DEVICE FOR RECEIVING OF TANTALUM POWDER OF CONDENSING TYPE Russian patent published in 2010 - IPC B22F9/22 F27B7/04 C22B34/24 

FIELD: metallurgy.

SUBSTANCE: invention elates to metallurgical field, particularly to device for receiving of tantalum powder of condensing grade by magnesium-thermal recovery. Device contains heated rotating tubular reactor with rotating drive and magnesium evaporator. Reactor allows on inner surface of rib. Additionally evaporator and reactor are implemented in the form of sections of united horizontally located block, divided to each other by partition with central opening and are placed into waterproof vessel. Additionally vessel is outfitted by thermal shield, located from the side of input of rotating drive and is heated by furnace with zonal heating.

EFFECT: there is provided consistent regeneration and increasing of evaporating surface of magnesium and prevention of formation in it of oxide, evaporation rate enhancing of magnesium, more efficient usage of evaporator volume.
