FIELD: steelmaking industry.
SUBSTANCE: invention relates to round calibrated steel workpiece production by drawing. The workpiece is drawn with a 15-25% reduction in a roller die rotating around it, which has three non-driven cylindrical-conical deforming rollers installed around the circumference at an angle of 120° to each other. Deforming rollers are used, the conical part of which has an angle α equal to 4-8°, while the deforming rollers are rotated by a feed angle β which is greater than 16°, and the drawing speed Vdraw is determined from the ratio 
wherein 
is the length of deforming roller cylindrical part, n is the number of roller die revolutions.
EFFECT: workpiece with a gradient ultrafine-grained structure creation.
