Advanced continuously cast high strength low alloy steels are often subject to elemental segregation along the billet or slab centerline during casting and cooling. Monitoring macrosegregation is critical before billet or slab rolling and forming, for if elemental segregation is excessive it can lead to structural weakness, including cracking and breaking of rolled and formed products. Hence, by catching macrosegregation before rolling and forming can save substantially in production costs and material handling and product remelting and casting.
