ABSTRACT:
A bath of molten metal is provided, from which a flow is removed. The flow circulates through an unheated conduit to a selected location remote from the bath, and then back to the bath. A depending conduit portion having a heated valve is provided at the selected location. Operation of the valve allows a predetermined amount of the molten metal to be directed into a casting mold.
