Abstract
1396788 Continuous casting BATTELLE DEVELOPMENT CORP 17 May 1972 [27 May 1971 10 May 1972] 23217/72 Heading B3F [Also in Divisions C1 and C7] Fibres or continuous filaments 20, having a cross-sectional area less than 0À020 sq. in. and a width less than 0À20 in., are produced by introducing an edge 32 of a disc 30, rotating at 3-200 ft./sec., up to a depth of 0À06 in. into a pool of molten material 10 which is at a temperature less than 125% of its melting point in K. and has a surface tension of 10-2500 dynes/cm., so that an at least partially solidified film 20<SP>1</SP>, Fig. 4, is formed and projected to form a solid fibre or filament 20. The Cu, Al or Fe disc 30 may be cooled by internal liquid. Its edge is of rounded section and it may have a tapered margin as shown. There is a build-up 16 of material above the melt surface 15 (which may be protected by a flux layer), and further material is deposited on the film 20<SP>1</SP> as it passes through the build-up. The disc 30 may be raised above the pool surface 15, Fig. 2, after starting the process, so that material is deposited on the edge 32, only in the build-up 16. There may be a flow of molten material parallel to the direction of travel of the edge 32 at the pool surface. The axis of rotation need not be parallel to the surface 15. The material leaving the disc 30 may be still partly liquid and this portion may remelt the solid part so that the filament 20 reforms to a circular crosssection ; otherwise the filament has an elongated cross-section. However, if it becomes completely molten, air, N 2 or Ar is used as a coolant, possibly with a liquid mist. The molten material may be an alkali metal nitrate or Sn, Zn, Cu, Ni, Al, Fe, one of a number of steels mentioned, Al alloy, Ni-alloy, Cu-alloy or Zn-alloy. To produce fibres, the disc 30 has a notched edge, Fig. 6. There may be one notch, so that the fibre length is that of the circumference, or notches equally or unequally spaced so that several fibres of the same or different length are produced at each revolution. The disc may have a number of narrow, parallel, coaxial edges, possibly notched, to produce a number of filaments or fibres simultaneously.
