Document Type and Number:
WIPO Patent Application WO/2014/185971
Kind Code:
A3
Abstract:
A method of fluxing or degassing a molten metal residing as a bath in a furnace. The bath of molten metal includes a bath surface height and the method provides at least one rotating impeller in the molten metal bath to initiate a flow of the molten metal. The flow in the molten metal results in elevating a portion of the molten metal above the bath surface height where at least one of a fluxing agent and an inert gas is introduced into the elevated portion of the molten metal.
