Definitions

  • This invention relates to the continuous casting of ingots in horizontally disposed molds, especially ingots of light metals.
  • light metals it is to be understood that this includes aluminum and the alloys in which that metal predominates as well as magnesium and those alloys wherein that metal is the major component.
  • ingots be continuously cast in horizontally positioned molds and either cut to desired length or passed directly to a rolling mill.
  • the molten metal supply is at some distance from the mold and the metal travels to the mold through a conduit. In that case there is a problem of maintaining a proper metal temperature during transfer,
  • the art has shown horizontal molds having either no constriction of metal flow at the head end, or a constriction in the form of a plate having a central opening therein. Under such conditions the ingots do not have a uniform grain structure or a satisfactory surface.
  • ingot refers to a cast rod or bar as well as cast bodies of much greater cross sectional dimensions adapted to the production of large Wrought articles.
  • the term is also used herein in a broad sense to embrace both the partially formed ingot and the completely solidified product.
  • the ingots may have different cross sectional shapes, for example, circular, rectangular, polygonal or oval.
  • Another object is to provide a method of feeding molten metal to a horizontally disposed mold wherein the metal is introduced to the mold under a relatively low pressure and over the lower portion of the inner mold wall surface.
  • a further object is to provide a method of supplying molten metal to a horizontally disposed mold wherein the distribution of metal within the mold is so controlled that substantially uniform freezing conditions exist around the mold wall where freezing starts.
  • Another object is to provide a method of supplying molten metal to a chilled horizontally positioned mold which permits initiating freezing at the head of the mold and thus utilize effectively the entire chilled mold surface to promote formation of an ingot.
  • Still another object is to provide a method that is especially adapted to the continuous casting of light metal ingots in a horizontal position that yields a product having a uniform grain size across the ingot cross section.
  • a further object is to provide apparatus for the continuous casting of an ingot in a horizontally disposed chilled mold closed at its head end with a heat insulating material except for a relatively narrow gate opening whereby the metal freezing rate is substantially the same at the top and bottom of the mold.
  • Another object is to provide continuous horizontal casting mold apparatus having a relatively narrow elongated gate in a heat insulative mold head plate which will deliver metal to the lower mold section in close proximity to the inner wall of the mold.
  • Another object is to provide continuous horizontal casting mold apparatus wherein the metal supply receptacle adjoins a mold having internally chilled walls and coolant is discharged upon the emerging ingot whereby the molten metal is rapidly frozen and a high quality ingot is produced.
  • a further object is to provide continuous horizontal casting mold apparatus wherein the seal between the mold and head plate is combined with the lubricant distribution system.

  • FIG. 6 an end view, represents a modification of the gate opening in the mold head plate seen in FIG. 2;
  • FIG. 7 also an end view, represents the arrangement of the gate opening in the head plate for casting a rectangular shaped ingot
  • FIG. 8 another end View, represents a modification of the gate opening in the head plate adapted to casting a polygonally shaped ingot.
  • Our method of casting is predicated upon the discovery that high quality ingots can be produced in a horizontally disposed chilled mold by introducing substantially all the molten metal in the lower half section of the mold and in a relatively thin stream generally conforming to the shape of the mold and close to the inner mold wall thereof.
  • the metal is introduced under a relatively low pressure and hence the stream extends but a relatively short distance into the mold.
  • the metal freezing conditions which characterize the central feeding of a horizontal mold in the prior art are substantially eliminated by our method of combining contoured feeding with a controlled chilling of the metal.
  • the contoured feeding appears to establish thermal conditions within the molten metal at the head of the ingot which aid in the rapid extraction of heat with resultant improvement in uniformity of internal structure and surface quality.
  • the head end when continuously casting an ingot in a horizontally positioned mold, the head end must be closed except for the gate which admits metal to the mold and the exit or discharge end is filled with the freezing ingot.
  • the head closure member is referred to herein as a head or header plate.
  • the plate of course, must be made of a refractory heat insulative material to withstand heat and any chemical action of the molten metal.
