Definitions

  • This invention relates to molds forand methods of casting long stringed ingots of light and heavy metals and particularly of steel and steel alloys.
  • One-object 01f this invention is a mold provided with a cooling jacket which may be used for the casting-of long stringed ingots of both light and heavy metals without the foregoing disadvantages.
  • Fig. 1 is a horizontal section of a cast iron mold in accordance with the invention for th casting g1 long stringed ingots having a square cross secion:
  • Fig. 2 is a section of a part of a cast iron mold in accordance with the invention used for casting ingots having a rectangular cross section:
  • Fig. 4 is a vertical section of the mold shown in Fig. 5 is a horizontal section of another embodiment of a mold in accordance with the inven tion, and v Figs. 6 and 'l are vertical sections of the mold shown in Fig. 5.
  • a mold for the casting of long stringed ingots is constructed with a number of longitudinal walls forminga mold having a polygonal cross section such as a square or rectangular cross section orthe like.
  • a cooling jacket is provided around the mold walls in spaced relation thereto.
  • the mold walls instead of being rigidly connected to the cooling jacket are connected and held in the cooling jacket by means of mating inclined surfaces defined by positioning'guide projections or positioning means positioned on the cooling jacket and on the mold walls.
  • These mating inclinedsurfaces are inclined in a direction toward the) center of the mold'and each inclined surface should be parallel to the resultant of the lateral heat expansion of its nearest adjacent mold walls.
  • each of these projections having the mating inclined surfaces will form a continuing sealing Joint in any position or; the sliding contact, and the walls of the mold will be allowed to expand or contract within the water jacket freely without placing undue stresses on themselves or the jacket.
  • These molds may beused for casting light or heavy long stringed in-" gots, cooling the same by means of acooling jacket and yet avoiding thedetrimental and pro-' hibitive effects of the heat stresses encountered.
  • the molds in accordance with the invention may be constructed in order to allow a special method of casting long stringed ingots particularly plated ingots. According to this embodiment.
  • the molds are constructed of a substantially rectangular cross section with two opposingwalls slidably moveable together with the bottom in their plane.
  • the mating surfaces of the projec tions are mounted in slidable engagement throughout the entire range of'movement of the walls. This embodiment allows the lowering of the walls while the ingot is being cast with cool-' ing medium flowing through the cooling jacket of the new mold.
  • These moveable walls may be constructed 01' any plating material which will remain combined with the cast ingot.
  • the guide projections or positioning means are provided with one or more channels so that water which penetrates through the sliding jointsjw'ill be collected therein.
  • the walls of the mold to be lowered may be provided with dove-tailed grooves near their edge into which the molten cast metal will enter and hold fast.
  • the cooling chamber may be wholly or partially subdivided by horizontaldividing or guide walls or by several frame'lilre :molds :relatively low in height which can be put one upon another.
  • the lateral cover plates and the guide projections or positioning .means should extend over the whole height of the mold.
  • the mold so constructed may have the guide bars or positioning means of the nonemoveable side walls extended beyond the mold.
  • the cooling chambers adjacentto the walls may 'he provided with reinforcements running ,parallel to the walls and .at .a small distance therefrom.
  • These reinforcementsa should have the shape .of bars, perforated walls-or the like and should consist preferably of ametal having .a relatively high eoe'fiicient of .expansionsuch as strong .life metal alloys .and the like.
  • the plates which constitute the side walls of the mold should be firmly and tightly connected to the walls defining .the frontsides ofthemold.
  • a piston head is arranged in a known manner so that .a long stringed ingot can be lowered.
  • the expansion joints between the outward extending walls of the mold-bottom, and .the ad-J'acentcooling chamber walls maybe subdivided as in a steplike fashion in order to form stops and/or vertical outlet channels.
  • the .wallsof the mold bottom and the .outer cooling chamber walls should engage each other in an angular direction extending toward the center of the mold.
  • Theclosedmold may be used in either .a vertical, inclined .or horizontal position provided that the ifeedinghead is correspondingly built.
  • the inventiomthe joints which run horizontally hetween-the mold proper and the cooling jacket. are defined'by mating adjacent surfaces whichare inclined in the direction of the resultant .of the longitudinal and lateral expansion .of the inner mold.
  • the long stringed ingot .casting mold should have sealing joints defined by the inclined surfaces of the inclined positioning means or guide projections at the 'four vertical edges, the
  • the outer mold body 3 consists of two parts surrounding the mold I, I and forming cooling chambers 4 through which a cooling medium, preferably water is flowed.
  • the casing 3 has guide projections or positioning means 5 projecting towards the inside; the Zfront edges of the projections defining the sliding surfaces 1 for guide projections 6 which are attached to projecting parts of the two opposite walls I.
