本文叙述用杯形铜电极溶液法进行平炉渣光谱分析的一些结果。实验用ПС-39型交流电弧作光源,硝酸溶解渣样,加SnCl2(Sn作内标)和KBr(K作燃烧稳定剂),并且把这溶液经过加热处理。再适当地选定了铜杯的大小和形状,和采用了直接照明系统。用固定定标曲线法作了20个渣样的硷度(Ca/Si)分析。与化学分析结果比较相差小于±5%。最后讨论了铜杯溶液法进行分析时定标曲线发生移动的原因和防止的方法,试样在硝酸溶液中溶解的问题,与试样溶液在燃烧过程中的翻腾现象。

Various procedures for spectrographic analysis of metallurgical slags have been found in the literature, but, in practice, results are often influenced by the chemical nature of the samples. This paper reports some results obtained on the spectrographic analysis of open-hearth slags by the copper cup-electrode solution method.
