FIELD: metallurgy. ^ SUBSTANCE: invention can be used for melts refinement from aluminium alloys in preference high-alloy. Method of aluminium alloys vacuum treatment includes pouring of heated melt into furnace, creation of vacuum in furnace, melt isolation in vacuum during 4590 minutes in the range of temperatures higher liquidus point for 1530C at residual pressure 1.33ù10218.62ù102 Pa. ^ EFFECT: reduction of being duration of molten metal in holding furnace, keeping of modifying agent effect, receiving of uniform fine-grained structure and reduction of hydrogen content in casting ingots, reduction of defects amount in manufactured deformed semi-finished products. ^ 2 cl, 1 tbl, 2 ex |
