METHOD OF STRAIGHTENING ROLLED PLATES Russian patent published in 2016 - IPC B21D1/06 

Abstract RU 2581697 C1

FIELD: metallurgy.

SUBSTANCE: invention relates to production of rolled sheet at reversing plate mill, and can be used to provide flatness of rolled low-alloy expected steels. Straightening is performed with maximum flexure at first bending roller in direction of movement of rolled stock with certain amplitude of maximum flexure at straightening temperature of above and below 150 °C. Amplitude of bending at the second bending roller is set not over 0.7 of maximum amplitude curve at first roll and amplitude curve at last bending roller is set not over 0.25 of rolling thickness.

EFFECT: requirement is met for flatness of finished products.
