Abstract
Lithium feed to an aluminum-lithium alloy production system is achieved at a highly controlled rate by advancing a plunger at a predetermined volumetric rate into a body of molten lithium retained in a holding vessel to displace the lithium toward an overflow port through which it is fed into a mixing vessel where it is combined with molten aluminum. Control of the aluminum feed rate is achieved by maintaining a constant head height upstream of an orifice. The thus metered streams of molten lithium and aluminum are then combined in a vortex bowl, whose outlet is then fed to a casting station.
