摘要
对LAZ811合金水冷凝固模具与工艺进行了探索,主要包括熔铸工艺分析、水冷模具的结构设计及浇注参数的确定,并制备出了LAZ811合金铸锭.结果表明:真空感应熔炼+氩气保护,合理的水冷模具结构能够使合金快速凝固,有效防止铸锭内部缩孔及缩松的形成,并获得组织细小、拉伸性能优良的镁锂合金材料,并适用于类似合金的生产.
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.
