  • the present invention refers to metallic pieces or elements provided with orifices of generally small diameter, through which flows melted glass at high temperature, these pieces or elements themselves being brought to a high temperature.
  • the invention relates particularly to rotating hollow bodies or centrifuges, each provided with a peripheral band or wall having a plurality of orifices therein, through which the melted glass is projected in the form of filaments, which are then drawn out into fibers.
  • these pieces or elements are formed of alloys containing the following principal constituents: chromium, cobalt (a part of which may be replaced by nickel), tungsten, a not insignificant proportion of carbon, and a very small quantity of iron.
  • the proportions of these ditferent constituents may be comprised between the following limits: chromium 12% to 35%; cobalt 45% to 70%, capable of being replaced by nickel up to tungsten 3% to 15%; carbon 0.5% to 1.5%; and iron less than 1%
  • the small amount of iron may be replaced, at least in part, by traces of niobium and tantalum in quantities of about 0.05% or 0.06% of the alloy.
  • the alloys in accordance with the invention may also contain traces of titanium, molybdenum and aluminum.
  • These alloys may also comprise small quantities of stabilizers particularly in the form of silicon and manganese.
  • the proportion of these stabilizers may be used advantageously in the amount of 1% to 2%.
  • FIG. 1 shows comparative curves illustrating resistance to corrosion afforded by different metallic alloys against the effect of molten lass
  • FIG. 2 shows a rotary centrifuge for spinning fibers from molten glass composed in part, or in its entirety, from alloys in accordance with the invention.
  • FIG. 1 illustrate the comparative results .of losses in weight, in percentages, of two elements 10 (FIG. 2) of identical shape and size.
  • Curves 1 and 2 portray the results when the centrifuges are made of alloys of the above type, in accordance with the invention, as set forth below, while curve 3 illustrates the loss in weight when the centrifuge is ofidentical size but when it is fabricated from a commonly used alloy, as tabulated below.
  • the drawing shows, on the abscissas, the length of time during which the tested pieces were subjected to the action of the flow of melted glass and, on the ordinates, the percentage losses in weight.
  • Curves 1 and 2 portray, respectively, the behavior of the following alloys 1 and 2 composed of the following ingredients in the respective approximate quantities noted below:
  • Curve 3 illustrates the effects on an alloy 3 having the following composition by weight:
  • Alloys in accordance with the instant invention may be used in the fabrication of one of the layers in a composite metal structure seeking a high degree of resistance to the corrosive effects of molten glass, for example as disclosed in the application of Levecque et al., Serial No. 718,654, filed March 3, 1958, now US. Patent No. 3,031,717.
  • a hollow rotatable metallic body having a pcripheral wall with a plurality of orifices of small diameter through which are projected by centrifugal force thin filaments of molten glass, said body being composed of a metallic alloy having good mechanical resistance and high corrosion resistance and consisting essentially of the following ingredients in the respective proportions by Weight: chromium ranging from approximately 25% to 35%; a
  • cobalt and nickel content ranging from approximately to with the nickel content in a minor amount ranging up to 15%; tungsten from approximately 4% to 7%; carbon 1% to 1.2%; and iron less than 1%.
