Abstract: The key technology and application of vacuum melting in the preparation of high purity metal materials are discussed. Firstly, the definition, characteristics and application fields of high purity metal materials are introduced. Then, the basic principle, classification and characteristics of vacuum melting technology are elaborated. In terms of critical technologies, the technology of vacuum environment control, equipment and process parameter control, slag and liquid separation and purification, refining and purification are discussed, respectively. The application of vacuum melting in the preparation of tungsten, titanium alloy and copper base alloy is introduced. At last, the problems that vacuum melting technology may face in the preparation of specific metals, such as pollution sources, difficulties in the optimization of process parameters and limitations of applicability are deeply analyzed.

Key words: vacuum smelting, high purity metal material, key technology
