Influences of Edge Rolling on Unsteady Deformation of Metal in Roughing Stage of Continuous Hot Strip Rolling

Abstract:

Edge rolling in roughing area of continuous hot strip rolling is a basic method of controlling slab width. Edge rolling will induce dog-bone, width loss and fish tail at head and tail ends of slabs in unsteady deformation zone. A 3D elastic-plastic FEM model for roughing stage of continuous hot strip rolling was established and research on the influences of those technical parameters such as slab width, thickness and reduction of edging roll on unsteady deformation of metal was carried out. The research work provides a scientific basis for the optimization of edge rolling schedule.