  • the plane of the surfaces faces I of the projections '5 and 8 lie parallel to the resultant of the lateral expansion of the casting mold l and I' at its corners.
  • the .plane of the surfaces 1 and the -wa'lls I or I' have an inclination to each other of about 45. Compressive stresses are thereby completely avoided at the guide surfaces which displace themselves by sliding along one another while exerting a small, more or less constant, surface pressure therebetween.
  • theinner mold consists of the. plates I and U-sha'pedmlate I which are welded together .at 2.
  • the :outer mold 13 is'closed'at its front .by thecoverifnthe sidesurfaces of which are, according ;to therprinciple already mentioned, :placed .in thedirection of the resultant of the longitudinal and lateral expansion .of :the mold walls. These. surfaces are stepped at .8.
  • the guide projections 6 are .connected with theprojecting edges "ofthe walls I and the legs of the U-shaped walls TI".
  • In the end walls :of the outer mold 3 there are.zprovided channels 9 through which cooling water which may enter throughthe sl-idings'urfaces' will run downwards.
  • the walls I of the mold consist preferably f plating material, and are lowered together with the ingot as it is cast.
  • the plates I andthe guide projections 6 arefastened together with bolts by means of angles II or the like.
  • the projections B are also lowered.
  • the plates I may, as already mentioned, consist'of any plating material such as copper, nickel, a high alloyed stainless steel orthe like.
  • FIG. 4 illustrates the plates I together-with the guide bars 6 projecting beyond the other parts "of the mold.
  • the mold body 3 is arranged on a corresponding frame 3".
  • The'inner mold, ji. 6.. the mold proper is closed at its bottom by means of the bottom piece I2 fitting the 'interioriolf the mold, and-which can be lowered by means of the piston rod I3 and the hydraulic piston I4 moving in the cylinder I5.
  • the bottom piece I2 may, however, also be loweredby purely mechanical means, e. -g., by means of a screw spindle, .raicks. fluted roller, or .thelike.
  • the bottom piece 42 carries the "plates I to be loweredjand supporting means It extending downwards, said supporting means having at their lower ends crossflplates I?” to which the guide projections 6 are attached.
  • the projections 6 are, as shown by way of example in Fig. 1, propped by bars I8, perforated walls, or the like. These bars stiffen the walls and consist preferably of a meta1 which has a relatively high coefficient of expansion (light metal). These bars are placed at a small distance from the walls I.
  • the guide projections can also be made broader and reinforced around the mold I, I' by additional supports I8.
  • Figs. 5-7 of the drawings similar parts have the same references as in Figs. 1-4.
  • the projections 5 are so inclined that all planes of surfaces I intersect in a common line AA (Fig. 6 and7) There is no need that this line go through the center of gravity of the whole system and can even lie outside of one of the plates I. In the latter case, one pair of the surfaces I are inclined on an angle whereas the other pair may have a correspondingly greater inclination.
  • the planes of sealing surfaces I are inclined so an extension thereof willform the planes P of a pyramid having an apex O which lies on the line AA.
  • the line AA be the central axis of the whole system in order to attain the same inclination of all the surfaces I'.
  • the projections 6' are heated less than the plates I and I respectively and that they have therefore a relatively smaller expansion. This fact, however, need not be considered to any great extent due to the great height of the surfaces I and I as compared to the height of the projections.
  • ingot casting comprising means defining a number of mold walls defining an inner longitudinally extending mold of polygonal cross section, a cooling jacket around said mold in spaced relation thereto, first positioned means carried by said mold for pcsitioning the same within said cooling jacket and defining a first surface inclined in a direction toward the center of the mold and substantially parallel to the resultant of the lateral heat expansion of the nearest adjacent walls of the mold, second positioning means carried by said jacket and defining a second surface in substantially slidable mating contact with said first surface.
  • said mold is substantially rectangular in cross-section, in which each one of one pair of opposed walls of said mold is slidably movable in its plane together with the bottom of said mold, in which the mating surfaces of said second positioning means extend throughout the range of sliding movement of said movable walls and in which the mating surfaces of said first positioning means are mounted for slidable engagement with the mating surfaces of said second positioning means in the direction and throughout the range of movement of said movable walls.
  • said third and fourth positioning means substantially define at each end closures for the cooling chamber defined between the jacket and the mold, and in which mating surfaces define slidable sealing joints for each said closure.
  • said mold is substantially rectangular in cross-section, in which each one of one pair of 0pposing walls of said mold is slidably movable in its plane together with the bottom of said mold, in which themating surfaces of said second positioning means extend throughout the range of sliding movement of said movable walls, in which the mating surfaces of said first positioning means are mounted for slidable engagement with the mating surfaces of said second positioning means in the direction and throughout the range of movement of said movable walls, and in which said movable walls are removable from said mold to form an ingot cladding.
