Research on productive technology of 8006 aluminum alloy super-large flat ingot
In the production of 640 mm×2 400 mm super-large flat ingots of 8006 alumi-num alloy,the purity of the melt is difficult to control and the casting process is exceptionally sensitive to changes of water temperature,resulting in difficulties in forming.Measures were taken to ensure the purity of the melt from three aspects:raw materials,melt refinement,on-line filtration,and the casting parameters were determined by experiments.Then testing on melt purity,appearance and internal structure of flat ingots indicate that the measures can ef-fectively control the slag content of the melt and ensure smooth formation of the ingot.
