Abstract: A device for metering and transferring liquid metals. It includes a supporting structure and, a hollow sleeve on the supporting structure open at both ends. A pouring spout is on one end and has an orifice therethrough communicating with the hollow interior of the sleeve. A stopper rod extends into the sleeve from the other end thereof to be shiftable between a position seating on the pouring spout and sealing the orifice therein at a position removed from the pouring spout to permit liquid metal to flow into and out of the sleeve. At least a portion of the stopper rod which seats on the pouring spout and the portion of the pouring spout in engagement with the stopper rod are formed of graphite material. Other portions of the device are formed of a ni-resist alloy with a layer of oxide formed on those surfaces of the ni-resist alloy which are brought into contact with the liquid metal to increase the chemical resistance of those surfaces to the liquid metal being metered and transferred.

Abstract: A device for metering and transferring liquid metals. It includes a supporting structure and a hollow sleeve open at both ends on the supporting structure. A pouring spout is on one end of the sleeve and has a passageway therethrough communicating with the hollow interior of sleeve. A stopper rod extends into the hollow sleeve from the other end thereof to be shiftable between a position seating on the pouring spout and sealing the passageway therethrough and a position removed from the pouring spout to permit liquid metal to flow into and out of the sleeve. The stopper rod is shiftable between positions and the pouring spout includes a bushing mounted in the passageway and having a threaded opening therethrough and a threaded plug interengaged with the threaded bushing and having an orifice therein to provide for communication between the interior and the exterior of the sleeve through the pouring spout.
