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.

The invention relates to a station for transferring a metal melt from a melting furnace into a transport crucible. The station includes a docking chamber, which has a docking opening and is designed to be docked to a filling opening of the transport crucible a suctioning device, which is designed to suction a gas from the docking chamber or from the transport crucible docked to the docking chamber, and a suction pipe, which has a suction channel extending between an inlet opening and an outlet opening. The inlet opening is arranged outside the docking chamber and the outlet opening is arranged in such a way that a metal melt flowing through the suction channel and exiting from the outlet opening passes through the docking opening.

A melt circulating drive device mounted on a side wall of a main bath and driven to agitate nonferrous metal melt present in a melt storage room storing nonferrous metal melt of the main bath. The melt circulating drive device includes a melt drive tank, a melt drive unit, and a partition plate. The melt drive tank includes a hermetically-sealed drive chamber including an opening allowing the drive chamber to communicate with the melt storage room, and the melt drive tank stores melt, which flows from the opening, in the drive chamber. The melt drive unit includes a permanent magnet unit rotated about a first up and down axis while making magnetic lines of force up and down pass through the melt, and a drive unit for the permanent magnet unit that rotates the melt, about the first up and down axis by rotationally driving the permanent magnet unit.

A smart molten metal pump system and method automatically controls the operating speed of the pump rather than requiring an operator to control the speed. The system includes a pump, a controller for controlling the speed of the pump and one or more vibration sensors (such as an accelerometer) to measure vibration. The controller receives input about the vibration of the pump or one or more pump components, and possibly other data, such as the temperature of the molten metal, and/or the depth of the molten metal, ad/or parameters related to the operation of the pump. The controller analyzes the one or more inputs to vary the speed of the pump, turn the pump off, and/or send a communication to an operator.

The invention relates to a device for heating molten metal by the use of a heater that can be immersed into the molten metal. This immersion heater includes an outer cover formed of one or more materials resistant to the molten metal in which the immersion heater is to be used, and a heating element inside of the outer cover, where the heating element is protected from contacting the molten metal.

A pump for pumping molten metal includes a refractory base including at least one inlet, a first outlet, a second outlet, a first volute chamber and a second volute chamber disposed above the first volute chamber. The first volute chamber includes a first volute that is constructed and arranged in a first volute orientation in a top view. The second volute chamber includes a second volute that is constructed and arranged in a second volute orientation opposite to the first volute orientation in a top view. The pump includes a motor driven, refractory shaft and an impeller connected to an end portion of the refractory shaft. The impeller is rotated in the first volute in one rotational direction relative to a top view to direct molten metal through the first outlet. The impeller is vertically moved and rotated in the second volute in an opposite rotational direction relative to a top view to direct molten metal through the second outlet.
