Process for purging aluminum and aluminum alloy melts of small quantities of alkali and alkaline earth metals |
摘要 |
Small quantities of alkali metal and alkaline earth metal impurities are removed from an aluminum melt by introducing a source of sulfur such as elemental sulfur, which combines with the impurity to form an impurity-containing slag, purging the melt with gas to remove excess sulfur, and separating the purified melt from the slag.
