FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy industry. Aggregate contains two driven rollers, installed over the metallic reservoir. Rollers allows cylindrical and tapering sections, partly located in metallic reservoir. During the rotation of rollers on cylindrical sections there are crystallised metal layers, which then are subject to plastic deformation. Metallic reservoir is installed as rotary by drive relative to axis, parallel to rollers axis. During the rotation of metallic reservoir its volume is reduced ensured by changing of fettling thickness.
EFFECT: it is provided process simplification and productivity improvement.
