摘　　要：在铁水中加入0.1%硼促使全白口的前提下,采用阶梯式浇注系统、合理的合金元素加入顺序、特殊的冶炼和强制冷却工艺,研制出了光谱分析用合金铸铁标准物质。观察了试样金相显微组织。结果表明:该合金铸铁标准物质组织致密、白口化程度良好。经极差法和方差法检验,各元素均匀性良好。因此研制的该标准物质适用于合金铸铁在生产中的检验。The alloy cast iron reference material （RM） for spectral analysis, under the premise of 0.1% boron addition making absolute-white section, was developed by adopting step gating system, the reasonable joining order of alloy elements, special mould and forced cooling process. The metallographic structure of the samples were observed. The results indicate that the alloy cast iron reference materials have dense microstructure and absolute-white section. The homogeneity of each element exhibits well by the method of range and variance. So, the developed reference material can be used to the analysis of the alloy cast iron in oroduction.