  • the molten metal for filling the mold and producing the ingot is supplied from a suitable reservoir adjacent the mold so that the distance the metal travels from the reservoir to the mold is short and there is substantially no drop in temperature during transfer. We therefore consider that the molten metal entering the mold has substantially the temperature of that in the reservoir.
  • the mold as stated above and described in greater detail below, is chilled by a liquid coolant so that there is a high rate of heat transfer from metal to mold. Furthermore, in our preferred practice additional heat is removed from the ingot emerging from the mold through direct application of coolant to the ingot surface. We have found it to be advantageous to use the coolant that has circulated in the chamber around the mold and project it upon the moving ingot at a low angle.
  • the molten metal should be introduced over an extended peripheral portion of the lower mold section and close to the head end wall of the mold.
  • the molten metal may be introduced over substantially all of the lower half section or only a portion thereof depending on the size of the ingot.
  • the metal may enter the mold as a continuous stream between the lateral ends thereof or as a plurality of streams from closely spaced orifices or segments of the gate opening. In the latter case the streams merge and act as a continuous stream and hence for purposes of our invention the incoming metal is considered to be in stream-like form.
  • the incoming stream of metal should be relatively thin as it enters the mold, and preferably in a diverging form, and continue for but a short distance in the direction of ingot movement.
  • the lateral length of the stream is many times its width, for example, in the ratio of 15 to to 1 depending on the size of the ingot.
  • the path of the incoming metal conforms generally to the shape of the mold wall inasmuch as the metal is introduced in close proximity to the inner Wall of the mold. The proximity of the incoming metal to the chilled mold wall is important in order to obtain the desired extraction of heat from the metal.
  • close proximity we mean that the incoming metal is so close to the mold wall that some heat is immediately extracted therefrom through the mold wall as compared to the gradual loss of heat that occurs when the metal enters the central portion of the mold cavity. Moreover, the velocity of the metal stream is so small that there is no evidence of scouring of the mold surface or erosion of the surface of the freezing metal.
  • the molten metal enters the mold under a relatively low pressure such as provided by hydrostatic pressure, that is the difference in metal :level between that in the metal reservoir and the top of the ingot mold where the entire system is operating under normal atmospheric pressure. We have found that higher pressures are not required to gain the desired results.
  • the rate of withdrawal of the ingot depends upon the rate of heat extraction which in turn is determined by the mass of metal being cooled and frozen. In the case of casting circular aluminum base alloys ingots having a cross sectional area of about 28 square inches, a withdrawal rate of 6 inches per minute has been employed with highly satisfactory results. On the other hand, the rate is reduced as the cross sectional area is increased, a rectangularly'shaped ingot having a cross sectional area of 576 square inches, for example, is withdrawn at a rate of 2 to 3 inches per minute. In referring to the Withdrawal of an ingot from the mold it is to be understood that this does not imply that the metal has completely solidified as it passes the vertical plane of the discharge end of the mold.
  • Withdrawal of the ingot from the mold can be effected by any convenient means, such as described below, care being taken to maintain alignment with mold.
  • a lubricant is supplied at the head end of the mold and around the entire inner wall surface.
  • the lubricant appears to spread over mold surface and thus prevent metal-to-metal contact.
  • the lubricant is continuously supplied at a rate that provides enough lubricant while avoiding width of the slot 50 is conveniently established by choice of the external dimensions of the control ring 48.
  • the walls of slot 50 are at a small angle, between and to the inner surface of the mold.
  • the control ring 48 which is detachably mounted on the end face of the mold, can be replaced by another ring having different external dimensions which will widen or narrow the opening 50 and thus increase or diminish the flow of water onto the ingot surface.
  • the opposite side of slot 50 is defined by a tapered mold wall, the angularity of which corresponds to that of the opposing surface on the control ring 48.
  • the tapered tip at the exit end of the mold not only aids in directing the water upon the ingot surface but it provides a useful degree of flexibility for movement of the ingot in an otherwise rigid mold.
