Molten metal transfer vessel and method of construction
First Claim
1. A method of forming a transfer well inside of a vessel designed to contain molten metal, the vessel having a first side wall and a second side wall, wherein the first side wall and second side wall are spaced apart from each other, a first end wall at a first end of the vessel, the first end wall extending between the first side wall and the second side wall, a second end wall positioned at a second end of the vessel, the second end wall extending between the first side wall and the second side wall, wherein each of the first side wall, second side wall, first end wall, and second end wall, has an inner surface, the vessel further including a bottom surface and a cavity defined by the first side wall, second side wall, first end wall, second end wall, and the bottom surface;
- the method comprising the steps of;
(a) placing a form adjacent at least one inner surface, the form having a first structure, a second structure, and a space between the first structure and second structure, the form defining a transfer well having an outer wall, a top surface, a bottom surface, an open top, and an internal cavity;
the internal cavity shaped to have a lowermost section, and an uptake section above the lowermost section, wherein the lowermost section is narrower than the uptake section, the uptake section in communication with the open top; and
an outlet in communication with the uptake section;
(b) placing refractory material in the space to create the transfer well, wherein the side of the vessel adjacent the transfer well forms a side of the of the transfer well; and
(c) providing a molten metal pumping device for the transfer well, wherein the molten metal pumping device has a rotor, a motor, and a drive shaft connecting the rotor to the motor, and;
(i) the rotor has a width that is 1″
or less than the width of the lowermost section, and (ii) the length of the drive shaft is sufficient for the rotor to be received in the lowermost section while the motor is above the open top.

Abstract
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.
