Abstract
1470103 Continuous casting BATTELLE DEVELOPMENT CORP 19 April 1974 [23 April 1973] 17312/74 Heading B3F [Also in Divisions C1 and C7] A filament 10<SP>1</SP> (or fibres) of a material such as metal, alloy or Al 2 O 3 is (are) drawn off from a molten drop 51 of the material by a peripheral edge 32, of arcuate cross-section, of a rotating, rotationally-symmetrical member 30, the edge moving at more than 3 feet/sec., e.g. up to 100 feet/sec., without disturbing the stability of the drop. The drop may be formed by heating a solid member 20 in a region 50, Fig. 1, or by supplying molten metal 22, Fig. 4, to an orifice 40, where it may be reheated. The material of the drop is at a temperature above its M.Pt. and less than 125% of the M.Pt. in degrees Kelvin and has a surface tension of 10-2500 dynes/cm. and a viscosity of 10<SP>-3</SP>-1 poise. The drop need not be pendant as shown but could be sessile, i.e. supported from below, so that it can contact the lower run of the edge 32. It may be formed by an elongated orifice so as to be elongated to enable a number of edges to pass through it. The radius of curvature of the cross-section of the edge 32 on a tapered periphery 31 is 0À0005 to 0À10 inch and produces a filament 10 of non-circular cross-section and area less than 0À003 square inches. The effective filament diameter may be 0À0004 to 0À030 inches. The periphery may be of part-circular cross-section with a radius less than 0À5 inch. The rotated disc 30 (1-30 inches in diameter) may be of Al, Cu, Fe, Mo, Ni, steel or graphite or composed of several parts of different materials. It may be internally cooled. To produce fibres (see Division C7), the edge 32 is indented at intervals. The molten drop 51 may be produced by heating the solid material by oxyacetylene or propane torch, by resistance- or inductionheating or by electron beam. A local inert gas shield may protect the molten drop or the apparatus may be in an enclosure for vacuum or an inert gas. The metal melted may be Cr or Sn or an alloy based on Al, Cu, Fe (such as stainless steel), Ni, Sn or Zn; stainless or Ni-Cr steel may be used if an acetylene-rich oxyacetylene flame is used to reduce oxygen; an alloy based on Mg, Mo, Nb, Ta, Ti or Zr, or the metals Ti or Nb, may be used in a vacuum or inert gas. Instead of metal, Al 2 O 3 may be used (see Division C1).
