Definitions

  • the invention relates to a chill casting wheel for the continuous casting of filamentary material. More particularly, the invention relates to casting wheels used to cast glassy metal filaments.
  • an appropriate molten alloy is quenched at extreme quench rates, usually at least about 10 4 °C per second by extruding the molten alloy from a pressurized reservoir through an extrusion nozzle onto a high speed rotating quench surface as is representatively shown in U.S. Patent 4,142,571 for "Continuous Casting Method for Metallic Strips" issued March 6, 1978 to Narasimhan, hereby incorporated by reference.
  • Such filaments are necessarily thin, typically about 25-100 microns, due to the extreme heat transfer rate required to prevent substantial crystallization, though considerable selectivity may be exercised respecting the trans- dimensions and cross-section of the filament.
  • Contoured quench surfaces have been used to address the crowning problem on rollers.
  • casting wheels with contoured quench surfaces have been unsatisfactory because each particular contoured surface is effective only when specific use conditions of temperature and filament width are met.
  • a variation in filament width, extrusion temperature or filament quench rate prevents the contoured surface from properly compensating for crowning-type distortions.
  • Other problems with contoured quench surfaces include the cost and difficulty of initially machining the complex contours on the casting wheel quench surface and of periodically refurbishing the quench surface to maintain the precise contour.
  • the casting wheel includes an annular wheel core member which has axially extending channels formed about a circumferential, outer peripheral surface thereof and is adapted to rotate about a concentric axis of rotation.
  • a cylindrical, axially extending wheel rim member is concentrically connected to the core peripheral surface and has a preselected interference fit therewith to provide a preselected residual, circumferential tensile stress within the rim.
  • a coolant means directs a fluid coolant to the interior surface of the rim and through the channels of the wheel core.
  • the casting wheel of the invention includes a hub shaft member which has a concentric axis of rotation and two axial end portions. Each end portion delimits an axial coolant chamber having at least one, but preferably a plurality of coolant supply passages communicating radially therefrom.
  • An annular wheel core member is concentrically connected to the hub shaft and adapted to rotate therewith.
  • the wheel core has axially extending coolant channels formed about an outer peripheral surface thereof and two axially facing side portions.
  • a cylindrical, axially extending wheel rim member is concentrically connected to the peripheral core surface and has a preselected interference fit therewith to provide a residual, circumferential tensile stress within the rim.
  • Two annular flange members are connected concentric with the hub shaft and adjacent to each of the core side portions to delimit an annular coolant chamber at each side of the wheel core which communicates with its respective coolant supply passages.
  • the casting wheel of the invention is over eight times more resistant to crowning than ordinary casting wheels, and is able to cast filament of greater width having more uniform dimensions and physical properties.
  • the casting wheel provides improved heat transfer and more uniform quenching across the width of the wheel, and since the more rigid casting wheel construction has less tendency to become eccentric when rotating and subjected to thermal loads, the wheel is able to cast any width ribbon, less than the width of the wheel, at random locations across the quench surface without crowning problems.
  • the wheel is easier to refurbish because the casting wheel rim can be easily replaced whenever it becomes worn or damaged. Since the wheel core and other parts are reusable, costs are greatly reduced. With the two piece construction, different, individually suited materials can be used for the wheel core and the wheel rim as required.
  • the invention provides a less expensive and more versatile casting wheel that is more resistant to crowning, provides improved quenching, is easier to maintain and refurbish and is capable of casting wider filaments than ordinary casting wheels having thickened support sections or contoured quench surfaces.
  • filament is a slender body whose transverse dimensions are much smaller than its length.
  • filament includes wire, ribbon, sheet and the like of regular or irregular cross-section.
  • An extrusion means is comprised of a reservoir crucible 24 and an extrusion nozzle 26.
  • Molten alloy contained in crucible 24 is heated by a heating element 25, and pressurization of the crucible with an inert gas extrudes a molten stream through nozzle 26 located at the base of the crucible onto quench surface 23 of casting wheel 22.
  • the apparatus of this invention is suitable for forming polycrystalline strip of aluminum, tin, copper, iron, steel, stainless steel and the like.
  • metal alloys that upon rapid cooling from the melt form solid amorphous, glassy structures are preferred. Such alloys are well known to those skilled in the art, and examples are disclosed in U.S. Patent Nos. 3,427,154; 3,981,722 and others.
  • FIG. 2 shows the casting wheel of the invention generally at 22.
