FIELD: metallurgy.
SUBSTANCE: invention relates to metal forming and can be used in making annular molded articles by forging. Article has two convex sections extending from both sides of annular molded article in direction of its axial line and extending in circumferential direction. Circular material is made so that its one half-section is divided in the direction of the axial line relative to the maximum height of the circular material to one side section and the other side section. Straight line passing through the centers of gravity of said lateral areas is inclined at an angle to the axial line of the annular material, which is 7–40°.
EFFECT: result is production of annular molded article, in metal of which dead zones are reduced.
