Inline degassing apparatus
First Claim
1. An inline degassing apparatus for a continuous flow of nonferrous molten metal, said apparatus comprising:
- an inline degassing container having a side wall and a bottom wall for defining a chamber for storing therein nonferrous molten metal;
an inlet provided on one side of the container for receiving said continuous flow of the nonferrous molten metal into said container for a degassing treatment of the material in the container;
an outlet provided on the other side of the container for discharging the continuous degassed flow of the nonferrous molten material from the container;
a rotary gas diffusing device for inert gas provided in the container, the rotating movement of the rotary gas diffusing device generating bubbles of inert gas diffused into the nonferrous molten metal stored in the container for removing continuously solid solution gas or nonmetallic inclusions from the nonferrous molten material in the containers;
at least one heater extending from said side wall of said container at a location adjacent the bottom wall substantially parallel with respect to said bottom wall of the container, said at least one heater being configured to be substantially entirely located in the molten metal stored in said container; and
a plurality of baffle plates extending substantially vertically along an inner surface of said side wall of said degassing container, said at least one heater being located substantially under the gas diffusing device, which is surrounded by the baffle plates.

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.
