FIELD: metallurgy, production of secondary aluminum alloys. SUBSTANCE: aim is to simplify process and to decrease costs. Heating chamber is loaded with slags of silumins production and synthetic silumins. Produced two layer bath is introduced with scrap and wastes of aluminum with iron parts and held under temperature of 700 - 720 C for 20 - 30 minutes. Then metal is poured out and cycle is repeated. Method allows to simplify process and to decrease by 8 - 10 % costs of charge unit processing. EFFECT: simplified process, decreased costs. 4 cl
