The vertical–horizontal (VH) rolling process is widely used to perform large width reductions in hot strip mills. The vertical rolling, also referred as edge rolling or slab edging, deforms the slabs in the width direction and gives rise to the "dog bone" slab shape formation. At this stand deformation is mainly localised close to the rolls.Web
