一件战国时期青铜鼎鼎耳的铸接工艺研究

Connecting Casting Technique of the Handle and the Body of the Bronze Ding from Warring States Period

应用X射线荧光光谱分析及金相显微观察对湖北省襄樊陈坡M10战国楚墓出土的一件青铜鼎的耳部连接标本进行了化学成分测试及金相组织检验。结果表明:已铸附件的表面处理或整型是分铸铸接工艺中一个重要的环节;分铸铸接是一种依靠浇铸主体时铜液凝固收缩致使附件紧贴主体的机械式连接。结合相关文献对此铸接工艺流程进行了探讨。

The X-ray spectrofluorimetry （XRF） and metalloscopy were employed to analyze the joint between the handle and the main body of the bronze Ding that was unearthed at Chu tomb of Warring States period, located in Xiangfan city, Hubei province. Results show that the cleaning or finishing the surface of the handle cast separately is an important procedure in the separate casting technique. The bronze Ding was formed by connecting casting between the handle and the body of the bronze Ding, which was realized by teeming copper liquid for the body of the Ding into the moulding cavity with the handle cast separately that was embedded into it along with clay core beforehand, to make the handle and the body clung together by means of freezing shrinkage of copper liquid. A preliminary analysis on the technological process was given in this paper.
