Definitions

  • This invention relates to that kind of producing fibers from glass, slag and the like meltal ble materials, according to which the hot molten mass is flown in a preferably continuous thin stream from the outlet of a suitable tank, such as a melting furnace, onto the surface of a rapidly rotating disc from which it is thrown olf by centrifugal action in the form of fine fibers or filaments.
  • a suitable tank such as a melting furnace
  • the invention has for its object to so improve this known method as to allow the production of fibers of greater fmeness than could hitherto be produced with this method.
  • the present invention essentially consists in subjecting'the mass thrown off the disc in a divided state to a further sub-division of still finer grade, which is attained by causing the individual mass particles to pass from the disc surface proper to a surface contiguous with and constituting an enlargement of the .former and surrounding it like an aureola, this surface being formed by a multiplicity of substantially radial linear members along which the divided mass is caused to travel. and be further subdivided so as to beI converted into fibers of the greatest fineness.
  • the centrifuging disc is provided at its periphery with a multiplicity of thin metal rods or wires extending substantially radially from the disc and lying ush with the top surface of the latter.
  • the said rods or wires preferably consist of platinum, chromium-nickel-steel or another metal or metal alloy having a high heat resistance. They are made of great neness, having for example a thickness of only one tenth of a millimeter.
  • the wires are attached by welding, soldering Or in any other suitable manner to holding rings or covers of the disc or to the disc itself.
  • the partscarrying the Wires preferably consist of the same heat-resistant metal or metal alloy as the wires or are provided with a coating of such metal. This wire aureola considerably enlarges the diameter of the centrifuging disc. It may be of a dimension to increase the said diameter for example from about 200 millimeters to about from 400 to 500 millimeters.
  • the centrifuging disc may be disposed in a horizontal or inclined plane.
  • the molten mass delivered to the revolving disc is guided by the said wires beyond the periphery of the disc proper, subjected thereby to an utterly fine division and thrown as fibers or filaments into the surrounding space only at the free ends of the wires.
  • great neness of the fibers attainable in this way may even be increased by an increased speed of rotation of the revolving disc.
  • the supply of a predetermined quantity of molten mass yields a correspondingly large volumetric quantity of fibers.
  • the resulting fibrous product has less density, a considerably looser texture and therefore a higher insulating eiciency than products obtained by Athe y corresponding old method.
  • the line bers or filaments are much more suited for undergoing treatments for textile and like purposes.
  • FIG. 1 is an elevational view, partly in section, of an apparatus for producing glass fibers with the improved centrifuging device according to the invention.
  • Fig. 2 is a vertical section and Fig. 3 a plan view of the centrifuging device on an enlarged scale.
  • Fig. 4 is a section similar to Fig. 2 of a somewhat modified form of device.
  • Fig. 5 is a partial sectionthrough another modification
  • Fig. 6 is a vertical section of still another form of centrifuging device.
  • the numeral I designates a melting furnace for the material. such as glass, from which the bers are to be produced.
  • the Afurnace has in its bottom an outlet I I through which a stream of molten material I2 is delivered to the top surface of a cylindrical body or disc I3 of suitable refractory material, which is caused to revolve at high speed and from which the molten mass is thrown off in divided state and drawn to fibers by centrifugal action.
  • I4 is a jacket surrounding the space of fiber formation.
  • the disc I3 is fastened by means of a suitable armature I5 to a vertical shaft I6 which may be mounted stationarily or in a truck I1, as shown in Fig. l. Rotating power is transmitted to the device through a belt pulley I8 or any other suitable drive.
  • the disc I3 is provided at its periphery with a multiplicity of thin metal wires I9 extending substantially radially of the disc and lying flush with the top surface thereof, forming a kind of aureola surrounding the disc.
  • the disc I3 has a central projection 2l hooded by a metal cap 22 to which the wires I9 are attached.
  • the cylindrical armature I5 holding the disc I3 has fitted on its upper margin a metallic border ring 23 of inverted U-shape the surface of which lies flush with the surface of the disc I3.
  • the wires I9 are clamped with their inner ends between the disc and the border ring and fastened to the latter.
  • the disc I3 is formed in one piece with a hollow stub-shaft 24 and is seated at the lower end of this shaft. 'Ihe wires I9 are fastened directly to the disc I3.
  • the stub-shaft is coupled by the .armature I5 with the driving shaft I 6 which is likewise hollow.
  • a continuous channel 25 is formed in the shafts I6 and 24 through which air or another medium may be admitted.
  • the molten mass is supplied to the disc I3 by a chute 26.
  • a method of producing fibers from molten glass, slag and the like meltable materials consisting in delivering a thin stream of molten material onto the surface of a disc-like body, imparting high-speed rotation to this body and thereby causing the supplied molten mass to be divided into small particles and thrown off the disc by centrifugal action, passing the divided mass as it leaves the disc surface onto another surface contiguous and flush with the former and formed by a multiplicity of thin linear members fast to and surrounding the disc like an aureola, the mass particles thrown off the disc being guided along and subjected to further subdivision by the said members so as to yield fibers of greatest fineness.
