Abstract
A metal scrap submergence device having an open top chamber including side and base walls of a heat resistant material. An inlet is included in a side or base wall of the chamber for receiving molten metal. An outlet is included in the base of the chamber. A ramp extends from the side wall of the chamber to an inner column defining the outlet. The ramp includes a first edge adjacent the side wall and second interior edge adjacent the inner column. The working surface of the ramp between the first and second edges is concave. The inner column includes an end wall disposed opposite the chamber base, the end wall includes rounded inner and outer edges.
