CAST COMPONENT INCLUDING PASSAGE HAVING SURFACE ANTI-FRECKLING ELEMENT IN TURN PORTION THEREOF, AND RELATED REMOVABLE CORE AND METHOD

A cast component (90) includes a body (101) and a passage (220) defined within the body. The passage includes a first portion (124), a second portion (126) and a turn portion (122) fluidly coupling the first and second portions (124, 126). The turn portion (122) includes a first surface and a second...

Beschreibung
Zusammenfassung:	A cast component (90) includes a body (101) and a passage (220) defined within the body. The passage includes a first portion (124), a second portion (126) and a turn portion (122) fluidly coupling the first and second portions (124, 126). The turn portion (122) includes a first surface and a second surface (232, 234). A surface anti-freckling element (240) extends through the turn portion (122) of the passage from the first surface (232) to the second surface (234) of the turn portion (122). The element separates the passage in the turn portion (122) into a first sub-passage (242) and a second sub-passage (244). The element is formed by an opening in a removable core (180) used during the casting that includes a surface anti-freckling opening (200) at the location of the element that provides a path for low-density liquid alloy (164) to flow through a core turn portion (182) of the core to reduce surface freckling of the passage (220) in the body (101) of the component.
