ASYMMETRIC METAL ROLLING Russian patent published in 2014 - IPC B21B1/00 

FIELD: metallurgy.

SUBSTANCE: proposed method comprises rolling with mismatch of rolls speed at three-roll gage. Better processing of metal at higher shear strain is ensured owing to peripheral speeds v₁…v_n of all rolls, 1…n respectively are set to be increased clockwise and in compliance with the relationship: v₁<v₂<…<v_i<…<v_n. At rolling, metal surface sections in contact with rolls of lower speed are decelerated to down the metal rolling-out. Sections in contact with rolls of higher peripheral speed are accelerated for metal larger rolling-out.

EFFECT: irregular distribution of rolling-out over strained blank cross-section.
