ABSTRACT:
The mold is equipped with a casting ring 6 which is formed by clamping together four generally rectilinear wall segments 8 that are, first, arranged like the sides of a picture frame about the rabbet 52 of a rectangular case 10, and then abutted together, sash-like, at their mitered ends 80, to form a ring, the casting surface 9 of which will produce the rectangular cross-sectional outline common to sheet ingot or the like, when molten metal is fed through the ring. The clamping action is produced by a set of screws 94 at the corners 10' of the case, and after the ring 6 is clamped about a pair of spaced, axially opposing lips 54 and 60 on the case and an annular plate 14 thereabove, the plate 14 is clamped to the top of the case, to secure the ring in place and seal the axial ends of the ring against fluid flow thereacross.
