Method for continuous casting of an aluminum-lithium alloy

摘要

In a method for continuous casting of an aluminum-lithium alloy through an open-ended mold for forming an ingot, wherein gas under pressure is brought into contact with a molten surface part of said ingot directly before solidification, the gas used consists of from 1 to 15 volume % of oxygen and balance of inert gas. The casting is stabilized and cast skin is improved by the use of said gas.
