FIELD: technological processes.
SUBSTANCE: invention relates to methods for rolling a preform in the form of a ring. Rolled workpiece is made by roller tools. First, a regular microrelief of the surface is formed by the roller tool due to the microrelief on its working surface, and then smooth the surface of the microrelief by pressing it into the surface layer of the material with a roller tool with a smooth working surface.
EFFECT: as a result, the operating characteristics of the rolled ring are increased.
