Production of aluminum-lithium alloy by continuous addition of lithium to molten aluminum stream

摘要

A continuous process for forming aluminum-lithium alloys is disclosed which comprises continuously monitoring the ingot casting rate and continuously adding a measured and controlled amount of molten lithium beneath the surface of a molten aluminum stream as it flows toward an ingot casting station. The amount of molten lithium to be added is based on the ingot casting rate, the ingot size and the lithium content of the alloy being cast.
