A transfer pump system has a pump base with a pump chamber, tangential discharge and an outlet. A riser tube extends from the outlet and terminates at a launder in order to move molten metal out of a vessel with relatively little turbulence. A riser tube for use in the system has a proximal end configured to be connected to the outlet and a distal end that terminates at or above the launder.

A transportable vessel for use in transporting molten metal, wherein the transportable vessel is not part of a reverbatory furnace and can be moved to different locations. The vessel includes a transfer conduit in communication with a cavity of the vessel. A molten metal pump can be positioned in the transfer conduit to move molten metal out of an outlet, where the molten metal can move into another structure without the need to tip or tilt the transportable vessel.

Techniques are disclosed for reducing macrosegregation in cast metals. Techniques include providing an eductor nozzle capable of increasing mixing in the fluid region of an ingot being cast. Techniques also include providing a non-contacting flow control device to mix and/or apply pressure to the molten metal that is being introduced to the mold cavity. The non-contacting flow control device can be permanent magnet or electromagnet based. Techniques additionally can include actively cooling and mixing the molten metal before introducing the molten metal to the mold cavity.

A method for quickly finding robust operating points of a casting process is disclosed. Metamodels and extrapolatable models contribute to reducing the experimental effort both in simulation and for practical experiments, and these models are subsequently used for autonomous control of the casting process.

A casting system includes a casting surface; a rim area disposed on the casting surface or associated therewith; a heat resistant impermeable diaphragm having an edge area. The diaphragm covers a portion of the casting mold when it is positioned on the surface so as to form a space defined by at least a base constituted by the surface, and at least a casting face constituted, at least partially, by the diaphragm; a sealing arrangement for sealingly engaging the rim and edge areas, thereby sealing the space; an outlet for withdrawing gas from the space; a heat resistance coefficient of the diaphragm is such that it can melt when coming in contact with the molten material. The diaphragm covers an area larger than that through which molten material is case so that, when the space is sealed, vacuum application causes the diaphragm to adhere to a portion of the mold.

To provide a device and a method for detecting, before pouring starts, any misalignment between a cope and a drag that have been molded by a flaskless molding machine and then assembled. The device (40) that can detect any misalignment between the cope (2) and the drag (3) that have been molded by the flaskless molding machine (1) and then assembled and that are being transported to the position for pouring comprises a plurality of means (51), (52), (53) for measuring distances to the cope and the drag that measures the distances (S11), (S12), (S13), (S21), (S22), (S23) to the cope and the drag, and a means (48) for calculating a degree of a misalignment between the cope and the drag on a basis of the distances to the cope and the drag that have been measured by the means for measuring distances to the cope and the drag.
