FIELD: metallurgy.
SUBSTANCE: asymmetric rolling is carried out with a reduction of 80-86% in one pass, while the circumferential speeds of the rolls are set based on the following ratio: V2/V1=4-5, where: V1 is the circumferential speed of the upper work roll, rpm; V2 is the circumferential speed of the lower work roll, rpm. Then symmetrical rolling of the strip is carried out with a total reduction of not more than 86%.
EFFECT: plasticity of the aluminium alloy strip and isotropy of mechanical properties over its entire cross-section are ensured.
