Abstract
A device for discharging molten metal from a container to another, comprising an outlet sleeve which penetrates into the lower container pushed by springs against a nozzle of refractory material which connects the inside of the upper container with the outside, so as to make a seal for the molten metal. The outlet sleeve is surrounded by a cylindrical sheath which joins, through a sand joint with a cylindrical blade fixed to the base of the upper container, around the aperture where it faces the nozzle. The sheath and the blade enclose a volume into which an inert gas is injected to remove the air possibly present.
