Abstract
In a method of preventing contact of oxygen with a metal melt, metal melt flows into a casting chamber bounded by walls ( ) and leaves this chamber as a stream. In order to completely prevent contact of oxygen with a metal melt and thus reoxidation, oxygen attempting to enter via any gaps ( ) between the walls ( ) and/or adhering to the walls ( ) is reacted to form a compound which is not injurious to the metal melt ( ).
