FIELD: metallurgy.
SUBSTANCE: procedure consists in degreasing chips with water solution of detergent implementing ultra-sonic bath, in washing chips in hot water, in their drying and crumbling. Also before degreasing chips are crumbled and simultaneously sprinkled with water solution of detergent; degreasing is performed in the ultra-sonic bath where concentration of detergent is 10-40 g/l at temperature 50-65°C during 5-10 minutes. Upon sizing and/or magnet separation chips can be introduced into composition of alloys as addition to charge materials.
EFFECT: increased quality of metal produced out of metal chips, and its reduced prime cost.
