本文运用扫描电子显微镜及能谱分析(SEM-EDS)等研究方法,对郑韩故城的炉渣样品进行科学分析。结果表明,炉渣可分三类,第一类炉渣为冶炼红铜产生的,第二类炉渣为冶炼金属铅产生的,第三类炉渣为熔炼锡青铜产生的。炉渣有合适的密度、硅酸度、熔点及良好的流动性,渣中金属量较低,熔炼的还原气氛较好。在此基础上,本文对冶炼工序及产品进行了分析和推断。 In this paper, the use of scanning electron microscopy and energy dispersive spectroscopy (SEM-EDS) and other research methods, the slag samples of the city of Cheng Han for scientific analysis. The results show that the slag can be divided into three categories, the first type of slag is produced by smelting copper, the second type of slag is produced by smelting metallic lead, and the third type of slag is produced by melting tin bronze. Slag has the appropriate density, silicic acid, melting point and good fluidity, the lower the amount of metal in the slag, smelting reduction atmosphere is better. On this basis, this article analyzes and concludes the smelting processes and products.
