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 v?vof all rolls, 1?n respectively are set to be increased clockwise and in compliance with the relationship: v<v<?<v<?<v. 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.4 dwg |
