Description
SPECIFICATION
Apparatus and process for rolling spin cast strip
This invention relates to an apparatus for rolling and spin casting metal strip.
While the invention is subject to a wide range of applications, it is especially suited for use in manufacturing thin strip material and will be particularly described in that connection.
In conventional chill block spinning, a metal jet impinges on a cold moving surface where it is shaped and solidfied. Chill blocks of varios geometries, including concave and convex discs, cylinders and drums, have been employed in the prior art. A typical example of this technique is disclosed in U.S. Patent No. 4,339,508 to Tsuya et al. which discloses a method for manufacturing a thin, flexible ribbon of superconductor material.
During the cooling of the molten material on the chill block, it is usually desirable to shape the melt.
Conventionally, this is accomplished by techniques such as shaping the wheel into different configurations and prolonging the contact of the melt on the wheel as disclosed in U.S. Patent No. 3,862,658 to
Bedell. In that patent, the period of contact is prolonged by use of such devices as gas jets, moving belts or rotating wheels.
Another technique for shaping the melt is disclosed in Japanese Patent Application NO. 56-23596 entitled "Production of Solid Solution Quick Cooling Material". A corona discharge is generated between an electrode and the injection material on the surface of a cooling roll. The result is a quickcooled material of a thin shape.
During the production of continuous metal filaments by chill block spinning, it is often difficult to form continuous filaments because of the breakage from oscillation of the solidified filament. U.S. Patent No. 3,938,583 to Kavash discloses, for example "A method for producing and concomitantly winding continuous metal filament in which a quenching wheel is used as a quenching element and in which sufficient pressure is exerted on the filament just beyond the point of solidification to counteract the tensional stress exhibited by the winder on the filament."
After a continuous strip has been formed, it may be rolled to a desired thickness. For example, in
U.S. Patent No. 3,659,643 to Pauels there is disclosed that "After the strip leaves the casting machine, it may be rolled for metallurgical improvement and coiled".
It is a problem underlying the present invention to incorporate spin casting with rolling so that the shape and metallurgical properties of the final spin cast thin strip are completed on a chill block.
In one aspect of the invention there is provided an apparatus for the continuous chill casting of metal or other strip comprising a casting roll, means for driving the roll, and means for dispensing the material to be cast as a thin strip of molten material onto the surface of the rotating roll, wherein there is provided at a point downstream from the dispensing means, when considered with respect to the direction of travel of the surface of the roll, a work roll having its axis parallel to that of the casting roll and forming therewith a gap of predetermined size through which the cast strip passes before removal from the casting roll, said work roll and said casting roll cooperating to roll the intermediate solidified cast strip to a predetermined size.
In a second aspect there is provided a process for the continuous chill casting of metal or other strip, which comprises continuously dispensing the molten material to be cast as a thin strip of molten material onto the surface of a rotating casting roll, allowing or causing the molten strip to solidify thereon, and stripping off the solidfied strip, wherein, after solidification, but before stripping from the casting roll, the solidified strip is rolled to a predetermined thickness by a work roll positioned adjacent the casting roll downstream, when considered in the direction of travel of the surface of the casting roll, from the point at which the molten material solidifies to provide said solidified strip.
The invention and further developments of the invention are now elucidated by means of preferred embodiments shown In the drawings:
Figure 1 is a diagrammatical view of an apparatus for manufacturing a thin strip in accordance with the present invention.
Figure 2 is a diagrammatical view of a second embodiment of the present invention
Referring to Figure 1, there is illustrated an apparatus 10 for casting and rolling a melt of material 14 into a continuous thin strip 12. The melt is poured from a nozzle 18 onto the outer peripheral surface 20 of a casting roll 16. Once the melt 14 has solidified into a continuous strip 13, it is rolled between the casting roll 16 and a work roll 22 and thinned into the desired thin strip 12.
There are two particular advantages of the apparatus and process disclosed in the present invention. First, the final thin continuovsss strip 12 is removed from the wheel 16 at the desired thickness so that it does not require further rolling. This is quite a significant economic advantage because of the time and effort generally required to handle a long length of thin strip material. Also, the final strip may have the desired metallurgical properties such as tensile strength and crystal structure. To obtain these properties after the strip has already been removed from the wheel may require the thin strip to be heated and/or passed through work rollers. The elimination of these additional steps at a later time provides a siynificant economic advantage of the present invention over the prior art.
The casting roll 16 is a specific embodiment of a conventional chill block. The casting roll or wheel 16 may be of any desired diameter and of any desired width. The selection of the material forming the chill wheel or casting roll must take into account the wettability between the molten material and the outer peripheral surface 20. This wettability is mainly determined by surface tensions of the melt and the substrate in the casting wheel. The wheel may be fabricated from any material which remains stable during contact with the melt such as for example steel, copper, aluminium, graphite, or alloys thereof. Also, the wheel may be formed of a material which is chrome plated or coated with a ceramic.Notwithstanding the materials mentioned above, the chill wheel or roll may be formed of any suitable material which can handle the casting and rolling of thin strip from a melt of desired material.
The melt 14 may be applied to the outer peripheral surface 20 of the roll 16 by conventional means such as through a nozzle 18 at one end of a tube 24. The molten material 14 is preferably maintained at a temperature above the liquids point of the melt by suitable means such as a heat resistor 26. Although a tube with a nozzle is illustrated, it is also within the scope of the present invention to apply the melt by other conventional techniques such as melting a feed rod by means of a heating coil with or without a susceptor around the rod, resistive heating or a direct energy source.
