Molten metal transfer system and rotor

摘要

The invention relates to systems for transferring molten metal from one structure to another. Aspects of the invention include a transfer chamber constructed inside of or next to a vessel used to retain molten metal. The transfer chamber is in fluid communication with the vessel so molten metal from the vessel can enter the transfer chamber. A powered device, which may be inside of the transfer chamber, moves molten metal upward and out of the transfer chamber and preferably into a structure outside of the vessel, such as another vessel or a launder.

主权项

1. A rotor with blades for directing molten metal towards the rotor interior and away from the rotor interior, wherein each rotor blade comprises:
(a) a first portion having first upper surface angled to direct molten metal upwards; (b) a second portion separate from, directly juxtaposed to, and at least partially above the first portion, and having a second upper surface angled to direct molten metal upwards; and (c) a third portion separate from, juxtaposed to, and at least partially above the second portion, and having at least one outwardly-projecting surface.
