【Abstract】 The LAZ811 water-cooled solidification mold and process were explored, mainly including the analysis of the melting and casting process, the structural design of the water-cooled mold and the determination of casting parameters, and the preparation of LAZ811 alloy ingots. The results showed that vacuum induction melting+argon protection and reasonable water-cooled mold structure could make the alloy solidify rapidly,effectively prevent the formation of internal shrinkage and shrinkage loosening of the ingots, and obtain the magnesium-lithium alloy material with fine organization and excellent tensile properties, which is suitable for the production of similar alloys.更多还原
