Abstract

A fully transient numerical model of the direct chill casting process is used to examine the influence of casting parameters on the macrosegregation of alloy 7050. The casting speed and secondary cooling boundary condition were varied. The secondary cooling was altered by placing a wiper to divert the free-falling water away from the solidified metal surface. Both the casting rate and wiper placement affect the sump depth and shape, and therefore influence the level of macrosegregation, especially at the centerline. The sump depth and level of macrosegregation increased with the casting rate, while placing the wiper nearer the mold could decrease negative centerline segregation.
