  • Publication number: 20040112566
    Abstract: A copper- nickel-silicon quench substrate rapidly solidifies molten alloy into microcrystalline or amorphous strip. The substrate is composed of a thermally conducting alloy. It has a two-phase microstructure with copper rich regions surrounded by a network of nickel silicide phases. The microstructure is substantially homogeneous. Casting of strip is accomplished with minimal surface degradation as a finction of casting time. The quantity of material cast during each run is improved without the toxicity encountered with copper-beryllium substrates.

  • Patent number: 6655446
    Abstract: An apparatus and method for casting metal strip includes a moving chill body that has a quench surface. A nozzle mechanism deposits a stream of molten metal on a quenching region of the quench surface to form the strip. The nozzle mechanism has an exit portion with a nozzle orifice. A depletion mechanism includes a plurality of independently controllable gas nozzles to supply a reducing gas to multiple zones of a depletion region located adjacent to and upstream from the quenching region. The gas flow profile can be controlled in each zone independently of controlling the gas flow in other zones. The reducing gas reacts exothermically to lower the density to provide a low density reducing atmosphere within the depletion and substantially prevent formation of gas pockets in the strip.

  • Patent number: 6622777
    Abstract: The apparatus and a method are used to produce metal fiber, which can increase production efficiency of metal fiber using a metal plate and simplify manufacturing equipments and includes a controlling device. The method for producing metal fiber includes steps of: making a frame in a vacuum condition by removing the air; vertically inserting an end of a metal plate between two induction coils arranged horizontally at an interval in the inside of the frame and heating and melting the end of the metal plate with heat generated by the induction coils; gradually moving the metal plate downwardly and bringing the end of the metal plate into contact with blades of a rotary disk, the rotary disk being horizontally mounted at a lower portion of the induction coils in the inside of the frame and rotating in a high speed; and solidifying metal fiber separated by the blades of the rotary disk.

  • Publication number: 20030159795
    Abstract: Disclosed are a method and an apparatus for producing a uranium foil with fine crystalline granules by forming the foil by the gravitational dropping of molten uranium or uranium alloy and rapidly cooling the foil by the contact with cooling rolls, and a foil produced thereby. In accordance with the present invention, a high-purity and high-quality uranium foil with an isotropic structure and fine crystalline granules is easily produced via a simple process without requiring hot rolling and heat treatment processes. The surface of the foil is prevented from oxidizing and residual stress is not imparted to the foil. The productivity and the economic efficiency of the foil are improved.

  • Publication number: 20030155097
    Abstract: The invention relates to a method for homogenizing a molten metal film, more particularly a steel film, by means of thin strip casting. According to the invention, the melt applied to a rotating strip is of a similar thickness to and possesses the same qualities wherever possible as the width of the strip. In order to homogenize the width of the strip, forces possessing a component perpendicular to the direction of conveyance of the strip are introduced, whereby homogenization of the profile of the molten metal film occurs.

  • Patent number: 6604570
    Abstract: An apparatus and method for continuously manufacturing metal filaments in mass production. In accordance with the present invention, molten metal is hung in a state freely depending from the tip of a metal bar by its surface tension without using any vessel. The metal filament manufacturing apparatus includes an induction coil upwardly bent in the form of a nose shape at regions thereof where metal filaments are discharged while being soared up, respectively, so as to prevent the molten metal of each of the metal bars from being affected by the induction coil during soaring of the metal filaments. The apparatus also includes wiping assembly for removing residual metal materials left on a spinning disk.
