延庆山戎文化墓出土了一枚铜柄铁刀 ,时代约与春秋中期早段相当。从外形考察和扫描电镜能谱的分析情况看 ,其刀身当是块炼铁锻制的 ;从X射线探伤分析的情况推测 ,它很可能是先用块炼铁锻制刀身 ,之后再浇铸铜柄 ,而合铸成型的。这是山戎文化区年代最早的铁器 ,也是我国今见年代较早的铁器之一 ,对我们了解早期铁器的冶炼和成型工艺都具有积极的意义。 Yanqing Shan Rong Tomb unearthed a copper handle iron knife, about the same age and early spring and mid-term quite. From the appearance and scanning electron microscopy analysis of the situation, the blade is a piece of iron forging; from the X-ray analysis of the situation speculated that it is likely to be the first piece of iron forging blade, and then cast copper Shank, and molded. It is one of the earliest ironworks in the Shanrong Cultural District and one of the earlier ironworks in our country from the present age. It is of positive significance for us to understand the smelting and forming processes of the early ironworks.
