ABSTRACT:
A plant for producing metal powder from metal melts includes a first chamber with a device for converting a melt stream initially into liquid and then solid metal particles in a non-oxidizing atmosphere, a tundish with a closable floor opening that can be mounted on the first chamber and discharged thereinto, and a melt device for filling the tundish with molten metal. The metal melt is continuously protected against oxidation or absorption of gas, the structural height of the plant is reduced and the capacity of the melt device is utilized to a greater degree by enclosing the melt device by a second chamber separated from the first chamber for maintaining a nonoxidizing atmosphere. The second chamber is equipped with at least one lock into which the tundish can be brought and from which it can be removed. The tundish, formed as a transporting vessel, is provided with a cover for maintaining a non-oxidizing atmosphere during transportation and discharge into the first chamber and the second chamber of the melt device is equipped with a drive mechanism for raising the cover for the filling procedure of the tundish.
