ABSTRACT:
A fluid cooled shot sleeve assembly for transferring molten metals. The shot sleeve is of a three layer construction in which a copper intermediate layer is attached to the outside surface of an inner metal charging chamber. A high strength outer jacket is fitted onto the copper intermediate layer and serves to hold the inner metal charging chamber straight until excessive heat buildup in the charging chamber is dissipated by the copper layer. A heat transfer conduit of semi-circular design is located within the wall of the metal charging chamber and in contact with the intermediate copper insert. This conduit permits a heat transfer fluid such as water to cool both the inner steel charging chamber which is in contact with the molten metal and lower the temperature of the copper layer to increase its ability to transfer heat from the metal charging chamber.
