Abstract
The present invention involves a process for continuously casting a lithium-containing alloy by direct chill with a direct chill coolant and providing a moisture barrier liquid having a flash point higher than about 400.degree. F. to reduce water absorption in the coolant. The process in one aspect includes applying the moisture barrier liquid as a mold parting composition containing less than a varnish-film forming amount of fatty esters, fatty acids, or fatty alcohols. The process is particularly useful in the direct chill casting of aluminum-lithium alloy by direct chill with ethylene glycol coolant.
