ABSTRACT:
A method and apparatus for the quiescent-fill dip of a foundry ladle and the transportation of molten material from a crucible to a mold through a foundry pour basin. Advantages from this process include, among others, a design which minimizes or eliminates turbulence in the molten material, especially in regard to the folding of one stream of molten material into another, as a means to provide undamaged metal to casting molds.
