Process and apparatus for producing zirconium metal by reducing zirconium tetrachloride

摘要

The invention relates to a metal Zr manufacturing method by molten Mg in a reactor (1) having a sole (3), in which method separates the magnesium chloride formed in the metal Zr formed and reduction reaction of magnesium, wherein then cooled and extracted the sponge cake of metal Zr formed. This method is characterized in that separating the magnesium chloride formed by tapping to the reactor bottom (1) by means of a chimney (6) whose lower end portion (5) is attached to an orifice (4 ) of the sole (3) and whose cross-high open end (7) is above the portion of metallic mass (Zr, Mg) bordering the chimney (6) at the end of the reduction reaction.; The invention also relates to the corresponding metal zirconium manufacturing device.; The invention provides a simplification of the separation operation of MgCl₂ and optionally formed with a special structure of the fireplace of the invention, an improvement in the extraction operation of the obtained sponge cake.
