Method of forming transfer well
First Claim
1. A method of forming a transfer well inside of a vessel for containing molten metal, the vessel having outer walls including side walls and a cavity inside the outer walls for retaining molten metal, the method comprising the steps of:
- (a) placing a form adjacent at least part of one outer wall of the vessel, the form defining a transfer chamber, wherein the transfer chamber has;
(i) a plurality of chamber walls, (ii) a top surface, (iii) an opening in the top surface, (iv) an uptake section in communication with the opening in the top surface, the uptake section configured to receive at least part of a rotor shaft, and having an entrance at its bottom, the entrance configured to at least partially receive a rotor and allow the rotor to rotate, and (v) an outlet above the entrance and in communication with the uptake section;
(b) placing refractory material in the form to create the transfer chamber, wherein vessel outer wall adjacent the transfer well forms one of the plurality of chamber walls; and
(c) leaving an opening beneath the transfer chamber, the opening in communication with the uptake section.

Abstract
The invention relates to a method for forming a transfer chamber inside a cavity of, or next to, a vessel used to retain molten metal. A form is positioned in or next to the vessel, wherein the form defines the transfer chamber. Refractory material is placed into the form, and an opening is left beneath the transfer chamber wherein molten metal can flow into the opening. The transfer chamber is formed such that at least one chamber wall of the transfer chamber is part of at least one outer wall of the vessel, and at least one chamber wall is inside the vessel cavity and is not an outer wall of the vessel. The transfer chamber is formed with an uptake section, a top surface with an opening, and an outlet. The method may also include placing brackets into position and positioning a molten metal pump in the transfer chamber.
