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