A fully transient numerical model of the direct chill casting process is used to examine the influence of metal feeding systems on the fluid flow and macrosegregation of aluminum alloy 7050. It is well established in the literature that increasing the casting speed and billet diameter deepens the sump, resulting in more centerline segregation. Proper design of metal feeding systems can reduce the effects that these process parameters have on the final level of macrosegregation. In this study, the computed composition profiles and flow fields for the steady-state phase of the casting process are presented for varying casting speeds and billet diameters, for both vertical and horizontal inlet nozzle configurations. The use of a combo bag to damp the inlet flow is also examined.
