Abstract

A metal scrap submergence device comprising an open top chamber including walls of a heat resistant material, an inlet positioned in the chamber, an outlet positioned in the base of the chamber, and a ramp adjacent the side wall of the chamber. The device further including a removable vane, an inwardly or outwardly sloped ramp surface, and/or diverter.

First claim

The invention claimed is:

1. A metal scrap submergence device comprising an open top chamber including walls of a heat resistant material, said open top configured to receive metal scrap, an inlet positioned in a base or side wall of the chamber, the inlet configured to receive molten metal and the outlet configured to receive the molten metal after metal scrap has been introduced, an outlet positioned in the base or side wall of the chamber, and a ramp adjacent said side wall of the chamber, the ramp extending into the chamber from the side wall and including a top surface, the top surface of said ramp being one of inwardly sloped toward a center of the chamber and outwardly sloped toward the side wall for influencing molten metal flow, and a diverter overlying said outlet, the diverter comprising a cylindrical body defining a hollow interior, a plurality of passages being formed in said cylindrical body and communicating with said hollow interior, said hollow interior being in fluid communication with the submergence device outlet.

2. The device of claim 1 including a removable vane.

3. The device of claim 2 wherein said vane is spaced above said ramp.

4. The device of claim 2 wherein said vane comprises a rectangular body.

5. The device of claim 2 wherein said vane is suspended from a point external to an interior of the chamber.

6. The device of claim 5 wherein said vane is attached to the chamber via a hook.

7. The device of claim 2 wherein said vane has a length of at least 50% of a height of the chamber.

8. The device of claim 1 wherein said top surface of the ramp is inwardly sloped toward a center of the chamber.

9. The device of claim 1 wherein said top surface of the ramp is outwardly sloped toward the side wall.

10. The device of claim 1 wherein said ramp includes a first end engaging the base and a second end terminating above the base.

11. The device of claim 10 wherein said ramp extends from between greater than 0 and 270° of the chamber circumference.

12. The device of claim 10 wherein said ramp has an inclined slope of between about 5 and 15° between said first and said second end.

13. A molten metal scrap submergence system comprising a vortexing scrap submergence well, said vortexing scrap submergence well including a diverter overlying an outlet of the vortexing scrap submergence well, said diverter comprising a cylindrical body defining a hollow interior, a plurality of passages being formed in said cylindrical body and communicating with said hollow interior, said hollow interior being in fluid communication with the outlet of the vortexing scrap submergence well.

14. The scrap submergence system of claim 13 wherein said diverter further includes a neck configured to mate with said outlet.

15. The scrap submergence system of claim 13 further including sloped inlet regions adjacent said passages.

16. The scrap submergence system of claim 13 wherein said diverter is selectively detachable from the well.
