APPARATUS FOR IODIDE REFINING OF ZIRCONIUM Russian patent published in 2005 - IPC

Abstract RU 2261287 C2

FIELD: production of pure zirconium by iodide refining method.

SUBSTANCE: proposed apparatus has retort and cover making it hermetic, current leads, cooling system and mechanism for delivery of iodine to retort. Peripheral screen chambers located inside retort are used for pouring initial material. Trapezium-shaped multi-loop zirconium wire tightened in space between chambers is used for deposition of pure metal on it. Upper and lower horizontal sections of wire loop are secured to metal disks by means of hooks on which electric insulating rings are fitted; length of horizontal sections does not exceed double diameter of finished bar. Wire is stretched by lower metal disk whose mass ratio to initial mass of wire ranges from 2.0 to 3.0.

EFFECT: increased productivity of apparatus; reduced amount of substandard metal.
