Analysis and improvement measures for vertical fold cracks in casting of 5-series high magnesium alloy flat ingots
The mechanism of vertical fold defects on the surface of aluminum alloy flat ingots during the casting process was introduced,and the trends of vertical fold cracks in ingots of different grades of aluminum alloys during the casting process and when using different filters(tubular filters,plate filters)were obtained.Based on this,the main reasons for fold cracks in the casting process of high magnesium aluminum alloys were analyzed,and through experimental verification,measures to solve the problem of fold cracks in 5-series high magnesium alloys with high crack sensitivity during the casting process were found.These measures are applied in on-site production to effectively prevent the occurrence of fold cracks during the casting process.
