Molten metal transfer system and method

A method of adding positioning a free-standing, transportable molten metal transfer device into a vessel cavity, the method comprising the steps of:

• (a) lifting and moving a free-standing, transportable transfer device into the vessel cavity, wherein the free-standing, transportable transfer device is not constructed as part of the vessel and comprises a housing having a top, a first side, a second side, a third side, a fourth side, an enclosed bottom, an outer surface, an uptake section in the housing, wherein the uptake section is open and configured so molten metal can be moved upwards into the uptake section;
• a rectangular outlet in one of the first side, the second side, the third side, and the fourth side, wherein the rectangular outlet is in fluid communication with the uptake section;
• and an inlet in either the first side, the second side, the third side, or the fourth side, wherein the inlet is beneath the rectangular outlet and is in fluid communication with the uptake section;
• and
• (b) positioning a molten metal pump at least partially into the uptake section of the free-standing, transportable device such that a rotor and at least part of a drive shaft of the molten metal pump are positioned in the uptake section and a motor of the pump is above the rectangular outlet and outside of the uptake section, wherein as the drive shaft and rotor rotate molten metal entering the uptake section through the inlet is moved upwards and exits the rectangular outlet.
