Abstract: FIELD: plastic metal working, namely fin forming of articles with single-side periodicity of their contour such as balancing plumbs. SUBSTANCE: method for fin forming of article comprises steps of drawing together shaping members of die set, redistributing metal of deformed strip blank due to its flowing to die cavity with formation of fin between connection ribs of die set. Cavity of die set is restricted by vertical parallel walls, flat base arranged onto lower drive roll and upper shaping member with connection ribs arranged onto upper drive roll. Said upper shaping member enters between vertical walls of lower roll and rolls over lower flat base. Minimum gap between said lower flat base and shaping member is equal to thickness of article S o . Height of connection rib h p  is equal to (0.5-0.75)S o . Apparatus for performing the method includes two drive working rolls. One of said rolls has profile variable along its circle, other roll has constant profile. Apparatus includes entry and outlet guides mounted onto said lower roll. Connection ribs are mounted on upper roll. Constant profile of lower roll is restricted by flat base and vertical walls. Radius of described circle of roll with variable profile and radius R of constant-profile roll are determined with use of formula given in description of invention. EFFECT: enhanced efficiency due to mechanized production of articles with single-side periodicity of contour. 2 cl, 4 dwg

Abstract: FIELD: nonferrous metallurgy. SUBSTANCE: baddeleyite is processed to produce elevated-purity zirconium dioxide suitable in production of optic materials, base plates for integrated circuits, synthetic diamonds, special ceramics, and piezoceramics. In particular, baddeleyite is dissolved in boiling hydrofluoric acid, while simultaneously condensing its vapors and returning condensate into dissolution zone followed by sulfatization of zirconium fluorite solution obtained. The latter operation is carried out by adding zirconium fluorite solution to concentrated sulfuric acid preheated to 200-250 C to produce solid zirconium sulfate, after which hydrofluoric acid vapors are condensed and returned into baddeleyite dissolution process. Zirconium sulfate is converted into corresponding hydroxide which is calcined to form zirconium dioxide. In another embodiment of invention, zirconium hydroxide is produced by adding zirconium sulfate to ammonia water. Zirconium dioxide obtained in conformity with invention with high yield is virtually silicon-free and contains (in wt %): Fe, less than 0.005; Li, 0.001; Al, less than 0.001; Ti, less than 0.001; Th, less than 0.001.
