Definitions
- Roethel [5 7 ABSTRACT Apparatus and method are described for continuously withdrawing filaments, wire and the like of uniform configuration from a bath of molten material, solid at ambient temperature, by immersion of the periphery of a rotating disc therein wherein the depth of immersion of the disc in the molten bath is automatically maintained substantially constant, continuously, irrespective of changes in the level of the bath.
- Patent Sheet 1 0f2 a mm Sept. 30,1975
- 2,139,020 is typical of the method and means used to produce solid filaments of predetermined length from a molten material, such as for example molten metals, metal alloys, inorganic or organic compositions and the like, wherein the periphery of a rotating disc is presented to the surface of the molten material and heat is continuously removed from the periphery of the disc to provoke solidification of the material thereon as a filament or wire which is continuously thrown from the periphery of the disc by centrifugal force.
- a manually operated jack 45 is provided for adjusting the position of the rotating disc relatively to the level of the bath.
- the configuration of the filaments formed on the disc depends on several factors including the speed of rotation of the disc, the temperature differential between the disc and bath, the shape of the periphery of the disc and the depth of immersion of the disc in the bath.
- the configuration of the filaments i.e., thickness and width have been found to vary to such an extent as to be unacceptable for the purposes intended.
- the instant invention relates in general to the continuous production of filaments or wires of uniform configuration by automatically and continuously maintaining the depth of immersion of a rotating disc in a bath of molten material substantially constant concomitantly with changes in the level of the bath. More particularly, the constant depth of immersion of the disc in the molten bath is maintained continuously and automatically by adjusting the effective density of the disc according to the physical laws of buoyancy.
- the invention provides novel supporting means for the rotating disc, including the disc drive means and accessory equipment, said supporting means being capable of adjustment for affecting changes in the effective density of the disc corresponding to the buoyant forces acting on the disc due to immersion of the disc in the bath.
- the depth of immersion of the disc will remain constant irrespective of any change in the level of the bath, i.e., either while justments thereof; and dampening means for absorbing any vibration attending rotation of the disc thereby precluding even slight variations in depth of immersion in the bath.
- FIG. 1 is a schematic perspective view of one embodiment of the filament-forming means of this invention
- FIG. 2 is a schematic side elevation of one form of disc used in the apparatus of FIG. 1;
- FIG. 3 is a vertical elevation on section line 33 of FIG. 2 showing the hollow construction of the hub which supports the disc;
- FIG. 4 is a side elevation of a modification of the wheel of FIG. 2;
- FIG. 5 is a side elevation of a further modification of the disc of FIG. 2;
- FIG. 6 is an elevation in section of a further modification in which a plurality or gang of discs are mounted on a single axle;
- FIG. 7 is a fragmentary view of the disc supporting means of FIG. 1 showing the use of a float associated therewith.
- the reservoir or tank for holding the molten material is schematically indicated at 10 mounted on a suitable support 11.
- a suitable heat source (not shown) is adapted to supply heat to the tank 10 to maintain the material therein molten.
- the material 12 forming the bath may be supplied to the tank 10 in any suitable way, as for example as a liquid fed into the tank 10 by feed pipe 13; or by introducing solid material in the form of metal pigs, discrete particles, wire and the like which melt upon entering the bath, typical materials suitable for forming filaments or fibers according to the improved process of this invention being materials which are solid at ambient temperature, and which include metals and metal alloys, latex (for forming rubber filaments) and certain fusible salts as for example stearate ammonium nitrate for use as fertilizer.
- FIGS. 1 and 2 One embodiment of the film forming disc is shown at 14 in FIGS. 1 and 2.
- This is a relatively thin metal disc having a central aperture 15 (see especially FIG. 3); and is assembled between integral hollow hub portions 16--l6 which form a chamber housing the central portion of the disc.
- the periphery of the disc projects beyond the chamber and may be a relatively narrow surface such as a knife edge but is preferably a narrow but substantially flat surface, as indicated at 17, for producing substantially flat filaments of consistently uniform width.
- the wheel 14 and in particular its periphery is cooled by a liquid coolant such as for example water arranged to be circulated through the hollow hub portions l616 and central aperture of the disc and to this end a hollow axle or drive shaft 18 is welded or otherwise secured to each hub portion in communication with the interior thereof said hollow drive shafts being in axial alignment.
- a liquid coolant such as for example water arranged to be circulated through the hollow hub portions l616 and central aperture of the disc and to this end a hollow axle or drive shaft 18 is welded or otherwise secured to each hub portion in communication with the interior thereof said hollow drive shafts being in axial alignment.
- One of said shafts constitutes the inlet for supplying a coolant from a source (not shown) to the hollow hub portions of the disc and the other an outlet for discharging the coolant therefrom.
- the temperature of the periphery 17 of the disc is maintained relatively low as compared to the temperature of the bath as a consequence of which molten material from the bath solidifies on the periphery of the disc in the form of an elongated filament or wire which, upon leaving the bath is thrown or otherwise remove from the rotating disc.