  • An annular wheel core member 7 has axially extending channels 8 formed about a circumferential, outer peripheral surface 11 thereof and is adapted to rotate about a concentric axis of rotation 28.
  • a cylindrical, axially extending wheel rim member 10 is concentrically connected to the core peripheral surface 11 and has a preselected interference fit therewith to provide a preselected, residual, circumferential tensile stress within the rim.
  • a coolant means directs a fluid coolant to the interior surface 29 of rim 10 through channels 8.
  • FIGS. 2 and 3 show a preferred embodiment of the casting wheel of the invention wherein the coolant means is comprised generally of hub shaft member 1 and two flange members 12.
  • hub shaft member 1 has a concentric axis of rotation 28 and two axial end portions 2.
  • the end portions delimit axial coolant chambers 3 and 4, and at least one, but preferably a plurality of coolant supply passages 5 and 6 communicate radially from chambers 3 and 4, respectively.
  • An annular wheel core member 7, concentrically connected to hub shaft 1, is adapted to rotate therewith and provides two axially facing side portions 9.
  • a plurality of axially extending channels 8 are formed about the outer peripheral surface 11 of the core, and a cylindrical, axially extending wheel rim 10 is mounted thereon.
  • Rim 10 has a preselected interference fit with core 7 to provide a preselected residual, circumferential tensile stress within rim 10.
  • Two annular flange members 12 are connected concentric with hub shaft 1 and adjacent to each of the core side portions 9 to delimit annular coolant chambers 13 and 14 at each side of wheel core 7 which communicate with their respective coolant supply passages 5 and 6.
  • Hub shaft 1 is constructed of a suitable material, such as metal, and provides two opposite end portions 2.
  • An inlet chamber 3 is cast or machined into one end portion and a plurality of outlet passages 5 are formed radially through hub shaft 1 to communicate and conduct coolant from chamber 3.
  • an outlet chamber 4 is cast or machined into the opposite end portion, and a plurality of passages 6 communicate radially from chamber 4.
  • Annular wheel core member 7 is constructed of a suitable material, such as stainless steel, but preferably is constructed of a material having a low coefficient of thermal expansion, such as INVAR (registered trademark), an iron-nickel alloy consisting essentially of 64% iron and 36% nickel.
  • Core 7 provides two axially facing side portions 9, and is concentrically connected to hub shaft 1 by means of a conventional annular locking assembly 15 to rotate with hub shaft 1.
  • INVAR registered trademark
  • Axially extending channels 8 are formed about outer peripheral surface 11 by a suitable method, such as machining.
  • Channels 8 allow a coolant flow across the width (measured axially) of core 7 which contacts the interior surface 29 of rim 10 and thereby cools quench surface 23.
  • channels 8 are spaced approximately 0.25 in (0.64 cm) apart and configured to provide a desired volume of coolant flow.
  • Cylindrical, axially extending wheel rim 10 is concentrically connected to peripheral core surface 11 with a preselected interference fit to provide a residual, circumferential tensile stress within rim 10.
  • a preferred material for rim 10 is a beryllium-copper alloy because of its higher thermal conductivity.
  • rim 10 is shrink fitted onto wheel core 7. For example, when producing a 15 in diameter casting wheel, rim 10 is constructed with an inside radius approximately 30 mils (0.076 cm) smaller than the radius of peripheral surface 11. Rim 10 is then heated to a temperature of approximately 600°F (316°C) to expand the radial dimension of the rim and allow placement about surface 11 of core 7.
  • rim 10 contracts to form an interference fit onto surface 11 which produces an internal residual tensile stress within the rim of approximately 75,000 psi (517,107 KPA). It is readily apparent that various amounts of interference fit are suitable, provided the resultant residual stress is less than the yield stress of the rim material but large enough to hold rim 10 in contact with core 7 against the thermal loads encountered during the casting operation.
  • Two annular radially extending support rings 20 connect to core 7 by means of an interference fit into a circumferential groove machined into each of the core side portions 9. Rings 20 support the edges of rim 10 and provide a sealing surface against which to connect the respective flange members 12. A plurality of openings 21 extend through ring 20 to allow coolant to flow to annular, radially extending channels 30 and 33 machined into the peripheral edges of their respective core side portions. Channels 30 and 33 are suitably sized and configured to conduct coolant between the respective rings 20 and channels 8.
