Abstract
A molten metal transfer device for withdrawing a selected quantity of molten metal from a bath includes structure defining a chamber disposed within the bath, the chamber including a first opening through which molten metal can flow from the bath into the chamber and a second opening through which molten metal can flow outwardly from the chamber. A cup-like bucket is disposed within the chamber for vertical reciprocating movement, the bucket having a generally vertically oriented slot included as part of its sidewall. The device includes a displacement mechanism for urging the bucket laterally toward engagement with the surface of the chamber. The device also includes mechanisms for easily removing buckets and chambers and replacing them with new buckets and chambers.
