Title: Method and assembly for processing iron-containing material
Inventor: PALIJ GENNADIJ M
IPC: C21B13/14
Filed: 1995-06-01
Granted: 1997-10-20
Abstract: FIELD: ferrous metallurgy. SUBSTANCE: invention relates to liquid-phase iron oxide reduction processes and can be applied to produce steel in blastless process. Essence of invention resides in that, after iron- containing material is smelted in cyclone, iron oxide reduction is effected by way of blowing in reducing agent into surface metal layer moving through flow groove concurrently with melt to be reduced. Slag is continuously withdrawn from its surface through taphole disposed before slag-separation barrier immersed into metal in spaced relation to the bottom for passage of metal into refinement zone where slag is shaped by way of blowing in powder-like materials. Simultaneously movement of slag in countercurrent to boundary metal layer is formed and slag is withdrawn through taphole. Effluent gas from flow groove is directed into cyclone and used for pre-reduction of iron oxides and melting them via stepwise afterburning with oxygen carrying powder- like batch mixture of iron-containing materials and lime. As melt moves in flow groove, intensity of supplying reducing agent and heat for endothermic reactions is lowered. Assembly includes closed-bottom cyclone with gas-withdrawal part in the form of Venturi tube and a bottom hole to tap smelt over which, in side walls, nozzles to introduce effluent gas from flow groove are disposed. At distances 0.5 and 0.75 cyclone height from its bottom, two stacked rows of nozzles to introduce powder-like charge in oxidant flow are mounted, all the nozzles being arranged unidirectionally and tangentially to cyclone side wall. Reduction and refinement zones are made in a common flow groove separated by slag-separation barrier in 50-100 mm spaced relation to bottom for passage of metal. Reduction zone accommodates jets to blow in reducing agent at the level of lower cut of slag- separation barrier. Refinement zone has in its end downtaking bend, on vertical axis of which, jet to introduce slag-forming and alloying materials is installed in the roof, whereas porous plug to blowing in argon-oxygen mixture is installed in the bottom. EFFECT: enhanced efficiency of process. 8 cl, 2 dwg

Abstract: FIELD: medicine technics. SUBSTANCE: invention relates to cavity filters and may be used for endovascular prophylaxis of pulmonary artery thromboembolism. Aim of invention is to create a light-weight, minimum-size cavity filter with resolving catching elements which, when implanted, would avoid postthrombotic disease of lower limbs as well as embolization and transmural migration of the filter into adjacent anatomic regions. Filter consists of endovasal stent made in the form of two elastic stainless-metal coils mounted coaxially at such a distance from one another which allows them to be curled in opposite directions. The coils are interconnected through a plate with arresters on its ends, which is mounted parallel to stent axis. Coils have holes arranged uniformly and circumferentially, through which crisscross catching filaments of resolving material are rigidly passed in direction from one coil to the other.
