ABSTRACT:
The system includes: (a) a hollow cylindrical body adapted to be mounted in a casting table, (b) an annular water baffle removably mounted in the body, the baffle having a central opening through which a forming ingot passes and the baffle providing a flow path for cooling water to flow radially inwardly from the body and discharge inwardly and downwardly against a forming ingot passing through the central opening, (c) an annular mould removably mounted in the body immediately above the water baffle having a central forming cavity for forming a metal ingot, the forming cavity having a smaller diameter than the central opening of the water baffle, (d) a feed inlet for molten metal comprising an insulating ring removably mounted within the body immediately above the mould, the outer diameter of the insulating ring being less than the diameter of the body, (e) a pressure ring removably mounted in the body in the annular gap between the body and the outer diameter of the insulating ring, and (f) a cover plate adapted to compress the components of the mould system together. The annular members are selectively replaced with ones of variable inner diameter or length depending upon the diameter of ingot desired and the composition of the metal being cast.
