江苏铜山利国古代冶铁遗址初步调查

Preliminary Investigation on Ancient Iron Smelting Site Found at Liguo Village of Xuzhou City,Jiangsu Province

铜山利国古代冶炼遗址位于江苏省徐州市铜山区利国镇中心的珍珠泉附近,对两处遗址进行田野调查并获取炉渣、矿石等冶金遗存。采用X射线荧光光谱仪分析(EDX)、扫描电镜及能谱分析(SEM-EDS)、金(矿)相观察等科学试验方法,对17个炉渣等样品进行检测分析,结合炉渣的化学成分与显微组织探讨该遗址的冶炼性质与技术特征。试验结果表明,其中一处遗址为冶铁遗址,技术类型为生铁冶炼,炼铁渣属于硅钙铝系高钙炉渣;另一处遗址有高铁炉渣遗存,综合判断很可能是生铁炒钢炉渣。

Liguo smelting sites is located near the Pearl Spring in the center of Liguo town,Tongshan district,Xuzhou city,Jiangsu province.Through field investigation of Liguo smelting sites ancient metallurgical remains such as slag and ore were obtained.These remains were tested and analyzed by various scientific experimental methods such as metallographic(mineral)observation,energy spectrum analysis(EDX),and scanning electron microscope(SEM-EDS).Based on chemical composition and microstructure of slag,the smelting properties and technical characteristics of the smelting site were discussed.The results show that the Liguo smelting site can be judged to be an iron smelting site and the technology involved is cast iron smelting.The iron smelting slag can be characterized into Si-Ca-Al series high-calcium slag.At the same time,signs of high-iron slag are found in another part of the site.It is possible that the slag comes from puddling process.