- the rotating cooled disc should be selected from metals which are used normally in other moulding processes.
- a copper metal disc may be employed successfully when metal fibers of lead, zinc, tin, magnesium and aluminum are produced.
- Metal fibers having higher melting points such as iron and nickel alloys may also be produced using copper or bronze discs.
- the invention contemplates treating the vertical sides of the disc with suitable materials, as for example an oxide coating, which treatment has been found to prevent molten bath material from adhering to the sides of the disc thereby ensuring flat filaments of substantially uniform width. It is also within the purview of the invention to employ, if necessary, a scraping device or air jet (not shown) to supplement centrifugal forces in dislodging the filaments from the periphery of the rotating disc.
- the disc supporting means one embodiment of the latter is illustrated in the drawings and indicated generally by the numeral 20.
- This comprises, in part, a rockable plate provided with a cut-out 21 in its front edge located immediately above the vessel 10 for accommodating the disc 14.
- the disc is assembled on the rockable plate by mounting its hollow shafts 1818 in suitable bearings 1919 secured to the top size of the plate at opposite sides, respectively, of the cut-out 21. As shown especially well in FIG.
- rockable plate 20 is supported for rocking movement in a plane substantially perpendicular to the plane of the molten bath 12 by a pair of pins 22-22 of knife-edges fixedly secured on the underside of the plate 20 intermediate its front and rear edges and at opposite ends thereof, respectively, each pin being fulcrumed on a hardened metal block 23 or equivalent support means mounted on the table 11.
- drive means for the disc 14 comprises a motor or equivalent power source 24 mounted on the top side of the rockable plate 20 and connected to shaft 18 of the disc 14 by belt and pulley.
- the combined weight of the rockable plate 20, the disc 14 and its drive means is adapted to be substantially balanced by counterbalancing means indicated generally at 25.
- this may comprise an arm 26 suitably secured at its forward end to the rear edge of the plate 20 and provided at its rear extremity with an adjustable weight 27 threadedly mounted thereon whereby adjustment of the latter may be made simply by moving the weight forwardly or rearwardly as the case may be.
- the disc supporting means i.e., the plate 20 may be rocked into position such that the periphery of the disc 14 will be completely clear of the molten material in the vessel 10; or by suitable adjustment of the weight 27 the plate 20 may be rocked into position such that the periphery of the disc is immersed in the molten bath to any selected depth.
- the disc Upon entering the molten bath the disc will be subject to the physical laws of buoyancy as a consequence of which further adjustment of the weight 27 may be required in order to hold the disc in the molten bath as the preselected depth.
- FIGS. 1 and 2 depict a disc 14 having a substantially flat continuous peripheral edge for forming flat filaments or wires of substantially continuous length modifications of the disc are contemplated within the scope of the invention.
- FIG. 4 illustrates a disc 29 similar to that shown in FIG. 1 except that the periphery of the disc is provided with a plurality of substantially equally spaced notches 30 the effect of which is to cast off relatively short lengths of filament or wire; while the filament-forming disc 31 of FIG. 5 has a knife-edge periphery 32 and one notch 33 the effect of which is to produce discontinuous but relatively long filaments or wires.
- FIG. 6 A still further modification of the filamentforming disc is shown in FIG. 6.
- a plurality or gang of discs 34 are assembled in substantially parallel planes between hollow hubs 3838.
- each hub 38 is provided with a sleeveportion 39
- each disc is provided with apertures 40 adjacent its periphery and a one-piece tubular drive shaft .
- onplug 43 is inserted in the tubu r sh its wall adjacent theouter faces of firstand last discs, respectively of the .gang of discs and-a core h ir ss a apertures 42 whereby a coolantpassing into one end of the shaft is deflected outwardly throughv said apertures 42, through the apertures 40 of the first and successive discs. thereby cooling the. peripheries,- thereof the coolant passing from the last disc into the apertures 42 at the opposite end of the tubular shaftandthence out therefrom. .7
- FIG. .7 A modification of the counterbalancemeans of this invention is shown in FIG. .7.
- lh invention contemplates supplementingtlie counter-- balance means by providing the rockable plate with afloat 44 supported inthe'molt'en bath 12 by an arm or equivalent support means 45 extending forwardly from the leading edge of the base-plate 20.
- the float is made of a suitable material, such as cast iron, to with-' stand the heat of the molten bath, and may take any suitable shape as for example a sphere.
- the float is in the form of a cast iron cup to which shot may be added or from which shot may be removed to compensate for large differences between the density of the disc and the specific gravity of the melt and thus making possible relatively sensitive adjustments of the counterweight 27.
- EXAMPLE 1 A gang-type disc assembly was used comprising five water-cooled discs 14 each 6 inches in diameter and having a plurality of notches in its periphery spaced circumferentially to form filaments about 1.25 inches long.
