In order to improve the market competitiveness of products and ensure the quality of products, continuous casting is an important part of steelmaking production. The continuous casting mold is the heart of the continuous casting machine. The quality of the mold affects to a considerable extent. The production efficiency of the continuous casting machine, the stability of the continuous casting process and the quality of the continuous casting billet are directly related to steelmaking production and economic benefits. The copper tube of the continuous casting billet mold is the most important component of the billet mold, and it is also a part that needs to be replaced frequently.
During the solidification of the casting blank, the shape of the inner cavity of the mold copper tube and the contraction law during solidification of the embryo shell remain consistent, thereby reducing the thermal resistance of the gap between them. The mold copper tube is a very important part of the continuous casting machine. There must be no flaws or incompleteness. Therefore, the material requirements of the mold copper tube are very strict. There can be neither crystal softening nor plastic deformation.

In continuous casting, low corrosion resistance often occurs, which directly leads to uneven composition and will eventually affect the smelting quality. In or