Once the melt contacts the outer surface 20 of the roll 16, the melt begins to solidify into an intermediate strip because of heat tranfer from the melt to the roll 16. This heat tranfer should be efficient enough for the material to completely solidify on the surface of the casting roll. To enhance the heat transfer, the casting roll may be cooled by any conventional means such as the application of a coolant through a cooling manifold 28 to the surface of the casting roll. The particular coolant does not make up a part of the present invention and may be constituted of conventional gases or liquids.
The thickness and width of the solidified intermediate thin strip 13, prior to rolling, can be determined by a number of factors. These include the surface tension between the melt 14 and the smooth, outer surface 20 of the chill wheel, the rotational speed of the chill wheel, the ejection pressure of the melt, the diameter of the nozzle, the melt temperature and the melt viscosity. The number of critical factors which can interact and affect the thickness of the melt reduce the probability of consistently forming a strip with the desired thickness.
The present invention regulates the final thickness of the thin strip by adding a work roll 22 to operate in conjuction with the casting roll 16. The work roll is disposed at a preselected position adjacent the outer peripheral surface of casting roll 16. A centre line 30 extends between the centre 32 of the casting roll and centre 34 of the work roll 22.
The centre line 30 bisects the strip 13 at the contact point 36 where outer surface 38 of work roll 22 and the outer surface 20 the casting roll 16 are tangentially disposed against opposite surfaces of strip 13. The contact point 36 is preferably located beyond the contact length of the strip on the casting roll. The contact length is defined as the length between the point at which the melt first contacts the casting roll and the point at which the solidified strip would pull away from the casting roll by centrifugal force. The advantage of selecting the contact point 36 to be beyond the contact length is that the work roll 22 can have a larger diameter without interfering with the tube 24. However, it is within the terms of the present invention to locate the contact point at any location on the solidified strip 13.
A positioning device (not shown) is provided to position the centre 34 of the work roll 22 with respect to the centre 32 of the casting roll 16. The distance between the two centres 32 and 34 is selected so that the space along the centre line 30 between the outer peripheral surface 20 of the work roll 16 and the outer peripheral surface 38 of the roll 22 precisely thins the solidified strip 13 as it passes between the rolls 16 and 22, into a strip 12 having a desired thickness or gauge.
A drive means (not shown) is provided to rotate each of the rolls 16 and 22 about their centres 32 and 34, repectively, at any desired speed. The rolls are rotated in opposite directions to one another so as to feed the strip 13 between them.
The step of rolling brings the strip to a finished gauge within a specified temper requirement range. Although not shown, it may be desirable to reheat and cool the strip after it leaves the apparatus 10 to affect the grain size, uniformity of grain size andíor the tensile strength of the material. This process could be accomplished downstream of the casting roll 16 and is not part of the present invention.
The work roll 22 may also provide additional cooling for the cast strip. To enhance this cooling, a cooling manifold 40 similar to manifold 28, may be provided. The coolant may function to both cool the thin strip and act as a lubricant between the cast strip and the roll 22. If desired, the coolant from coolant manifold 28 may also serve as a roll lubricant between the cast strip and the roll 16. It is further within the scope of the present invention to use any desired number of coolant manifolds and to position them as required with respect to the rolls 16 and 22. Also the type and amount of coolant which is delivered onto the rolls may be selected as required for the particular application.
Referring to Figure 2, there is illustrated a second embodiment of the present invention which differs from the first embodiment in that back-up rolls have been added to either the work wheel, the casting wheel, or both. Since the components of the apparatus 50 in Figure 2 are essentially the same as the components of apparatus 10, identical reference numbers are used for components which are substantially idenical.
Back-up rolls 52 and 54 may be added to roll 16 to provide additional mechanical stability and to support the roll 16 against the pressure exerted by the roll 22 thinning the strip 13. These rolls are preferably in contact with the outer peripheral surface 20 at points approximately equidistant from the centre line 30 extending between rolls 16 and 22. The rolls 52 and 54 rotate opposite to the rotation of roll 16. They may provide auxillary cooling of the casting roll 16 and if desired could have a coolant directed onto their outer peripheral surfaces 56 and 58. It is also within the terms of the present invention to use a single back-up roll which would preferably contact the casting roll at approximately where the centre line 30 crosses the outer peripheral surface 20. It is also within the present invention to use additional back-up rolls if desired.
A back-up roll 60 may also be used with work roll 22. The roll 60 would preferably be positioned so that its centre 62 would be placed substantially along the centre line 30 and its outer surface 64 would contact the outer surface 38 of the wheel 22 where the centre line 30 approximately crosses the two outer surfaces. Back-up roll 60 rotates in an opposite direction to roll 22 and is provided to stabilize the position of roll 22 with respect to roll 16 and to provide additional cooling if desired.
The present invention is preferably used with melts of material comprising metal, metal alloy, amorphous or semiconductor material. However, the present invention is not limited to any particular material but can be satisfactorily applied to any material suitable for spin casting and rolling.
It is apparent that there has been provided in accordance with this invention an apparatus and process for rolling spin cast strip which fully satisfy the objects, means, and advantages set forth hereinabove. While the invention has been described in combination with the specific embodiments thereof, it is evident that many alteratives, modifications, and variations will be apparent to those skilled in the art in the light of the foregoing description. According, it is intended to embrace all such alternatives, modifications, and variations as fall within the scope of the appended claims.
