The mould comprises a backing frame (3) and an assembly of individual mould wall plates defining the casting cavity. A mould wall plate (7) comprises two complementary parts (8, 9) one of which (8) affords a surface (11) of the casting cavity (F) whilst the other (9) is shaped to mate with the frame (3). The parts (8,9) mate along an interface (10) at which coolant-conducting passages (13) are provided. Seals (16) may be provided at the interface (10) or a copper foil may be provided between the two parts (8, 9), especially if these are of different materials e.g. copper and steel. <IMAGE> |
