Definitions

  • This invention relates generally to the continuous casting of metal and more particularly to a cooling system for cooling a casting wheel which is used in the continuous casting of metal.
  • Spray cooling has provided an easily controllable means for cooling the metal within the groove of an annular casting ring; however, this type of cooling has several drawbacks.
  • One of its drawbacks is that, since the spray is made to impinge at spaced intervals on the outside surface of the casting ring, the casting ring must be made as thin as possible in order to provide the best conduction of heat therethrough.
  • This particular construction results in greatly reduced strength of the annular casting ring, thereby allowing the metal of the casting ring to be easily deformed under the extremely high temperatures to which it is subjected.
  • Channel cooling of annular casting rings has usually been done with arcuately extending channels formed inwardly of the periphery of a casting ring, and adjacent to a casting groove. This has required that the casting ring be made of relatively thick wall sections in order to provide the necessary strength for proper support of the metal within the casting groove, and has also resulted in non-uniform cooling of the metal bar formed within the casting ring.
  • the coolant is relatively cool when first introduced into the coolant channels, but as the coolant flows along the circular path of the coolant channels it picks up heat dissipated from the molten metal that is confined within the casting ring.
  • the heat transfer rate decreases due to the decrease in temperature difference; and, the liquid coolant thereby produces a varying cooling rate at different points along the length of the coolant channel. Therefore, even it several short lengths of cooling channels were used around the casting ring, the cooling rate would vary along the length of each cooling channel.
  • the present invention overcomes these and other problems associated with previous cooling systems for casting rings by providing a plurality of radially extending channels which allow substantially uniform cooling of the casting ring along the length of the casting groove at all times.
  • the cooling system of the present invention possesses the advantages of:
  • the apparatus of the invention comprises a casting ring having radially extending coolant channels formed therein so that the coolant contacts the casting ring at a relatively short distance from the outer surface of the casting groove as the coolant is caused to flow through the radially extending channels in the casting ring, and along a very small increment of the length of the groove.
  • Coolant is introduced into the channels by a plurality of radially extending nozzles disposed adjacent the inner surface of the casting ring which also force coolant along the radially extending sectional channels.
  • the particular arrangement of the nozzles can be easily varied so that different uniform rates of cooling can be produced in different zones of the casting ring if that should be desired.
  • FIG. 1 is an elevational view of a casting machine utilizing an embodiment of the invention
  • FIG. 2 is a cross-sectional View of a casting ring embodying the invention
  • FIG. 3 is a cross-sectional view of the casting ring shown in FIG. 2, removed from its associated structure;
  • FIG. 4 is a cross-sectional view of a second embodiment of the present invention.
  • FIG. 5 is an enlarged sectional view of a portion of the second embodiment of the invention shown in FIG. 4, partially broken away to illustrate the position of the cooling channels within the casting ring;
  • FIG. 6 is a schematic illustration showing a cooling manifold and nozzle arrangement for zoned cooling that can be utilized in the present invention.
  • FIG. 7 shows a means for rotating the cooling manifold shown in FIG. 4.
  • FIG. 1 illustrates a casting machine in which the invention is embodied. It is to be understood, however, that the invention is not limited in any way by the details disclosed herein since it may be embodied in other equivalent forms.
  • the casting machine has a casting wheel 10, a frame 11 rotatably supporting the casting wheel 10 and an endless belt 12 encircling a portion of the casting wheel 10.
  • the periphery of the casting wheel 10 carries the casting ring 14 wherein the invention is embodied.
  • the first embodiment of the invention is seen to comprise a disc shaped mounting plate 15 which is integral with, and extends perpendicularly outward from a support shaft 13, the shaft 13 bemg rotatably journaled in a frame 11.
  • a retaining annulus 18 has the same diameter as the support plate 15 and is spaced from the support plate 15 so that their axes of rotation coincide.
  • An annular casting ring 14 is retained between the support plate 15 and the annulus 18 in appropriate annular slots 19 which are formed in the inner faces of the support plate 15 and the annulus 18.
  • a plurality of bolts 16 extend through the support plate 15, the casting ring 14 and the annulus 18 to hold the assembly together to form the casting wheel 10.
