ABSTRACT:
A gas sparging apparatus particularly useful with molten aluminum includes a sparging box having an inlet, an outlet for the metal with a plurality of baffles arranged to alternately project from the top and bottom of the box into the molten metal stream. The bottom of the box also includes a graphite block connected with a manifold structure. The graphite block is gas permeable so that a sparging or cleaning gas may flow through the block into the molten metal stream to purify the metal.
