Abstract: The rolling process of shape slab is simulated numerically by rigid-plastic finite element method (R. P. FEM). The constraint relationship between velocity components of nodal points on the side sloping contact face is discussed. The spread at side edges, the metal filled degree at ribs, separating force and rolling torque are obtained and in a good agreement with the experimental ones. And the distributions of equivalent strain-rate and metal flow are also calculated.
