Synopsis : A three-dimensional deformation in slab edge rolling was analyzed using FEM, based on the upper bound theorem and constitutive equation of the meterial with compressibility in plastic deformation, and the effect on the deformation by the strain rate and workhardening characteristics of plasticine was examined. Under various conditions of pass schedule, roll diameter and slab width, edge rolling was analyzed,thus making clear the non-steady slab deformation, and the so-called fish-tail formings at the top and tail of the slab, as well as changes of load, and torque and energy consumption in rolling. |
