Abstract
A material scrap submergence device comprises a body (10) of heat resistant and/or a refractory material that includes a side wall (12) and a base (14) that define a submergence chamber (10). The refractory body (10) can include passages (24) that receive rods (22). The rods (22) can place the refractory body (10) under compression. In another embodiment, the body is confined by a frame (72) attached to the body. The submergence chamber (10) can also be used as a gas injection chamber.
Claims18
A scrap submergence device comprising:
- a body defining a submergence chamber comprised of a refractory material, wherein said body comprises a side wall and a base, the side wall including an at least substantially vertically oriented passage, and the base including an at least substantially vertically oriented passage aligned with the passage in the side wall, at least one linearly upward sloped inlet channel and one discharge channel;
- a frame member surrounding a portion of said sidewall remote from said base, the frame further including a flange positioned adjacent a top edge of said submergence chamber, said flange including an opening aligned with said vertically oriented passage;
- a rod in the at least one passage, wherein the rod extends through the flange opening the at least one side wall passage and the at least one base passage,
- wherein said rod is placed under tension to impart a compressive load on the body and secure said frame to the body.

A metal scrap submergence device comprising:
- a body comprising a side wall and a base, the side wall including an at least substantially vertically oriented passage, and the base including an at least substantially vertically oriented passage aligned with the passage in the side wall;
- a frame surrounding at least an upper portion of said body, the frame including a flange having at least one hole aligned with said passage in the side wall;
- a rod received in both of the passages and the hole in the flange securing said side wall to said base;
- an inlet passage disposed in the base for allowing molten material to enter the scrap submergence device;
- and
- an outlet passage disposed in the base for allowing molten material to exit the scrap submergence device,
- wherein said inlet passage is substantially tangential to said side wall creating a vortex flow of molten metal.
