Definitions

  • the present invention relates to apparatus and method for rapid solidification casting of high temperature and/or reactive metallic alloys.
  • Melt-spinning is one well established rapid solidification technique which has frequently been used to cast amorphous metal ribbons.
  • a stable liquid jet of molten material is formed by ejection of the liquid through an appropriate orifice or nozzle, and then.the jet of molten material is solidified on a moving heat sink.
  • This technique is further described on pages 13 through 17 of a technical report, AFMR-TR-78-70 entitled "Amorphous Glassy Metals and Microcrystalline Alloys For Aerospace Applications" by E. W. Collings, R. E. Maringer, and C. E. Mobley.
  • British Patent 1,428-,691 discloses melting materials in water-cooled molds. The melt is then solidified in situ. Again, this patent offers no teaching of a technique for the extraction of liquid metal from a water-cooled mold through a constricted orifice.
  • a crucible which is constructed of a thermally conductive material such as copper, brass, graphite, etc., is employed for holding a metal charge.
  • Means for supplying heat to melt the metal charge contained in the crucible are employed to form a melt of molten metal.
  • One or more cooling passages internal to said crucible for passing a cooling medium therethrough provides a solidified layer of the melt for preventing interaction between the melt and the crucible.
  • a nozzle forming an integral part of the crucible is employed to eject a stream of molten metal, and a means for rapidly quencning the stream are provided.
  • a means for controlling the ejection of the molten metal allows the charge to be fully melted before the molten material is ejected.
  • a method for making continuous metal filaments directly from a melt is described.
  • a charge of molten metal is contained in a crucible with an attached nozzle.
  • a solidified layer of the melt is provided to prevent interaction between the melt and the crucible.
  • the molten metal is ejected through the nozzle and forms a stream.
  • the stream impinges onto a chill surface provided by a heat extracting member. As the chill surface is advanced, the molten stream is quenched by the chill surface at a rapid rate and produces a continuous metal strip.
  • a heat extracting crucible 2 is employed for containing molten metal 4.
  • a nozzle 6 is attached to heat extracting crucible 2 and forms an integral part thereof.
  • the heat extracting crucible 2 and the nozzle 6 are preferably made of a high conductivity material such as copper, brass or graphite.
  • the crucible In order to increase the heat extracting capacity of the heat extracting crucible 2, it is preferred that the crucible have a channel 8 for the passage of water therethrough.
  • the water inlet 10 and outlet 12 allow the water to flow through the channel 8.
  • the molten metal 4 is ejected through the nozzle 6.
  • the flow of the molten metal 4 is controlled by a shutter 14.
  • the shutter is guided by a tracx 15.
  • Heat is supplied to melt a metal charge and/or to the molten metal 4 by an arc 16 which is struck between an electrode 18 and the charge of the molten metal 4.
  • the electrode 18 is attached to an electrode holder 20 which is water-cooled.
  • a potential is supplied by voltage supply 22 between the electrode holder 20 and the heat extracting crucible 2. It should be appreciated that other heating means such as an e-beam or a laser beam could be employed to supply heat to the molten metal 4.
  • the heat extracting crucible 2 has a crucible cover 24 attached thereto.
  • the crucible 2 and the crucible cover 24 form a chamber 25 which provides control of the atmosphere over the molten metal 4.
  • the crucible cover 24 has sidewalls 26 which are watercooled by cool.ing coils 28.
  • the crucible cover 24 has a removable top 30.
  • the top 30 is connected to the sidewalls 26 via a flange 32.
  • Electrode holder 20 passes through the removable top 30 and is electrically insulated from the top by seal 34.
  • a gas outlet 36 in the removable top 30 is connected to a two-way valve 38 .
  • the valve 38 in one position allows gas to be evacuated from the chamber 25 by a vacuum pump not shown and in the second position allows an inert atmosphere such as argon to be supplied to the chamber 25.
  • Fig. 2 is a schematic representation of the molten metal supply of Fig. 1 used in combination with a rotating chill wheel 40 having a circumferential edge 42.
  • the chill wheel 40 is rotated by a motor 44.
  • the heat extracting crucible 2 may be positioned relative to the chill wheel 40 by two orthogonol slide mechanisms 46 and 48.
  • the shutter 14 is opened by the shutter release 50.
  • a second chamber 52 encloses the chill wheel 40 and the heat extracting crucible 2, as is illustrated in Fig. 3.
  • the electrode holder 20 passes through the removable top 30 of the melt chamber 25.
  • the removable top 30 also serves as the top of the second chamber 52.
  • the removable top 30 has an inlet 56 for evacuating the melt chamber and a valve 58 to block the inlet 56.
  • an outlet 60 having a valve 62 is used to provide a controlled atmosphere by the inlet of a gas such as argon.
  • Inlet 64 and outlet 67 respectively allow evacuation and refilling of the second chamber 52 with a gas such as argon.
  • the valves 66 and 68 control the flow of gas respectively through the inlet 64 and outlet 67.
  • a shutter 14 it is possible to use other means to constrain the flow of molten material through the nozzle 6.
  • One such other mean would be to place a small plug of low melting material in the nozzle 6. As the melt reaches temperature, the low melting material would soften; and when the argon pressure is increased in the melt chamber 25, the plug would be dislodged from the nozzle 6, and a stream would flow through the nozzle 6.
  • FIG. 4 Another means to control the ejection of a molten material is illustrated in Fig. 4.
  • a water- cooled stopper rod 70 is employed to block the passage of the nozzle 6.
  • the stream can be rapidly quenched by impinging the stream with a jet of gas 78 from a gas nozzle 80 thereby atomizing the stream and promoting its cooling to form a rapidly- cooled powder product.
  • An insulating nozzle sleeve 72 lines the nozzle 6.
  • the nozzle sleeve 72 may be heated by an induction coil 74 in the event that the nozzle sleeve is coupleable to the magnetic field of the induction coil, or alternatively a graphite susceptor 76 may be contacted to the nozzle sleeve, spare and heat induced into the graphite susceptor 76.
  • two electrodes are employed.
  • the electrodes 18 are held in electrode holders 20, and mounted through the removable top 30 by pivotable sealed joints 77.
  • a voltage from a supply (not shown) is applied between the two electrode holders.
  • An arc is struck between the electrodes 18 and the molten material 4.
  • the melt was ejected through the nozzle by sliding away the shutter while increasing the pressure in the furnace by about 10cm of mercury.
  • Typical orifice sizes for the nozzle were between about 0.06 inch (0.15cm) and 0.1 inch (0.25 cm). The lower limit assures that it is possible to maintain a stream which does not chokeoff, while the upper limit assures the flow will be sufficiently restrained to establish a filament of uniform cross-section.
