METHOD OF PRODUCING A THIN STRIP Russian patent published in 2019 - IPC B21B1/22 

FIELD: metallurgy.

SUBSTANCE: invention relates to metal forming. Rolling of thin strip is carried out in two working rolls with mismatch of their speeds. Increase in the strip deformation stability and reduction in the rolling force is ensured by the fact that rolling is performed with mismatch of speeds at least twice with single degree of deformation of not less than 50 % to total deformation degree of 75–95 %. At that, rolling is performed with front and rear tension, wherein rear specific tension is set equal to 0.10– 0.20 of yield point, and front specific tension is specified by mathematical relationships.

EFFECT: method of producing a thin strip is disclosed.
