For determining the neutral line on the contact zone to distinguish the forward slip zone and backward slip zone on the contact surface between the deformed pieces and the roll; the contact surface was discretized as finite flow line elements to build a novel analytic model to reconstruct the geometry of contact surface. Moreover; the velocity of flow lines on the contact surface along the direction of x-axis was derived by the condition of steady-state incompressible flow; and the function of neutral line was obtained by determining the neutral radius and the neutral angle of the points on the neutral line. In addition; the forward slip coefficient and backward slip coefficient was derived and the relative slip condition of contact surface between the roll and the rolled pieces was determined. Based on these mathematical models the geometry of contact surface and neutral line were drawn up by mathematical software. The validity of the theoretical model was verified by rolling experiments of alloyed bar and the numerical simulation by rigid-plastic FEM software. Compared with the experimental data and simulation results; the prediction error of the mathematical model is acceptable and results from the mathematical model are satisfying. © 2016; Springer-Verlag London;
