Abstract

The embodiment of the invention discloses a method for discriminating ancient cast iron and block ironmaking products, and belongs to the technical field of methods for discriminating ancient steel products. The method comprises two parts of metallographic analysis and non-metallic inclusion analysis of ancient cast iron and block ironmaking products. Wherein the metallographic analysis is used for distinguishing according to different room-temperature equilibrium structures of the ancient cast iron and the block ironmaking product, and the non-metallic inclusion analysis is used for the quantity, composition, morphology and distribution of non-metallic inclusions of the ancient cast iron and the block ironmaking product. Through collaborative analysis of alloy phase structures and inclusions, the method for accurately distinguishing ancient cast iron and block ironmaking products is obtained, and large-scale popularization and application are facilitated.

Description

technical field

[0001] The invention belongs to the technical field of discrimination methods for ancient iron and steel products, and in particular relates to a discrimination method for ancient cast iron and block ironmaking products based on the characteristics of inclusions. Background technique

[0002] From ancient times to the present, the production and circulation of iron have played an important role in the development and progress of human history. After long-term research, the development context of ancient iron-smelting and steel-making technology has been initially formed, but there is still a gap in the judgment method of the specific smelting and processing technology. The historical records related to iron and steel production are very limited. Therefore, in addition to further excavating the relevant information in ancient books, scientific analysis of the relics unearthed (or out of water) in archaeological excavations is an important means of understandin...
