Definitions

  • One of the two columns also vertically slidably supports a mold-holding means adapted to support a mold for receiving the molten metal.
  • Each one of the electrode-holding means is horizontally swingably mounted about the longitudinal axis of its associated column so that each electrodeholding means is adapted to describe a predetermined arcuate path which intersects the arcuate path described by. the other electrode-holding means.
  • mold-holding means is also horizontally swingable and adapted to position the mold during the remelting A process so that its longitudinal axis substantially coincides with the point of intersection of the arcuate paths of the electrode-holding means.
  • the installation of the invention includes two vertical columns. On each column there is provided an electrode-holding means which is swingable about the longitudinal axis of the column in ahorizontal direction; The electrodeholding means describetwo arcs which intersect each other. The longitudinal axis of the mold coincides with the point of intersection of the two arcs.
  • FIG. 1 is a schematic elevational view of the installation of this invention.
  • FIG. 2 is a schematic plan view of the installation illustrated in FIG. 1.
  • FIG. 1 illustrates a mold 10 for receiving the molten metal 'whichhas cylindrical inner wall means 11 and a flange 'portion 14 supported by the'two fork-like arms 23 of are mounted on the columns 30, respectively 30, so that they are secured against rotation.
  • the electrodes 40 and 40' which are to be consecutively melted down by passing an electric current therethrough, are respectively secured at their upper ends, where they are provided with axial flanged extension rods 41, 41, to the swingable members 52, 52 of electrode-holding means 50, respectively
  • the electrode-holding means 50 is mounted on the same column 30 as the mold-holding means 20, whereas the electrode-holding means 50' is mounted on a second vertical column 30, identical to the column 30.
  • the mold-holding means 20 as well as the electrode-holding means 50 and 50' can be vertically moved with the aid of a cable and winch arrangement 27, well-known per se, respectively 56, 56', supported on a beam 57 which is mounted on the corresponding columns 30, respectively 30'.
  • the cable and winch arrangements 27, 56 and 56 operate independently and can independently vertically move the electrode-holding means 20, 5l-and 51' in the vertical direction.
  • Each electrode-holding means 50, respectively 50' consists of an arrangement similar to that of the electrode-holding means 20.
  • the electrode-holding means 50, respectively 50' comprises a guide member 51, respectively 51', and a member 52, respectively 52', swingably mounted on the member 51, respectively 51'.
  • the guide members 51, 51 are respectively slidably mounted on the columns 30 30.
  • the swingable members 52, respectively 52', of the electrode-holding means 50 and 50', respectively, the mold-holding means 20 are provided each with a gear ring 24, 53, 53, which is respectively engaged by a gear wheel 25, 54, 54' mounted on the corresponding guide member 21, 51, 51' and which is driven by a corresponding electromotor 26, 55, 55'.
  • the installation of the invention is therefore adapted to respectively swing, with the aid of the electromotor 55, 55' and the electromotor 26, the swing member 52, 52 of the electrode-holding means 50, 50', together with the appurtenant electrode 40, 40, as well as the swing member 22 together with the appurtenant mold 10 about the longitudinal axis of the corresponding column 30, 30.
  • the mid-point of the base plate 62 which consists preferably of copper and on which the metal ingot 42 formed of metal that has solidified during the remelting process, is supported, is located close to an immaginary vertical line, which passes through the point of intersection of both arcs formed by the swing path S S of the electrodes 40 and 40 (see FIG. 2).
  • One of the poles of a source of electrical power (not illustrated) is connected by means of the electrical conducting means (for example, electrically conductive cables) to the extension rods 41, 41 of both electrodes 40 and 40 (the source of electrical power can, for example, consist of the secondary winding of a transformer).
  • The'other pole of the source of electrical power is connected by means of the electrical conducting means 61 to the support plate 62.
  • the mold is cooled during the remelting process by means of water which flows between the inner cylindrical wall 11 and the outer cylindrical wall 12, which define the hollow space 13 in the mold 10.
  • the conduction to and from the mold of the cooling water, specifically to and fromthe hollow space 13 is carried out by means of a flexible hose (not illustrated).
  • a cooling system of the aforedescribed type is, for example, described in the copending and coassigned application Ser. No. 773,622.
  • the electrodes 40, respectively40', to be remelted are closely consecutively exchanged by means of the electrode-holding means 50 and 50 and are transported in close succession to the mold 10.
  • the installation of the invention affords the advantages, compared with the electrode-holding means of the prior art, in considerably facilitating the transportation of the electrodes to be fused down to the mold as well as the transportation of the formed metal ingots from the installation to a storage area during the remelting process.
  • the ease of operation of the installation of the invention is based on the swingability of the electrode and mold-holding means and the installation operates flaw-free even when the electrodes to be fused have very large dimensions.
  • the electrode-holding means of the invention are also suitable in installations for electroslag remelting of metals which include only one column on which there is mounted an electrode holder as well as a mold support.
  • first and second electrode holding means respectively vertically slidably mounted on said first and second vertical columns and adapted to be fused down;
