Determination of sliding zone sizes in varying deformation core at axisymmetric rolling

Method to determine sizes of sliding zones at both the deformation core filling by metal, and after it, is proposed. Constructive peculiarities of the longitudinal rolling-mill operating stands, simultaneous influence of different loading asymmetry sources, initial ratio of strip and roll velocities, inertial properties of strip and moved masses of rolling-mill main line elements, are taken into account.
