Abstract:
Fume dust is prevented when molten metal is poured into a vessel, and water or water mist is sprayed into the vessel or onto the molten metal, creating a reduced level of oxygen concentration of about 12% by volume, preferably about 8% by volume, inside the vessel or at the molten metal surface.
