SIMULATION OF VERTICAL-HORIZONTAL ROLLING PROCESS DURING WIDTH REDUCTION BY FULL 3-DIMENSIONAL RIGID-PLASTIC FINITE-ELEMENT METHOD

Vertical-horizontal (V-H) rolling is an important process during width reduction in the roughing stand of hot strip mill. A simulation of st eady-state V-H rolling was carried out by the full three-dimensional r igid-plastic finite element method (3D RPFEM), To consider the shear w ork rate and cope with a singular point, an extremely thin array of el ements was attached before the entry of the roll, The slab shape, the spread, the separating force, and the rolling torque calculated were i n good agreement with the experimental values.