  • the casting ring 14 defines a casting groove 20 in its outer peripheral surface 20a, and has transverse, outwardly extending lips 21 adjacent the mouth of the groove 20, the lips 21 being received by the slots 19 that are provided in the support plate 15 and the annulus 18.
  • Two narrow coolant channels 24 extend radially inwardly from beneath the lips 12 of the casting ring 14 adjacent the inner surface 20a of the casting groove 20, and converge at a point along a radius of the casting ring 14 where the coolant is introduced.
  • a plurality of these channels 24 are formed at closely spaced intervals about the circumference of the casting ring 14.
  • the outer ends of the coolant channels 24 terminate immediately below the outwardly extending lips 21 of the casting ring 14; and, the coolant is returned inwardly through the return channels 25 which communicate with the channels 24.
  • This allows coolant to be introduced into the cooling channels 24, to flow along the channels 24 adjacent the casting groove 20 while removing heat conducted from the molten metal through the casting ring 14, and to exit inwardly toward the center of the casting wheel along the channels 25.
  • the channels 24 must have a narrow width and be spaced far enough apart so that support webs 24 between the channels 24 provide enough strength to keep the casting ring 14 from warping or otherwise deteriorating when hot, molten metal is poured within the casting groove 20.
  • the second embodiment of the invention is seen to comprise a disc shaped mounting plate 15 integral with and extending perpendicularly outward from a support shaft 13.
  • a retaining annulus 18' has the same diameter as the support plate 15' and is spaced from the support plate 15' so that their axes of rotation coincide.
  • a U-shaped, removable mold portion 26 is retained between the support plate 14 and the annulus 18 in appropriate annular slots 19' which are formed in the inner faces of the support plate 15 and the annulus 18'.
  • a support member 28 is also carried between the support plate 15' and the annulus 18' by bolts 16, and serves to support the removable mold portion 26.
  • the entire wheel assembly 10 is rotatably carried by a frame 11 in which the support shaft 13 is journaled.
  • the removable mold member 26 defines a casting groove 20, and has lateral, outwardly extending lips 21' adjacent the mouth of the groove the lips being received by the slots 19 provided in the support plate 15' and the annulus 18.
  • a plurality of set screws 23 serves to retain the lips 21' of the removable mold portion 26 in the slots 19.
  • the support member 28 is mounted so that its outside surface is continuous with the inside surface of the removable mold portion 26 by providing a recess 27 in which the removable portion 26 rests.
  • the support member 28 comprises two mating sections 28a and 2812 so that the support member 28 can be assembled around the base portion of the removable mold portion 26.
  • the removable mold portion 26 has coolant channels 44, each of which is formed inwardly of the recess 27 along a given radius of the support member 28 and opens into the recess 27. A plurality of these channels 44 are formed at closely spaced intervals about the circumference of the support member 28.
  • An inlet port 45 extends inwardly of the innermost point of each of the channels 44, through the support member 28, and opens on the inner surface of the support member 28; therefore, coolant can be introduced into the channels 44 and flow radially outward, while remaining in contact at all times with the inside surface of mold portion 26.
  • Return channels 30 extend radially inward from the outermost extending ends of the channels 44.
  • a first form of coolant introductory means which comprises a coolant manifold 32 having outwardly extending nozzles 34 aligned with the ports 45 in the support member 28 for Y spraying coolant into the channels 44.
  • the coolant manifold 32 communicates with a coolant supply pipe 35 which has a valve 36 therein for regulating the flow of coolant through the pipe 35, the manifold 32 and hence the channels 44 in the support member 28. Therefore, regulating the valve 36 will vary the flow of coolant through the channels 44, hence the rate of heat transferred from any metal that may be within the casting groove 20.
  • FIG. 6 a second form of introductory means is shown providing zoned cooling.
  • the only necessary changes in the first embodiment of the introductory means are in the coolant manifold 32 which is shown as a coolant manifold 32 in FIG. 6.
  • Any number of cooling zones can be provided in the introductory means, but only three such cooling zones A, B and C are shown in the embodiment of FIG. 6.