  • Lubrication of the ingot and mold wall is necessary for the continuous casting operation of the invention.
  • Various systems can be used for supplying lubricant but we have found that a low pressure system is adequate which delivers the lubricant at the head end of the mold. This can 'be achieved by providing drilled passageways 58 connected to a source of supply, and feeding the lubricant to an annular channel 34 as seen in FIG. 4. The lubricant from the channel traverses theremaining distance to the mold surface through very small radial grooves 60 distributed around the entire periphery of the mold head as seen in the enlanged fragmentary view of FIG. 5 and thereby obtain a uniform distribution of the lubricant.
  • the grooves are small enough that molten metal does not penetrate them and preferably they are normal to the surface of the inner mold wall.
  • the lubricant in the form of grease or oil is applied by known means to prevent adhesion of the ingot to the mold wall.
  • the machined end face of the mold with lubricant grooves therein can abut the refractory head plate 18, better results are obtained if the grooves are covered with a plate-like ring member 32, as shown in FIG. 4, which also serves to control extraction of heat from the freezing metal as more fully described and claimed in co-pending application Serial No. 286,349, filed June 7, 1963, now abandoned, and to its continuation application, Serial No. 542,424, filed April 13, 1966.
  • the slot gate in the header plate generally conforms to the shape of the mold but does not extend into the upper half of the mold section. However, under some conditions it may be advisable to extend the slot a short distance into the upper half sec.- tion but substantially all of the molten metal is still delivered to the lower half section of the mold. On the other hand, the slot need not extend over the full lower' half section but can be of lesser length where the ingot is large. Also, instead of a continuous aperture, the gate may be divided into segments 62 as illustrated in FIG 6 but still subject to the same limitations as the continuous slot. It is to be understood that the individual segments may be short and may even be in the form of holes arranged in a series which in effect deliver a thin stream of metal to the mold cavity. In casting a square ingot the gate 64 may assume a rectangular shape as seen in FIG. 7, while a polygonally-shaped gate 66 should be employed in casting a polygonally-shaped ingot as seen in FIG. 8.
  • a starting block is positioned in the exit end of the mold 10 and molten metal introduced to the reservoir 2 which should be preheated to prevent freezing of metal therein.
  • the liquid metal 8 immediately passes through the gate 20 into the mold cavity thereby filling the cavity defined by the mold, the starting block and the head plate 18.
  • the metal starts to freeze on the mold walls and starting block and when this has progressed to the point that the layer of metal frozen on the starting block is thick enough to be self supporting, the block and attached ingot are gradually withdrawn from the rnold and the rate of withdrawal increased until a predetermined rate is attained.
  • the starting block is detached from the ingot.
  • the ingot is generally cut into convenient lengths by a saw or other means as it moves away from the mold. It will be appreciated that adjustments are usually necessary in casting different metals and even alloys of the same base metal. Also, suitable mold materials should be employed with respect to the metal being cast. In the case of casting aluminum and aluminum base alloys, molds'can be used which are aluminum alloys since the chilling is sufficiently drastic as to prevent any melting of the mold.
  • Example 1 An aluminum base alloy having a nominal composition of 0.7% magnesium, 0.4% silicon, balance aluminum, was melted and fed to the reservoir adjacent the mold, the metal in the reservoir having a temperature of 1260 to 1280 F.
  • the mold of cast aluminum alloy had a length of 3 inches and an internal diameter of 6 inches. Water was supplied to the cooling chamber in the mold wall and projected therefrom upon the emerging ingot at the rate of 40 gallons per minute.
  • the slot gate extending over an arc of 180, had an exit width of V8 inch and the lower edge was spaced from the inner mold wall by 4 inch.
  • the body of molten metal in the reservoir was maintained at a height of about 3 inches above the top of the forming ingot thus providing a small hydrostatic pressure on the metal fed to the mold.
  • scalping When the surface of the ingot is to be worked it is usually necessary to remove the rough surface layer by machining, this operation being usually designated as scalping.
