ABSTRACT:
An apparatus for producing directionally solidified castings wherein a mold having an open bottom is supported on a chill plate with metal poured into the mold initially solidifying adjacent the chill plate and thereafter progressively solidifying away from the chill plate. The chill plate is provided with a plug member, and the metal being cast initially solidifies around this plug member whereby the metal is securely held in intimate contact with the plug member and adjacent chill plate surfaces so that the withdrawal of heat from the casting through the chill plate is greatly facilitated.
