FIELD: metallurgy.
SUBSTANCE: method includes heating of stocks of rectangular cross section and their pressing in rollers with a rhombic calibre in the flat position. Prior to pressing they determine extent of shift deformation in the moment of damage of a sample from the same metal as it is tested for twisting, thickness and width of the stock of rectangular section is determined using mathematical dependencies, and in process of stock pressing they regulate extent of deformation of the stock metal shearing.
EFFECT: increased mechanical properties of rhombic profiles and stability of their shape when released from rolls.
