Theory and experimental research on the process of rolling shape slab

The rolling process of shape slab is simulated numerically by the rigid–plastic finite element method (RPFEM). The constraint relationship between velocity components of nodal points on the side sloping interface is discussed. The spread at side edges, the metal filled degree at ribs, separating force and rolling torque are obtained and found to be in good agreement with experimental values and the distributions of equivalent strain rate and metal flow are also calculated.
