同时测定电工钢的多种元素,满足炉前和精炼在线分析的要求。
Ultra - low carbon in electrical steel is determined with spark - source atom emission spectrum. It is researched the influence of sample making method, purity of Ar, and pressure on analysis result. The work curve is optimized. The determination of many elements in electrical steel only in one analysis is realized. It meets demands of on - line analysis for blast furnace and refining.
