A device includes a molten metal pump and a metal-transfer conduit. A clamp may be used to attach the metal-transfer conduit to the pump. The pump has a pump base including an indentation configured to receive the metal-transfer conduit and align the pump outlet with the transfer inlet. The pump outlet may be formed in the indentation and preferably near the center of the indentation in order to better align with the transfer inlet. As the pump operates it moves molten metal through a pump outlet that is in communication with a transfer inlet in the metal-transfer conduit. The molten metal enters the transfer inlet, moves upwards in a passage in the metal-transfer conduit, and out of a transfer outlet.

A melt transport device includes a melt container, in which a melt receiving space is formed, and a spout, which is coupled to the melt container, wherein the spout includes a spout orifice which is flow-connected to the melt receiving space. Moreover, a gas valve is formed, which is flow-connected to the melt receiving space and which is configured for regulating the introduction of gas into the melt receiving space.

A molten metal mixing system capable of controlling generation of oxides in mixing of molten metals to. The system includes 1st/2nd apparatus for melting 1st/2nd raw materials into 1st/2nd molten metals, and a pipe connecting the 1st and 2nd apparatus. The 2nd molten metal produced in the 2nd apparatus is transferred through the pipe to the 1st apparatus to mix with the 1st raw material and/or the 1st molten metal. The 2nd apparatus has a tapping chamber for retaining the 2nd molten metal to be transferred to the 1st apparatus. The 1st apparatus has a receiving chamber for retaining the 2nd molten metal transferred from the 2nd apparatus. When part of the 2nd molten metal is discharged out of the receiving chamber to lower the surface of the molten metal, the 2nd molten metal in the tapping chamber is transferred through the pipe into the receiving chamber by siphon principle.
