Cast component including channel and having surface anti-spot element in turn portion of channel, and related removable core and method

A cast component (90) includes a body (101) and a channel (220) defined within the body. The channel includes a first portion (124), a second portion (126), and a turn portion (122) fluidly coupling the first portion (124) and the second portion (126). The turn portion (122) includes a first surface (232) and a second surface (234). A surface anti-spot element (240) passes through the turn portion (122) of the channel, extending from the first surface (232) to the second surface (234) of the turn portion (122). The element divides the channel in the turn portion (122) into a first sub-channel (242) and a second sub-channel (244). The element is formed from an opening in a removable core (180) used during casting including a surface anti-spot opening (200) at the element location, the surface anti-spot opening providing a path for a low density liquid alloy (164) through a core turn portion (182) of the core to reduce surface spot formation of channels (220) in a body (101) of the component. 本发明提供了一种铸造部件(90)，包
