Description
Technical Field
The utility model relates to a concise preparation high-purity nitrogen gas device of metal magnesium, specifically speaking are a high-purity nitrogen gas device that is used for concise preparation of metal magnesium belongs to the concise device field of magnesium.
Background
Magnesium is a light, ductile, silvery white metal. The composite material has rich reserves, excellent performance and wide application prospect, and is widely applied to the fields of military industry, aerospace, traffic, 3C and the like. The production process of magnesium includes a thermal reduction method and an electrolytic method. The magnesium produced by electrolysis or reduction is referred to as crude magnesium. Crude magnesium, which conventionally contains certain impurities, must be refined to meet the requirements. These impurities in magnesium have a large influence on the properties of magnesium. The refining method of the crude magnesium comprises a flux refining method, a sublimation refining method, a thermal reduction refining method, a zone melting refining method and an electrolytic refining method. During the refining process, protective gas is usually required to be introduced to avoid the magnesium from contacting with air and prevent the magnesium from burning.
