Description

technical field [0001] The invention belongs to the field of semi-continuous casting of magnesium alloys, and in particular relates to a semi-continuous casting process of magnesium alloys. Background technique [0002] Magnesium alloy is an alloy composed of magnesium as the base material and other elements. Due to the advantages of low density, high specific strength and specific stiffness, magnesium alloy has been widely used in fields such as aerospace, military industry, and automobiles. In recent years, the speed of aerospace and transportation vehicles is getting higher and higher, the power required is increasing, the stability of components is required to be high and reliable, and higher requirements are placed on the stiffness and elastic deformation resistance of magnesium alloys. , while ordinary magnesium alloys have poor mechanical properties and elastic deformation resistance, which cannot meet the needs of lightweight, high-strength, high-elastic modulus m...
