Downstream Considerations of Fusion Clad Casting
Fusion casting has been commercially available for over 3 years. Although there are many interesting points to casting, there are several downstream considerations such as scalping, preheat and rolling. Quality rolled clad sheet needs to have a consistent clad thickness. Appropriately varying the geometry of the clad layer during the transient portions of casting results in consistent clad thickness from head to butt. Controlling the edge wipe during rolling off does the same from edge to edge. The severity of edge wipe off can be predicted from relative flow stresses at rolling temperatures and guides the choice of alloy combinations.