  • the coolant manifold 32 is stationary within the cavity formed in the wheel assembly, with a first zone A having a plurality of closely spaced nozzles 34 extending from the coolant manifold 32 so as to introduce a large volume of coolant into the channels 44.
  • the zone A is usually placed adjacent to support ring 28, beginning at that point of the mold portion 26 which receives the liquid metal.
  • a second zone B is provided by a plurality of nozzles 34', which are spaced a greater distance apart than those nozzles 34' in zone A.
  • the cooling zone B is spaced clockwise from, and adjacent to, zone A.
  • These nozzles 34' of zone B are usually spaced a distance further apart than those of zone A, since the metal is substantially solid by the time it passes through zone A, and less heat transfer is needed.
  • Zone B usually extends clockwise around the manifold 32 to that point on the mold portion 26 at which the solidified metal bar is extracted from the casting groove 20.
  • zone C Extending from the end of zone B, clockwise around the manifold 32 to the beginning of zone A, is the cooling zone C which is provided by a plurality of nozzles 34, the nozzles 34' being spaced a greater distance apart than either those of zone A or those of zone B. Since the solodified metal bar has been extracted from the casting groove during the time the support member 28 is adjacent the cooling zone C, less flow of coolant is needed than in zones A and B since the casting groove is open and free from contact with the molten metal. Thus, it is seen that zone A provides the greatest cooling capacity for the liquid metal, zone B provides a lesser cooling capacity than zone A, and zone C provides the least cooling capacity of the three zones A, B and C. It will be further seen that more or fewer cooling zones can be provided by the nozzles 34 as required to solidify the liquid metal injected into the casting groove 20 and to cool this solidified bar to a desired temperature before the bar is extracted from the casting groove 20.
  • FIG. 7 a third embodiment of the introductory means is shown.
  • This embodiment uses an independently rotatable manifold 32".
  • the coolant manifold 32" has the same general construction as the coolant manifold 32, but is rotatably journaled in a support stand 40 so that the manifold 32" can be rotated in the direction of rotation of the casting wheel 10, or in the opposite direction of rotation from the casting wheel 10.
  • a coupling 42 is provided at the end of a support tube 43 so that water can be introduced into the coolant manifold 32" via the support tube 43.
  • the flow of coolant in this third form of the introductory means is controlled by the valve 36 as shown in FIG. 1.
  • a casting ring having in its peripheral surface a casting groove and having formed therein a plurality of separate first channels each of which extends adjacent said casting groove from inwardly of said casting groove substantially to said peripheral surface and each of which is along its length substantially equi-distant from said casting groove, means for positioning said casting ring for rotation about an axis and for providing with said casting ring a plurality of second channels each of which is continuous with one of said first channels and extends inwardly toward said axis, and means positioned inwardly of said casting groove for flowing coolant through said first channels and said second channels.
  • each of said first channels extends radially outward toward said peripheral surface.
  • each of said second channels extends radially inward away from said peripheral surface.
  • said means positioned inwardly of said casting groove includes a plurality of ports in said casting ring continuous with said first channels, a plurality of nozzles adjacent said ports, and means for providing said coolant to said nozzles.
  • said casting ring includes a support member having a recess and a mold portion defining said casting groove positioned in said recess.
  • a cooling system comprising an annular support member shaped to receive said mold portion and having a plurality of radially extending channels therein opening against said mold portion so that coolant flowing through each of said channels is confined on one side by said support member and on the other side by said mold portion, means for introducing coolant into said channels, said means comprising a circular coolant manifold rotatable about said axis of said mold portion independently of said mold portion and having outwardly extending nozzles around the periphery thereof, and valve means for judiciously regulating the flow of coolant through said nozzles.
  • a cooling system comprising an annular support member shaped to receive said mold portion and having a plurality of radially extending channels therein opening against said mold portion so that coolant flowing through each of said channels is confined on one side by said support member and on the other side by said mold portion, and means for introducing coolant into said channel comprising a circular coolant manifold rotatable about said axis of said mold portion independently of said mold portion and having a plurality of equally-spaced coolant-discharging nozzles around the periphery thereof disposed adjacent entrances of said channels, and driving means for rotating said coolant manifold.
