METHOD FOR ASYMMETRIC ROLLING OF COLD-ROLLED STRIP MADE OF ALUMINIUM ALLOY AMg6 Russian patent published in 2023 - IPC B21B1/22 B21B3/00 B21B37/46

Abstract RU 2793650 C1

FIELD: metal processing by pressure.

SUBSTANCE: cold rolling of AMg6 aluminium alloy strip. Rolling is carried out in two rolls with a mismatch of their circumferential speeds in one pass with reduction ɛ=8-65%. The circumferential speed of the upper roll is set equal to V₁=1.9-2.1 rpm. The circumferential speed of the lower roll is set equal to V₂=5V₁ rpm.

EFFECT: strip of aluminium alloy AMg6 with reduced hardness is obtained.
