世界铜鼓之王──北流型101号铜鼓铸造工艺研究

A research on the casting technique of No.101 Beiliu bronze drum──the king of bronze drums in the world

体大壁薄的世界铜鼓之三──北流型101号铜鼓是世界上迄今所见最大的一面铜鼓，具有相当大的铸造难度。本文对北流型101号铜鼓的内外陶范及鼓耳的制作方法、内范结构、在外范上直接制作纹饰的方式、浇注工艺和垫片的使用等古代铸造工艺进行了研究。还探讨了该铜鼓的结构特征及鼓足残缺的成因。

The No.101 Beiliu bronze drum with big body and thin wall tnickness was called the king of bronze drums in the world. It is a bigest bronze drum in the world at present and very hard for casting.In the base of thoroughgoing, careful investigated and first duplicate experiment, this paper researches the ancient casting techniques of this bronze drum: the manufacture method of inner and outer clay moldes and wax ears of drum, the inner clay mold (core) structure, the moldes of making patterns ditectly on the outer clay mold surface, the casting plan and use of the spacers (chaplets) et al. In addition to the structure features of this bronze drom and the incomplete reasons of drum foot are studied.
