Definitions

  • the invention also provides a centrifuging device by which it is possible to put into operation the method described above.
  • the centrifuging device comprises an enclosure having a filling orifice; means for rotating the said enclosure about an axis preferably passing through the said orifice; at least two conduits, which form extensions of the enclosure, each being terminated at its free end by an orifice provided with a sealing cover, and each having its longitudinal axis substantially perpendicular to the axis of rotation of the enclosure, all the conduits being arranged substantially in the same plane; and a refractory lining covering the internal wall of the enclosure and side walls of the conduits.
  • the refractory lining covering the internal wall of the enclosure and the conduits is terminated at the ends of the conduits by a portion which is slightly bent back (or folded) towards the centre of the conduit, which has the effect of breaking the active force of the molten metal and of reducing any risk of deterioration of the sealing cover by the metal.
  • FIG. 2 is a plan view of the device, with ancillary apparatus
