摘　　要：为配合河北理工学院和唐山钢铁公司合作开发新项目—连铸准沸腾钢的研制，研究试验了还原硅钼酸盐分光光度法测定非合金钢和纯铁中微量硅。改进后该方法简单、适用。且由此法测得结果与等离子体发射光谱得到的分析结果一致，应用于实际生产中结果满意。本方法适用于非合金钢和纯铁中硅含量在０．００３％～０．Based on the references and the international standard method,an improved method is studied in this paper to determine microsilicon in nonalloy steel and pure iron with reducing silicomolybdate by spectrophotometry.The new method is more practical and simpler.The experimental result is satisfactory and is in keeping with that tested by ICPemission spectrometry.
