ABSTRACT:
An apparatus for making metal powders has a supply tank (2) for the molten starting material, at least one exchangeable pouring funnel (11, 13), at least one atomizing nozzle (12, 14) and at least one fall shaft (7) disposed thereunder for the solidification of the metal powder product. A chamber (1) enveloping the supply tank and the pouring funnel is disposed on the fall shaft (7). To be able more easily to change the pouring funnel or funnels, the chamber (1) has in the area of the pouring funnel a closable lateral opening (15), at which a lock chamber (16) for the introduction of the at least one pouring funnel (11, 13) is placed. A car (24) is held on tracks (18, 19) and can be driven into the chamber (1) and fully retracted into the lock chamber (16), and on its bottom is fastened a number of atomizing nozzles (12, 14) corresponding to the number of the pouring funnels (11, 13). The pouring funnels (11, 13) can be set downwardly onto the cars. The fall shaft (7) is provided with a coupling device (50) which, when the coaxial component group including a pouring funnel (11, 13) and atomizing nozzle (12, 14) has been positioned over the fall shaft (7), produces a gas-tight connection between the fall shaft (7) and the atomizing nozzle (12, 14).
