METHOD OF ROLLING OF STRIPS IN VERTICAL ROLLS OF STRIP MILL Russian patent published in 2015 - IPC B21B1/22 

FIELD: metallurgy.

SUBSTANCE: method includes crimping of strip in vertical rolls after passes in horizontal rolls. Rolling in vertical rolls of a strip mill is performed at hot and cold rolling with relative crimping the limit size of which depends on the ratio of strip thickness to width h_i/b_i after i-th pass in horizontal rolls and the module of elasticity of the material of strip E for wide dimensional and branded range of roll stock.

EFFECT: reduction of variability of strip width without violation of their stability when rolling.
