FIELD: process engineering.
SUBSTANCE: invention optimises rolling process at rolling mill with the pair of two first rolls in contact with second rolls supporting said first rolls. Mill rolls feature contour radial characteristic (CVC-profile) asymmetric relative to mean plane described by 3rd- or 5th-order polynomial. Wedging of the second roll supporting the first roll is selected to set optimum rolling conditions by setting second roll radius characteristic corresponding to 3rd - or 5th-order polynomial. Note here that relationship between factors of polynomials of first and second rolls is set by mathematical relationships that allow for, in particular, roll contact length and roll length.
EFFECT: optimised rolling
