  • Patent number: 6887424
    Abstract: An inline degassing apparatus for removing solid solution gases as well as nonmetallic inclusions from molten metal in a degassing container, to which the molten metal is continuously introduced for degassing operation and from which the degassed molten metal is continuously removed. A rotary diffusing device is arranged in the degassing container for generating bubbles of inert gas diffused into the molten metal, thereby entrapping solid solution gases as well as nonmetallic inclusions into the bubbles, which are then floated and separated. Heaters are provided, which extend, in a cantilever fashion, from a side wall of container at a position adjacent the bottom wall of the container substantially parallel to the bottom wall.
