SYSTEM AND METHOD FOR COMPONENT MAINTENANCE

摘要

Aspects of the invention include a transfer chamber constructed inside of or next to a vessel used to retain and degas molten metal. The transfer chamber is in fluid communication with the vessel so molten metal from the vessel is pulled through the vessel by the pump as it is degassed. This helps maintain a generally constant flow of molten metal through the degassing vessel. Other aspects relate to a system and method for efficiently performing maintenance on components positioned in a vessel.

主权项

1. A system for degassing molten metal, the system comprising:
(a) a vessel, the vessel having an inlet, a cavity and an outlet; (b) one or more degassers in the vessel; (c) a molten metal pump in the vessel; and (d) a fixed-position lifting device attached to one or more of the motor or one of the one or more degassers, wherein the lifting device can vertically lift a component to which it is attached out of the vessel.
