Abstract

The V-H(vertical-horizontal) rolling process with groove fillet radii of vertical roll R of 30, 50, 80, 110 mm was simulated by explicit dynamic FEM. The influences of groove fillet radii of vertical rolls on cropping and margin deformation of slab were analyzed. The results show that during the first V-H rolling pass, the non-uniform region length of slab head and tail is decreased as the fillet radius is reduced; during the second and third passes, the pass increment of non-uniform region length of slab is decreased as the fillet radius is increased; comparing of the non-uniform region length with V-roll R 30 mm and V-roll R 110 mm, the former is 5.03% less than the later; the deformation degree of stable segment is reduced as the fillet radius is increased.
