Abstract

Treating liq. metals with solid addns., in which the liq. metal is poured into a ladle which already contains the product which is housed in an independent compartment which communicates with the interior of the ladle through its lower part only. After filling the compartment with the prod., it is sealed by a cover. liq. metal is poured into the ladle so that it rises into the compartment and the gases or vapours given off by the reaction are formed constantly in the compartment and exhausted by bubbing at the bottom of the ladle and passing through the liq. metal.