  • Two annular, dished flange members 12 are connected concentric with hub shaft 1 and adjacent to each of the core side portions 9 to delimit an annular inlet coolant chamber 13 at one side of core 7 and an annular outlet coolant chamber 14 at the opposite side of core 7.
  • Coolant chamber 13 communicates with axial chamber 3 through passages 5
  • coolant chamber 14 communicates with axial chamber 4 through passages 6.
  • the outer edge of each flange 12 mates against its respective edge of rim 10 and the corresponding support ring 20, and is provided with a fluid seal, such as an elastomeric O-ring seal 31.
  • the inner edge of each flange 12 mates with hub shaft 1 and is provided with a fluid seal, such as an elastomeric O-ring seal 32.
  • a plurality of coolant vanes 16, connected to core 7 and disposed within chambers 13 and 14, direct coolant radially through chambers 13 and 14.
  • Suitable bearings 17 are positioned about hub shaft 1 and are spaced from the sides of flange members 12 by suitable spacers 18. Assembly nuts 19 are then threaded onto hub shaft 1 and suitably torqued to provide compressive, axial loads of approximately 12,000 lb - force (53,379 N) which hold flange members 12 in sealing engagement with hub shaft 1, rim 10 and support rings 20.
  • the end portions of hub shaft 1 are suitably connected to a source of fluid coolant by means of conventional rotating unions.
  • a suitable fluid coolant such as water flows from a source into axial chamber 3, then through passages 5 and into inlet chamber 13.
  • Vanes 16 direct coolant through openings 21 in support ring 20 and into channel 30, after which it flows through channels 8 contacting rim 10 to cool quench surface 23.
  • the coolant then enters channel 33 and flows through openings 21 into outlet chamber 14.
  • Vanes 16 direct the coolant to passages 6 through which it flows into axial chamber 4 and then away from the wheel.
  • Wheel 22 is spun up to a desired rotational speed and molten metal is extruded from crucible 24 through nozzle 26 onto quench surface 23 to produce continuous filament 27.
  • the residual circumferential tensile stress in rim 10 provides substantially improved crowning resistance by counteracting the thermally induced stresses that tend to increase the rim radius at the circumferential center line of the rim relative to the rim radius at the edges of the rim.
  • a thermal gradient, between a hot quench surface 23 and a cool interior surface 29, induces a thermal stress which tends to expand quench surface 23 relative to interior surface 29 and thereby tends to bend (crown) rim 10.
  • the residual tensile stress in rim 10 counteracts this thermal stress to hold rim 10 substantially flat across the width of core 7, thus providing a dimensionally stable quench surface 23 having marked resistance to crowning.
  • rim 10 is constructed as thin as practicable (measured radially) since less force is needed to restrain a thin member from crowning.
  • a rim thickness ranging from 0.60 in (0.15 cm) to 1/4 inch (0.64 cm) is preferred.
  • rim 10 should be thick enough to carry the residual rim stresses without deforming, and thick enough to damp the thermal energy wave propagating inward from the quench surface that would otherwise cause boiling of the coolant. In the shown embodiment, rim 10 is approximately 90 mils (0.23 cm) thick.
  • the thin rim also improves the radial heat transfer from quench surface 23 through the rim body to the coolant in channels 8, and thus provides a more uniform quench rate across the width (measured axially) of rim 10.
  • the casting wheel can be constructed to cast filaments greater than 5 cm in width.
  • the resultant casting wheel is not sensitive to the width of the filament cast thereon, provided the width is less than the width of the wheel quench surface.
  • a wide filament, a narrow filament or even a simultaneous grouping of narrow filaments can be cast on the casting wheel quench surface at random locations without degrading the ability of the casting wheel to resist crowning.
  • the casting wheel of the invention could be constructed as wide as a roller-type wheel, wherein the wheel width is greater than its diameter, and still retain its resistance to crowning. As a practical matter, however, the wheel width is limited by the allowable temperature rise of the coolant as it traverses the width through the coolant channels 8.
  • a casting wheel having a stainless steel wheel core was constructed in accordance with the invention and used to cast a filament of glassy metal alloy approximately 4 inches (10.16 cm) wide.
  • the physical profile of the quench surface across the axial, width of the wheel was measured before and during the casting operation. Upon comparing the profiles, the measured amount of crowning was approximately 0.5 mils (0.00127 cm).
  • the measured amount of crowning effect was approximately 4 mils (0.0102 cm).
  • the casting wheel of the present invention was approximately eight times more resistant to crowning than the ordinary casting wheel.
