ABSTRACT:
A method and apparatus for blanketing the surface of material, e.g. molten metal contained in an open top vessel, e.g. induction furnace, by establishing a swirling flow of an inert gas having a density greater than air at the top of the vessel. Inert gas exits the swirl flow through an opening in a flow controlling apparatus having an exit opening with a diameter that is smaller than the base diameter of the swirl adjacent the open top vessel.