  • the cut made by scalping normally extends to a depth of inch or more. Ingots cast in the horizontal mold described above exhibited only slight evidence of liquation and hence would require but a light cut if one were necessary with obvious economic advantage to the producer.
  • Example 3 The same alloy was used as in Example 1 but the mold had an internal diameter of 9 inches and was 4 inches in length.
  • the slot gate which extended over an arc of had the same exit width and spacing from the inner mold wall as the gate described in Example 1. Water was supplied at a rate of 60 gallons per minute and the rate of ingot withdrawal was 4 inches per minute, thus reflecting the lower rate needed when the mass of metal to be chilled is increased. The resulting ingot had the same quality an excess. An excessive amount not only yields vapors that may become entrapped in the metal but may leave a carbonaceous film on the ingot surface.
  • the essential features of the apparatus comprise a molten metal reservoir, a chilled horizontally positioned mold open at the discharge or exit end and closed in the opposite end with a high heat insulating member except for the slot shaped gate for delivering molten metal in close proximity to the mold wall over substantially the lower half section of the mold.
  • Molten metal is supplied from the reservoir to the gate under a relatively low pressure.
  • a metal supply reservoir is provided immediately adjacent to the gate opening in the heat insulating member, for example, by using the heat insulating member as a common wall between the reservoir and the mold. In this arrangement the reservoir is of such a depth that the top surface of the body of molten metal held therein can be maintained above the uppermost portion of the mold.
  • the mold is provided with a jacket or chamber within the mold wall for circulating a liquid coolant and chilling the mold.
  • a preferred arrangement involves discharging coolant from that chamber upon the emerging ingot through passageways which project a sheath of coolant upon the moving ingot.
  • the chilling of the molten metal and emerging ingot in this mold arrangement is very rapid yet both the internal structure of the ingot and its surface are free from major defects.
  • Conventional power driven means are used to move the ingot from the mold.
  • FIG. 1 the general arrangement of the apparatus is seen in FIG. 1 where an open top molten metal reservoir 2 and associated supply trough 4 are covered with a suitable refractory 6, the reservoir having the general transverse shape of a U and of suflicient width to embrace all of gate in the wall member 18.
  • the back wall of the reservoir consists of a vertical platelike refractory heat insulative member 18 having an elongated aperture or slot 20 which conforms generally to the shape of the mold on the opposite side of the -wall member.
  • the choice of refractory will be determined by the nature of the metal being cast, in the case of casting aluminum and aluminum base alloys the commercial asbestos-silica product sold under the trade name Marinite is satisfactory.
  • the chilled mold 10 On the opposite side of wall member 18 and compressed against it in sealing disposition is the chilled mold 10 which can be composed of aluminum or copper where light metals are being cast. Although the mold can be made as an assembly, a more convenient arrangement is to make the mold as an integral casting and machine the surface where required as well as any passageways.
  • the mold 10 is cooled by circulation of water or other coolant supplied through pipe 14 to annular chamber 16 in the mold wall. The coolant is discharged from the chamber 16 through drilled passageways 44 to a second or mixing chamber 46 and from thence it is projected as a sheath 52 onto the emerging ingot through channel 50. Also seen in FIG. 1 is passageway 58 for continuously supplying lubricant to channel 34 from where it is fed to the head of the mold at the inner wall surface through suitable small openings.
  • the aforesaid mold 10 is supported on a framework 12 through intermediate members consisting of a heavy metal plate 26 having an opening 27 therein of slightly smaller dimensions than the outside dimension of mold 10.
  • the plate 126 is bolted to lugs on the mold, not shown, to hold the mold in place.
  • the mold is aligned and centered with the reservoir and plate 26 by means of the rabbet groove 31 in the complete-cl assembly.

  • a plate-shaped refractory insulating member 28 is placed over the ring 22, the circular opening 29 being small enough to permit the plate 26 to establish contact with refractory head plate 18 and prevent seepage of molten metal to the stepped ring 22.
  • the protecting plate 28 is secured in position through a thin metal clamping plate 30 by suitable fastener means which extend into metal plate 26.
