An discharging device for molten metal between an upper ladle (1) and a tundish (3) comprising a slide valve nozzle fixed to the base of the ladle, comprising an upper fixed nozzle (42) and a mobile one below (43), inserted into an opening in the base of said slide valve nozzle with the lower end protruding from it, and a ring shaped blade (46) fixed to the base of the slide valve nozzle around said aperture. The tundish (3) comprises a cylindrical jacket (22) placed with a vertical axis and fitted at its end with a sand joint (24) for sealing gas into which the ring shaped blade is sunk (46). The slide valve nozzle can be fixed to the base of the ladle by mountings (48, 49) fitted with eyelets into which pivots (50) are inserted.
Molten metal discharging device between a first upper container (1) and a second lower container (3), the device comprising a slide valve nozzle comprising an upper (42) and a lower (43) nozzle, the lower nozzle being movable with respect to the upper one, a circular blade (46), fixed to the base of the slide valve nozzle around a molten metal discharging aperture, said lower nozzle being inserted into said aperture with the lower end protruding from it, the discharging device comprising also a cylindrical jacket (22) defining a vertical axis and having at its upper end gas sealing means (24) adapted to be coupled to said circular blade (46) and adapted to surround the lower end of the lower nozzle (43) in operation, said cylindrical jacket (22) being fixed above said second container.
