Abstract:
A method of heating a body of molten aluminum in a container to more efficiently add heat to the molten aluminum, comprising the steps of:(a) providing a container having a body of molten aluminum therein, said body having a surface and said container having a bottom; (b) applying heat to the body; (c) providing a conduit in said body, said conduit having a first portion thereof adjacent said bottom and at least one opening thereinto to permit molten aluminum to flow into said conduit, said conduit having a second portion thereof having at least one opening in said second portion to permit molten aluminum to flow out of said conduit into said body; and (d) introducing gas to said conduit to flow molten aluminum upwardly therein, said molten aluminum flowing into said conduit through said opening in said first portion and out of said conduit through said opening in said second portion, thereby circulating molten aluminum in said container to provide a stirring motion to more efficiently add heat to the body of molten aluminum.
