摘要： A cooling liquid is injected into and supplied to a cooling tubular body along its inner periphery to form a cooling liquid layer flowing down the inner peripheral surface of the body while revolving. A molten metal is then injected into the cooling liquid layer from the inner peripheral side thereof to divide, rapidly cool and solidify the stream of molten metal with the cooling liquid layer and obtain a metal powder. Since the metal powder is continuously obtained upon flowing down the tubular body along with the cooling liquid, the liquid can be continuously removed from the powder by suitable means, and the power can be subsequently dried continuously.

摘要： A melt overflow apparatus for controlling various elements in response to incremental changes in parameters which affect the linear density of a continuous metal fiber mat or metal strip being produced is described. The net width of fibers being cast against a rotating, cylindrical casting wheel is measured by an infrared detector. A similar infrared detector is used to measure the net width of a metal strip being formed against a casting wheel. The weight of a portion of the strip or fiber mat is also measured. The weight and net width values are relayed to a control system which then controls various elements used in producing the metal product. These devices include electric motors driving both the casting wheel and a conveyer means for transporting the fiber mat or strip. A ceramic plunging body driven into a pool of molten metal to overflow onto the casting wheel can also be controlled.

摘要： A method and apparatus for making metal flakes from a body or stream of molten metal. The apparatus includes a wheel with serrations on its periphery, and means for rotating the wheel in a vertical plane. Means are provided for controlling the relative positions of the wheel and the upper surface of the body of molten metal which is subjected to change. In this manner, the serrations on the bottom of the wheel are disposed a preselected distance into the body of molten metal. When the serrations rotate out of the body, molten metal collects on the serrations and freezes into solid flakes. Means are provided for removing the flakes from the serrations and for collecting the flakes at one location on the periphery of the wheel.

摘要： A method is disclosed for producing a rare earth metal-transition metal-boron (R-T-B) bonded magnet with a magnetic anisotropy. R-T-B alloy ribbons and/or ribbon-like flakes containing R.sub.2 T.sub.14 B fine crystals are prepared with a thickness of 20-1,000 .mu.m by rapidly-quenching method. The ribbons and/or flakes are crushed and ground into a magnetic powder of particle sizes smaller than the value of the ribbon thickness. The magnetic powder is mixed with binder agent and formed into desired bulk-shape body in an aligning magnetic field to produce the bonded magnet with the magnetic anisotropy. In order to improve the magnetic properties, the ribbons and/or flakes can be heat-treated at a temperature of 650.degree.-950.degree. C. The magnetic powder can also be teat-treated at a temperature of 500.degree.-700.degree. C.

摘要： In a method for producing a rare earth metal-iron-boron (R-Fe-B) anisotropic sintered magnet from R-Fe-B alloy ribbon-like flakes, each flake is formed with a thickness of about 20-500 .mu.m and contains R.sub.2 Fe.sub.14 B crystal grains dispersed in the flake with an average grain size of 10 .mu.m or less. The flakes are ground into a powder having an average particle size less than the thickness value of the flake. The powder is magnetically aligned and compacted into a compact body which is then sintered. Thus, the anisotropic sintered magnet is obtained with a high energy product and a high anti-corrosion property. The ribbon-like flakes are prepared by the continuous splat-quenching method. Alternatively, the flakes can be prepared by spraying the molten R-Fe-B alloy in a form of particles and cooling the particles on a cooling plate into flat small pieces.

摘要： An apparatus for generating fine liquid metal droplets from a liquid or molten metal comprises a rotatable member situated in a pressurized or evacuated chamber. Means are provided for generating an electric field at the edge of the member having sufficient strength to overcome the surface tension of the metal. A liquid metal delivery means directs liquid metal onto a surface of the member over which the metal flows toward the edge as the member is spun. As the liquid metal leaves the surface at the edge, the force of the electric field causes fine liquid metal droplets which are more uniform and smaller than those produced without an electric field to form. A method for forming fine liquid metal droplets is also disclosed.

摘要： A method of producing a composite material of and Nb or V used for a superconductive wire comprises vacuum - melting two kinds of raw materials, 70 wt % Cu and 30 wt % Nb or V to form a melt; scattering the melt by a rotating disc to form a plurality of fine droplets each of which includes Cu and Nb or V at substantially the same compounding rate as the raw materials; and cooling rapidly the fine droplets by spraying an inert gas onto the scattering droplets thereby providing particulate bodies each of which dendrites of Nb or V are precipitated in Cu. The fine particles are compression - molded to form a molded product. The molded product is sintered to form an ingot in which the dendrites of Nb or V are dispersed homogeneously in the Cu base. The ingot is used for producing a superconductive wire, namely, it is subjected to cold rolling to reduce its sectional area, coating with Su or Ga, and diffusion heat-treating the wire to form Nb.sub.3 Sn or V.sub.3 Ga in the Cu base, whereby a superconductive wire is provided in which Nb.sub.3 Sn or V.sub.3 Ga are homogeneously dispersed in the Cu base.
